DNA is found in the nucleus of eukaryotic cells and the ribosomes, the location where proteins are made, are found out in the cytoplasm of the cell as show below. Explain why this is a problem and how the cell solves this problem.
Answer:
See the answer below
Explanation:
The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.
The problem of transporting the messenger RNA is solved by two features of the cell:
The presence of pores in the nuclear envelopThe presence of transport proteins in the nucleusThe mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP.

A gallon of Moo Milk costs $6.40. $
is the price, in dollars, of an 8-ounce glass of Moo Milk
Answer:
1 gallon = 128 fluid ounces.
So to find the price of an 8 ounce glass of Moo Milk we need to multiply (8/128) x 5.12.

What is a vestigial stucture
A. A type of soul without a membrane-bound nuclear us and without a membrane bound organelles
B. Structures that occur in different species better similar enough to suggest that that the Species had a common ancestor
C. A type of sale that has a membrane-bound nuclear us in a membrane-bound organelles
D. Structures that appear to have no function for the organism but probably had a function in an ancestral organism
Explanation:
Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species.

Dutch elm disease is a disease of elm trees caused by a fungus. The fungus lives off water and nutrients from the tree. It spreads through water-conducting vessels in the
tree. Gum forms within these vessels in response to the fungus, and the tree weakens and dies. Beetles spread the fungus from infected trees. What is the relationship
between the fungus and the elm tree?
A. predator-prey

Based on the the table of rock characteristics and your knowledge of the rock cycle, in which type of
rock (igneous, metamorphic, or sedimentary) would you expect to find bubbles or a smooth, glassy
surface? Why?
HELPPPP ASAP
Answer:
The answer would be igneous. But there are two types of igneous rocks. One is Intrusive, or Plutonic, rocks, and the other is Extrusive. Intrusive rocks crystallize from magma beneath the earth's surface. Extrusive or volcanic rocks crystallize from lava at the earth's surface. Either way, Igneous would have a bubbly, or a smooth, glassy surface.

The biological selection of a particular allele for a trait to be passed to offspring has nothing do with the selection of the allele for another trait. Which of the following supports this statement?

Explanation:
Explain the structure of ribosomes and describe what they do. Then, discuss how ribosomes are different from other organelles.
Explanation:
A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during the process called protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells.
Ribosomes are specialized cell organelles and found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins.
This cell organelle also functions by binding to a messenger ribonucleic acid (mRNA) and decoding the information carried by the nucleotide sequence of the mRNA. The transfer RNAs (tRNAs) comprising amino acids, enter into the ribosome at the acceptor site. Once it gets bind up, it adds amino acid to the growing protein chain on tRNA
A ribosome is a complex of RNA and protein and is, therefore, known as a ribonucleoprotein. It is composed of two subunits – smaller and larger.
The smaller subunit, where the mRNA binds and is decoded and in the larger subunit, the amino acids get added. Both of the subunits contain both protein and ribonucleic acid components.
The two subunits are joined to each other by interactions between the rRNAs in one subunit and proteins in the other subunit.
Ribosomes are located inside the cytosol found in the plant cell and animal cell.
The ribosome structure includes the following:
It is located in two areas of cytoplasm.
Scattered in the cytoplasm.
Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes.
Around 62% of ribosomes are comprised of RNA, while the rest is proteins.
The structure of free and bound ribosomes is similar and is associated with protein synthesis.
Ribosomes Function
The important ribosome function includes:
It assembles amino acid to form proteins that are essential to carry out cellular functions.
The DNA produces mRNA by the process of DNA transcription.
The mRNA is synthesized in the nucleus and transported to the cytoplasm for the process of protein synthesis.
The ribosomal subunits in the cytoplasm are bound around mRNA polymers. The tRNA then synthesizes proteins.
The proteins synthesized in the cytoplasm are utilized in the cytoplasm itself, the proteins synthesized by bound ribosomes are transported outside the cell.
Frequently Asked Questions
What is the function of the ribosome?
Ribosomes are the organelles that help in protein synthesis. Protein is required for many cell activities such as damage repair and other chemical processes.
What is a ribosome composed of?
A ribosome is composed of two subunits:
the small ribosomal subunits- these read the mRNA
the large ribosomal subunits- they form polypeptide chains of amino acids.
How does the ribosome work?
The ribosomal subunits come together and combine with the mRNA during protein synthesis. They bind to the mRNA and start the synthesis of proteins.
What are the two different types of ribosomes?
The two different types of ribosomes include:
70 S-found in prokaryotic cells
80 S-found in eukaryotic cells
How are prokaryotic ribosomes different from eukaryotic ribosomes?
Prokaryotic ribosomes include three individual rRNA molecules and contain the large ribosomal subunit, the 80s.
Eukaryotic ribosomes include four individual rRNA molecules and contain the small ribosomal subunit, the 70s.

Which of the following is evidence that cells no longer respond to external factors and may have turned cancerous?
A. New cells replace old or damaged cells.
B. Cell clumps form, crowding existing cells.
C. Dead cells are shed at a more rapid rate.
D. Dormant cells re-enter an active cell cycle.
Answer:
option C will be the correct answer
Dead cells are shed at a more rapid rate is evidence that cells no longer respond to external factors and may have turned cancerous.
What are the cancer cells?Cancer cells are defined as cells which divide continually, forming solid tumors or flooding the blood with abnormal cells. Cell division is a normal process used by the body for growth and repair.
Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn’t. These cells may form tumors, which are lumps of tissue.

Does light have an effect on carbon dioxide production by plants and animals?
(No Links!! type the answer)
Answer:
Light provides the energy for photosynthetic pig- ments to convert carbon dioxide (CO2) and water into sugars and oxygen. As light intensity increases – until a point – the amount of sugars increases and thus, more energy is available for plant growth and maintenance. ;)
Why is the reduction in chromosomes number important in meiosis?
Explanation:
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.

circle with center at (-3, 7) and radius 8
Explanation:
Centre of the circle ( h,k)=(-3,7)
radius of the circle (r)=8
Equation of the circle is,
(x-h)^2+(y-k)^2=r^2
or,(x+3)^2+(y-7)=8^2
or,x^2+6x+9+y^2-2y+49=64
or,x^2+y^2+6x-2y+58-64=0
or,x^2+y^2+6x-2y-6=0 is the required equation of the circle
