Answer and Explanation:
There are three phenotypes, so it seems that this an example of incomplete dominance, with the short tail being the intermediate form between long-tail and no-tail. Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Dominant alleles cannot completely cover up the recessive alleles. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one, which would appear if this would be the case of complete dominance.
Available data:
Two short-tailed Manx cats are bred together. F1: 3 kittens with long tails, 5 short tails, and 2 without tails.The T gene might express the tail trait. T allele expresses long the tail and is dominant over t allele which expresses the absence of the tail.
So, homozygous dominant individuals, TT, are long-tailed animals
homozygous recessive individuals, tt, have no tail
Heterozygous individuals, Tt, are short-tailed animals, the intermediate form.
Cross: Two short-tailed Manx cats are bred together
Parental) Tt x Tt
Gametes) T t T t
Punnet Square) T t
T TT Tt
t Tt tt
F1) 1/4 TT = Long-tailed animals
2/4=1/2 Tt = Short-tailed animals
1/4 tt = untailed animals
The ratio 3:5:2 of the progeny in the example is close enough to the Mendelian ratio 1:2:1.
Answer:
This is a case of incomplete dominance. Consider the genotypes below:
LL - long tailed
Ll - short tailed
ll - no tail
The parent genotype is Ll. This means they have the ability to produce offspring with either of the 3 given phenotypes depending on the combination of alleles that get passed down. The cross would be the following way:
L l
L LL Ll
l Ll ll
There's a 25% chance of long-tail, 50% chance of short-tail and 25% chance of no-tail.

1. One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic
information is passed among those types of molecules. Include the results of the processes of
transcription and translation
Answer:
Transcription uses a strand of DNA as a template to build a molecule called RNA. The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein building machines.

A skateboard manufacturing company has had problems with the wheels on its skateboards cracking and causing injuries. An engineer for the company knows of a material that he thinks will make the skateboards safer. What would be the best step for the engineer to take next?
He should publish a report about the innovation and its impact on public safety.
He should conduct tests using computer models to determine the safety impact.
He should immediately begin producing all skateboards with the new material.
He should convert production of half of the skateboards to use the new material.
Answer:
He should conduct tests using computer models to determine the safety impact.
Explanation:
The other ones either use the material without testing it to make sure it is safe first or publish a report without knowing it's impact on public safety

Recombinant DNA technology is possible because all organisms
O A. rely on ribosomes to assemble proteins
B. have some of the same genes
C. use the same codes for amino acids
D. replicate DNA before cell division
Recombinant DNA is possible because all organisms use the same codes for amino acids. Option C is the correct one.
The genetic codesOne of the fundamental characteristics of the genetic codes is that they are similar in all living organisms.
Each genetic code is translated into an amino acid. Thus, living organisms use the same codes for their amino acids in the proteins.
This makes inserting the genes of one organism into the genome of another (recombinant DNA) very easy.

how the water molecules will move.
3. A. How is active
transport different from passive transport?
3. B. What are transport proteins?
3. C. Explain why transport proteins
require energy to function in active
transport.
Answer:
1. Water(solvent) molecules travel from A across the cell membrane / semi permeable membrane to B until the concentrations of A and B become equal.2. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.3. A transport protein is a protein that serves the function of moving other materials within an organism.
4. Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. ... transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.

It may be harmful when people compete to see who can hold their
breath the longest under water. Without oxygen, brain cells
Answer:
tend to not get enough oxygen which may lead to severe brain damage and our brains can get Celebral Hypoxia which includes symptoms such as confusion and loss of coordination
Explanation:
When the brain cells receive less oxygen as required by the brain ; The brain suffers a severe damage due to brain hypoxia.
When one holds his/her breath under water the amount of oxygen flowing into the brain cells is cut off and if the oxygen supply is not restored within 5 minutes, the brain cells will start dying off which will result to severe brain damage and eventual death .
Hence we can conclude that When the brain cells receive less oxygen as required by the brain ; The brain suffers a severe damage due to brain hypoxia .

What is a Population?A population is any kind of complete group with at least one characteristic in common between different species. Populations are not just people or organisms. But, the populations may consist of, however are not limited to, people, animals, businesses, buildings, motor vehicles, farms, objects, or events.
Population data contains various types of influential details such as birth, death, demographic information such as the age, sex, annual income, occupation, language of the species in an ecosystem.

How does the experiment contribute to our understanding of altruism in different creatures?
Answer:
TWO YEARS AGO, a group of Ugandan chimps provided a blow to the idea that humans are the only animals that truly behave selflessly to one another. These chimps showed clear signs of true selflessness, helping both human handlers and other unrelated chimps with no desire for reward.
The question of why we help each other, instead of looking out for ourselves, is one of the most compelling in modern biology. Evolutionary and game theory alike predict that selfish behaviour should be the rule with altruism the exception, and animal experiments have largely supported this idea. Nature, ‘red in tooth and claw’, is painted as a fierce competition between selfish individuals and their even more selfish genes. In this stark landscape, true altruism is apparently a rare quality and some scientists believe that it’s one

Since plastic doesn't biodegrade in the oceans, what does the future hold? What can be done to make the future better?
Answer:
We need to take out the plastic and recycle
Explanation:
The future is scary if we don't act upon our actions. There are many people trying to restore the oceans and providing options for the average person. Some time ago I saw an advertisement for a search engine that if you use it they will take away plastic from the ocean. It was called OceanHero but there are others that do the same thing, such as: Okeano..etc. But another way is to prevent plastic from going into the ocean in the first place by limiting use of single use plastics and setting nets on pipes that lead to rivers to catch stray micro plastics. Another good idea is to ensure that we are not littering and following recycling rules. If we fail to save what we have left, ocean animals may only exist as skeletons and images in a museum.
Hope this Helps!
As plastic is not biodegradable it need to take out the plastic from oceans , other areas and recycle
what is biodegradable substance ?biodegradable substance is defined as the substance which has been generated from microorganisms like bacteria which can be broken down into the simplest compounds or components.
plastics are typically made as non-biodegradable substances as They can’t be broken down by natural method; it will persist in the environment for at least five hundred years and it can take up to one thousand years before plastic breaks down suggested by some scientist.
One of the way to prevent plastic from going into the ocean in the first place by limiting use of single use plastics and setting nets on pipes to catch stray micro plastics.
