Fatty acids from ols present in fish Diet adequate in synthetic form of folate Diot rich in fiber Diot low in sodium and high in potassium Reduced risk of neural tube Reduced risk of hypertension Reduced risk of defects and stroko cardiovascular disease Roduced risk of some types of cancer
Answer:
Reduced risk of neural tube defects- diet adequate in synthetic form of folate Reduced risk of hypertension and stroke- diet low in sodium and high in potassium Reduced risk of cardiovascular disease- fatty acids from oils present in fish Reduced risk of some types of cancer- diet rich in fiberExplanation:
As you may already know, the adequate intake of certain nutrients is very beneficial to our body and to improve and maintain our health. That's because these nutrients act in the construction of essential molecules to keep our body functioning in a healthy and adequate way. Among the numerous nutrients necessary for our health, we can mention that the adequate intake of folate has the ability to reduce the creation of possible defects in the neural tube, while a diet rich in potassium can reduce the risks of hypertension, especially if accompanied by a low sodium diet. Following this same reasoning, a diet rich in fiber can reduce the risk of cancer, in addition to promoting good bowel function. Last but not least, a diet rich in fatty acids from fish can reduce cardiovascular disease.

For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to label the nitrogen of the DNA, rather than the phosphate. They reasoned that each nucleotide has only one phosphate and two to five nitrogens. Thus, labeling the nitrogens would provide a stronger signal than labeling the phosphates. Why won't this experiment work?
A) There is no radioactive isotope of nitrogen.
B) Radioactive nitrogen has a half-life of 100,000 years, and the material would be too dangerous for too long.
C) Avery, MacCloud and McCarty already did this.
D) Although their are more nitrogens in a nucletotide, labeled phosphates actually have 16 extra neutrons; t Shift Ctrl herefore, they are more radioactive.
E) Amino acids (and thus and proteins proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA.
Match the scientist(s) with his/her/their contributions.
A. Watson and Crick
B. Friedrich Miescher
C. Hershey and Chase
D. Friedrick Sanger
E. Rosalind Franklin
F. Linus Pauling
G. Avery, MacCloud and McCarty
Answer: E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
The Hershey-Chase experiment, is an experiment that demonstrated that the genetic material of phage isn't protein but rather it's DNA.
Based on the information given in the question, the experiment will not work because amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Therefore, the correct option is E.

6-48 In somatic cells, if a base is mismatched in one new daughter strand during DNA replication, and is not repaired, what fraction of the DNA duplexes will have a permanent change in the DNA sequence after the second round of DNA replication
Answer:
1/4
Explanation:
DNA replication is semi-conservative, which means that during this process one DNA strand will be from the original DNA template, whereas the other DNA strand will be newly synthesized. In the first round of DNA replication, daughter cells receive a DNA molecule containing one original DNA strand and one newly-synthesized DNA strand (in this case, one of these daughter cells will contain a mismatch). If the mismatch is not repaired, then in the second round of replication the DNA molecule containing the mismatch would separate during replication, and the DNA strand containing the erroneous nucleotide will serve as a template for the synthesis of a new DNA molecule, thereby producing a permanent mutation.

The number of ducks in a pond is equal to the square root of the number of fish, and the number of turtles is equal to the cube root of the number of fish. The number of fish in the pond is more than 1 but less than 100. There are no fractional or negative numbers of ducks, fish, or turtles.
Answer:
There are 64 fish, 8 ducks and 4 turtles.
Explanation:
From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.

Many genotypic and phenotypic characteristics are linked to the X chromosome. Some of these are caused by X-linked traits, whereas others are due to X chromosome inactivation. Drag the labels on the left to the appropriate category on the right.
Calico cats have patches of black and orange fur X inactivation X-linked Color blindness is more common in men "Heterozygotes" can express the recessive phenotype Hemophilia Rett syndrome is not always fatal in females Barr bodies
Answer:
X chromosome inactivation:
- Calico cats have patches of black and orange fur
- "Heterozygotes" can express the recessive phenotype
- Rett syndrome is not always fatal in females
- Barr bodies
X linked traits:
- Color blindness is more common in men
- Hemophilia
Explanation:
X chromosome inactivation refers to the mechanism in which one X chromosome is randomly inactivated during early embryonic development in female mammals. The inactivated (silenced) X chromosome is condensed into a structure called Barr body. In cats, the gene encoding for the orange/non-orange fur coloring is X-linked, thereby X inactivation explains why most calico cats (i.e., those cats that have a color pattern with orange and black spots) are female. Moreover, Rett syndrome is a neurodevelopmental disorder caused by a mutation in the X-linked MECP2 gene, and therefore this disorder is much more serious in males. On the other hand, color blindness is more common in men because males have only one X chromosome. In the same way, hemophilia, which is a disorder caused due by a mutation in one gene required for synthesizing one clotting factor, is more common in males than in females because the gene responsible for this disorder is located on the X chromosome.
