Answer: The aluminum atom loses electrons to form an ion.
The ion that is formed is <u>positive</u>
<u></u>
<u>Second Part of the question:</u> What is the name of the aluminum ion?
<u>
</u>Answer : <u>Al+3</u>
Explanation: <em>An aluminum ion has a charge of +3. It is not a neutral atom. It has a + charge, the electrons must have been taken away (electrons have a negative charge). Since the atomic number is 13, the number of protons is thirteen. In a neutral atom, there would be thirteen electrons. You take away 3. There is 10 electrons in Aluminum Ion. </em>
Okay, so this is physics. What is the meaning of KE? It's Kinetic Energy. What is the meaning of GPE? It's Gravitational Potential Energy. So how do you calculate either, and what are their significances? Kinetic -> motion, Gravitational potential energy -> energy that can be used to do work due to gravity. So is the bowling ball moving, or is it someplace it can fall from, or both?
Kinetic energy is calculated as 1/2 * mv^2, where m is the mass of the object, and v is the velocity. Potential energy for conservative forces is the product of the force and the distance over which it can do work. Thus in the case of GPE, it is the weight multiplied by the height, as gravity is a conservative force. What is the weight? It's not equal to the mass.
Hopefully these hints will get you thinking.
Answer:
d. DNA polymerase begins adding nucleotides at the 5' end of the template
Explanation:
Polymerase DNA always works in one direction, synthesizing the new 5' to 3' oriented chains and adding nucleotides to the 3' end of a new synthesis chain by forming phosphodiester bonds between the phosphate of a nucleotide and the sugar of the anterior nucleotide.
Because DNA polymerase only acts in a 5' to 3' direction, replication along a chain, the leading chain, occurs continuously. The synthesis of the opposite chain, the delayed chain, occurs discontinuously because the DNA polymerase must wait for the replication fork to open. Over the delayed chain, short segments of DNA called Okazaki fragments (named after Reiji and Tsuneko Okazaki, the scientists who discovered these fragments) are synthesized as polymerase DNA works out of the replication fork. Ligase DNA catalyzes the covalent bonds between Okazaki fragments in the delayed chain to ensure there are no gaps in the phosphodiester skeleton. Finally, the first ones are removed and these gaps are filled by the DNA polymerase.
Answer:No, viruses and some illnesses cannot be cured with antibiotics
Explanation: Because viruses are necessarily "hackers who reprogram your pc(cells)" Antibiotics can kill normal cells along the process, thus harming your cells too. An ideal situation for antibiotics would be bacteria infection where it kills the bacteria
In order to grow your cells need to expand and divide in order for your body to grow.
