Inga [223]

Answer:

The correct answer will be-<em> </em><em>Homo neanderthalensis</em>

Explanation:

The closest ancestor of modern humans which evolved in the Pleistocene age which was around 7 lakh to 3 lakh years is the <em>Homo neanderthalensis</em> or Neanderthals.

The Neanderthals became extinct around 12,000-10,000 years ago by competitive <em>Homo sapiens</em>.

The specimens of Neanderthals are collected from the central and Western Asia and parts of Europe and showed approximately the same cranial capacity which is around 1450-1500 cc.

Thus, <em>Homo neanderthalensis</em> is the correct answer.

What tissue makes up most of the wood of a tree? A. primary xylem B. secondary xylem C. secondary phloem D. vascular cambium
Over [174]

<u>B. Secondary xylem</u> tissue makes up most of the wood of a tree.

<h3><u>What exactly is secondary xylem?</u></h3>

Secondary xylem is a sort of xylem produced by secondary growth. During initial growth, in contrast, the primary xylem develops. As a result, the secondary xylem is linked to the primary xylem by lateral growth as opposed to the vertical extension.

The kind of cambium that gives rise to each difference is another point of differentiation. The vascular cambium produces the secondary xylem, while the procambium produces the primary xylem.

Unlike trees and shrubs, non-woody plants lack secondary xylem. It gives such plants mechanical support by depositing lignin into their cell walls, thickening them. Compared to the major xylem, the secondary xylem is made up of tracheids and veins that are shorter and wider. In comparison to the primary xylem, it is also richer in xylem fibers.

Possible growth rings in the secondary xylem (or annual rings). Sapwood and heartwood are two differentiators of the secondary xylem in big woody plants.
