Answer:
True
Explanation:
Pioneer organisms are the first organisms that reoccupy a region that was destroyed by a disaster like flood, forest fire, volcanic eruptions, etc. These pioneer species can grow in the habitat that is barren and is not suitable for the growth and survival of other species.
Some of the pioneer species are lichens and algae. Pioneer species like lichens help in the formation of soil from breakdown or rocks which allow the formation of a suitable environment for the ecological succession of other species like mosses, algae, and other small plants. Therefore the statement is true.
Answer:
The correct answer is motion.
Explanation:
Lipids are the important constituents of plasma membrane. For example phospholipid,glycolipid,splingolipid,cholesterol builds most of the structural framework of the cell membrane.
Lipids plays an important role during cell signaling For example the phosphotidy inositol 4,5 bisphosphate one of important component of the inner leaflet of the the plasma membrane undergo hydrolysis to form Diacylglycerol(DAG) and inositol triphosphate(IP3).Both IP3 and DAG act as second messenger.
Lipid act as an insulator of myelein sheath that helps in the saltatory conduction of nerve impulse across the axon of unmyelinated nerve fibre.
Lipid does not involve in motion

Explanation:
The correct notation would be Del(6)(p24). The word 'del' means deletion.
<h3>What is chromosome notation?</h3>
Chromosome notation refers to alphanumeric notations used to identify certain chromosome arrangements.
In this case, chromosome notation denotes a deletion (del) in the short arm (p arm) of chromosome 6.
The stained band of the chromosomes in the karyotype is denoted by the number 24.

Answer:
Mutation is the source for new genetic variation: Genetic variation is brought about by random mutation. Without mutation, genetic variation cannot occur. Mutation is a change in the genetic code in DNA and can lead to a change in the protein that is coded for that segment of DNA.
Explanation:
Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.
