Haploid cells join to form an organism that has a complete set of chromosomes describes a process associated with meiosis.
What do you mean by meiosis?Meiosis occurs in the primordial germ cells, which are distinct from the body's normal somatic cells and are designed for sexual reproduction. A germ cell goes through interphase, during which the entire cell, including the genetic material.
In sexually reproducing organisms, meiosis is a unique type of cell division that results in the production of gametes, such as sperm or egg cells. It involves two division rounds that produce four cells with just one copy of each chromosome.
Gametes, or sex cells, are produced during meiosis. Each of the four haploid daughter cells produced during meiosis has half the number of chromosomes as the parent cell.

Explanation:
evaporation is the process of a liquid changing from liquid to gas and can happen in a small and large scale :)
Answer:
The changing of a liquid into vapours or gas is called evaporation. Evaporation is used to obtain a solid substance that has dissolved in water or any other liquid. The dissolved substance is left as a solid residue when all the water has evaporated.

2. Explain the difference between cohesion and adhesion as they apply to water, as well as the results that they produce.
Answer:
Water is drawn to water due of its cohesion.
Water is drawn to other substances due to its adhesion.
Explanation:
Surface tension on water is created by cohesion, which binds hydrogen bonds together. Adhesive forces drive water toward other molecules because water is attracted to them.
Adhesion is what distinguishes a water drop from a droplet. Water has a high degree of cohesion—it has the highest cohesion of all the nonmetallic liquids. While water's cohesive properties cause it to stick together and form drops, chemistry and electricity are also involved at a more detailed level in order for this to be possible.
Cohesion and adhesion are properties of water that involve its molecular interactions. Hydrogen bonding between water molecules causes cohesion, which causes surface tension and vigorous liquid column movement in plants. As opposed to capillary action, which allows water to ascend confined tubes defying gravity, adhesion is the attraction between water molecules and other things.
Cohesion in water arises from the hydrogen bonds formed between its molecules. These bonds create a strong attraction, causing water molecules to stick together. This phenomenon results in high surface tension, allowing some insects to walk on water and water droplets to form beads. Cohesion also contributes to the movement of water through plants, as it enables water to be pulled up the plant's vascular system against gravity in a process called transpiration.
Adhesion, in the context of water, refers to the attraction between water molecules and other substances, such as the walls of a narrow tube. This property allows water to climb up thin tubes, even defying gravity, through capillary action. This process is seen in plants, where water is drawn up from the roots to the leaves, providing essential nutrients. Both cohesion and adhesion play vital roles in water's movement and distribution in the natural world.

The sentences below contain one advantage statement and one disadvantage statement. To form a strong basis for debate, both statements must be true and both statements must make valid points.
Which statements best debate the advantages and disadvantages of using renewable energy sources, such as hydropower, solar energy, or geothermal resources?
Choose the correct answer.
Solar energy is extremely inexpensive to harvest. Solar energy is available everywhere on the planet.
The use of geothermal energy produces enormous amounts of pollution. The technology required to collect thermal energy is relatively inexpensive.
Geothermal energy is more renewable than solar energy. Hydropower can change flowing water from a renewable energy resource to a nonrenewable resource.
The use of hydropower requires the construction of dams that change the ecology of the river. Hydropower will be available as long as the river continues to flow.

Explanation:
A DNA molecule with a total of 1500 nucleotides has 300 cytosines. How many thymines does the DNA molecule have?
The DNA molecules will have 450 thymines if a DNA molecule has a total of 1500nucleotides
A DNA molecule also known as deoxyribonucleic acid is made up of a double helix.
The DNA molecule with a total of 1500 nucleotides will contain 750 cytosine and Thymines and 750 guanines and adenine.
Hence we can have the expression:
C + T = 750
If there are 300 cytosines, hence;
300 + T = 750
T = 750 - 300
T = 450
This shows that the DNA molecules will have 450 thymines

Why don't the hydrolytic enzymes Within lysosomes destroy each other?
Answer:
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
