Answer:

Eukaryotes:

-Organisms with a well defined nucleus are known as eukaryotes. such cells are called as eukaryotic cells.

- Their nucleus is enclosed within the nuclear membrane.

- They do not posses a mitochondria.

- The cell wall is the outer most layer of a eukaryotic cell (only plant cells have a cell wall)

- The cells are divided by a process called mitosis.

Eg: Plants, Animals.

Prokaryotes:

- Organisms without a well defined nucleus are known as prokaryotes. Such cells are called as Prokaryotic cells.

- They lack nuclear membrane.

- Mitochondria, Golgi bodies, chloroplast and lysosomes are absent.

- The genetic material (DNA) is present on the chromosome.

Eg: Every organism coming under the kingdom monera.

If the diameter of the afferent arterioles leading to the glomerulus increases (vasodilation) net filtration pressure will incre
Vinvika [58]

True. If the diameter of the afferent arterioles leading to the glomerulus increases due to vasodilation, which ultimately increases the net filtration pressure.

The filtration of blood occurs in the kidney, an excretory organ. The kidney is composed of numerous small units called nephrons, which is responsible for the blood filtration.

Glomerulus is part of nephron and the glomerular filtration occurs in the renal corpuscle of the kidney. This process is driven by hydrostatic and colloid osmotic pressure.

These pressures are collectively called net filtration pressure, which is influenced by the diameter of afferent arterioles.

If the arterioles constricts, net filtration pressure will decrease and if arterioles dilates, net filtration pressure will increase. This mechanism is regulated by neural, renal and hormonal regulation.
