Answer: When the egg is not fertilized.

Explanation:

Menstruation can be defined as the biological phenomenon in which the inner lining of uterus sheds along with mucosal tissue and blood.

It starts at the age of puberty and ends at the age between 45 to 50. When the body prepares uterus for pregnancy it releases eggs from ovary and thickens the uterus for implantation.

But when the eggs are not fertilized, then it is shed off from the uterus known as menstruation which lasts from 2-7 days every month.

As far as humans are concerned a period is a bleed from the womb (uterus) that is released through the vagina. Women have a period every 28 days approximately. However, some women may have a 24-day cycle while other may have a 35-day one. A period is part of the woman's menstrual cycle

A scientist who studies teenage behavior was interested in determining if teenagers spend more time playing computer games then

natita [175]

Answer:

greater than 0.10

Explanation:

The null hypothesis is:

$H_{0} = 10.2$

The alternate hypotesis is:

$H_{1} > 10.2$

Our test statistic is:

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the statistic, $\mu$ is the mean, $\sigma$ is the standard deviation and n is the size of the sample.

We have that:

$t = 0.45$

We are testing if X is greater than 0.45, so our pvalue is 1 subtracted by the pvalue of z = t = 0.45.

z = 0.45 has a pvalue of 0.6736

1 - 0.6735 = 0.3264

So our pvalue is 0.3264, which is greater than 0.10.

So the correct answer is:

greater than 0.10

A light meterstick is loaded with masses of5.0 kg and 3.0 kg

fredd [130]

Answer: $I=3.024\ kg-m^2$

Explanation:

Given

mass of first $m_1=5 kg$

mass of second $m_2=3 kg$

Distance of $m_1$ from origin $r_1=36 cm$

Distance of $m_2$ from origin $r_2=89 cm$

Moment of inertia is given by multiplication of mass and square of distance

$I=\sum mr^2$

$I=m_1r_1^2+m_2r_2^2$

$I=5\times 0.36^2+3\times 0.89^2$

$I=0.648+2.376$

$I=3.024\ kg-m^2$

Iron-rich minerals in rock pointed in one direction and then switched to the exact opposite direction. This supports what idea?

NISA [10]

Iron rich minerals in rock pointed in one direction the switch to the exact opposite direction. I'd say that what supports this idea is that Earth's magnetic field goes through pole reversals.
