Ans. Option (IV).

Mosses can be defined as non-vascular, flowerless plants that are found in shady or damp regions and reproduce via haploid spores. During reproduction in moss, haploid male gametes or spores are released into surrounding environment that fuse with female spores to form zygote that develop into mature sporophyte.

Angiosperms are vascular, flowering plants that reproduce by seeds. During reproduction in angiosperms, haploid male gametes or pollen grains are released into surrounding environment that fuse with female gametes or eggs to form zygote that develop into seed.

Thus, the correct answer is option (IV).

Answer:

This lack of fossil data is expected, because the fossil record is incomplete.

Explanation:

Fossilization is a slow, complex and extremely rare process that depends on several favorable conditions for the conservation of traces or materials left by an organism:

1 - Rapid burial of the material;

2 - Presence of rigid parts that are more resistant to degradation;

3 - The type of sediment should be thin and less prone to erosion.

4 - The environment in which the material is located should be low in oxygen to avoid degradation due to oxidation.

5 - The temperature of the place where the material is buried should preferably be cold because the action of decomposing microorganisms in these environments is much lower.

Therefore, it is very common and expected that the fossil record is incomplete.

Antidiuretic hormone (ADH) is important in maintaining homeostasis in mammals. ADH is released from the hypothalamus in response

ella [17]

Answer:Brainly.com

What is y

Answer.

ADH is released from the hypothalamus in response to high tissue osmolarity. In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries.

Explanation

. This option is the mechanisms of regulation of osmoregulatory balance in urine production by the kidney

ADH responds to high solute potential of the blood(high osmolarity) by stimulating the opening of transmembrane proteins AQUAPORINS in the walls of the distal and collecting tubules

This promotes influx of Solutes from the passing tubules into the peritubular capillaries.Water follows by osmosis(reabsorption),untill the osmolarity of these fluids drops.

As this occurs the hypothalamus stopped the production of ADH, the aquaporins closes up,solute influx into peritubular capillaries stoped and therefore water influx

This is negative feedback Mechanism.it is an example of homeostatic process of maintaining water balance of the body during urine formation .
