Why is it important to use renewable energy? And why does it help with climate change?
There is no path to protecting the climate without dramatically changing how we produce and use electricity: nearly 40% of US CO2 pollution comes from power plants burning fossil fuels. ... Renewable energy minimizes carbon pollution and has a much lower impact on our environment. And it's having its moment in the sun.
Answer:
Its important because using the fossil fuels is overheating the planet, and were just wasting something we will never get back, and renewable will make the planet cleaner. This will help because it will dis-polute the air and the ozone layer would be fixed and protect us from the suns rays of radiation with no more holes.

Describe the steps of protein synthesis in a eukaryote.
The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.
The second step is translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.
Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.
What is protein synthesis in a eukaryote?The mRNA exits the nucleus and attaches to a ribosome in the second step of translation. Protein synthesis takes place in ribosomes. An amino acid is created for every three nitrogenous bases in the mRNA.
Transfer RNA transports amino acids to the location where proteins are synthesized. We are left with a polypeptide after this procedure.
The primary level of regulation of eukaryotic gene expression is transcription.
Therefore, the process of transcription involves an enzyme-producing messenger RNA (RNA-polymerase).

Blood type is controlled by the inheritance of any two of the following alleles: IA, IB, or i. IA codes for type A blood. IB codes for Type B blood. Both IA and IB are codominant. The i allele is recessive and will cause Type O blood whenever two copies of the allele are present.
If a mother has Type AB blood (IAIB) and a father has Type O blood (ii), what percentage of their children are likely to have Type A blood?
A. 25%
B. 50%

Answer:
its behavorial adaption
Explanation:
Phycological adaption is less of what they are doing and more of how theybare doing it

Carol and Sam were using the microscope in science class. They used a dropper to put some pond water on their
microscope slide. This is what they saw. "That is something living," said Sam. "I don't think so," said Carol. What do you
think? Explain.
A)
This is not alive. It is not moving or responding.
B)
This sample is made of identical units. It is not alive.
This is a multicellular organism made of cells. It is living
D)
This may have been alive once but not now because it is not moving.
Answer:
Explanation:
I think Sam is right because pond water can be full of impurities which can include many microorganisms such fungi, bacteria, protozoa, etc. For example, there is high possibility that the pond water sample collected by Sam and Carol would contain traces of blue-green algae which is also a living organism as it uses sunlight to prepare its own food.

A)
Carbohydrates
B)
Lipids
Proteins
D)
Nucleic Acids
Answer:
Proteins
Explanation:
Proteins are made up of many repeating units (monomers) of amino acids that are joined by peptide bonds.
Hope this helps :)
The type of molecule is formed from amino acids is - option C. proteins because when connected together by a series of peptide bonds, amino acids form a polypeptide or protein.
Proteins are large macromolecules made of long chains of amino acid monomers, therefore, amino acids are building blocks of proteins. The amino acids are joined by peptide bonds, which form a long chain of polypeptides or proteins.
Required for the functions, structure, and regulation of the body of organisms.There are 20 different amino acidschains of amino acids fold up in complex ways to provide a unique 3D shapeThey also assist with the formation of new molecules by genetic material.Thus, the correct answer is -option C.
