Alzheimer's disease is characterized by:
a. tdp-43 and apoe-4
b. hydrocephaly, shuffling gait, and soft voice
c. white matter hyperintensities caused by multiple infarcts
d. amyloid plaques and tau neurofibrillary tangles

The correct answer is d amyloid plaques and Tau neurofibrillary tangles.

Explanation:

Alzheimer"s disease is one of the most devastating neurodegenerative disease occur in human.

    Alzheimer disease is caused due to the accumulation of amyloid precursor protein or misfolded proteins in the brain resulting in the formation of neurofibrillary tangles which ultimately leads to degeneration and loss of most of the vital functions of neurons.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
