Answer:

Noble gases are likely to be least reactive, because they have complete octet in their valence shell.

Halogens are likely to be most reactive, because they want only one electron to complete its octet in their valence shell.

<span> 1.  Meningitis is an infection of meninges, the membrane that protects the brain. To prove there is an infection in the brain, you can take a specimen of cerebrospinal fluid by lumbar puncture. The sample can be examined microscopically (for the presence of bacteria and leukocyte) or chemically(by looking at the protein count).


2. Cerebrospinal fluid should be sterile so the presence of eukaryotic cells means that the patient is meninges infected by bacteria. The diagnosis probably is meningitis bacteria. The capsule indicates the bacteria is Neisseria meningitidis, make the diagnosis become meningococcal meningitis.
Meningitis could also caused by Listeria </span>monocytogenes, Haemophilus influenza, Streptococcus pneumoniae, or <span>a virus.

3. The site of infection of meningitis could be from blood or direct contact to the cerebrospinal fluid. 
Direct contact needs an open wound from the skull or the vertebrae that allow the invasion. Any accident that has enough force to fracture the skull be at risk.
</span>Bacteria can spread from blood in case of sepsis. Immunocompromised patient has a higher risk. Children, incomplete vaccination and living in high-density community also increase the risk.

Which of the following is not a natural cause of extinction?
dedylja [7]

Answer:

Introduction of Non-native species would be the answer. ( B )

Explanation:

Now let's break it down.

A. Competition due to overpopulation

Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.

B. Introduction of Non- native species.

So what does it mean by Non-native species?

It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.

C. Catastrophic Events

Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.

D. Disease

This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.

So, the Answer would be B.

The germ cell has 2 sets of chromosomes, and the four gametes will each have one set of chromosomes. ​​​​​​​ To have enough DNA
ICE Princess25 [194]

Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
