Answer:

DNA has a negative charge and is attracted by the positive side.

Explanation:

The DNA flows toward the positive side of the gel chamber because the positive side attracts DNA, which has a negative charge.

The hereditary substance in humans and virtually all other animals is DNA, or deoxyribonucleic acid.

In conclusion, This means that in the gel chamber the laws of attraction still apply.The law that state that unlike charges attract.

Hence,The positive side attracts DNA, which has a negative charge.

The resistance of a 7 mm-long axon can be calculated using the formula R = (ρ * L) / A, where R is the resistance, ρ is the resistivity, L is the length of the axon, and A is the cross-sectional area of the axon.

Given that the diameter of the axon is 10 µm, we can calculate the cross-sectional area using the formula A = π * r^2, where r is the radius of the axon.

First, we need to convert the diameter to radius by dividing it by 2. So, the radius of the axon is 5 µm or 5 × 10^-6 m.

Next, we calculate the cross-sectional area:
A = π * (5 × 10^-6)^2 = 3.14 * (5 × 10^-6)^2 = 3.14 * 25 × 10^-12 = 78.5 × 10^-12 m^2.

Now, we can calculate the resistance:
R = (0.5 ω · m * 7 × 10^-3 m) / (78.5 × 10^-12 m^2).

Simplifying the equation:
R = (0.5 * 7 × 10^-3) / (78.5 × 10^-12).

Calculating further:
R = 3.5 × 10^-3 / 78.5 × 10^-12.

Simplifying:
R = 4.44 × 10^8 ω.

Therefore, the resistance of a 7 mm-long axon is approximately 4.44 × 10^8 ω.

Sulfuric Acid (H2SO4) is a chemical compound made up of two hydrogen atoms, one sulfur, and four oxygen atoms.

The reason why H2SO4 carries only covalent bonds is because, in the structure, you have S-H bonds and S-O bonds one sulfur atom, and four oxygen atoms. Sulfuric acid is a powerful acid, soluble in water, very polar, and an outstanding solvent. Its applications involve the production of fertilizers and detergents. Sulfuric acid (H2SO4) is a strong acid with hygroscopic and oxidizing things. Sulfuric Acid is a mineral acid with the chemical formula H2SO4.

H2SO4 is an ionic compound but it has covalent bonds. Therefore from the above ending, we can easily conclude that Sulphuric acid has covalent bonds but it ionizes readily building it a very strong acid.

So we can conclude that Sulphuric acid holds covalent and co-ordinate bonds.

In conclusion, the ΔG at 37°C with a membrane potential of -50 mV (cytosol negative) is approximately 9649.25 J/mol.

To calculate ΔG at 37°C when the membrane potential is -50 mV (cytosol negative), we can use the Nernst equation and the equation for ΔG:
ΔG = -nFΔE
First, let's find the ΔE, the electrical potential difference across the membrane:
ΔE = (membrane potential outside - membrane potential inside)

= (-50 mV - 0 mV)

= -50 mV
Next, we need to convert ΔE to volts, as the unit of Faraday's constant (F) is in coulombs per mole of electrons. 1 mV is equal to 0.001 V, so:
ΔE = -50 mV x (0.001 V/1 mV)

= -0.05 V
Now, let's calculate ΔG using the Nernst equation:
ΔG = -nFΔE
Since we're calculating the change in free energy for the movement of Ca2+ ions, n

= 2 (the charge of a single Ca2+ ion) and F

= Faraday's constant (approximately 96485 C/mol):
ΔG = -(2)(96485 C/mol)(-0.05 V)

= 9649.25 C⋅V/mol
Finally, let's convert the units from coulombs times volts per mole to joules per mole using the conversion factor 1 J = 1 C⋅V:
ΔG = 9649.25 C⋅V/mol x (1 J/1 C⋅V)

= 9649.25 J/mol
Therefore, the ΔG at 37°C when the membrane potential is -50 mV (cytosol negative) is approximately 9649.25 J/mol.
In conclusion, the ΔG at 37°C with a membrane potential of -50 mV (cytosol negative) is approximately 9649.25 J/mol.

When two groups of organisms independently develop similar adaptations, we speak of convergent evolution. This type of evolution occurs when different species evolve similar traits or adaptations in response to similar environmental pressures or challenges.

Convergent evolution is a process in which organisms that are not closely related to each other independently evolve similar traits or adaptations to survive in similar environments or ecological niches. An example of convergent evolution is the development of wings in bats and birds, which are not closely related, but both evolved them in order to fly.

Convergent evolution is different from divergent evolution; it occurs when two or more closely related species develop different traits or adaptations in response to different environmental pressures or challenges. An example of divergent evolution is the development of different beak shapes in Galapagos finches, which evolved to allow them to exploit different food sources on the different islands they inhabit.

Each of these answers show a way that energy is used which is why there is less energy in the next trophic level than the first

Less energy is passed from one tropical level to another because energy is lost as heat to the environment. So the correct option is C.

The pyramid of energy describes how energy moves from one trophic level to the next in a food chain. The 10% law states that 90% of the energy that is gathered is wasted as heat in the original level and just 10% is left for the following level.

About 10% of the energy is used for metabolic processes at each trophic level, with the remaining energy being lost as heat to the environment. At each level, the chemical energy decreases but the overall system energy does not.

According to the 10% law, only 10% of energy is moved from a lower to a higher trophic level. Accordingly, only 10% of the energy that producers have conserved gets transmitted to herbivores.

Plants use the remaining 90% of this energy for a variety of functions, including breathing, growth, and reproduction.

The energy transmitted from herbivores to carnivores is also just 10% of the total. Therefore the correct option is C.
