Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes. This picture of the human chromosomes lined up in pairs is called a karyotype.
Of the 23 pairs of chromosomes, the first 22 pairs are called "autosomes." The final pair is called the "sex chromosomes." Sex chromosomes determine an individual's sex: females have two X chromosomes (XX), and males have an X and a Y chromosome (XY).
The answer to the first one is Pleiotropy (when one gene affects many traits) and the second one is a sex influenced trait
Answer:
They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA). This mRNA travels to the ribosomes, which translate the code provided by the sequence of the nitrogenous bases in the mRNA into a specific order of amino acids in a protein.

Answer:
B. food production
Explanation:
In the example above described, salinity conditions (3%) completely prevented radicle development (0 mm). Salinity conditions may alter plant development by inhibiting the uptake of nitrogen, and by limiting water intake. Moreover, it has been shown that the excessive accumulation of chloride ions in plant cells may have toxic effects on plant growth, causing ionic stress and thus leading to nutrient deficiency.
I think the answer is A or C but I'm leaning more towards C. If there is no birds to eat the insects, the insect population would grow more and they would eat more of the leaves.
