Only a fraction of the genes in a cell are expressed at any one time. The variety of gene expression profiles characteristic of different cell types arise because these cells have distinct sets of transcription regulators

Answer:The intensity of sunlight decreases rapidly with depth. The depth of the water not only affects the colors of light that are noticeable underwater, it also affects the intensity, or amount of light. Within the first 10 m, water absorbs more than 50 percent of the visible light energy
Answer:
The correct order is - 3. ribosomes 5. the endoplasmic reticulum 1. the Golgi apparatus. 4. transport vesicles. 2. the plasma membrane.
Explanation:
The protein needs to be transported from the cytoplasm to out of the cells for their target site, for example, insulin and enzymes. The protein synthesizes at the ribosome by the process of translation. It transported to the endoplasmic reticulum and move to the Golgi apparatus where it packaged and modified in the transport vesicles so it can move to, and pass through the plasma membrane.
Thus, the correct order is - 3. ribosomes 5. the endoplasmic reticulum 1. the Golgi apparatus. 4. transport vesicles. 2. the plasma membrane.
Because that's when they are safest from their predators. The predators are still hiding and waiting out the rain.
50% or 0.5 is the probability that the offspring will have a cleft chin.
Explanation:
Data given:
Cleft chin = dominant, genotype CC
one parent, heterozygous so genotype, Cc
other parent = no cleft chin, genotype is cc (recessive)
probability of child with cleft chin =?
The cross between the given genotype will be shown in punnet square:
C c
c Cc cc
c Cc cc
The results obtained from the cross shows that 50% chances of the progeny having cleft chin.
The phenotype ratio: cleft chin: no cleft chin
1:1
the genotype ratio of the progeny
heterozygous dominant : recessive homozygous
1:1
