Answer:
true
Explanation:
lactase is the enzyme that leads to the hydrolisis of lactose, when lactose is present the e coli needs to hydrolyse it to simple sugars so it needs to active the gene for lactase synthesis
The rigth answer is the picture 4.
In the case of a hypotonic extracellular medium, there will be a large inflow of water to dilute the Na, thereby increasing the cell volume and there will be an explosion of the membrane in places so hemolysis, the contents of the red cell ( Hemoglobin) is released into the blood plasma.
On the other hand, in the case where the extracellular medium is hypertonic, therefore archi concentrated, well it will be the water of the red cell that will come out without damaging the membrane, we will rather have a red cell that is completely flat and non-functional without release. erythrocyte (Hb) content.
Answer:
<u>Isotonic</u>
Explanation:
If the solute concentration of the cell and that of its surrounding medium are the same there will be no net flow of water in either directions. In this case, the external solution is said to be isotonic to the cell.
Both the cytoplasm concentration and the glucose in the test tube are the same.
The answer is A.The calcium atom must bond with an atom of high electronegativity (like fluorine) because the higher electronegativity atom will bully the low electronegativity atom and take away its electrons.
These are the choices:
A. an atom with a high electronegativity, like fluorine
B. another atom with a low electronegativity, like lithium
C. another atom that would like to share electrons
D. no other atoms because it's too weak to bond with anything
So here are the answers that will complete the given statements above.
11. All of the planets in the solar system have MOONS or NATURAL SATELLITES <span>with the exception of Mercury and Venus.
12. </span>Because there is no ATMOSPHERE <span>on the moon, any liquid water would have evaporated into space long ago.
13. </span><span>The length of a planet’s day is determined by its SPEED OF ROTATION.
14. </span><span>The large, irregular objects mostly located between Mars and Jupiter are ASTEROIDS. Or in general term, it is known as the asteroid belt.
15. </span><span>Icy objects that mostly travel in long, elliptical orbits around the sun are COMETS.
Hope these answers help.</span>
