Marble is a metamorphic rock.

Marble is a metamorphic rock, that forms when limestone (another rock) reaches a certain pressure and heat. It's composed of mostly calcite, and some other minerals like pyrite, quartz, iron oxide, and granite.

Over several years, marble is supposed to wear down from acid rain/weathering.

<h2>RNA Polymerase</h2>

Explanation:

  • RNA polymerase, a chemical in the cell, is  answerable for making mRNA from the  right quality. RNA polymerase is like  DNA polymerase, yet it makes a RNA strand  as opposed to a DNA strand. The promoter region of DNA Helix is attached by  RNA polymerase.
  • It pulls in nucleotides that supplement those  on the DNA strand containing the gene of interest. RNA polymerase duplicates one strand of  DNA to make a stretching bit of singlestranded  mRNA. RNA polymerase makes the  mRNA strand in what is known as the 5' to 3'  course.

How does the greenhouse effect influence the climate on earth? choose the best possible answer.
Arturiano [62]

The greenhouse effect influences climate by increasing the global temperature.

<h3>What is greenhouse effect?</h3>

The greenhouse effects are effects due to the presence of greenhouse gases in the atmosphere.

The greenhouse gases form a layer of gas in the atmosphere and prevent reflected solar radiation from escaping back into space. They, therefore, warm up the atmosphere by increasing the thermal energy.

As the concentration of the greenhouse gases in the atmosphere increases, so also is the amount of reflected solar radiation that is trapped in the atmosphere.

Therefore, an increase in greenhouse gas concentration increases the global temperature. Temperature influences other climatic factors such as precipitation.

Thus, the greenhouse effects influence climate by causing a rise in global temperature.

STALIN [3.7K]

Answer:

multicellular.

Explanation:

Organisms exhibit various levels of organization of the body. It includes cellular level, tissue level, organ level, organ system level of organization. The unicellular organisms have single cells as their bodies and therefore do not have the genes that regulate the various parts of the body rather than the individual cells. Prokaryotic are unicellular organisms only and do not have multiple cells in their bodies. Therefore, the mentioned genes are the regulatory genes that coordinate the functioning of various parts of the body of a multicellular organism. For instance, the genes involved in regulation of blood glucose levels.
