what is embryogenesis???
Answers
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.

Answer: X
Explanation:
Because we see 2 X's in the karyotype, that means that this person can only give an X to their son, who is XY.
Males have XY chromosomes however females have XX chromosomes
Since a female does not have any Y chromosomes she wouldn’t be able to provide the child with a Y chromosome
If she had a son then she would’ve provided him with an X chromosome and the father would have provided the son with a Y chromosome because a male needs X and Y both

after decomposition in the carbon cycle, put the following steps in order.
- photosynthesis
- fossil fuels or volcanic eruption
- respiration
Answers
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.

Answers
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.

4.Translate the following RNA sequence into a protein chain.
AUGGUUACCAGUCGCUUAUAA
Answers
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)
4. Met-Val-Thr-Ser-Arg-Leu-Stop
1. Which of the following may not likely be possible when a tall man marries a short woman ?
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.
Answers
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.
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
Answers
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.

In eukaryotes transcription takes place in the _________. translation takes place in the ________.
1. cytoplasm/cytoplasm
2. nucleus/cytoplasm
3. nucleus/ribosomes
4. ribosomes/nucleus
Answers
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.

Duchenne Muscular Dystrophy (DMD) is a sex-linked trait that causes muscular weakness that gets worse as a person ages. Which is most likely true of Duchenne Muscular Dystrophy? A. DMD can only be inherited by females. B. Females with DMD always have a mother with DMD. C. The gene for DMD is located on the X or Y chromosome. D. The gene for DMD is most active in the cells of the reproductive organs.
Answers
Answer: C
Explanation:
DMD is s*x linked trait. This means that we have to consider the chromosomes XX and XY. For a male to have DMD, this means the mom must must pass down the allele for DMD. The mom can either be a carrier OR she has to have DMD and the dad can only pass down the Y chromosome. For a daughter to get DMD, this means the dad has to have the allele for DMD and so does the mom. That means that the dad has DMD and the mom can either have DMD or be a carrier. Based off of this logic, we know that the answer isn't B. Because they tell us DMD is s*x-linked trait, it means that the gene for DMD is on the x or y chromosome.
