How does a mutation get passed from parent to offspring?

Answers

Answer:

Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.

You learned about the aptly named enzyme Citrate Synthase. There are more enzymes that count citrate as substrate or product. Compare and contrast two reactions below that each split two carbons from citrate to make oxaloacetate. One catalyzed by the enzyme ATP Citrate Lyase and the second catalyzed by Citrate Lyase.

Acetyl-CoA
Citrate → ↑ → Oxaloacetate lyase
CoA-SH → ↑ ↑ ←ATP ↓→ ADP + Pi
ATP Citrate
Acetate
Citrate → ↑ ↓→ Oxaloacetate
Citrate lyase

Which of the following is an accurate statement about why ATP is required by ATP Citrate Lyase?

a) The hydrolysis of the thioester involving CoA-SH helps split ATP into ADP and Pi.
b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.
c) The Acetyl-CoA is pulled rapidly away to make lipids so the reaction needs extra energy to make it fast enough to keep up with demand.
d) The two carbons of acetate are more energetic than those on Acetyl-CoA and therefore don't need ATP to split them from citrate.
e) ATP is required to spit the two carbons from citrate.

Answers

Answer:

b) The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.

Explanation:

In the citrate cycle, we know that lysis is mediated by the hydrolysis of ATP, which is the fuel of the reaction, so the correct answer is B. The hydrolysis of ATP helps "pay for the formation of a thioester involving CoA-SH.

When considering human impacts to ecosystems, identify the incorrect statement:
Select one:
a. cod, swordfish, halibut and mackerel populations are especially vulnerable to collapse
b. coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas
c. aquaculture may provide a sustainable alternative for raising farmed fish to feed a growing human population, allowing ocean fisheries to recover
d. over half of global ocean fisheries populations have become severely overharvested within the past century

Answers

Answer:

coral reefs providing critical habitat and sources of food for tropical fish are slowly recovering, due to successful enforcement of fishing quotas

Explanation:

This is a wrong statement because coral reefs contrary to the statement is not recovering, Over-fishing an destructive fishing,(to meet up with increasing demand) are some of the human impacts  reltively control by  the enforcement.

But,acidification  (eutrophication),  and  mass coral bleaching from global warming  are not restricted by the enforcement  of fishing quotas and  are drastically reducing the population of the reefs.This in turn affecting the survival of the fishes, reducing the population,

Global warming

Explanation:

Global warming is defined as the heating of Earth's surface, atmosphere and oceans due to the result of human activity such as burning of fossil fuels that releases methane, carbon dioxide (CO2),  and other greenhouse gases into the atmosphere.

Global warming is the result of action at one part of the world but it affects the other part of the world where human intervention is zero.

Due to global warming, there is extreme changes in climate which is resulting in melting of glaciers, rise in sea levels and loss of biodiversity.

Hence, the correct answer is Global warming.

What is phenotype?

Phenotype refers to the observable physical and behavioral characteristics of an organism, which are determined by the interaction between its genetic makeup (genotype) and the environment. The phenotype can include traits such as height, eye color, body shape, and even personality traits.

These characteristics are influenced by both genetic and environmental factors, such as exposure to sunlight, diet, and other environmental conditions. In many cases, a single gene may have multiple effects on the phenotype, and many genes may work together to produce a single trait. Phenotypic traits can also be influenced by epigenetic changes, which involve alterations in gene expression without changes to the underlying DNA sequence. Understanding the relationship between phenotype and genotype is crucial for fields such as medicine, agriculture, and genetics.

a. allele frequency


b. gene pool


c. genotype


d. phenotype

Answers

Answer: option D.

Phenotype

Explanation:

Theory of natural selection shows that different organism survive, adapt and reproduce in their environment due to their different phenotypic variation. The phenotypic variation exist among individual organisms and it is heritable which is transfer from one generation to another.

Phenotype are traits or physical characteristics or observable characteristics of organism e.g organisms appearance, behavior e.t.c.

Answer:

d. phenotype

Explanation:

Natural selection exert pressure on the physical characteristics of organisms, that is, the phenotype.

Natural selection refers to the variation in the survival and reproduction of individuals within a population based on how adaptable they are to the environment in which they live.

The forces of natural selection act on the physical characteristics of individuals, that is how physically fit or unfit individuals are. Individuals that posses physical characters that makes them to be better adapted to the environment survives and reproduce better than their counterparts that are less adapted. Natural selection thus selects for the physical characters that make the individuals to be better adapted.

gene1: 0.01
gene2: 0.05

gene 4: 1.01
gene 5: 2.34

Which gene has a dN/dS ratio that provides the strongest evidence of negative (‘purifying’) selection?

Answers

Answer:

The correct option is gene 1 with the dN/dS ratio of 0.01

Explanation:

In order for negative selection to occur, the dN/dS ratio has to be between 0 and 1. There three genes that lie within this range, and hence, we can choose the smallest one to provide the strongest evidence among those to represented as the one being negatively selected. Where the dN/dS ratio is equal to 1, it means neutral and where the dN/dS ratio is greater than 1, it means positive selection.
