<h2>Answer:</h2>

<u> A bar magnet orient itself to the </u><u>opposite polarity</u><u> of planet’s magnetic field  </u>

<h2>Explanation:</h2>

As we know that the earth acts like a very big but a weak magnet and that's why compasses point north. If we take a bar magnet and let it hang freely by the help of a string then we will see that the magnet's north pole would point to the Earth's south pole. and the magnet's south pole would point to the Earth's north pole and that is because we know that opposite poles attract each other.

Why does a hormone only act on specific cell types in an organism and not others?

Hormones are chemical signals that are secreted into the circulatory system acting as regulators within the body, and even though they can reach any part on the body, <em>only certain types of cells are equipped to respond, these cells are known as target cells, when the hormone reaches a cell with an adequate receptors it triggers a signal transduction and then a response.</em>

Therefore the correct answer is c.

Dmitry_Shevchenko [17]

Answer: The correct answer to the fill in the blank is Mitosis.

Mitosis is a type of cell division that results in the formation of two daughter cells having the same number of chromosomes as compared to their parent cell. Thus, by producing more number of identical cells, mitosis helps in the growth and repair of tissues.

Thus, after removal of cyst from the liver of Bob, the cells would grow and repair the area through mitosis.

Please answer 5&amp;6. Thank you.
erastovalidia [21]

Answer:

5. The correct answer would be an option A. ova

Note: I assume that all the samples are of human origin.

DNA (deoxyribonucleic acid) content of somatic cells of humans consists of 46 chromosomes or 23 pairs of chromosomes. Gametes (sperm or ova) are haploid cells produced by the process of meiosis and contain half the number of chromosomes found in parent cell. Hence, they contain 23 chromosomes.

6. The correct answer would be an option J.

Sperm formation or spermatogenesis is the process by which spermatozoa (haploid gamete) is produced from germ cell with the help of meiotic division.

Meiosis results in the formation of four haploid (n) cells from single diploid (2n) parent cell. Here, 2n is given as 8 so, n would be equal to 4.

Meiosis I results in the formation of two secondary spermatocyte cells (both haploid or 4 chromosomes in this case) from single primary spermatocyte (diploid or 8 chromosome in this case).

Both the secondary spermatocytes undergo meiosis II to produce 4 spermatids (each haploid or 4 chromosome in this case). Spermatids differentiate and mature into spermatozoa.

Answer:

it is might be wrong....

Explanation:

Third-trimester ultrasounds can examine the placenta and the position of the fetus. Sometimes an ultrasound is part of a test called a biophysical profile (BPP) to see whether the fetus is getting enough oxygen. The BPP examines the baby's breathing, movement, amount of amniotic fluid, tone, and heart rate response.

1. Which of the following would be expected to be true of parallel universes? Choose all that apply. *
Svetradugi [14.3K]

The property which would be expected to be true of a parallel universe would be that: They would have the same laws of physics.

Discussion:

A parallel universe by definition is; a separate universe or world that coexists with our known universe but is very different from it. a realm of existence and experience that is fundamentally different from the one that most humans share; a separate reality ultimately.

PS: Plato reflected deeply on the parallel realities, resulting in Platonism, in which the upper reality is perfect while the lower earthly reality is an imperfect shadow of the heavenly.
