Scenario: Kenneth and Catherine Lohmann of the University of North Carolina explored the orientation or direction-finding abilit

ies of loggerhead sea turtle hatchlings under varying magnetic conditions. Hatchlings were placed in a tank of water in a laboratory either in the natural magnetic field of the earth OR in a reversed magnetic field in which north and south were flipped. The researchers then measured the direction that the hatchlings swam. The experiments were carried out in the dark and at night since that is when most newly hatched turtles migrate from their sandy nests into the ocean. After concluding their experiments, the biologists probably:_______. a. shared their data with colleagues to obtain feedback on the work. b. filed away the data in case anyone should ever ask about these experiments and then went on to other types of experiments. c. announced that they had proven a new theory of animal migration.

Answer:

Option A, shared their data with colleagues to obtain feedback on the work.

Explanation:

All researchers prefer to share their findings with their peers or other researchers working in the same field to get their reviews. This step is very essential as it makes the research authentic and removes the flaws that would have otherwise missed by the researcher.  

Peer reviewers also give useful suggestion to further modify one’s research study based on their experiences.  

Hence, option A is correct

Your assignment in biology lab is to design an experiment that would detect whether a substance is breaking down, or digesting,
Elis [28]

Answer: Option B

Explanation: First we should understand the role of enzyme and acid here. Pepsin is an enzyme which will break down proteins into simple monomers (like amino acids). And, acid causes digestion which means it will break down the protein into its respective elements and compounds. Water will act as a control in this experiment.

Option B is correct because it has all three criteria-                                                                                   1. Control [water + protein]                                                                                                               2. With enzyme [egg white + pepsin]                                                                                           3. With acid and enzyme

So this will give us an idea whether pepsin alone is breaking down the protein or digesting it. And there would be difference in test tube B and C. So this will clear the difference.

Option A is incorrect because it has not mentioned any different test tube for checking what happened with the protein. And, Option C is incorrect because mass of egg white will remain same after digestion also.

What is the relationship between CO2 and O2 for urchins?
Vedmedyk [2.9K]

Answer:

Sea urchins have a unique relationship of oxygen and carbon-di-oxide.

Explanation:

Sea Urchins spread oxygen in a unique way. They take in oxygen by staying inside water. Oxygen enters the body through their gills and tubed feet. CO2, which is waste is released through the anus. They get oxygen only through diffusion, i.e. diffusion of oxygen into the organism. Oxygen diffuses in body through the canals and carbon dioxide diffuses back into the canals. Urchins also have the capability to cope up with rising CO2 levels in the sea.

In the pedigree that is shown, which represents Irene's allele combination?
Greeley [361]

The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is X^{H} X^{H} .

Which populations would benefit the most from the presence of decomposers?
Dafna11 [192]
I'm guessing there was answer choices to this problem? regardless I think I know the answer to it. Plant populations would benefit the most of the presence of decomposers due to the fact that decomposers release nutrients into the soil when they break down things.<span />
