I think the correct answer would be D. The specialized structure that helps a vascular plant to soak up water after a rainfall in a desert would be the extensive shallow root system with root hairs. An example of this would be the cactus. It has a root system that is very different from any plant that is not found in the desert. The roots are found just exactly below the surface. It is ready anytime to suck up water from rain or snowfall and transport it to the stem of the plant. Also, after a rain, the cactus would grow tiny roots in its body to aid in the absorption of water more quickly.
Answer: So food must be broken down into smaller molecules before it can be absorbed through the blood and transported to cells throughout the body.
Explanation:
Digestion in humans is the process by which food and drink are broken down into smaller parts so that the body can use them as a source of energy to form and maintain tissues. It starts in the mouth, when we chew and eat, that is called mechanical digestion. And it ends in the small intestine, that's called chemical digestion. Although the chemical process varies depending on the kind of food.
<u>So food must be broken down into smaller molecules before it can be absorbed through the blood and transported to cells throughout the body.</u> Then the polymers (large molecules such as carbohydrates, proteins or lipids) are degraded into the simpler components called monomers (monosaccharides, amino acids, glycerol and fatty acids). These monomers are the ones that the body can absorb for use, it cannot do so with large, complex molecules.
Answer:
As farming became more productive, more people were able to : Engage in manufacturing. Rather then rely on manual labor, machine-based labor will reduce overall cost and will lead to big increase in profit
