NeX [460]
The conversation between madame valmonde and desiree gives an example of Foreshadowing; situational irony;
Considering this Quote;
Madame Valmonde "shuddered at the first sight of it.....It was a sad lokking place.......The roof came down steep and black like a cowl, reaching out beyond the wide galleries that encircled the yellow stuccoed house. Big, solemn oaks grew close to it, and their thick-leaved, far-reaching branches shadowed it like a pall."

The imagery in this quote reveals the darkness of a place that is ironically called a shelter, and Madame Valmonde mentions the "pall" that is cast over the house , that being a term related to death.

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.

liberstina [14]

The hypothesis that the scientist could test in his investigation is as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.

<h3>What is an hypothesis?</h3>

Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation.

An hypothesis is commonly referred to as an educated guess because it tends to provide a temporary explanation for a phenomenon.

According to this question, a scientist investigated whether giving plants different quantities of magnesium affected their growth. He measured growth by counting the number of new leaves produced.

The hypothesis of the scientist regarding the above experiment could be as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.
