What causes an ionic bond to form between sodium and chlorine?
Answers
Answer:
The loss of an electron
Explanation:When sodium (Na) and chlorine (Cl) are combined, the sodium atoms each lose an electron, forming cations (Na+), and the chlorine atoms each gain an electron to form anions (Cl−
Answer:
"Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. ... If sodium can transfer it's "spare" electron to chlorine, both atoms will satisfy their full outer shell requirements, and an ionic bond will be formed."

Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time? Plato question
Answers
Answer:
Due to inclusion of more steps of photosynthesis.
Explanation:
My model is more advance than the student's original model which provides more information about the process of photosynthesis to the learners by explaining various parts of photosynthesis. My model presents the various steps of photosynthesis in a very efficient way with the help of including some extra parts. The student's original model is not more advance so it can't provides more information about the process of photosynthesis so that's why my model provides more information about photosynthesis.
Answer:
This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products. This model also shows the number of each molecule created, which the original model doesn’t do.

While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, she isolated and cultured a single cell from this group. She noticed that the progeny of this cell were not producing a certain protein and that this affected their survival. The mutation would be most harmful to the cells if it resulted in ______.
Answers
Answer:
The correct answer is - a single nucleotide insertion near the start of the coding sequence.
Explanation:
Insertion mutations are the mutation that takes place when there is an extra nucleotide is added to the DNA strand during replication and causing the particular protein translation or inhibits the translation if present at the start codon.
It did not allows the translation in this sequence, Deletion, and insertion both are a dangerous mutation that causes the production of unwanted protein or not producing the protein and if this protein is essential for surviving it will lead to cell death.

Which of the following statements about cardiac muscle is true? a. Cardiac muscle is like smooth muscle, because smooth muscle has a banded appearance. b. Cardiac muscle is like smooth muscle, because it contains no bands. c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle. d. Cardiac muscle is like skeletal muscle, because skeletal muscle has involuntary contractions.
Answers
Answer:
c. Cardiac muscle contains bands like skeletal muscle, but its contractions are involuntary like smooth muscle.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Cardiac muscle is also referred to as myocardium and it's one of the three (3) muscles found only in the heart of vertebrates, the other two (2) being smooth muscle tissue and skeletal muscle tissue.
Cardiac muscle contains bands like skeletal muscle referred to as sarcomeres (contractile units), but its contractions are involuntary like smooth muscle and it's typically being regulated by the sinoatrial node of the heart.
