Answer:
The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.
Explanation:
Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.
On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.
The essential objective of "proofing" is to fill in as an apparatus for client confirmation that the whole employment is exact. Prepress sealing is a savvy method for giving a visual duplicate without the cost of making a press verification. On the off chance that mistakes are found amid the printing procedure on the press, remedying them can demonstrate expensive to one or both sides included.
Answer:
Explanation:
Fast-twitch muscle also uses glycolysis to produce energy, but it skips harvesting energy from pyruvate, a process that takes oxygen. Instead, pyruvate gets converted into a waste product, lactic acid, and released into the bloodstream
Cervical plexus is the major branch of phrenic nerve, going
through the thorax to give innervation of the diaphragm. Nerve impulses from
the inspiratory centre in the brain travel down it, causing contraction of the
diaphragm, so that inhalation can occur.
Answer:
The correct answer is: A. active transport requires energy.
Explanation:
- Active transport can be defined as the physiological process by which molecules are enforced to migrate from a region where their concentration is low to a region where their concentration is high across a semi-permeable membrane. This occurs by the expenditure of energy. This type of movement is usually carried out by the integral membrane transport proteins or carrier proteins those remain interspersed across the plasma membrane.
- Passive transport can be defined as the physiological process in which no energy expenditure is required. This is because in this form of transport, molecules move from a region where their concentration is high to a region where their concentration is low, that is, down the gradient of their concentration, across a semi-permeable membrane. This type of movement can be mediated by simple diffusion or with the help of membrane transport proteins.
