Answer:
3. AGG
Explanation:
When doing mRNA, Adenine always pairs with Uracil, but when you have Thymine you pair it with Adenine. But thymine never pairs with Uracil.
so on here, you have UCC and the opposite would be
AGG.
Why are linked traits inconsistent with Mendel's laws?
Answer:
Linked Genes Violate the Law of Independent Assortment. Although all of Mendel's pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other.
Explanation:
PLz, mark me as a brainlist :)
Mendel studied the transmission of genes in peas(pisum sativum) that were placed on different chromosomes. During meiosis there are two types of recombinations that make sure the offspring is different from the parent. First intrachromosomial recombination (crossing-over)where genetic material is exchanged between chromosomes. And interchromosomial recombination when homologous chromosomes are separated.
In Mendel's experiments only interchromosomial recombination was considered, but when Thomas Hunt Morgan experimented with Drosophilla Melanogaster he didn't get the same results because he focused on genes that were placed on the same chromosome. In this situation crossing over influenced the results.
There is a population of 1,000 wolves. Over the course of a year 100 wolves are born.
What is the birth rate?
•0.1 births per individual per year
•10 births per individual per year
•1.0 births per individual per year
•0.01 births per individual per year
Answer:
10
Explanation:
Because 1,000 divided by 100 equals 10.
There is a population of 1,000 wolves. Over the course of a year, 100 wolves are born. The birth rate is 10 births per individual per year. The correct option is b
What is the birth rate?Birth rates of organisms decline and mortality rates increase in density-dependent populations due to numerous factors affecting the rate of reproduction and survival.
When there is a disease, competition, or predation in that organism, it has a higher mortality rate and a lower growth rate. These three factors reduce the birth rate and raise the death rate in an organism's population.
If both the death and birth rates are low, the population will not grow significantly and will remain relatively stable.
1000 / 100 = 10
Therefore, the correct option is b, 10 births per individual per year.

A population of Muscovy ducks contains 13 birds with black masks and 37 birds with red masks. Red masks are the dominant trait. What is the frequency of the black allele? What is the frequency of the red allele? What is the frequency of heterozygotes?
Answer: Black allele has frequency of 0.14.
Red allele has frequency of 0.86.
The frequency of heterozygotes is 0.241
Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:
[tex]p+q=1[/tex]
[tex]p^{2}+2pq+q^{2}=1[/tex]
p represents frequency of dominant allele;
q represents frequency of recessive allele;
2pq is frequency of heterozygotes;
For the frequency of red allele, which is dominant, we can use:
[tex]p^{2}=\frac{37}{13+37}[/tex]
[tex]p^{2}=\frac{37}{50}[/tex]
[tex]p^{2}=0.74[/tex]
[tex]p=\sqrt{0.74}[/tex]
p = 0.86
For the black allele:
[tex]p+q=1[/tex]
[tex]q=1-p[/tex]
[tex]q=1-0.86[/tex]
q = 0.14
Frequency of heterozygotes is
2pq = 2(0.86)(0.14)
2pq = 0.241
Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.

How can the number of channel or carrier proteins present in the membrane affect the rate of transport of substances into the cell?
Answer:
The more protein channel or carrier a cell has, the faster will be the transport of a specific compound. In other side, lower will be the transport of the rest of compounds, such as O2, H2O.
Explanation:
A protein channel or a carrier protein acts as facilitators in the transport of compounds. The compounds who are polar can't pass easily, or can't even pass, trough the plasmatic membrane, because of it's nonpolar center. So, the cell needs to provide a way for the polar compounds who are needed inside or outside of the cell, thus we have the proteins channel or carrier. They form a polar way for the polar compounds pass into or out the cell.
However, the more proteins we have to transport, less space the membrane will have for the others compounds, because every transport protein just acts with a specific compound or others very similar to it.
Which function is shared by the immune and integumentary system ?
- excretion
- movement
- protection
Or - storage
The correct answer is protection because the integumentary system provides protection.
The skin and other parts of the integumentary system work in concert with other organ systems to maintain homeostasis. The skin works with the immune system to protect the body from pathogens by acting as a physical barrier to microorganisms.
Description: This feature is usually called the exoskeleton because it can be the hair of the nail, or basically the inner one that grows naturally on the outside, but in this case, it is not the exoskeleton, It is there to protect.
What are the functions of the integumentary system?The skin has three main functions: protection, regulation, and sensation.
Thus it concludes that the integumentary system has the ability to provide protection.

Which statement BEST summarizes Darwin's explanation for these differences?
A) Random mutations caused the shape of the shells to fluctuate periodically.
B) The shape of the tortoise shell varied because the predators on the islands were all similar.

In the middle of the night, you are awakened by hunger pains. You proceed to get up and go to the kitchen to have a couple of cookies and a glass of milk. Satisfied you go back to bed content. Explain in detail what tissues, organs, and organ systems are involved in completing that task. Be sure to include how the systems interact. The more detail the better! Start with getting up to get the food and include details on the steps in how the food gets digested.
Explain in detail
Answer:
Mouth, stomach, liver, pancreas and small intestine.
Explanation:
If we eat these foods which have carbohydrates, its digestion starts from the mouth because the saliva present in the mouth mixes with the food and start its digestion. When the food reaches to the stomach, the foods are broken down into micromolecules with the help of enzymes secreted by liver and pancreas. After that the food goes to the small intestine where absorption of nutrients and water also occurs.

possible response. There may be more than one correct answer.
Genetic
Infectious
Potentially lethal
Inherited
Answer:
Genetic = yes
Infectious = no
Potentially lethal = yes
Inherited = yes
Explanation:
"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.
It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

if the stomata could not close , would that be a good or bad thing for the plant?
Answer:
Transpiration is the process of evaporation of water from the leaves and stems to the atmosphere. The stomata close when the guard cells shrink, which in turn ceases the transpiration. Opening of stomata allows the process of transpiration, so the root cells do not die.
But if it can't close:
The downside to wide open stomata is increased water loss (transpiration). So stomata of cool-season turf grasses have decisions to make. The plant needs to capture and store energy via photosynthesis, however, excessive water loss through transpiration can result in plant injury or death.
It's a bad thing.
