Q: What natural destructive element cuts away at rock forming river valleys? Read this paragraph and choose the correct option from the provided answers: Lactic acid fermentation converts the 3-carbon pyruvate to the 3-carbon lactic acid (C 3 H 6 O 3 ) (see Figure below ) and regenerates NAD + in the process, allowing glycolysis to continue to make ATP in low-oxygen conditions. Since there is a limited supply of NAD + available in any given cell, this electron acceptor must be regenerated to allow ATP production to continue. To achieve this, NADH donates its extra electrons to the pyruvate molecules, regenerating NAD + . Lactic acid is formed by the reduction of pyruvate. Choices: - sediment - lava - air - water A:
water

Q: What prevents soil erosion on a hillside that is being farmed? Read this paragraph and choose the correct option from the provided answers: Although the hillside is interesting, that's not why this was done. Terracing prevents soil erosion on a hillside that is being farmed. Many techniques can be utilized to reduce soil erosion. Choices: - slash-and-burn - irrigation - no-till farming - terracing A:
(Answer)
terracing

Ques: Q: What are xylem and phloem responsible for transporting to the cells of leaves? Read this paragraph and choose the correct option from the provided answers: Veins are made primarily of xylem and phloem. They transport water and minerals to the cells of leaves and carry away dissolved sugar. Choices: - air and dirt - water and blood - light and gas - water and minerals A:
Ans: water and minerals

(Q).
Q: What is the term for coiled structures made of dna and proteins? Read this paragraph and choose the correct option from the provided answers: Chromosomes are coiled structures made of DNA and proteins. Chromosomes are the form of the genetic material of a cell during cell division. During other phases of the cell cycle, DNA is not coiled into chromosomes. Instead, it exists as a grainy material called chromatin . Choices: - neutrons - nodes - platelets - chromosomes A:
(A).
chromosomes

Ques:Q: Why does neptune's appearance change? Read this paragraph and choose the correct option from the provided answers: Neptune's appearance changes due to its turbulent atmosphere. Winds are stronger than on any other planet in the solar system. Wind speeds can reach 1,100 km/h (700 mph). This is close to the speed of sound! The rapid winds surprised astronomers. This is because Neptune receives little energy from the Sun to power weather systems. It is not surprising that Neptune is one of the coldest places in the solar system. Temperatures at the top of the clouds are about 218C (360F). Choices: - the seasons - the changing orbit - the speed of rotation - turbulent atmosphere A:

Ans:turbulent atmosphere

Question: Q: What is the primary force driving fluid transport between the capillaries and tissues? Read this paragraph and choose the correct option from the provided answers: Hydrostatic Pressure The primary force driving fluid transport between the capillaries and tissues is hydrostatic pressure, which can be defined as the pressure of any fluid enclosed in a space. Blood hydrostatic pressure is the force exerted by the blood confined within blood vessels or heart chambers. Even more specifically, the pressure exerted by blood against the wall of a capillary is called capillary hydrostatic pressure (CHP), and is the same as capillary blood pressure. CHP is the force that drives fluid out of capillaries and into the tissues. As fluid exits a capillary and moves into tissues, the hydrostatic pressure in the interstitial fluid correspondingly rises. This opposing hydrostatic pressure is called the interstitial fluid hydrostatic pressure (IFHP). Generally, the CHP originating from the arterial pathways is considerably higher than the IFHP, because lymphatic vessels are continually absorbing excess fluid from the tissues. Thus, fluid generally moves out of the capillary and into the interstitial fluid. This process is called filtration. Choices: - temperature pressure - constructs pressure - isolate pressure - hydrostatic pressure A:
Answer:
hydrostatic pressure
