Answer: Option B

Explanation: The classification of rocks is done by studying about the texture, color and layers.

The texture of the rock can be defined as the minerals grains that constitute to form a rock. The grain vary in size and shape.

The color of different rocks differ and layers also differ based on the type of rock.

As the composition of metamorphic, sedimentary and igneous rock are different, their texture, color and size do differ. By examining these factors rocks can be differentiated.

If autotrophs had not evolved on the primitive earth, then the heterotrophs would have probably have exhausted the:________.a. a

lapo4ka [179]

Answer:

C. Oxygen supply

Explanation:

Autotrophs make their own food with carbon dioxide and create oxygen as a byproduct. Heterotrophs need oxygen to create energy and create carbon dioxide as a byproduct. Therefore, if there are no autotrophs, the carbon dioxide in the air won’t be able to be used to turn to oxygen, which heterotrophs need. The heterotrophs will use up all of the oxygen in the air, leaving lots of carbon dioxide behind. This is why we need plants and trees! Thus, the answer is C.

I hope this helps! :)

TCS is an acronym for Tata Consultancy Services and it is a multinational IT services, consulting and business solutions company that was established on the 1st of April, 1968 in Mumbai, India. Also, TCS has a large network of initiative (technology), innovation and delivery centers across the world.

In 2013, TCS was deeply invested in harnessing renewable energy to generate electrical energy and reducing the emission of carbon, especially by developing solar energy. Thus, solar product solutions such as solar water heaters and lighting systems were installed in some of its offices because they were economically viable and would help meet their energy needs.

In conclusion, solar water heaters was the initiative (technology) that helped harvest renewable energy in some TCS offices.

Cells that are terminally differentiated:_________

Tom [10]

Answer:

b. can no longer undergo cell division.

Explanation:

Terminally differentiated cells are those cells completely specialized in their functions that have lost their ability to proliferate. They are cells that have a unique, very specific, function, whereas undifferentiated cells do not have specialized functions that serve to replace old and dead cells. Examples of terminally differentiated cells include skin cells derived from epithelial stem cells, red blood cells and white blood cells generated from hematopoietic stem cells, etc.
