Answer: C. Gravel
Gravel has the highest permeability.
I'll answer what i can
Answer:
Its recommended because it can help fight the flu if you get it
It affects the immune system by training it to target the flu, and gain resistance to it
The best time is during cold, due to the fact that cold helps the virus (heat kills some viruses)
depending on the person depends on whether its effective or not.
<h2><u>Recommended for taking it, i do not know. Sorry for the missing answer.</u></h2>
Its important for the CDC to update it every year because the flu isn't always the same, and can adapt to the shot to where it has no effect.
Answer:
a) The genes present on separate chromosomes exhibit indepedent assortment.
b) The genotype of tall and purple flower parent= TTPp
The genotype of short and purple flower parent: ttPp
Explanation:
a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.
b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.
The genotype of tall and purple flower parent= TTPp
The genotype of short and purple flower parent: ttPp
Answer:
Functions of phosphorus in the body,
i) Formation of bones and teeth. It's a component necessary for forming strong bones and teeth in the body.
ii) It's important in helping to make protein in the body for growth. Since many proteins in the body are phosphorylated for regulating their functions.
iii) Activation of enzymes. This done through phosphorylation.
iv) Gene transcription. It provides structural importance to the gene and protein binding is by the presence of phosphorus.
Deficiency of phosphorus in the body;
i) Weak and fragile bones.
ii) Bone pain.
iii) Fragile teeth.
iv) Stiff joints.
