Answer:
A.The DNA in the parent cell nucleus makes a copy of itself and is then split between the two daughter cells during meiosis.
Explanation:
Ionic bonding?
the bonding between non-metals and metals
non-metals form negative ions, so they are attracted to metals, which form postive ions
Catenation:
The property of self linkage among identical atoms to form long chain compounds is known as catenation. Carbon exhibits maximum catenation, when compared to elements like sulphur and silicon, due to strong carbon-carbon bonds and tetra valency. Due to this catenation, carbon atoms can form various types of straight chains, branched chains and ring structures.
Formation of multiple bonds:
Carbon atoms are capable of forming multiple bonds with other carbon atoms.
Hydrocarbons:
All the carbon compounds which contain just carbon and hydrogen are called hydrocarbons.
isomerism arises from the difference in the structure of carbon chain which forms the nucleus of the molecule. It is, therefore, named as chain, nuclear isomerism or Skeletal isomerism. For example, there are known three pentanes which have the same molecular formula.
The "soil type" is an example of abiotic factor to an earthworm. Abiotic factors are the non-living factors which influence the earthworm present in soil. Thus, the correct option is A.
<h3>What is Abiotic factor?</h3>
Abiotic factors are the non-living components of the environment that affect living organisms and the functioning of the ecosystems as a whole.
Soil type is an abiotic factor for the earthworm present in it. The soil helps an earthworm to collect food and hence in increasing its population. Soil is made up of the rocks, minerals and other non-living particles.
Therefore, the correct option is A.
