Question 10: True Question 11: Competition and Variation
Explanation:
Natural Selection is when the animal with the best survival rates gets the right to mate. Every species wants to survive and by letting the animals with the best traits reproduce, it ensures their survival. This, of course, happens naturally.
Competition is to show whose fit and whose not and variation increases the chance of their survival. For example, if a whole species was exactly the same if one died of a disease then all of them would, because they would have the same immune system. But if there is variation, one might be vulnerable to the disease but the other might have protection from it. Meaning it could pass those genes to offspring because it was fit.
Hope this helped :)
Answer:
The correct answer is plants have two parts life cycle spending one part of their life in diploid phase and the other part in the haploid phase,human spending their lives in diploid phase and produces gamets that are haploid.
Explanation:
There are two stages in the life cycle of plant one is gametophyte stage which is haploid and the other is sporophyte stage that is diploid.
but in case of humans the overall life cycle proceed in diploid phase and produces gamets that are haploid.
In case of human male produces haploid gamet known as sperm and the female produces haploid gamet know as ovum. The sperm and ovum fuses to form diploid zygote,
