They are called natural recyclers because they naturally break down dead and decaying matter. I hope this helps!---
Answer:
A
Explanation:
<em>The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.</em>
Total number of cell in division = 20+4+2+4
= 30
Probability that a randomly chose cell will be undergoing cell division = <em>number of cells in division/total number of cells</em>
= 30/200
= 0.15 or 15%
The correct option is, therefore, A.
The correct options are, frying an egg and burning candle.
Explanation :
Physical change : It is a change in which no new compounds are formed only changes occurs in size or state of substance. In this, there is no changes in the substance or compound.
Chemical change : It is a change in which a new compounds are formed by the chemical reaction. Changes occurs in their chemical composition and properties.
Frying an egg : It is a chemical change because a new substance is form by heating.
Burning a candle : It is chemical change because new substances are formed (carbon dioxide, water and heat) by burning.
Boiling alcohol : It is physical change because only changes in the state.
Melting and ice : It is a physical change because only changes in the state.
Making coffee : It is a physical change because no new substance is formed.
Therefore, frying an egg and burning candle are the example of chemical change.
Answer:
Nucleic Acids
Explanation:
Between carbohydrates, lipids, proteins, and nucleic acids, DNA and RNA molecules most accurately fall under the macromolecular category of nucleic acids.
Answer:
Hypertonic is normalize by hypotonic solution.
Explanation:
We will treat cells that are either hypertonic or hypotonic by giving solution that is opposite to that solution. If the patient is dehydrated so their blood is considered as hypertonic solution. They will need an opposite solution i. e. hypotonic solution in order to bring their tonicity back to the normal range while on the other hand, if the body is hypotonic so the hypertonic solution is needed to maintain homeostasis in the body.
