Answer: Schist and gneiss

Explanation: The rocks that forms at the highest pressure and temperature condition are Schist and Gneiss, where Gneiss being the highest grade metamorphic rock.

Schist is mainly comprised of quartz, some feldspars and platy minerals such as biotite and muscovite and are foliated rocks with a distinct cleavage commonly known as the schistocity.

Gneiss is mostly composed of quartz, hornblende, feldspar and mica. It has a distinct alternating bands of light and dark colored minerals. The minerals in the darker band contains hornblende, mica and garnet. The lighter band contain minerals such as feldpar and quartz. This banding has a significant characteristic for defining a gneissic rock.

Hi everyone

Amino acids are acids on one hand, and a base on the other hand.

An acid is a substance that produces hydrogen or hydroxonium ions as the only positively charged ion when it ionizes.

All amino acids have an amine group - $NH_2$ and a carboxylic group - $COOH$ .

The carboxylic group ionizes such that:

$COOH -- > COO^- + H^+$

The presence of the amine group enables amino acids to also act as a base.

Imagine that zika virus has a 1% incidence in the population. A test for the virus has a 3% false positive rate and no false neg

Darina [25.2K]

Answer:

The answer is 97%.

Explanation:

The zika virus' 1% incidence rate in the population has no effect over the probability of the patient being infected or not. If the test has a 3% false positive rate that means that if it is positive, the results have a 97% chance of being true. Therefore the chance that the person who took the test and had a positive result being actually infected is 97%.

I hope this answer helps.

Which of the following does NOT characterize proteins?

8090 [49]

Answer:

The answer is C) They appear to be the molecular carriers of coded hereditary information.

Explanation:

Why NOT C) They appear to be the molecular carriers of coded hereditary information?

This is the job of the nucleic acids. It is composed of nucleotides which are the basic units of DNA and RNA. They carry genetic information about a certain organism.

<h3 /><h3>True of proteins:</h3>

A) They may be denatured or coagulated by heat or acidity.

Denaturation is the destruction of the protein's secondary and/or tertiary structures. The primary structure is not disrupted due to the tough peptide bonds and can only be broken down by acid. For heat denaturation, hydrogen bonds are destroyed, as in cooking of egg whites and medical equipment sterilization.

B) They have both functional and structural roles in the body.

There are many kinds of proteins that have functional and structural roles like hormones (FSH, LH), antibodies (IgA, IgM), enzymes (lipase, amylase), for storage/transport (hemoglobin, ferritin), and locomotion (actin, troponin).

D) Their function depends on their three-dimensional shape.

Just like hemoglobin, it's quaternary structure can carry 4 molecules of iron in one go. Enzymes are shaped accordingly to fit a specific substrate (lock-and-key model)
