You observe every fall that the trees in the forest lose their leaves, but by the following fall, the leaves have disappeared. The most accurate explanation for this observation would be:

Answers

Answer 1
The tree produces a layer called abscission layer, in which nutrients and water are prevented from reaching the tree which stops the leaves from growing
Answer 2

The tree creates a layer known as the abscission layer, which prevents nutrients and water from reaching the tree and inhibits the growth of the leaves. Hormones in the trees cause the process of abscission.

What is abscission layer?

Tiny tubules in the abscission layer are responsible for carrying carbohydrates back into the tree and delivering water to the leaf, flower, or fruit.

The amount of nutrients and water that pass through the tubes is decreased in the autumn because cells in the abscission start to expand and exude a waxy substance.

Abscission of leaves, which takes place in the fall, is the natural loss of an old leaf at the base of the petiole. Many physical and biochemical changes occur during leaf abscission, most of which are controlled by plant hormones.

Therefore, every fall that the trees in the forest lose their leaves.

What is Plasma membrane?

Plasma membrane also known as cell membrane is a membrane found in all cells that separates the interior of the cell from the external environment. The plasma membrane consists of a lipid bilayer that is semi-permeable that regulates the transport of materials entering and exiting the cell.

This membrane is called a selectively permeable membrane because it controls the movement of substances in and out of the cell, which means that the plasma membrane allows certain materials to pass through it, while at the same time it prevents other materials from entering through it. Plasma membrane is dynamic in nature.

Thus, Dynamic term describes the plasma membrane. So, the correct option is (B).

In a particular population, the allele frequency of the ABO blood type alleles are as follows: IA is 20%, IB is 30% and i is 50%. If mating is random and the population is in Hardy-Weinberg equilibrium, what percentage of the population will have type O blood type

Answers

Answer:

The genotypic frequency F(ii) = 0.25 = 25%

Explanation:

Due to technical problems, you will find the complete explanation in the attached files

In the blood type cases involving the ABO group, the type of inheritance here is the co-dominance type of inheritance

The percentage of the population with type O blood will be 25%

Type A (IA) is dominant to type O (i) and at the same time type B (IB) is also dominant to type O (i).Using the equation - p² + 2pq + q² + 2pr + r² + 2qr = 1Where indicates the genotypic frequency with type A (AA) blood and indicates genotypic frequency of BB and indicates the genotypic frequency of OO.

Since we are finding the percentage with type O blood (r²) where r (allelic frequency of type O) is 0.5 (50%)

= 0.5² = 0.25 = 25%.

Which is one reason for the formation of global winds? (1 point)
-uneven heating of Earth's surface
-fewer daylight hours in Arctic regions
-loss of energy as warm air rises
-condensing of moisture in cooling air

Answers

One reason for the formation of global winds is the uneven heating of the Earth's surface.

The uneven heating of the Earth's surface is primarily caused by variations in solar radiation received at different latitudes.

The equator receives more direct sunlight when the sun's rays strike the Earth's surface, they heat the air in contact with it. n the poles, resulting in a temperature gradient across the planet. This temperature gradient drives the formation of global winds.

Fewer daylight hours in Arctic regions: This option is incorrect. The number of daylight hours in a region does not directly contribute to the formation of global winds. While sunlight does play a role in heating the Earth's surface and driving atmospheric circulation, the length of daylight hours is not a determining factor.

Loss of energy as warm air rises: This option is valid. As warm air rises due to heating from the Earth's surface, it expands and cools. This cooling causes the air to lose energy, and as a result, it becomes denser and sinks back toward the surface. This sinking motion creates regions of high pressure, which contribute to the formation of global winds.

Condensing of moisture in cooling air: This option is incorrect. The condensation of moisture in cooling air relates to the formation of clouds and precipitation, but it does not directly influence the formation of global winds.

Therefore, the uneven heating of the Earth's surface, due to variations in solar radiation, is a significant reason for the formation of global winds.

Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?
A. a caliper and a flask
B. a stopwatch and a beaker
C. a balance and a beaker
D. a meter stick and a temperature probe

Answers

Answer:  C. a balance and a beaker

Explanation:

A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.

The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.

To get the density, you divide the mass over volume.

For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.
