Answer:

The release of acetylcholine to muscle cell receptors triggers muscle contractions.

Explanation:

Answer:

The offspring has the same number of chromosomes as its mother and father.

Explanation:

The child shares the same number of chromosomes with both parents. Two parents participate in sexual reproduction, which results in children with distinct genetic makeup.

A diploid zygote is created during sexual reproduction when two haploid gametes combine during fertilization.

Asexual reproduction creates clones of the original parent, which results in kids that are genetically identical to the parent. Asexual reproduction allows for the rapid production of vast numbers of children by a single person.

This is due to the fact that in asexual reproduction, the only single parent produces an additional child that is genetically identical to the parent.

Therefore, the sexual mode of reproduction is seen to be superior to the asexual mode.

Yes, the ATP will be absorbed by your muscle cells and increase the amount of ATP within your muscles.

ATP is adenine triphosphate, which is an organic compound.

The role of ATP is to provide energy to carry out many functions of the living cells.

The ATP is made up of one adenine atom attached to nine carbon atoms and one sugar group.

The ATP is the energy source and if we drink, an energy drink, the ATP will go to the body.

Answer:

Sucrase is an enzyme that breaks sucrose down into glucose and fructose.

Explanation:

The bonds between the glucose and fructose molecules making up the disaccharide sucrose break due to the enzyme sucrase, and water is added as

H

and

OH

to the two molecules. This is called a hydrolysis reaction.

Hydrolysis is a chemical reaction in which water (hydro) breaks (lysis) a chemical bond in a dimer (two molecules bonded) and polymer (many molecules bonded) by adding

H

to one molecule and

OH

to the other molecule.

Answer:

Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

For most enzymes to operate in the body, the optimal temperature is 37 degree Celsius or 98 degrees Fahrenheit. Most of the human enzymes have a maximal activity at pH around 7.2, which is the pH of most body fluids. However, there are exceptions such as, pepsin.

The incorrect description is that Costal cartilages reinforce airways and support the external nose

The options were omitted but the complete question is :

Which description of skeletal cartilage is incorrect

Fibrocartilages are able to withstand both pressure and stretch.

Costal cartilages reinforce airways and support the external nose.

Elastic cartilages are able to tolerate repeated bending.

Articular cartilages cover the ends of most bones at moveable joints.

Costal cartilages are said to be at the anterior extreme of a rib cage. Their function is to give the ribcage a flexible structure and connect the ends of the ribs to the sternum. Respiratory cartilages are present in the Trachea and are responsible for flexible inhalation and exhalation thereby reinforcing airways and providing support to the structure of the nose.

The different photosynthetic plant pigments can be separated by PAPER CHROMATOGRAPHY. It is a methodology used to separate different chemical compounds based on their differential solubility.

This method (paper chromatography) uses paper sheets in order to separate mixtures of soluble substances such as, for example, plant pigments.

These paper sheets represent the 'stationary phase' through which a solution is made to pass.

Subsequently, during the mobile phase, the solvent moves through the paper sheet and thus carries (separates) different compounds with it.

Answer:

D. Which cell organelles carry out the process of photosyinthesis and cellular respiration?

Cellular respiration is the process which occurs in the mitochondria of organisms (plants and animal) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process generate carbon dioxide and water as waste products.

Photosynthesis is defined to as process by which green plants and certain other organisms transform light energy into chemical energy occurs in organelle chloroplast. Thus, the correct option is D which is which cell organelles carry out the processes of photosynthesis and cellular respiration?

Adenosine 5′-triphosphate, (ATP)  is an important “energy molecule” found in all life forms.  Mainly, it is a coenzyme which works with enzyme namely ATP triphosphatase to transfer energy to cells by releasing its phosphate groups.

Mitochondria is known as the power house of cell and chloroplast is organelle produce green colour pigment called chloroplast which help in photosynthesis.

The disturbance that causes the succession begins with a large whale dying and sinking to the bottom of the ocean floor. The whale carcass attracts scavengers and decomposers who eat the decaying meat.

Then, within a year, most of the whale's tissues have been eaten. The remainder of the carcass is then eaten by a much smaller number of fish. The decomposition of the whale's body will enrich the surrounding sediments with nutrients.

When only the skeleton is left, a third community moves in. Heterotrophic bacteria will begin to decompose the oils found inside whale bones. During this process, they will release chemical compounds that serve as energy sources for other bacteria. This chemosynthetic bacteria will also support a wide variety of nearby organisms living on the bones.

The decay of a dead whale on the ocean floor provides food and energy for a variety of organisms, which helps to maintain the equilibrium of the marine ecosystem.

When a whale dies, it sinks to the ocean floor and begins to decay. The decay process releases nutrients into the water, which attracts a variety of organisms, including bacteria, fungi, and worms. These organisms feed on the whale's carcass, breaking it down into smaller and smaller pieces.

As the whale decomposes, it releases carbon dioxide and other nutrients into the water. These nutrients are then used by other organisms in the ecosystem, such as algae and phytoplankton. The algae and phytoplankton use the nutrients to photosynthesize, which produces oxygen. The oxygen is then released into the water, which helps to support other life in the ecosystem.

The decay of a dead whale also provides a habitat for a variety of organisms. The whale's carcass creates a sheltered environment for small organisms, such as crabs and shrimp. These organisms provide food for larger organisms, such as fish and seabirds.

The decay of a dead whale is an important part of the marine ecosystem. It provides food and energy for a variety of organisms, which helps to maintain the equilibrium of the ecosystem. The decay process also releases nutrients into the water, which are then used by other organisms in the ecosystem.

Here are some additional details about the role of organisms in the decay of a dead whale:

The decay of a dead whale is a complex process that involves a variety of organisms. These organisms play an important role in maintaining the equilibrium of the marine ecosystem.
