Answer: Option (d) is the correct answer.
Explanation:
Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.
But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.
This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.
Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.
Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.
Answer: Which of the following statements correctly compares transcription in prokaryotes and eukaryotes?
Explanation: It would be B
Answer:
Option B
Explanation:
ALL options are as follows -
a. teosinte and maize can produce fertile hybrids.
b. teosinte and maize have similar chromosomes.
c. Both Teosinte and maize have naked, soft kernel.
d. Teosinte and maize can produce fertile hybrids
Solution
Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.
During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.
He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.
Option B is correct
Answer:
When I first read this question, all I could think about was the capsized fishing charter called, “the Erik”. The inept captain and crew of this boat caused the death of four passengers while three others remain missing. This disaster occurred back in 2011. I knew two of the passengers. One was recovered in 2013. The other is still listed as missing. However, this question concerns the “best story”. So, I’ll give you the accounts of my own experience. Back in 2013, my group of long-range fishing friends had chartered our annual 8-day trip out of Point Loma, San Diego. We had always chartered the same boat; the Shogun. At our traditional dinner the night before boarding, I remember the most notable topic being discussed was the remnants of Hurricane Ingrid. Ingrid had caused high winds and seas in the area where we wanted to fish.
