3. What things does your body do automatically to cool down or warm up?

Answers

Answer:

For your body to cool down one method is to sweat.

Explanation: Your sweat glands release sweat, which cools your skin as it evaporates. This helps lower your internal temperature

To keep warm your body shivers and your blood pressure decrease, it brings the blood back to the heart to keep you warm, also in you blood, your hormones create glucungons that makes the liver shoot out glucose to keep you warm. To keep cool you body sweats and in you blood the hormones create something called insulin that makes you cell take in the glucose in you blood.(Fun Fact: the things that I just said are negative feedback).

What two factors play a role in the type of snow flake created?

Explanation:

Carbohydrates like glucose can undergo spontaneous rearrangement to give an alternate configuration for the anomeric carbon when the ring is free in solution. However, when glucose is covalently attached to another sugar through C1, this rearrangement cannot occur. Consequently, the configuration of carbohydrate oligomers and polymers is fixed. Why can't glucose rearrange when in a polymer form?

Answers

Answer:

The presentation according to another circumstance is categorized in the following section.

Explanation:

Glucose constructs anomers because of the extreme involvement of flexible metal-carbon because that continues to exist as something of a monomer. However, when plastics are established, transformation is limited with glycoside formation of complexes among both anomeric carbon atoms.

Sucrose, besides obvious reasons, would be manufactured by glucose and fructose, which have been connected by something like a glycerol backbone involving glucose carbon atom as well as fructose. The mechanism including its creation of anomers even by movement through carbon becomes called "Mutarotation" Sucrose doesn't always show mutation.

Answers

The graph is attacged and the options is as follows:

Temperature of 27oC and a pH of 4

Temperature of 37oC and a pH of 6

Temperature of 40oC and a pH of 8

Temperature of 50oC and a pH of 10

Answer:

The correct answer would be - temperature of 37oC and a pH of 6

Explanation:

The graph 1 shows the relation between the rate of reaction for an enzyme and the temperature of  reaction is been represented. In this graph the rate of eaction is highest (point from the slope starts decreasing) at the So, by the options and graph the temperature 37°C(Below 40°C) rate of reaction is maximum.

Similarly, in other graph rate of reaction and and pH has been represented in which rate of reaction is maximum at pH 6. after 6 pH the rate of reaction started decreasing.

There is a multitude of evidence that supports how life has changed over time due to variation in the gene pool of different species. Which of the following choices below represents a scientific theory that explains these changes? *
A. As environments and ecosystems change over time, those that acquire suitable traits are more likely to survive and reproduce and the gene pool changes because organisms must adapt to survive and reproduce.
B. As environments and ecosystems change over time, those with variations for traits that are more successful in the new conditions are more likely to survive and reproduce, thus changing the allele frequency in the gene pool.
C. Because the environments and ecosystems show little change over time, organisms are already adapted for surviving in their given habitats for which they are made.
D. Because the environments and ecosystem show little change of time, the organisms that choose to adapt to different environments will migrate and become suited for new habitats.

Answers

Answer: A. Environmental drivers plus genetic variation in the population result in natural selection

Explanation: over geological time environmental conditions change. Organisms do not survive in one environmental niche with traits adapted to a possible future change that might suit those traits. Adaptation is not a matter of choice: adapt if possible or go extinct.

There is a (badly named) concept called pre-adaptation, which is that variations in some existing trait render adaptation to a different environment more likely.
