Answer:

Chemoautotrophs.

Explanation:

Autotrophs may be defined as the organism that can prepare their own food with the help of chemical and light. Two types of autotrophs are chemoautotroph and photoautotrophs.

Chemoautotrophs are the organisms that can prepare their own food with the help of chemicals. The bacteria living around deep sea and hot water vents are considered as chemoautotrophs because they prepare their food with the help of carbon present in their surroundings.

Thus, the correct answer is option (A).

Saturated fatty acids are degraded by the stepwise reactions of beta-oxidation, producing acetyl-CoA. Under aerobic conditions,
Tanya [424]

Answer:

4 ATP molecules

Explanation:

Normally, about 11 ATP molecules are generated as the result of Beta-Oxidation of saturated fatty acid in Kreb's Cycle. But the total removal of acetyl-CoA under certain aerobic condition decreases the overall yield and approximately 4 ATP molecules comes out from each removal of acetyl-CoA.

What’s vegetative reproduction (biology)<br><br> give description and example.
Virty [35]

Vegetative reproduction is a mode of asexual reproduction naturally occurring in plants. In this process. only one of the parent is involved and the offspring is genetically identical to the parent and no sharing of DNA takes place.

Examples are:  Onion, rhizome (ginger) and daffodil

Explanation:

There are meristem tissues found in the stem, root and leaves. These are undifferentiated cells and have tendency of dividing. This tissue gives rise to organs of the plant and responsible for its growth.

Natural vegetative propagation happens when an axillary bud grows into a lateral shoot and develops adventitious roots consequently forming a new plant.

Vegetative propagation can be done artificially also.

How can a rise in temperature cause a change in a polar ecosystem
Dvinal [7]

Sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.

Which of the following are compounds? (Choose all that apply.)
STatiana [176]

Answer:

Water, organic biological molecules, sodium chloride, glucose.

Explanation:

A compound is anything composed of two or more separate elements.

  • O2 and H2 are a singular elements, and a chain of carbon atoms is multiple of the same element, so these are not considered compounds.
  • Sodium chloride is sodium and chlorine, and water is oxygen and hydrogen. Glucose is a compound of sugar, and organic biological (or biomolecules) are made up of carbon and hydrogen, so these are all considered compounds

I hope this helps! Happy learning, friend :)
