Biology

Oliga [24]3 years ago

Answer:

D

Explanation:

The punnett square showing the cross Yyrr x YyRr is attached

The gametes that the Yyrr individual can produce are either Yr or yr. The yyRr individual can produce YR, Yr, yR, or yr. The possible genotypes are shown in the punnett square.

For a pea to be yellow and wrinkled, it would have the genotype YYrr, or Yyrr (as yellow is dominant (Y) and wrinkled is recessive (r)). Therefore, we count the number of those genotypes of the total genotypes we get.

There are 4/8 that are either Yyrr or YYrr, so the answer is d.

Which type of protein binds a ligand on the cell surface or within cells, often initiating a downstream signaling cascade or alt
kkurt [141]

Answer:

The type of protein that binds a ligand on the cell surface or within cells are transmembrane receptors. These proteins have 3 domains: an extracellular part that does the binding, a hydrophobic domain that extends through the membrane, and an intracellular region that transmits the signal. The most common membrane-anchored receptors are: G protein-coupled receptors, receptor tyrosine kinases, and ligand-gated ion channels.

1. Define fitness as it used to describe adaptation
aliya0001 [1]

Answer:

In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.

Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.

For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.
