Answer:
Felsic, intermediate, mafic, and ultramafic.
Explanation:
If we classify igneous rocks according to their silica composition the ones that have more than 65% of silica in their composition are called felsic; following the felsic rocks we have the intermediate rocks, these have between 55% and 65% of silica in their composition; the rocks that have between 55% and 45% of silica are called mafic and last but not least, we have the ultramafic ones that have less than 45% of silica in them.
If we think about their density, we know that when there is more silica the rock is less dense, so the classification from decreasing to increasing density is Felsic, intermediate, mafic, and ultramafic.
Photos means light
tropos means turning
phototropism means turning towards the light
answer is A
(gravotropizom is like gravity, if you hold that kind of plant sideways, it will try to turn sidewyas, dunno thigmatropism, helio tropizom is turning toward the sun (but ther are other light sources other than sun))
Answer:
secretion
Explanation:
Epithelial cells are juxtaposed, polyhedral cells with much cytoplasm, developed cytoskeleton and polarity. They are juxtaposed due to the presence of cell junctions and little extracellular matrix. The abundance of cytoplasm in this type of cell is related to the intense biochemical activity. These cells perform various metabolic processes such as synthesis and secretion.
For this reason, we can state that many types of epithelial cells perform the function of secretion.
The question is; would a drug that binds irreversibly to these receptors be an effective contraceptive in mammals?, the answer is;Yes; because if the receptors are blocked the sperms will not be able to penetrate the zonal pellucida of the egg. Contraceptives prevents pregnancy by interfering with the normal process of ovulation, fertilization, and implantation.
I think it’s cause brain damage. Let me know!
