Answer:
1/4
Explanation:
1-Mother:
The probability to pass the disorder to her progeny is: 1 x 1/2 = 1/2
Father:
2-The probability to pass the disorder to his progeny is: 1 x 1/2 = 1/2
Therefore, the probability to have the disorder is equal to the product of both independent events, i.e., 1/2 x 1/2 = 1/4 or 25%
The correct answer is A) Generates new combinations of alleles upon which selection can act.
Explanation:
In biology, there are two main kinds of reproduction: sexual and asexual. Asexual reproduction occurs when there is only a parent involve and this divides, splits or similar to form new cells or organisms that are genetically identical to the parent. On the other hand, in sexual reproduction, there are two parents involved, usually from opposite sexes and the alleles of both are combined in the offspring. The main advantage or benefit of sexual reproduction is that it involves the combination of alleles which means genetic variation, this makes the population able to adapt and evolve as selection acts and also makes a population less vulnerable to diseases. Thus, a benefit of sexual reproduction is that "Generates new combinations of alleles upon which selection can act".
The movement of nutrients into the vascular stele requires energy, unlike the movement of water that does not require energy. This energy is provided by the phloem. Sugars are produced in the leafs, as part of the photosynthesis process, so whenever a new root is growing, or a fruit needs to grow, the phloem gets in action. With the help of the water the sugars get in the phloem, which can most simply be seen as an elevator inside the plant, that is moving nutrients up and down, on the places in which they are most needed.
