How are viruses able to infect cells?

Biology
1 answer:
sasho [114]4 years ago

Answer: Viruses infect cells by entering the cell almost disguising itself as a positive cell or object if you will. Once the virus is inside and the cell absorbs it thinking it is food or something else god knows what, the virus then replicates its DNA into the cell, replacing the RNA and infecting the cell, which then begins to multiply. Good Luck!

What are the sequence of steps that includes the image on the retina
jonny [76]

Answer: Light goes into the eye via the cornea, it then pass through the pupil, the lens, the vitreous humor and finally forms an image on the retina.

Explanation:

Light goes into the eye via the cornea. The cornea is a clear, dome-shaped surface that covers the front of the eye.

From the cornea, the light passes through the pupil. The pupil regulates the amount of light passing through.

From the pupil, , light hits the lens. The lens is the clear structure inside the eye. It focuses light rays onto the retina.

Subsequently, light passes through the vitreous humor. A clear, jelly-like substance that fills the center of the eye. It helps to keep the eye round in shape.

Finally, the light reaches the retina where the image is formed the image is usually inverted. The retina is a light-sensitive nerve layer that is situated at the back of the eye.

The main function of the optic nerve is to carry the signals to the visual cortex of the brain. The visual cortex turns the signals into images.

Answer:

2c. Jamestown Settlement and the "Starving Time"

Explanation:

The first joint-stock company to launch a lasting venture to the New World was the VIRGINIA COMPANY OF LONDON. The investors had one goal in mind: gold. They hoped to repeat the success of Spaniards who found gold in South America.

In 1607, 144 English men and boys established the JAMESTOWN colony, named after King James I.

The colonists were told that if they did not generate any wealth, financial support for their efforts would end. Many of the men spent their days vainly searching for gold.

As a consequence, the colonists spent little time farming. Food supplies dwindled. MALARIA and the harsh winter besieged the colonists, as well. After the first year, only 38 of the original 144 had survived.
