The force driving simple diffusion is _____, while the energy source for active transport is _____.
a. the concentration gradient; atp
b. phosphorylated protein carriers; atp
c. the concentration gradient; adp
d. transmembrane pumps; electron transport and. atp; phosphorylated proteins.

Answers

Answer:

The answer is A. The force driving simple diffusion is the concentration gradient, while the energy source for active transport is ATP.

Explanation:

For simple diffusion, the movements of solutes and solvents depend on the electrochemical gradient. Usually, there are no difficulties for this kind of diffusion as they can pass freely through the semi-permeable membrane. This includes water, oxygen, carbon dioxide, etc. To demonstrate, we put a glass of water with sugar particles in it and a semi-permeable barrier in between, with the left side having MORE sugar. Equilibrium must always be attained in this kind of reaction. So the water (solvent) will pass through the membrane, right to left, from a higher concentration to lower concentration of water, to attain equilibrium. This doesn't require ATP or energy to occur.

For active transport, ATP will always be utilized to occur. An example would be the Na+/K+ pump. In order to maintain equilibrium, these ions are supposed to travel in and out of a cell. But moving from a low concentration to a high concentration area is difficult without a pump and ions are too big to pass through the semi-permeable membrane. So that's why they utilize this kind of transport.

Final answer:

The force driving simple diffusion is the concentration gradient, while the energy source for active transport is ATP.

Explanation:

The force driving simple diffusion is the concentration gradient, this means that particles will move from an area of higher concentration to an area of lower concentration. On the other hand, active transport is a process that moves particles from an area of lower concentration to an area of higher concentration. This process is against the concentration gradient and requires an energy source. The main source of this energy is ATP (Adenosine Triphosphate), a molecule that stores and provides energy necessary for intracellular activities. Hence, the correct answer is (a) concentration gradient; ATP.

How does the cell membrane aid the cell in maintaining homeostasis?

6.png

The cell membrane uses energy to remove waste products from the cell through sac-like packages.
The cell membrane extracts energy from food when the cell is low on energy.
The cell membrane controls all cellular activities in response to changes in the external environment.
The cell membrane assists with maintaining the correct temperature by absorbing energy.

Answers

The cell membrane helps a cell maintain homoeostasis by regulating the movement of substances in and out of the cell. The cell membrane is a lipid bilayer which is selectively permeable to substances.

The cell membrane controls all cellular activities in response to changes in the external environment. So the correct option is C.

What is the cell membrane?

All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell. Another is that there will be proteins on the cell's membrane, which is its plasma membrane, that interact with other cells.

These proteins may be lipid proteins, which include both a protein and a fatty acid, or they may be glycoproteins, which contain both a protein and a sugar moiety. Similarly, those proteins that adhere beyond the plasma membrane enable cell-to-cell communication. Additionally, a cell's membrane offers some structural support.

Also, various cell kinds have different types of plasma membranes, and the lipid component of the plasma membrane generally contains a lot of cholesterol. This is distinct from a few other membranes found inside the cell. There are several plants and microorganisms, such as bacteria and algae, that have various defense systems.

Therefore the correct option is C.

How has the study of mitosis affected scientists’ knowledge of cancer?
It led to a study of how to induce cancer cells to divide more rapidly.
It led to an understanding of how cancer cells divide so rapidly.
It led to the development of contact-inhibition regulators.
It led to the discovery of how to prevent cancer cells from dividing.

Answers

The right answer is It led to an understanding of how cancer cells divide so rapidly.

A cancer (or malignant tumor) is a disease characterized by an abnormally large cell proliferation (tumor) in a normal tissue of the body, so that the survival of the latter is threatened.

Control points are programmed between each phase of the cell cycle to verify that the current process is proceeding normally.

This is an opportunity for the cell to identify the occurrence of possible abnormalities in its cell cycle and to trigger either an action of correction of these errors or its self-destruction (apoptosis).

If these errors are not repaired, they accumulate. It is this accumulation, over time, that is at the origin of cancer. It is considered that it takes about ten mutations for the phenomenon of cancerization to appear.

The anomalies that occur are genetic mutations, caused by errors during the replication - or reproduction - of the DNA, and therefore of the genes, when the cell divides.

In the majority of cases, these mutations occur on the DNA of a somatic cell of a particular tissue, for example, on the DNA of a colon cell.

It led to an understanding of how cancer cells divide so rapidly. Therefore, option (B) is correct.

Mitosis has helped scientists understand how cancer cells rapidly divide uncontrollably. Cancer is characterised by unregulated cell proliferation, which can result from mitosis disruption. Scientists have discovered cancer cell growth pathways and signalling networks by studying mitosis.

This understanding has helped discover cancer therapy targets and design medications that disrupt cancer cell division to reduce development and spread. Other choices may be relevant to cancer research, but they don't directly answer how mitotic research has changed cancer research. Therefore, option (B) is correct.

In order to give the best response to this question, the data or the information that was given at the start of the question needs to be provided. Making the data attached would help us to make the best answer and not make an educated guess as this would be impossible.
Final answer:

The characteristic "friendships have mutual involvement" is not directly tied to the monetization of social networks, as monetization strategies often rely on aspects like user engagement, advertising, and network effects rather than individual relationship dynamics.

Explanation:

There are several characteristics needed to monetize social networks, but not all the features mentioned are directly tied to their monetization. When it comes to monetizing social networks, aspects such as user engagement, network effects, advertising capabilities, and payment infrastructures often play crucial roles. Characteristics like "instant communication", "fosters a sense of interconnectedness", and having "a large user base" (network effects) are fundamental. However, friendships have mutual involvement is not typically considered a characteristic required to monetize social networks.

While interpersonal connections and community building are important for social networks, they are not direct monetization strategies. Instead, these networks monetize through advertising, subscription models, or transaction fees, which rely more on broad user engagement and data rather than on individual relationships. Therefore, the statement that friendships require mutual involvement does not directly apply to the monetization of social networks but rather speaks to the quality of interpersonal interactions within these platforms
