The sex cells are called Gametes! Its on Google!
Answer:
B. The mutation results in a new, dominant allele
C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.
D. The mutation occurs in a codon and alters the function of the final protein
Explanation:
All the above things will change the <u>ultimate expression</u> or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.
Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.
This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.
Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.
Answer:
Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.
Explanation
Cells encounter osmosis due to their semi-permeable membranes. Water can flow past cell membranes. A given cell placed into distilled water will have some water flow into it, causing it to burst. A given cell placed in a very concentrated water will have some water flow out of it, causing it to shrivel. A given cell placed in a solution with the same concentration of minerals as the cell will have an equilibrium of water flowing in and out. This is the case of IV (Intravenous therapy) when we want to deliver substances into a human blood. We want to make sure the liquid delivered is as concentrated as the blood to avoid cell shriveling or bursting.
This picture above sums up the 3 cases cells could face in a solution.
Good luck!
Answer:
Pedagogy, andragogy, and gerogogy are three different ori- entations to learning in childhood, young and middle adulthood, and older adulthood, respec- tively.

Zone 3 is a tropical zone, while zones 2 and 4 are temperate.
Since Zone 3 is around the equator and between the two tropics, it is a tropical zone.
Zone 2 and 4 are temperate since they are farther away from the equator, but not too close to the North and South poles.
