The process our body continually uses to help maintain homeostasis for our blood sugar levels is an example of Homeostasis Mechanism.
The correct answer choice is option c
What is meant by homeostasis?Homeostasis can simply be defined as the regulation, adjustment and maintenance of the internal environment of an organism.
Homeostatic mechanism involves three main parts:
The receptorThe effectorControl centerHomeostasis mechanism help to raise the blood glucose levels when its below normal and also lowers the blood glucose levels when it is too high.
This is achieved by the hormones; insulin and glucagon.
So therefore, the process by which our body continually uses homeostasis to maintain our blood sugar levels is an example of Homeostasis Mechanism.

Where does protein production start and finish?
Answer:
In prokaryotes, it occurs in the cytoplasm. In eukaryotes, it initially occurs in the nucleus to create a transcript (mRNA) of the coding region of the DNA. The transcript leaves the nucleus and reaches the ribosomes for translation into a protein molecule with a specific sequence of amino acids.

1. Consider how lettuce or spinach placed in water becomes firm and crisp. Use what you have learned about cell membranes to explain this observation. Be sure to include homeostasis in your explanation.
Lettuce or spinach becomes crunchy in water because it draws water back into its vacuoles.
How do they get crispier when you add water?Plant cells will be made up of an outer wall that is rigid in addition to the cell membrane, and will also have a vacuole in its center filled with water that is responsible for keeping the cell swollen. So when adding lettuce or spinach to a medium full of water, the water will enter the cell to maintain homeostasis in the medium, since there will be more water outside than inside.
This will then cause the cell to become swollen and firm, making the lettuce or spinach firm and crisp again.
Therefore, we can confirm that lettuce or spinach becomes crunchy in water because it draws water back into its vacuoles.

The time period T is the time it takes one wavelength or two consecutive troughs (or crests or another wave reference factor) to bypass by using a fixed position.
A wave is a propagating dynamic disturbance of 1 or greater quantities. Waves can be periodic, in which case those quantities oscillate again and again about an equilibrium fee at a few frequencies. A wave is a disturbance in a medium that carries energy without a net motion of particles. it is able to take the shape of elastic deformation, a version of pressure, electric powered or magnetic intensity, electric ability, or temperature.

What is translation ?Translation is the formation of protein from m-RNA. Similar to mRNA synthesis, protein synthesis can be broken down into three stages: initiation, elongation, and termination.
The first stage of protein synthesis is the formation of an initiating complex.This complex in E. coli is composed of the short 30S ribosome, the mRNA template, three initiation factors (IFs; IF-1, IF-2, and IF-3), and a particular initiator tRNA known as tRNA Metf.Met-tRNAThe initiator tRNA, or I is a particular tRNA that carries the amino acid methionine.Instead of looking for the Shine-Dalgarno sequence, the eukaryotic initiation complex looks for the 5′ cap of the eukaryotic mRNA.
