Answer:

Cells provide six main functions. They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.

A cell is the structural and functional unit of life. Each cell contains smaller organelles that perform various functions such as metabolism, transportation and secretion of substances. Because some cells perform specific functions, they have special modified structures. For example, red blood cells are the oxygen carriers in the body. They lack a nucleus to make more space for the oxygen-carrying pigment, hemoglobin. The various structures and organelles in a cell float in a liquid called the cytoplasm.

gayaneshka [121]

Answer:

The intercalated cells in the distal convoluted tubule of a nephron can cause and increase or decrease in body pH.

Explanation:

The renal collecting duct is the nephron segment where the final urine content of acid equivalents and inorganic ions are determined.

Two types of cells regulate the acid-base and volume homeostasis.

Intercalated cells, which express acid-base transporters and vacuolar H+-ATPase, maintain an apropriate acid-base balance and principal cells that express the epithelial sodium channel ENaC and aquaporin 2, regulate electrolyte reabsorption.

Filtered bicarbonate is predominantly reabsorbed from the proximal convoluted tubule about 80% and the remaining bicarbonate is reabsorbed from the thick ascending limb of the loop of Henle, the distal nephron, specifically the distal convoluted tubule & the connecting tubule, and finally the cortical and both the outer and inner medullary collecting duct.

Intercalated cells are enriched in mitochondria, and express proteins involved in transport of proton equivalents such as vacuolar H+-ATPase, carbonic anhydrase II and bicarbonate transporters. There are two types of intercalated cells Type-A and Type-B.

Black coat color in horses is conferred by the presence of a dominant B allele. Chestnut horses are genotype bb. A population of
AysviL [449]

Answer:

Frequency of B allele is 0.6681

Explanation:

If p represents the frequency of dominant allele and q represents the frequency of  recessive allele, according to Hardy-Weinberg equilibrium:

p + q = 1

p² + 2pq + q² = 1

where p² = frequency of homozygous dominant genotype

q² = frequency of homozygous recessive genotype

2pq = frequency of heterozygous genotype

Given that number of recessive chestnut horse = 28

Total horses = 226 + 28 = 254

frequency of b² genotype = 28/254 = 0.1102

frequency of recessive b allele = √0.1102 = 0.3319

So, frequency of B allele =

1 - 0.3319 = 0.6681

Hence frequency of B allele is 0.6681
