The Venn diagram details some of the helpful and harmful effects of bacteria. In what ways are viruses like bacteria?
A. Viruses are also pathogenic
B. Viruses are also decomposers
C. Viruses are also prokaryotes
D. Viruses can also cause food to spoil

Answer: (C)

Explanation: well bacteria is what decomposes and eats the nasty food or dead things that are no longer living. The bacterias eat on these things causing them to break down in to nutrients which are very very good for plant growth. If we didnt have our bacteria things would not decompose fast enough making nutrients for plants almost impossiable and if this happend animals would not be able to feed of plants or trees

If you could i really need brainlist it would be greatly appreciated :)

In a food web, if bacteria were missing, the community would likely face reduced decomposition rates, resulting in fewer nutrients available for plants. Bacteria are key to decomposition, converting dead organisms and waste into simpler substances for plants to use as nutrients. Without bacteria, this nutrient cycle would be affected.

In this food web, if bacteria were truly absent, the most likely effect on the community would be reduced decomposition rates, which would in turn prevent nutrients from being recycled back into the soil for plants to use. This can be represented by option C: Decomposition rates would be lower, resulting in fewer nutrients being available to the plants.

Bacteria are a crucial part of the decomposition process as they break down dead organisms and waste products, converting these materials into simpler substances that can be used by plants as nutrients. This cycle is essential in every ecosystem as it ensures that nutrients are not lost but are instead recycled. Hence, without bacteria, this decomposition process will be hindered, affecting nutrient cycling and the health of the community.

Nucleic Acids

Explanation:

Nucleic acids are made out of nucleotides and they come in two forms: Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA). DNA holds the code of life, in other words, it holds the code for making proteins that are essential in building cells, tissues, and organs. DNA is found in the nucleus of a cell.

Answer:

A) oxidative phosphorylation

Explanation:

cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Oxidative phosphorylation is the mechanism in cellular respiration which produces the most ATP. It is the last stage of cellular respiration and can generate up to about 34 ATPs per glucose molecule.

During the process of cellular respiration, the mechanism that produces the most ATP is oxidative phosphorylation(A). This process is the final stage of cellular respiration and occurs in the mitochondria. Its main function is to transport electrons from NADH and FADH₂ through the Electron Transport Chain (ETC) to oxygen, which serves as the final electron acceptor. This process results in the formation of water and the generation of a proton gradient, which subsequently powers ATP synthesis. Compared to the other options, substrate-level phosphorylation, oxidation-reduction reactions, and oxidation reactions, oxidative phosphorylation produces significantly more ATP - up to about 34 ATPs per glucose molecule.

Final answer:

The description of the jaguar pertains to its ecological roles as a top predator, a contributing factor to nutrient recycling through decomposers, and its support to biodiversity and forest dynamics through habitat provision and seed dispersal.

Explanation:

The jaguar's role in the rainforest ecosystem can be described by addressing various ecological aspects. Jaguars are top predators that regulate populations of other species by hunting and consuming them. This ensures species do not overpopulate and resources are not depleted. As part of the food web, jaguars control prey populations and maintain the balance within their ecosystem.

Jaguars also contribute to nutrient cycling through their waste. Decomposers such as fungi and bacteria break down these organic materials, releasing nutrients back into the soil, which are essential for plant growth and help sustain other organisms in the rainforest. This includes macro and micro elements like nitrogen and phosphorus.

Beyond that, jaguars support biodiversity by providing habitats for various microorganisms in their fur and by acting as hosts for parasites. Lastly, as large mammals, they can affect the forest dynamics through seed dispersal via their droppings, promoting plant diversity and forest regeneration.

Thus, this description details the jaguar's ecological roles in the rainforest, including predator control, nutrient recycling, and habitat provision, as well as seed dispersal, reinforcing their status as a keystone species in their habitat.

Answer:

1. B.

2. B.

3. A.

Explanation:

1. So, the mother does not but the father does carry the gene for polydactyly. Which means that, the offspring was born Pp and, the dominant trait (P) was exposed.

2. A heterozygous trait is one that has both allele forms (in this case, d and D. If both of the parents are Dd, the offspring will also be Dd, and therefore, he has 1/2 chance of being born deaf.

