<span>Notice a couple of things
different between (A) and (B). It was NOT the first time a biologist
proposed that species changed through time (so it's not B). But it
finally *solidified* that idea by giving "change through time"
(evolution) a MECHANISM. It gave a plausible explanation for WHY
species change over time, in a testable way that made sense and had
evidence to support it.
So it finally dismissed the idea that species are constant.
It also emphasized that the simple presence of *variation* within a population was a key reason for evolution.
While we're at it ... (C) is wrong because it's not *individuals* that
acclimate (adapt) to their environment, but the population (the species)
as a whole.
And (D) is wrong because it had nothing to do with economics or the monarchy.</span>

<u>Answer:</u>
<em>Enzyme activity decrease at these temperatures.
</em>
<u>Explanation:</u>
Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH.
</em>
The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.
<em>At a temperature above 38°c and below 0°c enzyme activity decreases.
</em>

1) Approximately 0.02-0.2 in diameter.
2) They are eukaryotic.
3) They contain protien capsid and lipoprotien envelope.
4) Donot replicate by binary fission.

1) Not typically associated with human disease.
2) Found in extreme environments.
3) Cell wall doesn't contain peptidoglycan.
Answer:
The correct answer is - tissues.
Explanation:
The tissue is an organization of the cells to work together to perform a specific type of function in an individual organ or body system of an organism. The skin cells of the scorpion also organize together to play the role of hard covering that helps the scorpion to be protecting.
This organization of cells is known as carapace which is a tissue made up of cells together to protect scorpion as tissue is a group of similar cells working together.
