1.Explain what makes a scientific experiment reliable. Be sure to include at least three reasons to support your answer.

2.During research, why is it important to use peer reviewed evidence when collecting background information during a scientific investigation?

Answers

Answer:

1:When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and get very similar results then those results are said to be reliable.Reliability is measured by a percentage if you get exactly the same results every

time then they are 100% reliable.

2.The peer reviewer determines whether the introduction provides sufficient background information on the research topic, and ensures that the research question and hypothesis are clearly identifiable.

The behavior of allosteric enzymes a. does not play any role in feedback inhibition in metabolic pathways b. is strongly dependent on the presence of metal ions c. is related to their ability to hydrolyze themselves d. depends on changes in their quaternary structure on binding of substrates or inhibitors

Answers

Answer:

The correct answer is d

Explanation:

Allosteric enzymes have multiple binding sites to different ligands called allosteric sites (different from the active site), these ligands can modify their kinetic properties. They are generally made up of more than one polypeptide chain, and have a quaternary structure, an enzyme with a quaternary structure can bind more than one substrate molecule. An allosteric enzyme is an enzyme whose activity is regulated by an allosteric center, which is a site, other than the active center of the enzyme, to which a regulator (called an allosteric regulator) binds in a reversible and non-covalent manner. The binding of this regulator modifies the three-dimensional structure of the enzyme and affects the configuration of the active site, thus increasing or decreasing its activity, depending on the case. The allosteric sites present in regulatory enzymes is where allosteric effectors or inhibitors are attached, causing a conformational change in the substrate binding site or catalytic site, thus regulating enzyme activity.

Answer:

d. depends on changes in their quaternary structure on binding of substrates or inhibitors

Explanation:

Allosteric enzymes are oligomeric proteins composed of subunits or polypeptidic chains. They have a quaternary structure -many subunits and active sites- and express two states, R and T. Both states establish an equilibrium, with or without a joint ligand.

When the transition from one state to the other occurs, symmetry is conserved, but the affinity of a site to a ligand is altered. When a substrate joins one of the sites, it affects other binding sites.

Allosteric enzymes can change their conformation, exhibiting active and inactive conformations as a result of substrate binding at the activated center and regulatory molecules at other binding sites -allosteric centers-.

Why is The sun is the ultimate source of energy
for all living organisms.'

Answers

The answer is: The sun is called the ultimate source of energy because it is the source of almost all energies of the earth. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.

Answer:

"Sun is the ultimate energy source for all living organisms."

✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.

✴Secondly, sunlight is a good source of Vitamin-D.

Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.

✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.

B)how Trichoplax adhaerens eats by engulfing its food
CAN I GET ANSWERS ASAP PLS

Answers

Answer:

D - How trichoplax adhaerens eats by engulfing it's food

Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D. It is a process by which the cells engulf the food that is coming from the outside of the cell.

What is phagocytosis?

The cell has many organelles, such as the lysosome, vacuole, cell nucleus, etc., but each organelle has a special function, and one organelle cannot take over the function of another organelle. The lysosomes have a very unique and acidic environment that destroys the organelles, such as old organelles, and kills viruses, etc.

When outside food particles or pathogens enter the cell, they enter as a vacuole, and the cell transports them from the outside to the inside through a variety of processes. The cell then eats them, a process known as phagocytosis, and if it is a virus, the lysosome degrades it.

Hence, Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D.

The evolutionary history and development of whales has been hotly debated. Recently there has been a major shift in our understanding of the processes used to detail whale evolution. This indicates that: Group of answer choices A) Aspects of evolution are constantly being challenged and explored in light of new evidence. B) Gaps in the fossil records will never allow us to fully understand evolution. C) Scientists studying evolution typically present ideas with very little evidence, leaving it to others to find proof of their ideas. D) Much of the science of evolution is based on speculation that can easily be changed when scientists think of new ideas.

Answers

Answer:

Aspects of evolution are constantly being challenged and explored in light of new evidence

Explanation:

The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''

Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.

For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.
