3. Which of the following is a defining characteristic of a prokaryotic cell?
a. The method of cellular Respiration
b. The composition of the cell membrane
C. Absence of a membrane-bound nucleus
d. The method of movement
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.
What is a prokaryotic cell?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.

Why is it important for gametes to be haploid cells?
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.

explain how enzymes increase the speed of chemical reactions
Answer: Hey! So, enzymes are classified as biological catalysts. "Catalysts" tend to lower the activation energy for chenical reactions, and the lower the activation energy for a chemical reaction, the faster the rate! So, enzymes speed up reactions by lowering activation energy
Answer:
Lowering the activation energy.
What is endosymbiosis? How does the meaning of the root words “endo-“and“-symbiosis” help you understand the meaning of endosymbiosis?
Answer:
Endosymbiosis is a mutually beneficial relationship between a host organism and an internal associate organism. The term is derived from the prefix "endo," meaning within, and the word symbiosis, which refers to a mutually beneficial relationship between two closely associated organisms.

What is the purpose of Mitosis? *
A. To produce an egg and a sperm cell.
B. To produce a new organism (like bacteria).
C. To produce a new cell (NOT a new organism).
D. To differentiate.
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.

How would you describe the difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill?
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.

Rainforests around the world are being cleared at an alarming rate to make room for new communities, agriculture, mining, and roads, and to provide lumber for construction and furniture. How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
This question is incomplete because the options are missing; here is the missing section:
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.
