The information given about enzymes suggests that the enzymes have the capability to change their size at higher temperatures which affect their activity.
<h3>What are Enzymes?</h3>
Enzymes may be defined as biocatalysts that perform the important function of increasing the rate of a chemical reaction without being consumed in the process. It may be thought that all cellular reactions and processes are mediated by enzymes.
Temperature is a physical property that can significantly affect the activity of enzymes. It results in the denaturation of enzymes, irreversibly altering their structure. Enzymes perform their most suitable activity at the temperature of 37°C.
Therefore, the information given about enzymes suggests that the enzymes have the capability to change their size at higher temperatures which affect their activity.

Answer: 1. S = 0.77
2. R = 0.14
Explanation:
1. <u><em>Selection</em></u> <u><em>differential</em></u> is the difference between the population mean and the average of the selected parents. Its symbol is S.
S = mean of selected parents - population mean
S = 6.48 - 5.71
S = 0.77
2. <em><u>Response</u></em> <em><u>to</u></em> <em><u>Selection</u></em> is how much gain you make when crossing over selected parents. Its symbol is R.
R = mean of offspring of selected parents - population mean
R = 5.85 - 5.71
R = 0.14
3. <em><u>Heritability</u></em> is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².
To calculate it, use Breeder's Equation:
R = h²S
h² = 0.18
4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.
The light-dark cycle caused by the rising and setting of the sun is responsible for what are called circadian rhythms. These are biological processes that show a cycle of around 24 hours, the time between consecutive rising of the sun. Experiments have shown that without the external cue of sunlight, the circadian rhythms of organisms tend to break down. These can be reset by being re-exposed to these cues. Jet lag is due in part to a re-setting of the circadian rhythm, as you travel to a different time zone, your body has to become used to a different timing of night and day. <span> </span>
Answer:
Archaebacteria are primitive, single-celled microorganisms that are prokaryotes with no cell nucleus. Each archaea has the ability to live in very severe environments.
Archaebacteria are one of the six kingdoms of life: plants, animals, protists, fungi, eubacteria and
