Answer:
Glucose is made of six carbon atoms, six oxygen atoms, and twelve hydrogen atoms. When the plant makes the glucose molecule, it gets the carbon and oxygen atoms it needs from carbon dioxide, which it takes from the air
Answer: b. The use of protein as an energy source is greater for endurance atheletes than those who body build or lift weights.
Explanation:
Proteins are the biomolecules. They are composed of polymers of amino acids. It is required by the body to repair tissues and build muscles, bones, and necessary component of skin, and cartilage.
The body of athletes require more protein than body builder or weight lifters. This is because during athletic practices like running, swimming and others the muscular mass should be strong enough to conduct long continous practice. The muscle mass is build up by proteins. The muscles may experience lack of oxygen during regular practice and may become weak. Thus require more protein so that the strength may remain maintained.
Answer:
(A). Sexual reproduction increases genetic diversity, and asexual reproduction can be more rapid.
Explanation:
Sexual reproduction is a mode of reproduction, which involves formation of new organisms by combination of genetic information from two organisms of different sexes. The major advantage of sexual reproduction is to develop genetic diversity as new organism is produced by mixing up genetic material of both the parents.
On the other hand, asexual reproduction involves formation of new organisms from a single parent having identical genetic makeup as present in parent cell. One of the major advantage of asexual reproduction is to produce high number of offspring in less time as it is more rapid than sexual reproduction.
Thus, the correct answer is option (A).
Work is done on an object only if the force and displacement are in the same direction.
Non-critical thinking appears to be more benifentail to the individual in education.
