The answer is; B

Actually, viruses are considered nonliving things because they are unable to bear the characteristic of living things (such as respiration, reproduction, growth, excretion, and etcetera) on their own.  They only infect host cells to ride on the cell's biochemical machinery to be able to reproduce. Once outside the cells, they are non-living.

H2SO4 + NaOH → Na2SO4 + H2O
Ronch [10]

Answer:

Answer

4.0/5

4

Explanation:

The balanced chemical equation will be;

H2SO4 + 2NaOH → Na2SO4 + 2H2O

The equation for the reaction is balanced by using coefficients; 1,2,1,2

According to the law of conservation of mass the mass of the reactants should be equal to the mass of the products.

For the law of conservation of mass to be obeyed, chemical equations must always be balanced.

maksim [4K]

The answer is d.their cells have some differences in the sequence of nucleotides in their nucleic acids

Human and mice is both mammals and have similar structure and metabolism. There should be no big differences in biological or organic molecule. The big differences should be the sequence of the nucleic acids in their DNA. Mice could produce similar protein in human, but the DNA is different.

PtichkaEL [24]

Answer:

1. Muscle Fibers

2. Bones

3. Joints

Explanation:

Muscle tissue is made of muscle fibers. The plasma membrane of a muscle fiber is called sarcolemma while its cytoplasm is known as sarcoplasm. Muscle cells are characterized by the presence of specialized endoplasmic reticulum which is called sarcoplasmic reticulum.

Muscle cells exhibit contractility and extensibility. The ability of muscle cells to shorten their length forcibly in response to a stimulus is their contractility. Muscle fibers have the ability to extend and shorten themselves.

Extension and contraction of muscle fibers are responsible for the movement of the human body and its parts.

Muscles are attached to bones via tendons which in turn are the fibrous connective tissues. Muscles are also part of our joints where they assist in the movement by pulling the bones as well as stabilize and strengthen the joints.
