The process where liquid turns to vapor is called evaporation.

The answer would be:

Evaporation

If you'd like to know more about this, read on:

Evaporation is the process where a substance in a liquid state is changed to a gaseous state. This occurs when there is an increase in temperature or pressure. When water gains a lot of heat, it changes to gas in the form of vapor. The amount of vapor depends greatly on the amount of water present. For example, in a desert, you might think that there is a lot of evaporation going on, but the answer is no. This is because there is not much water present.

3. In tropical regions,

marin [14]

Answer:

a, a permanent thermocline traps nutrients in the deep water

b. primary productivity is high all year round, because there is a constant supply of solar energy for photosynthesis.

Explanation:

Thermocline occurs in the tropical regions because the temperature is very high which warms the upper layer of water bodies whereas the lower layer of water has low temperature due to no sunlight. The primary productivity is high all year in the tropical regions, because there is a constant supply of sunlight that is needed by the plants for preparing their own food.

An orange might roll off your cafeteria tray when you stop suddenly because of A. the balanced forces acting on the orange. B. t

kramer

D is correct. Newton's first law of motion states that an object in motion stays in motion. The orange is moving and then the tray stops making the orange move forward because of inertia. Hope this helps! ;)

Hexokinase can use glucose or fructose as a substrate. The Km forglucose is 0.15 mM and for fructose Km = 1.5 mM.

babymother [125]

Answer:

a) glucose because Km is less for glucose.

b) For glucose, V as a percentage of Vmax = 50 %

For fructose, V as a percentage of Vmax = 9 %

Explanation:

a) Hexokinase has highest affinity for glucose because it's Km for glucose is low.

When enzyme [E] binds a substrate [S] an [ES] complex is formed. It is represent as under:

[E] + [S] ⇌ [ES] ⇌ [E] + [P]

As soon as [ES] is formed it may either form [E] & [P] in a forward reaction or dissociate back into [E] & [S]. Km is known as dissociation constant which represents the extent to which [E] & [S] are being formed. A higher value of Km represents formation of more [E] & [S] back from [ES]. It also means that binding affinity of enzyme with substrate is less or we can say that Km is inversely proportional to binding affinity.

Km ∝ 1 / binding affinity.

So, it simply means that lower the Km more will be the affinity of the enzyme for the substrate. In the given question, Km for glucose is 0.15 mM which is less than fructose (Km for fructose = 1.5 mM) that is why glucose is the answer.

b) The formula for Michaelis–Menten equation is as under:

V = Vmax × [S] / ([S] + Km)

V / Vmax = [S] / ([S] + Km)

Here, for glucose Km = 0.15 mM and [S] = 0.15mM.

So V as a percentage of Vmax for glucose will be as under:

V / Vmax = 0.15/0.15 + 0.15

→ V / Vmax = 0.15/0.30

→ V / Vmax = 0.5 = 1/2 = 50 %

Here, for fructose Km = 1.5 mM and [S] = 0.15mM.

So V as a percentage of Vmax for fructose will be as under:

V / Vmax = 0.15/0.15 + 1.5

→ V / Vmax = 0.15/1.65

→ V / Vmax = 0.09 = 9/100 = 9 %

Briefly describe the major steps of the mechanism of how a competent bacterial cells becomes transformed, beginning with the bin

Mrrafil [7]

Answer:

The steps can be the following:

1. Free DNA fragments from the donor cell bind to the recipient cell.

2. A DNA strand is digested by the bacterial nuclease and the excess strand is absorbed.

3. The coated DNA and the DNA of the recipient cell are brought together to achieve a homologous sequence.

4. DNA base pair alignment occurs through DNA ligase.

5. The integration of the exogenous DNA resulting from the recombination is completed, completing the transformation.

Explanation:

Transformation can be said to be the genetic variation of a cell that results from the uptake, incorporation and expression of exogenous DNA from its environment, which is absorbed by the cell membrane. The recipient bacteria have to be in a state of competition, and this type of competition can be induced in a laboratory, so that the bacterial cell is permeable to DNA when exposed to certain conditions. For this, the cells are incubated in a solution that has various divalent cations, such as calcium chloride, before exposing them to thermal shock. The main function of calcium chloride is to alter the cell membrane, allowing the recombinant DNA to enter the host cell. These types of cells can be called as competent cells.
