A) y = -1/4(x - 6)² + 1
The equation of the parabola with its focus at (6,2) and its directrix y = 0, is determined as y = 1/4(x - 6)² + 1.
Equation of the parabolaFocus at (6,2) and its directrix y = 0.
Focus equation is given as: (h, k + c) = (6, 2)
Directrix equation is given as: y = k - c = 0

D. Otonic
D. hypertonic
Answer:
C. isotonic
What is a isotonic solution?
Two solutions exerting the same osmotic pressure over a semipermeable barrier are said to be in an isotonic solution. Without affecting the concentration of solutes on either side, this condition enables unrestricted passage of water over the membrane.
What is osmosis?The tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.

The ancestors of elephants inhabited every continent except Antarctica and Australia. But the Asian and African elephants are the only ones to survive. Why?
Options:
A) Dinosaurs killed all other elephant species.
B) Asian and African elephants killed off other species of elephants.
C) Asian and African elephants adapted well to their environments.
Asian and African elephants adapted well to their environments. Thus, the correct option is C.
Environment of Antarctica is not suitable for elephants why?
The world's coldest location is Antarctica. Additionally, it is the windiest and driest. Almost the entire year, the continent is covered in snow. Due to the extremely harsh temperatures and lack of healthy soil, Antarctica is therefore unsuitable for raising elephants and cultivating crops. Elephants eat grass, while the entire continent of Antarctica is covered in snow. In this database, there are currently 25 (8,17) living elephants located in Australia.
Although they can be found in a variety of environments, including deserts, swamps, and highlands in tropical and subtropical areas of Africa and Asia, they are most frequently found in savannas, grasslands, and woodlands.

A species with narrow niches that can survive in a small range of environmental conditions are
A. K-selected species
B. r-selected species
C. Generalist species
D. Specialist species
Answer:
D. Specialist Species
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.
