The answer is C where the star is found in the sky. If a star is moving toward us, its spectroscopy will be observed at shorter wavelengths, this is called "blueshifted". If the star is moving away from us, the lines will appear in longer wavelengths, and that's called "redshifted".
Sorry for a late response, but I hope this helped.
The variable that researchers manipulate is the independent variable.
The reason for this is because in experiments different manipulations are often introduced. The sole purpose of these manipulations is to see whether they will affect our independent variable and if they will change its value.
The high specific heat capacity of water moderates our climate and allows for life on Earth.
Because it takes a great deal of heat to warm up water, water stays cool longer, and acts as an effective coolant. This is why cool "sea breezes" are welcome on a hot summer's day.
On the contrary, once the water is warmed up, it takes a great deal of heat release to cool the water. This keeps warm winds blowing in off large lakes and oceans in the fall and into the winter, making the temperatures not as frigid as they otherwise could be.
This also accounts for the amounts of precipitation that occur around large lakes, such as the Great Lakes, and oceans.
A force is a push or a pull that acts upon an object as a results of its interaction with another object. ... These two forces are called action and reaction forces and are the subject of Newton's third law of motion
Answer:
A
Explanation:
All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.
The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).
The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.
