When carter first moved into his neighborhood, he noticed hundreds of frogs on the roads after a rain storm. lately, carter has seen less than four or five frogs on his five-minute drive through the neighborhood. which of the recent events is a reasonable conclusion based on carter's observations? a drought has impacted the population size of the frogs. a new housing development has led to extinction of the frogs. the beginning of the winter has created temperatures too cold for the frogs. increasingly warm temperatures have dried the skin of the frogs leading to death.

 A drought has impacted the population size of the frogs.

Explanation:

The frogs are the amphibians who require both water and terrestrial habitats to survive and reproduce. The rainwater accumulates over the terrestrial regions can provide an ideal environment for the survival of the frogs.

According to the given situation, Carter noticed hundreds of frogs on the road after rain storm as the road environment was suitable for the survival of the frogs. But later on he observed less than four or five frogs. This may be because of the fact that the road might not be left with water which could be probably due to drought (a drought is a condition where a region does not receive appropriate amounts of rainfall which leads to the dry and hot environment).

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
