The core, or middle, of the Sun is the hottest part. Hot gasses bubble up from the core to the surface of the Sun. When the gasses burn, heat and light are produced.
Chlorophylls (green pigments of the plant) absorb light most strongly in the blue portion of the electromagnetic spectrum, but also the red portion. On the other hand, chlorophylls are a poor absorber of green portions of the spectrum, which it reflects and thus produce the green color of chlorophyll-containing tissues (that’s how plants are green).
A simple version of everything is Red and Blue Light.
C) proteins
D) nucleic acids
E) lipids, carbohydrates, proteins, and nucleic acids all consist of only macromolecular polymers
Answer:
(Correct option is B) Carbohydrates.
Explanation:
Biological molecules are known as the molecules which are found in the organisms, and play some important roles like development, cell division, and morphogenesis. They are necessary for the life.
Carbohydrates are known as the classes of biological molecules which consist of small molecules, and macromolecular polymers both. Carbohydrate are divided into three subtypes of essential macromolecules:
1) Monosaccharides: Fructose, galactose, and glucose are isomers of monosaccharide.
2) Disaccharides: Sucrose is the isomer of disaccharide.
3) Polysaccharides: Starch, cellulose, and glycogen are example of polysaccharide.
Glucose, and sucrose are known as the small molecules of carbohydrates, and other molecules of carbohydrate such as polysaccharides are known as macromolecular polymers.
Answer: True
Humans have impacted the rainforests through mining, agriculture and construction as rainforests are mainly occupied with large forests trees and vegetation. Human clear cut the forests to make the land available for the purpose of mining to derive economically valuable minerals from earth, construction of house and for agriculture. This has resulted in the extinction of large number of floral and faunal species from earth. It has decreased the percentage of forest cover on earth.
According to the question, it is true that Humans have impacted the rainforests through mining, agriculture, and construction.
How human impacted the rainforests through mining
Gemstones and Precious metals such as gold, copper, diamond are important resources that can be found in the rainforests across the world. Extracting these resources is harmful activities that contribute lot of damages to the rainforests ecosystem. It causes problem for the people that live close to the rainforests. Chemical pollution and deforestation from mining can have a great adverse effect on the rainforests environment. It also affects downstream aquatic habit.
How human impacted the rainforests through Agriculture
In the rainforests, large areas are cleared for pastoral farming because the demand of meat globally has increased the opening of cattle farms in the rainforests and this also cause deforestation which has adverse effect on the rainforests. Arable farming also contribute to the loss of tropical rainforests as many farmers are clearing the land to grow crops such as soya beans.
How human impacted the rainforests through Constructions
Road building has different of direct impacts on the rainforests. In most wet tropical rainforest, the cut and fill operation related with road construction can prevent easy flow of streams, increase flooding in the forest and can drastically increases erosion in rainforests. Construction of roads in the rainforest can discharge nutrients and chemical pollutant into water ways and create avenue of invasion for disturbing exotic species.
