Answers

Answer 1

Answer: C.ecosystem services

Explanation:

The ecosystem services are the benefits that are received by human kind from the natural environment. These benefits includes the forest ecosystem, aquatic ecosystem and grassland ecosystem.

The chemicals, medicines, food and water are the services that human kind receives from ecosystems. The natural ecosystems are also responsible for controlling the disease, climate and nutrient cycles, aids in the production of oxygen and also aids in maintaining the recreational benefits.

The pharmaceutical products obtain from the wild life are also the sources of ecosystem services.

Evolution explains both the unity and diversity of life. Explain how evolution can account for both why anoles and finches share certain traits and also why they differ.

Answers

Final answer:

Evolutionary processes through natural selection acting on genetic variation explain the unity and diversity observed among species. Convergent evolution results in similar traits in different species, while divergent evolution leads to differences within groups that have common ancestors. Mutations drive the genetic variation that fuels these evolutionary processes.

Explanation:

Evolutionary processes account for both the commonalities and differences between species such as anoles and finches. The theory of evolution is underpinned by the idea that all life is related and that modifications occur over time through natural selection acting on genetic variation.

On the one hand, convergent evolution explains how different species may develop similar traits as a result of adapting to similar environmental pressures. This leads to the unity of various life forms that look superficially similar due to similar selection pressures even though they might not be closely related genetically.

On the other hand, divergent evolution or adaptive radiation accounts for the diversity we see within groups of closely related organisms. Even though species like anoles and finches may share a common ancestor, the different environmental niches they occupy have pushed them to evolve distinct traits.

These differences highlight the adaptability and variation within species that result from the differential survival and reproduction of individuals with favorable traits. As environments change or as species spread into new habitats, natural selection favors different traits, leading to further diversification.

Variation within populations is driven by mutations, creating the genetic differences that are the raw material for evolution. The consistent yet various biological structures, behaviors, and adaptations seen in the living world all illustrate the balance of unity and diversity explained by evolutionary theory. It is this balance that has led to the rich tapestry of life we observe around us today.

A female fly, full of fertilized eggs, is swept by high winds to an island far out to sea. She is the first fly to arrive on this island and the only fly to arrive in this way. Thousands of years later, her numerous offspring occupy the island, but none of them resembles her. There are, instead, several species, each of which eats only a certain type of food. None of the species can fly and their balancing organs (halteres) are now used in courtship displays. The male members of each species bear modified halteres that are unique in appearance to their species. Females bear vestigial halteres. The ranges of all of the daughter species overlap.If the malesʹ halteres have species-specific size, shape, color, and use in courtship displays, and if the speciesʹ ranges overlap, then the speciation events may have been driven, at least in part, by which of the following?
A) autopolyploidy
B) allopolyploidy
C) species selection
D) sexual selection
E) habitat differentiation

Answers

Answer:

The correct answer is option D) "sexual selection".

Explanation:

Sexual selection is a type of natural selection at which species of one sex chose their biological mates based on specific traits that represent an advantageous trait for the species. In this case, if the males halteres are used in courtship displays and the females select them in base of its size, shape and color, the speciation events may have been driven, at least in part, by sexual selection.

The correct answer is sexual selection.

Which statement about an action potential is true? 1. It "skips" over segments of myelin, hopping from one node of Ranvier to the next. 2. It is a neurotransmitter that relays messages from motor neurons to muscles, enabling movement.3. It defends the brain from infection and inflammation.4. It has a nucleus containing DNA.

Answers

Answer:

1. It "skips" over segments of myelin, hopping from one node of Ranvier to the next.

Explanation:

The action potential is the electrical signal. It is produced in neurons and muscle cells to propagate the nerve impulse. It is fired when the membrane of a neuron is depolarized.  Myelinated axons exhibit saltatory conduction of action potential. This means that the action potential is propagated from one node of Ranvier to the next while skipping the in-between myelinated region. This occurs since the voltage-gated channels are mainly concentrated at the nodes of Ranvier. Therefore, the action potential is mainly carried at nodes where Na+ and K+ flow across the membrane.

