There are 4 electrons altogether shared between carbon atoms in a molecule of C2H4, to be more precise there are 2 electron pairs shared between the carbon atoms.
The answer is <em>A.) You have antibodies that already recognize the virus</em>
Viruses and diseases are always changing. When we get sick with say the flu, a virus, or the cold of sorts, our body attacks it until it fights off the disease. You can't get sick from the same strand of sickness because once your body defeats the virus, it knows how to protect the body from it because of the antibodies, so the virus ends up evolving to get past your immune system again.
I hope this helped! Have a wonderful day :)

Sam, Tim, Bella and Joshua on the grounds that the red in Lisa is the partial blindness and they're the main individuals with the full shading red shaded.

Explanation:</u></h3>
Red green visual impairment is a x connected characteristic, which implies that it is found on the X chromosome. X connected attributes are frequently latent, and this is the reason they for the most part appear in guys, for example, the instance of red green colorblindness.
A male has just a single duplicate of the X chromosome, so if a passive x connected characteristic is available, he doesn't have the alternative of the prevailing rendition of the quality to appear.
A latent X connected attribute can introduce itself in a female, yet since she has two X chromosomes, she would need two duplicates of the passive quality for it to introduce itself.
This is the reason visual impairment is less normal, yet at the same time conceivable in females. I trust this encourages you with your family.
Nestled at the edge of the arid Great Basin and the snowy Sierra Nevada mountains in California, Mono Lake is an ancient saline lake that covers over 70 square miles and supports a unique and productive ecosystem. The lake has no fish; instead it is home to trillions of brine shrimp and alkali flies. Freshwater streams feed Mono Lake, supporting lush riparian forests of cottonwood and willow along their banks. Along the lakeshore, scenic limestone formations known as tufa towers rise from the water's surface. Millions of migratory birds visit the lake each year.
From 1941 until 1990, the Los Angeles Department of Water and Power (DWP) diverted excessive amounts of water from Mono Basin streams. Mono Lake dropped 45 vertical feet, lost half its volume, and doubled in salinity.
The Mono Lake Committee, founded in 1978, led the fight to save the lake with cooperative solutions. We continue our protection, restoration, and education efforts today with the support of 16,000 members --and we host this Website.
In 1994, after over a decade of litigation, the California State Water Resources Control Board ordered DWP to allow Mono Lake to rise to a healthy level of 6,392 feet above sea level--twenty feet above its historic low. It is rising toward that goal -- click here for the current lake level, or visit one of the other links on this page for more of the Mono Lake story.
