Answer:
The correct answer will be option-B.
Explanation:
<em>Homo neanderthelensis</em> or Neanderthals are the close relatives of the <em>Homo sapiens</em> or modern humans which became extinct around 10,000 years ago.
The Neanderthals and sapiens are the two related species of the same genus Homo but they showed distinct features like Neanderthals were muscular and shorter in height compared to the <em>Homo sapiens</em>. Recent fossils indicated that Neanderthals and<em> Homo sapiens</em> interbreed in some parts of the world as they were closely related to each other.
Thus, Option-B is the correct answer.
Base pairing between the DNA template strand and the RNA nucleotides
Answer:
True
Explanation:
The Devonian Period comprises the years between 416 million and 354 million and is subdivided by periods: Lower (the oldest), Middle and Upper (the most recent).
During this period, the main transformations occurred in the flora, with the exponential growth of small terrestrial plants through the development of spores. With this process, plants will become more similar with modern plants. During this period the plants were able to fertilize themselves with the seeds and reach the height of trees. They formed the first forests to be recorded, with the appearance of licopodia, ferns and progimosperms.

Explanation:
Answer:
Glands made up of parenchyma of glandular epithelium that forms the secretory portions of the glands.
Glandular epithelium is a modified form of columnar epithelium. Their cells are modified to secrete certain substances. It lines the stomach, intestine and other secretory organs.
The glands occur singularly as unicellular glands. Unicellular glands are the goblet cells in the mucous membrane of the alimentary canal.
It may occur congregate to form multicellular glands which includes sweat glands and sebaceous glands in the skin, mammary glands and salivary glands, etc.
Glandular epithelium secretes sweat, milk, digestive enzymes, oil and other hormones.
There are two types of glands: exocrine and endocrine glands. Exocrine glands can be unicellular or multicellular. They have ducts and secretion is delivered into these ducts and end up on the epithelial surface. For example: sweat glands.
Endocrine glands are without ducts and secretions are released directly to the bloodstream. Example: pineal gland, pituitary gland.
Note:
Glandular epithelium are the specialised epithelial cells that secrete glands. They are of two types: endocrine and exocrine glands. Exocrine glands hold secretion for covering and lining of the body until secretion is needed. Endocrine glands control hormone production and enclose the formed hormones until they are needed in the body.
