Answer:
B
Explanation:
They're adding the increase to the already existing populaton. There were already 49, but 11-8 = 3, so there are now 52 meerkats.
Answer:
1. The school board wants to clear the forest surrounding the local high school to build more fields for high school sports. Following environmental factors need to be investigated before clearing the land:
1. Destruction of natural ecosystem: As forest will be cut the land will be barren. There will be loss , extinction and migration of faunal species. So, the normal balance of ecosystem will b disturbed.
2. Chances of climatic fluctuations: As, forest will be cleared, the water, carbon and oxygen cycle in the atmosphere will be disturbed. The region may not acquire adequate rainfall, temperature of the area will change drastically.
3. Soil erosion: As, forest will be cleared the soil will not be hold up and the loose soil gets wiped out from the location by water or air.The cutting of trees can cause flooding from nearby water body.
2. Two ways to reduce air pollution and slow climatic change are:
1. Control use of fossil fuels: Fossil fuels like coal, petrol, kerosene are used in automobiles, industries and house hold activities. These fossil fuels are organic in nature and adds up carbon dioxide, carbon monoxide, nitrogen dioxide gases in air and raises the atmospheric temperature and are responsible for air pollution. Therefore, the use of fossil fuel should be in control manner.
2. Planting more number of trees: The trees are responsible for fixing atmospheric carbon from air for photosynthesis. So, they can decrease the amount of atmospheric carbon abundantly present in forms of carbon dioxide and carbon monoxide, which are chief air pollutants. These carbon products are responsible for raising temperature so planting of trees can prevent raise of temperature.
Answer:
This question lacks options, options are:
A) histamine
B) gastrin
C) secretin
D) ACh
The correct answer is C.
Hormones or paracrines that inhibit gastric secretion include <u>secretin
</u>.
Explanation:
Hormones pass into the blood that waters the digestive system, go to the heart, circulate through the arteries and return to the digestive system, where they stimulate the production of digestive juices. The hormones that control digestion are gastrin, secretin and cholecystokinin. Secretin is stimulated by intestinal acid at the duodenal level. Its effect inhibits gastric acid secretion, prostaglandin secretion and via somatostatin release. It decreases gastric emptying and stimulates bile and pancreatic bicarbonate secretion.
Answer:
Glucose
Explanation:
Photosynthesis requires sunlight, carbon dioxide and water to produce glucose. This simple sugar is a carbohydrate that combines with other sugars to form the plant's structure and stores energy for future use. Hope it's useful!
The cell is the smallest level of organization and is composed of chemicals and atoms. These chemicals regulate the structure and functioning. Thus, the statement is true.
<h3>What is a cell?</h3>
A cell has been defined as the basic unit of the organization of organisms that have been known to be composed of chemicals, atoms, and molecules. They are bonded together to perform various functions.
The chemicals and elements involved are the fundamentals that provide the structural support and functions of the cell like the carbohydrates and lipids provides shape to the cell.
Therefore, the statement is true.

Your question is incomplete, but most probably your full question was, that cells are composed of chemicals, and both the structure and function of cells are regulated by basic chemistry principles. (True/false).
