This is because the biosphere is the category of life. This means that plants, animals, humans, and bacteria are all apart of the biosphere.

Wind and Erosion lead to Washing away of top soil.

Erosion is the process that lead to the washing away of top soil leading to loss of nutrient, holes and many more.

The agents of erosion include wind, water and so on.

Strong wind will lead to the top soil to be remove when it is blowing. Water also when is is flowing turbulently maybe when rain fall can lead to loss of top soil.

Therefore, Wind and Erosion lead to Washing away of top soil.

Explanation:

Explanation:

mole = mass/molar mass

molar mass of KHCO3 = K + H + C + O3

39 + 1 + 12 + 3(16)

= 100g/mol

mass = 75.56

mole = 75.56/100

= 0.7556mol

Answer:

a. directly changed by the experimenter.

Explanation:

In the case of mathematical modeling, analytical modeling , and experimental sciences, the number of dependent variables based upon the amount of independent variables.

The dependent variables represent the result or outcome whose changes is being determined.

An independent variable expressed in the name form like experimental or expected variable, is a variable i.e. created in an experiment in order to verify the effect on a dependent variable

Therefore the option a is correct

Answer:

500kg.

Explanation:

Newton's Second Law relates force, mass and acceleration to one another through the equation:

F = ma

We can rearrange this equation algebraically to solve for mass:

m = F/a

Substituting our known values for the variables, we get:

m = 1500N/3m/s2

So mass of the object is 500kg.

We know it's kg because Newtons (N) are a unit defined as 1 kg/m/s2, so m/s2 cancels out when we divide :)

Answer:

A high difference in electronegativity will be present in ionic compounds since the electrons are transffered from the element less electronegative to the element more electronegative.

A small difference in electronegativity is present in molecular compounds (covalent bonds). None of the elements is strong enough to attract the electrons so the electrons are shared.

Answer:

[Zn(C₂H₃O₂)₂] = 1.85M (3 sig-figs accurate to 0.01 Molar)

Explanation:

Concentration is defined as amount of solute in a specified volume of solution. That is, Concentration = mass of solute/volume of solution (solution = solute + solvent). When concentration is in terms of Molar values the essential relationship is Molarity(M) = moles solute / volume of solution in liters.

For this problem => first, convert mass of Zn(C₂H₃O₂)₂ into moles and then the volume of solution into liters. Take ratio of moles/volume of solution (L).

=> Molar Concentration = moles of Zn(C₂H₃O₂)₂ / Liters of solution

moles of Zn(C₂H₃O₂)₂ = 85.0 grams Zn(C₂H₃O₂)₂ / formula weight of Zn(C₂H₃O₂)₂  =  85.0g/183.5g·mole⁻¹ = 0.463 mole Zn(C₂H₃O₂)₂.

Volume of solution in Liters = 250ml / 1000ml/L = 0.250 liters

Molarity of  Zn(C₂H₃O₂)₂ solution = 0.463 mole Zn(C₂H₃O₂)₂  /0.250 liters of solution = 1.85 Molar in Zn(C₂H₃O₂)₂

_____________

Note: The symbiology convention for 'molar solution concentration' is to place brackets around the molecular formula. That is, [Zn(C₂H₃O₂)₂] = 1.85M

Answer:

Overpopulated prey.

Explanation:

Because if you remove the predators from the picture who's gonna eat the prey? So it would only make sense that the prey would overpopulate! Hope this helped! (^-^)

A removal of the predator populations from an ecosystem would most likely result in overpopulated prey.

An ecosystem, sometimes known as just an ecological system, primarily made up of all the species that dwell in the physical environment. These abiotic components are linked via nutrition cycles as well as energy fluxes.

Animals contribute significantly to the transport of nutrients as well as energy through the system by consuming plants and each other. They also influence the biomass concentrations of microbial and plant populations. A removal of the predator populations from an ecosystem would most likely result in overpopulated prey.

Therefore, a removal of the predator populations from an ecosystem would most likely result in overpopulated prey.

Answer:

2 M

Explanation:

NaOH + HCl --> NaCl + H2O,

5.54 mL = .00545 L,

If we consider 2.18 M, M [molarity] = mol/L, so we have 2.18 mol/L. From this we can get the moles of NaOH.

.00545 L *  2.18 mol/L ≈ .0121 mol

The concentration of HCl can be found from the following:

.0121 mol = .00619(x) [where x = concentration of HCl]

x = 1.955 M ≈ 2 M

We equate the two as we require the same amount in order to neutralize the base.

Given values are:

As we know the relation,

→ [tex]Fs = K\times x[/tex]

or,

→   [tex]x = \frac{Fs}{k}[/tex]

By putting the values, we get

        [tex]= \frac{8.7}{190}[/tex]

        [tex]= 4.6\times 10^{-2} \ m[/tex]
