A drought killed all the plants in an agricultural farmland. Gradually, due to wind and some birds from nearby areas, new plants

OverLord2011 [107]

Use process of elimination. From what you gave me to read, you can cross off competition. A drought killed the plants and not competition to live. Go down the list of words and look up the definition. Look at nudation and ecesis later because they are different words that may or may not be challenging to understand. You know what reaction and migration is without looking it up. Once you cross off all words answers that don't match up, ask yourself, which remaining answer goes? Nudation is basically new plants that have successfully started growing after a huge environmental change. Ecesis is sort of similar however, the establishment in a new habitat or environment is not from a big change. Therefore, nudation is the correct answer.

In humans, the allele for dimples (D) is dominant to the allele for no dimples (d). At another gene locus, the allele for broad

Inga [223]

Answer:

Explanation:

As given, Allele for dimples(D) is dominant over alleles for no dimples (d), so D is dominant over d.

Allele for broad eyebrows (B) is dominant over allele for slender eyebrows (b), so B is dominant over b.

A man heterozygous for both traits ( DdBb) marries a women who has no dimple and heterozygous fro eyebrow (ddBb)

So cross is = DdBb × ddBb

1). Genotype of the man is DdBb.

2). Genotype of the woman is ddBb.

3). Genotype of the gametes produced by the man are DB, Db, dB and db.

4). Genotype of the gametes produced by the woman are dB and db.

5). Probability that their first child will have dimples 50% or 1/2

6). Probability that there first child will have both dimples as well as slender eyebrows 1/8

Is a cells main function is to produce proteins to be excreted, such as on the pancreas, which organelles would you expect to be

nevsk [136]

Protein synthesis occurs in the cytoplasm, specifically in the ribosomes. Proteins that are meant to be excreted, such as in the pancreas, are produced in the rough endoplasmic reticulum which is a membrane studded with ribosomes. In organs that primarily function to produce and secrete proteins, there will be a larger rough endoplasmic reticulum with more ribosomes.
