The following tests can determine the mineral in a rock specimen:

1. How does the rock crumble or split under pressure?

2. What is the texture of the rock?

3. Observing it under a magnifying lens.

4. Determine the color of the rock



Test 1 and 3 determines if the rock is granular and the types of grains in the rock. Test 3 also determines if the rock has layers hence sedimentary rock.

Determining whether color of the rock is dark or light also helps identify the mineral and type of rock.

Plasma contains more sodium than chloride. How can this be if individual ions of sodium and chloride exactly balance each other
MAXImum [283]

In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.

So this is how plasma is electrically neutral.

<h3>The makeup of bodily fluids:</h3>
  • High levels of sodium, chloride, bicarbonate, and protein can be found in the plasma.
  • High levels of salt, chloride, and bicarbonate but a relatively low level of protein can be found in the IF.
  • The ICF, on the other hand, contains higher levels of protein, phosphate, magnesium, and potassium.
<h3>What occurs when the plasma Na+ content rises?</h3>
  • Although the plasma sodium concentration does not provide any information regarding the volume of extracellular fluid, it does allow for an assumption regarding intracellular volume.
  • A rise in plasma sodium (plasma osmolality) causes water to be drawn out of the cell, which causes the intracellular volume to decrease.
<h3>Why does plasma have a higher sodium content than chloride?</h3>
  • In plasma, sodium predominates over chloride.
  • In addition to chloride, there are other negatively charged molecules in plasma.
  • The extra sodium restores the balance of the overall negative charges.

Which statement is the best physical description of a gene? A chromosome is a segment of a gene. Genes carry many chromosomes. A
Sergio039 [100]

Answer:

The correct option is <em>C. A gene is a specific segment of DNA on a chromosome</em>

Explanation:

Option A is false because a gene is a segment on a chromosome.

Option B is false because a chromosome carries many genes.

Option D is false because a gene carries a segment of DNA, not all of the DNA.

Option C is correct because there are many genes present on a single chromosome. Each gene carries a segment of DNA. The position of a gene on the chromosome is known as its loci.

An example of a communicable disease is
qwelly [4]
A communicable disease is one that is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.

Reporting of cases of communicable disease is important in the planning and evaluation of disease prevention and control programs, in the assurance of appropriate medical therapy, and in the detection of common-source outbreaks. California law mandates healthcare providers and laboratories to report over 80 diseases or conditions to their local health department. Some examples of the reportable communicable diseases include Hepatitis A, B & C, influenza, measles, and salmonella and other food borne illnesses.
