Answer:

Ten times meaning you multiply 40 by 10.

40 × 10 = x

400 = x

igomit [66]

The answer is; Porosity which affects soil texture

The largest particle size is referred to as sand, medium is silt, while the small particles are clay. Soil texture is determined by the ratio of these three in its mixture. Soil with a higher proportion of clay becomes waterlogged easily when it rains. The right kind of soil for farming is loam because it is well drained.

When you compress the heart in this demonstration, why does the water

kifflom [539]

Answer:

D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.

Explanation:

the question is incomplete, but I annex the options and their explanation

When you compress the heart in this demo, why does the water leave the artery?

A It's like squeezing a sponge

B The arterial valve draws water from the ventricle.

C The atrioventricular valve has parachute-shaped fins to prevent water from escaping from the top.

D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.

the atrioventricular valve during the contraction process closes at the top, thus avoiding the leakage of the liquid and leaving the artery that opens due to the force exerted by the volume and force of the ventricle.

nutrition student who is learning that a balanced diet involves consuming diverse foods that have a variety of vitamins in them

vesna_86 [32]

Answer:

Answered below.

Explanation:

Vitamins are one of the food nutrients required for a balanced diet. This is because vitamins play a vital role in the functionality and the structural development of our body systems. Vitamins are sometimes referred to as micronutrients because they are needed in smaller amounts by the body.

Vitamins are classified into essential and non-essential vitamins. The non-essential vitamins are readily produced by the body and do not require taking them from external sources while the essential vitamins must be taken in as the body does not either produce them, or doesn't produce them to the amounts it actually need.

The essential vitamins include;

Vitamins A, D, E, K, C and the B vitamins which include vitamins B1, B2, B3, B5, B6, B7, B9 and B12.

These vitamins are further divided into fat-soluble (ADEK) and water-soluble(B vitamins and C)

It is advisable to take at least the recommended dietary allowance of these vitamins in our foods, everyday as they are not synthesized in the body to required amounts. These vitamins are needed for the many metabolic processes occurring in the body and a deficiency of them lead to various diseases examples being;

Scurvy from vitamin C deficiency.

Anemia from folate deficiency.

Night blindness from vitamin A deficiency.

Muscle weakness and fatigue from vitamin D deficiency and many more.

does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy! i need a claim n ev

gladu [14]

Answer:

Explanation:

This question is a practical question and would require some sort of experiment. However, let's define what rate of reaction means. The rate of a chemical reaction (in this case fermentation) can be described as the speed at which the reaction occurs; meaning the speed at which product is formed per unit time.

The "claim" in the attachment in the question can be referred to as hypothesis since this question is an experiment. The null hypothesis here will be "the rate of alcoholic fermentation is not affected by the type of sugar used as an energy source".

The "evidence" from the attachment will be result of the experiment conducted which cannot be provided here.

However, the conclusion of this experiment (which also answers the main question; does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy?) should show that the rate of alcoholic fermentation should differ based on the type of sugar used. This is because different enzymes are responsible for the conversion of this disaccharide to the glucose monosaccharide which is what finally undergoes alcoholic fermentation. For example sucrose is broken down into glucose and fructose by sucrase while lactose is broken down into glucose and galactose by the enzyme lactase.

Note that the reaction rate from glucose to produce CO₂ (a product of fermentation) will be the same (regardless of source) but the reaction time from the disaccharide to glucose will be different because of the difference in enzyme and can also be determined by comparing the time to produce the CO₂ by the sugars and the time to produce same amount of CO₂ when given water in the experiment .
