Explanation:

A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.

The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.

Where do marine creatures store carbon in their bodies? What form is it in?

Answers

the tissues other than blood contain most of the CO2 stored in the body. Over 90 % of this tissue CO2 is stored in bone as carbonate (65, 155).

When they die, their carcasses sink to the seafloor, bringing a lifetime of trapped carbon with them. This is called Deadfall Carbon. On the deep seafloor, it eventually can be buried in sediments and potentially locked away from the atmosphere for millions of years.

What is the Environment?

The environment may be defined as a sum total of all forms of living and non-living elements and their consequences that significantly influence human life. It includes biotic and abiotic factors. The term environment is first given by Carlyle.

The protection of the environment requires a lot of actions by humans and the cooperation of other living organisms as well. All these actions impact the protection of the environment and improve energy efficiency along with the reduction in energy waste.

Therefore, improving energy efficiency and reducing energy waste is the best solution that meets energy demands while protecting the environment. Thus, the correct option for this question is D.

How do you think the Law of Universal Gravitation State connects why apples fall down and planets circle in orbit?

Answers

Apples are drawn to a massive object, like the earth, and fall down under a gravitational constant. On the other hand, planets revolve around a more massive object under the same premise. It’s the same idea, just one follows a linear path, and the other has a uniform circular motion path because other forces are acting on it. In other words, the planets ARE still falling, but the sun is also pulled by them so they just keep dancing.

You have to make sure all of your equipment is clean

Answer:

infection control- clean equipment to prevent spread of germs

All items needed for the operation should be in place and an adequate supply of regularly used items should be on hand to minimise movement to and from theatre during the operation

Everything needs to be sterile

All instruments need to be inspected for any signs of contamination after the sterilisation process

Shoes from outside should never be worn inside an operating room

Theatre hats are worn routinely, and prevent loose hair and skin from falling on wounds or equipment

D. Rocks on land

Answers

Answer:

D. rocks on land

Explanation:

Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.
