Explain 3 ways of checking soil depletion​

Answers

Answer 1
You can check soil depletion by:

1. Contour ploughing

Ploughing along contours on a slope prevents soil from being washed away by rains and or by surface run-offs. Contours act like bunds. Terraces are leveled into step-like small fields with even slopes. Doing this is common in Asian countries.

2. Terrace Farming

On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. This is practiced in Asia and the USA.

3. Strip Cropping

In this system, crops are grown by alternate strips of land in order to check the effect of the winds.

I am 100% sure that the correct Answer is:

Convection current

Please do have a great rest of your day!

The cycle that powers the ocean currents, weather, and tectonic plates it called convection current​. The correct option is d.

What is convection current?

Convection is the spontaneous flow of a single or multiphase fluid caused by the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity.

Convection currents are generated by radioactive decay in the core as heat rises and falls within the mantle. The plates are moved by convection currents.

Plates move apart where convection currents diverge near the Earth's crust. Plates move towards each other where convection currents converge.

Convection currents propel Earth's rigid tectonic plates through the planet's fluid molten mantle.

Tectonic plates move away from each other in places where convection currents rise up towards the crust's surface, a process known as seafloor spreading.

Thus, the correct option is d.

30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample.

Predict whether these concentrations would increase, decrease, or stay the same if nitrite-nitrifying bacteria were added to the sample.

Answers

If 30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample and nitrite-nitrifying bacteria are added, the concentration of the nitrate would increase, that of the nitrite would decrease, while that of ammonia would remain the same.

The process of converting ammonia to nitrate, also known as nitrification occur in two stages:

The conversion of ammonia to nitrite by ammonia oxidizing bacteria.The conversion of nitrite to nitrate by nitrite-oxidizing/nitrifying bacteria.

Now, if nitrite-nitrifying bacteria is added to the soil sample above, it means that only the nitrite would be converted to nitrate. The bacteria will not be able to oxidize ammonia.

Hence, some of the nitrite would be converted into nitrate leading to the reduction in the concentration of the former, and an increase in the concentration of the latter. The concentration of ammonia will remain unchanged.

A monohybrid cross is the hybrid of the two individuals with homozygous genotypes or heterozygous genotypes which result in the formation of opposite phenotype for a certain genetic trait. The cross between the two monohybrid traits such as flower color or plant height is called a Monohybrid Cross.

When two plants, one with homozygous yellow leaves (YY) and one with heterozygous yellow leaves (Yy) are crossed, then the offspring will have yellow leaves and none of the offspring will have red colored leaves as this is a recessive trait and it requires to be present in homozygous condition to show its effect.

Therefore, the correct option is A.

HELPP!! Describe how the enzyme transforms the substrate. Include in your answer the vocabulary terms: substrate, active site, enzyme, product(s).

Answers

A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
