How does the water get to the leaves in the tops of the tallest trees against the force of gravity?

Answers

Answer 1
Answer: Water gets to the leaves in the tops of the tallest trees by something called the cohesion-tension theory. Water has two very unique properties called adhesion and cohesion. Cohesion is the tendency of water molecules to stick together with one another. The water sticks together, leaving no room for air, strengthening the "force" of the water going up the tree. The water also sticks to the sides of the xylem inside the tree. In addition to these properties, there are also the factors of negative and positive water potential. For more information, look up more details of the cohesion-tension theory.

16) __________ memory holds information for 15 to 25 seconds and stores it according to its meaning rather than as mere stimulation.a. Sensory
b. Processing
c. Short-term
d. Long-term

Answers

Short-term memory holds information for 15 to 25 seconds and stores it according to its meaning rather than just as mere stimulation. However, it is not really true that short-term memory can be retained only for this short amount of time. It has been shown in different studies that it can be held even longer. 

Most living things need oxygen to survive. You breathe in oxygen and it is carried to this organ. Here the red blood cells pick up the oxygen and carry the oxygen to all the body cells that need it. What is this organ?A) diaphragm
B) heart
C) lungs
D) trachea

Answers

Answer:

The correct answer would be the C) lungs.

Lungs are the pair of air-filled spongy organs.

They are mainly associated with the exchange of gases (carbon dioxide and oxygen) in the body.

The alveoli are the group of tiny air-sacs present in the lungs which form the site of gas exchange.

The oxygen from the alveolar site diffuses into the blood and carbon dioxide from the blood diffuses into the alveolar site.

The oxygen is then transported to all cells of the body with the help of circulatory system whereas carbon dioxide is removed out of the body as a part of exhaled air.

C) the lungs.
The air moves down the trachea and into the lungs where it is picked up by the blood

A patient is in need of hydration. Which type of solution are the patient’s cells most likely in

Answers

If a patient is in need of hydration then it implies that initially the patient's cells were in a hypertonic solution and their internal cell's environment was hypotonic. A hypotonic solution is a solution which has low solute concentration which results in lower osmotic pressure. In such condition, solvent moves from high concentration towards lower concentration through a semi permeable membraneby osmosis so as to make osmotic pressure equal on both the sides. So, when the patient's cells were kept in a hypertonic solution their cell's water moved outside and they became dehydrated. This is the reason why they need to be rehydrated to be normal again. Cells which become dehydrated are also known as flaccid cells whereas cells which have higher solvent concentration than the environment are also known as turgid cells.

Answer:

hypotonic

Which of the following happens when a phosphate-phosphate bond in an ATP molecule is broken

Answers

Energy is released in a cell as a result of the ATP phosphate-phosphate link being broken. The correct option is B.

What is ATP?

A chemical that is a part of all livingcells and gives energy to a variety of metabolic processes, including the production of RNA.

In patients with advanced solidtumors, the effects of laboratory-produced ATP on weight loss and muscle strength are being investigated. Likewise known as adenosinetriphosphate.

An organic substance called adenosine triphosphate powers a variety of biological functions in living cells, including muscularcontraction, nerve impulse transmission, condensate dissolving, and chemical production.

The breakdown of the ATP phosphate-phosphate connection causes energy to be released in a cell.

Thus, the correct option is B.

Your question seems incomplete, the missing options are:

Lysosome contents are released in a cell.

Energy is released in a cell.

Water is transported into an animal cell

Light energy is absorbed in a plant cell.

ATP stands for Adenosine Tri-Phosphate and it consists of three inorganic phosphates and an adenosine molecule. When ATP breaking down to ADP, the energy is released from the breaking down of a molecular bond and this energy is used to our daily operations.
