Answer:
B ) Valves
Explanation:
Valves allow blood to flow only in one direction and prevent the backflow.
Nonpolar and small polar molecules<span> can pass </span>through the cell membrane<span>, so they diffuse </span>across<span> it in response to concentration gradients. Carbon dioxide and oxygen are two </span>molecules<span> that undergo this simple diffusion </span>through<span> the </span>membrane<span>. The simple diffusion of water is known as osmosis.</span>
Answer:
Mutation.
Explanation:
Mutation may be defined as the sudden heritable change in the DNA sequence of the organisms. Mutation can results in the change in the genotype and phenotype of the organisms.
Two main types of mutation are spontaneous mutation and induced mutation. Induced mutation occurs intentionally with the help of the mutagens. Spontaneous mutation is the natural mutation that occurs for the no known reason.
Thus, the answer is spontaneous mutation.
Hardy-Weinberg Principle
Genotype frequency equation
Where p² is the freq of homo dominant genotype, 2pq is the freq of heterozygous genotype and q² is the freq of homo recessive genotype.
Allele frequency equation
p + q = 1
Where p is the frequency of dominant alleles and q is the frequency of recessive alleles.
Yellow eyes in the frog offspring is a phenotype (physical trait) that would be a expressed by a geneotype (YY or Yy). This frequency, 0.85 includes: p² + 2pq
0.85 + q² = 1
q² = 0.15
p = 
Then p + 
= 1
1 - = p
p = 0.613
61%
Answer:
Explanation:
Cerebral Palsy is a brain injury it occurs while the brain is developing this could be before, during, or after birth. Mutation which is a sudden heritable change in the genome of an individual can result into cerebral palsy when the child is still developing. Mutation affects the gene changing it from it normal state to an abnormal one some mutation can be beneficial but for palsy it is detrimental one affecting the growth and development of the child.
severe jaundice in the infant could also lead to cerebral palsy in an infant child
This damage affects child’s muscle control, muscle coordination, muscle tone, reflex, posture and balance.
It can also impact a child’s fine motor skills, gross motor skills, and oral motor functioning
