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?
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

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

Question: 1.11
Originally, two species of finches lived in the Maldives. One species had long, narrow books for capturing insects from within troes. The other species had larger thicker books for cracking soods. Following an increase in
logging, this ecosystem's population of finches with narrow books began to decline
How does this event support the theory of evolution?
It supports the idea of a common ancestor
Oltillustrates the principle of natural selection
It provides an example of behavioral isolation
It demonstrates analogous structures and evolution
Answer:
I'm thinking maybe B, illustrates the principle of natural selection.
Explanation:
This example shows that, once a particular event happens in a species' ecosystem that negatively affects their lifestyle, natural selection occurs and kills off those with a disadvantageous adaptation (in this case the narrow-beaked finches, since they could no longer eat insects but did not have the beak size to crack seeds), allowing those with the advantageous adaptation (in this case, the thicker-beaked birds) to prosper.
Answer:
It illustrates the principle of natural selection.
Explanation:
for natural selcection to occur things will change just how the was the finches caught and ate their food

Which of the following is not true of energy in a cell?
The cell must have energy to maintain homeostasis.
O Energy can be created by the cell.
O The cell uses mostly chemical energy.
O Energy can be converted by the cell.
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.

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