In small intestine water is extracted from digested food.
Can I have the brainliest?
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.
<u>Answer:</u>
A theory would be entirely replaced if a new information is discovered that contradicts with the previous theory.
Explanation:
Theories are made after being properly investigated and by having a large amount of supporting data.
But theories can be subjected to entirely change and be replaced if a new theory comes up that contradicts with the previous theory. As science is an emerging field and new researches are conducted day by day so previous theories can be wrong. However, the new theory should have enough evidence and reasoning to prove that the previous theory was wrong.
Answer:
2.23 atoms
Explanation:
In this question, we first need to change the mass of Nitrogen to moles by using the formula;
mole = mass ÷ molar mass
Molar mass of Nitrogen = 14g/mol
Mass = 5.2x10^-23 grams
mole = 5.2x10^-23 ÷ 14
mole = 0.371 × 10^-23
mole = 3.71 × 10^-24 mol
Number of atoms in Nitrogen atom = 3.71 × 10^-24 mol × 6.02 × 10^23 atoms (avagadro constant)
= 22.3342 × 10^(-24+23)
= 22.33 × 10-¹
= 2.233 × 10°
= 2.23 atoms
