Biology
1 answer:
Vesna [10]4 years ago
7 0

Answer:

1. Water(solvent) molecules travel from A across the cell membrane / semi permeable membrane to B until the concentrations of A and B become equal.2. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.3. A transport protein is a protein that serves the function of moving other materials within an organism. 

4. Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. ... transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.

Explanation:

Hope this helped I answered all of the questions.

Considering the ATP cycle, which of the following would have the most potential energy to perform work for cell activities? A. A
Mumz [18]

Answer:

ATP

Explanation:

We are well aware of the fact that ATP is considered to be the energy currency of the cell. If we talk about cell activities it needs an energy input. No doubt that H+ ions play an important role in electron transport chain step of the production of ATP, but the ultimate product which is used by the cell is ATP.

AMP and ADP are also energy sources but they contain less amount of energy as compared to ADP because in ATP there are three phosphate bonds and each bond upon breakage releases almost 7.3 kj/mol of energy. So it definitely will be more in ATP as compared to ADP and AMP.


Hope t help!

When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If
Kaylis [27]

When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If the object is slowing down, where is the energy going?

1. The potential would increase since when the ball is slowing down, its kinetic energy is being transformed into potential energy and when the ball gets hit or kicked again, it releases the potential energy and it transforms into kinetic energy.

2. The kinetic energy wouldn't exactly be lost to friction or air resistance, it's merely being converted into potential energy when the ball is slowing down due to those factors.

3. The ball returning to its natural resting state is correct since according to Newton's 1st Law in which an object that is at rest or is moving will not change unless there is another force acting upon it. in this case, the ball was kicked and there are other forces acting upon it like friction and air resistance, those factors cause the ball to slow down. Eventually the ball will stop and return to its original resting state.

4. This one is incorrect since kinetic energy is not staying the same as the person or any other force that is exerted on it be increased therefore increasing the kinetic energy.

What is the full form of tree​
Rudik [331]

Explanation:

A tree or large tree is called a long-standing woody plant. In botany, the tree is one of the most durable plants that maintains its leaves by growing a stem or trunk. In some definitions, the use of the tree is such that it is the only woody plant. It is the only plant from which wood is obtained. It is not possible to determine the exact height of the trees, but overall the adult trees reach at least 6 meters [citation needed]. In the structure of the tree there are usually branches that are attached to a large trunk. Compared to other plant and animal species, trees have a long life. Some species of trees are more than 100 meters tall, and some live for thousands of years. Trees are important elements of natural landscape, gardening and landscaping. [1]
