Which statement about the difference between autotrophs and heterotrophs is true? Autotrophs transform radiant energy into chemi

cal energy, but heterotrophs can’t. Autotrophs take in only oxygen, but heterotrophs take in both oxygen and carbon dioxide. Autotrophs have two different electron transport systems, but heterotrophs have none. Autotrophs don’t have a Calvin cycle, but heterotrophs do.

Answer: A) <span>Autotrophs transform radiant energy into chemical energy, but heterotrophs can’t.

-------

Autotrophs are producers and can produce their own food, usually using sunlight. Heterotrophs cannot produce their own food and depend on autotrophs for food. 

Since sunlight is a form of radiant energy, and autotrophs use sunlight to make food (which is/can be chemical energy), the first choice is true.

The second choice is not true because autotrophs use carbon dioxide to produce food. The third choice is not true because some heterotrophs use an electron transport system in their </span>mitochondria to generate ATP. The fourth choice is not true because the Calvin cycle is a step of photosynthesis, which is a process used by autotrophs, so they must have a Calvin cycle.

Which organelle contains DNA and controls the activity in the cell?<br> ОВ<br> Ос<br> OD<br> ОЕ
IrinaK [193]

Nucleus can be defined as a large organelle found in the Eukaryotic cells and it is also  know as the cell's command center,thus it controls the activity of the cells

Explanation:

  • The answer to the above question is (c )nucleus. During the cell cycle the nucleus of the cell mediates the replication of the of the DNA and controls the gene expression.
  • The nucleus contains a structure which is known as nucleolus and which is made up of protein and ribonucleic acid(RNA)

Suppose i needed to measure exactly 15.0 mL of water for an experiment. Which graduated cylinder would be the best one to use, a
attashe74 [19]

Answer:

A test tube would be used

Explanation:

The test tube refers to a laboratory device that is made of graduated glass for which cylinder used to measure small quantities of liquids that is from 5 mL to 2 L. The most suitable type of specimen must be chosen for measuring the liquid volume, in this situation that is a 15 mL. The specimen is shutdown to lower and has a support base.

Therefore the correct answer is a test tube.

How might retaining too much heat be a disadvantage to an organism?
Ierofanga [76]

Answer:

<u>Too much heat can disrupt subcellular structures such as membrane proteins, and enzymes while damaging the integrity of the plasma membrane.</u>

Explanation:

Proteins are macromolecules made up of amino acids. These fold and bond to form several biologically important molecules. For instance, enzymes, a special type of protein functions by <em>providing alternative reaction pathways. They work best at a specific pH and </em><em>optimal temperature range</em><em>, beyond which they become non-functional  or denatured entirely. </em>

The denaturing of proteins occur at high temperatures, and alter protein folding, bonding and other types of behavior. Furthermore, membrane proteins are  important for regulating cell function. If these are disrupted, the system cannot maintain homeostasis i.e a constant internal environment.
