The answer would be B) Nitrogen Trioxide
The plasma membrane is described as a fluid mosaic model because its made up of a phospholipid bilayer, allowing it easily to bend and move along without breaking or ripping the membrane due to the hydrophobic and hydrophilic poles of the bilayer.
Answer:
Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were to be unraveled, the genetic material they contain would measure roughly 2 metres (about 6.5 feet) in length. The compactness of chromosomes plays an important role in helping to organize genetic material during cell division and enabling it to fit inside structures such as the nucleus of a cell, the average diameter of which is about 5 to 10 μm (1 μm = 0.00l mm, or 0.000039 inch), or the polygonal head of a virus particle, which may be in the range of just 20 to 30 nm in diameter.
Answer:
Incorrect statement A
Explanation:
The neurotransmitter molecules diffuse across the synaptic cleft where they can bind with receptor sites on the postsynaptic ending to influence the electrical response in the postsynaptic neuron.
Selective breeding. Natural selective breeding is usually carried out by females of a species. By favouring certain traits in males (usually in term of how colourful they are, eg: varieties of fish and birds of paradise), the genes that get passed on to the next generation are selected by the females. This is why in some species the males are more colourful and extravagant-looking than the females.
