Answer:

c. A chromosomal mutation can change the total number of chromosomes in the cell.

Explanation:

A gene mutation affects a single gene, and replication error is the main cause of gene mutation. A chromosomal mutation affects one part of chromosome or full chromosome. error in meiosis is the main cause of chromosomal mutation. Both mutations are responsible for a change in DNA. A chromosomal mutation leads to the change in total number of chromosomes in the cell.

Can you list the types of organisms in order in which they would appear during primary succession?

nignag [31]

Answer:

Primary succession is one type of the ecological succession which takes place on the land devoid of vegetation or barren land.

The species which first flourishes on this barren land are known as pioneer species which includes the species of bryophytes and pteridophytes like lichens and mosses.

These lichens and mosses help breakdown the barren rocks through chemical leaching and help increase the nutrient content. This allows the ferns and small pteridophytes to grow.

Then the area is colonized by the intermediate species which includes herbs, shrubs later trees. These intermediate species help attract the animals and thus help establish the biological community.

Thus, Lichens mosses → herbs→ shrubs →trees.

How secretion and excretion both are different? Explain in simple language.

gtnhenbr [62]

Answer:

Excretion is the removal of material from one living thing, for example. Humans excrete tears, sweat, carbon dioxide etc.

Secretion is the movement of material from one point to another, for example. Humans secrete enzymes, hormones, saliva etc.

Basically in summary excretion is the removal of physical material and secretion is the movement of biological materials from one point to another.

I hope this was clear enough lol
