I'm giving Brainilest if you answer this and some points and 5 stars and a Thanks: Describe the positions of high and low pressure and the temperature of the land and water to explain how land breezes form.
Answer:
A high pressure system works downwards and brings with it good weather, while a low pressure system works upwards and brings bad weather. Due to the Earth’s rotation and friction on its surface, air currents are formed. When these currents move clockwise and out of the center, a space is formed at the center. The land quickly loses its heat whiles the water retains its warmth. That means the air over the water is warmer, less dense, and begins to rise. Low pressure is created over the water. Cold and dense air over the land begins to move to the water surface to replace the warmer rising air. The cool breeze from the land is called a land breeze.

What is the pH of a neutral solution?
A. 4
B. 3
C. 7
D. 14
Answer:
It would be C. 7
Explanation:
These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution. All other substances are compared to this neutral point. Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic.\

Behavioral responses in organisms require communication between an organism and its environment (option C).
Explanation:
The behavior of an organism depends on the function of relationship with the environment that surrounds it, and the way to respond to the diverse stimuli that are in this environment.
Behavioral responses always occur as a result of the interaction between the physical environment and other living organisms. This interaction triggers a series of stimuli that are perceived by the senses and processed by each organism, developing an appropriate response to each of them.

Recently, a human trachea ( a respiratory organ) was produced by using a patient's own stem cells. The benefit of using the patients own cells to produce a trachea instead of receiving one from a donor is that (1) there will be more enzymes produced to help maintain homeostasis in the trachea (2) there will be an increase in the quantity of antibodies that the patient produces in (3) there is less of a chance that the patients immune system will attack the trachea (4) response to the new trachea
Answer:
3
Explanation:
The benefit of using the patients own cells to produce a trachea instead of receiving one from a donor is that there is less of a chance that the patients immune system will attack the trachea. The correct option is 3.
What are stem cells?Stem cells are the building blocks from which all other cells with specific roles are derived in the body. Daughter cells are created when stem cells divide properly in the body or a lab to create more cells.
Embryos and adult bodily tissues are the two main sources of stem cells. Researchers are also experimenting with genetic "reprogramming" methods to create stem cells from different types of cells.
Instead of receiving a trachea from a donor, using the patient's own cells to create one has the advantage of decreasing the likelihood that the patient's immune system will attack the trachea.
Thus, the correct option is 3.

Hope this helps!!! :)
The experimental group is the bushes of roses that got the fertilizer.
What are experimental groups?
In a scientific experiment, the group on which the experimental process is carried out is referred to as the experimental group. For each group, the independent variable is altered, and the result, or change, in the dependent variable is noted.
The control group, in contrast, is the one that does not get the therapy or in which the independent variable is maintained constant. To have enough data to properly ensure that the relationship between the independent and dependent variable is not the result of chance, experimental and control groups must be present.
You can only be reasonably confident in the results of an experiment if you use one subject (with and without treatment) or one experimental subject and one control subject.
Therefore, The experimental group is the bushes of roses that got the fertilizer.

In what phase of mitosis does
the nuclear membrane reform
around the nucleus?
A. prophase
B. anaphase
C. telophase
Answer:
your answer is c
Explanation:
telophase
Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.
hope this help
Answer:
Telophase since that's the stage when the splitted chromosomes are being enclosed to form the dna inside of nucleus, which requires the nucleus membrane to form.
prophase is when nuclear membrane breaks to get the chromosomes ready for metaphase.
anaphase is when chromosomes are pulled apart.

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.

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.
