Sodium and oxygen colvalent bond

Biology
1 answer:
snow_lady [41]3 years ago
7 0

Answer AND Explanation:

When sodium atoms bond with one oxygen atom they form a covalent bond. However, there has to be two sodium atoms each with an extra electron that are donated to oxygen. Each of these sodium atoms gives oxygen one electron, allowing the oxygen atom to have a full shell with eight electrons. The sodium atom loses one orbital level since the electrons are donated.

4Na + O2 → 2Na2O

Sloan [31]

Answer: Colon cancer

Explanation:

All cancers, but especially colon and rectal cancers, commonly referred to as colorectal cancer (CRC), have hereditary factors that potentially increase one’s risk.

Genetic testing is determine if there is an increased risk of colon cancer. Apolipoprotein E (apoE) plays a major role in the metabolism of bile acids, cholesterol and triglycerides, and has recently been proposed as being involved in the carcinogenic process. Given the potential role of bile acids in colorectal cancer etiology, it is reasonable that colorectal cancer risk might be modified by apoE genotype. The absence of an e3 apoE allele significantly increased the risk of colon cancer especially for individuals above 50years.

Zepler [3.9K]

Diatoms contain chloroplasts that have four membranes. These four membranes are evidence of secondary endosymbiosis (Option c).

<h3>What is secondary endosymbiosis?</h3>

Secondary endosymbiosis is a hypothesis used to explain why diatom chloroplasts have four membranes.

According to this hypothesis, diatoms received different genes from distinct photosynthetic and non-photosynthetic ancestors.

The acquisition of genes of different ancestors led to diatoms having chloroplasts with four membranes.
