Answer 1

Answer:

8. D

9. A

10. A

11. C

12. D

Explanation:

8. Natural selection works on variation that exists in the genes of organisms. Antelopes who have genetic variation that makes their legs more muscular are at an advantage because they can outrun predators. This increases the chance that they will reach reproductive age, and be able to pass this advantageous trait onto their offspring. Over time, this selection pressure makes the variant more common in a population.

9. Beneficial traits are those that give a selective advantage. This could be one that helps it outrun predators (like above), avoid illness and death, gives it a reproductive advantage (i.e. more attractive to mates), or makes it better able to digest certain foods, for example. The formation of cancer cells would be harmful for an organism, reducing its fitness and perhaps leading to death. The inability to reproduce would mean genetic info is not passed on to the next generation, and stopping the production of an essential protein would likely lead to death. However, resistance to a virus would help an organism avoid illness and death, improving fitness.

10. Genotypes are what organisms inherit from their parents, i.e. the genetic information that is passed on. However, the way in which different alleles interact and are expressed is the phenotype. If we take the above example, natural selection is acting on the phenotype of muscular legs. If an antelope had the muscular leg genotype but for some reason it was not being expressed (maybe another gene is interfering with it), then the antelope would not have a selective advantage, and natural selection could not be act on the trait.

11. A trait that better suits an organism to its environment will be selected for by natural selection. This is because that organism is more likely to survive due to the trait, giving it a selective advantage. Therefore, if a mutation arose making the giraffe more adapted to the environment, it would be positively selected for, and through evolution would become more common.

12. This is an example of selective breeding, which has been happening for generations. Farmers spot desirable traits, and cross horses with these traits in an attempt to enhance the trait or to ensure it is passed on to the next generation. This is not natural selection, because farmers are making it happen artificially. It is not cloning or recombinant DNA, which are terms scientists use for actually manipulating the DNA in the lab.

What are 2 things you find on a phylogenic tree? Thank you

Answers

Phylogenetic tree enriches our understanding of how genes, genomes, species (and molecular sequences more generally) evolve.

Explanation:

A phylogeny, or developmental tree, speaks to the transformative connections among a lot of life forms or gatherings of living beings, called taxa (particular: taxon). A phylogenetic tree can help follow an animal groups back through transformative history, down the parts of the tree, and find their normal family en route.

The foundation of a phylogenetic tree shows that a tribal heredity offered ascend to all life forms on the tree. A branch point demonstrates were two genealogies separated. A genealogy that advanced early and stays unbranched is a basal taxon. At the point when two heredities come from a similar branch point, they are sister taxa.

A cell has 38 chromosomes. After mitosis and cell division, one daughter cell has 39 chromosomes and the other has 37. What might have caused these abnormal chromosome numbers? What effects do you suppose this might have on cell function? Why?

Answers

Aneuploidy is the condition that occurs when daughter cells are formed with unequal or abnormal number of chromosomes after mitosis and cell division.

Explanation:

Aneuploidy occurs when homologous chromosomes fail to segregate or rearrange leading to chromosomal nondisjunction. This condition leads to genetic mutations, giving rise to abnormal number chromosomes in the daughter cells, where (2n+1) or (2n-1) haploid daughter cells are formed instead of 2n chromosomes.

Trisomy is the aneuploidic condition caused when there is a third chromosomal (2n+1) copy instead of two copies, which has occurred in the given case leading to formation of daughter cells with 39 chromosomes instead of 38.

Aneuploidy disrupts cell function and can lead to organ malformation as in Down's syndrome, cell multiplication leading to cancers, etc due to disturbance of protein homeostasis.

How can some pain relievers work to reduce pain signals at the synapse?

Answers

Answer:

Opioid pain killers block synaptic transmission of nerve impulses by binding to opioid receptors.

