Which of the following represents a commensalism relationship?
1 point
Both organisms benefit
Both organisms do not benefit
One benefits and the other is unchanged
One benefits and the other is harmed
Answer:
It would be C, one benefits while the other is unchanged
Explanation:
Commensalism is when an organism, uses another organism to benefit, hwile not bothering its host. One example would be Remora or Barnacles. Remora hang on the edge of sharks eating their left overs, they do not hurt the shark, branacles do the same thing on larger beings like whales.

Question 3
Some globular proteins are water soluble, while all fibrous/membrane proteins are water insoluble.
Which of the following statements BEST explains the reason for these differences?
A
Fibrous proteins have a large number of hydrogen bonds between the amino acids in the polypeptide chains that stabilize their structures, preventing solubility in water. The globular proteins that are water-soluble do not have as many hydrogen bonds between the amino acids in their peptide chains, allowing water solubility.
B
Fibrous proteins are configured in a way that exposes the polar side chains of the amino acids on the surface of the protein, preventing solubility in water. The globular proteins that are water soluble have nonpolar side chains on the surface of the protein, allowing water solubility.
C
Some globular proteins are configured in a way that exposes the polar groups of the amino acids on the surface of the protein, allowing water solubility. Fibrous proteins have nonpolar side chains on the surface of the protein, preventing water solubility.
D
Some globular proteins are composed of more than one polypeptide chain that weakly interacts with one another, allowing water solubility. Fibrous proteins are composed of only one polypeptide chain that tightly folds, preventing water solubility.
Globular proteins are spherical proteins which are water soluble and forms colloid in water.
The best statement which will explain the reason for difference in globular protein and fibrous proteins is statement C.
C. Some globular proteins are configured in a way that exposes the polar groups of the amino acids in the surface of the protein, allowing water solubility.
Fibrous proteins have non polar side chains on the surface of the proteins, preventing water solubility.
Globular proteins are water soluble. Fibrous proteins are not soluble in water.
Amino acids chain prevents folding up so that the chain is not broken and it remains in elongated form. The correct answer is C.

Aquaporins result in a combination of positive charges intracellularly and negative charges extracellularly
What are Aquaporins?
Aquaporin is a group of membrane proteins found in cell membranes and selectively permit water to pass into and out of the cell. Also known as water channels, aquaporins are integral membrane pore proteins. Aquaporins are found in plants, bacteria and animals. They are observed in the vacuolar membranes and plasma membranes. The basic function of most aquaporin is to transport water across cell membranes in response to osmotic gradients created by active solute transport. Aquaporins enable passive transport which means they allow the movement of molecules across a cell without using energy.

Explain why stem cell research is a controversial subject. What are some of the sources for stem cells?
Answer:
Stem cell research is a controversial subject because they are human embryonic stem cell (hESC), and obtaining stem cells involves the destruction of human embryos
Explanation:
The inner cell mass of a 5 to 7-day-old blastocyst can be used to generate pluripotent stem cell lines. Human embryonic stem cell investigation, on the other hand, is morally and politically fraught since it encompasses the killing of human embryos.
What are stem cells?Stem cells are the primary raw material of the body, the cells that give rise to every other cells with specialized functions.
Under the right circumstances, stem cells differentiate to form the most cells known as daughter cells in the body or in a research lab.
Stem cells are mostly found in bone marrow. This is how they divide in order to produce new blood cells.
Once mature, blood cells end up leaving the bone marrow and reach the bloodstream. A small number of immature stem cells enter the bloodstream.
Bone Marrow has long been thought to be the best source of stem cells.
Previously, if a patient required a stem cell transplant but didn't have access to umbilical cord blood stem cells, they earned a bone marrow transplant.
Thus, this is the reason to have stem cell research as a controversial subject.

From the given options, the functions of ATP include:
To power transport across cell membranes.To power the movement of cells.To drive energetically unfavorable reactions.Adenosine Triphosphate (ATP) is defined as the energy molecule that is derived from the metabolic oxidation of glucose.
This ATP is used for a variety of processes which include:
Active transport: It provides the energy that is needed to move materials against a concentration gradient. This leads to the transport of the materials across cell membranes.Movements: Muscle contraction and ciliary movement which brings about movement in cells, requires energy from the hydrolysis of ATP.Thermodynamically unfavorable reaction: This can be driven by the hydrolysis of ATP energy molecule in a cell.Learn more here:

what do you mean by bacteria?
Answer:
Bacteria is a type of micro-organism and is also a prokaryote. These organisms can only be seen using a microscope. Some bacterias are harmful while some are helpful for human daily lives, such as probiotics, and are necessary for life. They have simple cell structures as there is no nucleus or membrane-bound organelles. Bacterias can be found in soil, water, plants, animals, etc. They can cause diseases such as Tuberculosis etc. Due to some diseases being caused by bacterias, doctors prescribe Antibiotics which has the ability to stop the activities in bacterial cell that causes it to lose its protective outer covering and completely stops it from multiplying.
Answer:
Bacteria are among the smallest living things. A single bacterium consists of just one cell, and is called a single-celled, or unicellular organism.
Even though it is just a single cell, it can carry out all seven life processes (movement, respiration, sensitivity, growth, reproduction, excretion and nutrition).

A tech is using the H (flagellar) antigen to serotype a suspected Salmonella species. The results of the serotyping are agglutination with one well that indicates a group of possible serotypes, not one particular serotype. Quality control passed. Why did this occur
Some Salmonella H antigens can occur in multiple strains and serotypes
An antigen (Ag) is any molecule/structure such as, for example, a molecule present on the surface of a pathogenic microorganism, that can be bound by a specific antibody and/or B-cell receptor. The Kauffmann–White classification scheme is a system that was adopted for use in 1934 in order to categorize different serotypes of the bacterial genus Salmonella, based on their somatic-surface antigens. The system is a practical (diagnostic) method based on the variation in the somatic (O) and flagellar (H) antigens present in the cell wall of Salmonella species. In this classification system, 'O' antigens are determined based on oligosaccharides which are associated with lipopolysaccharide, while the "H" antigens are distinguished by the protein content of the Salmonella flagella.Learn more about this topic here:
