Which important phenomena occur in plant leaves and help water transportation in xylem tissues?

algol13

The answer is C. The phenomena occur in plant leaves and help water transportation in xylem tissues is photosynthesis and transpiration. A balance between these two phenomena is important to maintain balance in the plant's life.

portion of the serous membrane that covers and adheres to the lung is called the ________. The portion of the serous membrane th

natulia [17]

<h2>Visceral pleura</h2>

Explanation:

The portion of the serous membrane that covers and adheres to the lung is called visceral pleura

Pleura are the pair of membranous linings surrounding the lungs
The visceral pleura covers each lung surface, and the parietal pleura covers the inner surface of the thoracic cavity
The visceral pleura is a delicate membrane which dips into the fissures between the lobes of the lung
Pleura allows the lungs to move inside the body cavity without friction as friction would cause damage to the lungs and the tissue in the chest wall

Gomez found the masses of three rocks for science project .the first rock had a mess of 19.28 grams, the second rock had a mass

ziro4ka [17]

The combined mass of rock 1 and 2 = 19.28 + 25.3
= 44.58

Difference between rock 3 and combined rocks
= 46.3 - 44.58
= 1.72 grams

therefore, the third rock was 1.72 grams greater than the combined mass of the other two rocks.

Place the steps of the respiration process in the correct order.

noname [10]

During respiration, 3) Air enters the nostrils. 1) Air passes from the trachea to the bronchi. 4) Air diffuses from the alveoli to the blood cells. 2) Oxygen enters the blood cells. 5) Blood transports oxygen to other cells.

<h3>What is respiration?</h3>

During respiration process occurs gas interchange between the body and the environment.

There are two types of respiration,

1) External respiration involves two different stages, inspiration - inhalation- and expiration -exhalation-.

• During inspiration, the diaphragm and intercostal muscles contractions enhance the size of the thoracic box and reduce internal pressure. As a result, air flows in and fills the lungs.

• During expiration, the diaphragm relaxes, and the volume of the thoracic box diminishes, increasing the internal pressure and making the lungs contract, which results in air expulsion.

2) Internal respiration, during which blood and cells interchange oxygen and carbon dioxide.

Steps:

1) External respiration - Inhalation

Air passes from the environment to the lungs through the nose or mouth.

Oxygenated air moves

• From the nose or mouth to the pharynx.

• From the pharynx to the larynx.

• From the larynx to the trachea.

• From the trachea to the bronchia.

• From bronchia to bronchiole.

• Finally, from the bronchiole to alveoli.

Gas interchange with blood occurs in alveoli.

2) Internal respiration - Systemic circulation

The oxygenated blood moves from the lungs to the heart and the rest of the body.

Gases interchange occurs during this step. Cells take oxygen and release carbon dioxide.

Deoxygenated blood moves from tissues to the heart and from the heart to the lungs, releasing carbon dioxide there.

3) External respiration - Exhalation

Carbon dioxide is released by expiration.

Correct order of steps

3) Air enters the nostrils.

1) Air passes from the trachea to the bronchi.

4) Air diffuses from the alveoli to the blood cells.

2) Oxygen enters the blood cells.

5) Blood transports oxygen to other cells.

Which of the following statements is the most likely explanation for plant withering due to leaky membranes in cold temperatures

podryga [215]

Answer:

C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.

Explanation:

Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.

In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.

Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.
