Why might countries with large oil reserves be interested in controlling the price and supply of oil?
Answers
Answer:
Explanation:
To make more money and to have a better economy as a country together
Answer: They want to make sure that there is a steady supply at a reasonable price so they can use the oil that they need.
Explanation:
As a cartel, the OPEC+ member countries collectively agree on how much oil to produce, which directly impacts the ready supply of crude oil in the global market at any given time. OPEC+ subsequently exerts considerable influence over the global market price of oil and, understandably, tends to keep it relatively high in order to maximize profitability.
If OPEC+ countries are unsatisfied with the price of oil, it is in their interests to cut the supply of oil so prices rise. However, no individual country actually wants to reduce supply, as this would mean reduced revenues. Ideally, they want the price of oil to rise while they increase supply so that revenues also rise. But that is not market dynamics. A pledge by OPEC+ to cut supply causes an immediate spike in the price of oil. Over time, the price reverts back to a level, usually lower, when supply is not meaningfully cut or demand adjusts.
Conversely, OPEC+ can decide to boost supply. For instance, on June 22, 2018, the cartel met in Vienna and announced that they would be increasing supply.3 A big reason for this was to offset the extremely low output by fellow OPEC+ member Venezuela.
Saudi Arabia and Russia, two of the largest oil exporters in the world who both have the ability to increase production, are big proponents of increasing supply as that would increase their revenues. However, other nations, who cannot ramp up production, either because they are operating at full capacity or are otherwise not allowed to, would be opposed to this.

Which term refers to a fertilized egg after the cells have begun to differentiate?
A. Blastocyst
B. Fetus
C. Embryo
D. Zygote
Answers
Answer:
D
Explanation:
Blastocyst refers to a fertilized egg after the cells have begun to differentiate. So, the correct option is A.
What is Blastocyst?A ball of cells known as a blastocyst develops in the first five to six days of pregnancy, shortly after a sperm fertilizes an egg. It embeds itself in the uterine wall, developing into an embryo and subsequently a fetes.
A healthily developed embryo will include six to ten cells three days following fertilizations. The fertilized egg develops into a blastocyst, a rapidly growing ball of cells, on the fifth or sixth day. The innermost collection of cells will develop into the embryo. The outer group will develop into the cells that support and safeguard it.
Within the first two weeks following conception, a developing, fertilized egg is known by a variety of names, include zygote, morula (day 4), or blastocyst (day 5). About 10 weeks after the previous menstrual cycle, or 8 weeks after conception, the embryonic period begins.
Therefore, the correct option is A.

7) Which star on the H-R diagram has a low surface temperature and the highest absolute brightness?
Explain how you arrived at that answer.
HURRY PLZZZ
Answers
The Hertzsprung-Russell diagram (commonly abbreviated as the H-R diagram) is a scatter plot of stars indicating the relationship between the absolute magnitudes or luminosities of the stars compared to their spectral ratings or effective temperatures. More simply, each star is plotted on the graph to measure its brightness compared to its temperature (color).
Hertzsprung-Russell diagram.
The diagram was created around 1910 by Ejnar Hertzsprung and Henry Norris Russell and represents an important step toward understanding stellar evolution or "the way stars go through sequences of radical and dynamic change over time."
It was made in 1905 by the astronomer Ejnar Hertzsprung and, independently, in 1913 by Henry Norris Russell. The Hertzsprung diagram showed the luminosity of stars as a function of their color, while the initial Russell diagram showed the luminosity as a function of spectral type. Both diagrams are equivalent.

If the eyepiece has an inscription of 12.5x. What is the total magnification of the microscope when she observed it under low power objective?
Answers
Answer: 10X
Explanation:
To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.
If the eyepiece has an inscription of 12.5x, then total magnification under low power could be 125x as the magnification under objective lens could be 10x.
What is the magnification of a microscope?
A simple microscope or magnifying glass can produce an image of the object. The object is focused upon by the microscope or the magnifying glass. There are simple magnifier lenses that are bi-convex, which means that they are thick at the center compared to at the periphery.
The intermediate plane of the image is normally located about 10 millimeters below the top of the body tube of the microscope. It is at a specific location. This location is within the fixed internal diaphragm of the eyepiece.
Between the back focal plane of the objective and the intermediate image, there is a distance which is termed the optical tube length. The value is different from the mechanical tube length of a microscope. It is the distance between the nosepiece, where the objective lens is attached, and the top portion of the observation tubes. Here the eyepiece lens is inserted.
Therefore, if the eyepiece has an inscription of 12.5x, then total magnification under low power could be 125x as the magnification under objective lens could be 10x.

Number of mitochondria is constant is not the characteristic of mitochondria. So, the correct option is (D).
What is Mitochondria?
Mitochondria are defined as membrane-bound organelles present in the cytoplasm of all eukaryotic cells where they are responsible for the production of adenosine triphosphate (ATP), the main energy currency of the cell.
The primary function is to produce energy through the process of oxidative phosphorylation which is responsible for regulating the metabolic activity of the cell and promotes cell multiplication and cell growth. Mitochondria also detoxify ammonia in liver cells where it plays an important role in apoptosis or programmed cell death.
Thus, number of mitochondria is constant is not the characteristic of mitochondria. So, the correct option is (D).

different temperatures: 10° C and 25° C.
The student proceeded to set up two electronic water baths: a warm water bath (25° C) and a
cold water bath (10°C). She also set up four respirometers: two containing germinating peas
and two containing non-germinating peas. Where would she need to place the respirometers in
terms of water baths to ensure that she was setting up a controlled experiment?
