Reproduction is the biological process by which new organisms known as the offsprings are produced by their parents. It is of two types: Sexual reproduction and Asexual reproduction. The difference between the two types lies in the number of parents required for both. In Sexual reproduction, two parents are required to give rise to the offspring. In asexual reproduction, a single parent can give rise to the offspring. Asexual reproduction is commonly seen in plants but is less common in the animal kingdom.
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
CONCLUSION:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population.

This question can't be answered as written. In order for me to answer this question you will need to provide the information for the cross. What are the phenotypes of the parent plants in the cross?
Answer:
The correct order of these elements from least to most complex is atom → molecule → carbohydrates → monosaccharide → disaccharide → polysaccharides.
Explanation:
Carbohydrates are organic molecules formed by carbon, hydrogen and oxygen, whose complexity is received in the amount of monomers they possess.
According to their level of organization, carbohydrates are constituted by:
- <u>Atomic level</u>: atoms of carbon, hydrogen and oxygen.
- <u>Molecular level</u>: these are the carbohydrate molecules that can be formed, from the simplest to the most complex:
- <em>Monosaccharides</em><em>: or simple sugars, such as glucose.</em>
- <em>Disaccharides</em><em>: are formed by two monomers. An example of this is sucrose, formed by glucose and fructose.</em>
- <em>Polysaccharides</em><em>: formed by chains of more than 2 carbohydrates, such as starch.</em>
The term carbohydrate groups all possible forms of these molecules, from the simplest to the most organized molecular.
The solutions would be a, b, e, f.
