Answer:
B. The horse and donkey are not members of the same species because their offspring are sterile.
Explanation:
The horse and donkey aren't members of the same species since the donkey has 62 chromosomes while the horse had 64 chromosomes and members of the same species need to have the same number of chromosomes. This leads to the mule having 63 chromosomes which is an odd number of chromosomes so it is sterile.
Answer:
It is due to the proofreading activity of RNA polymerase.
Explanation:
RNA polymerase is the most significant enzyme of transcription process which deals with the synthesis of RNA from DNA.
RNA polymerase reads the template DNA or antisense strand of DNA and helps in the addition of correct nitrogen bases to the growing RNA strand that is complementary with respect to the nucleotides present within the template DNA strand.
After the addition of bases to the growing RNA strand the proofreading process take place in to verify that all the incorporated bases within the growing RNA chain is correct or not.If any incorrect base is incorporated in the growing RNA strand then the proofreading process replace that incorrect base with the correct one.
All this processes occur in very quick succession that"s why RNA polymerase can locate a promoter sequence faster than two molecules can collide.
<h2>Answer:</h2>
Option B is correct.
B. shared; atoms
<h2>Explanation:</h2>
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Answer:
There are many advantages of geothermal energy. It can be extracted without burning a fossil fuel such as coal, gas, or oil. Geothermal fields produce only about one-sixth of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces. Binary plants release essentially no emissions.
