Answer:
A Carbon Dioxide ( CO2)
Explanation:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.

Why is the intensity of a pulse different at different sites?
Answer:
Because pulse wave velocity decreases as arterial diameter decreases, a slight difference in local vasculature can cause inter-site differences not only in pulse transit time but also in its variations.

Is better for an ecosystem to have high or low species abundance?
Answer:
There should equilibrium state in the ecosystem in case of number of species, if there will be high species abundance there would be higher rate of competition in between the species also the predation can be easily seen in such ecosystem. On the other hand if the species abundance is low then the competition between the species and predation can not be seen.Select the correct answer from each drop-down menu.
A researcher conducts an experiment on the secretion of a particular hormone in mice. Scientists inject mice with a substance that
stimulates the production of the hormone. The scientists then test the levels of hormones produced by the mice. The tool used to
measure the hormones consistently detects the levels at 10 points lower than the a (
Answer:
The correct answer is - accurate.
Explanation:
Systematic measurement errors take place when there is a consistent inaccuracy found in the result of the measurement. In the given case here is consistent 10 points lower than the actual value of hormones produced in the mice. the tool that is measuring the level of the hormones in the mice is showing systematic error and measurements are not accurate.
Thus, the correct answer is - accurate.

Students in Mr. Painter's science class studied samples of pond water using a microscope. To prepare for the experiment, the students placed a drop of pond water on each microscope slide, and then covered the drop with a cover slip that was marked with a 1 mm grid. Using the microscope to view the slides, students counted how many of each type of organism they found in each 1 mm square. Finally, each student calculated the total number of each type of organisms. Their data is shown below. Which organism is the least plentiful in the pond water studied? A. amoeba B. volvox C. euglena D. paramecium
Answer:
Euglena
Explanation:
the least plentiful organism in the pond water studied. Each student found fewer euglena than any other organism.

What happens to air pressure as the altitude increases?
O It gets lower
o It gets higher
0 It stays the same
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

Which statement best describes the function of nucleic acids?
A. Stores genetic information and helps to make proteins
B. Increases the rate of chemical reactions
C. Stimulates metabolism in all body cells
D
Activates secretion of the body's hormones
Answer:
A. stores genetic info and helps make proteins.
Explanation:
Nucleic acids are DNA and RNA.
The statement that best describes the function of nucleic acid is stored genetic information and helps to make proteins. The correct option is A.
What is nucleic acid?Nucleic acid is a macromolecule. Nucleic acid is made up of nucleotides. The composition of nucleotides is a 5-carbon sugar, a phosphate group, and a nitrogenous base.
Nucleic acid is the main component of the genetic material of the living organism. They are DNA and RNA. DNA is the main genetic material of animals and plants, and RNA is found in some bacteria and some plants.
DNA and RNA store the genetic information of the organism. As this, nucleic acid also contains genetic material. This genetic information is used in synthesizing proteins.
Thus, the correct option is A. Stores genetic information and helps to make proteins.

It takes place when magma introduces
great amount of heat into an existing rock
resulting in the recrystallization and mineral
reaction in the rock.
Answer:
The correct answer is - contact metamorphism.
Explanation:
Contact metamorphism is one of the two metamorphism processes which takes place when the pre-existing rock is introduced to a great amount of heat which affects it by an intrusion of magma. It is known as a low pressurized, high-temperature type of metamorphism.
An example of this type of metamorphism which experiences recrystallization in the rock and forms a metamorphic marble that is formed by the recrystallization and mineral reaction of the limestone.
