Answer:

1) Water pressures lower than the rock pressure cause metamorphic reactions to run at lower temperatures.

2) Water facilitates the transfer of ions between minerals and within minerals, and therefore increases the rates at which metamorphic reactions take place. So, while the water doesn’t necessarily change the outcome of a metamorphic process, it speeds the process up so metamorphism might take place over a shorter time period, or metamorphic processes that might not otherwise have had time to be completed are completed.

3) Water, especially hot water, can have elevated concentrations of dissolved substances, and therefore it is an important medium for moving certain elements around within the crust. So not only does water facilitate metamorphic reactions on a grain-to-grain basis, it also allows for the transportation of ions from one place to another. This is very important in hydrothermal processes, which are discussed toward the end of this chapter, and in the formation of mineral deposits.

The nucleus has a system of _____ embedded within its outer membrane which allows communication between the nucleus interior and

Bumek [7]

Answer:

pores

Explanation:

The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by nuclear pore complex. It allows the pore to regulate the movement of molecules between the nucleus and the cytoplasm. It allows small particles to pass through such as ribosomal proteins. It prevents most large particles (except for histone) from passing through; thus, it is selective in nature. This function of the pores clearly shows that it allows communication to occur between the nucleus interior and the cytoplasm.

Explain the central dogma of molecular biology. please don't define it or state what it says.

katen-ka-za [31]

Answer:

The central dogma of molecular biology is an explanation of the flow of genetic information within a biological system. it is often stated as "DNA makes RNA, and RNA makes protein", although this is not its original meaning.This states that once "information" has passed into protein it cannot get out again.

How do I calculate a heart rate?

olga_2 [115]

Explanation:

To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery — which is located on the thumb side of your wrist. When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate your beats per minute.
