Well the flu is a virus. Knowing it’s a virus we know they multiply by entering a cell and passing over there rna then converted to be dna and creating other versions of them selfs until cytolysis occurs meaning the cell explodes with these new viruses and do the same with other cells. Since these dna conventions to create protein body parts of virus means there’s a increase in chemical reactions in the body and enzyme production. Also since your body has an immune system it can sense these antigens from the virus’s and cause increase in certain white blood cells to come in and kill these viruses and cells. In essence chemical and enzyme reactions increase. To survive.

Explain why the size of a new moon would affect the appearance of a solar eclipse.
USPshnik [31]

Answer:

A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.

HAPPY NEW YEARS !!! CAN SOMEONE PLEASEEEE HELP ME WITH THIS SCIENCE QUESTION I WILL MARK YOU BRAINLIEST !!!

Answer:

According to the image shown, the country that most closely resembles the population pyramid by age is the United States (option A).

Explanation:

The population pyramid consists of a bar chart that groups the population by age and sex. Each sex is separated into two columns, while from the base to the top the ages are grouped from lowest to highest.

The pyramid by age shown in the image corresponds to a developed country, such as the United States, since the distribution of the population of infants and young people is proportional, being more acute in the advanced ages, acquiring the shape of a bottle.

The "bottle" shape of the population pyramid indicates a controlled birth rate, as well as good availability of basic and sanitary resources, characteristic of a developed country like the United States.

The other options are not correct because:

<em>     C and D. In developing countries such as </em><u><em>Nigeria and Ethiopia</em></u><em>, the birth rate is high - forming a broad base - and the resources available are limited, so there is a progressive decrease as the age groups are distributed, giving a true pyramid shape. </em>

<em>     B. </em><u><em>Italy</em></u><em>, a European country, has a tendency to rhomboidal population pyramids. This is due to a predominance of adult, young and mature, population, low birth rate, good basic and sanitary resources.</em>
