The climate of a certain area is cold, and snow is
pantera1 [17]

Answer:

Explanation:

Based on the information provided within the question it can be predicted that the population of the brown rabbits will diminish over time or may even go extinct, while the white rabbit population will thrive. This is because the white rabbits fur color allows it to better blend into it's environment and hide from predators, which in term leads to their survival as opposed to the brown rabbits which have nowhere to hide in the snow.

A total of _____ amino acids compose the majority of protein in living things and nine are _____ to human
Evgen [1.6K]

A total of <u>20</u> amino acids compose the majority of protein in living things and nine are <u>essential</u> to human.

  • All living organisms, from bacteria to people, depend on amino acids for survival.
  • The same 20 types of amino acids are present in all living things.
  • Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
  • Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
  • The body is unable to produce essential amino acids. They must therefore originate from food.
  • Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.

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.)
