Answer:

Answer is A. True.

Explanation:

Organisms have developed an adaptive property which will enable them to adapt to cold temperature, through increase in their membranes fatty acid. This process allows them to keep the liquid-crystalline sate of their cell membranes at a cold temperature. This process is known as the homeoviscous adaptation.

This process is done by organisms especially the mammals to maintain functional membrane phenotypes.

A. Cellular Respiration – what type of reaction? ….and how much energy?
Elina [12.6K]

Answer

:a. Cellular Respiration – what type of reaction?  EXERGONIC .and how much energy  34 ATPs;Net gain of 32.

b. Why doesn’t sugar just explode on our countertops- sugar is a high energy-rich compound. Therefore high energy is needed to breakdown the bond-energy  in it for phosphorylation to take place in glycolysis  

c.<u> Photosynthesis – what type of reaction-</u>ENDOGONIC  ….how much energy 18 ATPs used up and 12NADPHs  

d.Where does the activation energy come from for photosynthesis SUNLIGHT

e. <u>Day to day, we use</u> ATPS <u> it is our energy coinage, we c</u>an STORE it and then cash it in.  

f. What is the delta G value for breaking ATP down into ADP=−30.5 kJ/mol

Which best describes the offspring of protists?
Hunter-Best [27]

Options found elsewhere:

-always genetically identical to one parent

-always genetically identical to both parents

-never genetically identical to one parent

-sometimes genetically different than both parents

Answer:

-sometimes genetically different than both parents

Explanation:

Protists are eukaryotes that cannot be classed as animals, plants, or fungi. They are quite diverse. Examples include amoeba, plasmodium, and slime mould.

Because they are so diverse, protists also have very different modes of reproduction. Some protists undergo asexual reproduction, where they simply make a copy of themselves without a mate. Others undergo sexual reproduction.

Therefore, the only option that can be correct is "-sometimes genetically different than both parents" .

If they were always genetically identical to one parent or both parents, that would mean that sexual reproduction could not be possible. If they were never genetically identical to one parent, that would mean that asexual reproduction could not be taking place.

Which of the following is not true of saliva?
cluponka [151]
The answer is <span>B. contains enzymes that begin the breakdown of proteins.

Saliva is watery substance secreted by salivatory glands. <em>It cleanses the mouth</em> and maintenance oral hygiene. <em>It moistens the food</em>, so the created food bolus could easier pass into the esophagus. It also <em>carries food chemicals to taste receptors</em> so they can be tested. It contains enzymes involved in the food digestions. Some of them are amylase, which begins the breakdown of the starch, and lipase, which begins the breakdown of triglycerides. <u>There are no enzymes in the saliva that break down proteins</u>.</span>
