Human beings are responsible for the loss of forest. Why?​
Blababa [14]

Beause we cut down a lot of trees. Often, so many, that the health of a forest is irreparably damaged. A forest is not just a bunch of trees. It is a whole ecosystem, in which the trees anchor the growth of many other plant and animal species, hold the ground together to prevent erosion, and produce a lot of oxygen to support animal life. If you harvest too many of the trees, the local ecosystem stops being a forest and starts turning into something else

A strawberry plant is an example of a plant that can reproduce through the process of vegetative reproduction. Are the offspring
alexandr402 [8]
The offspring will be genetically identical to the parent because vegetative reproduction is a form of asexual reproduction. Therefore, there is only one parent and the offspring is identical to the parent.

Which of the following terms describes the movement of water from the surface to the atmosphere?
lukranit [14]

Answer:

The answer is evaporation.

Explanation:

Runoff is not right because runoff is water that hits the surface of the earth, then runs down into natural bodies of water. It is not condensation either. That is because condensation is when cool water vapor comes into contact with humid, warm air causes water droplets to appear on the surface of what is containing the cool water vapor. Finally, precipitation is when water comes down from the atmosphere to the surface of the earth, therefore this is incorrect. Evaporation however is when water from the surface of the earth turns into water vapor and goes into the atmosphere. Therefore it is the right answer.

Lactose when digested, it is hydrolyzed by lactase into its monomers, which are then absorbed by blood. Following are test resul
kap26 [50]

Answer: Based on the information, the person DOES NOT have lactose intolerance because glucose levels significantly increases in normal individuals after a lactose rich meal.

Explanation:

Lactose is a disaccharide carbohydrate which when taken (found mostly in diary products) is hydrolyzed by lactase into its monomers, which are then absorbed into the blood. The hydrolysis of lactose gives glucose and galactose which is carried out by the digestive enzyme lactase. Deficiency of the lactase enzyme gives rise to a disorder known as LACTOSE INTOLERANCE.

The diagnosis of lactose intolerance or lactase deficiency can be confirmed by measuring the plasma glucose concentrations, as in glucose tolerance test, after giving an oral load of lactose rich solution. If the disaccharide (lactose) cannot be hydrolysed, the constituent monosaccharides cannot be absorbed and the concentrations of plasma glucose rise VERY little.

But the fasting blood glucose done after 2 hours of drinking a lactose rich solution showed a typical rise in blood glucose levels which were 80, 90, 100, 110 and 120 mg/ dL tested for every 30 minutes. This indicates that the individual does not have lactose intolerance because the glucose gotten from hydrolysed lactose was absorbed and cause a significant rise in blood levels.
