Answer: a). AA
Explanation: Every trait is controlled by at least a pair of gene. Genes have different forms known as alleles. Alleles can be dominant or recessive. A dominant allele expresses itself in the presence of a recessive allele and masks the effect of a recessive allele. A recessive allele cannot express itself in the presence of a dominant allele and it's effect is masked by a dominant allele. Dominant alleles are usually written in upper cases such as A, T, while recessive alleles are usually written in lower cases such as a, t. The two alleles that determines a trait is called a genotype. A genotype can be homozygous if the two alleles are identical such as in AA or aa
and can be heterozygous if the two alleles are not identical such as in Aa, Tt.
They are called Eukaryotic cells or Eukaryotes
Answer:
Reduced reabsorption of salts and nutrients from the proximal tubule.
Explanation:
The proximal convoluted tubules are the site for reabsorption of the largest amount of solute and water from the filtered fluid. It reabsorbs 65% of water, electrolytes such as Na+ and K+, almost 100% of the filtered glucose and amino acids and other electrolytes such as Ca2+, Mg2+, etc.
The simple cuboidal epithelial cells of the proximal convoluted tubule have a prominent brush border of microvilli on their apical surface. These microvilli serve to increase the surface area for reabsorption and secretion. Destruction of these microvilli would reduce the reabsorption of the above-mentioned salts and nutrients from proximal convoluted tubules.
Without seeing the image ...I can suggest C as bacteria and archae are the most similar besides all other options ! am I right !!!
Answer:
About four or five days after fertilization, a group of cells forms a ball-like
structure. What is the name of this structure?
After fertilization, a zygote is formed afterwards which carries the genetic materials passed across from both parents
Explanation:
