How can a pure white mouse help determine the genotype of a black mouse? (Hint: We cannot see genotype but we can see difference

sattari [20]

Answer:

A white mouse is purely recessive, and will produce black offspring if the other mouse contributes a black gene.

Explanation:

If Bb then the offspring will be 50% Bb and 50% bb. This is called a test cross, where we use a recessive to determine the genotype of a dominant phenotype.

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer

larisa86 [58]

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
x + y + z = 140 meters

According to the proportion theorem,

$\frac{x}{40} = \frac{y}{30}$

Solving for x, using cross multiplication:

$\frac{x}{1} = \frac{40y}{30}$

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

4y/3 + 6z/7 + 7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

positive impacts
Animals can be engineered to require less food, grow quicker, and leave behind less evironmentally damaging waste.
-Animals can be engineered to be more resistant to harmful and painful diseases.
-Animals can be engineered to produce more omega-3 fatty acids, to provide leaner meat, and to make more milk.
-Animals can be engineered so their tissues, organs, and cells can be transplanted into humans.
-Animals can be engineered to produce certain substances that offer a new source of medicine.
-Animals can be engineered to reproduce much faster.

negative impacts.

It is unethical.
-Some food companies have refused to use meat or milk that is from genetically engineered animals.
-Some consumers are complaining that the animal drug rules do not regulate genetically modified animals properly.
-This process is potentially dangerous and can be very harmful.
-When engineering animals the natural ecosystem can be disturbed.
-Some animals die in experiments while other are born deformed or huge.
-Animals may live in odd comditions that are affect their natural way of life.
-Most injected eggs do not end up creating a living animal.
