Answer: A)They generate electricity by contact

Explanation: triboelectricity can be simply defined as a phenomenon where static electricity is produced when two different materials are vigorously and continuously rubbed or come in contact with each other. This vigorous and continous contact allow electrons to jump from one material (atom) to another there by creating static electricity.

This characteristics is evident when an individual walks across a carpet while wearing a wool socks, as the wool and the carpet vigorously and continuously rub against one another, electrons are transfered from the carpet to the socks which spread all over the surface of the body. (The body becomes negativity charged while the carpet becomes positively charged) This is why the individual will feel a shock sensation when he or she goes on to touch the door knob due to the static electricity generated.

Explain why advanced age has an effect on a woman’s eggs, but not necessarily a man’s sperm.
atroni [7]

Answer:

Due to reduced rate of egg production and several disorders caused by hormonal imbalances

Explanation:

Women lose their fertility at the age of 45 while men are able to produce sperm throughout their life. The reasons however for this are not very clear but it has been found that the rate of production of egg decreases with the advancement of age of females. Also the quality of egg degrades thereby reducing the likelihood of an egg being genetically normal. A woman along with faces several disorders due to the hormonal imbalances and one of these disorders is PCOS, ovarian insufficiency etc., which lead to distorted pattern of menstrual cycle.

3. Large molecules and wastes move<br> through the membrane through
madreJ [45]

Answer: Large molecules and wastes move through the membrane through forms of active transport- endocytosis and exocytosis.

Explanation:

Molecules are moved across the cell membrane via different mechanisms like diffusion, facilitated diffusion and passive transport; however, some very large molecules require specialized types of active transport to cross over- these are endocytosis and exocytosis.

During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of <em>invagination;</em> piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle. Different methods of endocytosis such as <em>phagocytosis, pinocytosis </em>and receptor-mediated <em>endocytosis</em>, take in cells,  water and targeted substances respectively.

Like endocytosis, the particles (signal proteins, neurotransmitters and waste material) are surrounded by a phospholipid membrane. However, in exocytosis, this membrane is formed in the cytoplasm, and merges with the plasma membrane’s interior in a process <em>opposite to </em>endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.

Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to
maw [93]

The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.

<h3><u>Explanation</u>:</h3>

Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.

This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.
