What process is occurring in this picture at B?

Answers

Answer:

Translation

Explanation:

Translation is the second process that occurs in protein synthesis. It is the process whereby mRNA template is used to synthesize an amino acid sequence, which eventually becomes a protein.

The process of translation occurs in the cytoplasm (specifically in the ribosome). As depicted in this image, the mRNA produced during transcription is transported out of the nucleus into the cytoplasm. A RNA molecule called tRNA reads the mRNA sequence (codon by codon) and carries corresponding amino acid into the growing amino acid sequence.

Hence, according to this question, the process occuring at B according to this image is TRANSLATION.

Search using the internet on how you can expand or enhance one's knowledge of animal/fish raising.​

Answers

Answer:

Fish farming involves raising a variety of aquatic animals, such as fish, mollusks and shrimps in an enclosure such as a tank or pond. With the surge in demand for healthy animal protein the  demand for fish and fish products is on the rise. Fish farms have the potential to produce fish for home consumption at about $0.90/lb which is a considerable saving when compared to supermarket prices of over $2.00/lb.

The first step for fish farming is to determine what you are going to do with your full-grown fish. You need to know the purpose, whether you are going to keep fish as a pet or for fish meat. This will decide a lot of things like the space requirements, equipment and capital requirements. If you intend to keep fish as a pet for showcase then a small tank or a backyard small fish farm is sufficient. If you intend to put a small fish farm with one or two ponds then also with a little business mindset you can market 1000 to 2000 lb of fish.  

This will also require you to set up a business entity and have a business mindset.The costs associated with raising different types of fish varies because different fish need certain temperature water to live. The type of fish also decides the requirement of equipment and the feed cost. There are lots of laws about raising fish and animals, and even more, stringent laws related to raising animals that are going to be consumed as food.

Before starting fish farms or fish hatchery of any size or type it is advisable to check local laws and the need of permits  to do so in your area.Normally you will get a license to operate your fish farm for a year which will be renewable. You need to submit the following documents to apply for the license:

Filled in application form

Sketch or aerial map of the facility layout, including dimensions

Copy of fish health certificate

Copy of stocking permit

Letter of a written permission from the landowner (in case if you are not the landowner)

Answers

Answer:

Cattle and egret

Explanation:

Mutualism is a type of symbiotic relationship involving two organisms whose actions cause them to benefit from one another. In other words, both organisms do one another a favour, hence, the relationship is said to be MUTUAL.

- An example of a mutualistic relationship is that of CATTLE AND EGRET. Cattle gets infested by certain parasites like ticks and fleas, which feeds on their blood. Egrets are bird species that flock around cattle to feed on these insect parasites. This relationship is mutual because, egrets help the cattle get rid of their parasite problem (cattle benefits) while the cattle provides food for the egrets when they harbor these parasites on their body (egret benefits).

The above graph shows how temperature affects the rate of a reaction that uses the catalase enzyme. What trend is shown by the graph?
A.
Between zero and twenty-seven degrees Celsius, the rate of the reaction increases as the temperature increases.
B.
Between thirty-seven and sixty degrees Celsius, the rate of the reaction increases as the temperature increases.
C.
Between zero and twenty-seven degrees Celsius, the rate of the reaction decreases as the temperature increases.
D.
Between sixty and one hundred degrees Celsius, the rate of the reaction decreases as the temperature increases.

Answers

Answer:

the answer is A.

Explanation:

B and C are wrong because they are describing the opposite of what is happening in the graph. D is wrong because there is no change in the reaction rate between 60 degrees and 100 degrees.

The rate of the reaction rises with temperature between zero and twenty-seven degrees Celsius, hence option A is correct.

How does enzyme activity is affected?

At various temperatures, catalase functions in different ways. The catalase enzyme becomes more active as the temperature rises from 0°C to about 30°C Up to 100°C, and catalase activity declines as the temperature rises.

The hydrogen bonds between molecules of hydrogen peroxide relax as the temperature rises toward the optimal point, facilitating catalase's reaction with the molecules.

Temperature raising speeds up a process, and lowering temperature slows it down. If the temperature rises over the optimal range, the enzyme denatures and its structure is destroyed.

Therefore, but extremely high temperatures can denature an enzyme, causing it to lose its form and cease functioning. Every enzyme has a preferred pH range, hence option A is correct.

Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.

What is corrosion?

The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.

The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.

Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.

Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.

Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.
