Scilla [17]

Answer:

Option B, Move closer to your home town

Explanation:

The options for the given question are as follows -

A) Knock down your previous house and build a bigger one.

B) Move closer to your home town.

C) Move further away from your home town.

D) Stay where you are but speed up your daily life

Solution -

Electrons carry negative charge while nucleus carries positive charge due to the presence of positively charged proton ions and neutral ions (which has no charge). All the electrons are attracted towards the nucleus due to its positive charge. The orbit on which an electron revolves around a nucleus has higher energy level as compared to the energy levels located in between the space of electron and nucleus.  

While moving from a high energy orbital to a low energy level orbital, an electron releases some energy.  Hence, in order to move closer to home, electron needs to push itself toward the nucleus by releasing energy

Hence, the given option is B

Answer:

Twin studies document similarities and differences between twins. When two IDENTICAL twins raised under very DIFFERENT circumstances display similar personality traits, that suggests a strong GENETIC influence on personality.

ycow [4]

Answer:

The process of reuptake occurs when the sending neuron normally reabsorbs excess neurotransmitter molecules.

Explanation:

The process of reuptake takes place when a cell that initially produced and emitted a particular substance reabsorbs it again. Serotonin is one of the secretions affected by this process since it can be reabsorbed if it sticks to receptors located in the original nerve where it was produced to be then released once again.

A group of environmentalists was discussing the benefits and drawbacks associated with using fossil fuels. Which argument best f
tekilochka [14]

Answer:

The correct answer is - Fossil fuels are cheaper than alternative forms of energy.

Explanation:

Fossil fuels are made by the natural process in a longer time period such as anaerobic decomposition of the dead organism like plants, and animals. These plants and animal's decomposed organic matter pilled up to form coal, or natural gases or crude oil.

By the use of such fuels the reserves are continuously depleting and will be no longer available in the future if not managed properly as it can not be renewed. Fossil fuels increases the green house gases in environment and affect it by incresing carbon in atmosphere. However, these fuels are cheaper in comparision of other fuels.

Thus, the correct answer is - Fossil fuels are cheaper than alternative forms of energy.
