8. which of the following statements is true? A. Glacial erosion forms wide, U-shaped valleys B. Mudflows are the least dangerous type of sediment flow C. mass wasting happens when sediment is carried from a low elevation to a higher one D. in saltation, acids and salt in ocean water dissolve rock minerals

Answers

The correct answer is - A. Glacial erosion forms wide, U-shaped valleys.

The glaciers are essentially large masses of ice, formed either by large mas of snow or a frozen river. Because the ice is expanding, but also the glaciers appear at higher places and slowly move towards lower parts, they contribute to a lot of erosion. The size and their weight, plus their movement and the pressure they make, the glaciers manage to erode lot of material, and by doing so, they reshape the landscape in accordance to their form, which is an elongated, river like, U-shape. Once they are melted, the glaciers leave behind them long and narrow U-shaped valleys, some of which remain as a valleys, while others are filled with sea water and formed the fjords.

All living things need energy; it is a requirement for life. In a typical cell, ATP, the high energy molecule, is produced in the __________ in the presence of of a sugar, glucose, and ______________.

Answers

1. Mitochondria
2. Oxygen

In the presence of oxygen, one glucose molecule has the energy to make up to 38 ATP. The ATP production is determined by the following steps, (-2 ATP) glycolysis preparatory phase, (7-9 ATP) glycolysis pay-off phase, (5 ATP) oxidative decarboxylation of pyruvate and (20 ATP) Krebs cycle. One glucose which has 38 ATP hence was the summation of all the process mentioned that took place. All these process take place under the cellular function of cellular respiration.

C) mitochondria; oxygen.
