what is embryogenesis???
Answer:
Embryogenesis is the development of an animal or plant embryo.
OR
Embryogenesis is the process of development of an embryo from zygote. In embryogenesis, the zygote undergoes repeated cell division through mitosis. The divisions help in the growth of an embryo. Cells undergo differentiation attaining specific shape, size and function. Cell differentiation occurs at specific location resulting in the production of different tissue, organs and organ system.

The surprisingly low rates of genetic differences between different current human populations (about only 6.5%) and that most genetic diversity occurs person-to-person within a population rather than population to population points to:
A.
a common origin of Homosapiens sapiens in Africa from a small number of people
B.
a fairly high rate of gene flow between human populations
C.
a fairly short time, perhaps 200,000 years existing as a new species in Africa
D.
all of the above
Answer:
the answer for this question would be B.
a fairly high rate of gene flow between human populations
Genetic diversity is the result of heritable traits that vary within species. It is seen more in person-person than in population because the human population has a high rate of gene flow. Thus, option B is correct.
What are gene flow and drift?Gene flow is the passing of the heritable traits outside and inside the population due to factors like migration or because of the gametes. The alleles possessing the characters are moved from one population to another.
In genetic drift, the allele frequency experiences an alteration in the genetic pool of the population. High genetic flow and the drift in humans result in genetic diversity. It causes very neutral differences to appear and are most likely to be seen in person rather than in the whole population.
Therefore, the high gene flow results in genetic diversity in the person.

https://brainly.com/app/profile/13253466/answersWhat is the maximum height the hill could be
Answer:
below 1,000 feet
Explanation:
On a map, a hill is represented by contour lines that form concentric rings. The hilltop is located inside the smallest closed circle. An area of high terrain is referred to as a hill, which is often less steep and more rounded than a mountain.
What maximum height the hill could be?A hill can only have an elevation that is one higher than the value that would have indicated the following contour line. That is to say, despite the fact that the next contour line is not visible, the maximum elevation of the hill is actually close below its value.
Any point's elevation can be calculated by locating the closest labeled line, counting the lines above or below it, multiplying that number by the contour interval, and then adding or subtracting the result from the closest contour line.
Therefore, The contour lines are incredibly close together on a steep slope.

Why do allele frequencies give us genetic variation
Answer:
why are The more variation a population has, the better its ability to adapt to changes in its environment through natural selection. If there is more variation, the odds are better that there will be some alleles already present that allow organisms to survive and reproduce effectively under the new conditions
Explanation:
In eukaryotes transcription takes place in the _________. translation takes place in the ________.
1. cytoplasm/cytoplasm
2. nucleus/cytoplasm
3. nucleus/ribosomes
4. ribosomes/nucleus
Answer:
3
Explanation:
The correct answer will be option-Transcription takes place in the nucleus, and translation takes place in ribosomes.
The regulation of genes is regulated and controlled by two main processes of central dogma called transcription and translation.
Transcription is the process of formation of messenger RNA or mRNA from a single strand of DNA whereas translation is the formation of protein from mRNA.
This process takes place in different sites in prokaryotes and eukaryotes. In prokaryotes, both transcription and translation take place in the cytoplasm but in eukaryotes, the transcription takes place in the nucleus whereas translation takes place in the ribosomes present in the cytoplasm.
Thus, the selected option is the correct answer.

name one way mutations can be beneficial?
They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time.

P=purple flowers and p = white flowers. What phenotype will a
heterozygous plant show? *
Answer: They will be Purple as their genotype will be Pp
Explanation:
A conditional mutation expresses its mutant phenotype only under certain conditions (the restrictive conditions) and expresses the normal phenotype under other conditions (the permissive conditions). One type of conditional mutation is a temperature-sensitive mutation, which expresses the mutant phenotype only at certain temperatures. Strains of E. coli have been isolated that contain temperature-sensitive mutations in the genes encoding different components of the replication machinery. In each of these strains, the protein produced by the mutated gene is nonfunctional under the restrictive conditions. These strains are grown under permissive conditions and then abruptly switched to the restrictive condition. After one round of replication under the restrictive condition, the DNA from each strain is isolated and analyzed. What characteristics would you expect to see in the DNA isolated from each strain with a temperature-sensitive mutation in its gene that encodes the following?a. DNA ligase
b. DNA polymerase I
c. DNA polymerase III
d. Primase
e. Initiator protein
Answer:
a) DNA ligase
Due to temperature sensitivity DNA ligase action is impaired due to presence of multiple nicks but the DNA replication will proceed
b) Encoding polymerase I
Due to temperature sensitivity mutation occurs causing non-corrected strands to be obtained but DNA replication will continue
c) Encoding polymerase III
Replication is stooped here because of the importance of the enzyme in the synthesis of new strand
d) Primase
The enzyme will induce primers in forward and lagging strands

4.Translate the following RNA sequence into a protein chain.
AUGGUUACCAGUCGCUUAUAA
Answer:
1. A codon is a triplet of nucleotides that codes for an amino acid. This amino acid is transported by the tRNA which possesses a complementary anticodon and it gets added to the nascent protein.
2. Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid.
3. the onset of protein production is signaled by the AUG codon which encodes methionine. the stop to the synthesis is given instead by the stop codons (UAA, UAG, UGA)

A) All the progeny may be tall.
B) All the progeny may be short.
C) Some of their offspring may be short.
D) Some of their offspring may be short.
NOTE: EXPLANATION IS REQUIRED.
Answer:
The gene for having a tall stature is a recessive trait. So the man can have only as genotype "aa". The short woman can have instead as genotype either Aa or AA. in the first case, we have both tall and short children while in the second case only short children.
So the answer is A) All the progeny may be tall.

Explanation:
after decomposition in the carbon cycle, put the following steps in order.
- photosynthesis
- fossil fuels or volcanic eruption
- respiration
The correct answer is after decomposition in the carbon cycle, it is first fossil fuels or vulcanic eruption, respiration, and photosynthesis.
Explanation
The carbon cycle is the way that carbon circulates through the atmosphere, oceans, and the Earth's surface and interior through chemical, physical, geological, and biological processes. This cycle is very important because carbon is present in all elements of the Earth. Decomposition is the stage in which organisms (plants and animals) break down and are absorbed by the soil. After millions of years, the carbon contained in these organic wastes becomes the mineral coal that is exploited in mines and extracted for use as fossil fuels, another part of this compound mixes with the processes of the lithosphere and is expelled. in volcanic eruptions. Also, once absorbed by the soil, it feeds the plants that serve as food for different animals that use it for one of their basic processes such as respiration. Once in the atmosphere, the plants absorb carbon again to make their photosynthesis. Therefore, the correct order of the steps of the carbon cycle is Fossil fuels, respiration, photosynthesis.
