Answer:

Explanation:

Sugars provide all the elements necessary for the formation of a macromolecule, carbohydrates. Although sugars can also be found in nucleic acids, their composition depends on other molecules that are not supplied by sugars.

Sugars are the carbohydrate-forming molecules, which are very important in our diet. In fact, the amount of sugar present in carbohydrates, forms classes called monosaccharides (one sugar), osids (hydrolyzable sugars), disaccharides (two sugars) and polysaccharides.

The all-or-none phenomenon as applied to nerve conduction states that the whole nerve cell must be stimulated for conduction to

Sphinxa [80]

Answer:True

Explanation:

Nerve impulse must reach a certain threshold in a neuron before action potential can be generated to intiate conduction of action potential.

Therefore if mutiple impulses are generated and these are not upto thresholds , no matter how strong the stimulI are-NO ACTION POTENTIAL WILL BE GENERATED.

THIS IS ALL OR NONE PRINCIPLE

The all or none hypotheses can be best explain with flushing of the water closet after using it. If required volume of water is not pumped into the water closet storage above, no matter how long the handle is push, FLUSHING WILL NOT TAKE PLACE.Thus the threshold volume of water must be met.

Mendel carried out his research on garden peas. You should remember that he used seven pairs of traits. Modern geneticists have

Goshia [24]

Answer:

A. the two genes on chromosome 1 are more than 50 mu apart.

Explanation:

Two or more genes present on the same chromosomes are the linked genes. Linked genes do not assort independently and do not exhibit crossing over. Therefore, the linkage of genes results in deviations from Mendel's law of independent assortment. However, if the linked genes are present far from each other on the same chromosome, they may exhibit crossing over.

The greater the distance between the linked genes, the higher are the chances of crossing over. Crossing over of linked genes would result in some of the progeny to have the new gene combinations as it occurs during an independent assortment of two genes. Therefore, Mendel observed an independent assortment of two genes present together on chromosome 1 since they were present far apart from each other (more than 50 mu apart).

Calculate the rate of photosynthesis (mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 7mm from

ZanzabumX [31]

Answer:

With 6 we should multiply gross photosynthesis (as we were measuring gross photosynthesis for 10 min).

Explanation:

According to this question:-

Net photosynthesis- 3mm/20min- 1.5mm/10min

Cellular respiration- 1mm/15min- 0.66mm/10min

Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)

Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr

As we gage the photosynthesis rate in hr.

Answer:

Oxygen.

Explanation:

Oxygen molecule that is produced in the light dependent reactions. This shutting down of linear electron flow greatly affected the production of oxygen. Photosystem II gains replacement electrons from splitting of water molecules into hydrogen ions (H+) and oxygen atoms so if the electron flow is disturbed then oxygen production is greatly affected.
