state 4 ways by which through which a soil is depleted ​

Answers

Answer 1

Answer:

Explanation:

Leaching – Plant nutrients are lost beyond the reach of plant roots. Usually caused by excessive rainfall washing nutrients deep down into sub-soil beyond new roots reach.

Soil erosion – Top soil is lost by the agent of erosion e.g. wind, water.

Monocropping – This utilizes only specific nutrients from a particular zone making it exhausted. -It also causes accumulation of certain pests and diseases.

Continuous cropping –This continuously exhaust the fertility of land unless the the land if fallowed.

Change of soil PH -Use of either acidic or basic fertilizers affect soil pH and Consequently the presence of micro-organisms hence soil fertility affected.

Burning of vegetations –Destroys organic matter and soil structure. Nutrients are lost and soil exposed to erosion.

Accumulation of salts – Common in waterlogged areas and semi-arid areas in which poor drainage causes evaporation during the dry periods, making the soil saline.

9. If your cells were used to discover a cure for a disease do you think you should have first given consent for their use? Should you also receive something back if the research makes lots of money. Explain why.

Answers

Answer:

If my cells were used to discover a cure for a disease I don't think it would matter to give consent because I would have saved lots of people. I think I should earn just a little bit of money, because they are my cells, but I don't think I should earn a lot or most of it.

Answer:

Yes, you need to give consent because otherwise, they can not have any part of you without consent.

Explanation:

  You should expect some money even if it is a small amount to come to you due to you being the one with the cure therefor the scientist or bioglist would have to study them and would go on to trials if they make a vaccine. Always, give consent if you deem it the right choice never by force.

In what type of climate do trees produce narrower rings?

cool and dry
warm and wet
cool and wet
warm and dry

Answers

The answer is Cool and dry

Answer:

Cool and dry

Explanation: Trees tend to be sensitive to climates, so when the conditions are good the trees grows faster which results in wider growth rings and in poor conditions the tree grows slower which results in it laying down less tissue and therefore a narrower ring size. Drought and a blizzard can also cause narrower ring too. Actually, a cool way to find out if the climate conditions were good is to measure the rings of a tree every month each year. If the rings were consistently the same then you know the climate stayed pretty much the same and etc.

What is the first aid for cramps? ​

Answers

Answer:

Take a hot shower

Massage the cramped area

Yup thats all i know

We all know that any cramp in our muscles is formed due to the secretion of lactic acid . This lactic acid is formed due to our muscles doing anaerobic respiration instead of aerobic respiration . Our muscles require oxygen to break down glucose itn energy and carbon dioxide . But our body muscles wont get this much needed oxygen due to which they will start to do anaerobic respiration where they produce energy without the usage of oxygen . When such a respiration happens lactic acid is secreted in our stomach , which makes our muscles start to form cramps . So we can say that tightness or soreness of muscles due to our muscles lacking oxygen is called as muscle cramps . So , a hot bath will be a very good remedy for cramps as it will let the oxygen pass through the body , thereby completely help the lactic acid turn into energy . When lactic acid breaks down completely to form energy the muscle cramps go away . Another first aid for cramps would be massaging the area with cramps . This will also increase the oxygen flow thereby making the lactic acid change into oxygen due to which the pain will go away . Another remedy for muscle cramps would be hot nor cold pads as they help ease the pain .

Lots of hydroxides (OH) will make a solution
A.acidic B. Basic C. Neutral

Answers

Answer:

B. Basic

Explanation:

Hydroxide (OH) is an anion with the chemical formula OH-. As the formula implies, it consists of an oxygen atom and a hydrogen atom. The more electronegative oxygen atom shares electrons with the less electronegative hydrogen atom via covalent bonding.

Hydroxide ion dissolves in water to form a very strong base, hence, an aqueous solution that contains lots of hydroxides will be BASIC or ALKALINE. A solution with lots of hydroxide ions is a STRONG BASE.

Dr. Naskrecki believes that scientists will eventually identify between 50,000 and 100,000 species in


Gorongosa National Park. Why do you think he suspects there are so many more than the 2,829


species they have already identified living in the park?

Answers

Answer:

The reason why Dr Naskrecki thinks he suspects there are so many more than the 2,829 species they have already identified living in the park is because there are many species that has been identified in the world because humans haven’t gotten to most parts of the earth which makes it a lot undiscoverable.

Another one is that the species multiply rapidly and easily.

Please help! If gastric protease was put in the intestine, do you think it could still carry out its usual function of digestion? Why or why not?

Answers

Answer:

Explanation:

An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.

The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.

Enzymes are produced naturally in the body.

For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.

What are microscopic unicellular, prokaryotic organisms that move through the Earth doing both good and harm?

a. Protists
b. Eubacteria
c. Fungi
d. Archaebacteria

Answers

I think A or C. Not so sure though so if someone else answers go with their answer!

Eubacteria are microscopic unicellular, prokaryotic organisms that move through the Earth doing both good and harm. Thus, the correct option is B.

What are Prokaryotic organisms?

Prokaryotic organisms may be defined as single-celled organisms that lack a well-defined nucleus and other membrane-bound cell organelles.

Protista is a simple eukaryotic organism that is unicellular in nature. Fungi are non-photosynthetic organisms that belong to the class of eukaryotic organisms. Archaebacteria are a group of prokaryotes but they emerge from eukaryotes.

Therefore, Eubacteria are microscopic unicellular, prokaryotic organisms that move through the Earth doing both good and harm. Thus, the correct option is B.

The lytic and the lysogenic cycles are the two methods that bacteriophages reproduce.  They both begin with a bacterium that has been infected with bacteriophage DNA.

Lytic:

The phage DNA reinstructs ribosomes and the bacterium begins producing many bacteriophages.The bacterium eventually lyses and releases the bacteriophages into the environment

Lysogenic:

The phage DNA is incorporated into the bacterium's chromosome.The bacterium eventually duplicates this DNA when it undergoes fission, producing two infected daughter cells.Eventually, the phage DNA will be read by the bacterium and it will go into the lytic cycle, described above.

To sum it up, the lytic cycle ends the bacterium's life by producing offspring, yet the lysogenic cycle allows for multiple bacteria to divide and eventually undergo the lytic cycle.
