Because global temperatures are ________[1], some species are seeking out ______[2] elevations in the Himalayas to colonize. Sci
Vsevolod [243]

Answer:

increasing[1], higher[2], space[3], food[4], climate change[5].

Explanation:

Because global temperatures are <u>increasing[1]</u>, some species are seeking out <u>higher[2]</u> elevations in the Himalayas to colonize.  Scientists were worried that these organisms would not have enough <u>space[3]</u> to live, but they have found that there is adequate <u>food[4]</u> at higher elevations. This movement may help these organisms survive the effects of <u>climate change[5].</u>

(Although am positive about 1, 2 and 5, you will need to double check 3 and 4.  What I can tell you is that I don't think lifespan has to do with 3 or 4.  I chose space and food simply due to the thought that more species moving to higher elevations allows for less space to live, but more prey to be hunted easier.)

A student made a model of a cell. First, she filled a clear plastic bag with gelatin.
Ksivusya [100]
B) the model does not show that cells can contain smaller structures inside.

This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.

Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.

Aleonysh [2.5K]
In order to understand the totality of the interactions among the organisms in the biosphere, we need to at least understand <span>how the all genes function within organisms and </span>interact<span> with others organism and environment around it.
If we try to make this effort in a world where organisms will keep evolving and environment will keep changing like us, that tasks is impossible to finish.</span>

In a species of snail, dark-shelled individuals are better hidden from bird predators in the shady forest, while light-shelled i
Harrizon [31]

Answer:

C. Disruptive Selection

Explanation:

Disruptive selection occurs when two extremes of continuous variation are favored more than intermediate traits.  

The extremes of continuous variation exhibited in this species of snail is the color of their shell which allows them to blend with the background of their habitat.  

The shady forest of the habitat makes the dark-shelled individuals to be better hidden from bird predators, while the light-shelled individuals are better hidden in well-lit brushy edge areas. This disruptive coloration exhibited by both individuals makes both individuals of this species of snail less vulnerable to predation.  

Both individuals of this species both extremities would naturally survive in this habitat as snails with intermediate extremities would be highly preyed on since there is no area of intermediate brightness in the habitat to make them invisible to predators
