The mitochondrion, like the nucleus, has two or more membrane layers. How is the innermost of these layers different from that o
tensa zangetsu [6.8K]

Answer:

The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature  to increase the surface area for reactions (electrochemical  gradient) by accommodating protons pumped into it by the proton motive force(PMF)  from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.

Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.

Inversion of DNA sequences within chromosomes is a common process in evolution. The following gene arrangements in a particular
Maksim231197 [3]

Answer:

The correct answer is "Fist sequence; Fourth sequence; Second sequence; Third sequence".

Explanation:

Inversion of DNA is a process that often occurs during evolution of chromosomes. It occurs when the breakage of a chromosome in two places, results in the reinsertion of a DNA but in a reversed fashion. The evolutionary order of predecessors of inversion of DNA can be established by looking on the number of nucleotides that are different in the sequences of DNA. In this case, the first sequence is the ancestor and it haves the sequence "ABCDEF". The second in the evolutionary order is the fourth sequence since it originates from the first sequence only by changing the "BC" nucleotides to the end of the sequence "ADEFBC". The third in the evolutionary order is the second sequence since it still starts in AB, but has the other four nucleotides different: "ABFEDC". The last in the evolutionary order is the third sequence, which is completely different and reversed respect to the first sequence: "FEDABC".

A certain machine can output 50 Joules (J) of energy when 100 J of energy are input. If the amount of friction experienced by th
Makovka662 [10]

Explanation:

75 J

Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.

With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

Genotype. A human being's genome is made up of approximately 3 billion base pairs which make up about 2000 genes. Individuals, however, differ slightly in the sequence of their DNA in some regions. This unique genome identity is the indivudual genotype. Sequence of DNA in a genome can nowadays be determined through sequencing using Next Generation Sequencing machines

Pros and cons of canopy fogging
pishuonlain [190]

Pros:

It is (mostly) based on pyrethrine spray which kills the insects rapidly.

It not poisonous to other animals.

It uses synthetic, natural spray which is safe to use because it breaks down within 10 minutes.

Te technique can reach tall forests.

It can be used in closed spaces ( greenhouses, basements etc).

 

Cons:

It requires windless circumstances ( which is mostly at nights).

Breathing fog may cause respiratory and throat irritation to some.
