Research appropriate treatment for bacterial meningitis and describe a comprehensive plan to treat those affected as well as pre

Andrej [43]

Treatment

Meningitis is an infection of the membranes, meninges that surrounds and protects the central nervous system (the brain and spinal cord). Bacterial meningitis must be treated immediately with intravenous antibiotics and sometimes corticosteroids and, of course, the antibiotic depends on the type of bacteria causing the infection.

Prevention

First of all, to prevent the spread of bacterial meningitis it is important to practice good hygiene, such as frequent handwashing. Since the factors that increase the risk include spending time in communities (school, campus or college) because it spreads easily, children should be aware and vaccinated. As several types of bacteria can cause bacterial meningitis, a range of vaccines is wide (e.g. meningococcal vaccine, Hib vaccine).

Recent photographs of the planet Mars reveal deposits that suggest the former presence of liquid water. How does this compare wi

kolezko [41]

Answer with Explanation:

Let's start first with water on the Earth's moon. This is called "lunar water."

The moon was thought to be barren by scientists long time ago. However, they found out that there are actually water reserves located in the shadowed craters. It is said that the formation of this water was possible with the existence of Oxygen atoms in the lunar rocks and minerals. Due to the solar wind that blew into the place, the Hydrogen ions from the wind combined with the Oxygen in order to form water. So, the water that is found here is relatively fresh.

Let's go to "water on Mars." This is said to be more older than the water on the moon and is actually not that pure for it consists of some mixtures of rocks. It is said that billions of years ago, Mars had an abundant supply of water, but due to climate change, the supply didn't last long. As a result, the planet dried out and only the areas in the polar and mid-latitude regions have water (in the form of ice). This ice melts and refreezes, depending on the temperature. This is an evidence that people may possibly live on Mars.

An individual heterozygous for eye color, skin color, and number of eyes mates with an individual who is homozygous recessive fo

sukhopar [10]

Answer:

B) 1 black eyes, green skin, two eyes : 1 black eyes, green skin, one eye : 1 black eyes, white skin, two eyes : 1 orange eyes, green skin, two eyes : 1 orange eyes, white skin, two eyes : 1 orange eyes, white skin, one eye

Explanation:

Parentals: BbGgCc x bbggcc

The punette square diagram of the cross of these two parents is attached.

B = black eyes, b = orange eyes;

G = green skin, g = white skin;

C = two eyes, c = one eye

Progeny with BbGgCc genotype → black eyes, green skin, two eyes = 8

Progeny with BbGgcc genotype → black eyes, green skin, one eye = 8

Progeny with BbggCc genotype → black eyes, white skin, two eyes = 8

Progeny with bbGgCc genotype → orange eyes, green skin, two eyes = 8

Progeny with Bbggcc genotype → black eyes, white skin, one eye = 8

Progeny with bbGgcc genotype → orange eyes, green skin, one eye = 8

Progeny with bbggCc genotype → orange eyes, white skin, two eyes = 8

Progeny with bbggcc genotype → orange eyes, white skin, one eye = 8

So, if we will see them in the form of ratio then each of the genotype will be in the ratio of 1 i.e. black eyes, green skin, two eyes: black eyes, green skin, one eye: black eyes, white skin, two eyes: orange eyes, green skin, two eyes: black eyes, white skin, one eye: orange eyes, green skin, one eye: orange eyes, white skin, two eyes : orange eyes, white skin, one eye = 1:1:1:1:1:1:1:1.

So, in view of above option B is most appropriate.

Note: In a trihybrid cross, a total of 64 progeny types may be produced.

What is gravity and how does it influence objects?

Nimfa-mama [501]

Answer:

Gravity is the force by which a object or other body draws objects toward its center.

Explanation:

If I toss a ball into the air gravity will influence it and bring it towards its center, in this case the ground.