3. Both you and your spouse will be heterozygous (Ee), therefore, since unattached earlobes are dominant

3.1 When two heterozygous traits are bred, you will get the following combinations: yy, Yy, Yy and YY. Which means that your offspring had a 1/4 chance of having attached earlobes, and that is what happened.

3.2 The third option is incorrect, because when you breed 2 homozygous recessive (ee) traits, all of your offspring will be homozygous recessive (ee), which means that the parents would have to be homozygous recessive, but, they cannot since the dominant trait has applied to them.

Answer:

The correct option is D.

Explanation: The options attached to this question are given below:

A) Bacteria from other animals replace those killed by the antibiotics.

B) The few surviving bacteria that are affected by the antibiotics develop immunity to the antibiotics, which they pass on to their progeny.

C) The antibiotics cause new mutations to occur in the surviving bacteria, which results in resistance to antibiotics.  

D) The antibiotics kill susceptible bacteria, but the few that are naturally resistant live and reproduce, and their progeny repopulate the host animal.

E) The antibiotics persist in soil and water.

Antibiotics are sometimes used in animals to control infections. With time, the microbes that are been targeted with the antibiotics usually develop mutations, which makes the antibiotics to become ineffective, thus, the antibiotics will only be able to kill the susceptible microbes while the ones that have developed resistance will remain and give birth to young ones that are also resistant to antibiotics.

The practice of adding antibiotics to animal feed results in the development of antibiotic-resistant bacteria because it encourages the survival of resistant strains, which can be transmitted to humans.

The use of antibiotics in animal feed leads to antibiotic-resistant bacteria because these drugs are given to livestock in low doses, which promotes the survival and reproduction of bacteria that are naturally resistant to antibiotics. In the United States, it is estimated that 70% of the antibiotics produced are fed to animals as a way to enhance production, rather than to prevent disease. This practice encourages the natural selection of resistant strains of bacteria, which can then be transferred to humans, increasing the challenge of treating bacterial infections effectively. The emergence of antibiotic-resistant bacteria due to the excessive use of antibiotics in livestock highlights the need for more judicious use of these drugs, including regulatory changes and increased public awareness.

Photosynthesis is the answer, I'm like 85% sure...

Answer:

25% ;  50%

Explanation:

Assuming the dominant allele for the rolling tongue is P, then the recessive allele will be p.

The population unable to roll their tongue will be recessive dominant pp = 25% = 0.25

To find the frequency of the p allele then = (square root of 0.25) = 0.5

Remember the Hardy Weinberg equation of p + q = 1 & p² +2pq + q² = 1

Therefore P = 1 – 0.5 = 0.5

Homozygous dominant individuals will be P*P = 0.5*0.5 = 0.25 * 100 = 25%

Heterozygous individuals will be 2*P*p= 2*0.5 *0.5 = 0.5 * 100 = 50%

Answer:

RNA polymerase attaches to the promoter

Explanation:

Transcription is the process of synthesis of RNA using DNA as template. RNA polymerase enzyme binds to promoter region of the gene and starts making RNA strands that has complementary nucleotide sequence to DNA template strand. The process stops as the enzyme RNA polymerase encounter terminator sequence of gene.

The first step for transcription to begin is initiation, where the RNA polymerase enzyme attaches to the promoter on the DNA molecule. This process triggers the start of transcription and allows for the synthesis of the mRNA transcript.

Transcription in biology begins with the process called initiation. During initiation, a specific region on the DNA molecule, known as a promoter, triggers the start of transcription. The RNA polymerase enzyme attaches to the promoter and begins reading the DNA template, synthesizing the mRNA transcript in a 5' to 3' direction.

Answer:

The correct answer would be option B.

Avery experiment proved that DNA is used as the genetic material in most of the living organisms.

It can be explained with the help of observation that when the S bacteria were treated with DNAase, they could not transfer their DNA to the R bacteria. Consequently, R bacteria did not transform into S bacteria.

In contrast, when these bacteria were treated with protease or RNAase, they could transfer DNA easily due to which R bacteria could easily transformed into S bacteria.

Answer:

B

Explanation:

When heat-killed nonvirulent S bacteria will be treated with enzymes that degraded DNA it will destroy the genetic information required for cell survival. DNA is very essential for an organism and is called the molecule of life. DNA degradation is also a part of cell death called apoptosis. That's why all the samples grew except the one where DNA was enzymatically degraded.

