Biology Interview Questions and Answers will guide all of us now that Biology is the science that studies living organisms. Prior to the nineteenth century. Biology came under the general study of all natural objects called natural history. Learn the basic and advance Biology concepts here with this Biology Interview Questions and Answers.

198 Biology Questions and Answers:

1 :: Which is better to grow plants in Rock sand or soil?

When we grew plants inside, with no wind, and the plants in the rocks grew better than the plants that were growing from the sand and dirt from outside.

2 :: What happens when the cell membrane or plasma membrane ruptures or breaks down?

When cell membrane ruptures Ions leek out and unless repaired in time the cell will die. As we know that the plasma membrane is not stationary, and it is made of lipids and protein, so when damage happens the cell repairs itself by producing new part like the damaged one that is why it is dynamic.

3 :: What are analogies for mitochondria?

Well, as you know, the mitochondria are the producers of most of a cell's energy and the nucleolus creates ribosomes. The cell wall is only in a plant cell and is a rigid layer of non-living material that surrounds the cells of plants and some organisms.

4 :: What is a terrestrial organism?

'Terra' is the Latin word for earth. Therefore, an animal that lives on the surface of the earth is called terrestrial. This is the same root word as 'extraterrestrial' meaning an alien.

5 :: What is the optimum temperature for catalyses?

For any chemical reaction, the reaction rate increases with temperature, so the higher the temperature, the faster the rate. For any enzymatic reaction, the reaction rate will increase with temperature until the temperature at which the enzyme begins to denature is reached, and this is the optimum temperature.

The denaturizing temperature depends on the composition of the protein (its amino acid sequence), which varies for catalyses from different organisms. Therefore, the answer to your question is that the optimum temperature is dependent on the source organism.

7 :: What is the difference between an acid and a base?

Base is any thing, which has a capability to abstract a proton.

Using the simplest definition, an acid is something when added to water releases hydrogen ions (H+), also called protons. A base, or an alkali, is something that when added to water releases hydroxide (OH-) ions.

The strength of a basic (or alkaline) or acidic solution is measured using the pH scale. A pH of 7 is perfectly pure neutral water (neither acidic nor basic), and pH below 7 is acidic, and a pH above 7 is basic.

There is another definition, which says that an acid releases H+ and a bases remove H+ from water. This definition is a bit more general than the first one above. Note that releasing OH- is the same as removing H+. This is because when OH- mixes with H+, they form neutral H2O, and so for every OH- released, one H+ is removed by combining them into water.

The final definition of an acid and base is the most general, but the hardest to understand conceptually, and it is not always taught in high school because of this. According to this definition, acids are electron pair acceptors, and bases are electron pair donors.

8 :: What is cell biology?

Cell biology is the science of studying how cells function such as their reproduction and metabolism, their internal and external anatomy.

9 :: What is a recessive gene?

With the birth of a child, it gets its genes from both parents. Some genes 'override' other genes. Using hair color as example:

If one parent is blond (Pb) and one parent is black hair (Pd), blond would be the recessive gene, and dark would be the dominant gene. Meaning:

Pb x Pb = Blond Pd x Pd = Dark Pb x Pd = Dark Pd x Pb = Dark

Recessive genes occur in the genotype (inside the body, disease, disorder) or fenotype (appearance, blue eyes brown eyes). In all other cases, the dominant gene will override the recessive gene.

10 :: Does seed germination affect plant growth?

Germination does affect plant growth

Without germination in the plant, the plant is not able to grow. The germination is the beginning of life for the seed plant

However, the rate of germination is not directly related to rates of plant growth one can find speedy germinating seeds, which grow slowly and vice versa.
