The features of this model provide evidence for which explanation of why all growing strands are synthesized in a 5' to 3' direction?
(A) The two strands need to be antiparallel to bond properly.
(6) Thymine and adenine would not bond properly if the strand grew from 3 to 5.
(C) The translation of mRNA occurs in the 5 to 3' direction; therefore, the growing DNA strand must also grow in the
5 to 3 direction
(D) The phosphate group, attached to the 5' carbon of the TMP, forms a covalent bond with the oxygen atom
attached to the 3' carbon of the growing strand.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