Explanation:

Different types of pain medication have different mechanisms of action. These pain medications are broadly classified as:Non-opioid pain killers that include aspirin and ibuprofen. These work by inhibiting the enzymes responses for producing the pain signals at the site of injury or source of pain. These enzymes, known as COX-1 and COX-2 produce a chemical called prostaglandin. This hormone transmits the pain signals to the nervous system.Opioid pain killers, such as codeine, morphine and oxycodone, physically block the synaptic transmission of the pain signal. They bind to receptors known as opioid receptors. Opioid receptors are G-protein coupled receptors (GPCR). In cell signaling, GPCRs are receptors that activate/inhibit signaling pathways through activation/inhibition of adenylyl cyclase, an enzyme that producing cAMP, a second messenger that regulates the K+ and Ca+2 channels responsible for nerve impulse transmission. Opioid pain killers inhibit adenylyl cyclase consequently reducing cAMP production. This blocks Ca+2 channels and opens K+ channels in the neurons, thereby reducing neuron excitability and the release of neurotransmitters.

     3. Adjuvant pain killers are used to treat neuropathic pain i.e. pain due to injury of the nervous system.

Which layer of the atmosphere is most strongly affected by conditions on Earth's surface?

A) Thermosphere
B) Troposphere
C) Stratosphere
D) Mesosphere​

Answers

Final answer:

The Troposphere, extending up to 12 km above sea level and encompassing about 80% of the Earth's atmosphere, is directly influenced by Earth's surface conditions. This is because it generates weather events due to convection currents formed by the heated air rising from Earth's surface and cooler air descending, which equally affects the wind and cloud formations in this layer.

Explanation:

The layer of the atmosphere most strongly affected by the conditions on the Earth's surface is the Troposphere, option B. The troposphere extends up to 12 km above sea level and contains nearly 80% of the Earth's atmosphere by mass. It is the layer where most weather events originate owing to the hot air rising from the Earth's surface and colder air descending. Hence, conditions on Earth's surface predominantly influence this layer of the atmosphere.

For example, the convection currents in the troposphere are directly impacted by the heating of the Earth's surface, generating wind and cloud formations. This dynamic nature of the troposphere is the reason for its direct susceptibility to the surface conditions of the Earth.

https://brainly.com/question/26767532

#SPJ12

The troposphere is the layer most strongly affected by conditions on Earth's surface. So option (b) is correct.

The troposphere is the layer of the Earth's atmosphere closest to its surface, extending from the surface up to about 10-15 kilometers (6-9 miles) high.

It is where weather occurs and where most of Earth's clouds and precipitation are found. The conditions in the troposphere, such as temperature, humidity, and air pressure, are directly influenced by conditions on Earth's surface.

For example, during the day, the surface heats up, causing air near the surface to warm and rise, leading to convection currents and the formation of clouds and storms. At night, the surface cools, causing the air to sink, which can result in calm and clear conditions.

Therefore, the troposphere is the layer most strongly affected by conditions on Earth's surface. Other layers like the stratosphere, mesosphere, and thermosphere are less directly influenced by surface conditions.

The scientific method is the process that scientists use to find out new information. It involves a question, a hypothesis, a prediction, collecting data, and analyzing that data to make a conclusion. How would you use the scientific method to answer this question: Do pumpkins grow bigger when fed milk? (Use each of the steps of the scientific method in your answer.)


State one scientific question.


State one nonscientific question.

Answers

The calcium present in the milk acts as a fertilizer, for the growth of pumpkin size.

Explanation:

Scientific answer: Milk contains nutrients, minerals mainly calcium which are good for the growth of the plant as a fertilizer.

Milk gets readily absorbed by the roots due to the solubility of nutrients in milk.

The root hairs of the plant transport the calcium to the other parts like stem.

This will only help when all other factors of plant growth are present as sunlight, water other than fertilizer.

Non-scientific question:

The Hypothesis here is those pumpkin plant fed with milk are bigger on size.

Also injecting stems with milk would cause no good.

Pumpkin plants fed with milk and some plants fed with water are compared, we get the result that giant pumpkins are one that are fed with milk. This is  statistical analysis.

