If the parent genotypes are Aa and Aa, the offspring are expected to be _____. 1/2 AA and 1/2 aa all Aa 1/4 AA, 1/2 Aa, 1/4 aa 3/4 AA and 1/4 aa

Answers

Answer 1
Answer: Punnet squares are your friend with these kinds of questions :)

      A  |  a  |
A | AA | Aa |
a | Aa | aa |

Now we can easily see that 1/4 of the offspring will be AA, 1/2 will be Aa, and 1/4 will be aa. Therefore, it is the third answer that's correct (1/4 AA, 1/2 Aa, 1/4 aa). Hope this helps! :)
Answer 2
Answer:

Answer:

1/4 AA, 1/2 Aa, 1/4 aa

b. activity level
c. health status
d. genetic makeup

Answers

Answer:

Activity level.

Explanation:

Metabolism is the important for the cell survival and its growth. Most of the metabolic factors does not depend upon the control of the organism and occurs itself in the body.

Some factors can be improved or controlled by the activity level. The activity level can be controlled by the individual and may affect the flexibility and may also affect the other metabolic factor. One can control its own activity level.

Thus, the correct answer is option (b).

The metabolic factor that you have the most control over is B. Activity level.

A circular molecule of dna devoid of any histone proteins describes the chromosome of:

Answers

A circular molecule of dna devoid of any histone proteins describes the chromosome of bacteria.

What is circular DNA?

Circular DNA molecules known as extrachromosomal circular DNA (eccDNA) are thought to exist widely in nature and are unrelated to traditional chromosomes.

Double-stranded circular DNA known as extrachromosomal circular DNA (eccDNA) is produced independently of chromosomes. Although it is widespread in eukaryotes, its count, length, and origin are highly heterogeneous.

DNA has been shown to play a role in the maintenance of telomeres and rDNA, aging, drug resistance, cancer, and phenotypic variation in both plants and animals. Here, we summarize the present understanding of eccDNA's classification, biosynthesis, identification, and functions.

Therefore, A circular molecule of dna devoid of any histone proteins describes the chromosome of bacteria.

Five different students in Mr. Garcia's class have done an experiment once, and each one got similar results. What should the students do to increase the validity of their results? A. Each student should do a few more experimental trials.
B. The students should ask Mr. Garcia for a different experiment to do.
C. The students should compare their procedures and try to revise them.
D. Each student should modify the experiment and see what results they get.

Answers

To increase the validity of the results, all the students of Mr. Gracia's class must perform a few more experimental trials.

Answer: Option A

Explanation:

While dealing with the scientific analysis, one must always commit number of experiments to gain the most accurate and valid result. By doing number of trials, we get different approximate values that can be used to estimate the average result.

This average will be the nearest value of the exact answer if we add more and more number of experiments or trials. Since, the results are similar for each student in the class, they all should attempt more trials or experiments to get the most accurate result.

Answers

Answer:

Explanation:

Chromosomes reders to the DNA and the different proteins associated with it. Humans have 23 pairs of chromosomes, out of which 22 pairs are autosomes and one pair belong to the sex chromosomes.

The homologous chromosome refer to the one pairs of chromosomes that have same physical composition and looks exactly like each other. The pair includes the chromosome from the paternal and maternal origin. The ploidy level refers to the set of chromosome of an individual. The individual can be monoploid, diplod, triploid refers to the one set, two set and three set of chromosomes.

Thus, the answer is homologous chromosome and ploidy number.

Leaf vein patterns in monocot flowering plants are parallel.

TRUE
or
FALSE

Answers

Answer:

The given statement is true.

Explanation:

Monocot plants leaves have different kind of venation to dicot plants. All plant Leaf veins are arranged in a reticulate arrangement or in a parallel through the length of the leaf throughout the leaf.

In most of the monocot flowering species, monocot leaves have parallel venation arrangement while dicots have reticulate venation.

Parallel venation is an evolved adaptive feature of monocots over dicots as it provides the benefit of transportation to the end of the leaves.

Thus, the statement is true.

True. monocots veins run parallel
