Explanation:
how does the brightness/luminosity change throughout the cycle of a massive star?
Answer:As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.
Explanation:
Answer:
Brightness-Luminosity Relationship:
At a particular Luminosity, the more distant an object is, the fainter its apparent brightness becomes as the square of the distance

Other organisms were another factor. What kinds of changes in other populations of organisms could be affecting the moths?
The presence of the industrial revolution caused moths to evolve, as different colored moths became dominant in certain phases of climatic changes, such as the black moth, which gained advantage during the industrial revolution.
What is the significance of the evolution of moths?In moths, evolution occurred as a result of changes in climatic conditions, such as before the Industrial Revolution, when the environment was clean, giving light-colored moths an advantage over the predator-favored black moth. The environment became darker after the industrial revolution as a result of smoke, which favored dark moths.
Hence, the presence of the industrial revolution caused moths to evolve, as different colored moths became dominant in certain phases of climatic changes, such as the black moth, which gained advantage during the industrial revolution.

Petroleum is a natural resource that is found below the surface of the Earth. Petroleum is unevenly distributed on Earth, but it is most often found in petroleum traps, which are underground rock formations that block the movement of petroleum.
Which of the following best describes what must have happened in the past in an area with a large petroleum trap?
A.
Permeable underground rock formations must have allowed the movement of organic matter deep into the Earth. Then, the organic matter must have been exposed to freezing temperatures until it formed petroleum.
B.
Impermeable underground rock formations must have blocked the movement of organic matter through the Earth's surface. Then, the organic matter must have decomposed to form petroleum inside the rock formations.
C.
Organic matter must have been exposed to intensely cold temperatures until it became petroleum. Then, the petroleum must have moved up to the Earth's surface through permeable underground rock formations.
D.
Organic matter must have been buried and placed under intense heat and pressure until it became petroleum. Then, the petroleum must have collected inside an impermeable underground rock formation.
Answer:
The answer is D.
Explanation:
Remember heat and pressure.
The statement that best describes an action that has happened in the past in an area with a large petroleum trap is as follows:
Organic matter must have been buried and placed under intense heat and pressure until it became petroleum. Then, the petroleum must have collected inside an impermeable underground rock formation.Thus, the correct option for this question is D.
What is the Petroleum trap?The petroleum trap may be defined as a methodology that deals with the subterranean rock formation that considerably restricts the migration of petroleum and its components and causes it to accumulate in a reservoir that can be exploited.
Petroleum, crude oil, etc. are formed from the organic matter that has been buried millions of years ago. These organic matter are placed under intense heat and pressure in order to form components like petroleum. These formed components are then collected inside an impermeable underground rock formation.
Therefore, the correct option for this question is D.

Why do you think mapping the bedbug genome may help scientists control pests?
Explanation:
When mapping the genome, it shows where other pests are more likely to appear. This means more control over the rate of pest growth, and they can stop reproduction from increasing.
Understanding the genome will enable scientists to know what traits the bug has and whether they have any resistance to insecticides. The bugs may have natural resistance to certain insecticides, but not to others. This research may help scientists develop effective insecticides.

What might happened if we continue burning fossil fuels at the rate we do today ?
Choose the best answer
A. The cost of fossil fuels may drop
B. Fewer and fewer oil wells and coal mines may be constructed
C. The earth’s climate may change rapidly
D. Automobiles will become less fuel-efficient
Answer:
A
Explanation:
because when we use more fossil fuel new oil well will be discovered and due to this the fuel value will became drop down.
We will continue to see rising global temperatures and climate change if the world does not reduce the levels of carbon dioxide emitted by burning fossil fuels. Thus, option A is correct.
What are the consequences of burning fossil fuels?Carbon emissions will stay high as long as the world depends on fossil fuels for both energy production and transportation.
It is obvious that reversing man-made climate change is generally better as stopping it when its impacts become more severe.
Even while warming would undoubtedly slow if we stopped using fossil fuels right away, greenhouse gas removal from the atmosphere will eventually be necessary.
Therefore, because as we utilize more fossil fuels, new oil wells will be found, which will lower the price of fuel.

Explanation:
Answer: It’s A
Explanation:
It you hold the cube in your hand it will melt because of the body heat. If you break the pieces and warm them up, it will melt. If you put it in a glass of room temperature water, the water would absorb the cold and it will melt. But if you put it in an insulated container, it will keep the cold in hence it will not melt the fast.

and produce unspecified cells. They can be developed into a required tissue because of their ability of
.
Answer:
Stem cells have the ability to divide through mitosis and produce unspecified cells. Stem cells can be developed into a required tissue because of their ability of differentiation.
Explanation:
A stem cell is a cell that is in an undifferentiated state. This means that it has not specialized in a specific type that carries out a specific function of that tissue, which does not imply that stem cells do not have their own function. The concept of stem cell is due to the ability to originate specialized cells from one or more tissues, depending on the degree of potency or plasticity it has. They are found in all multicellular living organisms. Their main characteristic is that by reproducing through the process of mitosis (they divide into two cells) they can form more stem cells or differentiate, that is, they become specialized cells, in such a way that they are essential for the renewal of cells in different tissues. and to repair them.
Stem cells have the ability to divide through mitosis and produce unspecified cells. They can be developed into a required tissue because of their ability of differentiation.
Stem cells are a special type of cell that may develop into a variety of specialized cells inside the body. They have the ability to differentiate into more specialized cells through the process of mitotic activity (mitosis) and perform restorative and regenerative roles.
Stem cells have significant and potential treatment for a variety of diseases due to their capacity to repair, regenerate, and grow into certain specialized cell types.

Answer:
The statement is true because there is more of the actual atom hydrogen in living organisms, as oxygen is more abundant in the world, but not in every living organism.
Explanation:
For example, there is more hydrogen in living organisms added up, but there is more oxygen in the world. If you add them all up, the mass of oxygen would be more then hydrgen, but more hydrogen in actual living organisms.
