No, her height is within normal range, and her pituitary gland is working normally.

<h3>Why is the pituitary gland called the master gland?</h3>

The pituitary gland is occasionally called the "master" gland of the endocrine system because it maintains the functions of many of the other endocrine glands.

The pituitary gland is no larger than a pea and is found at the base of the brain.

Thus, her height is within normal range, and her pituitary gland is working normally.

What was a conclusion that Mendel drew from the F2 generation of this cross?
Ber [7]
<h3><u>Answer;</u></h3>

That parental traits that were not observed in the F1 reappeared in the F2.

<h3><u>Explanation</u>;</h3>
  • Mendel accounted for the observation that traits which had disappeared in the F1 generation reappeared in the F2 generation by proposing that traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.
  • <em>I</em><u><em>t was important that Mendel examined not just the F1 generation in his breeding experiments, but the F2 generation as well, because parental traits that were not observed in the F1 reappeared in the F2.</em></u>

What are some advantages and disadvantages of
andrew-mc [135]

Answer:Asexual Reproduction Sexual Reproduction

Advantages Time Efficient; no need to search for mate, requires less energy Variation, Unique., organism is more protected

Disadvantages No variation - if the parent has a genetic disease, offspring does too. Requires two organisms, requires more energy

Explanation:While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction

DNA _____.
Ne4ueva [31]

Answer:

Answer:

The correct answer would be "contains coded information for the creation of proteins".

DNA or deoxyribonucleic acid is a polymer of nucleotides.

It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.

In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.

The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.

It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.
