Answer:
Contemporary light microscopes are able to magnify objects up to about a thousand times. Since most cells are between 1 and 100 μm in diameter, they can be observed by light microscopy, as can some of the larger subcellular organelles, such as nuclei, chloroplasts, and mitochondria.
A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.
Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA.
If the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.

Answer:
2.47 m/s backwards
Explanation:
From the law of conservation of momentum,
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂...................... Equation 1
Where m₁ and m₂ = mass of the first basketball player and second basket ball player respectively, u₁ and u₂ = initial velocity of the first basket player and the second basketball player respectively, v₁ and v₂ = The final velocity of the first basket ball player and second basket ball player respectively.
Making v₁ the subject of the equation,
v₁ = (m₁u₁ + m₂u₂ - m₂v₂)/m₁.......................... Equation 2.
Given: m₁ = 87.2 kg, m₂ = 102.0 kg, u₁ = 7.0 m/s, u₂ = -5.2 m/s, v₂ = 2.9 m/s
Note: u₂ is negative because it moves towards the first basket ball player.
Substitute into equation 2
v₁ = [87.2(7.0)+102(-5.2) - (102×2.9)]/87.2
v₁ = (610.4-530-295.8)/87.2
v₁ = -215.4/87.2
v₁ = -2.47 m/s.
Thus the velocity of the 87.2 kg player = 2.47 m/s backwards.
Answer:
The ban was intended to prevent the imminent extinction of ospreys, peregrine falcons, and bald eagles, our national bird, among other species; they were vulnerable because DDT caused a fatal thinning of eggshells, which collapsed under the weight of the parent incubating them.
Explanation:
The hidden cost was to control pests was washing off into rivers and streams, poisoning fish, birds, and even humans with toxic chemicals.
