Natural selection has to do with organisms being best suited for their environment surviving and reproducing more often.
What is natural selection?It is a process by which living organisms evolve.
The natural selection theory was proposed by Darwin. It states that organisms with traits that enable them to adapt better to the environment survive better and contribute more to the future population.
In the process of reproduction, the adaptive traits are passed to future generations. Thus, the future generation would be made up of individuals with adaptive traits.
Weak individuals without the adaptive traits gradually fade off from the population.

Question 8 options: A) Six molecules of carbon dioxide plus six molecules of water plus light energy converts six molecules of oxygen plus sugar. B) Six molecules of oxygen plus six molecules of water plus light energy converts six molecules of carbon dioxide plus sugar. C) Six molecules of water plus six molecules of hydrogen plus six molecules of oxygen converts light energy plus sugar. D) Six molecules of carbon dioxide plus sugar plus light energy converts six molecules of carbon and six molecules of oxygen.
Answers
Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar, Thus, the correct option is A.
What is photosynthesis?Photosynthesis is the process through which plants use sunlight to create their own nourishment. Through a sequence of reactions, light energy from the sun is turned into chemical energy, which is then stored in the form of food.
In the presence of sunlight, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react to form 1 molecule of glucose sugar. During photosynthesis, 6 molecules of oxygen are formed in addition to glucose.
The following is a balanced chemical reaction for photosynthesis:
Sunlight
6CO2 + 6H2O —---------> C6H12O6 + 6O2.

What's function of ADH
Answers
ADH is the Antidiuretic hormone. This is a brain hormone that induces the kidneys to discharge less water, resulting in less generation of urine.
Arginine vasopressin is another name for ADH. The hypothalamus in the brain produces this hormone, which is then stored in the posterior pituitary gland.Vasopressin is a hormone that promotes vasoconstriction and water reabsorption in the renal tubules of the kidney.The amount of water in the blood is constantly regulated and balanced by ADH.Higher water concentration raises the volume and pressure of the blood. Water metabolism is maintained by osmotic sensors( to sense the osmotic pressure) and baroreceptors(to sense the blood pressure) in conjunction with ADH.ADH deficiency often results in an unusual water metabolism condition called diabetes insipidus. A reduction in either the generation of ADH by the hypothalamus or the release of ADH from the pituitary gland is the major causal factor of diabetes insipidus.Excessive urination( polyuria) is a common symptom of this disease, followed by intense thirst, known as polydipsia.To learn more about the ADH, refer to:-

What is genetic variation in plants??
Answers
Answer:
Individual differences or population differences are referred to as genetic variations.
Explanation:
Individual differences or population differences are referred to as genetic variations. Plant breeders can use genetic variability/diversity to improve cultivars with desired qualities and generate new cultivars with both farmers- and breeder-preferred traits (yield potential, early maturity, good shapes, taste, color, extended shelf life, easy to prepare) (disease and pest resistance). Plant breeders and local farmers have harnessed natural genetic variability to boost their yield. GA plays a crucial part in the alleviation of poverty as the population grows. Plant breeders benefit from population variation because it allows them to explore the source and develop new cultivars. Mutation, hybridization between incompatible kinds or introgression, wide-hybridization, and recombination could all be used to accomplish this. Mutation, natural selection, environmental diversity, genetic drift, migration, and population size all have an impact on genetic variability.
Answer:
Gene variation in plants often occurs as the result of gene flow. Pollen is dispersed from one area to another by the wind or by pollinators over great distances. Examples of genetic variation in animals include albinism, cheetahs with stripes, snakes that fly, animals that play dead, and animals that mimic leaves.
