<span>The answer would be: No, the baby is most likely in the REM sleep stage
</span>
One of the cycles of sleep called Rapid Eye Movement or REM. In this cycle, the eye is moving constantly and intermittently. The eye movement is not voluntary and the baby is not a sign of waking up. This cycle is important, so the parent should not interrupt it by waking the baby.

(WILL GIVE BRAINLIST) A student investigated the effect of root space on plant growth. The student grew two groups of plants of
My name is Ann [436]

Answer:

Throughout the experiment at hand, the student will likely find that root space does indeed effect the length to which plantswill grow. Although I could not locate the table online, I will offer a general hypothesis for what the experiment will conclude. The student is testing the effects of root space on the way plants grow. The students experiment is well designed, keeping many variables constant and making sure that the amount of root spaceis the only difference between the plantsensures the accuracy of the experiment. Since we know that the experiment is well designed we are able to directly infer the effects of root space limitations without having to account for other factors. We can assume that the limited root space will in turn limit the extent to which a plant can grow. This is because plants need larger and deeper roots to support extended growth. Therefore, the plants in group Bwill grow smaller than those in group A.

Annette [7]

Answer:

B) Changes in the temperature and salinity of water.

Explanation:

<em>Options</em>:

A) Migration of bottom feeders into the region.

<u>B) Changes in the temperature and salinity of water. </u>

C) Migration of fresh water fish to places near the mouths of rivers.

D) Formation of breeding grounds for various species in the shallow waters.

Sea level changes are among the most relevant issues that our planet is facing due to climate change. This phenomenon impacts the salinity and temperature of the ocean because of the melting of glaciers, and ice sheets. Therefore, <u>melting ice alters the level of salinity of the water which, along with temperature, also effect the density of the ocean water, altering ocean currents and productivity.</u> These impacts alter the distribution, behavior, and ecology of marine organisms.

<em>*Note: The melting of the glaciers and ice sheets - result of anthropogenic climate change - has increased sea level.</em>
