The answer is True , Gene therapy attempts to treat illness or strengthen your body's resistance to illness by replacing a damaged gene or adding a new gene.
Numerous disorders, including cancer, cystic fibrosis, heart disease, diabetes, hemophilia, and AIDS, may be treated by gene therapy.
With gene therapy, medical professionals provide bodily cells a healthy copy of a gene. This healthy gene may introduce a brand-new gene,
inactivate a damaged (mutated) gene, or take the place of an existing gene. These beneficial genes enter cells via carriers, or vectors.
Gene therapy is a method for treating or curing disease by changing a person's DNA. Gene treatments can function in a variety of ways: putting a healthy copy of the gene in place of a disease-causing gene.

complete the following sentence correctly. the membrane of a neuron contains many more __________ leak channels than __________ leak channels, and this causes the resting membrane potential to be somewhat near to the equilibrium potential for __________.
The membrane of a neuron contains many more __K+__ leak channels than ____Na+___ leak channels, and this causes the resting membrane potential to be somewhat near to the equilibrium potential for __-70mV___.
What is leak channel ?
Ion channels that are non-gated are always open. These channels are also known as "leak" channels since they do not impose any resistance on the ions as they move through them.
The simplest ion channel type is a leakage channel since its permeability is essentially constant. Potassium and chloride channels are the leaky channel types that are most important in neurons.
In order to generate electrical impulses in neurons, potassium (K(+)) channels, which are membrane proteins, allow rapid and selective flow of K(+) ions across the cell membrane. K(+) channels are therefore essential for controlling neuronal excitability.

What happens when you burn hydrocarbon fuels?
Hydrocarbon fuels can undergo complete combustion or incomplete combustion depending upon the amount of oxygen available.
Complete combustion happens when there is enough air present. Carbon and hydrogen atoms in hydrocarbon fuel combine with oxygen in an exothermic process, producing carbon dioxide and water while emitting energy.
Incomplete combustion occurs when the supply of air or oxygen is inadequate. Water is still generated, but so are carbon monoxide and carbon. There is less energy released than in full combustion.
For example, here is one potential equation for incomplete propane combustion: carbon + carbon monoxide + water = propane + oxygen

A block attached to a spring is oscillating with an amplitude of 10cm. What will be the block's amplitude if its total energy is quadrupled?.
A block attached to a spring is oscillating with an amplitude of 10 cm. If its total energy is quadrupled, the amplitude of the resulted periodic motion becomes 16 times.
The position of the block over time is given by the equation:
x(t) = A cos(ωt + ∅)
Where
A = amplitude
ω = angular frequency
∅ = phase
The total energy of the oscillation or periodic motion is stored as the potential energy:
E = 1/2 x kA²
Where k is the spring stiffness.
Hence, the total energy is directly proportional to the square of the amplitude.
E ∝ A²
Which means, if energy is doubled, the resulted amplitude of the periodic motion is 2² of quadrupled.
Similarly, if the total energy is quadrupled, the amplitude will be 4² times or 16 times.

What would happen if complexes i-iv of the mitochondrial electron transport chain pumped protons in the opposite direction?
If complexes i-iv of the mitochondrial electron transport chain pumped protons in the opposite direction There wouldn't be any ATP production.
The electron transport chain's complexes I through IV force protons out of the mitochondrial matrix and into the intermembrane space. This is how the electrons go downward, helping to create the ATP molecules.
If the complexes pumped or transported the electron upward or against the gradient, there would be no proton and electron exchange and no ATP synthesis.
The majority of ATP is created during oxidative phosphorylation in mitochondria, specifically through the action of an electron transport chain (ETC) in the inner mitochondrial membrane. A little quantity of ATP is produced during respiration as a result of glycolysis in the cytoplasm.
