Answer:
C. +23.1 kJ/mol
Explanation:
the formula to use to calculate the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells is:
ΔGt = RTIn
+ ZFΔV
let's list the values of the data we are being given in the question to make it easier when solving it.
Z= 1
F= 96500C (faraday's constant)
ΔV= 160mV = 0.160V
R= 8.314( constant)
T= 15ºC ( converting our degree Celsius into kelvin, we will have 273.15k+ 15 = 288.15K)
∴ T= 288.15K
Putting it all together in the formula, we have:
ΔGt = 8.314 × 288.15 × 2.303 log
+ 1 × 96500 × 0.160
ΔGt = 5517.25
+15440
ΔGt = 5517.25
+15440
Given that the pH differential gradient across the membrane is 1.4pH units. It implies that;
ΔGt = 5517.25 × 1.4 + 15440
= 7724.15 +15440
= 23164.15 Joules/moles
= +23.1 KJ/mole
Answer:
The correct answer is - develop new methods to test the hypothesis.
Explanation:
Human produce offsprings long time and development also take a long time in general and then to test a hypothesis, regarding the gene therapy helps to treat a disease, would take even more time.
So testing this hypothesis required developing a new method as other options are not possible. You can not change the time it takes in reproduction. Giving up is not the option in science.
The piece of cheese in the refrigerator had the least amount of chemical change.
- Moulding occurs on substances which are warm and moist
- Mold thrives in warm and humid places
- In refrigerators, the environment is cool and dry
- This environment hinders the growth of mold
- The bacteria and fungi require optimum temperatures to flourish, which is not present in a refrigerator
- The cheese placed outside and on the counter will grow mold as those environments do not arrest the growth of mold
- Refrigeration ensures that food is not spoilt
Therefore, the least amount of chemical change takes place on the cheese placed in the refrigerator.

Answer:
1/16 are ovoid
Explanation:
Hello!
From an AaBb genotype we can obtain four possible gametes AB, Ab, aB and ab. With the Punnett square we can observe the crossing. In the second Punnett square we can see the form A– B–
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
AB Ab aB ab
AB A-B- A-B- A-B- A-B-
Ab A-B- A-bb A-B- A-bb
aB A-B- A-B- aaB- aaB-
ab A-B- A-bb aaB- aabb
The genotypes of the form A– B–, A– bb and aa B– have triangular seed capsules (15 of 16), while the seed capsules of the aa bb genotypes are ovoid (1 of 16).
