Answer 1
Answer:

Answer:

1. True.

2. False.

3. False.

4. True.

5. True.

Explanation:

1. True: The intestines breed both helpful and harmful microorganisms. This relationship between the host and these microorganisms is called a symbiotic relationship.

2. False: A child is born with many microbes in his or her body. Basically, it has been established that there are no microbes in the womb of pregnant women (mothers) and as such babies are not exposed to any microbe until when they are born.

3. False: A child is usually born with all of microorganisms that live in the human mouth. This is false as well because the womb and placenta is essentially free of bacterias, fungi and other microbes.

4. True: The intestines are a good breeding place for microbes. This is completely true because of the regulated temperature and it mainly contains foods which the microorganisms live on.

5. True: Animals provide a means to test and understand various disease germs. Animals such as squirrels, rats, mice, frogs, monkeys are all used as specimens for testing and understanding various diseases and germs.

What are the frist 3 stages of the cell cycle called?

Answers

The first three stages of the cell cycle are collectively called the "Interphase". Interphase comprises 3 stages specifically G1, S1 and G2. G1 is called the First Gap Phase, followed by S phase for synthesis and then G2 for the second gap phase. I hope this helps you. 
Interphase proceeds in three stages, G1, S, and G2, preceded by the previous cycle of mitosis and cytokinesis. The cell's nuclear chromosomes are duplicated during S phase.

Plant tissue culture is a method of asexual reproduction used to produce clones of a plant with desirable traits. Plant tissue culture relies on the fact that plant cells have the ability to regenerate a whole plant. Single cells are dosed with certain chemicals that trigger dividing cells to produce roots, shoots, and leaves. Which tenet of cell theory BEST serves as a basis for this type of biotechnology?

Answers

The answer is Cells come only from pre-existing cells.

There are three tenets of cell theory:
1. All living organisms are composed of one or more cells.
2. Cells are the basic structural and functional units in all living organisms.
3. Cells come only from pre-existing cells.

In plants tissue cultures, single cells divide to produce roots, shoots, and leaves. This division suggests there must be some pre-existing cells from which those organs will be produced. So, the tenet that cells come from other cells in cell division is a basis for plant tissue cultures.

a. True
b. False

Answers

Nuts indeed are a good source of vitamin E. This is true. However, when talking about nuts we have to consider that not all nuts have the same nutritional information nor do all of them have plenty of vitamin E. While we can say this for most, it is necessary to be wary of making such statements. 
true is the correct answer.

Which process uses energy to combine inorganicmolecules to synthesize organic molecules?
(1) respiration (3) photosynthesis
(2) digestion (4) decomposition

Answers

The process which uses energy to combine inorganic molecules to synthesize organic molecules is referred to as(3) photosynthesis.
The chemical energy which is basically formed in carbohydrate molecules for each sugar and are being synthesized by water and carbon dioxide. Photosynthesis is also performed by most cyanobacteria and algae.
Some of this organisms are called photoautotroph. Photosynthesis is well known for maintaining and producing oxygen content of the earth's atmosphere. The process of photosynthesis begins when energy which is from light is being absorbed by proteins known as reaction centers and contain green chlorophyll pigments.
When in plants the proteins are being held inside the organelles known as chloroplasts and abundant in life cell.
