Explanation:
the process which takes place in guard cells but not in other epidermal cells is?
Answer:
guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck
Photosynthesis
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.
Difference in guard and epidermal Cells:Two guard cells form a stoma, controlling the gas exchange of the plant by regulating the size of the stoma whereas epidermal cells provide a protection to the plant from the external environment.
Photosynthesis does not take place in epidermal cell because:The epidermal cells that make up this skin are transparent. As most epidermal cells lack chloroplasts, they can't perform photosynthesis, or the use of sunlight to convert carbon dioxide and water into glucose and oxygen.

Speckled trout and red drum both prey on mullet along the Texas coastline. Dead zones are caused by excessive nutrient pollution, along with other factors that deplete the oxygen from the water. What likely effect would increasing dead zones have on the populations of speckled trout, red drum, and mullet?
a
All three populations would increase.
b
Mullet populations would increase, but trout and drum populations would decrease.
c
Mullet populations would decrease, but trout and drum populations would increase.
d
All three populations would decrease.
Answer:
all three populations would decrease
Explanation:
Most likely effect would increasing dead zones have on the populations of speckled trout, red drum, and mullet, All three populations would decrease. Thus, option "D" is correct.

Lysogenic viruses do not
Answer:
Unlike a lytic virus, a lysogenic virus does not cause the host cell to lyse away. A lysogenic virus can remain inactive for a period of time. In lysogenic infection, viral DNA gets integrated with the host cell's DNA, where it is copied along with the host cell's DNA when the host cell replicates.

Which of the following statements correctly summarizes the steps of protein synthesis? Transcription & Translation
a.) mRNA copies DNA into an amino acid chain in the nucleus. Once out of the nucleus, it folds into a protein by ribosomes.
b.) DNA is transcribed into mRNA in the nucleus. mRNA then leaves where it is read by a ribosome to form an amino acid chain.
c.) DNA is transcribed into amino acids in the nucleus before it leaves into the cytoplasm. In the cytoplasm it binds with mRNA to form amino acids.

A man and a woman have a child together. The mother's blood type is type O and the child's blood type is type A What could the father's genotype be?
Answer:
iAiA or iAi = Type A
Explanation:
Blood group in humans is controlled by a gene with multiple alleles. The alleles iA and iB are co-dominant over one another but dominant over allele i. In the blood type:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, a man and a woman have a child together. The mother's blood type is type O (ii) and the child's blood type is type A (iAi). This means that the father's blood type must be a type A with genotype "iAiA or iAi".

Mrs. Smith has blood type A. Mr. Smith has blood type B. Their first child has blood type AB. Their second child has blood type O. Now is Mr. Smith justified? What are Mr. and Mrs. Smith’s genotypes for these two genes?
the only possibilities for the childrens genotypes are; A and AB, so the fact that the child has a blood type of O isn't possible
The genotypes of Mrs. Smith and Mr. Smith are AO and BO, respectively. Therefore, the blood group of the offspring will be A, B, AB, and O.
What is Genotype?Genotype is the genetic makeup of an organism. Genotype refers to the alleles which are present in an organism.
ABO blood group shows multiple allelism which means it has more than two alleles which are A, B, and O. A and B alleles show co-dominance and O allele is recessive allele.
As per the information, Mrs. Smith has blood type A (genotype of Mrs. Smith could be AA/AO), and Mr. Smith has a blood group B (genotype could be BB/BO).
The blood group of the first child produced is AB. So, the genotype of this child is AB only. And, the blood group of their second child is O which is recessive. So, the genotype of the child will be OO only (homozygous).
Therefore, the genotype of the parents Mrs. Smith and Mr. Smith for their children to have blood group AB and O must be AO and BO only.
