Answer:
d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.
Explanation:
Estrogens are small lipophilic molecules synthesized from cholesterol. This steroid hormone (estrogen) is able to directly enter into the cell nucleus to bind with their corresponding receptors. Subsequently, estrogen-receptor binding stimulates these receptors to form dimeric structures that bind to DNA and thus activate gene expression. Estrogen receptors interact with DNA and activate gene expression through zinc finger domains composed of four (4) cysteine residues surrounding a zinc atom.
Answer: Higher.
Explanation:
It the ozone layer disappeared, life on the earth would be exposed to higher concentration of ultraviolet rays.
These rays are very harmful for the organism present on the earth. Exposure to the higher concentration of ultraviolet rays increases the chances of cancer in the organism.
