Which of the following is NOT a consequence of China's one-child policy?
gizmo_the_mogwai [7]

Answer:

(B) Abortion, abandonment, and infanticide of males occur regularly.

Explanation:

China's one child policy was formed in 1979 with the aim to curb the increasing population of the country. Considered world's one of the most controversial methods to control population, it permitted couples to have only one child. As the traditional Chinese society preferred male child over female child, one child policy especially hit a blow to female population. Parents started to abort or abandon females because they wanted to have a male child and government did not allow a second child.

This move created a huge imbalance in sex ratio. Number of males increased drastically with respect to number of women. Males were not aborted and did not face abandonment as they were highly valued in society. The program was relaxed in 2013 and allowed rural couples and ethnic minorities to have 2 children and it was finally scraped off in 2015.

Why does DNA flow toward the positive electrode of the gel chamber?
Digiron [165]

Answer:

DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole.

Explanation:

Electrophoresis is a technique that <u>uses differences in electrical charge to separate the molecules in a mixture</u>. DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole. The rate of migration of a molecule depends on two factors, its shape, and its charge-to-mass ratio.

A gel, which is usually made of agarose, polyacrylamide, or a mixture of the two comprises a complex network of pores, through which the DNA molecules must travel to reach the positive electrode. The smaller the DNA molecule, the faster it can migrate through the gel. Gel electrophoresis, therefore, <u>separates DNA molecules according to their size.</u>

Gas makes things buoyant, why ? And what are ways that this could be useful?
ryzh [129]

Answer:

Gas makes things buoyant by making the volume of an object lighter than the surrounding fluid it is trying to displace.

Gas Buoyancy is useful in the following ways;

• Airships

• Steel ships and

• All floating and flying vessels

Explanation:

Buoyancy is the tendency of an object to float in a fluid such as air or water. It is a phenomenon that was theorized by the mathematician, Archimedes known as the Archimedes Principle.

It states that the upward buoyant force that is exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces.

The principle explains the reason why objects float and fly.

So, when an object is immersed in a fluid, it can float due to the upward force exerted by the fluid on the object. But for this to happen, the object has to weigh less than the fluid it is displacing.

This is where the use of a gas comes into play.

Because the object may be heavier than the surrounding fluid it is trying to displace, it is filled with a large amount of gas (usually hydrogen and/or helium) which is lighter. This makes the volume of the gas and the object put together lighter than that of the surrounding air.

This is what causes objects to float or fly

Mechanical digestion, the process of breaking down large chunks of food into smaller pieces, is important because smaller pieces
TEA [102]
The answer is Have a large surface area on which chemical enzymes in the digestive system can act on it<span>. This increases the rate of digestion and absorption of the nutrients. The smaller an object is, the larger the surface area to volume ration it has compared to relatively larger objects.</span>
