3 bases make up the code for amino acids
Answer:
d
Explanation:
When considering the frequency of the potential alleles of a gene in a population, the total must add up to 1. Think of it like percentages. an allele frequency of 0.3 means 30% of the population carry it (out of a possible 100%).
We know that the frequency of c1 is 0.3. Lets take each option and see if it can be true
a) cannot be less than 0.3. - false. It <em>could </em>be less than 0.3. For example, it could be 0.1, meaning the frequency of allele c3 would be 0.6 (because 0.3 + 0.1 + 0.6 = 1)
b) cannot be greater than 0.3. - false. It <em>could </em>be greater than 0.3. For example, it could be 0.5, meaning the frequency of allele c3 would have to be 0.2 (because 0.3 + 0.5 + 0.2 = 1)
c) is 0.7. - false. It <em>can't </em>be 0.7, because that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)
d) cannot be greater than 0.7. - true. It <em>cannot </em>be greater than 0.7, because that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)
The correct answer is option (C) Gray rabbits would be eliminated by predators.
Camouflage is an adaptation by organisms allowing them to blend with the environment. This helps them in surviving or escaping from their predators. It can be throught coloration or developing a particular pattern or mimicry.
The example given above is a type of camouflage through concealing coloration. Concealing coloration includes having a fixed camouflage and changing the camouflage depending on the environment. Grey rabbits cannot exhibit camouflage as the backgroud is dark rocks and light stones. As a result, these rabbits are clearly visible to the predators and get elimiated by them.
Answer: The number of adenines in one strand is equal to the number of thymines in the complemetary strand.
Explanation:
Deoxyribonucleic acid or DNA is a molecule that contains the genetic information in all living organisms. So it contains all the hereditary genetic information that has the instructions to development. This DNA molecule consists of two strands that bond together to form a double helix structure. <u>Each strand of DNA is made up of nucleotides which are basic chemical components made of a phosphate group, a sugar group and one of four types of alternative nitrogenous bases</u>. The four types of nitrogenous bases found in the nucleotides are:
- Adenine (A)
- Thymine (T)
- Guanine (G)
- Cytosine (C).
<u>The sequence of these bases determines how genes are made, and each gene has different biological instructions to create proteins (that will have different functions in the organism).</u> To form a DNA strand, the nucleotides are linked together in chains, alternating with the phosphate and sugar groups.
The nitrogenous bases are complementary between them. Adenine and thymine are complementary, as are guanine and cytosine. So since adenine is complementary to thymines, and cytosine is complementary to guanine, the number of adenines in one strand is equal to the number of thymines in the complemetary strand. And the number of cytosine is equal to the number of guanine.
<h3><u>Answer;</u></h3>
The water that covers over 70% of the Earth's surface stabilizes the weather and climate of the Earth.
<h3><u>Explanation</u>;</h3>
- Specific heat is a measure of the amount heat energy that is required to increase the temperature of a substance by a certain temperature interval.
- If a substance has a high specific heat, it requires a large input of heat energy to increase the temperature of the substance.
- <em><u>Water can absorb a large amount of energy while producing only small changes in temperature because water has a high specific heat. This property of water is very important to the organisms on Earth because the water that covers over 70% of the Earth's surface stabilizes the weather and climate of the Earth. </u></em>
- <em><u>This creates a temperature range that is stable enough for diverse living organisms to live and grow on Earth.</u></em>
