Using the model, describe the structure of DNA in terms of nucleotides, covalent bonds, sugars, phosphates, bases, and hydrogen bondsExplain the importance of the hydrogen bonds to the function of a DNA molecule.

Answers

Answer 1

Answer:

The importance of the hydrogen bonds to the function of a DNA molecule as it holds the complementary strands and is responsible for its structure.

Hydrogen bonds in DNA

DNA has a double-helix structure. It has two antiparallel strands. Both strands have a sequence of nitrogenous bases that are linked together by hydrogen bonds.

The hydrogen bond holds together the base pairs in the middle. Adenine is always bound with thymine and guanine to cytosine in DNA by hydrogen bonds. In absence of hydrogen bonds, DNA would have to exist as a different structure, not a double helix.

Answer 2

Answer:

Answer:

DNA has a double-helix structure because hydrogen bonds hold together the base pairs in the middle. Without hydrogen bonds, DNA would have to exist as a different structure. he major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.

Answers

Each statement is scientific because the reasons to which they pertain are of scientific nature. their reasons might appear to be general but they are specific and based on logic. a kid is afraid of the ghosts because the ghost represents the ability to do un-natural things. a mouse needs to be black to be able to feed in the dark. similarly there are scientific explanations for the questions.

Answer: question 3

Explanation:

Which explanation is most likely the reason for the evolution of a larger brain in humans?The size of the human brain increases the more it is used.
A larger brain allows humans to solve complex problems.
The size of the human brain has changed randomly over time due to mutations.
A large brain increases humans’ ability to fight and survive disease.

Answers

The most likely reason for the evolution of a larger brain in humans is that the size of the human brain increases the more it is used. The correct option is A. Evolution findings show that as the activities of man increase and as he advance in using his brain to develop new things that are needed for his convenience, the brain size also continues to increase.

Answer:

A large brain allows humans to solve complex problems.

Explanation:

The large brain in humans has enabled them to solve a complex problem in of the real world and also enabled them to survive more as compared to humans with the smaller brains.

In seven million years the size of the human brain is tripled. That allows them to store and process a huge amount of information and also help to interact with the people in the surrounding better.

Hence, the correct answer would be option B.

In ΔABC, if the lengths of sides a and c are 8 centimeters and 16 centimeters, respectively, and the measure of ∠C is 35°, what is the measure of ∠A to two decimal places?a. 16.67°

b.17.50°

c.26.57°

d.35.53°

Answers

From sin theorem we know that:

sin(A)/a = sin(C)/c, so sin(A) = asin(C)/c = sin(35deg)/2. So A = arcsin(sin(35deg)/2) = 16.67.

The answer to your question is A. I hope that this is the answer that you were looking for and it has helped you.

16. Which of the following phase changes absorbs heat energy?A. Condensation
B. Vaporization
C. Deposition
D. Freezing

Answers

The correct answer is option B, that is, vaporization.

The change of phase is similar to the change of state. When a component changes from one phase or state into another one can say that it has gone through a change of phase, like water evaporating and becoming water vapor.

The changes of phase always take place with a change of heat. Heat in the process either comes into the substance or comes out of the substance at the time of change of phase, and in the process of vaporization heat is absorbed by the liquid as it vaporizes.

The answer is Vaporation

What kind of air masses form over land? Maritime air mass Polar air mass Continental air mass Tropical air mass

Answers

The correct answers are:

- Polar air mass;

- Continental air mass;

The polar air masses form predominantly over land, or rather ice. They form over the poles and their close proximity, with the ones forming on the south pole being formed directly over Antarctica as a land mass, while the ones on the north pole being formed over ice, or rather the frozen ocean. They are very cold and very dry air masses.

The continental air masses form above land, deeper into the mainlands of the continents, which is why that have this name. They can be either very cold and dry in winter, or very hot and dry in the summer.

Answer:

Continental air mass
