How many sex chromosomes does the normal human female inherit from her mother?

Biology
1 answer:
AveGali [126]3 years ago
4 0

Answer:

A. 1.2

Explanation:

Normally, a human body cell contains 46 chromosomes - 23 inherited from the father and the same number from the mother.

Most of the human DNA, or human genes, are located in the chromosomes.

Each metaphase chromosome consists of:

two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids;  two centromeres, one on each chromatid.

Difference between family planning and birth control
nexus9112 [7]
‘Family planning’ is a broad term that includes any measures taken to responsibly prevent pregnancy (birth control, contraception, planning, abortions, permanent infertility procedures, etc.).
Birth control, however, is specifically designed to intervene in a woman’s natural hormones to drastically reduce the possibility of pregnancy (much like contraception)

Volume is defined as the amount of mass that an object has? True or false
maria [59]

Answer:

False

Explanation:

Mass and volume are two different quantities. In fact:

- Mass is a scalar quantity representing the "amount of matter" contained in a certain substance. It is measured in kilograms (kg), which is one of the 7 fundamental SI units.

- Volume is a scalar quantity representing the amount of "three-dimensional space" occupied by an object or a substance. It is measured in cubic meters (m^3).

Therefore, mass and volume are two different quantities. They are related through another quantity called density, given by:

d=\frac{m}{V}

where

m is the mass

V is the volume

So the density of a substance represents the amount of mass contained in a certain volume of the substance.
