Answer:
Human lung capacity can be measure in several ways. One way is by using a piece of laboratory equipment called a respirometer or spirometer. A less accurate (but very sanitary) method to measure lung capacity is by using a balloon. Procedure A: VITAL CAPACITY 1. Blow up the balloon several times to stretch it before beginning to take measurements.
Explanation:
Recombinant DNA (rDNA), or molecular cloning, is the process by which a single gene, or segment of DNA, is isolated and amplified. ... A cloning vector is a DNA molecule that carries foreign DNA into a host cell, where it replicates, producing many copies of itself along with the foreign DNA.

Question options:
1. Placing a red blood cell in distilled water
2. Placing a red blood cell into an isotonic solution
3. Placing a red blood cell into a hypotonic solution
4. Placing a red blood cell into a hypertonic solution.
5. Placing a red blood cell with a concentration of 0.9% NaCl into a solution of 1.5% NaCl
6. Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
Answer:
Crenation (shrinking):
-Placing a red blood cell into a hypertonic solution.
-Placing a red blood cell with a concentration of 0.9% NaCl into a solution. of 1.5% NaCl
Hemolysis (swelling):
-Placing a red blood cell in distilled water.
-Placing a red blood cell into a hypotonic solution.
-Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.
No change:
-Placing a red blood cell into an isotonic solution.
Explanation:
Crenation is an osmotic process in which blood cells shrink while placing <u>hypertonic</u> or alkaline solutions. Hemolysis is the destruction of red blood cells in which cells bloat up and may explode while placing in a<u> hypotonic</u> or acidic solution. The blood cells have no change In an <u>isotonic</u> environment because the relative concentrations of solute and water are equal on both sides of the membrane.
Answer:
The source of life for fetus is the placenta which is connected by the umbilical cord.
Explanation:
The placenta is a temporary organ that during pregnacy connects the fetus and the mother trough the umbilical cord. It allows the fetus to recieve nutrients. It also helps to produce gas exchange, waste elimination and thermoregulation.
Placenta also participate as an endocrine organ (releasing HCG, Progesterone, Estrogen, human placental lactogen) and an immunity organ (allowing IgG antibodies to pass through).
