How do autotrophs obtain energy? How do heterotrophs obtain energy?

2 answers:

Autotrophs, by definition, are organisms that are able to internally manufacture their own food. Autotrophs, also known as producers, are organisms that obtain their energy by converting light energy into chemical energy, via photosynthesis. Photosynthesizing plants are an example of autotrophs.

Heterotrophs, by definition, are organisms that are unable to internally manufacture their own food. Heterotrophs, also known as consumers, are organisms that obtain their energy by consuming other organisms. Humans are an example of heterotrophs.

Autotrophs obtain energy by harnessing the sun's energy through photosynthesis. Heterotrophs obtain energy by consuming the organic matter of other organisms.

Why are subduction zones not commonly found at convergent continental-continental boundaries?

Ede4ka [16]

Answer:

the subduction zone is commonly found in convergent continental-continental boundaries since it is where two continental crusts meet, and the force forces one crust to subduct under another one.

Hershey and Chase used a DNA-based virus for their work. How might the results have been different if they had used an RNA virus

4vir4ik [10]

Answer:

The correct answer is c.With an RNA virus, radioactive RNA would have been in the final pellet.

Explanation:

Hershey and Chase infected<em> E.coil</em> with bacteriophage which was having DNA as its genetic material. The bacteriophage was labeled with radioactive sulfur and radioactive phosphorus and it was radioactive phosphorus that was found in the bacterial cells or pellet.

As because DNA contains phosphorus, not protein therefore they it was proved that DNA is the genetic material. Similarly, RNA is also a nucleic acid which is genetic material for many viruses and contains phosphorus.

So if Hershey and chase might have chosen an RNA virus then radioactive RNA would have been present in the pellet. So the correct answer is c.

Which of the following is the only marsupial found in North America?

Kamila [148]

<span>The opossum is the only marsupial found on North America. It is found in many locations and is fairly commonly seen rummaging through waste and other leftover areas looking for things to scavenge. Opossums are known for taking any opportunity it can to find waste products and eat them.</span>

A group of students wanted to compare the rate of respiration in four different fruits, as well as in tomatoes.

Brilliant_brown [7]

In this case, the dependent variable is the rate of respiration, the independent variable is the type of plant (either fruit or tomatoes), whereas a fixed variable may be the temperature.

<h3>What is a dependent variable?</h3>

A dependent variable is any type of experimental condition that is modified during the experiment.

Conversely, independent variables do not change along the experimental procedure (e.g., type of plant).

Finally, a fixed variable, also known as a control variable, is any condition that remains stable during the experimental procedure (in this case, for example, room ambient temperature).

In conclusion, the dependent variable is the rate of respiration.
