Answer:
The options
a.) neutrophils
b.) lymphocytes
c.) basophils
d.) monocytes
The CORRECT ANSWER IS a.)
a.) neutrophils
Explanation:
Neutrophils are grouped as granulocytes (they possesses clearly seen cytoplasmic granules). It functions as the body's bacteria killers, and their numbers rises at a swift rate in times of acute bacterial infections. Neutrophils are active phagocytes; they are particularly partial to feed on bacteria. It make up around 40 percent to 60 percent of the white blood cells in the body, and its the first cells produced by the body as a response to a bacterial infection.
The correct answer is:
Grow a legume crop to support the development of root nodule
The best way that a farmer could increase the amount of nitrogen in his fields without adding synthetic fertilizer is to grow a legume crop to support the development of root nodules. This is because legumes have a symbiotic relationship with bacteria found in the soil.
Explanation:
Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation.The plant root cells convert sugar into organic acids which then supply to the rhizobia in exchange, hence a symbiotic relationship between rhizobia and the legumes.
Answer:
The correct answer is: A. Only the best-adapted animals in a population survive.
Explanation:
- Natural Selection is the process by which the individuals of a species which has the potential to sustain and survive in adverse or changing environment gets a survival advantage over those individuals which are unable to adapt themselves to altered environmental conditions.
- As the less potent individuals die in altered environmental conditions the adaptable individuals escapes competition with them for natural resources.
- Evolution causes species to alter their characteristics depending upon the demand of the conditions. These changes can vary, can be less or drastic.
- Animals pass all the newly adapted traits to the successive generations either as genetic traits or as acquired traits, as this is necessary for the offspring to survive in the altered environment.
- Natural selection is best defined as "the survival of the fittest".
