MissTica2 years ago
4 0

atom is made up of 3 particles protons(positive charge), neutrons(neutral in charge), electrons (negative in charge). proton and neutrons are found in core of atom and form atomic weight of the molecule and electrons moves in shells around core.

example - sodium have 11 protons, 12 neutrons and 11 electrons.

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.

The following is a list of vessels. Place them in the order that blood would go through entering the systemic circulation. 1. Le
Alexus [3.1K]

Answer:

E. 3, 6, 7, 4, 5, 8, 1, 2

Explanation:

Systemic circulation is the circulatory pathway which is involved in the transport of the oxygenated blood to the body when pumped by the heart through arteries, capillaries and then back to the heart.

In the given question, the order of vessels in the systemic circulation has been asked which begins with the entry of the deoxygenated blood to the heart.

1. The deoxygenated blood enters the blood from vena cava to the right ventricle.

2. From the right ventricle, the blood enters the right atrium which pumps the de-oxygenated blood to the lungs through an artery called the pulmonary artery.

3. In the lungs, the blood becomes oxygen rich and is returned to the left atrium through the pulmonary vein.

4. The blood then enters the left atrium which is then pumped to the body through the main artery called the aorta.

This completes the systemic circulation and thus, Option-E is correct.
