A bacterial isolate is subcultured to two blood agar plates, one of which is incubated in an anaerobic jar, and the other is incubated on a shelf in the incubator. After incubation, growth is observed on the plate from the anaerobic jar, but there is no growth on the plate incubated on the incubator shelf. Based on these results, how would this organism be categorized
Answer: obligate anaerobe
Explanation: This experiment established that a bacterial isolate is subcultured into same medium in two different plates, but one is placed in an aerobic condition (i.e., presence of oxygen) while the other in an anaerobic condition (i.e., absence of oxygen), and the result shows that there was no growth on the plate incubated on the incubator shelf, whereas there was growth on the plate conditioned anaerobically.
This simply translates that the bacterium does not need oxygen to grow i.e., It’s an anaerobe. Moreso, assuming it grows on the two plates we would say it's a facultative anaerobe.
Thus, since it growth was only established on the plate with anaerobic condition, it's an obligate anaerobic bacterium.

what is the female reproductive system cell
Answer:
Egg
Explanation:
Reproductive system is the system of an organism encompassed with the function of giving rise to new offsprings. In sexual reproduction, which involves two organisms, one of the organisms is usually a MALE while the other is a FEMALE.
In most sexually reproducing organisms, the female reproductive system undergoes a division called MEIOSIS to produce a sex cell or gamete called EGG CELL. This egg cell gets fertilized by the sperm cell produced by the male to form a zygote. Hence, EGG CELL is the female reproductive system cell.
Answer:
the egg
Explanation:

15. the image below shows chromosomes in a human cell
i need answer a, b and c please!
This representation called as karyotype, the gender of the individual is male and this individual have the correct number of chromosomes.
What are chromosomes?Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule.
Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure.
a component that can be found in a cell's nucleus. Proteins and DNA are arranged into genes on a chromosome. There are typically 23 pairs of chromosomes in each cell.
An individual's entire set of chromosomes is known as their karyotype. The phrase can also refer to an image created in a lab showing a person's chromosomes separated from one cell and organized in numerical order.
Present-day female humans have a single set of identical X chromosomes. Instead of a matched pair, male humans have one larger X and one smaller Y chromosome.
Thus, this image, known as a karyotype, shows that the person is male and has the appropriate amount of chromosomes.

Which of the following describes research that would be considered basic science? A. A professor at a university is observing the mating behavior of freshwater fish, B. A dairy farmer is designing a new machine for milking cows. c. Park rangers are trying to find out why a group of elm trees died. D. Doctors in a hospital are developing a new surgical technique.
Answer:
C. But be careful. This question is poorly conceived. Anything could be the answer.
Explanation:
A B and D are all specific to the disciple they are involved in.
That only lets you choose C. You could argue that a physicist or an electrical engineer would not be particularly interested in the death of some elm trees, and I think I would agree with you.
But what other choice to you have?
While the professor is tracking the fresh water fish, how is that benefiting mankind? What is he learning that is universally applicable. I wouldn't choose A.
B is an advance in technology. It might make the dairy farmer's life a whole lot easier, but I don't think it would have very effect on anyone else. Not B.
D: Again this benefits surgeons but again it is technology. I don't think it universally benefits all of humanity except those who are going to be operated on.
So I'll stick with C. People die. So do trees and all vegetation. I'd pick C, but I don't think there is a clear cut answer. Sometimes you get questions that you think the answer resides only in the head of the person writing the question. This is one of them.

Why is price discrimination not positive under perfect market conditions
Answer:
[u9gbvolgj;t9ug7yh
Explanation:
ft7odt8ugde86rfgef
Price discrimination is impossible in a market with perfect competition, and the average total cost (ATC) curve is identical to the marginal cost curve (MC).
What is price discrimination?Price discrimination is a sales strategy in which the seller charges different prices for the same item or service oriented on what the seller believes the customer will agree to.
In sheer price discrimination, the seller charges each customer the highest possible price.
Price discrimination occurs when various prices are charged to different customers.
This is not feasible in a perfectly competitive market because there are numerous firms competing for the price; however, it is possible in a monopoly because people have no other place to buy.
In a monopoly, price discrimination is the practice of charging different prices for a product.
Monopolies typically have greater control over providers than regular sellers, allowing them to significantly influence the selling prices of the suppliers.
Thus, due to this, price discrimination is not positive even under perfect market conditions .

The most muscular pump in the heart is the: *
septum
left atrium
left ventricle
right atrium
right ventricle
Answer:
The heart has four chambers and four main blood vessels that either bring blood to the heart, or carry blood away.
The four chambers are the right atrium and right ventricle and the left atrium and left ventricle. The blood vessels include the superior and inferior vena cava. These bring blood from the body to the right atrium. Next is the pulmonary artery that carries blood from the right ventricle to the lungs. The aorta is the body's largest artery. It carries oxygen-rich blood from the left ventricle to the rest of the body.
Beneath the tough fibrous coating of the heart, you can see it beating.
Inside the chambers are a series of one-way valves. These keep the blood flowing in one direction.
Dye injected into the superior vena cava, will pass through all the heart's chambers during one cardiac cycle.
Blood first enters the heart's right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle.
When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs.
In the lungs, the blood receives oxygen then leaves through the pulmonary veins. It returns to the heart and enters the left atrium.
From there, blood is forced through the mitral valve into the left ventricle. This is the muscular pump that sends blood out to the rest of the body.
When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta.
The aorta and its branches carries the blood to all the body's tissues.

How do mountains play a role in precipitation patterns?
a. As water vapor condenses,the air gets warmer b.it changes the amount of rain received c.it changes the direction of the wind d.as vapor condenses,it depends rain or snow on windward slopes
Answer:
a. As vapor condenses, it depends (specifically; leads to) rain or snow on the windward slope
Explanation:
The orographic effect which is the changes in masses of air as it moves along the mountain sides, up or down is the way the mountains have an effect on the climate
The orographic effect of mountains can be analyzed based on either the windward side, (which is the side that faces the incoming wind), or the leeward side (which is the opposite side of the mountain)
The moist and warm air from the oceans and other large water bodies are carried by wind onto the mountains where the moist wind is directed upward by the obstructing mountain wall.
As the elevation of the warm moist wind increases along the mountain, the cooler temperatures at the high altitudes forces the air to cool down, until the dew point is reached, which leads to precipitation of rain or snow.
