The oceanic crust is denser than the continental crust.
Also, the oceanic crust consists mostly of basalt.
What is the oceanic crust made of?
The topmost layer of the tectonic plates' oceanic part is called the oceanic crust. It is made up of two oceanic crusts: the upper crust, which contains pillow lavas, and the bottom crust, which is made up of troctolite, and ultramafic cumulates. The crust sits on top of the hard mantle's topmost layer.
Dark-colored rocks named basalt and gabbro make up the majority of the marine crust. It is lighter-colored rocks called andesite and granite that make up the continental crust, which is thinner and denser. Because of its low density, continental crust "floats" high above the viscous mantle, generating dry land. It develops as magma rises to fill the space between divergent tectonic plates and is consumed in subduction zones.

A) Yes, Jan should undergo genetic sequencing.
BRCA1/BRCA2 are the causes of 20-25% of all hereditary breast cancers, so if Jan's mother and sister both have breast cancer, then the odds are that she has BRCA1 as well.
B)
Pros: If she does have an abnormal BRCA1 gene, she can take steps to lower her risk of breast cancer.
Cons: The tests can incite discrimination towards her in the workplace, and having it known she has a risk for breast cancer can severely increase the cost of insurance.
C) Genetic sequencing could affect the frequency of genetic diseases because the test could point out --- I can't finish because I have to go. I'm so sorry, reask the url of this question and ask someone to finish. Have a nice day!

<em>Clastic sedimentary rocks are made up of pieces of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock</em>

Answer:
Human microbiome
Explanation:
The microbiota that aggregates in the human tissues including placenta, skin, lungs, saliva, and seminal fluid is the human microbiome. The microbiota can be virus, bacteria, fungi and protists.
The microbiome present in the human gut helps in digestion and also provides immunity. Microbiomes can be healthy or unhealthy and an imbalance of both can lead to weight gain, high cholesterol and blood sugar. These are the ecological communities that includes symbiotic, commensal and pathogenic microorganisms.
I think the answer is D. Circulatory because this system helps to get the absorbed nutrients throughout the whole body
