False, frozen water is denser than liquid water and does not allow lake organisms to survive water.
<h3>Density of Frozen water and Liquid water</h3>
By definition, density is the mass per unit volume of a substance, a property which is characteristic to each substance.
By convention, solid state of a substance are said to be denser than liquid state of the same substance. Hence, it follows that frozen water is denser than liquid water and does not allow lake organisms to survive.

The answer is Command Economy<span />
The proportion of field mice weighing more than 33 grams in the distribution will be about 0.2275
- Mean, μ = 25 grams
- Standard deviation, σ = 4 grams
- Score, X = 33 grams
We need to calculate the P(Z > Zscore)
Recall :
Zscore = (X - μ) ÷ σ
For X > 33 :
Zscore = (33 - 25) ÷ 4 = 2
Therefore, the probability would be expressed as :
P(Z > 2) = 1 - P(Z < 2)
From the normal distribution table :
P(Z < 2) = 0.97725
Therefore,
P(Z > 2) = 1 - 0.97725 = 0.02275

Answer:
Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness.
Generic pharmaceuticals are significantly cheaper than name brand ones because generic pharmaceuticals are not protected by patent law, so the lack of barriers to entry and increased competition keep prices down.
Also, the makers of generic drugs do not have to cover the cost of developing and marketing a new product.
