Which of the following is a radical?<br> O <br> H20<br> OH<br> H
svetoff [14.1K]

Answer:

<em>The correct option is C) OH</em>

Explanation:

In the field of chemistry, radicals can be described as atoms, molecules or ions which have at least one unpaired electron.

The formation of a radical occurs when a single covalent bond breaks so that each of the atoms that had been involved in the formation of the covalent bond can have an unpaired electron. Examples of radicals include OH, NH4+ etc.

Other option, like option B, is not true because a molecule of water does not have any unpaired electrons in its valence shell.

Lipid-soluble hormones readily diffuse through capillary walls, whereas water-soluble hormones, such as proteins, remain in the
solong [7]

Answer:

b. pass through pores in the capillary endothelium

Explanation:

The fenestrated capillaries and sinusoids have pores in their endothelium. These pores or the intracellular clefts vary in size between the fenestrated capillaries and sinusoids. Sinusoids have larger intracellular clefts. The pores serve as a passage for the movement of water-soluble substances, proteins and other substances that cannot cross the hydrophobic interior of the cell membranes.

Water-soluble hormones also cannot pass through the capillary walls. Therefore, these hormones pass through the pore or the fenestrations present in the endothelium of capillaries.

Explain how the wind may be involved in the formation of sandstone arches.
WITCHER [35]

Answer

Wind may be involved in the formation of sandstone arches by facilitating erosion which wore away exposed sections of rocks and enlarges the cracks on the surface forming marrow sandstone fins.

Explanation

Sandstone arches can be formed when a large piece of sandstone flaked off as a result of high winds. In addition to that, alternative frost and thawing can result into crumbling of porous sandstone which will in the long run cut through some fins. These resulting holes enlarge to form arches with effects of weathering and rock fall caused by wind.

In Drosophila, straight wings are dominant to curved wings (c), smooth eyes are dominant to sparkling eyes (spa), and tan body i
77julia77 [94]

Answer:

\frac{1}{8}

Explanation:

Straight wings are dominant over curved wings

Let Straight wings : H

curved wings : t

smooth eyes are dominant to sparkling eyes

let smooth eyes = H

spark ling eyes = t

tan body is dominant to ebony body color.

Again; Let tan body color be H

Let ebony color be t

If flies that are heterozygous for all three traits are crossed;

we have HtHtHt × HtHtHt

Then the selected trihybrid traits for the cross will be (HHH,HHt, HtH, Htt, tHH, tHt, ttH, ttt)

We will realize that from the punnet square in the diagram below, the proportion of the offspring would you expect to be heterozygous for all three traits (i.e HtHtHt) is asterisk in the punnet square and will be \frac{8}{64}

= \frac{1}{8}
