In a perfect world, reciprocal classes would be equally represented since they result from the same meiotic event. It is likely

that your data suggests the parental classes are NOT equal.
What causes this phenomenon to occur? (Think about the phenotype of each.)

Answer:

Regarding the genotype and phenotype of the original parents they are known by the name of parental classes. These parental classes have appeared of the genotype are classified as homozygous or heterozygous.

Explanation:

While the reciprocal classes are also the genotypes and phenotypes of the crosses. These reciprocal classes are personified if the crossing occurs between the homozygous alleles. This is due to the fact that the chromosomal part is exchanged in the two chromosomes, since the cross products are the same as the products that are formed in the parent classes, this occurs in a phenomenon known as homozygosity.

In the event that the crossover occurs in a heterozygous allelic tetrad, then an exchange between the different chromosomal parts will occur, resulting in recombinant alleles. In this particular case, the parenting classes cannot be the same. This phenomenon is known as heterozygosity.

1. Which force is being applied by a vendor when he is pushing the pushcart? *
marta [7]

Answer:

1. Muscular force

2. Speed decreases

3. higher than

4. decreases

5. air pressure

6. Inversely proportional to the area of contact

7. 20 N

8. 400 N / m2

9. 150 N

10. friction

Explanation:

1. During pushing the pushcart the person is required to use strength of his arms and legs muscles that will creat a force between the surfaces, hence the force used is muscular force.

2. The speed of car decreases while applying brakes because a friction is generated between the brakes and the wheel that reduces the kinetic energy of vehicle and decreases the speed of the vehicle.

3. The pressure of the water at the bottom of the pond is higher than at the surface of pond because water pressure increases with the depth of the water. Water pressure increases in the depth because weight of water over the body icreases as going deep.

4. At higher altitude the atomspheric pressure decreases because as the height in atmosphere increases the amount of  air molecules decreases and so, less oxygen for breathing.

5. Air pressure allows the dropper to fill inks as dropper exerts a force on a surface of ink and due to the low pressure inside the dropper sucks up the liquid.

6. Pressure is defined as the perpendicular force exerted at the surface or it means force per unit area. Pressure is directly proportional to the force and inversely proportional to area of contact.

7.  The boys exerts pressure in opposite direction on an object, hence the resultant force will be

   resultant force = force 1 - force 2 = 60N−40N=20N.

8. pressure (P) is equal to force (F) per unit area (A)

P =  F / A

    = 800 / 2

    = 400 N / m2

9. Pressure (P) = 300 Pa    

    Area of Cross-section (A) = 0.5 m²

    Force = P × A

               = 300 × 0.5

               = 150 N

10. Friction is the force that is always applied against or opposite to the moving direction of an object. Friction is responsible to stop the movement of any moving object such as vehicles and sliding objects.

Hence, the correct option of the questions are:

1. Muscular force

2. Speed decreases

3. higher than

4. decreases

5. air pressure

6. Inversely proportional to the area of contact

7. 20 N

8. 400 N / m2

9. 150 N

10. friction

Which of the following is a true statement about lava that contains large amounts of dissolved gases? Lava that produces violent
anygoal [31]

<u>Answer:</u>

<em>The dissolved gases produce violent eruption as they escape. </em>

<u>Explanation:</u>

Magma contains dissolved gases and these dissolved gases induce vapor <em>pressure on the magma.</em> The magma is able to remain in the dissolved state itself without erupting because this vapor pressure is less than the confining pressure of the <em>rock surrounding the magma. </em>

One the vapor pressure exceeds this confining pressure the dissolved gases begin to  expand and<em> forms small gas bubbles</em>.

The <em>density of these gas bubbles</em> called vesicles is less than the density of magma and thus naturally tries to push out. When the gas bubbles escape the magma is also pushed out. Thus greater <em>amount of dissolved gases result in violent eruptions. </em>

What might happen if you make a hole using a pointed object to any of the two small<br> balloons?
luda_lava [24]

Answer:If the balloons are filled with air all of the air will try and escape from the balloon out of the hole but if the balloon is filled very tightly with air it will burst because there is too much pressure trying to escape such a small hole so it goes PoP!

Explanation:

Not researched this answer was from common knowledge so if you have a correction or better answer please inform me I will be happy to learn more.
