Na+ is a(n) _____, and Cl- is a(n) _____ .

Answers

Answer 1
Answer:

Answer: Na^+ is a cation and Cl^- is an anion.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.  

Electronic configuration of sodium:

[Na]=1s^22s^22p^63s^1

Sodium atom will loose one electron to gain noble gas configuration and form sodium cation with +1 charge.

[Na^+]=1s^22s^22p^63s^0

Electronic configuration of chlorine:

[Cl]=1s^22s^22p^63s^23p^5

Chlorine atom will gain one electron to gain noble gas configuration and form chloride anion with -1 charge.

[Cl^-]=1s^22s^22p^63s^23p^6

Answer 2
Answer: the answer is Cation;anion

What is one reason some leaves are spiny, or needle-shaped? A. to increase the rate of formation of food in leaves B. to reduce water loss from leaves in dry climate C. to store food in dry climates?

Answers

Answer: B. to reduce water loss from leaves in dry climate.

Explanation:

Spiny or needle shaped leaves is a kind of adaptation in plants which is typically seen in plants that survive in dry climatic conditions. The needle shaped leaves reduces the surface area of the leaves which prevents the loss of water through transpiration.

B, because of the dry climates, they need to retain as much water as they possibly can.

ANSWER: The deserts, tropical forest, and tundra are considered to be fragile ecosystems because of the long regeneration time when vegetation has been destroyed.

Fragile, yes. Not necessarily unstable unless we humans mess it up. The reason it's fragile has to do with the cold temperatures and difficult growing conditions, HOPE THIS HELPS!! :)

"Ribosomes are described as the site of protein synthesis. Ribosomes consist of RNA and protein combined into a very particular shape. As a ribosome moves along an mRNA transcript, amino acids are joined together by peptide bonds. The formation of peptide bonds is facilitated by rRNA in the ribosome. Thus, rRNA can be described as a(n)"

Answer:

Catalyst

Explanation:

Translation is the second process of gene expression which occurs in the ribosomes of living cells. The ribosome is a complex of Ribosomal RNA (rRNA) and proteins. Translation occurs when ribosomes attach to the transcribed mRNA molecule to read its codons using the transfer RNA (tRNA's) anticodon. The tRNA then carries amino acid that corresponds the codon it reads to the growing polypeptide chain.

In this process, amino acids are attached to one another forming a peptide bond. This linking of one amino acid to another is facilitated by rRNA's as it helps catalyzes the reaction like an enzyme. Ribosomal RNA catalyzes the reaction that forms a peptide bond between the amino acid in the A site of the ribosome and the growing polypeptide (future protein) in the P site.
