Explanation:
The epidermis of a leaf contains which of the following structures
stroma
vascular bundles
stoma
chloroplasts
Answer:
The correct answer is - stoma.
Explanation:
Stoma or stomate is a tiny pore that is found on the surface or in the epidermis of the leaf of plants. These tiny pores present all over the leaf and help in the exchange of gases.
The guard cells are present around these pores and help in the opening and closing of these pores. The carbon dioxide is take in and oxygen moves out with the help of these structures and they assist in the process of transpiration.
Answer:
Stoma
Explanation:
The epidermis is the outer layer of a leaf that houses the stoma

What purpose does the endosperm serve in the seed?
Answer:
Supporting embryonic growth
Explanation:
The endosperm plays an important role in supporting embryonic growth by supplying nutrients, protecting the embryo, and controlling embryo growth by acting as a mechanical barrier during seed development and germination.
Answer:
Supporting embryonic growth
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.

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.

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".
