Answer:
False
Explanation:
Indoor pollution is rather more dangerous and is caused by harmful chemicals. Due to restricted area, the density of the pollutants is higher indoor, and thus, they are build up more inside.
Answer:
Global warming poses a series of challenges to agriculture, such as:
Changing rain patterns, where there are long periods of heavy rain followed by longer dry periods. That change can occur even within small regions.
The same to temperature patterns, drying up water reservoirs and actually burning up crops that, at that time, need a more humid environment.
Those changes can also trigger greater numbers of floods, droughts, and other effects on crops that livestock depend upon. That change in crops, in turn, may bring new insects that otherwise would not thrive there, decimating entire lands that were naturally protected from, those pests before.
Those are just some of the examples of climate change effects on agriculture and, therefore, to men.
Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.
Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.
To find: The total population size of the frogs in the pond.
Method: Using unitary method of proportions
Solution:
Let p be the density of the frogs present per square meter.
Let A denote the total area of the pond.
∴ p = 12 frogs/m² and A = 370 m²
The total number of frogs in the pond is given by,
Therefore, there are 4440 frogs in the pond.
Answer:
The three sections of the small intestine are the duodenum,
Explanation:
The duodenum
It receives chyme from the stomachs
Its intestinal cells enzymes such as secrete amylase, sucrase, and lipase enzymes that break down fats and sugars.
The jejunum
It is covered in villi and microvilli giving the name THE PRINCIPAL SITE of digestion.
the ileum.
Aid absorption e.g. amino acids, lipids, fat-soluble vitamins, and vitamin B12.
