Thinking back to yesterday's reading, what type of ecological relationship is it? What are the bacteria doing for us? How do they avoid being killed off by our immune system? Gut Bacteria Reading

Answers

Answer:

The relationship between gut bacteria and we the host is a mutualistic relationship. This is a form of relationship where both we and the bacteria benefit from the bacteria living in our gut.

They help us in our digestion process to break down some food particles into their basic units, some of which we would not be able to do without them. They also help to keep the gut’s surface intact, provide vitamins, and fight off other harmful bacteria.

Bacteria use immunity genes to neutralize toxins and protect themselves against been destroyed by our immune system by copying our immune resistance code, and using this code to make their outer membrane.

Be able to scale production up in an economical way

Use microbes to make oil?

Explanation:

In order for biofuels to become viable option the industry need to Use feedstocks that convert most/all of the plant to energy, not just kernels, Change the public view on biofuels, Be able to scale production up in an economical way, and Use microbes to make oil because biofuels are fuels produced from organic matter or living matter such as plant material and animal wastes which is use for transportation majorly.

In order for biofuel to become viable options, there should be increase in production in a way that is affordable,cheap and safe, use feedstocks that convert plants and animals remains since plants and animal remains are used for it's production and also some microbes are of economic importance's that help to breakdown or decompose plants and animals remains to make oil which is called biodesel use for transportation.

A. brown algae
B. diatoms
C. dinoflagellates
D. ciliates

Answers

Answer:

Pretty sure it's C.

Ciliates are the groups of organisms which include the protists that reside within the cells of corals. Thus, the correct option is D.

What are Ciliates?

The ciliates are a group of protists which are characterized by the presence of hair-like organelles called as cilia on their membrane which are identical in structure to the eukaryotic flagella, however these are in general shorter and present in much larger numbers than that of flagella, and also with a different undulating pattern than flagella.

Cilia occur in all members of the group and are variously used in the activities such as swimming, crawling, attachment, feeding, and sensation.

Therefore, the correct option is D.

A scientist wishes to test a new type of adhesive to connect two metals together. He tests his hypothesis that the new adhesive works better than existing treatments by applying the adhesive to the two metals, sticking them together and seeing how long they stick. He performs this test on his new adhesive, records the time and then reports the results. What is missing from his experimental design?

Answers

Answer and Explanation:

The scientific method is a research method used to produce knowledge. It consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility (the capability of reproducing the experiment in any other place by any researcher) and refutability (susceptibility to be refused).

There are different steps to follow in a scientific method:

Definition and problem statement. The question for which there is not an answer yet.

Hypothesis formulation.  

Data collection and analysis. This step involves testing the observations.

Results

Verification of the hypothesis. This step involves the acceptance or rejection of the working hypothesis.

Conclusions and Discussion.  

In the exposed example:

Let us imagine that the scientist only wants to evaluate the performance of the new adhesive connecting only two previously determined metals: Metal A and metal B. Let us also assume that there is only one exhisting adhesive, apart from the new one that is being tested. Finally, we might also assume that he has already done bibliographic research to know better about the requirements for adhering metals and the properties of the adhesive material needed to do so. The problem might have been related to the need of getting a better adhesive.  

Hypothesis: "the new adhesive works better than existing treatments"Treatment: applying the adhesive to the two metals, sticking them together and seeing how long they stickData collection and analysis: He performs this test on his new adhesive, records the timeResults obtention and report

The scientist did not perform the experiment with the existing adhesive. The scientist did not compare the performance of the previously existing adhesive to the new one.

The scientist should have performed the experiment with two treatment groups:

Treatment Group one: applying the existing adhesive to the metals A and B, sticking them together and seeing how long they stickTreatment Group two: applying the new adhesive to the metals A and B, sticking them together and seeing how long they stick

The scientist also should have repeated the treatment at least two or three times for each group.

Finally, the scientist should have compared results between the performance of the two adhesives before reporting them.

why did albumin not diffuse into the dialysate?

