Answer:
distal convoluted tubule
Explanation:
This is the region of the nephron downstream the macula densa ,which extends the to convulence of the collecting duct.Due to response to mineralocoticoid aldosterone they can be categorised as Distal Convoluted 1 and Distal convoluted 2. This steroid hormones is responsible for homeostatic control of hyperkalemia.
The DCT cells are simple cuboidal epithelium.The stained or pointed part of the image represented this possess this shape,they are therefore portion of DCT. Besides the stained cells are located above the glomerulus ()in the cortex as indicated,therefore they can not be the proximal which must be below the glomerulus, based on the shape ascending and descending loop of Henle (despite located in the cortex too).
The functions of the DCT is in the absorption and secretions of ions(majorly ca+,Na+ and chloride ions.By secreting hydrogen and reabsorbing HC03 ions ,the pH of the urine is maintained.
Answer:
The parents are of genotype heterozygous dominant and homozygous recessive. Supposing the dominant allele is N and the recessive allele is n, one of the parents will be Nn while the other nn. The phenotypic (based on visible characteristics) ratio will be 1:1 for dom/rec and rec/rec

Answer:
Each daughter cell will have 8 chromosomes. That is correct. By the end of mitosis, there are two daughter cells. Each daughter cell will have the same amount of genetic material as the parent 8 chromosomes.

Answer:
Cell Z has the greatest solute concentration
Explanation:
- The water moves from higher potential to lower potential.
- More the solute concentration in solution the lower will be water potential.
- External mechanical pressure increases the water potential.
Cell Z has more solute concentration, So it require more external pressure to equalize its internal water potential with external water potential for stopping the movement of water from high potential to lower potential.
<em>Remember the maximum potential of water is zero at standard temperature and pressure.</em>