The body's internal environment is separated into compartments by barriers, including epithelial barriers, which may or may not allow for the movements of molecules from one compartment to the next. Which of the following terms most accurately describes these membranes? Semipermeable or selectively permeable

Answers

Answer:

Semi Permeable or selectively permeable

Explanation:

The multicellular organisms are made of the cells which contain the cell membrane. The cell membrane is composed of the phospholipids and the protein molecules which provides important properties to the membrane.

The membrane acts as the semi-permeable or selectively permeable membrane as it selects the molecules to be passed through it into and out of the cell.

In the given question, the property of the barrier which may or may not allow the molecules to pass through it is due to the selective nature of the membrane and thus the membrane is selectively membrane.

Thus, Semi-Permeable or selectively permeable is correct.

Answer:

A. Spontaneous Generation

Final answer:

a) Spontaneous generation is the outdated theory that living organisms can arise from non-living matter, which has been replaced by the theories of biogenesis and Cell Theory, affirming that life comes from pre-existing life.

Explanation:

The theory that organisms can arise from inanimate matter is called a) spontaneous generation. This theory, which dates back to ancient Greeks like Aristotle, suggested that living organisms could spontaneously emerge from non-living materials. Flies were thought to arise from rotting flesh, and mice from wheat. However, this theory was disproved by experiments that proved living organisms come from other living organisms, a concept known as biogenesis. The Cell Theory, which is widely accepted today, states that all cells come from pre-existing cells, thus supporting biogenesis over spontaneous generation.

In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for the two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. The F1are intercrossed to produce the F2.
a) What will the phenotypic ratio be in the F2 generation?
b) If an F1 plant is backcrossed with the bitter, yellow spotted parent what phenotypes and proportions are expected in the offspring?
c) If an F1 plant is backcrossed with the sweet, nonspotted parent what phenotypes and proportions are expected in the offspring?

Answers

Answer:

A) 9:3:3:1

B) All bitter fruit, yellow spotted offsprings

C) Phenotypes are bitter yellow spotted (4), bitter no spot (4), sweet yellow spot (4), and sweet no spot (4). 1:1:1:1

Explanation:

This is a typical dihybrid cross involving two genes, one coding for fruit taste and the other for spot color. The allele for bitter taste (B) and yellow spot (S) is dominant over the allele for sweet taste (b) and no spot (s) respectively.

Hence, a heterozygous F1 resulting from a cross between an homozygous dominant (bitter fruit, yellow spot) and homozygous recessive (sweet fruit, no spot) will have a BbSs genotype. The heterozygous F1 offsprings are self-crossed and produce gametes BS, Bs, bS, bs. (See punnet square). The F2 offsprings will have the following phenotypes: Bitter fruit, yellow spot (9)

Bitter fruit, no spot (3)

Sweet fruit, yellow spot (3)

Sweet fruit, no spot (1)

Back cross between a F1 offspring (BbSs) and homozygous dominant parent (BBSS) will produce all bitter fruit, yellow spot offsprings (see attached image). BBSS (4), BBSs (4), BbSS (4), and BbSs (4) are the offsprings' genotypes.

For the back cross between a F1 offspring (BbSs) and a homozygous recessive (bbss) parent, the Phenotypes with their proportions are as follows:

Bitter fruit, yellow spot (BbSs, 4)

Bitter fruit, no spot (Bbss, 4)

Sweet fruit, yellow spot (bbSs, 4)

Sweet fruit, no spot (bbss, 4).

Final answer:

The phenotypic ratio in the F2 generation from crossing two heterozygous watermelon plants (BbSs) is 9:3:3:1. A backcross of an F1 plant with a homozygous bitter, yellow spotted parent results in 100% bitter, spotted offspring. A backcross with a homozygous sweet, non-spotted parent yields a 1:1:1:1 ratio of phenotypes.

Explanation:

In classic Mendelian genetics, the cross between a homozygous bitter fruit, yellow-spotted watermelon plant (BBSS) and a homozygous sweet fruit, non-spotted watermelon plant (bbss) results in the F1 generation all being heterozygous (BbSs) since bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s).

