The x chromosomes are found in the nucleus of body cells in a women. Thus option b is correct.

Chromosomes are defined as a thread like structure located in the nucleus of every cell in our body and are formed of tightly coiled DNA surrounding proteins.

Chromosomes plays very important role in human body.

The primary purpose of chromosomes is to transport DNA and genetic information from parents to offspring.

It play a vital role during cell division.

They keep DNA from becoming twisted and damaged.

There are basically two types of chromosomes.

Thus, the x chromosomes are found in the nucleus of body cells in a women. Thus option b is correct.

(B)  A suspect's mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene

Explanation:

I got it right lol and have a good day <3

Option B A suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene is correct.

Mitochondrial DNA (mtDNA) typing is used in forensic science to analyze DNA evidence in cases where the DNA material is degraded or present in small amounts, such as in hair shafts, bones, and teeth.

mtDNA typing is also useful in cases where a person's nuclear DNA (which is unique to each individual) is not available or is contaminated with DNA from multiple sources.

mtDNA is inherited maternally and is present in multiple copies in each cell, making it more abundant and resistant to degradation than nuclear DNA.

Forensic scientists can compare the mtDNA profile of a suspect with mtDNA evidence found at a crime scene to determine whether the suspect's DNA could have contributed to the evidence.

Since mtDNA is not unique to each individual and is shared among maternal relatives, mtDNA evidence alone cannot definitively identify a suspect, but it can help exclude individuals who do not share a common mtDNA profile with the evidence.

Hence option B is correct.

Answer:

Its the Ocean.

Explanation:

This is the correct answer I hope this helps you out.

Oceans hold the least amount of carbon compared to glaciers, plants, and soil.  Therefore, option (A) is correct.

Carbon exists in the oceans mainly in the form of dissolved inorganic carbon (DIC) in the form of bicarbonate and carbonate ions. The oceans act as a carbon sink, absorbing around 25% of the carbon dioxide emitted by human activities. However, the amount of carbon stored in the oceans is relatively low compared to other carbon reservoirs such as glaciers, plants, and soil.

Glaciers are made up of compacted snow and ice and can hold large amounts of carbon. Glaciers are important for the carbon cycle as they can sequester carbon for hundreds of years. Plants also store large amounts of carbon in the form of organic matter through the process of photosynthesis. Soil also stores significant amounts of carbon in the form of organic matter.

Overall, while oceans do play a role in the carbon cycle, they hold the least amount of carbon compared to other reservoirs. The carbon cycle is a complex system that involves many reservoirs and processes, and understanding the dynamics of each of these components is crucial to our understanding of global climate change.
