Because they are marine animals, sea urchins cannot survive in freshwater. They are widespread, from the sea's surface to its depths. The species that we'll probably work with in the lab are found in intertidal or shallow subtidal zones.

In public aquariums, sea urchins are utilized as indicator species to assess the system's health. Due to their high water sensitivity, this is. When the water is contaminated, sea urchins are one of the first to exhibit indications of stress, such as dropping & falling spines.

Additionally, they have been observed consuming carrion, sponges, sea stars, mussels, sea cucumbers, and polychaete worms. Using their mouths to grip and bite, sea urchins consume food.

In order to form 3 peptide bonds, 3 molecules of water are produced. This is because each peptide bond formation involves the removal of one molecule of water as the amino acids are linked together through a condensation reaction. Therefore, the number of peptide bonds formed is directly proportional to the number of water molecules produced.

Peptide bonds are covalent bonds that develop during the synthesis of proteins between the amino group (-NH2) of one amino acid and the carboxyl group (-COOH) of another amino acid. A covalent link between the carbon atom of the carboxyl group and the nitrogen atom of the amino group is created as a result of the dehydration synthesis process, which removes a molecule of water from the amino acids. The development of proteins, which are made up of lengthy chains of amino acids joined by peptide bonds, depends on peptide bonds. These bonds control the three-dimensional structure and biological activity of proteins. Additionally crucial for the creation of other biomolecules including enzymes, hormones.

Answer:Ribosomes are the cellular structures responsible for protein synthesis. When viewed through an electron microscope, ribosomes appear either as clusters (polyribosomes) or single, tiny dots that float freely in the cytoplasm. They may be attached to the cytoplasmic side of the plasma membrane or the cytoplasmic side of the endoplasmic reticulum and the outer membrane of the nuclear envelope. Electron microscopy has shown us that ribosomes, which are large complexes of protein and RNA, consist of two subunits, aptly called large and small (Figure 1). Ribosomes receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA). The mRNA travels to the ribosomes, which translate the code provided by the sequence of the nitrogenous bases in the mRNA into a specific order of amino acids in a protein. Amino acids are the building blocks of proteins.

Because proteins synthesis is an essential function of all cells, ribosomes are found in practically every cell. Ribosomes are particularly abundant in cells that synthesize large amounts of protein. For example, the pancreas is responsible for creating several digestive enzymes and the cells that produce these enzymes contain many ribosomes. Thus, we see another example of form following function.

Mitochondria

Mitochondria (singular = mitochondrion) are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule. ATP represents the short-term stored energy of the cell. Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients. In mitochondria, this process uses oxygen and produces carbon dioxide as a waste product. In fact, the carbon dioxide that you exhale with every breath comes from the cellular reactions that produce carbon dioxide as a byproduct.

In keeping with our theme of form following function, it is important to point out that muscle cells have a very high concentration of mitochondria that produce ATP. Your muscle cells need a lot of energy to keep your body moving. When your cells don’t get enough oxygen, they do not make a lot of ATP. Instead, the small amount of ATP they make in the absence of oxygen is accompanied by the production of lactic acid.

This transmission electron micrograph of a mitochondrion shows an oval outer membrane and an inner membrane with many folds called cristae. Inside the inner membrane is a space called the mitochondrial matrix.

Figure 2. This electron micrograph shows a mitochondrion as viewed with a transmission electron microscope. This organelle has an outer membrane and an inner membrane. The inner membrane contains folds, called cristae, which increase its surface area. The space between the two membranes is called the intermembrane space, and the space inside the inner membrane is called the mitochondrial matrix. ATP synthesis takes place on the inner membrane. (credit: modification of work by Matthew Britton; scale-bar data from Matt Russell)

Mitochondria are oval-shaped, double membrane organelles (Figure 2) that have their own DNA and ribosomes (we’ll talk about these later!). Each membrane is a phospholipid bilayer embedded with proteins. The inner layer has folds called cristae. The area surrounded by the folds is called the mitochondrial matrix. The cristae and the matrix have different roles in cellular respiration.

Peroxisomes

Peroxisomes are small, round organelles enclosed by single membranes. They carry out oxidation reactions that break down fatty acids and amino acids. They also detoxify many poisons that may enter the body. Many of these oxidation reactions release hydrogen peroxide, H2O2, which would be damaging to cells; however, when these reactions are confined to peroxisomes, enzymes safely break down the H2O2 into oxygen and water. For example, alcohol is detoxified by peroxisomes in liver cells. Glyoxysomes, which are specialized peroxisomes in plants, are responsible for converting stored fats into sugars.

Benedict's solution is a chemical reagent that is used to test for the presence of reducing sugars, such as glucose, in a given sample. However, Benedict's solution is not capable of distinguishing between glucose and fructose. This is because Benedict's solution can only react with acidic carbohydrates and not neutral carbohydrates.

Benedict's solution is made up of copper(II) sulfate, sodium carbonate, and sodium citrate in water. When heated in the presence of a reducing sugar, the solution turns from blue to green, yellow, orange, or even red, depending on the amount of reducing sugar present. The color change is due to the formation of a precipitate of red copper(I) oxide.
Glucose and fructose are both monosaccharide sugars that have the same molecular formula (C6H12O6) but differ in their structure. Glucose has an aldehyde group (-CHO) on its first carbon atom, whereas fructose has a ketone group (-CO-) on its second carbon atom.
Benedict's solution can only react with reducing sugars that have a free aldehyde or ketone group. Both glucose and fructose have a free carbonyl group, which means that they are reducing sugars and will react with Benedict's solution. However, since Benedict's solution cannot distinguish between acidic and neutral carbohydrates, it cannot differentiate between glucose and fructose, which are both neutral carbohydrates.
In conclusion, Benedict's solution can be used to test for the presence of reducing sugars, including glucose and fructose, but it cannot distinguish between the two since they are both neutral carbohydrates.

The correct order of events for B cell activation is as follows: 1. B cell phagocytoses antigen and displays it on MHC II receptor, 2. T Helper Cell (TH2) binds to antigen on MHC II on B cell surface, 3. T Helper Cell (TH2) releases cytokines that activate B cell,4. B cell proliferates to produce plasma cells and memory B cells,5. Plasma cells secrete antibodies, 6. Antibodies bind pathogens.

1. B cell phagocytoses antigen and displays it on MHC II receptor: B cells have surface receptors called B cell receptors (BCRs) that can recognize specific antigens. When a B cell encounters an antigen that matches its BCR, it engulfs and internalizes the antigen through a process called phagocytosis.

2. T Helper Cell (TH2) binds to antigen on MHC II on B cell surface: T helper cells, particularly a subset known as TH2 cells, play a critical role in activating B cells.

3. T Helper Cell (TH2) releases cytokines that activate B cell: After the TH2 cell recognizes the antigen on the B cell, it releases cytokines such as interleukin-4 (IL-4) and interleukin-5 (IL-5).

4. B cell proliferates to produce plasma cells and memory B cells: In response to the cytokines released by the TH2 cell, the activated B cell undergoes clonal expansion, leading to the generation of a large population of identical B cells.

5. Plasma cells secrete antibodies: Plasma cells are highly specialized for antibody production. They secrete large quantities of antibodies, also known as immunoglobulins (Igs), into the bloodstream.
