Answer:
Heamoglobin is the structure present in red blood cells which is involved in carrying of oxygen from the blood to all parts of the body.
Explanation:
Tertiary Structure : A molecule of heamoglobin consists of four groups of heme and a group of globulin.A molecule of heamoglobin contains four iron atoms to which oxygen molecules get attached. As there are four iron atoms in a molecule of heamoglobin so a single heamoglobin molecule can carry four oxygen atoms.
Quaternary structure: Multi sub unit globular proteins combine to make the Quaternary structure of heamoglobin. Alpha helices are made by the amino acids present in heamoglobin. Non helical segments, short in length, connect the alpha helices. The helical segments are stabilized by hydrogen bonds which results in folding of the polypeptide into the specific Quaternary shape.
Function:
1.The basic function of heamoglobin is that it transfers oxygen from the lungs to different parts of the body.
2. CO2 ions and hydrogen ions are also transported by the heamoglobin.

Answer:
0.91
Explanation:
According to Hard-Weinberg equilibrium, allele frequency in a population remains constant in absence of an evolutionary force. Hardy-Weinberg equilibrium equation for two alleles is as follows:
p + q = 1
where,
p = frequency of dominant allele
q = frequency of recessive allele
Here,
q = 0.09
So, p = 1-q
= 1 - 0.09
= 0.91
Hence, frequency of dominant allele = 0.91
It is important for gametes to be haploid because when the sperm cell fuses with the egg the new cell will have 46 chromosomes. Hope this helps :)
Resident Also called normal or indigenous biota
First, the existence of an indigenous—or residential—microbiota is ancient. Such microbes are found in all animals which can be at the least as complicated as annelids (earthworms); this gives proof for the co-evolution of animals and micro organism for more than 800 million years (Schramm et al, 2003; Savage, 1977).
The indigenous microflora stimulates the host immune system to respond extra speedy to pathogen challenge and, through bacterial antagonism, inhibits colonization of the GI tract with the aid of overt exogenous pathogens.
