Because your uterus prepares to carry a baby every month and when you are not pregnant it has to get rid of the sack and all of the preparations that it made and do it all over again next month

Well, for one thing, it's your body's way of preparing for pregnancy. Once you get your period, it means that you are physically able to become pregnant and have a baby – although you don't necessarily feel ready!

Periods happen as a result of hormones released from a gland at the base of your brain called the pituitary gland. These hormones cause an egg to be released. At the same time, the lining of your uterus (or womb) is becoming thicker – like a soft and spongy bed, ready for the egg.

What kind of bond is formed when one atom steals an electron from another atom
Delicious77 [7]
Ionic bonds <span>are the type of bonds where there is </span>transfer<span> of electrons from one atom to another.  The electrons are removed and from one atom and attached to  another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.</span>

8. Which of the following statements is true about meiosis?
Mariulka [41]

Answer:

B

Explanation:

Meiosis produces gametes that contain one complete haploid set of chromosomes

Meiosis is a reduction division, where the number of chromosomes in the daughter cells is reduced to half as compared to the parent cell. This set of chromosomes is called a haploid set or genome. The reduction from diploid to haploid occurs during Anaphase I of meiosis I, where homologous chromosomes separate and enter into two different cells. Meiosis takes place only in reproductive cells that divide to form gametes

So, the correct answer is 'Meiosis produces gametes that contain one complete haploid set of chromosomes'

hope that helps
