Answer: A) increased adherence of phagocytes to microorganisms

Explanation:

The phenomenon of phagocytosis can be facilitated by certain substances called opsonins. Particles coated by antibodies or by certain products of the activation complement system adhere to the phagocyte membrane and are internalized more rapidly and intensely than those that are not opsonized. In the macrophage membrane, there are surface molecules, known as receptors, that have an affinity for these opsonins.

Compare and contrast the structures of DNA and RNA
katovenus [111]

The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.

Explanation:

Water can hydrogen bond to other molecules due to the O-H bond present in water with partial charges. Water can form hydrogen bonding with other polar molecules. The answer would hence be Solutions are formed when the water's polar molecules separate the polar molecules of an ionic or molecular compound(because polar water dissolves polar molecules in between their interactions).

Reasons for seasons<br>​
Sergio039 [100]

Answer:

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer. Without the tilt of the earth's axis, we wouldn't have seasons.

Explanation:

Hope this helps!
