The ocean surface removes carbon from the atmosphere through diffusion is an example of respiration.
What do you mean by diffusion?Diffusion is the net movement of anything generally from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in Gibbs free energy or chemical potential.
One of the main characteristics of diffusion is the movement of molecules along the concentration gradient. While this could be facilitated by other molecules, it does not directly involve high-energy molecules.
The three types of diffusion are - simple diffusion, osmosis and facilitated diffusion.

8. The TP53 gene is a tumor suppressor gene that encodes for p53 proteins. This protein plays an active role in
identifying DNA damage in the G1 checkpoint and determining if the damage can be fixed. If the damage can
be fixed, the p53 protein activates other genes for the repair. If the damage cannot be fixed, the p53 protein
prevents cell division and signals for apoptosis. What is most likely to happen to a cell with a mutated TP53
gene?

During the cephalic phase of gastric secretion... A. thinking about, seeing, and smelling food reflexively increases gastric secretion B. vagal stimulation of the gastric glands occurs C. gastrin is released D. chewing food reflexively increases gastric secretion E. Both Band C are correct F. Both C and D are correct G. A, B, C, and D are correct
The complete question is:
What does NOT happen during the cephalic phase of gastric secretion?
a. Thinking about, seeing, smelling, and chewing food reflexively increases gastric
secretion.
b. Vagal stimulation of the gastric glands occurs.
c. Secretin is released.
Answer:
C). Secretion is released.
Explanation:
As per the question, the 'secretion releasing' does not take place throughout the cephallic phase pertaining to gastric secretion. During this phase, the food passes into the stomach while eating. This occurs causes acid secretion which is the response to the appetite stimulation caused by our senses like sight, smell, etc. Thus, option C is the correct answer.
This increase in the plant cell as water moves in keeping the plant erect but prevents it from bursting. A. Exocytosis
B. Gradients C. Turgid pressure D. Diffusion
Answer:
The change is caused by C. Turgid pressure
Explanation:
Turgor pressure, is exerted internally by the plants own cells. The water in the plant moves from areas of high concentration to areas of low concentration along a concentration gradient.
The cells contain large organelles called vacuoles, which are filled with water, salts and other substances contained in cell sap. The large vacuole takes up most of the cell, and pushes against the cell walls. This exerted pressure keeps the cell's shape, and ensure that the tissues stay upright.

Explanation:
Describe what happens in the 5 stages of cell replication.
Mitosis is a process of cell division, whereby a single cell divides into two genetically identical daughter cells. The five stage of mitosis are interphase, prophase, metaphase, anaphase and telophase.
1. Interphase:
The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?.
Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.
During interphase, microtubules extend from these centrosomes.
2. Prophase:
The chromosomes condense into X-shaped structures that can be easily seen under a microscope.
Each chromosome is composed of two sister chromatids, containing identical genetic information.
The chromosomes pair up so that both copies of chromosome 1 are together, both copies of chromosome 2 are together, and so on.
At the end of prophase the membrane around the nucleus in the cell dissolves away releasing the chromosomes.
The mitotic spindle, consisting of the microtubules and other proteins, extends across the cell between the centrioles as they move to opposite poles of the cell.
3. Metaphase:
The chromosomes line up neatly end-to-end along the centre (equator) of the cell.
The centrioles are now at opposite poles of the cell with the mitotic spindle fibres extending from them.
The mitotic spindle fibres attach to each of the sister chromatids.
4. Anaphase:
The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.
5. Telophase:
At each pole of the cell a full set of chromosomes gather together.
A membrane forms around each set of chromosomes to create two new nuclei.
The single cell then pinches in the middle to form two separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis.

The basic process of disease transmission involves:_________
a. a source, a mode of transmission, and a susceptible host.
b. a highly virulent pathogen and a breakdown in infection control techniques.
c. a source, a weakened host immune system, and delayed recognition of the infection.
d. poor hand washing, a susceptible host, and inappropriate antibiotic us
Answer:
The basic process of disease transmission involves:_________
a. a source, a mode of transmission, and a susceptible host.
Explanation:
The sources of a disease include individuals, animals, and the environment. Transmission occurs when there is a transfer of the pathogen from one individual or source to another. Disease transmission cannot be complete without the host. As always, a successful transmission happens when the host becomes susceptible to the disease, which will weaken its immune system.
Can the epidermis bleed?

Why does controlling transcription affect prokaryotic gene expression?
Answer:
However, a lot of gene regulation occurs at the level of transcription. Bacteria have specific regulatory molecules that control whether a particular gene will be transcribed into mRNA. Often, these molecules act by binding to DNA near the gene and helping or blocking the transcription enzyme, RNA polymerase.
Explanation:
Plz mark brainliest thanks
Controlling transcription effect prokaryotic gene expression as when the resulting protein is no longer needed, transcription stops.
What is prokaryotic gene expression?Transcription is the primary control point for prokaryotic gene expression. At the levels of epigenetics, transcription, post-transcription, translation, and post-translation, eukaryotic gene expression is regulated.
Due to the lack of a clearly defined nucleus, prokaryotic gene expression takes place within the cytoplasm of a cell; as a result, the DN is freely located within the cytoplasm. Eukaryotic genes are expressed in the cytoplasm and nucleus, respectively.
These molecules frequently work by attaching to DNA close to the gene and assisting or inhibiting the RNA polymerase transcription enzyme.
Therefore, specific regulatory molecules in bacteria determine whether a given gene is translated into mRNA.

The oceanic water is salty as they have salts mixed in it.
The correct option is C.
70% of the earth is made up of water and most of the water is salty due to the leaching process of salt during the formation of the earth.
In that time rain pours on earth for millions of years which digested the rock and dissolves its nutrient.
Hence, the correct option is C that is warm water with high salt content. The salt concentration remains the same throughout the water.

The air in the thermosphere becomes thinner and thinner until it fades into space. true or false
Answer: hope this helps
Explanation: The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. The temperature increases rapidly in this layer due to the absorption of huge amounts of incoming high energy solar radiation by atoms of nitrogen and oxygen.
The air in the atmosphere becomes thinner and thinner until it fades into the space because thermosphere has less air pressure and gases.
What happens in thermosphere ?A layer (or layers) of gases that surround a planet and are held in place by the gravity of the planetary body is known as an atmosphere.
The air at the bottom of the atmosphere is under much more weight than the air nearer the top, like the acrobat at the bottom of a stack of acrobats. It follows that the air closer to the Earth's surface is compressed by the air above it and is subsequently denser. The air gets thinner as you go higher in the atmosphere.
Therefore, as we go further into the space the thermosphere becomes thinner and thinner until it fades into space.
