Goryan [66]3 years ago

<span>Lactase is a digestive enzyme that catalyzes the break down of lactose, a sugar found in milk. Lactase functions best within limited ranges of both temperature and pH in its given environment, making it dependent on both factors for it to perform this essential reaction. If lactase is rendered nonfunctional because of temperature or pH extremes, the breakdown of lactose stops. When this breakdown ceases in the human body due to insufficient or ineffective lactase, the result is lactose intolerance.</span>

1 Explain why animals depend on plants to keep them alive.
Gnoma [55]

1. Animals depend on plants to keep them alive is Plants are producers  they take energy from the sun, nutrients from the earth, and water to grow and have their flowers, seeds, and berries.

They also release oxygen, which all animals, including humans, need to stay. Animals are consumers and they all depend on plants for survival.

2. carbon dioxide and water reach the chloroplasts in leaves is Basically the roots consume the water and transports it up the xylem, which gets it to the leaves. Carbon dioxide contacts the chloroplasts in the leaves via a stomata

3. Two pieces of evidence that show that plants cannot make their own food without light. When plants lack light, they don't deliver chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be advancing toward the source of light.

  • The photosynthesis is the only method for synthesizing food. It is commonly believed that about 717.6Kcal energy is required to prepare just 10g of glucose. No energy input no metabolism and therefore no food.

<h3>How are leaves tested for starch?</h3>

The existence of starch in leaves can be tested by the Iodine test. When we remove chlorophyll from the leaf by cooking it in alcohol and then placing two drops of iodine solution, it is a color change to blue indicates the existence of starch.
