1) Since plants are a renewable resource and oil is not, we will eventually run out of the materials needed to make traditional plastic, but we will not run out of what we need to make plant-based plastic.
2) Farming has a much lower carbon footprint than oil extraction and processing does.
3) Plant-based plastic can be biodegradable.
Answer:
Answer is C. By changing the shape of protein.
Explanation:
The site where the substrate binds and the chemical reaction take place is known as the active site.
Note that , if there is changes in the pH, it can affect the active site of the amino acid residue which usually have acidic or basic properties that is important for catalysis, thereby making it hard for substrate to bind.
Complete question:
True or False: The reason that the nail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis.
Answer:
False
Explanation:
Nails are composed of the lamina, which is a smooth, shiny, translucent, and keratinized structure. The nails are born the nail matrix. The newly formed nail slice along the mail bed, which is the plane surface under the nails.
The nail bed places under the nail and is composed of a thin epithelium, with no granulous stratum, and a few layers of parakeratotic cells attached to the nail.
The nail matrix and nail bed have melanocytes. Half of the melanocytes of the matrix produce melanin, while melanocytes of the nail bed are inactive.
The nail bed is laying over many small vessels that nourish it and provides a pink color to the nails.
I think the correct answer from the choices listed above is the last option. The control group to be used to test the hypothesis would be the swallows with average-length tails. A control group <span>is defined as the </span>group<span> in an experiment or study that does not receive treatment by the researchers.</span>
We presented with several statements after the question. Only one of these statements are correct.
DNA replication is the process in which a single strand of DNA, acting as the parent strand, forms two new strands of DNA. DNA transcription is the process of copying the information of the DNA strand and delivering this information into a strand of mRNA. These processes may sound similar, but there are key differences. We must look at the building blocks of DNA and RNA. Both structures are composed of four different bases, however, only three of these bases are shared between structures and they each have a unique fourth base. In DNA, the fourth base is thymine and it is uracil in RNA. We already established that DNA replication forms new strands of DNA, which would use thymine by default. DNA transcription results in formation of mRNA which would therefore use uracil.
The correct statement from the choices provided is the following:
Thymine is used in replication while uracil is used in transcription.
