Answer:
the humus contains the minerals necessary for chlorophyll synthesis
Explanation:
<em>The yellowness of leaves in plants can be attributed to inadequate chlorophyll in the plant</em>. The chlorophyll is responsible for the greenness appearance of the leaves of plants and when it is present in inadequate quantity, the leaves appear yellowish in color.
<u>Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron</u>. It thus means that the humus supplied to the soil of group 1 plant has the necessary minerals to synthesize chlorophyll while the soil of group 2 plants is deficient in some or all the minerals required for chlorophyll synthesis.
That fact can be explained by the similarity in their genes.
Dogs and coyotes are from the same class, family and genus (Mammalia, Canidae, Canis).
This is almost enough for their offspring to be viable. But if the DNA is similar (which it is) offspring the chances of viable and fertile offspring is high almost at 100%.
Hope it helped,
Happy homework/ study/ exam!
Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.
Answer:
The small intestine is about 20 feet (6 meters) long and folds many times to fit in the abdomen. Although it is longer than the large intestine, it is called the small intestine because it is smaller in width.

Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.
