Asexual Reproduction occurs when there is only one parent that gives rise to an offspring which has the identical genetic makeup
of the parent. It occurs in most single celled organisms such as bacteria and some multicellular organisms such as fungi and some plants. Some advantages of asexual reproduction are it is fast and efficient. It does not require a male and a female. Organisms can reproduce quickly! A disadvantage is that there is no genetic diversity and it can only be done by simple organisms. Sexual Reproduction involves the combining of genetic information from two parents to produce a new organism that is a combination of both parents. It occurs in most complex organisms. Some advantages to sexual reproduction are that it creates genetic diversity. It allows for evolution of the species. A disadvantage is that it requires two organisms to reproduce, a male and a female. It also requires more energy than asexual reproduction.
Using the table below, list at least two advantages and disadvantages of Asexual and Sexual Reproduction.
asexual reproduction sexual reproduction:
advantages: advantages:
Sexual reproduction: Advantages: A species can evolve or adapt to changing environments, genetic diversity Disadvantages: Time and energy needed to find a mate, requires both male and female gametes, one individual cannot reproduce
Asexual reproduction: Advantages: Only one individual is needed to reproduce, doesn’t require time or energy to find a mate, can reproduce rapidly in good conditions Disadvantages: No genetic variation, all of the offspring have the same weaknesses, can’t adapt or evolve
Ice ages have occurred in the earth history and do occur more or less regularly in a cycle. It is believed that ice ages are as a result of small changes in the earth's orbit and also dependent on the solar cycles. The temperatures on the earth reduce causing the ice sheets in the poles to extend to the subtropics.
The correct answer is D. Heat is transferred by radiation in Step 1 and by conduction in Step 2 radiation- the process of heat moving through the air conduction- the process of heat moving from one object to another object by physical contact
Coal is a fossil fuel. It comes from the remains of plants that died about 100 to 400 million years ago. Coal is a non-renewable energy source because it takes millions of years to form
