Why would overfishing cause a starfish outbreak

Answers

Answer:

quote, "Cause of crown of thorns starfish outbreak

These outbreaks may be a result of overfishing of the crown-of-thorns starfish's primary predator, the giant triton or they may be a natural phenomenon. These starfish are known to be more successful at preying on large swaths of coral reefs when the corals are already stressed."

What is structure and function?

The structure of a biological organism refers to the arrangement or organization of parts to form an organ, system, or living thing.

The structure of an organism determines the adaptation and survival of that organism in its natural environment because these structures perform functions that are germane to its survival.

Some common examples of structures in living organisms and their functions are as follows:

Radula in snails - for feedingHorns - for protection against intrudersClaws - for holding on to prey

Therefore, the statement that best represents how structure relates to function is as follows: longer legs and different hip bones let modern humans walk upright.

Please answer the following questions based on the titration curve:
1. From the plot, determine the number and types of titratable groups for the unknown amino acid.
2. Determine best you can the experimental pKa values for each titratable group from the plot
3. Determine best you can the molecular weight of your unknown amino acid from data obtained from
your plot.
4. Calculate the isoelectric point of your sample. a) What is the definition of isoelectric point? b)
Where would you find the isoelectric point on a titration curve?
5. What is the identity of your unknown amino acid? Justify your conclusion by comparing the
observed molecular weight and pKa values to those for all of the amino acid

Answers

Titration is a useful tool in the determination of amino acid side chains and the ionizable groups. There are two titratable groups for the unknown amino acid. These are α-COOH and α-NH₃⁺. The experimental pKa values for the groups are- pK₁ = 2.35 for α-COOH and pK₂ = 9.78 for α-NH₃⁺.

What is Isoelectric point?

Amino acids are the organic compounds that contain both amino and carboxylic acid functional groups. Isoelectric point (pI) is the pH at which the net charge on an amino acid is zero. The isoelectric point of the given amino acid can be calculated by the formula:

pI = (pK1+pK2)/2 = (2.35+9.78)/2 = 6.065

Isoelectric point will be in the middle part of the curve in the buffer region. Buffer region is the section of curve between the initial point and the equivalence point.

The unknown acid would be glycine. The curve gas two dissociation steps- loss of H⁺ from the carboxyl group at low pKa value and gain of H⁺ by the amino group at high pKa value.

Answers

Answer:

resolution

Explanation:

Resolution is the ability of the lenses in the microscope to clearly distinguish between two adjacent objects as distinct and separate.

A compound light microscope has a maximum resolution of 0.2 µm, which means it can clearly distinguish between two adjacent, but distinct objects. Any objects closer than 0.2µm will be seen as 1 object.

Antibodies are a Y-shaped protein that are secreted by the immune system to identify and neutralize pathogens in vertebrates. Antibodies have an antigen binding site that allows for binding to surface proteins found on a specific pathogen, called antigens. All cells have identifying protein markers on the surface that specify whether it’s foreign or a part of the same organism. Some pathogens have the ability to alter their antigens, preventing antibodies from identifying them.
Which of the following arguments is BEST supported by this information?
A
The shape of an antigen allows for antibodies to identify the cell, indicating that the shape of the protein provides specificity.
B
The binding site of an antibody can be altered to accommodate more pathogens.
C
Antibodies must be a complex protein because it is only found in vertebrates.

Pathogens can release their own antibodies to fight off host immune system.

Imagine you are exploring a new planet and discover a plant-like organism which does not have chloroplasts. Which of the
following statements would be TRUE about the organism?

O It may not be capable of photosynthesis.
O It still has all the appropriate organelles to photosynthesize like an earth-based plant.
O It uses different wavelengths to photosynthesize than earth-based plants.
O It does not store energy as glucose

Answers

Chlorophyll, a pigment found in chloroplasts, is what allows plants to prepare food through photosynthesis. There would not have been any plant life if there were no chloroplasts.

Chlorophyll, which is found in chloroplasts, traps light and aids in photosynthesis. Without chlorophyll, there would be no food, which would mean no life. We wouldn't have food if plants lacked chloroplasts since they couldn't use the sun's energy to stay alive. On the other hand, mammals would not have enough cellular energy and would not be able to exist without mitochondria. The process of photosynthesis is carried out by some plants that lack chloroplasts.

Two test tubes labeled A and B
We set up another experiment in which we added the following enzymes:
Test Tube A = cellulase and Test Tube B = amylase. When the substrate
from the enzyme lab is added what would you expect to see happen in
each tube?

Answers

An enzyme-catalyzed reaction initially progresses at a faster pace as substrate concentration rises. This rise in rate of a reaction levels off as the substrate saturates the enzyme molecules.

An enzyme's concentration increases along with the speed of an enzyme-catalyzed process. The breakdown of the polysaccharide starch (amylose) into the disaccharide maltose is catalyzed by the enzyme amylase. Although it is easily abundant in saliva, obtaining high amounts might be uncomfortable. It is found throughout plant tissues, but it is most prevalent in seed, where that might play a role in starting the conversion of starch that has been stored into the much-needed glucose in enzyme-catalyzed process. The most prevalent organic polymer on earth is cellulose, a polysaccharide made up of a linear chain of 1,4-linked d-glucose subunits with such a degree of polymerization ranging from few hundreds to over ten thousand. An enzyme-catalyzed process is created when an enzyme binds to its substrate. This complex provides certain ions or chemicals groups that really establish chemical bond with molecule as a crucial stage of the reaction process, lowering the energy of activation and promoting its quick progression.
