Each chromosome contains one molecule.
A food web has many different links; It links off into different animals. Where as a food chains just a line of single animals that eat those animals for example: like hawks eat bunnies and bunnies eat grass and grass is the producer.
hope this helps u out...good luck
Answer:
Sexual reproduction:
Pros: leads to greater genetic variation.
Cons: requires more time and energy.
Asexual reproduction:
Pros: Does not require finding a mate.
Cons: Produce less genetic variation.
Explanation:
Sexual reproduction is a type of reproduction in higher organisms, in which new individuals are formed by combining genetic information from two different types (sexes) of individuals.
Advantage: Sexual reproduction leads to higher genetic variation due to recombination between genetic material of female and male gamete during meiosis.
Disadvantage: Sexual reproduction is a time and energy consuming process as it needs interaction between mates and organisms which are produced sexually require more time for development.
Asexual reproduction involves formation of new organisms from a single parent organism without gamete fusion.
Advantage: Asexual reproduction requires less time and energy as it does not require finding a mate.
Disadvantage: Asexual reproduction produces less genetic variations as it involves only parent organisms (no mixing of genetic information) and the only source of variations are random mutations.
Photosynthesis is a process plants and other organisms use to create energy. The energy from sunlight, glucose, water, oxygen, and carbon dioxide are used by the plant to photosynthesize. These chemicals work together within the plant and produce energy. Oxygen is a product of photosynthesis that benefits humans and animals. Photosynthesis is essential for most plants to live.
Obsolete body of thought on the ordinary formation of living organisms without descent from similar organisms. Typically, the idea was that certain forms such as fleas could arise from inanimate matter such as dust, or that maggots could arise from dead flesh.
