Answer:

explanation below

Explanation:

The control group would be the biodiversity of the trees without the fire

The control group in the experiment would center on the biodiversity of the trees without the fire. Ideally, both the control group and the experimental groups are usually identical in every way except that the experimental group would receive the treatment that is believed to have an effect on the biodiversity of trees.

Which of the following best describes the structure of a mushroom that you observe above the ground
Norma-Jean [14]

The right answer is Fruiting type

The sporophore (literally "spore carrier"), also called Fruitbodies, is the reproductive system of the so-called superior mushrooms. It is, in popular language, the organ of the "fructification" of the mushroom mycelium. It contains sporocysts (basid and asci) that differentiate in the hymenium and produce spores in various forms. It is present in the mushroom's cap.

Which two factors of a molecule determine whether or not it can cross the membrane? A. Color and weight B. Shape and texture C.
myrzilka [38]
D. Polarity and size. 
<span>The size, polarity, and charge of a substance will determine whether or not the substance can cross the cell membrane by diffusion. The cholesterol was an example of a lipid, and is highly soluble in the nonpolar environment of the lipid bilayer. You saw, in the animation above, the cholesterol freely passing into the hydrophobic environment of the membrane. Cholesterol distributes freely in the membrane and then some fraction will dissolve in the aqueous environment of the cytoplasm. Water, on the other hand, while polar, is small enough to cross the membrane at a slow rate. Note that specialized transport proteins in certain cell membranes can provide a channel for the water, greatly increasing its rate of crossing the membrane. The lipid bilayer is much less permeable to the ion, because of its charge and larger size. As a general rule, charged molecules are much less permeable to the lipid bilayer.</span>
