Eukaryotic ribosomes exist freely floating in the _______ and membrane-bound.
In peptide synthesis, after an amino acid has been added to the polypeptide chain, the empty _______ exits the ribosome.
Answers
2. cytoplasm
3. transfer RNA
Answer:
transcribed
cytoplasm
tRNA
Ribosomes are located in the cytoplasm, the fluid material that comprises the cell. In prokaryotes, ribosomes freely float in the cytoplasm. In eukaryotes, ribosomes can be both freely floating and membrane-bound. The ribosome's role in gene expression is to synthesize proteins based on the instructions provided by mRNA. The mRNA strand is made from the cell's DNA and tells the ribosome how to construct the cell's necessary proteins.
The ribosome is essential for protein synthesis, so it is part of translation and not transcription. The ribosome reads instructions from mRNA and "translates" them into proteins.
Prokaryotes and eukaryotes have some major structural differences, so the details of protein synthesis differ between these two types of organisms as well. Prokaryotic organisms such as bacteria do not have a cell nucleus, so the cell's DNA floats freely in the cell. In eukaryotic organisms such as humans, the cell's DNA is located in the nucleus, while the ribosome is located in the cytoplasm.
Eukaryotic ribosomes are also larger and more complex than prokaryotic ribosomes.
Transfer RNA, or tRNA, provides a physical link between the codons of the mRNA and the amino acids to be added to the polypeptide chain. Specific tRNA molecules are bound to specific amino acids, and tRNA that is complementary to the mRNA codon enters the ribosome and transfers its amino acid to the growing polypeptide chain.
Ribosomal RNA, or rRNA, is an important component of the ribosome. Both eukaryotic and prokaryotic ribosomes contain rRNA. rRNA and proteins together carry out the functions of the ribosome.
If there are no ribosomes present in the cell, proteins cannot be made. Without protein synthesis, cells cannot accomplish their necessary functions, and the organism will die.

words that have the same sound but different spellings and meaning
Answers
Answer:
words that have the same sound but different spellings and meaning
Explanation:
"Homophones" are words that are pronounced in the same manner, yet are spelled differently. They also have different meanings. For example, the word "see" and "sea" are spelled differently. However, they are pronounced in the same way. "See" refers to the act of discerning something visually while "sea" refers to the body of salt water.
Here are other examples of homonyms:

B. Trees remove carbon dioxide and add oxygen the atmosphere
C. Trees filter particulates and polluting gases from the atmosphere.
D. All of the above
Answers
Answer:
D
Explanation:
in any test or quiz that there is an answer that says all of the above its always all the above
The statement that explains how trees help conserve energy and reduce pollution in cities are three shade buildings that reduce the use of derived from fossil fuels, remove carbon dioxide, and they filter particulates and pollute gases from the atmosphere. The correct option is D, all of the above.
What is pollution?Pollution is the unwanted things that pollute or waste the environment and harm the earth and living beings. If trees are planted in large numbers, the carbon dioxide gas in the atmosphere is absorbed by plants for photosynthesis. Plants absorb carbon dioxide, which is released when fossil fuels are burned, and hence contribute to pollution reduction.
Every year, trees absorb one-third of all world emissions. Particles, odors, and harmful If trees are planted in large numbers, the carbon dioxide gas in the atmosphere is absorbed by plants for photosynthesis.

Follow steps 1-6 on pp. 50-51 of your lab manual for this exercise. What is the amino acid sequence for the mRNA strand that you drew in step 6
Answers
Answer:
Amino acid sequence:
Serine (Ser)- Leucine (Leu)- Glycine (Gly)- Arginine (Arg)- Threonine (The)
Explanation:
This question is related to gene expression, which involves the transcription of DNA sequence into mRNA, and the subsequent translation of mRNA into amino acid sequence (protein).
- The transcription of a DNA sequence into mRNA is based on complementary base pairing rule i.e. A-T, G-C. Based on this pairing rule, the DNA sequence (AGC AAT CCG TCT TGG) will be transcribed into UCG UUA GGC AGA ACC.
- Using the genetic code which contains codons that encode amino acids, the mRNA sequence (UCG UUA GGC AGA ACC) will be translated into the amino acid sequence as follows: Serine (Ser)- Leucine (Leu)- Glycine (Gly)- Arginine (Arg)- Threonine (The).

Explain the process of the Greenhouse Effect. How does it happen?
Answers
Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).
The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.
Enhanced greenhouse effect
The problem we now face is that human activities – particularly burning fossil fuels (coal, oil and natural gas), agriculture and land clearing – are increasing the concentrations of greenhouse gases. This is the enhanced greenhouse effect, which is contributing to warming of the Earth. Greenhouse effect
Step 1: Solar radiation reaches the Earth's atmosphere - some of this is reflected back into space.
Step 2: The rest of the sun's energy is absorbed by the land and the oceans, heating the Earth.
Step 3: Heat radiates from Earth towards space.
Step 4: Some of this heat is trapped by greenhouse gases in the atmosphere, keeping the Earth warm enough to sustain life.
Step 5: Human activities such as burning fossil fuels, agriculture and land clearing are increasing the amount of greenhouse gases released into the atmosphere.
Step 6: This is trapping extra heat, and causing the Earth's temperature to rise.
Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.

What is cell?"A cell is the structural and functional unit of life."Each organisms are made of one or more number of cells.A cell has many organelles that performs specific functions.What is common cold?"Common cold is a viral infection of throat and nose."What is virus?"A virus is a microbe which we cannot see directly through our eyes.""It is a connecting link between living and non-living things."The virus has either DNA or RNA as their genetic material.They cannot replicate on their own, they require a host for their growth.The virus first injects its genetic material, which gets incorporated into the host genome. The host will now also replicate virus DNA along with its own. As the replication is completed the replicated material will burst out from the cell, ready to infect the other cell as well and continuing the cycle.What do you mean by replicate?"It means makings its duplicate copy."Hence, the correct option is D. Viruses replicate inside a cell and then burst out of the cell.
