What part of the brain is highlighted in the diagram below?

Which of the following statements best provides evidence of the big bang theory?

Oxana [17]

Answer: D. Galaxies show a red shift, indicating they are moving away from each other.

Explanation:

Galaxies seem to show a red shift which indicates that the galaxies are moving away from each other. This provides evidence for the Big Bang theory because the theory posits galaxies will keep moving away from each other.

This is because when an explosion happens, matter moves away from the point where the explosion happened. If the Big Bang happened therefore, galaxies will move away from the source which is why galaxies are moving away from each other.

What would you do if you found out that you contracted a deadly bacterium/ virus?

gizmo_the_mogwai [7]

Answer:The plague is a serious bacterial infection that can be deadly. Sometimes referred to as the “black plague,” the disease is caused by a bacterial strain called Yersinia pestis. This bacterium is found in animals throughout the world and is usually transmitted to humans through fleas.

The risk of plague is highest in areas that have poor sanitation, overcrowding, and a large population of rodents.

In medieval times, the plague was responsible for the deaths of millions of people in Europe.

Today, there are only 1,000 to 2,000 casesTrusted Source reported worldwide each year, with the highest incidence in Africa.

Plague is a rapidly progressing disease that can lead to death if untreated. If you suspect you have it, call a doctor right away or go to an emergency room for immediate medical attention.

Types of plague

There are three basic forms of plague:

Bubonic plague

The most common form of plague is bubonic plague. It’s usually contracted when an infected rodent or flea bites you. In very rare cases, you can get the bacteria from material that has come into contact with an infected person.

Bubonic plague infects your lymphatic system (a part of the immune system), causing inflammation in your lymph nodes. Untreated, it can move into the blood (causing septicemic plague) or to the lungs (causing pneumonic plague).

Septicemic plague

When the bacteria enter the bloodstream directly and multiply there, it’s known as septicemic plague. When they’re left untreated, both bubonic and pneumonic plague can lead to septicemic plague.

Pneumonic plague

When the bacteria spread to or first infect the lungs, it’s known as pneumonic plague — the most lethal form of the disease. When someone with pneumonic plague coughs, the bacteria from their lungs are expelled into the air. Other people who breathe that air can also develop this highly contagious form of plague, which can lead to an epidemic.

Pneumonic plague is the only form of the plague that can be transmitted from person to person.

How plague spreads

People usually get plague through the bite of fleas that have previously fed on infected animals like mice, rats, rabbits, squirrels, chipmunks, and prairie dogs. It can also be spread through direct contact with an infected person or animal or by eating an infected animal.

Plague can also spread through scratches or bites of infected domestic catsTrusted Source.

It’s rare for bubonic plague or septicemic plague to spread from one human to another.

The highlighted structure separates the oocyte from the externally located ________. zona pellucida primary follicle corona radi

Naya [18.7K]

Answer:

Granulosa cells

Explanation:

Foliculogenesis is a dynamic and complex process through which the follicle goes through many stages of development in a short period (approximately 60 days in humans and some chimpanzees).

The stages classification is based on morphological changes such as follicular size or diameter, the number of follicular cell layers, etcetera. These classifications might vary among authors but could be denominated as:

Primordial follicle

Primary follicle

Secondary follicle and

De Graaf follicles (This is the one shown in the image)

Through each stage, there are certain modifications in the oocyte, follicular cells, and connective tissue. As the oocyte grows, the follicular cells might reach a size twice or three times bigger than the ones of the primordial follicles. Their shape also changes and they adopt an aspect of stratified epithelium. Their cytoplasm gets a granulous aspect, after what these cells receive the name of granulous cells. The De Graaf follicle characterizes for having a space named follicular antro that displaces the oocyte to one of the sides.

The oocyte at this point gets surrounded by zona pellucida and corona radiata .

The follicular antro (The highlighted structure) separates the oocyte from the externally located granulosa cells or follicular cells.
