Are there any mammalian cells that would be a good source for dividing cells? What types of cells would most like NOT have cells undergoing division?
Answers
Answer:
Skin cells, bone cells
Explanation:
1. Skin cells are constantly being replaced, so it's likely they will be undergoing Mitosis.
2. Bones grow very slowly, and can last for years, which means that it's unlikely they will be undergoing mitosis.
There are a couple of mammalian cells that would be a good source for dividing cells. They include but not limited to:
The cells of the skinCells in the bone marrowThe cells of the skin adjacent to the environment are constantly being replaced by cell division due to death relating to environmental factors.
The cells in the bone marrow are also dividing constantly because old blood cells are constantly being replaced.
Some cells in the human body do not divide ordinarily, unless they are called upon to do so on special circumstances. For example, the cells of the heart stop dividing once the heart gets to a particular size. The cells enter the quiescent stage of the cell cycle and they are only called upon to divide in case an injury occur to the heart and it needs to repair itself.

Answers
Answer:
Independent variable: amount of insecticide
Dependent variable: effects of insecticide on frogs
Explanation:
Dependent variable in a research experiment, is the variable that is being studied, tested and measured by the researcher, while the independent variable is the variable that causes the dependent variable to change, when it is varied.
In this case, the amount of insecticides that is varied in quantity, is the independent variable that the researcher manipulates, while the independent variable is the effects caused by these varied amount of insecticide on frogs, which is tested and measured.

Answers
Answer:
The pickup truck is the only vehicle accelerating.
Explanation:
Acceleration refers to the change in velocity per unit time which means that when the velocity changes, acceleration will be produced and if there is constant velocity of a vehicle so the acceleration will be zero. All three vehicles have same velocity of 15 m/s but the truck has no uniform velocity which means acceleration is produced in the truck while no acceleration is formed by three vehicles.
Answer:

What characteristic of viruses distinguishes them from cells? They lack an independent metabolism. Their traits do not evolve in response to selection pressures. They are not separated from their environments. They do not have hereditary material.
Answers
Answer:
The correct answer is "They lack an independent metabolism"
Explanation:
Viruses are usually active/alive in a living environment and become inactive in non-living environment; these is because they rely on the metabolic activities of the invaded living environment/cell. This property is a sharp contrast to normal living cells that are able to metabolize different substances independently using several organelles.

Please help! I suck at Science!
Answers
Answer:
A
Explanation:
because it is known as a large molecule
The starch molecule is known as a good source of energy for an organism because the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.
What is a Starch molecule?A starch molecule may be defined as a type of molecule that significantly consists of a chain of glucose molecules that are bound together in order to construct a bigger molecule, which is called a polysaccharide.
There are two types of polysaccharides present in the molecules of starch. They are as follows:
Amylose: It is a linear chain of glucose. Amylopectin: It is highly a branched chain of glucose.These long chains of glucose store a tremendous amount of energy during the synthesis of the starch molecules. Glucose provides instant energy while the breakdown of bonds in starch molecules takes time. So, the energy is liberated accordingly with a long-lasting effect.
Therefore, the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.

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?
Answers
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.

What process occurs in Box A?
a. A scheme of cellular respiration. At box A, which is located in the cytosol, glucose turns into pyruvate with release of ATP and electrons carried by NADH.
b. Pyruvate from this stage is used in a cycle in box B, which is located in the mitochondrion.
c. As a result, ATP, CO2, and electrons carried by NADH and FADH2 are released.
d. The electrons carried by NADH and FADH2 from boxes A and B are used in box C (inside the mitochondrion) for transformation of a substance marked D (that comes from the cytosol) into a substance marked E (released to the cytosol) with release of ATP.
Answers
Answer:
The process occurring in Box A is Glycolysis
Explanation:
Glycolysis is the pathway by which glucose, a six-carbon molecule is oxidized to molecules of pyruvate, a three-carbon molecule with the release of ATP and electrons which are carried by NADH molecules.
The process occurs in the cytoplasm of cells and requires 10 glycolytic enzymes.
The pyruvate molecules from glycolysis is first oxidized to acetyl-CoA and carbon dioxide molecules. The acetyl-CoA molecules enter the citric acid cycle occurring in the mitochondria and are used up in the production of ATP, CO2, and electrons carried by NADH and FADH2.
The electrons carried by NADH and FADH2 from glycolysis and citric acid cycle are used in the oxidative phosphorylation pathway occurring inside the mitochondrion for transformation of oxygen molecules into water molecules with release of ATP.

TONICITY:
Tonicity is the ability of a solution to induce movement of water in and out of a cell. Tonicity can either be hypertonic, hypotonic or isotonic in nature. Hypotonic solution is a solution that is lesser in solute concentration compared to the cellular solution while hypertonic solution is a solution that is greater in solute concentration compared to the cellular solution. This means that the glass of water with 20% salt is hypertonic (higher in concentration) to the cell containing 5% salt.Learn more about hypertonic solution at: https://brainly.com/question/8984839?referrer=searchResults
Why don’t we have a complete fossil record of all life that’s ever lived?

Answer:
Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions. Fossils must be exposed at Earth's surface to have a chance of being found. Fossils can be destroyed when rocks erode, melt, or change composition.
Explanation:
For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.

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
Answers
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.
