Answer:
C
Explanation:
It controls muscle contraction
Answer:
C
Explanation:
Breathing pretty much requires complex interactions of central nervous system with the respiratory system. Therefore as you breathe muscle contraction occurs making the nervous system and respiratory system work hand in hand.
hope this makes sense.

Write down the functions of
1.microtubules
2.tripletsof microtubules
Answer:
Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility
Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.
Hope it helps :)
Answer:
Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).
triplet microtubules are linked together to make the walls of the cylinder.

Which of the following can be inferred from the genetic code?
A.All organisms have a common biochemical evolutionary origin.
B.Organisms can live without genetic code.
C.Four nucleotides.
D.Four nucleosides.
Answer:
A. All organisms have a common biochemical evolutionary origin.
Explanation:
Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.
One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.

define the term (1)semi-permeable membrane (2) osmosis tell the answer i will mark u as brainlist
Answer:
a)the outermost part of an animal cell that selectively allows things to pass through and come out.
b) the passing of water molecules from higher conc. to lower conc.
Answer:
(a) Semi-permeable membrane:
A semipermeable membrane is a membrane that only allows the movement of solvent molecules but restricts the movement of solute particles across the membrane.
(b) Osmosis:
The process of movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane is called osmosis.
When two nearby concentrations are different, materials will tend to spread out to equalize the concentration. For example, if you put a drop of food colouring in some water it will gradually spread through the whole water.

Which of the following best describes the difference between a cation and an anion?
Answer:
An anion is a negatively charged ion that has gained more electrons than protons and added them to it's energy levels. A cation is a positively charged ion that has lost electrons from it's energy levels. It also has more protons than neutrons.
Explanation:
Advocates for organic farming claim that their methods result in a number of benefits to farmers, consumers, and the environment. Scientists now plan to study the claims that organic farming advocates make by developing testable hypotheses about the economic and environmental benefits of growing organic foods. The scientists plan to collect data from farmers and other producers. Which hypothesis should the scientists use
Answer:
''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.''
Explanation:
The hypothesis i.e. ''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.'' This hypothesis can be tested by the scientists by taking two fields in different location having same environmental conditions. One field they apply conventional farming whereas other field apply only organic materials and no chemicals. We can see that the cost on expensive fertilizers, pesticides and weedicides can't used in organic farming so it is economically benefitted to the farmers as well as no pollution occurs which happens due to the use of chemicals. Moreover, the price of organic food is 3 times higher due to its non-hazardous nature.

He has 3 groups of test subjects. The 1st group of dogs
water. The 2nd group of dogs receives 10 mg of caffeine each, and the 3rd group receives 50 mg of caffeine each.
measure their activity levels
by recording how long each dog runs without stopping,
He will
in this experiment?
after giving them the pills. What is the dependent variable
Answer:
How long the dog runs without stopping
Explanation:
The dependent or responding variable in an experiment is the variable that is dependent on the changes made to the independent variable. It is also the variable that is measured or recorded in an experiment.
In this experiment where a student tests the effect of caffeine on dogs. Three groups of dogs were used for the test and they received water, 10mg caffeine and 50mg caffeine respectively. The different level of caffeine used is tested by recording how long each dog runs without stopping. Hence, how long the dog runs without stopping is the DEPENDENT VARIABLE.
Explain How a chloroplast helps a cell get the meterials it needs
Answer:
chloroplasts work to convert light energy of the sun into sugars that can be used by cells. Its like a solar panel that changes sunlight energy into electric energy. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast.

If your body lacks enzymes that break down carbohydrates, it would be unable to get __A__ for energy production. If you lacked the enzyme to digest proteins, you may not absorb enough __B__.
Answer:
Glucose and amino acid.
Explanation:
If your body lacks enzymes that break down carbohydrates, it would be unable to get glucose for energy production while on the other hand, if you lacked the enzyme to digest proteins, you may not absorb enough amino acid that our body needs for the formation of muscles. Enzymes play a great role in the breakdown of macro food particles into simpler molecules so that it can be absorbed by the cells.
Answer:
A: Sugar Molecules
B: Amino Acids

Why people get cholera in our community
Answer:
Search Results
Featured snippet from the web
A person can get cholera by drinking water or eating food contaminated with cholera bacteria. In an epidemic, the source of the contamination is usually the feces of an infected person that contaminates water or food. The disease can spread rapidly in areas with inadequate treatment of sewage and drinking water.
Explanation:
The mode of transmission of Cholera is through fecal contamination of food or water. Transmission is therefore closely associated to poor environmental management due water and sanitation issues

Answer:
The correct answer is - d. the idea that substances can produce germs on their own.
Explanation:
Spontaneous generation is an obsolete theory or idea that supports the production of living things and substances from non-living substances and things.
This purpose is that the living creatures could arise from nonliving matter. In microbiology, it is an idea that says that substances can produce germs on their own even if the substances are not similar.

The diagram below shows a light ray striking Medium A and Medium B at the same angle. (4 points)
A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.
Which statement is correct?
The speed of the light ray is the same in air and Medium A.
The speed of the light ray is the same in air and Medium B.
Medium A and Medium B have different densities because light refracts at different angles.
Medium A and Medium B have the same density because the light ray strikes both at the same angle.
Answer:
A the speed of the light ray is the same in air and medium
