The connective tissue layer surrounding bone is called the periosteum. It has an outer fibrous layer and an inner osteogenesic layer.
Answer:
Deleterious alleles appear sporadically in a population
Explanation:
A population with a deleterious allele will have no or few individuals that have the ability to pass along these traits. These alleles appear less in a population because of selective pressure but they are not always absent. The alleles appear less often but are are not always passed on and the others that are genetically fit are able to pass along their genes. The reason the population equilibrium is not zero is because these alleles do appear but they are not necessarily passed along. These individuals may not be able to reproduce or reach the age of reproduction.
Deleterious alleles appear more often, making individuals less fit genetically, i.e. they pass fewer copies of their genes to future generations. Put another way, natural selection purges the deleterious alleles.
There is a 50% probability that the flowers of a plant with pink flowers parents will have pink flowers due to incomplete dominance.
The genotypes and phenotypes that we will employ to address this issue are as follows:
RR - Red
RW - Pink
WW - White
They would have the RW genotype as the first parent plant is pink. They would have the WW genotype because the other parent is white. When the Pink flower parents are crossed, the children that might be expected from this cross
RW x RW
The progeny will be : 1 RR (Red), 2 RW (Pink) and 1 WW (White)
This shows that there is a 50% probability that the progeny will have the RW genotype and thus the pink phenotype. Additionally, we can observe that there is a 25% likelihood that the progeny will have the WW and RR genotype and the white and Red phenotype.

Answer: Sea stars move using a water vascular system. Water comes into the system via the madreporite. It is then circulated from the stone canal to the ring canal and into the radial canals.
Explanation: The radial canals carry water to the ampullae and provide suction to the tube feet.
If producers were removed from an ecosystem, it would fall apart. Producers are the organisms at the bottom of the food chain, which produce glucose and nutrients for consumers. If producers were removed from an ecosystem, the consumers would have no nutrients and die, causing their predators to die, and so on.
