Answer:

D.  It is released during menstruation

Explanation:

The egg that is not fertilized is  released during  the process of menstruation​.

Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone levels and is a sign that pregnancy has not occurred.

The first period, a point in time known as menarche, usually begins between the ages of 12 and 15.Menstruation starting as young as 8 years would still be considered normal.The average age of the first period is generally later in the developing world, and earlier in the developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women. In adults, the range is between 21 and 31 days with the average being 28 days.

Answer:

The tetanus vaccine is a dose of the bacterium Clostridium Tetani, in inactive form or even a surface molecule that helps the body to actively form the antibody.

The tetanus vaccine has coverage for life, it is mandatory in those countries where the disease became common, such as the USA, Argentina, Chile, Uruguay among others.

Before a surgical act or a suspicion of exposure with this bacterium, the booster of the tetanus vaccine should be administered quickly.

Explanation:

Tetanus disease generates a tetanization of all the muscles of the organism, generating spasmodic contractions, which make it impossible to function and develop life when it affects the diaphragm as it makes breathing impossible.

Tetanization does not affect differently in age or sex, it only consists of contamination with the bacteria to be sufficient.

The sources of contagion are areas of mud or earth, rusty cutting or sharp elements, and poorly hygienic or abandoned areas. In order for the bacteria to be transmitted or the transmission route to be fulfilled, there must be a lesion of loss of continuity of the epithelium or mucosa.

Answer:

The egg is the dependent variable and the salt is the independent variable.

Explanation:

The dependent variable is something that stays the same throughout the experiment. The independent variable is something that might not stay the same throughout the experiment. The egg does not change because we're using an egg and not an egg and then a tomato or a potato, but the salt does change because we're changing the amount of salt in the bowl/plate or anything else that we are using to perform this.

This is kinda long but it explains mostly everything. DM me for more dependent and independent variable help.

The question is incomplete, the complete question is:

Regina conducted an investigation to determine whether earthworms add nutrients to soil. She used two pots of soil. She added three earthworms to the first pot. She did not add any earthworms to the second pot, which was the control. Regina tested the nutrient levels of the soil in both pots after two weeks.

What type of investigation is Regina conducting?

descriptive

comparative

experimental

procedural

Answer:

experimental

Explanation:

In an experimental study, there is an independent variable, a dependent variable and a set up meant for control.

The control is set up to establish the validity of the study.

Experiments are designed to establish cause and effect relationship. In this case, the experiment was designed to establish weather earthworms add nutrient to the soil.

Answer:

[tex] C_{H_{2}} = 0.07 M [/tex]

[tex] C_{I_{2}} = 1.07 M [/tex]

[tex] C_{HI} = 1.86 M [/tex]

Explanation:

The reaction is:

H₂(g) + I₂(g) ⇄ 2HI(g)

Initially, we have the following concentrations of H₂ and I₂:

[tex] C_{H_{2}} = \frac{n}{V} = \frac{1 mol}{1.00 L} = 1 mol/L [/tex]

[tex] C_{I_{2}} = \frac{n}{V} = \frac{2 mol}{1.00 L} = 2 mol/L [/tex]

Then, in the equilibrium we have:

H₂(g) + I₂(g) ⇄ 2HI(g)

1-x       2-x         2x

[tex] Kc = \frac{[HI]^{2}}{[H_{2}][I_{2}]} = \frac{(2x)^{2}}{(1-x)(2-x)} [/tex]

[tex] 50.5*(1-x)(2-x) - (2x)^{2} = 0 [/tex]

By solving the above equation for x we have:

x₁ = 2.32 and x₂= 0.93

Hence, the concentrations of H₂, I₂ and HI are:

[tex] C_{H_{2}} = 1-x = 1 - 0.93 M = 0.07 M [/tex]

[tex] C_{I_{2}} = 2-x =  2 - 0.93 M = 1.07 M [/tex]

[tex] C_{HI} = 2*x = 2*0.93 M = 1.86 M [/tex]

An ionic charge of 2-

Explanation:

The number of electrons is 8 and the number of protons is 2, subtract the two and the difference is the ionic charge. Hope this helps! :)

Answer:

This answer would be 2

Explanation:

The way that I have always done it is you put protons in tally marks (without crossing) over the top of the neutrons and mark them out one by one and whichever one that you have leftover that is your charge.

Hope this helps!

Answer:

Answer:

An ion is charged because the number of electrons does not equal the amount of particles.

Explanation:

Can be positive (meaning more protons than electrons) and it can be negatively charged (meaning there are more electrons than protons).

Hope this helps!

Answer:

An ion has a charge because the number of electrons dont equal the amount of protons in the molecule or atom.

Explanation:

The negative or positive charge depend on wether the atom or molecule has more electrons(-) or protons(+).

This is the central theme of Rutherford's experiment on a thin gold foil.

Answer:

Which indicates that thermal energy is no longer being transferred from boiling water to a mug?

The mug and the water lose all thermal energy.

The water is hotter than the mug.

The mug is hotter than the water.

•The water and the mug are the same temperature.

Explanation:

answer #D is correct

When the water and the mug are at the same temperature then thermal energy will no longer be transferred from the boiling water to the mug. Therefore, option (D) is correct.

Thermal energy is generated in a substance when an increase in temperature causes atoms and molecules to move at a faster speed and result in the molecules colliding with each other. The energy generated from the temperature of the heated material is called thermal energy.

Thermal Energy or internal kinetic energy is because of the random motion of molecules in the system. The thermal energy of any system is directly proportional to its temperature.

The more the temperature of the system, the more the movement of molecules within a given system, and the more the thermal energy of the system.

The thermal energy will be transferred from the boiling water to the mug when the water is hotter than the mug. When both have the same temperature then the thermal energy is no longer being transferred from boiling water to a mug.

Answer:

A) one electron in each orbital

Explanation:

Orbitals get electrons one at a time. If there are three electrons and three empty orbitals, then one electron will go into one orbital!

The state change occurs when the glass melts.

The matter is anything that has mass and occupies space.

The different states of matter are solid, liquid, gas, and plasma.

The properties of the different types of matter can be understood by looking at the arrangement of molecules.

When a solid substance is heated beyond its melting point, it changes its state from solid to liquid.

When liquid is heated beyond its vaporizing point, it changes its state from liquid to gas.

Solids are closely packed and have a definite shape and size.

Liquids are loosely packed and take up the space of the container.

Gas has high intermolecular spacing and the gases are not rigid.

Ground glass is melted under light heat and poured into molds.

Recycling glass involves changing the state of glass from solid to liquid state.

In such a conversion, we use the molar mass of a substance as a factor to convert that to mole units into mass units (or, conversely, mass units into mole units).

Then We also established that 1 mol of Al incorporates a mass of 26.98 g (Example). Stated mathematically that is, 1 mol Al = 26.98 g Al

Now, This relation provides a factor to travel from grams to moles.

which is help to Using the factor 98.08 g / 1 mol: grams H 2 SO 4 = 3.60 Then mol x 98.08 g / 1 mol = 353 g H 2 SO 4
