There are 4 outer atoms and lone pairs that are present in a molecule with a see-saw shape. It was called "seesaw" comes from the observation that it looks like a playground seesaw. It is very common that four bonds to a central atom result in tetrahedral or, less commonly, square planar geometry.
If Alpa wants to change 0.54 kilometers into a smaller metric unit, she will be required to multiply.
<h3>What is a Metric unit?</h3>
A Metric unit may be defined as a technique of measurement in which the basic units are the meter, the second, and the kilogram. These units are interchanged with one another by using several formulas of conversion.
The complete question is as follows:
Alpha wants to change 0.54 kilometers into a smaller metric unit. She will have to:
- multiply
- divide
- add
- subtract
Therefore, If Alpa wants to change 0.54 kilometers into a smaller metric unit, she will be required to multiply.
For example, In case, if she wants to convert 0.54 into meters, then she has to multiply it by 1000, that is, 0.54 * 1000 = 540 meters.

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.
