Answer:
2.4 × 10⁻⁶ M
Explanation:
Molar concentration = no of moles of solute (enzymes)/volume of solvent(cystosol)
Let V = volume of solvent = volume of cystosol = πd²h/4 where d = diameter of cell = 1.0 m and h = height of cell = 2.0 m
Concentration of enzymes, C = n/V where n = no of moles of enzymes
Also, n = m/M where m = mass of all enzymes and M = molecular weight of protein = 100,000
Note that the solvent for the enzymes is cystosol, since they are dissolved in it.
Density of cystosol,ρ = specific gravity of cystosol in g/cm³ = 1.20 g/cm³.
Now, ρ = m'/V where m = mass of cystosol and V = volume of cystosol
m' = ρV
m' = 1.20V
Given that 20 % of the cystosol is protein and all protein are enzymes, the mass of enzymes is thus m = 0.2m' = 0.2 × 1.20V = 0.24V
C = n/V
= m/MV
= 0.24V/100000V
= 2.4 × 10⁻⁶ mol/cm³
= 2.4 × 10⁻³ mol/dm³
= 2.4 × 10⁻³ M
This is the concentration of all the 1000 enzymes.
So, the concentration of one enzyme is 2.4 × 10⁻³/1000 M = 2.4 × 10⁻⁶ M
Determine the rate of oxygen consumption at each temperature for comparison. Then divide the higher rate by the lower rate to obtain the difference (ratio) between the two temperatures. Round your answer to the nearest 0.1. It can be concluded that mouse respiratory rate (increases or decreases) when temperature is lowered. In this experiment there was a fold difference in respiratory rate at the two temperatures.
Answer:
In mice rate of respiration increases as the temperature drops.
Explanation:
As the temperature decreases, the respiration rate also decrease because the body needs less oxygen for the production of energy. But in the case of mice, the rate of respiration decreases and the reason is the fear. Results showed that the respiration increased in mice as the decrease in temperature occur, caused due to the fear instilled in the mice towards cold temperature so in mice rate of respiration increases as the temperature drops.

What is the direction of energy flow in an energy pyramid? How much energy is transfered from one step to another?
Answer:
- The flow of energy is from the lowest level (i.e., the base of the pyramid) to highest levels
- Approximately 10 percent
Explanation:
The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. Each trophic level is characterized by organisms that play specific roles in an ecosystem, for example, photosynthetic organisms (producers) at the base of the pyramid which represent the source of energy for herbivores localized at a higher level. The amount of energy decreases as it moves to higher trophic levels, approximately 10 percent of the energy is transferred from a trophic level to the next level and the remaining energy is lost as heat.

Answer:
Climate change leads to: A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease.
Explanation:

Can anyone help me with my homework
Answer:
Explanation: 1. Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.
2. Organic, Clastic and Chemical Sedimentary Rocks.
3. The formation of coal takes millions of years, which is why it is an exhaustible and non-renewable natural resource.
It was formed around 300 million years ago when the earth was covered with swampy forests.
When plants in these forests- mainly trees, mosses, ferns, and reeds died, they fell into the swamps.
Thus there was a thick layer of dead vegetation in the swamp formed.
4. Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering.
6.Squeezed and compressed over time, the sediments become 'consolidated' (made solid) into layers of rock. Stratigraphy is the study of those layers Cementation occurs when dissolved mineral components deposit in the interstices of sediments. It is the sticking together of sediment that forms a rock.
7. It is used by marine biota to form a shell frame. Shells of marine animals are rich in carbonate minerals. When the marine animals die, the shells will accumulate and settle in a place so that rocks are formed.
8. This may be due to the overburden load, which is essentially the weight of all the material above the layer of minerals in question squashing them flat. Or it may be due to deformation caused by the movements of tectonic plates which often causes a form of deformation known as shearing where two things slide past each other. When this occurs in ductile rock masses, it acts to flatten and rotate mineral grains so that their long axis is parallel to the shear plane.

If u looked at a SA cells and cardiac muscle cells under a microscope, do u think they would look the same or different from each other? Explain ur reasoning HELP MEE PLSSSSS
Answer:
They look a little bit different. SA cells contain fewer mitochondria, fewer myofibers, and a smaller sarcoplasmic reticulum. This means that the SA node cells are less equipped to contract compared to the atrial and ventricular cells.
What would happen to Earth's climate if we had no moon, and why?
Answer:
The tilt creates what we know as seasons and changing weather. Without the pull of the moon, this tilt would change.
Explanation:
Either the tilt would become extreme, leading to extreme and severe seasons, or the tilt would decrease, and we would see almost no seasons at all. The moon influences life as we know it on Earth.
Answer: Because It is the pull of the Moon's gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).
The tilt creates what we know as seasons and changing weather. Without the pull of the moon, this tilt would change.

How are the smallest ocean waves produced?
Answer:
Ocean waves are usually formed by a distant wind. ... The area which the wind affects the surface is called the fetch. The larger the fetch, the greater the waves produced. the small waves generated by storm winds are often confused and disorganized.
Explanation:
Answer:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

Which protein is damaged at the nerve endings during mercury toxicity
a. keratin
b. tubulin
c. pilin
Answer:
b. tubulin
Explanation:
Tubulin is a superfamily of proteins that make up microtubules who have many functions including intracellular trasport of neuron's vescicles
Tubulin protein is damaged at the nerve endings during mercury toxicity.
What do you mean by Mercury Toxicity?Mercury toxicity occurs when an individual is highly exposed to mercury.
The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs, and kidneys, and may be fatal. This is considered as one of the severe toxicity that a person suffers.
Tubulin proteins are a very important class of proteins that helps in the formation of microtubules that have numerous functions in our body including the cytoskeletal arrangement of cells, intracellular transport of neuronal vesicles. And when a person suffers from mercury toxicity, such proteins are damaged and result in improper conduction of nerve impulses.
Therefore, Tubulin protein is damaged at the nerve endings during mercury toxicity.
