Answer: Enables the spermatozoa to penetrate the ova

Explanation: It contains certain digestive enzymes (hydrolytic enzymes) that helps the sperm to tunnel through the zona pellucida of the ova. It mediates the union and binding of the membrane with the egg.

Answer:

Sexual reproduction requires two parents. Each parent contributes a gamete - a sex cell that has half of the normal DNA of a regular body cell. In males, the gametes are sperm and in females, the gametes are eggs.

When these two gamete combine during fertilization, the result is a zygote, which then continues to develop into an embryo.

The number of cells of Staphylococcus aureus present into the open wound, which divides by binary fission once every 30 minutes, after 30 minutes, one hour and 12 hours will be 2, 4 and 1.7 × 10⁷ cells respectively.

Binary fission is the method of asexual reproduction. It is the process by which a cell divides to form two daughter cells.

According to the question, the cell divides into 2 once after every 30 minutes.

The number of cells can be calculated by the formula: 2ⁿ

(where n = number of times the cell will divide in the given time period)

Therefore after 30 minutes, number of cells = 2¹ = 2.

Similarly, after 60 minutes, number of cells = 2² = 4.

In 12 hours, the cell will divide 24 times,

Hence the number of cells will be = 2²⁴ = 1.7 × 10⁷ cells respectively.

If replication had to be accomplished in an 8-hour s phase and replication forks moved at 50 nucleotides/second, The minimum number of 46 origins required to replicate the human genome.

A double-stranded DNA molecule is copied during replication to create two identical DNA molecules. One of the most fundamental processes that take place within a cell is DNA replication. Between the G1 phase and the G2 phase, the cell cycle's S phase (also known as the "synthesis phase") is when DNA replication occurs. Since precise genome duplication is essential for effective cell division, the S-phase mechanisms are strictly regulated and highly conserved.

Before the interphase, in the S phase of the cell cycle, DNA synthesis or replication takes place. By doing this, the cell's genetic material is copied before mitosis or meiosis, leaving enough DNA for cell division.

Answer:

The sun's heat causes differential heating of the earth's surface and water bodies causing changing wind patterns.

Explanation:

The amount of sunlight received varies on various factors like

1. Insolation

2. Latitude

3. Altitude

Maximum sunlight is received at the equator while minimum sunlight is received at the poles.

Because of varying amounts of sunlight received, the surface and water bodies heat differently. This causes the wind over the surface to warm and cool differently.

The warm air being lighter in weight rises and is replaced by the heavier colder air. This leads to the formation of wind patterns.

The global winds are called trade winds.

An attribute of COVID-19 is excessive inflammation, which is controlled by regulatory T cells (Tregs). In addition to an intriguing role for interleukin (IL)-6 and IL-18, we discovered a noteworthy profile in Tregs from patients with advanced disease. Severe patients were distinguished from healthy people by the production of proinflammatory mediators and an improved suppressive profile that comprised increased Treg proportions. This suggests that these cells had a negative impact on COVID-19 and that there might be a cause for some of the recovery-related issues that are still mostly unexplored. The prognosis of tumor-infiltrating Tregs, which frequently exhibit this tendency, is generally poor.

Capillary action cohesion, Amazing water adhesion, bubbling beakers specific heat capacity, Magic pepper polarity , and pouring water  demo capillary action.

Like molecules (of the same substance) have the ability to adhere to one another due to attraction to one another, which is known as cohesion. Adhesion is the ability of certain molecules or surfaces to stick to one another. Solids, for instance, have high cohesive qualities, which prevent them from adhering to surfaces with which they come into touch. Gases, however, have a poor cohesiveness. Water is cohesive and sticky in nature. A sphere is created when water molecules adhere to one another. Cohesive forces have produced this. Water molecules reaching the container's surface are at a greater level when enclosed in a tube (see Meniscus). This is a result of the adhesive force between the molecules of water and those of the container.

Magic pepper is an experiment in which pepper polarizes easily , the electrons move to one end of the pepper gain and protons move to the other end . Capillary action is the movement of water within the spaces of a porous material due to the forces of adhesion , cohesion and surface tension.

The difference between the  age structure graphs of non growing, slowly growing and rapidly growing countries is the birth rate and death rate of countries in each class.

There are so many countries in the world and each of the countries that we have in the world is unique in terms of the demography of the country. The demography has to do with the distribution of the people in a place according to age, sex and geographical location.

For the rapidly growing countries, we would notice that the age structure lies mostly towards the elderly. This implies that the birth rate and the death rate of the population ha achieved a sort of equilibrium.

For the slowing growing countries, the birth rate remains high but not so much as high as the non growing countries. This implies that the population of the countries are also within a manageable limit.

For the nongrowing countries, the birth rate is very much higher than the death rate thus there is a population explosion which puts pressure on the economy.