Phenotypic Ratio in the F2 Generation

The intercrossing of the F1 generation (BbSs) would result in the F2 generation having a phenotypic ratio of 9:3:3:1. This is because each characteristic (bitter vs sweet and spotted vs non-spotted) is inherited independently, resulting in four possible phenotype combinations: bitter with spots, bitter without spots, sweet with spots, and sweet without spots.

Backcross with Bitter, Yellow Spotted Parent

If an F1 plant (BbSs) is backcrossed with the bitter, yellow spotted parent (BBSS), the expected phenotypes and proportions in the offspring would be all bitter with spots (100% B-S-), due to the dominance of the bitter and spotted traits.

Backcross with Sweet, Nonspotted Parent

Similarly, if an F1 plant (BbSs) is backcrossed with the sweet, non-spotted parent (bbss), the resulting phenotypes and proportions expected in the offspring would be a 1:1:1:1 ratio. This results from the combination of the F1 heterozygous traits with the recessive sweet, non-spotted parent's traits.

Answers

Answer:

The expected proportion of F2 individuals which are homozygous recessive at both genes is 1/16

All of the F1 generation will have the normal phenotypes for both genes

There will be no homozygous individuals in the F1 generation

Most of the F2 generation will have the normal phenotypes for both genes

Explanation:

A winged hairy male is crossed with a wild type female which is homozygous

Let the allele for vestigial trait be v

allele for wild trait be w

allele for hairy trait be h

Allele for non hairy be n

The genotype of parents would be

vvhh * wwnn

Thus in F1 generation all the offsrping will have  normal phenotypes for both genes

In F2 generation

vwnh * vwnh

Out of 16 offspring only one wil be homozygous recessive i,e

wwnn

Rest all 15 will have normal phenotypes.

Hence, the correct answer is

The expected proportion of F2 individuals which are homozygous recessive at both genes is 1/16

All of the F1 generation will have the normal phenotypes for both genes

There will be no homozygous individuals in the F1 generation

Most of the F2 generation will have the normal phenotypes for both genes

Final answer:

When true-breeding or homozygous individuals that differ for a certain trait are crossed, all of the offspring will be heterozygotes for that trait. If these heterozygous offspring are self-crossed, the resulting F2 offspring will exhibit a ratio of three dominant to one recessive.

Explanation:

When true-breeding or homozygous individuals that differ for a certain trait are crossed, all of the offspring will be heterozygotes for that trait. If the traits are inherited as dominant and recessive, the F1 offspring will all exhibit the same phenotype as the parent homozygous for the dominant trait. If these heterozygous offspring are self-crossed, the resulting F2 offspring will be equally likely to inherit gametes carrying the dominant or recessive trait, giving rise to offspring of which one quarter are homozygous dominant, half are heterozygous, and one quarter are homozygous recessive. Because homozygous dominant and heterozygous individuals are phenotypically identical, the observed traits in the F2 offspring will exhibit a ratio of three dominant to one recessive.

A client is diagnosed with peripheral arterial disease. A review of the client's chart shows an ankle-brachial index (ABI) on the right of 0.45. This indicates that the right foot has which of the following?
a. No arterial insufficiency
b. Very mild arterial insufficiency
c. Moderate to severe arterial insufficiency
d. Tissue loss to that foot

Answers

Answer:

The correct answer is option c.

Explanation:

The ABI or the ankle-brachial index examination refers to a noninvasive and brisk way to determine PAD or peripheral artery disease. The disease takes place when narrowed arteries diminish the flow of blood to the limbs. The condition can result in leg pain at the time of walking and enhances the chances of stroke and heart attack.  

On the basis of ABI, one can find that a healthy individual lacking arterial insufficiency exhibits an ABI of about 10. Those with an ABI of 0.95 to 0.5 shows minor to modest arterial insufficiency. The individuals with an ABI of less than 0.50 exhibits ischemic rest pain. Those with the loss of tissue show extreme ischemia and an ABI of 0.25 or less.
