Answer:
Give at least 3 reasons why viruses are considered non-living and therefore NOT classified into the Linnaean system of life.
Viruses as we know that they are micro-organism but they are not produced from cell
Viruses does not grow rather undergo replication by multiplying into several number within minutes
also they rely on host energy as they could not produce energy needed for their usage.
Explanation:
Every living organism are made up of cells which makes it the fundamental unit of life where virus does not fall into such category, Growth is an essential characteristics of every living organisms, viruses only replicate rather they does not undergo growth.
The question is incomplete as it does not have the options which are:
aneuploids
allopolyploids
amphipolyploids
autopolyploids
Answer:
Autopolyploids
Explanation:
Autopolyploid refers to the ploidy condition in organisms in which the ploidy level of organism increases that is multiple set of a single chromosome is formed in tissues.
The autopolyploids condition is observed more frequently in the plants than the animals when the tissue cells divide. In the given question, the chromosome number increases or double that is from 18 to 36 to 54, 72 and 90. This shows that the ploidy level is increasing.
Thus, Autopolyploids is correct.
Answer:
In this given statement , the plastic base becomes negatively charged because plastic is an insulator . And the metal cup does not become charged because metal is a conductor.
Explanation:
<u>Reason behind , why plastic base becomes negatively charged -:</u> When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.
<u>Reason behind , why the metal cup does not become charged -:</u> The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .
