Answer:
A
Explanation:
Meiosis results in gametes with one half the number of chromosomes of the parent cell.
Answer:
The phenotype ratio of HhGg x HHGg is 9:3:3:1.
Explanation:
The phenotypic ratio is concerned with the relative number of the offspring man manifesting a particular trait or combination of traits. It can be determined by making test cross and then finding the frequency of the traits.
phenotype ratio of HhGg HHGg is a different di-hybrid cross. One 'g' will be combined with the one 'h'. In result the huge will be dominant that of small and green will be dominant to that of blue.
HhGg × HhGg ( huge/green × huge/green)
From the below stated table we can conclude the ratio which is like huge/green =9,
Small/green = 3,
huge/blue=3,
small/blue = 1.
Hence it is proved that the phenotypic ratio will be 9:3:3:1.
Answer:
The bulging eyes of most frogs allow them to see in front, to the sides, and partially behind them. The eyes help push the food down its throat. Eyes positioned atop the head give frogs a field of vision of almost 180 degrees. This peripheral vision helps them spot predators and prey.

Answer:
True
Explanation:
The fluid mosaic model is often used to describe the cell plasma membrane as having proteins randomly scattered across its surface in a mosaic manner and the fluidity allowing for movement of proteins within the phospholipid bilayer.
