Answer:

the seeds of plants contain angiosperm (flowering plants) seeds consist of three genetically distinct constituents: (1) the embryo formed from the zygote, (2) the endosperm, which is normally triploid, (3) the seed coat tissue derived from the maternal tissue of the ovule.

Mitosis can occur in both haploid and diploid cells, but meiosis cannot occur in haploid cells. Why not?.
allochka39001 [22]

Mitosis can occur in both haploid and diploid cells because it is equational division where the number of chromosomes remain the same after division. But meiosis cannot happen in haploid cells because it is reductional division and haploid cells do not have any extra copy of chromosomes to be halved.

Mitosis is the cell division where the number of chromosomes do not change after cell division. It usually happens in the somatic cells of the body. Cancer cells also undergo mitosis

Meiosis is the cell division where the number of chromosomes are halved after cell division. The process of meiosis occurs in two phases: meiosis I and meiosis II. The germ cells of the body undergo meiosis.

If one compares the base sequences of related genes from different species, one is likely to find that corresponding ________ ar
just olya [345]

Answer:

B. introns; exons

Explanation:

Related genes from different organism usually translate to proteins of indispensable functions. This means that the proteins must be similar in terms of amino acids produced. Therefore the coding region must be highly conserved. These can be found in the introns. Conversely, exons are not a part of the coding sequence and therefore not required for translation. These sequences may be less conserved.

If a bacteria cannot ferment glucose, why not test its ability to ferment other carbohydrates?
nalin [4]

If a bacteria cannot ferment glucose, then we do not test its ability to ferment other carbohydrates because the glucose is monosaccharides, the bacteria required enzymes that used to ferment glucose.

Bacteria cannot ferment carbohydrates because carbohydrates may include non-reducing sugar like sucrose and lactose, which is disaccharide, that must be cleaved into monosaccharides. Not all, bacteria can do this to may or may not ferment sucrose.

Many microorganism can grow in the base broth without the carbohydrates, but if they can ferment a sugar that is available. It is possible that one bacteria metabolize some sugar but can't work on other.
