explain the roles of mRNA and tRNA in protein synthesis
Answer:
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis

Question 1(Multiple Choice Worth 2 points)(05.05 MC)How does the human immune system initially respond to a pathogen?
Immediately, the pathogen has been recognized:
Macrophages acts as the first line of defence by engulfing pathogens identified by antigens which will now present the antibody shape to a helper T cell.
The Helper T cells produce a signal to plasma and Memory B cells to yield antibodies that attach to the antigens. The cytotoxic cells that leads to cell death are activated by the helper T cells.
Antibodies helps to immobilize pathogen for macrophage to feed on.
if the pathogen comes back a 2nd time the memory cells helps in quick and efficient recovery by producing the specific B and T cells for the antigen.

What are coral reefs?A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Coral reefs are massive structures made of limestone deposited by coral polyps. Often referred to as the “rainforests of the sea,” coral reefs support approximately 25 percent of all known marine species.
Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point) Both are balanced according to the total mass before and after the change. A chemical equation is balanced according to mass number. A nuclear equation is balanced according to the total mass before and after the change. Both are balanced according to the mass number of each element before and after the change. A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.
Both nuclear and chemical equations are balanced according to the total mass before and after the change.
In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.
Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.
More on the law of conservation of mass can be found here: https://brainly.com/question/13383562
Answer:
A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.
Explanation:
Both equations are not balanced according to the total mass.
What are proteins composed of, and what are their main functions in the body
Answer:
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.
Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains.
Explanation:
in the overall reactions of photosynthesis, the electrons from _____ are used to reduce _____.
In the overall reactions of photosynthesis, the electrons from water are used to reduce carbon dioxide.
During photosynthesis, electrons from water molecules are used to reduce carbon dioxide and fix it into carbohydrates while oxygen is produced as a result. The process happens with the help of radiant energy.
Even though the process of photosynthesis is a series of reactions that have been divided into light-dependent and light-independent, the overall equation of the process is written as:
[tex]6H_2O + 6CO_2 ---> C_6H_1_2O_6 + 6O_2[/tex]

the two proteins directly involved in muscle contraction are broadly called
The two proteins directly involved in muscle contraction are MYOSIN AND ACTIN. The interaction between these proteins is responsible for muscle contraction.
The sarcomere is the basic unit of muscle cells (myofibrils) that mediate muscle contraction both in skeletal and cardiac muscle tissue.
During muscle contraction, myosin and actin proteins slide past each other, thereby leading to sarcomere shortening.
The myosin protein binds to actin filaments and thus myosin acts as a motor protein that drives filament sliding.

true or false? to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax
The thorax is a very vital and important organ in the human body.
It is a structure that serves as a protective covering for organs in the body such as the lungs, the heart, some vital blood vessels e.t.cIt is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.
When a person breathes in, the chest cavity expands (the volume increases) and the pressure in the thorax decreases. When a person breathes out, the chest cavity decreases in size, and the pressure in the thorax increases. Therefore, we can see that the process of breathing in humans, follows the principle of Boyle's Law. Boyle's law states that as the volume increases there is a decrease in pressure and as the volume decrease there is an increase in pressure.Therefore, It is false that to make a person breathe in, the volume of the chest cavity must decrease, creating a higher pressure in the thorax.
