The correct answer is an apocrine gland.
The apocrine gland is a type of exocrine glands with a specific kind of secretion by membrane budding. The apical portion of the secretory cell of the apocrine gland pinches off, enters the lumen and loses part of its cytoplasm. The example of the apocrine gland is the sweat gland.
I now chlorophyll is the main compound (or one of them) and I'm pretty sure chlorophyll is a protein so I'd pick "D".
Answer:Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment
Explanation:
Radioactive dating can determine the age of minerals and fossils in each layer of rock.
Explanation:
Radioactive dating is the most commonly used geological method to determine the age of rocks and fossils layered in the layers of rock on the basis of their natural radioactive decaying.
With the help of the known rate of radioactive decay of isotopes, different types of radiometric dating are done depending upon the material found in the rock layers, like uranium-lead dating or potassium-argon dating.
Radiocarbon dating helps to record organic content in rocks like bones, shells, etc. Age of fossils sediment over sedimentary rocks is determined by combining with the bracketing method.
