from what stucture does a pollen grain develop​

Answer:Cytokinesis is the process whereby the cytoplasm of a parent cell is divided between two daughter cells produced either via mitosis or meiosis. ... Cytokinesis begins in anaphase in animal cells and prophase in plant cells, and terminates in telophase in both, to form the two daughter cells produced by mitosis

Answer:

D. Toy pulls on the child in the opposite direction

Explanation:

Newton third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object 1 exerts a force (action force) on another object 2, object 2 exerts a force (reaction force) of equal magnitude but opposite direction on object 1.

According to this question, a child pulls a toy across the floor. Based on Newton third law described above, the toy will pull the child with an opposite force that is equal in magnitude. Hence, the equal and opposite force is: Toy pulls on the child in the opposite direction.

Answer:

D) The number of mitochondria has decreased due to long period of rest

You are correct :)

Explanation:

The basketball player requires energy so remember that the mitochondria is the powerhouse of the cell (so it produces energy).

The question is incomplete, the complete question is;

complete the half reactions for the cell shown here and show the shorthand notation for the cell by dragging labels to the correct position. The electrode on the left is the anode, and the one on the right is the cathode.

in the left side there is a solution of Pbcl2(s) and it contains the elctrode pb and on the right side there is solution of AgCl(S) which contains the electrode Ag. There is inverted glass tube with Kcl (aq) on the left and and Kcl(aq) on the right.

Anode half-reaction:

Blank + 2Cl^- equilibrium arrow yields Blank + 2e^-

Cathode half reaction:

Blank +2e^- equlibriums arrow yields Blank + 2Cl^-

Shorthand notation: Please provide.

Answer:

Explanation:

Let us remember that oxidation occurs at the anode while reduction occurs at the cathode. This will guide our work here. The Pb(s)/Pb^2+(aq) is the anode while the Ag^+(aq)/Ag(s) is the cathode

Anode half-reaction:

Pb(s) + 2Cl^- ⇄  Pb^2+(aq) + 2e^-

Cathode half reaction:

2Ag^+(aq) + 2e^- ⇄  2Ag(s) + 2Cl^-

Overall reaction equation;

Pb(s) + 2Ag^+(aq)  ⇄ Pb^2+(aq) + 2Ag(s)

Shorthand notation;

Pb(s)/Pb^2+(aq)//Ag^+(aq)/Ag(s)

Answer:

General Adaptation Syndrome (GAS)

Explanation:

It is a theory that describes the stages of physiological changes that a body experiences when under stress. The three stages in order are:

The alarms stage

The resistance stage

the exhaustion stage

(This was paraphrased in my own words so that it can be paraphrased again by you)

The process that describes the body's natural physiological response to stress is known as the general adaptation syndrome.

It is either emotional or physical. Stress is any event or thought that generates the feeling of irritation, anger, or nervousness.

The body responds to stress with a physiological response that is known as the "general adaptation syndrome."

It has three stages:

Adult males require between 2,000 and 3,000 calories per day, whereas adult females require between 1,600 and 2,400 calories daily. Thus, option A is correct.

Keep us alive and make sure our organs are functioning properly, our bodies require energy. We give our bodies energy when we eat and drink.

Our daily activities, such as breathing and jogging, cause our bodies to expend that energy.

A calorie deficit is necessary for weight loss, but how much of one depends on your age, weight, health, and goals. It's frequently advised to reduce daily caloric intake by roughly 500 calories.

Answer:

Explanation:

As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow. More and more heat and water will be pumped into the air. The pressure at its core will drop further and further, sucking in wind at ever-increasing speeds. Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.
