Answer:

Autocrine:Autocrine signaling means the production and secretion of an extracellular mediator by a cell followed by the binding of that mediator to receptors on the same cell to initiate signal transduction. A well-characterized form of autocrine signaling is the secretion of IL-1 by macrophages.

Juxtacrine:In biology, juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact. ... A membrane ligand (protein, oligosaccharide, lipid) and a membrane protein of two adjacent cells interact.

Endocrine:The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.

Paracrine:Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells. ... However, the exact distance that paracrine factors can travel is not certain.

Answer:

Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils. In phenolphthalein, indicator acids remain colorless, and base gives pink color.

Explanation:

An acid is a substance that releases hydrogen ions into an aqueous solution. A base is a substance that releases hydroxide ions.

Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils. In phenolphthalein, indicator acids remain colorless, and base gives pink color.

source of pergisol

Explanation:

What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.

Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.

Explanation:

Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again. So I think false

Answer:

Hydrogen and oxygen molecules

Explanation:

Answer:

Plants need water, so that their guard cells can fill up and become turgid which would allow the stomata to open and gas to exchange. If there is not much water, not much gas exchange can occur hence not much Carbon dioxide can be taken in.

Explanation:

Plants require water for the process of photosynthesis. Plants need water so that their guard cells can fill up and become turgid. This allows the exchange of gases in the stomata.

During photosynthesis, the plants take in carbon dioxide and water molecules from the air and soil particles. Within the plant cell, this water is oxidized to generate oxygen gas, meaning that it loses electrons, while the carbon dioxide gas is reduced in the chloroplast of the plant cell by gain of electrons to produce carbohydrates. This process transforms the water into oxygen gas and the carbon dioxide gas into glucose molecules (carbohydrates).

Plants need water, so that the guard cells in the plant can fill up and become turgid which would allow the stomata to open and exchange of gases. If there is not much water present in the guard cells, not much gas exchange can occur hence not much of the carbon dioxide can be taken in from the atmosphere.

Explanation:

Answer:

I think its C but I am not sure, I hope this helps :)

Explanation:

The statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Diffusion (both facilitated diffusion and simple diffusion) refers to the movement of substances across biological membranes from an area of high concentration to an area of low concentration.

Facilitated diffusion and simple diffusion are two types of passive transport that do not require energy to move molecules/ions in favor of a concentration gradient.

In facilitated diffusion, specific membrane proteins known as carriers or channels help to the movement of substances in favor of a concentration gradient.

Conversely, in simple diffusion, small molecules (e.g. CO2 and oxygen) freely diffuse across a selectively permeable membrane in favor of a concentration gradient.

In conclusion, the statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Answer:

Incomplete dominance

Explanation:

The inheritance pattern described here is called incomplete dominance (sometimes also referred to as semi-dominance or partial dominance). This occurs when the dominant allele doesn't fully prevent the effects of the recessive allele from being expressed. This results in the trait of the offspring being equivalent to the mix of both alleles. If the rooster's feathers are black and the hen's are white, the chicks' will be grey.

Answer:

32 chromosomes (16 pair)

Explanation:

Gametes or sex cells of sexually reproducing organisms are produced via a process called MEIOSIS, which is a type of cell division that reduces the chromosomal number of the parent cell by half. Hence, a mice that produces a sperm cell (gametes) via meiosis with 16 chromosomes will have double that amount in somatic cells of that mouse.

That is, the expected number of chromosomes in an adult mouse of this species with 16 chromosome in its sperm cell is 32 since half of this number makes up the chromosomal number in gametes
