plz can i get brainliest:)
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.

How much has the greenhouse gas carbon dioxide increased in the air just in the last few years? ITS DUE IN A FEW HOURS PLEASE HELP!
Answer:
approximately 2.3 parts per million (ppm) per year
Explanation:
In 2019, the global amount of atmospheric carbon dioxide (CO2) has been estimated at approximately 410 parts per million (ppm). These levels are higher than at any time in the last 800,000 years, and it has been estimated that in 2025 the CO2 levels will be higher than at any time in the last 3.3 million years. In 2018, there has been an increase of approx. 2.5 ppm, the same increase observed between 2017 and 2018. Moreover, the average increase of the CO2 levels in the atmosphere between 2009 and 2018 was 2.3 ppm each year.

Explanation:
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.
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.

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

Anna went to her physician complaining of fatigue and swelling in her legs. She explained the doctor that she exercises often and does not drink water. She also revealed that she is smoker. Doctor sad that she was dehydrated, had edema and probably hypoproteinemia (low plasma protein concentration). He ordered some blood tests and ECG. ECG revealed that she had atrial fibrillation, which he said might explain her fatigue. Doctor advised her perhaps exercise more moderately, drink water and that she should definitely stop smoking.
- How might a blood test help to diagnose the cause of Jessica’s fatigue and edema?
- How does her hypoproteinemia relate to her edema?
- How would dehydration influence blood volume, stroke volume, and cardiac output?
- What is atrial fibrillation, and how does it appear on an ECG?
- How might atrial fibrillation explain Anna’s fatigue?
what happens to a animal cell placed in a hypotonic solution
Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
Explanation:
Hypotonic solution is a solution which, contains lesser solute concentration. If animal and plant cells are kept in a hypotonic solution then endosmosis will occur. Endosmosis is a process in which the water molecules move from outside of the cell of lower solute concentration to the inside of the cell of higher solute concentration through the cell membrane or cell wall. Due to endosmosis, both animal and plant cells will swell.

Provide one example of Mutualism.
You must explain: The two organisms, how they both benefit, and any other necessary information to explain their interaction.Immersive Reader
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).
What process is occurring in this picture at B?
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.

Based on the patient's symptoms and doctor's initial prognosis, how does dehydration affect a person's blood flow and blood pressure?
The patient's blood viscosity would increase, causing blood flow to increase and blood pressure to decrease
The patient's blood viscosity would decrease, causing the blood flow and blood pressure to remain at a stable rhythm
The patient's blood viscosity would decrease, causing the blood flow to decrease and the blood pressure to also decrease
The patient's blood viscosity would increase, causing the blood flow to decrease and the blood pressure to increase
Answer:
Maintaining a normal blood volume is necessary for blood to be able to adequately reach all of the tissues of your body. When you're very dehydrated, your blood volume can decrease, leading to a drop in blood pressure. When blood pressure drops too low, your organs won't receive the oxygen and nutrients they need. might be what you are looking for but if not i will change it
