The correct answer is:

D. volcanic eruptions

Explanation:

4.0 Billion Years Ago, Earth’s outside cools enough for most of the water that has accumulated in the atmosphere from comets and volcanic outgassing to rain down to the surface and fill in the basins making the world’s oceans. Explosive volcanic eruptions change the global climate largely through including sulfur, improve the salinity near the Greenland Sea, and considerably reduces static balance, which means more surface water sinks into the deep ocean.

The modern synthesis brought together Darwin's theory of evolution with Mendelian genetics. Why was this so important?
MakcuM [25]

Answer:

Option C

Explanation:

Options for the question are

a.  It demonstrated that nothing in biology makes sense except in the light of evolution.

b.  It demonstrated that species arise from other species.

c.  It provided a quantifiable mechanism to explain gradual evolutionary change.

d.  It was the first time that change in biological organisms was observed.

e.  It was not very important to evolutionary biology.

Solution -

The term modern synthesis by coined by Julian Huxley and the goal of this synthesis was to understand and determine how genetics bring evolutionary changes in a population and with this objective it combined the Darwin’s theory of evolution and Mendel’s work on heredity. Later on scientist Dobzhansky under this synthesis found that genetic mutation causes variation through the process of natural selection and hence lead to evolutionary changes in a population even if they are isolated for a long time.  

Hence, option C is correct

Processes that increase the density of seawater include evaporation and
Natali5045456 [20]
<span>Processes that increase the density of seawater include evaporation and sea ice formation. The density of seawater primarily depends on two factors, temperature and its salinity. When temperature is decreased and salinity is increased, the density increases. Sea ice formation lowers the seawater's temperature, while evaporation increases the salinity.</span>

Which agent would cause the least damage to a chromosome?
Alex777 [14]
Hey there!

The answer would be ultrasound.


The ultrasound is considered safe because it uses sound waves for the detection of tissue, organ, baby etc. These waves are considered safe and transfer only a small amount of heat to the tissue in which the ultrasound is done. A little amount of heat is not at all harmful to the body in any means. Early defects of baby can be detected through this procedure, the merits of the process is much higher than its demerits.
