At a neuromuscular junction Group of answer choices neurotransmitters are released. actin and myosin filaments slide past one another. intercalated discs are synthesized. troponin and tropomyosin exchange places.
Answer:
Neurotransmitters are released
Explanation:
At a neuromuscular junction, action potential that arrives there causes the release of the acetylcholine into the synapse. This then binds to the receptors that span across the surface of the motor end plate triggering muscle contraction with the release of calcium.
It acts as a transmission passageway for action potential between the end of a motor nerve and a muscle.
what are chloroplasts? why are they green? how is the green colour plant of a great importance to the whole living world? explain?
Answer:
Chloroplasts are structures found in the cytoplasm of plant cells that are the site for photosynthesis. They are green because they contain a pigment called chlorophyll. Chlorophyll absorbs light to bring about the photosynthesis reaction. Light energy is crucial to initiate photosynthesis.
Photosynthesis allows the plant to convert carbon dioxide from air and water absorbed from the roots into oxygen and glucose, which are foods for plants. By releasing oxygen to air through photosynthesis, other living things can breathe in oxygen so that energy can be generated through another process, called respiration. Respiration is like the reverse reaction of photosynthesis, but it turns glucose to energy that supports living things.
Because plants also respire to generate energy, by using the glucose produced from photosynthesis, it also supports the food chain in the living world. Other organisms can consume plants for their energy.
In the end, chloroplasts and the chlorophyll inside are very important to the living world.
what converts solar energy (sunlight) into chemical energy through photosynthesis

If your blood becomes too concentrated with ions, what will happen to the red blood cells?
A. They undergo crenation.
B. They become turgid.
C. They undergo lysis.
D. They absorb some of the ions to balance the concentration.
The correct answer is option A. They undergo crenation.
What if red blood cells are placed in a hypotonic solution?When red blood cells are placed in the hypotonic solution, there is a net movement of free water into the cells. In this situation, the intracellular solute concentration is low and the intracellular volume is increased. The total solute concentration of the solution will be high.
When red blood cells are in a hypertonic (high concentration) solution, water exits the cell faster than it enters the cell. This leads to the creation (contraction) of blood cells.

What usually happens to the host’s DNA during the lytic cycle? It is destroyed. It is integrated with the viral DNA. It becomes a provirus. It is deactivated.
Answer:
It is destroyed
Explanation:
The lytic cycle of the viral life cycle is characterized by the destruction of the host's DNA. The infecting phage gains entrance into the host's cell synthesizes proteins that break down the host's DNA, and then utilizes its own DNA as the cellular DNA.
From there on, the phage takes over the cell's genetic mechanisms and utilizes it in the synthesis of the necessary proteins to manufacture new infecting structures.

Which of the following types of reproductive barriers separates a pair of insect species that could interbreed but for the fact that one lives on goldenrod plants and the other on autumn daisies in the same general area?
a) habitat isolation
b) gametic isolation
c) behavioral isolation
d) temporal isolation
Answer:
The correct answer is - option A.
Explanation:
Reproductive barrier is a biological difference between two species that do not allow them to interbreed. Type of reproductive barrier is decided by the trait or barrier that prevents them to interbreeding.
habitat isolation takes pace when the prezygotic barrier that prevents interbreed two species due to the fact that they live in different area as insects that lives in golden rod and autumn daisy have different habitat.

The reproductive barrier is defined as the biological isolation between two species that prohibits them to interbreed.
The correct answer is:
Option A. Habitat isolation
Habitat isolation can be defined as:
Habitat isolation is defined as a type of reproductive barrier that prevents the interbreeding between the organisms. Habitat isolation does not mean that the organisms living in different areas are unable to reproduce. The organisms living in the same geographical area but unable to interbreed because one of them lives on goldenrod plants and the other on autumn daisies is referred to as habitat isolation.

The wells that contain the DNA samples are placed next to the negatively charged electrode in the electrophoresis box (chamber) because _______. Group of answer choices DNA strands have both a positive and a negative charge DNA is negatively charged DNA is positively charged DNA has no electrical charge
Answer:
DNA is negatively charged
Explanation:
Electrophoresis: In biology, the term "electrophoresis" is described as one of the different laboratory technique that is being utilized to separate protein molecules, DNA, and RNA one the basis of their electrical charge and size. Therefore, a specific amount of "electric current" is being used to move different molecules that are required to be separated through a "gel". The given gel contains pores that generally works like a "sieve" and thus allows every small molecule to proceed faster as compared to the larger molecules.
DNA stands for "deoxyribonucleic acid" is determined as a long molecule that ought to contain an individual's unique "genetic code" and generally carried information associated for making proteins in an individual's body.
In the question above, the correct answer is "DNA is negatively charged".
The samples of DNA are placed next to the negatively charged electrode in the electrophoresis as DNA is negatively charged.
What is electrophoresis?It is a laboratory technique, which is used to distinguish RNA, DNA or molecules of protein on the basis of their electrical charge and size. In the process, an electric current is utilized to move molecules to be separated via a gel. The gel comprises pores that functions as a sieve, which permits smaller molecules to move faster in comparison to larger molecules.
DNA is a negatively charged molecule, thus, when it is used in the process of electrophoresis, the migration of DNA will take place towards the positively charged electrode. Through the gel, the DNA with shorter strands will move more briskly in comparison to the longer strands leading to the formation of fragments being aligned in order of size.
Thus, the samples of DNA are placed next to the negatively charged electrode as they are negatively charged.

The rate of a reaction catalyzed by an enzymes usually ________ with temperature; however, at temperatures above the optimum range ________. The rate of a reaction catalyzed by an enzymes usually ________ with temperature; however, at temperatures above the optimum range ________. decreases; prosthetic groups are necessary increases; protein denaturation occurs decreases; the reaction proceeds without the enzyme increases; the reaction proceeds without the enzyme increases; the direction of the reaction reverses
Answer:
increases; protein denaturation occurs
Explanation:
One of the characteristic of enzymes is the sensitivity to temperature .
Enzymes are sensitive to the changes in the environmental temperature.The enzymatic activities increases with increase in temperature,up to the optimum of 37 degrees in most animals.
However,once the optimum temperature has been exceeded,enzyme activities drops.This is because below optimum the rate of collision between the enzyme active sites and substrate molecules is very high,therefore more products are formed which increases the rate of reactions.
At temperature above the optimum,the high temperature breaks the bonds,especially the hydrogen bonds holding the 3D structure of the active sites.Therefore,substrate molecules can not fit into the active site,and therefore enzymatic actives of the enzyme is affected,and the enzyme is said to be denatured

b) Mendel's law of segregation
c) Darwin's explanation of natural selection
d) Darwin's observations of competition
e) The malarial parasite changing the allele
Answer:
The correct option is C.
Explanation:
According to Darwin's Law of Natural Selection, a gene that benefits the organism and helps it produce healty offspring so that it can survive is supported by natural selection and will receive a positive feedback over.
The fact that the heterozygosity for sickle cell anemia helps with the survivability of malaria, which is a deadly disease, suggests that the heterozygosity is favored by the law of natural selection.
