1. The lining up of chromosomes by the spindle fibers takes place at metaphase II phase. It is the second stage of meiosis II, the spindle draws the chromosomes towards the metaphase plate.
2. The formation of the nuclear envelope around each set of DNA takes place in telophase II. Along with the formation of the nuclear envelope, the process of cytokinesis also takes place in telophase II, producing four daughter cells, each comprising a haploid set of chromosomes.
3. The sister chromatids are pulled apart in anaphase II stage. In this phase, the sister chromatids are migrated towards the opposite poles of the cell with the help of protein fibers.
4. The centromeres are moved towards the poles of the cell at prophase II stage.
Answer:
The correct answer is - leads.
Explanation:
In ECG or electrocardiogram, a test that is used to measure the electric activity of the heart of an individual, each electric impulse cause a electric wave to travel through the heart and cause the heart pump to pump blood.
There are electrodes that received the electric impulse in this machines, electrodes have self adhesive pads and attached with various leads mostly 12, that carries the impulses in the combinations that are recorded on the ECG.
Thus, the correct answer is - leads.
Answer:
Velocity
Explanation:
Given the change in positive (direction) over time we are given the velocity formula.
V = Change in direction/Change in time
Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.
The probability of the female child of Charles and Marie suffering from hemophilia is 50% or 0.5.
<h3>What is the probability of hemophilia?</h3>
Hemophilia is a disease that is linked to the X-chromosome.
The probability of having female who suffers from hemophilia depends on the genotype of the parents.
Assuming that the genotype of the parents are as follows:
Father: XcY --> hemophilic
Mother: XXc --> carrier
A cross between the parents will produce two female offspring with genotypes, XcXc and XXc.
Therefore, the probability of the female child of Charles and Marie suffering from hemophilia is 50% or 0.5.
