Answer:

A. Eight

Explanation:

Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships.

Answer:

d) 2

Explanation:

We are given;

n = 4, l = 1, m = -1

We can tell that is is an orbital with sub shell as 3P.

Now, from Paul's exclusion principle, each orbital will have maximum of 2 electrons of each π with a spin of +½ and -½.

Since the maximum is seen to be 2, then option D is correct.

Answer:

Gases, liquids and solids are all made up of microscopic particles, but the behaviors of these particles differ in the three phases. Gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

Answer:

Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size. This transformation produces three general classes of rock: igneous, sedimentary and metamorphic. Those three classes are subdivided into many groups.

B. by finding its speed and direction

Kinetic energy is the energy an object has due to its motion. As long as an object is moving at the same velocity, it will maintain the same kinetic energy. The kinetic energy of an object is calculated from the velocity and the mass of the object.

Answer:

I think number D is correct

Answer:

D. Certain blood vessels are blocked by fatty acids

Explanation:

A heart attack occurs when the flow of blood to the heart is blocked. The blockage is most often a buildup of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries). Sometimes, a plaque can rupture and form a clot that blocks blood flow.

Explanation:

The mechanism involves SN1 nucleophilic substitution reaction. The -OH group of the alcohol is first protonated. Since water is a good leaving group, -OH2 leaves the substrate creating a primary carbo cation.

A 1,2 methyl shift now occurs to create a tertiary carbo cation which is more stable leading to the major product shown in the image attached to this answer.

Answer:

Different visible waves show different colors

In the electromagnetic spectrum, different  visible waves show different colors.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Answer: The products of electrolysis are Zn(l) and [tex]Cl_2[/tex] gas

Explanation:

Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.  

In the electrolysis of molten zinc chloride, zinc metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.

[tex]ZnCl_2(l)\rightarrow Zn^{2+}+2Cl^-[/tex]

At anode : [tex]2Cl^-(l)\rightarrow 2e^-+Cl_2(g)[/tex]

At cathode : [tex]Zn^{2+}(l)+2e^-\rightarrow Zn(l)[/tex]

Answer:

0.01 M

Explanation:

NaOH (sodium hydroxide) is a strong base, so it is completely dissociated into ions in aqueous solution:

NaOH ⇄ Na⁺ + OH⁻

So, we have OH⁻ ions in solution.

From the problem, we have the pH value. The pH is calculated as:

pH = -log [H⁺]

As NaOH is a base, we can also calculate the pOH:

pOH = -log [OH⁻]

Thus. we can use the relation between pH and pOH to calculate the pOH and then use it to calculate [OH⁻]:

pH + pOH = 14 ⇒ pOH = 14 - pH = 14 - 12.05 = 1.95

pOH = -log [OH⁻] ⇒ [OH⁻] = [tex]10^{-pOH}[/tex]= [tex]10^{1.95}[/tex]= 0.0112 M ≅ 0.01 M

Answer:

0.0112

Explanation:

They said that was the answer.

Answer/Explanation:

f is the number of waves produced by a source per second, it is measured in hertz (Hz). T is the time it takes for one complete oscillation, it is measured in seconds. All waves, including sound waves and electromagnetic waves, follow this equation. A radio wave has a time period of 0.0000003333333 seconds.

Explanation:

a metal is an element that readily forms positive ions (cations) and has metallic bonds.

Group two of the periodic table comprises the elements beryllium, magnesium, calcium, strontium, barium and radium. The elements in this group, which are all shiny and silvery-white in appearance, are known as the alkaline earth metals. Like the alkali metals, they form alkaline solutions when they react with water.

Hello. You forgot and show the compounds. The compounds are in the attached image.

Answer:

I < II < III

Explanation:

The stability of the presented compounds must be analyzed, taking into account the free electrons to form arrangements between the atoms. In this case, the molecules of greater stability follow the concept of valence and are characterized as those that manage to reach a large number of elements that manage to obey the octet rule.

Answer:

Balloon will burst

Explanation:

The amount of volume that can be held by the latex will reduce yet the volume of air inside does not change. therefore the air inside will force the latex to break.

Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it then balloon will burst.

latex is what latex balloons are made of. Due to tiny microscopic holes in the latex, it is porous and does not hold helium for as long as foil balloons (mylar balloons).

While latex balloons usually float for only 8–24 hours, foil balloons typically float for 4–21 days. But you can actually get a latex balloon to float longer than a foil balloon by using a product called hi-float, which extends the life of a latex balloon by 25 times the average float time.

In addition to being available in a variety of colors and prints in sizes ranging from 5" to 3 feet, latex balloons can also be printed in many colors, however if you want a detailed design you really need to use foil balloons.

Therefore, Assume that you tie the balloon to prevent air from escaping and then squeeze the balloon with one hand, so there is less space inside it then balloon will burst.

Answer:

Your nervous system is your body's command center.

Explanation:

since it is originated from your brain, it controls your movements, thoughts and automatic responses to the world around you.

Yes, As the gravity/distance increases between two objects, the gravitational pull between them weakens/strengthens.

There is a gravitational force of attraction between every object in the universe. The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases.
