The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.
<h3><u>Explanation</u>:</h3>
Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.
This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.
Genetic drift happens when well-adapted organisms survive and reproduce more often than poorly-adapted organisms. <span>The statement that best sums up evolution is the change in a population through genetic variation over time. Natural selection may be through (1) differential reproduction, that is, not all organisms are able to reproduce to their fullest capacity because nature cannot simply sustain it and (2) acquire genes, that is heredity.</span>
Answer:
- The six essential nutrients are vitamins, minerals, protein, fats, water, and carbohydrates.
-The digestive system converts the foods we eat into their simplest forms, like glucose, amino acids or fatty acids.
- The function of the excretory system to remove wastes from the body.
-The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.
-The excretory system works with the endocrine system to help maintain homeostasis. Chemical messengers called hormones signal the kidneys to filter more or less water or salt, depending on the levels of water and salt in the body.
