Explanation:
The first option, the others are normal
Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.
Answer:
They use a gene modification technique called CRIPSR-CAS9. The pigs have been given a gene that allows them to better regulate their own body temperature, whereby they burn fat, or at which animals consume their own fat.
Explanation:
British and Chinese scientists explained that they conducted the study by adding a mouse version of the UCP1 gene used for porcine embryos, which is used to regulate body temperature characteristic of most mammals, but not ordinary pigs.
It is problematic for pigs to maintain a stable body temperature, and this is especially complicated in pigs that are cold in the winter months because they have not been able to "store" fat.
Inserting the UCP2 gene could solve this problem.
Answer:
The precise definition of pH is "the negative common logarithm of the activity of hydrogen ion in solution". For practical purposes, the activity is approximated as concentration in moles/L: pH = - log 10 ([H+]) .
Explanation:
Answer:
-5 5/6
Explanation:
So the same thing as the last question I answered, we have to multiply the top row and the bottom row. However, the fractions in the photo are actually mixed numbers so we first have to make them into improper fractions.
1 and 2/3 would be: 5/3
-3 and 1/2 would be: - 7/2
So now we have to multiply them: 5/3 * - 7/2:
Same steps: 5 * 7 = 35; 3 * 2 = 6:
- 35/6, or we could simplify and make it a mixed number so and also add the negative sign:
6 goes into 35 5 times so: -5 and 5/6 or -5 5/6
