D. Distant galaxies move progressively farther away from Earth.
The glaciers are visible because Ice floats when it freezes .This particularly helpful to life as it insulates the water below and is home to a variety of animals. Which is property of water is the reason that we can see icebergs float
Answer:
Water is denser as a liquid than as a solid.
Explanation:
The property of water that makes icebergs float on is due to the fact that water as a liquid is denser than as a solid.
According to the rules of floatation, a less dense substance will always float on a denser liquid because a body will always displace its own weight when placed in a liquid. At room temperature, water as a liquid has a density of 1 g/cm3 but if the same water forms ice, the density would be 0.92 g/cm3. Hence, when ice is placed on water, it will float on it.
How are rainbows made?
Answer:
Explanation:
The sun makes rainbows when white sunlight passes through rain drops. The raindrops act like tiny prisms. They bend the different colors in white light, so the light spreads out into a band of colors that can be reflected back to you as a rainbow.
conduction of heart beat
Answer:
Explanation:
The cardiac conduction system are specialized cardiac muscle cell that are located in the walls of the heart and sends signals to the heart muscle. These signals cause the heart to contract. The main components of this system are AV node, bundle of His, SA node, bundle branches, and the Purkinje fibers.
Even though sunlight looks white, what is it really made up of?
Answer:
White light means your not missing any of the visible color spectrum, so all the colors.

An egg is protected by its outer shell. However, the shell also allows moisture and air to pass through. Which cell structure performs a similar function? A. cell membrane B. cytoplasm C. nucleus D. vacuole
Answer:
A. Cell membrane
Explanation:
The cell is the basic unit of the living organisms. The cell consists of the various cell organelles like nucleus, mitochondria and Golgi. The cell membrane covers the cell boundary.
The outer shell protects the egg and allows the exchange of moisture. The plasma membrane performs the similar functions ad allows the transport of some selected particles only.
Thus, the correct answer is option (A).
Answer:
A. cell membrane

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?
A.silent
B.missense
C.nonsense
D.insertion
Answer:
A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.
Explanation:
In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.
In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
For the other options:
Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.Answer:
Silent

1. During mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes?
Mitosis is the cell division which occurs in all types of cells in the body. This results into formation of daughter cells with same set of genetic material as the parent cell.
What is Mitosis?
Mitosis is a type of cell division which occurs in all types of cells. This division is also called as Equational division as the genetic content remains constant from the parents to offspring. This process results into formation of two daughter cells which are similar to the parent cell.
In mitosis, a cell divides to form two identical daughter cells with same genetic material. It is important that the daughter cells have a copy of every chromosome in their nucleuc, so the process involves copying of the chromosomes first and then carefully separating the chromosomes copies to give each new cell a full set of genetic material.