Final answer:

To apply the scientific method to the question of pumpkin growth with milk, one would form a hypothesis based on research, conduct an experiment with controlled variables, collect and analyze data, then draw a conclusion. A scientific question could ask about the effect of milk's calcium on pumpkin growth, while a nonscientific question might inquire about taste preferences for such pumpkins.

Explanation:Applying the Scientific Method to Study Pumpkin Growth

Using the scientific method to determine if pumpkins grow bigger when fed milk would involve several steps. First, an observation must be made, which in this case, might stem from the anecdotal evidence that soil enriched with milk could enhance plant growth. This leads to the question: "Do pumpkins grow bigger when fed with milk compared to water?" A thorough literature review should be conducted to see if previous research can inform the hypothesis.

Next, a hypothesis is formed, which is an educated guess based on the research. For example, the hypothesis could be "Pumpkins fed with milk will grow larger than those fed with water due to the additional nutrients found in milk." We then make a prediction that is testable through experimentation, such as "If pumpkins are fed milk over a growing season, they will gain more mass compared to those fed just water."

Sheep would then be cared for in a controlled way for a period of time, with one group receiving milk as a part of their feeding regimen and another group only receiving water. Data on pumpkin size, weight, and overall health could be collected throughout the growing period.

Once the data is collected, it is analyzed statistically to determine if there is a significant difference between the two groups. Finally, a conclusion is drawn, which either supports or refutes the hypothesis, leading to further questions and research in a cyclical pattern of scientific investigation.

A scientific question related to this experiment could be "Does the calcium content in milk contribute to the increased growth of pumpkins?" A nonscientific question could be "Do people prefer the taste of pumpkins that have been fed milk?" The former relates to measurable scientific phenomena while the latter relates to subjective personal preference.

b. Aa;BB;Cc;Dd
c. AA;Bb;cc;DD
d. AA;BB;cc;dd

Answers

d) AA;BB;cc;dd genotypes will be rarest to observe among the progeny.

Explanation:

Let us cross the given alleles of the gene

Aa X AA                   Bb X Bb       Cc X cc       Dd X Dd

                                         

   A  a                         B    b             C   c             D  d

A  AA  Aa                 b Bb  bb         c  Cc   cc     d Dd   dd

From the above results of crosses, it can be concluded which of the genotypes is rarest among the progeny. The genotype ratios in:

In the first case it can be both as they are in the ratio of 2:2

In the second case 1:2:1

in the third case  2:2

in the fourth case 1:2:1

So least occurring genotypes are

AA;BB;cc;dd

AA;BB;cc;dd genotypes will be the rarest to observe among the progeny

d. AA;BB;cc;dd

Explanation:

AaBbCcDd X AABbccDd

Aa X AA - AA, AA, Aa, Aa - Genotypic ratio = 1:1

Bb X Bb - BB, Bb, Bb, bb - Genotypic ratio = 1:2:1

Cc X cc - Cc, Cc, cc, cc - Genotypic ratio = 1:1

Dd X Dd - DD, Dd, Dd, dd - Genotypic ratio = 1:2:1

We can see that the heterozygous combinations occur more in number.

Whereas, Homozygous recessive appears the least.

Therefore, the rarest to observe among the proge is AABBccdd as is has two recessive combination.

What is the name of the shaded part of the sound longitudinal wave shown? A) amplitude B) compression C) crest D) rarefaction

Answers

Answer:

B) compression

Explanation:

First of all, we must highlight that the question above refers to a sound wave. Sound waves are longitudinal waves, because they have the ability to propagate through the air, as the sound takes over the environment. This spread creates regions known as compression and rarefaction. The rarefaction presents a greater space between the movement of the wave, where the air can interfere, since the compression allows the sound waves to be closer together, with little air interference (we can see this in the figure above, in the shaded part where the waves are present very close to each other). Wave compression has the ability to propagate within solid materials, allowing a vibration to be created that is picked up by our ear.

