The mesoderm is one of the germ layers present in an embryo and it develops primarily into muscles and organs. The radioactive marker would therefore be visible in the adult organism's cardiac muscle cells, smooth muscle cells, skeletal muscle cells, red blood cells and many other such specialized cells.
Answer:
Both are type of natural selection and ultimately lead to selection of a set of phenotype over the entire available genotype spectrum.
Explanation:
Both the stabilizing selection and directional selection are two forms of natural selection
Also in both the selection process, a new population with a better fitment to the prevailing environmental and physical conditions evolves.
In stabilizing selection, an average phenotype is selected over extreme variation. However, by this process of selection the genetic variance of the population will decrease.
However in directional selection, phenotypes at one end of the existing variation are selected over the entire spectrum
The best answer is organisms...
Cells only grow to replace other cells that die off and allow for the continued existence of the organism.
Please correct me if I'm wrong... :)
Answer:
Frequency of recessive allele 
Explanation:
Given -
Total Population size = 919
Number of individual with recessive genotype = 341
Frequency of recessive genotype
Frequency of recessive allele 
Hence, option C is correct
