What type of rock can melt under the right conditions?

Answers

Answer 1

Answer: To tell you the truth, all rocks can melt under heat and pressure. For example, if a volcano erupts, the magma that is flowing can melt the rocks because of extreme heat.

What's so the "Central dogma" or sequence of information flow in Turing genes into proteins?

Answers

Basically it involves translations:
Once you have your mRNA (which now only has exons) it then binds with rRNA (ribosomal RNA)
It reads a start codon, and then the tRNA reads a complimentary anticodon which codes for a specific amino acid.
Essentially the amino acids then interact elongate, and then you have a long chain of amino acids (primary structure of a protein)

Then there is a lot of folding, di-sulfide bridges and other interaction that then make the amino acids into a protein like haemoglobin (red blood cell)

How did the geocentric theory change over time as increased scientific knowledge led to increased consensus within the scientific community?a.Scientists demonstrated that Earth revolves around the sun.
b. Scientists proved that Earth was the center of the universe.
c. The sun began to rise in the east several centuries ago.
d.The observations for a geocentric solar system became increasingly well documented.

Answers

The way how the geocentric theory change over time as increased scientific knowledge led to increased consensus within the scientific community is a.Scientists demonstrated that Earth revolves around the sun. This event was the best supporting detail which led scientific community to change their views and made them make a huge step towards future.

Answer: b

Explanation:

The Krebs cycle takes place within the:A. mitochondria
B. lysosome
C. vacuole
D. cytoplasm

Answers

Answer: A. mitochondria

Explanation:

The Krebs cycle is the set of reactions that drives to the complete oxidation of glucose. This occurs in the matrix of eukaryote mitochondria and the prokaryotyc cytoplasm. The main reagents of the Krebs cycle are acetate in the form of acetyl-CoA, water, and electron carriers. The main reagents of the Krebs cycle are acetate in the form of acetyl-CoA, water, and electron carriers. Reactions are catalyzed by enzymes where decarboxylases stand out (decarboxylation catalysts) and dehydrogenases (oxidation-reduction catalysts) leading to the formation of NADH).

The Krebs cycle occurs in the mitochondrial matrix (mitochondria) and generates a pool of chemical energy (ATP, NADH, and FADH2) from the oxidation of pyruvate, the end product of glycolysis.

Onion root tips are often used to study mitosis because they grow very rapidly, which means that many cells are dividing. The very tip of the onion root ends in a structure called the root cap. The other end of the root attaches to the onion. A scientist is interested in determining whether an onion root tip grows from the base of the root or from the tip near the root cap. She counts the number of cells that are in one of the phases of mitosis at different distances from the root cap. What is the dependent variable in her experiment

Answers

Answer:

- Dependent variable: number of cells that are in one of the phases of mitosis

Explanation:

In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.

Which of the following materials is damaged by acid rain? quartz marble aluminum glass

Answers

The material that is damaged by acid rain is marble.

Answer:

Option B, Marble

Explanation:

Limestone or marble is severely affected by the acid. Acid rain causes corrosion of all building and sculpture that are made up of marble. The sulphuric and nitric acid in the acid rain reacts with the calcite in the marble to dissolve it. This leads to peeling of marble structure which further exposes black crust made of gypsum formed by the reaction between calcite, water and sulphuric acid.