Answer:

B) Compression

Describe how the lac operon functions and explain how it permits E. coli to produce the enzymes needed to break down lactose when it is present in the bacterium.

Answers

Answer:

An operon consists of a group of genes which are controlled by a single promoter.

The lac operon present in the E.coli comprises of genes for making proteins which  breakdown lactose into glucose.

Normally, the lac operon will be turned of by a repressor when there is not enough lactose present.

When lactose is present in the cell, the operon is activated when lacl forms a bond with the promoter region due to its changes in the structure. This causes the process of transcription to occur.

Answers

Answer: 1). Lungs

2). Heart.

Explanation:

Even though the options were not provided, generally all arteries carry oxygenated blood except the pulmonary artery while all veins carry deoxygenated blood except pulmonary vein.

Pulmonary artery and veins are responsible for pulmonary circulation. Pulmonary circulation involves the transport of deoxygenated blood from the heart to the lungs by the pulmonary artery where the carbon dioxide is removed and the blood gets oxygenated; and the transport of the oxygenated blood from the lungs to the heart by the pulmonary veins from where they are being carried by other arteries to other parts of the body.

Pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs where the carbon dioxide entrapped in the deoxygenated blood is offloaded and oxygen is loaded in the blood, thereby causing the blood to become oxygenated.

Pulmonary vein then carries the oxygenated blood from the lungs into the left ventricle of the heart, from where it is supplied to other parts of the body through other arteries.

Therefore, a defect in pulmonary artery will result in short supply of deoxygenated blood to the lungs while a defect in pulmonary vein will lead to shortage of oxygenated blood in the heart.

And what is Ann’s genotype?

Answers

a. alkaptonuria appears to be caused by a recessive allele.

b. Ann's genotype is homozygous recessive (aa), meaning she inherited two copies of the recessive allele for alkaptonuria from her carrier parents.

a. Based on the pedigree, alkaptonuria appears to be caused by a recessive allele. This is because affected individuals are represented by colored circles and squares, indicating that they have the disorder. In a recessive inheritance pattern, individuals need to inherit two copies of the recessive allele (one from each parent) in order to have the disorder. If the disorder was caused by a dominant allele, only one copy of the allele would be needed for an individual to be affected.

b. To determine Ann's genotype, we need to analyze the information provided in the pedigree. Ann is represented by a colored square, indicating that she is affected by alkaptonuria. Since alkaptonuria is caused by a recessive allele, Ann must have inherited two copies of the recessive allele (one from each parent) in order to be affected.

Since Ann's parents are not affected (unaffected individuals are represented by empty circles and squares), they must be carriers of the recessive allele. A carrier is an individual who has one copy of the recessive allele but does not show any symptoms of the disorder. When two carriers have a child, there is a 25% chance for the child to be unaffected, a 50% chance for the child to be a carrier, and a 25% chance for the child to be affected.

Therefore, Ann's genotype is homozygous recessive (aa), meaning she inherited two copies of the recessive allele for alkaptonuria from her carrier parents.

Darwins u postulates

Answers

reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

Final answer:

Natural selection occurs when there is a variation of traits, the heritability of these traits, competition for limited resources, and differential survival and reproduction (fitness) which leads to evolutionary changes in a population.

Explanation:

To understand Darwin's theory of natural selection and what must be occurring in a population for it to take place, we must consider Darwin's four postulates. These factors are essential for the mechanism of evolution through natural selection.

Variation of traits among individuals in a population. This genetic variation is crucial because, without it, there would be no differences upon which natural selection could act.These variations must be heritable, meaning that they can be passed down through generations. This allows for the favorable traits to be accumulated over time.There must be competition for resources. Since resources are limited, not all individuals can survive and reproduce, leading to a 'struggle for existence.'Individuals with traits that give them an advantage in their environment are more likely to survive and reproduce. This differential survival and reproduction is known as fitness, and over time, this can lead to changes in the population.

These principles form the basis of Darwin's theory of natural selection, illustrating how populations change over time and how new species can evolve.
