In seed-eating finches in the Galapagos Islands, birds with large beaks are adapted to eat seeds with hard shells,
while birds with small beaks are adapted to eat seeds with soft shells.
If all the seeds in the Galapagos Islands were to develop softer shells as a result of long-term changes in the Earth's
climate, which of the following would be the MOST likely effect on the seed-eating finches?
Elimination Tool
Select one answer
A
Birds with large beaks would develop even larger beaks, while birds with small beaks would develop
even smaller beaks over many generations.
B.
Average beak size in the finches will decrease over many generations.
С
Birds with large beaks would develop smaller beaks, while birds with small beaks would develop
larger beaks over many generations.
D
No selection would operate because the finch populations on the Galapagos Islands meet all the
criteria for Hardy-Weinberg equilibrium.
Answer:
The answer might be D
Explanation:
The answer could be D because birds with larger beaks should be capable of eating soft shell seeds, as well as hard shell seeds. So natural selection would not occur because the finches with large beaks would not die as a result of not eating soft shell seeds. The finches with large beaks should be able to reproduce offspring with the same trait. And so should the finches with small beaks.
Average beak size in the finches will decrease over many generations is the most likely effect on the seed-eating finches.Therefore, the correct option is B.
What are finches?Finches are small to medium-sized passerine birds in the family Fringillidae. They are found throughout the world, but are most diverse in the tropics. Finches are known for their unique beak shape and size, which is specialized for feeding on a variety of different foods such as seeds, fruits, insects, and nectar.
The most likely effect on the seed-eating finches if all the seeds in the Galápagos Islands were to develop softer shells would be that birds with small beaks would have a selective advantage.
Therefore, the population of birds with smaller beaks would likely increase over time, while the population of birds with larger beaks would decrease.Hence, the correct option is B.

What factors are important in judging how helpful an energy resource is to us?
The factors which are important in judging the help fullness of energy resources to us are demand, storage of gas, weather forecast, nuclear and coal.
What are the important factors in judging the helpfulness of energy?The first factor is demand for heating, cooling, light, and processes varies in response to demand in terms of economic, technological, and efficiency measures. The second factor is Gas Storage and this has a term for energy “inventory” (since you can’t store electricity), i.e. the difference between supply and demand. Gas injections and withdrawals are announced weekly, and prices adjust accordingly.
The third factor is weather forecasts that is used to predict the weather events which are important considerations, affecting spot market prices and short-term contracts. Weather the forecast becomes reality is less critical to longer-term prices and last is generation changes while seemingly more localized, these changes can have a broad effect on the markets.
Nuclear retirement of older plants as they require re-licensing can cause fluctuations and coal plant conversions to natural gas to avoid scrubbing-technology costs can also cause fluctuations.
Therefore, The factors which are important in judging the help fullness of energy resources to us are demand, storage of gas, weather forecast, nuclear and coal.

What would happen if cytokinesis did not work properly?
1) DNA replication would not occur
2) A cell would have a nucleus with too many chromosomes
3) A cell would have two nuclei
4) New daughter cells would not have enough organelles or would be missing organelles
5) a cell would be smaller in size
Answer:
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result. so the cell would remain to be at rest not being able to separate into two individual cells

Which step happens first in DNA replication?
Answer:
Initiation
Explanation:
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains (Figure 1).

Answer:
normal and the mutant CFTR protein. How would you correct the mutant protein if you had the ability to tinker with it on a molecular level?
Corr-4a (bisamionomethylbithiazole C4) and VRT-325 were the first CFTR correctors discovered (quinazolinone C3 ). They are not, however, specific for CFTR and have been found to have low efficacy and high toxicity.
What is CFTR correctors?Correctors are the type of CFTR modulator even a small molecule that binds to CFTR and improves its functionality. is referred to as a "corrector."
Correctors assist the CFTR protein in forming the proper 3-D shape so that it can move or traffic to the cell surface.
And over 1,700 CFTR gene mutations have been discovered. Some are common, while others are uncommon and found in only a few people.
A CF corrector is a chemical chaperone that increases F508del-CFTR levels on the cell surface.
VX-809 (lumacaftor) is the most effective symptomatic CF corrector to date, according to a series of CF correctors.
Thus, these are some molecules that can fix mutated CFTR channel.
