Why is using the presence of chromosomes inside of a cell NOT a reliable method to
determine if the cell is a prokaryote or a eukaryote?
Because both prokaryotic and eukaryotic cells have chromosomes (prokaryotes, and more specifically, bacteria, generally have just one chromosome, but there are some bacteria as well as archaea—which are also prokaryotes—that have multiple chromosomes).
Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic
The nucleus of a eukaryotic cell is bounded by internal membrane, therefore, it is distinctive.
In contrast, the nucleus of a prokaryotic cell lacks internal membrane, hence its nucleus is not distinctive.
Chromosomes are Deoxyribonucleic (DNA) molecules that carry genetic information of a cell or organism.
The chromosomes are present in both the eukaryotic and prokaryotic cells. Chromosomes present in the eukaryotic cells are called eukaryotic chromosomes while chromosomes present in the prokaryotic cells are called prokaryotic chromosomes.
Since the chromosomes are DNA molecules present in both the prokaryotic and eukaryotic cells, it is not a reliable method to determine if a cell is prokaryotic or eukaryotic

is a human is apart of earth's lithosphere true or false
Humans utilize the lithosphere for their habitat, but humans are not a part of it. So the statement is false.
What is lithosphere?The outer, solid layer of the Earth is called the lithosphere. The lithosphere gradually thickens over time as the Earth's convection system's cooling surface layer. It is broken up into quite sturdy plates or parts that move independently of one another. Plate tectonics is the term used to describe these lithospheric processes. The crust and highest layer of the mantle are both included in the lithosphere, which floats atop the weaker asthenosphere. The lithosphere comes in two varieties:
The oceanic crust is connected to the oceanic lithosphere.The Continental crust is connected to the Continental lithosphere.When compared to the continental lithosphere, which is generally 150 km thick and is made up of 50 km of crust and 100 km or more of the topmost mantle, the oceanic lithosphere is typically 50–100 km thick (although is not thicker than the crust under the mid-ocean ridges).
The oceanic lithosphere is denser than the continental lithosphere, whose mantle is connected with crust comprised of felsic rocks, and is mostly composed of the mafic crust and ultramafic mantle.
Therefore, the statement is false.