Answers

Answer:

Albumin provides the body with the protein needed to both maintain growth and repair tissues. It can also help with fluid removal during the dialysis treatment. If your albumin level is good, fluid will move more easily from swollen tissues into the blood, where it can then be removed by the dialyzer.

Due to the large size, the albumin does not get diffuse into the dialysate.  

• The size of albumin is too large for the dialysate due to which it does not get diffuse through it.  

• The main objective of dialysate is to withdraw toxins from the blood by the phenomenon of diffusion.  

• The membrane via which the toxins passes are small in size, therefore, only small molecules possesses the tendency to diffuse through it and due to albumin's large size it does not get diffuse through it.  

Thus, because of large size, the diffusion of albumin through the dialysate does not take place.

Answer:

c. sugar, ATP

Explanation:

C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP

basically glucose and oxygen undergo a combustion reaction among other things which will go on to produce ATP. So oxygen plus glucose or sugar produces when "burned" within a mitochondria = ATP.

If they don't agree then its a waste of time.


• Investigate only the events that affect people's lives or livelihoods since that is the

only way to make money


• Continue the procedure of an experiment or investigation under all circumstances,

even if living things are being harmed in the process

Answers

The correct answer is -Use all the data that was truly observed, not partial data that is expected or desired, skewing results.

Explanation:

In general, all practices and research should be guided by moral and ethical principles, which guarantees the research and practices are objective and participants are not harmed. In this context, an example of these principles is "Use all the data that was truly observed..." because it is ethically and morally correct to report the data that was found in the experiment or research and avoid modifying it based on financial interests, expectations, desires, etc. Also, this principle makes the research or practice objective.

(03.03 MC)What happens when a sound wave moves from air to water?
It slows down
It speeds up
It stays the same.
It reverses

Answers

Answer:

It slows down

Explanation:

Because water is denser than air the sound waves move through it faster which means that if the sound wave is coming from the water to the air then it will slow down. Also i took the test and got it right.

When a sound wave moves from air to water It slows down.

What is sound wave?

Sound is a mechanical wave that travels across a medium by means of the back and forth vibrating of its constituent particles. When a sound wave travels through air from left to right, the energy of the sound wave will cause displacement of air molecules in both the right and left directions.

The direction of the energy flow is parallel (and anti-parallel) to the particle motion. Sound waves in the air are described as longitudinal waves because of this.

Therefore,  When a sound wave moves from air to water It slows down.

Describe the structural or environmental change of your chosen macromolecule. Then predict the effect this change will have on the macromolecule. Include scientific reasoning that supports your prediction.

Answers

Answer:

Choosing protein as macromolecule.

Explanation:

The given environmental changes can lead to structural changes in protein as well:

pH - Several amino acids contain sidechains with practical gatherings that can promptly pick up or lose a proton. Changes in pH would prompt an adjustment in the charge of the amino acids, prompting charge-charge attraction or repilsion between non-interfacing amino parts.  

Temperature - High temperatures can prompt protein denaturation. Warmth can upset hydrogen bonding and hydrophobic interactions.  

Reduction or oxidation Environment - Some tertiary structure of protein folding is held by disulfide linkages. Reducing agent will lead to unfolding by introducing itself to break disulfide bonds.

Effect of these change: Sequence of amino acid and structure of protein molecule form determines function, any slight change to a protein's structure may result in the protein to become dysfunctional or produce different product.

The effect of the uneven distribution of the Sun's energy on Earth is that the equator would be warmer than the poles.

What do you mean by the uneven distribution of the sun?

The uneven distribution of the sun may be defined as the amount of sunlight that is not received equally all over the Earth's surface. This causes a fluctuation in temperature.

When there will be the Sun, the temperature of that region must be slightly higher as compared to the other region. The movement of the sun usually happens throughout the tropical regions only i.e. from the tropic of cancer to the tropic of Capricorn.

Therefore, the effect of the uneven distribution of the Sun's energy on Earth is that the equator would be warmer than the poles.
