Answer:
Vascular dementia
Explanation:

Vascular dementia is disease of no known cure but it's effect can be treated or suppressed. It is characterized by patient or client suffering from it to have loss of memory, laughing or crying when it's unnecessary or at awkward times e.t.c it occurs as a result of damage of blood vessels in our brain or break down and it occurs as a result of stroke, diabetes and other factors.
There are choices for this question namely:
<span>A) genetic bottleneck.
B) sexual selection.
C) habitat differentiation.
D) founder effect.

The correct answer is founder effect. The definition of founder effect is the loss of genetic variation when a new population is established in a small number of individuals from a larger population. The larger population in the context is the ecosystem in Hawaii before it rose from the sea surface. After it rose above the sea surface, most organisms will not be able to survive in land but there will be a small population that can evolve from there.
Homeostasis, my friend.
Homeostasis is the process of maintaining a constant internal environment (temperature, water content, available energy, available oxygen & concentration of wastes in the blood.) Some animals are able to do this and are called endothermic or 'warm-blooded' (like humans). However, not all animals are able to do all of this - and they are referred to as ectothermic or 'cold-blooded.'
Animals need to be able to maintain a stable internal environment because if they do not, they will most likely die. Animals need warmth to survive, so they need to be able to have a constant body temperature whether it be by using their body to create warmth or having to sit in the sun to keep warm,
Hope this helps.
