What factor most affects whether a mutation will be passed to offspring?
ANSWER PLEASEEEEEEE

Answers

Answer 1

Answer:

Mutations are only passed on to offspring when they occur in germ cell DNA, which are the cells that create sperm or ova. ... The mutation will be inherited only if it occurred on a chromosome in either the sperm cell or the ova cell out of many that eventually unite to form a zygote.

They are present in all body cells and can be passed down to new generations. Acquired mutations occur during an individual's life. If an acquired mutation occurs in an egg or sperm cell, it can be passed down to the individual's offspring. Once an acquired mutation is passed down, it is a hereditary mutation

I hope this helps.

How did the peppered moth's environment change, and what caused this change?

Answers

Answer:

Due to the industrial revolution, smoke caused the environment of the peppered moths to change to a darker/black color. This resulted in a higher prevalence of black peppered moths over white peppered moths.

Explanation:

The dark environment made it so black peppered moths had the favorable trait while the white moths, who previously had the advantageous trait due to old environments being light in color, now had a deletirous trait. Predators could now more easily see the light colored moths, so they were more likely to be killed than the dark colored moths, so more dark colored moths were able to reproduce. This lead to a larger prevalence of dark peppered moths.

During the Industrial Revolution, pollution darkened tree trunks in England. This favored dark moths, causing a decline in lighter ones.

What are peppered moths?

The peppered moth's environment changed due to the Industrial Revolution in England during the 19th century. Prior to the Industrial Revolution, the trees in England were predominantly light-colored, and the majority of peppered moths were also light-colored, or "typica." However, as a result of industrial pollution, the bark of the trees darkened, becoming covered in soot and ash.

This created a selective advantage for the dark-colored peppered moths, or "melanics," who were better camouflaged against the darkened trees. The change in the moth's environment was caused by the burning of coal in factories, which released soot and other pollutants into the air, leading to widespread pollution and industrialization. This phenomenon is often cited as an example of natural selection in action, as the moths adapted to their changing environment through the evolution of their coloration.

The gas that Dr. Walter Snelling discovered in 1911 that becomes a liquid under moderate pressure and acts as an energy source is propane.

Properties of Propane

Propane is a gas at room temperature and it was isolated by Dr. Walter Snelling around 1911 in the process of trying to stabilize gasoline.

At cold temperatures or moderate pressure, propane becomes a liquid.

Propane has been and is still being used as an energy source in cooking, powering vehicles, and cutting metals in industrial welding.

In cats, white spots are caused by a dominant allele called T, while (tt) individuals are solid colored. Also short hair(H) is dominant to long hair(h). What would the probability be of getting a white-spotted, long-haired cat from this cross: TTHh x Tthh? What are the phenotypes of the parents?

Answers

Answer:

1. Probability is 1/2

2. Parents phenotypes:

TTHh = white spots, short hair

Tthh = white spots, long hair

Explanation:

This question involves two different genes coding for spot color and hair length in cats respectively. In the first gene, the allele for white spots (T) are dominant over the allele for solid color (t) while the allele for short hair (H) is dominant to long hair (h).

According to this question, a cross between parent cats was performed as follows: TTHh x Tthh. The following gametes will be produced by each parent:

TTHh - TH, Th, TH, Th

Tthh - Th, Th, th, th

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. However, according to the question, 1/2 of the offsprings will probably be white-spotted and long-haired. The phenotypes of the parents are as follows:

TTHh = white spots, short hair

Tthh = white spots, long hair

Which of the following is not true of energy in a cell?

O Energy can be created by the cell.
O The cell uses mostly chemical energy.
O Energy can be converted by the cell.

Answers

Answer:

I think is the top one A hope this helps

Cells have a different function it can convert chemical energy to another form of energy to maintain homeostasis, and cells cannot create energy only change the form of energy, hence option b is correct.

What is the energy of the cell?

Every cell must continue to check its levels of energy and adjust ATP production rates in line with metabolic demand in order to keep homeostasis.

The ability of cells to sense, and convert nutrients into chemical energy is essential for the continuous fulfillment of this energy demand.

To drive metabolic reactions that would not happen automatically, to transfer necessary substances across membranes, and to do mechanical work, such as moving muscles, cells need chemical energy.

Therefore cells use energy to maintain homeostasis and can change one form of energy into another but can not create energy, hence option b is correct.

15. Describe how the structure of the bird respiratory system provides the energy the
bird needs for flight.

Answers

Answer:

The bird's respiratory system consists of paired lungs, which contain static structures with surfaces for gas exchange, and connected air sacs, which expand and contract causing air to move through the static lungs.

Birds do not have a diaphragm; instead, air is moved in and out of the respiratory system through pressure changes in the air sacs. ... Bird lungs do not expand or contract like the lungs of mammals. In mammalian lungs, the exchange of oxygen and carbon dioxide occurs in microscopic sacs in the lungs, called 'alveoli.'

Air sacs are found as tiny sacs off the larger breathing tubes (tracheae) of insects, as extensions of the lungs in birds, and as end organs in the lungs of certain other vertebrates. They serve to increase respiratory efficiency by providing a large surface area for gas exchange.

How do birds respire?

Some birds can sing while they fly! ... When the bird takes a second breath, the air in the lungs is sucked into the cranial air sacs -caudal thoracic, cervical, and clavicular. The cranial air sacs act as a holding chamber which provides a small back flow of air into the lungs during expirations.
