does anyone know the answer to this?

Answer:

three types of stimuli—mechanical, thermal, and chemical; some endings respond primarily to one type of stimulation, whereas other endings can detect all types. Chemical substances produced by the body that excite pain receptors include bradykinin, serotonin, and histamine.

Explanation:

Answer:

In a population, more individuals are born than can survive. The available resources in nature are finite (food, water, space, etc.) and the environment is not able to support unlimited growth of a population. This causes an inevitable struggle for existence among individuals (continual struggle for existence).

➜ Mendel conducted breeding experiments with garden peas:

[i] He studied plants (pure) of a tall/short varities.

[ii] He crossed them and obtained F1 progeny.

[iii] He found that F1 progeny was all tall plants.

[iv] He selfed the (hybrid) plants if F1 progeny.

[v] He found that in F2 progeny there were tall as well as short plants.

[vi] The three quarter plants were tall and one quarter was short.

(or any other contrasting character may be taken).

Note: Here, F1 means First fillial generation and F2 means Second fillial generation.

Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. ... Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants...We used to take this character, we may choose different.

Explanation:

Answer: Not all cells move through the cell cycle at the same rate. Proteins that regulate the timing of the cell cycle. Most of the differences in cell cycle duration between species and cells are found in the duration of specific cell cycle phases. DNA replication, for example, generally proceeds faster the simpler the organisms.

Answer:

It provides more surface area for the absorption of oxygen.

Explanation:

The advantage of lungs with alveoli compared to lungs without alveoli is the availability of large surface area for the oxygen absorption. Alveoli allows oxygen from the air to pass into your blood. There are 480 million alveoli are present in human lungs, this large number and small size of alveoli provides lungs a large surface area to volume ratio so we can conclude that the lungs work better with the help of alveoli as instead of lungs without alveoli.

Answer:

Option C us correct.

km • m/S

Explanation:

This is because momentum is result of mass and velocity of an object. Momentum is a vector quantity that is it has magnitude and it's direction is in form of three dimensional.

From the option C, kilometer there is not a unit for mass or velocity it it is a unit for distance, therefore it is incorrect.

Answer:

the last option is the answer

Answer:

Answer:

A. Saprotroph

Explanation:

A saprotroph is described as an organism that gains nourishment from organic matter that has started to decay.

As per the situation, the organism that grows on dead trees, consuming the detritus left by another decomposer are saprotroph.

Saprotroph, also called saprophyte or saprobe, are organism that grazes on the nonliving organic matter known as debris at a microscopic level.

Bacteria, fungi, etc are examples of saprotrophs.

Thus, option "A" saprotroph.

Answer:B

Explanation: I took this test

One copy of the gene may mutate further and begin to function differently from the original  is the most plausible way that this mutation may eventually benefit the species.

A mutation is a change to an organism's Genetic sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.

Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.

Our cells constantly undergo mutations, yet surprisingly few of these have an adverse impact on our health.  A mutation is never so advantageous in real life.

Therefore, One copy of the gene may mutate further and begin to function differently from the original  is the most plausible way that this mutation may eventually benefit the species.

Explanation:

Cellular respiration is a chemical process which breaks downs a 6 carbons compound into 3 carbon dioxide molecules and water molecules in the presence of oxygen and produces a huge amount of energy in form of ATPs.

Cellular respiration is a chemical process which breaks downs a 6 carbons compound into 3 carbon dioxide molecules and water molecules in the presence of oxygen and produces a huge amount of energy in form of ATPs.

In the presence of oxygen, cellular respiration is a chemical process that converts a substance with six carbons into three carbon dioxide and water molecules and enormous amounts of energy in the form of ATPs.

Simply put, cellular respiration is a sequence of metabolic processes that happen inside a cell. For usage in the energy-demanding processes of the cell, biochemical energy is extracted from organic materials.

It is stored in energy-carrying biomolecules (such as adenosine triphosphate or ATP).

Therefore, Cellular respiration is a chemical process which breaks downs a 6 carbons compound into 3 carbon dioxide molecules and water molecules in the presence of oxygen and produces a huge amount of energy in form of ATPs.

True is your answer

Explanation:

An autosome is any of the numbered chromosomes, as opposed to the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes (the X and Y). ... That is, Chromosome 1 has approximately 2,800 genes, while chromosome 22 has approximately 750 genes

Answer: C

Explanation:

The folding of the protein determines the structure. Each polypeptide has a primary structure all the way up to quartenary structure which allows the protein to fold based on the R groups of the amino acids. If the structure of the protein is disturbed, it won't perform its proper function.

Answer:

The answer would be Hydrophobic tail and a hydrophilic head. Just some background info, this is located in the cell membrane and the cell membrane is made of up something called the Lipid Bilayer. The word "bi" means 2, so it comprise of 2 layers of phospholipids. These 2 layers of phospholipids are called hyrodrohpbic and hydrophilic. The word "phobic" means fear, so they hydrophobic molecules are NOT attracted to water. Hydrophilic molecules, however, ARE attracted to the molecules.

Answer:

Increased carbon dioxide means increased blood acidity, while decreased carbon dioxide means increased blood acidity.

The bicarbonate reaction is reversible, which allows bicarbonate to turn back into dissolved carbon dioxide to diffuse from the alveolus.
