Answer:

Position Effect

Explanation:

Position effect is referred to the effect on gene expression when the gene is translocated from the location it is on a chromosome to another location.

As it relates to gene silencing and euchromatic gene repositioning, Position effect variegation best explains it.

Position effect variegation occurs when a gene in some cells is silenced as a result  of rearrangement of chromosomes which translocate or reposition euchromatic genes close to vicinity of heterochomatin. It is this abnormal chromosomal juxtaposition that leads to the gene silencing in stochastic pattern.

How does elevation affect climate?
postnew [5]

Altitude affects weather determines how dense the air is and how much heat energy the air can hold.

Option C is the correct one.

<h3>What is the relationship between authority and climate?</h3>

The relationship between climate and altitude is manifested through variations in atmospheric pressure and temperature. Although higher locations are closer to the sun, they tend to receive less heat, becoming colder, in addition to having a smaller thermal amplitude (temperature variation).

With this information, we can conclude that Higher elevations cause temperatures to drop because the higher up in the atmosphere you go the colder it gets due to air pressure in turn causing precipitation to freeze creating snow.

___ 1. When the combined effect of two drugs, each producing the same biological response by the same mechanism of action, is eq
Valentin [98]

Answer:

Additive effects

Explanation:

In pharmacology, sometimes more than one drug is used to treat a disorder. The two or more drugs are used as they treat the disease more effectively than they treat the disorder independently.  The two drugs interact in one of the two ways: the additive effect and the synergistic effect.

In the given question, the drugs when combined produce the sum of the drugs equal to the effect shown by the drugs individually therefore the effect of the drug is added. This type of drug interaction is known as the additive effect.

Thus, Additive effect is the correct answer.

Why 90% of all marine life is found in the upper 180 meters of the ocean?
Aleks [24]
In lieu with your question, only 10% marine life are adapted to withstand the immense hydro-static pressure below 180 meters. Other 90% are adapted to live in surface of  ocean or on their evolutionary way to land.
