What kind of mixture is a solution a suspension? a colloid?

1 answer:

8 0

Mixtures are combinations of several substances. Each of the substances retains its physical properties. There are no new substances created. This is in contrast to a chemical reaction in which two or more reactants make new products.

There are two types of mixtures. The first kind of mixture is a homogenous mixture. Homogenous mixtures are uniform in the ratio of the combination of substances. throughout. All solutions are homogenous mixtures. Colloids (such as mile) and suspensions are also homogenous mixtures, but their particle sizes are larger than the particles that make up a solution. This larger particle size makes colloids and suspensions appear murky or opaque.

The second kind of mixture is a heterogeneous mixture. Heterogeneous mixtures are not uniform throughout. A classic example of a heterogeneous mixture is a trail mix- every handful you grab will be slightly different. If a suspension is allowed to sit, then its large particles will settle to the bottom of its container. At this point, the suspension would be classified as a heterogenous mixture.

What would be the most likely effect on the transcription of the trp structural genes for the mutation scenarios provided? mutat

blagie [28]

Answer:

I've responded to each scenario individually, please see below:

1. mutation that prevents ribosome binding to the mRNA

No transcription occurs

2. 5' UTR mutation that changes region 1 tryptophan codons into alanine codons

Transcription when alanine is low

3. mutation that creates a stop codon in region 1 of mRNA 5' UTR

Transcription occurs, a truncated protein will be made during translation

4. deletions in region 2 of the mRNA 5' UTR

Transcription occurs, region 1 and 2 might get paired together

5. deletions in region 3 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

6. deletions in region 4 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

7. deletion of the string of adenine after region 4 of the mRNA 5' UTR

Transcription occurs, however, it will not be as stable a molecule because of losing its polyA tail

Hope that answers the question, have a great day!

Aldosterone ________. A) is secreted by the posterior pituitary B) functions to increase sodium reabsorption C) presence increas

Vesnalui [34]

Answer:

Option B) functions to increase sodium reabsorption.

Explanation:

Aldosterone is an hormone secreted by the cortex of the adrenal gland. The adrenal gland is situated at the superior poles of the right and left kidneys.

Aldosterone regulates sodium homeostasis and as such helps to control blood volume and blood pressure.

Aldosterone is secreted in response to decreased blood pressure (hypotension) to increase sodium reabsorption from urine, sweat, and the gut. Also excessive aldosterone levels (too high sodium) can lead to high blood pressure (hypertension).

During protein synthesis, the peptide bond between amino acids is formed by the process of _____.

taurus [48]

<span>During protein synthesis, the peptide bond between amino acids is formed by the process of condensation. Condensation is a reaction when two smaller molecules (in this case amino acids) make a larger molecule(protein) and water as a side product.</span>
