It must pass from the nucleus to the ribosomes, hope this helped!
<h3><u>Answer;</u></h3>
In metaphase I, the chromosome tetrads align on metaphase plate
while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.
<h3><u>Explanation;</u></h3>
- Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes
.
- Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
- During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
Answer:
a. Heart...
b. pulmonary artery
C. lungs
d. pulmonary vein
e. heart
f. aorta
g. arteries
h. big toe.
Explanation:
First I will go from the heart to the lungs through pulmonary artery in order to purification from carbondioxide and loaded oxygen. After that, I return to the heart through pulmonary vein and the heart pump this blood to the aorta which is a big blood vessel that branched into small arteries that reaches to every cell of the body and through these arteries I reach the big toe of the foot.
Answer: naomi, who is not breathing and whose heart is not beating
A person is considered clinically dead if their blood circulation and breathing is stopped because those two is needed to sustain live. Notice that the diagnosis need both of them, so only one of them is not enough. Helga and John has no problem in breathing and circulation, so they wont be considered clinically dead.
Answer: The father determines the biological sex of a baby
Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.
What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.
