Answer:
Modified apocrine sweat glands
Explanation:
The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.
As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.
This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest
Answer:
A pollen tube grows from the pollen grain into the ovary
Explanation:
Water is needed for fertilization in several plant groups because the sperm needs to swim to meet the non-motile eggs of the female organs.
<em>However in angiosperms, the pollen germinates and a structure known as pollen tube which contains the male gametophyte (sperm) grows into the ovary where the ovule is located and the male gametophyte is deposited in the ovule to initiate the fertilization process.</em>
<em>Hence, water is really not necessary for fertilization in the angiosperms.</em>
