Answer:
There are Five main compounds but our body need carbohydrate and protein more.
Explanation:
There are five major organic compounds that our body needs for normal metabolic processes. These are- Carbohydrates, lipids, proteins, nucleic acids and high energy compounds. organic compounds are involved in almost all biochemical activities that is related to metabolism. The organic compounds always contain carbon. Carbs act as the source of energy to the body. They converted to glucose, which used in cellular respiration. Lipids act as fatty acids. Proteins have a structural function like keratin in skin and hair. Nucleic acids are large organic compounds that store and process information at the molecular level inside the body cells. High energy compounds like ATP serves as a source of cellular energy.
Answer:
Desertification is the destruction of the biological potential of the land and it is generally viewed as an advanced stage of land degradation. human activities also cause the process such as poor irrigation practices, deforestation, the expansion and intensive use of agricultural lands, and overgrazing.
Such human activities put enormous pressure on the land by altering its soil chemistry and hydrology. Modern agriculture causing a negative impact on the soil and land by overexploiting the biological and chemical potential of the land.
The best answer is B.
The endosymbiotic theory states that mitochondria and chloroplasts have striking similarities to bacterial cells:
1. they have their own DNA, which is separate from the DNA found in the nucleus of the cell.
2. Both organelles use their DNA for to produce many proteins and enzymes required for function.
3. They are both surrounded by a double membrane.
4. They reproduce just the way bacteria do, replicating their own DNA and directing their own division.
Answer:
The activation energy required for an exploding firework is less than the activation energy required for a burning candle.
Explanation:
I did this in class. The height of the activation is lower for the firework than the burning candle.
The difference between a multicellular organism and a colonial organism is that individual one-celled organisms from a colony can, if separated, survive on their own. so yes colonial organisms can live on their own.
