4. Watson and Crick made a successful model of DNA based on
Rosalind Franklin's X-ray studies. This indicated that
DNA was
A. a triple helix with intertwined bases.
B. a double helix with bases outside the helix.
a. a double helix with bases inside the helix.
D. a single linear molecule of bases held together by
sugar-phosphate bonds.
Answer:
The right answer is the third statement.
--> A double helix with bases inside the helix.
This indicated that DNA was a double helix, with bases inside the helix. The correct option is c.
What is Watson and Crick's DNA model?Watson and Crick theorized that DNA is a double helix made up of two long helical strands twisted together.
In "Genetic Implications," Watson and Crick postulate that the replication of deoxyribonucleic acid, or DNA, may have a structural foundation. Scientists had just recently concluded that DNA contained genes, which were known to contain information that dictated an organism's identity when Watson and Crick proposed their theory of DNA replication.
In their model, each DNA strand was made up of discrete elements called bases, and the bases on one DNA strand matched the bases on the other.
Therefore, the correct option is c. a double helix with bases inside the helix.

If thyroid hormones are not released, you can regulate body temperature by _____, which requires a greater use of _____.
Answer: shivering; oxygen
Explanation:
The thyroid hormones are produced by the thyroid glands and they're the triiodothyronine and the thyroxine. The thyroid hormones are required in metabolism regulation, performs digestive functions, controls the muscle of the heart, and develops the brain.
If thyroid hormones are not released, you can regulate body temperature by shivering and which requires a greater use of oxygen.

In 1956 Tijo and Levan first successfully counted human chromosomes. The reason it would have taken so manyyears to have done so would have included all but which of the following?
a. Watson and Crick's structure of DNA was not done until 1953.
b. Chromosomes were piled up on top of one another in the nucleus.
c. Chromosomes were not distinguishable during interphase.
d. A method had not yet been devised to halt mitosis at metaphase.
Answer:
A
Explanation:
The correct answer would be that Watson and Crick's structure of DNA was not done until 1953.
The fact that chromosomes are condensed together in the nucleus, are not distinguishable during interphase, and a method had not yet been devised to halt mitosis at metaphase could have plausibly delayed the successful counting of human chromosomes.
On the other hand, the discovery of the structure of the DNA could not have delayed the study of chromosomes because the DNA structure has no bearing on the karyotyping of chromosomes.
The chromosomes of organisms are best studied using a relevant microscope during metaphase when they would have fully decondensed and align at the equator of the cell or the metaphase plate. At the interphase phase of the cell cycle, chromosomes are full condensed under the view of the microscope.
The correct option is, therefore, A.

Mistakes are sometimes made in duplicating or transmitting genetic information. These mistakes are called
Answer:
Mutation
Explanation:
Mutation is any alteration or change in the genetic sequence of a gene caused by mutagens (substances) or mistakes during replication of genetic sequences.
A mutation occurs in the gene from time to time, although, the cell has protocols in place to put them under control if they occur. However, when DNA or a gene is being copied and transferred to offsprings, there is bound for mistakes called MUTATION to occur.

A male and a female are both heterozygous for a particular trait. Which of the following represents the expected ratio of dominant to recessive phenotypes in the offspring?
The given question is incomplete as it lack the options, however, answer can be given by the provided information.
Answer:
The correct answer is - 3:1 ratio.
Explanation:
In the question it is given that both male and female both are heterozygous for the trait, let assume dominant allele A and recessive allele a so the the gene for the both male and female is Aa.
Punnett square for the cross between both:
gametes: A, a and A, a.
A a
A AA Aa
a Aa aa
here two out of four are heterozygous dominant and one is dominant and one is recessive.
thus, 3 out of 4 are dominant and one out 4 are recessive.
thus, the answer is 3:1 ratio

20. Which equation represents the formation of water?
21. Which equation represents the formation of an acid solution?
22. How many atoms of oxygen (O) are on both sides of equation
23. How many atoms of hydrogen (H) are on both sides of equation
24. How many atoms of hydrogen (H) are on both sides of equation
25. In which equation are carbonic acid molecules broken apart into
hydrogen ions and bicarbonate ions?
Answer: 20. A 21. B 22. A=2, B=3 23. A=4, B=3 25. B
Explanation: A has H2O (water). B has a hydrogen ion, so acidic.
In B H2CO3 is carbonic acid
The loss of hydrogen atoms leads to the formation of acids and the hydroxide forms bases. Equation A represents the formation of water, and equation B shows the acidic solution.
What is a chemical reaction?Chemical reactions are said to be involved in producing products from the reactants that undergo chemical changes. Water is formed by reacting the four hydrogens and one oxygen molecule as:
2H₂ + O₂ → 2H₂O
Equation B represents the formation of the acid as hydrogen ions are released along the product. The proton donation (hydrogen ion) is the characteristic property of the acids.There are 2 oxygen atoms in equation A, and 3 atoms of oxygen in equation B.There are 4 hydrogen atoms in equation A and 2 atoms of hydrogen in equation B.In equation B, carbonic acid breaks to form hydrogen ions and bicarbonate ions as:H₂CO₃ → H⁺ + HCO₃
Here, carbonic acid dissociates a proton that makes the solution acidic.
Therefore, the first equation represents the formation of water by oxygen and hydrogen atoms.

1.How does Nitrogen cycle through the enviroment?
2. Trace the steps that carbon cycles from plants,animal,and enviorment?
Answer: 1. The nitrogen cycle is a biogeochemical cycle.
2. The carbon cycle is a biogeochemical cycle.
Explanation:
1. The nitrogen cycle can be defined as the biogeochemical cycle in which the atmospheric nitrogen is utilized by the plants which is fixed by the soil bacteria. The nitrogen becomes the part of the biosphere as plants utilize it as an important development mineral. The nitrogen cycle involves the nitrogen fixation in which plants fix nitrogen by the help of bacteria into ammonia, nitrification in which the ammonia is converted into nitrite, nitrogen assimilation in which the plants assimilate and utilize the nitrogen for their growth and development, and denitrification involves the reduction of nitrite into atmospheric nitrogen. The conversion of nitrogen is carried out via physical and biological processes.
2. The carbon cycle involves the atmospheric carbon dioxide being circulated in plants as they utilize it for photosynthesis. The carbon dioxide is fixed by the plants in the form of carbohydrate which is consumed by the animals and on decomposition of plants and animals dead matter release carbon dioxide gas to the atmosphere. This allows the recycling of the carbon dioxide gas in the environment.
