Answer:
I believe the answer is sugars.
Explanation:
A characteristic of sugars is that they do not separate in water. Sugars is the only answer in the options that makes since because you can dissolve sugar in water, however, you can't separate the sugars in water.
There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiply the series of dilutions together to find the final dilution value. If 6 serial dilutions are performed, each with a dilution of 0.1, what is the cumulative dilution
Answer:
cumulative dilution = 0.000001
Explanation:
A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.
The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:
Cumulative dilution = (F)ⁿ
where:
F = dilution factor = 0.1
n = number of serial dilutions = 6
∴ cumulative dilution = (0.1)⁶ = 0.000001
explain the advantage of the synaptic cleft being so small
Answer:
The size of the synaptic cleft is small which results in the neurotransmitters to pile up over time thus making the neurotransmitters' concentration increase and therefore can proceed with their function of sending nerve impulses. Hope that helped!

?Which form of energy is NOT correctly associated with the related example
kinetic energy: fat molecules O
potential energy: water held behind a dam o
kinetic energy: movement of muscles
chemical energy: glucose o
Answer:
kinetic energy: fat molecules
Explanation:
Fats store energy so it would be potential.
Kinetic energy: fat molecules
Kinetic energy is the energy that an object or particle uses during its motion. Potential energy is the stored form of energy already present in the object or particle. Chemical energy is the energy stored in the bonds of chemical substances. Water held behind the dam will have potential energy the water currents store energy within them which can be used to move the turbine in the water dam to produce electrical energy. Movement of muscles during walking, running, or performing any other activity which can be seen in the form of displacement from one region to another is due to kinetic energy. Glucose is a chemical molecule whose bonds when broken releases energy in the form of ATP or adenosine triphosphate which is a chemical energy. Fat molecules store energy in the adipocytes in the form of potential energy not kinetic energy. Hence, option kinetic energy: fat molecule is incorrect.Learn more about kinetic energy:

How do limited abiotic resources impact the overall biotic organisms in an ecosystem?
Answer: Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. ... Limiting factors keep populations within an ecosystem at a certain level. They may also limit the types of organisms that inhabit that ecosystem.
Explanation:
How is cellular respiration and photosynthesis linked to specific organelles within the eukaryotic cells?
Answer:
Respiration. The energy collected in the chloroplasts is used during cellular respiration. ... The carbon dioxide and water produced are transferred back to the chloroplast where they are again used for photosynthesis. Cellular respiration takes place in another organelle called the mitochondria.
Explanation:
The mitochondria and cytoplasm is responsible for cellular respiration and the chloroplast is responsible for pjotosynthesis. Scientists theorize that mitochondria were once bateria themselves since they have their own Dna. They incorporated themselves into our cells to help us make energy. The chloroplast uses sunlight to break the hydrogen off the water and use the hydrogen to transfer electrons.

What is the wavelength of an X-ray whose frequency is 2.0 × 1018 Hz? Hint: An X-ray is an electromagnetic wave, so its velocity is equal to the speed of light (3.0 × 108 m/s).
A.
1.5 × 10-10 m
B.
3.0 × 10-8 m
C.
6.0 × 10-9 m
D.
0.6 × 10-11 m
Answer:
A. 1.5 × 10-10 m
Explanation:
Given the following data;
Frequency = 2.0 × 10^18 Hertz.
Speed of light = 3.0 × 10^8 m/s
To find the wavelength;
Wavelength = speed/frequency
Substituting into the equation, we have;
Wavelength = 3.0 × 10^8/2.0 × 10^18
Wavelength = 1.5 × 10-10 meters.
Sequence of dna that is not involved in coding for a protein
Answer:
Transfer RNA, Ribosomal RNA, and Regulatory RNAs
Explanation:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules.
Answer: Ribosomal RNA, Transfer RNA, and Regulatory RNAs.
Explanation: The introns do not code for any protein and are removed from the mRNA before it is made into protein.
