Answer:
plant cell can make its own glucose; an animal cell cannot
Explanation:
Chloroplasts are found in plant cells, but not in animal cells. The purpose of the chloroplast is to make glucose that feed the cell's machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating glucose.
Assume that a DNA double helix contains 100 base pairs (one pair is A-T or C-G) and there are 45 cytosines.
a. How many guanines are there?
b. How many adenines are there?
Cytosine(C) binds with Guanine(C)
Adenine(A) binds with Thymine(T)
a.From here we can deduct that there are the same number of nucleotides of guanine that as cytosine=>G=45 base pairs
b.2A=100-G-C
2A=100-90 2A=10 A=5 base pairs

Answer:
C, is the answer
Explanation:
Option C. sound vibrations are converted to nerve impulses.
What is in the cochlea?The cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact, takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turn around a hollow central pillar, the modiolus.
What is the main function of the cochlea?The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual frequencies of sound.

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.

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.

New seed does not germinate in spite of suitable environment Why?
Answer:
All seeds do not germinate to form new plant because some are not fulfilled with the appropriate amount of nutrients.
Explanation:
A new seed does not germinate in spite of a suitable environment due to a lack of enough nutrients in the soil, a seed may undergo the dormant stage, and too much or little water in the soil.
What is Germination?Germination may be defined as a process through which a seed grows into a seedling.
A lack of nutrients does not deliver enough energy to seed for germination. If the soil has too little water or no water, a seed remains dormant throughout, while if it has too high water, then the seed becomes susceptible to infections.
Under all the above conditions, a seed will germinate into a seedling in spite of a suitable environment.
Therefore, it is well described above.

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.
