kakasveta [241]

The human population has changed since it first appeared on earth as The b. population has generally increased, and at rates that have varied over time.

Humans, as well as other populations, have changed since their appearance on earth. Some populations became extinct as they were not able to cope with the environmental changes whereas other became more adaptable and increased in number over time.

The human population has also increased with the passage of time. However, the increase in the rate of the human population was not a stable one. At some times in the past, the population number declined due to environmental factors such as the eruption of a disease etc.

However, with the passage of time, humans have managed to adapt themselves to the changing environmental conditions and their population is increasing rapidly.

Although a part of your question is missing, you might be referring to this question:

The human population has changed in ways that are similar to other populations. How has the human population changed since it first appeared on earth?

a. The population has generally increased at a relatively constant rate

b. the population has generally increased, and at rates that have varied over time

c. The population increases rapidly until it reaches carrying capacity, where it has remained for thousands of years

d. The population increases rapidly until it reaches carrying capacity, and then decreased at a constant rate

___ 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.

Thymine = 2,4-dioxy-5-methyl pyrimidine

Cytosine = 2-oxy-4-amino pyrimidine

Orotic acid = 2,4-dioxy-6-carboxy pyrimidine

Polynucleotides

Nucleotides are joined together by 3'-5' phosphodiester bonds to form polynucleotides. Polymerization of ribonucleotides will produce an RNA while polymerization of deoxyribonucleotides leads to DNA.