The outcome would be different as the nerve cells in squids are much bigger than those of humans.

Answer:

May get a better understanding or may not be able to explore the nerve cell due to its small size as compared to squid nerve cells/axon

Explanation:

Biologist and scientist are aware of the fact that each and every nerve cell is essential for proper molecular functioning of body. The sodium/potassium pump is essentially important for all the cells and hence it is considered by biologist to take out human nerve cell and conduct research on it. Thus they prefer using squid nerve cell.  

Also scientists prefer to use squid axons because they are exceptionally large (with 1 mm width and length of even 1 meter) due to which it is easy to study their counter parts. Their manipulation for research work is also easy and hence all basic researched till date have helped scientist to develop a better understanding electrical signal and henceforth the driven system.

The parasite would affect the brain of the lynx and the brain of the hare

Explanation:

Toxoplasma gondii is a parasite that is able to infect pretty much every warm blooded animal on the planet. It is an obligate intracellular parasitic one-celled eukaryote. This parasite manages to cause the infectious disease known as toxoplasmosis which damages the brain. The hare is a warm blooded animal, and it can be infected by this parasite. If the hare is infected and a Canadian lynx kills that particular hare and consumes it, then the lynx will also be infected with the parasite. The parasite will cause damage to the lynx's brain which will result in the dying of that lynx.

Answer:mismatch repair

Explanation:proof reading is a process through which the mistakes that were made during the process of replication of DNA are corrected and if they are corrected after replication of DNA the process is called mismatch repair .

DNA Mismatch repair also called as MMR is a system for recognizing and repairing the DNA for unwanted insertion, deletion, and mis-incorporation of bases that can arise during DNA replication and recombination, as well as repairing some forms of DNA damage.

The repair pathway that corrects mismatches caused by the failure of DNA polymerase to recognize an incorrect nucleotide is known as mismatch repair. Specific enzymes identify and correct the errors to maintain genetic stability.

When DNA polymerase fails to recognize an incorrect nucleotide resulting in a mismatch, the repair pathway that corrects this mistake is known as mismatch repair. This process involves specific repair enzymes that scan the newly synthesized DNA for errors. In bacteria like E. coli, the parental DNA strand is distinguished from the newly synthesized one by methyl groups, allowing the repair enzymes to identify and correct errors on the non-methylated strand. In eukaryotes, the exact mechanism of mismatch recognition is not well understood, though it may involve identifying unsealed nicks in the new strand and association with replication proteins.

If errors are not corrected by mismatch repair, it can lead to more permanent damage when the DNA is replicated again. This system serves to greatly reduce the error rate of DNA replication, improving genetic fidelity and thereby contributing to maintaining the stability of the organism's genome.

Final answer:

Haiti continues to face challenges following the 2010 earthquake, including public health problems like cholera due to a lack of potable water, and social issues stemming from its vulnerability to natural disasters such as earthquakes and hurricanes.

Explanation:

Haiti Earthquake and its Aftermath

More than half a decade after the magnitude 7.0 earthquake that struck Haiti on January 12, 2010, the country continues to face severe public health and social challenges. The earthquake's epicenter was near the capital, Port-au-Prince, causing widespread destruction including the collapse of the National Palace and the majority of governmental offices, with estimates of over 160,000 fatalities and approximately 1.5 million individuals displaced. In the aftermath, inadequate housing, political corruption, and the spread of diseases like cholera compounded the difficulty of recovery efforts.

Haiti's struggle with public health crises was exacerbated by an outbreak of cholera, ironically introduced by United Nations peacekeepers. The lack of access to potable water is a significant issue, with 35% of the population lacking basic drinking water even before the earthquake occurred. These conditions created a fertile ground for the transmission of disease, perpetuating the cycle of poverty and instability.

The geographic location of Haiti on a tectonic plate boundary not only makes it prone to earthquakes but also exposes it to hurricanes. Significant damage from natural disasters in the past, including Hurricane Matthew in 2016, has repeatedly impacted the country's infrastructure and development efforts, leading to ongoing public health and social problems that are still being addressed today.
