Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds.
Calcium, which is a metal, donates 2 electrons to chlorine.
The individual calcium atoms become ions with a negative 2 charge.
The bond between calcium and chlorine makes the atoms stable.
Calcium and chlorine attract each other.
Which best describes Shameeka’s error?
Calcium is a metal, so it donates protons, not electrons.
The individual calcium atom has a positive, not negative, 2 charge.
The bond formed makes the atoms unstable, not stable.
Calcium and chlorine repel, not attract, each other.
Answer:
The individual calcium atom has a positive, not negative, 2 charge.
Explanation:
The error in her study is in the second line of her note which suggests that the individual calcium atoms becomes ions with a negative 2 charge.
When atom loses electrons, it has a net positive charge on it. Not a negative charge. This is because the number of protons is now more than electrons. Therefore, a net charge on the calcium atom will be a positive one. This is her mistake.Answer:
B) The individual calcium atom has a positive, not negative, 2 charge.
Explanation:

1.The open area of DNA where replication or transcription can take place is called A.replication Bubble B.replication form c.replication strand d.replication origin
2. Once the two strands of DNA are separated, what prevents them from assuming their double- helical shape? A.Other proteins hold the strands apart B.They are too far away from each other C.Each strand has opposing charges, which keep them repelled D. All of the above
3.How does DNA polymerase move along each strand of DNA? A.Both move towards the replication fork B.Both move away from the replication fork C.One moves towards from the replication fork and the other moves away from it D.There is only one DNA polymerase on the DNA at a time
4.How can each copy of DNA at the end of replication be compared? A.Each copy is identical to each other B.Each copy is different from each other C.They are 90% similar D.They are 50% similar
5.In the event of a mismatched nucleotide , which molecule is able to backtrack , "proofread ," and correct the nucleotide sequence? A.DNA Proofreadase B.DNA Polymerase C.DNA Helicase D.DNA Primase
Answer:
1) Transcription Bubble.
2) Replication Forks
3)
Explanation:
1) The region of opened- up DNA is called a Transcription Bubble. In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complentary RNA transcript.
2) The Replication Forks hold the 2 separated strands of DNA apart, preventing then from assuming their double helix shape... in order to replicate all your DNA its faster to replicate DNA if your doing it in many different areas at the same.
3)Since DNA polymerase requires a free 3` OH group for initiation of synthesis, it can synthesize in only one direction by extending the 3` end of the preexisting nucleotide chain. Hence, DNA polymerase moves along the template strand in a 3`-5` direction, and the daughter strand is formed in a 5`-3` direction.
I don't know 4 and 5
The answers to the following questions are:
Replication bubble.Replication fork One moves towards from the replication fork and the other moves away from it..Each copy is identical to each otherDNA PolymeraseWhat is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
A particular kind of enzyme called DNA polymerase (DNAP) is in charge of creating fresh nucleic acid molecules that are copies of the original DNA. Polymers are huge compounds consisting of smaller, repeating units that are chemically linked to one another. Nucleic acids are polymers.

how many body systems are in eating a single bite of turkey? PLSS HELP its duo in abt 6 mins!!
Answer:
There are 4 systems involved in this activity. these systems are: the skeletal, muscular, circulatory and digestive systems.
Explanation:
To eat a single bite of turkey it is necessary that 4 systems come into play and work together for this activity to be possible.
First, it is necessary that the turkey is brought to your mouth through the movement of its members. In that sense, the resqueletico and muscular systems will act because it is through them that the movements of the members are created.
Then you will need to bite the turkey, chew it, moisten it with saliva, swallow it and digest it. This work will be done with the digestive system that will manage all of these activities.
Finally, your body will need to absorb the elements that make up the turkey pedal that you ate and that were rescued by digestion, these elements are nutrients, proteins and others. All will be absorbed through the work of the circulatory system, which through the blood will carry the elements throughout the body.

Explain why enzymes are essential or important to maintaining
homeostasis in living things.
Answer:
Enzymes are proteins that catalyse (speed up) vital chemical reactions inside the body. Enzymes will only function properly under a small range of certain conditions, such as preferred pH and temperature. If any conditions are outside their specific range then the enzymes cannot function. This could cause the organism to die. Homeostasis relies on automatic control systems that include nervous responses (nervous system) or chemical responses (endocrine system). Receptors and effectors are also needed

Which would have most likely stopped Mendel from finding a pattern in his
results?
A. If having a wrinkled seed had been a recessive trait
B. If garden peas had used sperm and egg to reproduce
C. Being short is a recessive trait
D. If seed color and shape were located on the same chromosome
Answer:
D. If seed color and shape were located on the same chromosome
Explanation:
If seed color and shape were located on the same chromosome, they would not be inherited independently of one another.
Genes on the same chromosome are more likely to be inherited together. The only way they could be inherited independently is if crossing over occurred between the two genes.
Therefore, this would argue against Mendel's law of independent assortment.

Why don't we all look the same if all humans have the same number of chromosomes
that contain the same genes?
Answer:
A small number of genes are slightly different in everyone which results in everyone looking different from one another. Each person has two copies of each gene, one from your mother and father which makes you look somewhat alike. Their are alleles that have small differences in them which are different from someone elses DNA bases which make you look different.
