Answer:
1) Nitrogenous bases
2) Nucleotides
3) Purines
4) Pyrimidines
Explanation:
1) Each one is made up of a pentose , a group, and one of four Nitrogenous bases
2) Adenine, guanine, cytosine and thymine are Nucleotides
3. Adenine and guanine, which have a nine-member double-ring, are called Purines
4. Cytosine and thymine, which have a six-member single-ring, are called Pyrimidines
Answer:The difference between seed plants and seedless plants is that seedless plants do not bear seeds for propagation, whereas seed plants bear seeds for multiplication. ... Seed plants mainly multiply by seeds. Seedless plants multiply by spores that may produced asexually or as a consequence of asexual reproduction.
Explanation:
Answer:
The question is incomplete as the boxes of description is not given but the missing part is attached in the image-
Brain and spinal cord have a membranous covering made up of three layers, altogether known as meninges. These 3 layers are known as the Dura mater follows by the arachnoid mater and inner layer is the pia mater.
The description of the different layers are as follows-
1. Dura mater is the most superficial layer of the meninges. The superior sagittal sinus is present within this dura mater.
It creates tough inward folds that distinguished the cerebral hemispheres. Lines the inner side of the cranium in the skull.
2. Arachnoid mater is the middle layer present under the dura mater layer that surrounds the subarachnoid space. This layer is present Immediately deep to the subdural space.
3. Pia mater makes the deepest layer that follows the contours of the surface of the brain.

Meiosis takes place in reproductive cells, whereas mitosis happens in somatic cells.
<h3>What is Mitosis ?</h3>
A single cell divides into two identical daughter cells during the process of mitosis.
<h3>What is Meiosis ?</h3>
A single cell splits twice during the meiosis , resulting in four cells with half the original genetic material.
<h3>What makes mitosis and meiosis distinct from one another?</h3>
- In contrast to mitosis, which results in 2 daughter cells at the end of cell division, meiosis results in 4 daughter cells.
- Meiosis results in the creation of four daughters with half of their parents' DNA as opposed to mitosis' two genetically identical daughter cells.
- Meiosis produces haploid cells, while mitosis creates diploid cells.
