Answer:

C.

Explanation: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Hope this helps! Have a nice day!

Answer:

C. to produce a new cell

Explanation:

Mitosis consists in replicating the genetic material of a mother cell in order to make two identical daughter cells; this is a diploid process. In order to make an egg or sperm cell and eventually a new organism, the correct process would be meiosis, since it combines the DNA between two cells and it is an haploid process.

Answer:

C. a dog buries a bone in the backyard

Explanation:

A dog burying a bone in the backyard is not an observation in terms of scientific methods.

Observation is the process of acquiring data about a phenomenon under study.

Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.

Also, we can use some specialized equipment to make observations.

How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?

by increasing carbon dioxide and decreasing oxygen

by increasing carbon dioxide and increasing oxygen

by decreasing carbon dioxide and increasing oxygen

by decreasing carbon dioxide and decreasing oxygen

The answer to this question is by increasing carbon dioxide and decreasing oxygen.

Explanation:

Rainforests have a vital role on Earth because these regulate the levels of oxygen vs carbon dioxide. This is because plants including trees, grasses, shrubs, etc. require carbon dioxide as part of the photosynthesis process, and they release oxygen at the end of the process. In this way, rainforests reduce the amount of carbon dioxide and increase oxygen.

In this context, deforestation or the destruction of rainforest for mining, roads, etc. implies there are fewer plants, and therefore, less carbon dioxide is being used and less oxygen is released. This causes an increase in carbon dioxide and a decrease in oxygen.

Answer:

The principal disadvantage of monogamy is a lack of variety. Monogamy has the potential to lead to routine, and possibly boredom. People often equate excitement in a relationship with the ability to be with a number of individuals, potentially as part of an open or sometimes polyamorous relationship.

Explanation:

Answer:

C

Explanation:

Prokaryotic cells do not have any membrane-bound organelles, only eukaryotes do.

The prokaryotic cell is a simple primitive cell, unlike the complex eukaryotic cells. The absence of a membrane-bound nucleus is a characteristic of prokaryotes. Thus, option C is correct.

Prokaryotes have been the cells that have lived on earth for millions of years ago. They are made of single cells and hence are unicellular. Unlike the eukaryotic cell, they have simple mechanisms of living and reproduction.

They lack a centrally located defined nucleus that is not covered in any membrane and lies simply in the cytoplasmic material. Also, they lack organelles that make them different.

The genetic material is located in a concentrated form in a structure called the nucleoid that lacks a nuclear membrane.

Therefore, option C. the prokaryote lacks a membrane-bound nucleus.

The difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill will be described as after starting off much more slowly, it picks up speed significantly by the bottom of the slope.

At the top of the hill, a sled has pushed itself. If we then apply a tiny push, the sled's initial speed will be 0, indicating that the sled's only starting energy is gravitational potential energy. Therefore, assuming there is no friction, the sled's greatest height will be equal to its initial brightness. So the slides will never make up for a bump that is higher than its starting point. The sled's highest point is equal to its initial height because of the rule of conservation of mechanical energy. The sled will never make it up if they restrict it if the friction is seated.

The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.

Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.

Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.

Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.

Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.
