A)
It is possible to obseve that the fur color of the feline is connected with the male chromosome "X". The presence of Xb (recessive) and XB (dominant) results in the tortoise color.
The ausent tail T is carried in the autosomes with a dominacy over the presence of tail "t" and the presence of both dominances "TT" results in the death of the offspring.
B) Genotypes of the parents:
Male: XbY, Tt
Female: XBXb, Tt
why is it easy for a virus to mutate?
Answer:
Viruses mutate very quickly The major reason that viruses evolve faster than say, mosquitoes or snakes or bed bugs, is because they multiply faster than other organisms. And that means every new individual is an opportunity for new mutations as they make a copy of their genetic material. Many of those mutations have no noticeable effect.

Earth Science
Answer:
here's some thoughts
Explanation:
Glaciers cut through rock and deposit the sediments as they melt.
In Connecticut, Long Island Sound was created by glaciers. Glaciers created a natural barrier between the ocean and the land. Almost like a moat protecting a castle.
There are many large boulders in cities around Connecticut that were left behind after the ice melted away. The Connecticut River Valley was cut by a glacier.

Where would you expect to find the most genetic diversity among humans?(This is a multiple choice question)
A. in city
B. in a town
C. in a family
Answer:
In a city
Explanation:
Your family all shares DNA, and towns are small and have fewer people and the lack of people leads to a lack of diversity.
What are details/evidence of a Prokaryotes? please help and thank you.
Answer:
Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide. Prokaryotes often have appendages (protrusions) on their surface.

Which of the following best explains how the fossil record provides evidence that evolution has occurred?
a. It shows that forms of life existed on Earth at least 3.5 billion years ago.
b. It shows the detail of structural and behavioral adaptations of organisms.
c. It shows how the embryos of many different vertebrate species are very similar.
d. It shows that the structure of groups of organisms have progressively changed over time.
Answer:
A It shows that forms of life existed on Earth at least 3.5 billion years ago.
Explanation:
AIt indicates that forms of life existed on Earth at least 3.5 billion years ago. It indicates the exact cause of structural and behavioral adaptations of organisms.
A new study in the Proceedings of the National Academy of Sciences that uses the latest techniques to date the most aged remains available, confirming the existence of bacteria and microbes nearly 3.5 billion years ago, possibly living on a planet without oxygen.

Explanation:
choose a plant or animal that you think is interesting. describe some of the threats or challenges
Answer:
If I were to choose a plant or animal which is interesting, I'd choose the "cactus."
Explanation:
A "cactus" is truly a splendid plant owing to its ability to survive in the desert or periods of drought. Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.
One of these threats is the "over-collection of cacti." Due to its versatile use, the cactus is often sold as an ornamental plant. Another threat is the number of pests, such as snails and slugs, that attacks it yearly. It is a delicious food for mealy bugs, red spider mites, gnats, flies, etc.People often misunderstand the cactus' water level needs. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.Water Hyacinth
Water Hyacinth grows profusely, forming dense mats that can spread across water surfaces eventually blocking the entire water body.
It can eliminate native wetlands and waterways and kill aboriginal fish and other wildlife.
Also, it causes a high evaporation rate and loss of water and degrades water quality.
What are the natural predators of the water hyacinth?
Water hyacinth is native to South America, the only continent where natural predators such as weevils and moths keep it at bay.
Thus, these are some of the threats or challenges of water hyacinth.

What controls the ratio of the two isotopes in foraminifera shells?
A. The temperature of the water
B. The salts in the water
C. Water pressure
D. Radiation
Answer:
A. the temp of the water
Explanation:
a sediment core from the JOIDES Resolution, an ocean-going ship that has collected many sediment cores that record Earth’s past climate.
The ratio of the two isotopes in foraminifera shells is affected by temperature.
What is temperature?Temperature is the degree of coldness or hotness of an object or a particular place.
Isotopes are atoms of the same element with different masses.
The factors affecting the ratio of isotopes of elements depends on the Half-Life of the isotopes as well as temperature.
Temperature will make the rate of decomposition reaction faster.

Explanation:
what are the limitations of the cell theory?
Answer:
Viruses are a limitation to cell theory
Explanation:
According to cell theory, all cells arise from pre - existing cells. But viruses lack any membranes and do not show the characteristics of life unless they enter a living body and use its cell machinery to multiply.
