Answer:
Stays the same.
Explanation:
Density = mass/volume
So if :
M/V = D
And if we were to double mass(M) and volume (V)
2M/2V = D
It will stay the same because the 2 and 2 would cancel out and we'd get the same density as the original value.
Which of these may be required to become a
nurse? Select all that apply.
doctoral program
two-year college
four-year college
certification
Answer:
What is required to become a nurse is two-year college or four-year college
and certification.
Explanation:
The nurses are in charge of the care of the patients and the administration of medicines, in addition to other activities that pursue the integral care of the sick person. To do this, nurses must receive training and demonstrate their ability to do the job.
Nursing training can be accomplished through various programs, including an associate's degree in nursing, a diploma, or a bachelor's degree, which can be completed in two, three, or four years, respectively.
After their studies, nurses must demonstrate their skills and knowledge in order to be certified —in addition to college— by institutions such as American Nurses Credentialing Center Certifications.
Doctoral program is a higher degree that requires more years of study and is not initially required to become a nurse.
1.Excess carbon dioxide is harmful to
the oceans because
A. they product carbonic acid form
the atmospheric carbon
B. it removes most of the dissolved
oxygen
C. it decreases the rate of evaporation
Increased levels of CO2 make the ocean more acidic and put sea organisms in danger. This could mean slower growth in the world's corals reefs, which are already stressed and dying from the warmer ocean temperatures associated with increased greenhouse gases in the atmosphere.
What are the causes and effects of ocean acidification?Ocean acidification is mainly driven by carbon dioxide gas in the climate dissolving into the sea.
This directs to a lowering of the water's pH, making the sea more acidic. Many factors contribute to rising carbon dioxide levels.
Thus, correct option is "A" they product carbonic acid form the atmospheric carbon.

Which major type of air mass typically brings cool, dry weather? maritime polar continental polar maritime tropical continental tropical
Answer:
b on eng 2020-2021
Explanation:
Air mass is defined as the volume of air that is determined by the temperature and water vapor content. The air mass is divided into four categories, which are maritime polar, continental polar, maritime tropical, and continental tropical.
The correct answer is:
Option B. continental polar
Continental polar air masses are generally cold and dry because they arise from the continental region. The air mass is stable and originates over Canada and Alaska. The continental polar are marked by the surface high pressure, cold temperatures, and low dew points.
The maritime tropical air mass is warm, moist, and unstable, whereas the continental tropical air mass is originated from the low-altitude desert and is characterized by negligible rainfall.
Therefore, option B is correct.

A.
Energy is stored in organic compounds during the process of cellular
respiration and then released during the process of photosynthesis.
B.
Energy is stored in organic compounds during the process of
photosynthesis and then released during the process of cellular
respiration.
C.
Photosynthesis and cellular respiration are both responsible for
storing energy in organic compounds and fermentation is responsible
for releasing that energy.
D.

while both photosynthesis and cellular respiration are responsible for
releasing that energy.
Answer:
The anwser is A! i am taking a test with the exact question!!! please mark brainliest
A
Energy is stored in organic compounds during the process of cellular respiration and then released during the process of photosynthesis. Thus, Option A is correct.
what are the factors affecting photosynthesis?It is a process by which autotrophic plant and bacteria use light energy as a source to make sugar from water and carbon dioxide.
They convert light energy into chemical energy which is stored in the form of starch.
The surface of Leaves have chloroplast which absorb light energy.
[tex]\rm 6\;CO_2\;+\;6\;H_2O\;\rightarrow\;C_6H_{12}O_6\;+\;6\;O_2\\\\[/tex]
Th factors affecting photosynthesis are the intensity of light energy increased then rate of photosynthesis also enhanced.
Higher concentration of carbon dioxide induces the rate of photosynthesis. The average range CO2 needed is from 300 – 400 PPM
The adequate temperature needed between 25° to 35° C and water is an important factor, the scarcity leads to refusal of stomatal opening to retain the amount of water.
Thus, Option A is correct.

Answer:
O Total energy in the system decreases as the ball
Explanation:
The statement which best describes the energy in this system is: A. The potential energy in the system is greatest at X.
What is potential energy?Potential energy can be defined as a form of energy that is possessed by an object due to its height (position or location) above a surface or planet Earth.
How to calculate potential energy.Mathematically, potential energy is given by this formula:
[tex]P.E = mgh[/tex]
Where:
m is the mass.h is the height.g is acceleration due to gravity.Since the height is maximum at point X, the potential energy in the system is greatest at X.

If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.
Which gender do you think is more affected by inheriting a mutated gene that causes red green colorblindness?
Answer:
The genes that can give you red-green color blindness are passed down on the X chromosome. Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother.

not all of the statement is correct. THE LACTIC ACID FERMENTATION IS ANAEROBIC not an aerobic.
The statements which are correct regarding cellular respiration are;
The final electron acceptor in the electron transport chain is oxygen.ATP are produced in Krebs cycle.As such, Two of the answer choices are correct.
Lactic acid fermentation is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells.The electron transport chain is one of the series of catabolic pathways of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism.The Krebs cycle takes place in the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). ... It is at this stage that NADH is converted into ATP.Read more:
