False.
In a dihybrid cross, the expected ratio of genotypes is 1:2:1:2:4:2:1:2:1.
In this example the ratio is 1:2:2:4:1:2:1:1:1. So, this ratio is false. It is expected 1<span>YYRR : 2YYRr : 1Yyrr : 2YyRr : 4YYrr : 2YyRR : 1yyRR : 2yyRr : 1yyrr.</span>
I dont know what <span> ketogenic or glucogenic is.</span>
This question is incomplete. Here´s the complete question.
A 70-year-old client with a diagnosis of left-sided stroke is admitted to the facility. To prevent the development of disuse osteoporosis, which objective is most appropriate?
a) Promoting range-of-motion (ROM) exercises
b) Promoting weight-bearing exercises
c) Maintaining protein levels
d) Maintaining vitamin levels
Answer: b) Promoting weight-bearing exercises
Explanation:
The bone is a living tissue that becomes stronger with exercise. Weightlessness and immobility can lead to bone loss.
Weight-bearing exercises are those that force us to work with gravity, like walking, hiking, jogging, climbing stairs, playing tennis, and dancing. They can help prevent disuse osteoporosis.
On the other hand, swimming and bicycling would be examples of non-weight-bearing exercises.
Answer:
The water cycle
Explanation:
<em>Possible answers include that water is stored as ice and snow on the ground during the water cycle. Water is also stored in clouds until precipitation occurs, which transfers water from the atmosphere to the ground. On the Earth's surface, water can be stored in liquid form in streams, rivers, lakes, and oceans.</em>
Answer:
Two gametes end up with 30 chromosomes, one gamete will have 31 and one will have 29.
Explanation:
During meiosis, a single diploid cell divides into four haploid cells with half the chromosome number than the parent cell.
During meiosis I, homologous chromosomes separate and the chromosome number in the two daughter cells goes down by half. During meiosis II, the "sister" chromatids separate, and the chromosome number in the respective daughter cells remains the same.
Non-disjunction of a single dyad in meiosis II causes that one of the daughter cells will have an extra chromosome, and another will be lacking one. The two other gametes will be normal.
I drew a simple example of what would happen during meiosis of a 2n=4 cell if there was non-disjunction in a single dyad during meiosis II.
