How did the amount of rainfall help determine the formation of the prairie?

Answers

Answer 1
when a moderate rainfall area had wetter years, many trees began growing. when there were drier years, fires of ten occurred and killed off the small trees. However, the fires did not kill most grasses. Therefore, prairies with grassland won out in the open areas. Where the areas were most moist and protected, forests grew.

rainfall averaged between 25 cm per year and 100 cam per year in the prairie regions. the eastern parts of the prairie usually received more rainfall that the western parts of the prairie. the difference in rainfall is onereason why the food chain varied somewhat from east to west in the prairie ecosystem.

What change in a population would you expect to see if a selection pressure was against the trait of a dominant allele in that population?.

Answers

Answer:

The change in population in the given condition would be an increase of true recessive traits in the population and there would be only a few individuals with dominant traits.

In case of selection pressure was against the dominant trait, then individuals of the population who have true recessive alleles would have an advantage over the heterozygous and dominant individuals of the population.

There would be very few individuals carrying its dominant genotype and it may eventually be extinct, however, it would be still dominant. The recessive trait would just become more prominent rather than becoming dominant.

Thus, the number of recessive traits would increase in population, and the number of dominant decrease to numbers.

A 1. 80-kg block slides on a rough, level surface. When it is traveling at 2. 00 m/s, the block hits a linear, ideal spring and compresses it by a distance of 11 cm before (momentarily) coming to rest. The coefficient of kinetic friction between the block and the surface is 0. 56. What is the force constant of the spring?.

Answers

Use the work-energy theorem.

The total work W performed on the block is done by friction and the restoring force in the spring, both of which oppose the block's motion. By Newton's second law,

• the net horizontal force on the block is

∑ F (hor) = -f - s = ma

where f = magnitude of friction, s = mag. of restoring force, m = 1.80 kg, and a is the acceleration of the block; and

• the net vertical force on the block is

∑ F (ver) = n - mg = 0

where n = mag. of normal force.

It follows that

n = mg   ⇒   f = 0.56n = 0.56mg

and so the work done by friction as the spring is compressed by 11 cm = 0.110 m is

W (friction) = -0.56mg (0.110 m) = -1.09 J

The work done by the spring as it compresses is

W (restoring) = -1/2 k (0.110 m)²

where k is the spring constant.

Then the total work is

W = -1.09 J - 1/2 k (0.110 m)²

By the work-energy theorem, this work is equal to the change in the block's kinetic energy,

W = ∆K

Since it comes to a stop, we have

∆K = 0 - 1/2 mv² = -1/2 (1.80 kg) (2.00 m/s)² = -3.60 J

So, we have

-1.09 J - 1/2 k (0.110 m)² = -3.60 J

and solving for k gives

k = (-3.60 J + 1.09 J) / (-1/2 (0.110 m)²)

k ≈ 415 N/m

Maximize the objective function p = 5x + 3y for the given constraints. X ≥ 0 y ≥ 0 3x + 6y ≤ 48 2x + 8y ≤ 56.

Answers

The maximized value of the objective function is 38

The objective function is given as:

Max P = 5x + 3y

The constraints are given as:

3x + 6y ≤ 48 2x + 8y ≤ 56x ≥ 0 y ≥ 0

To do this, we make use of the graphical method.

See attachment for the graph of the constraints.

From the graph, we have the following feasible point

[tex](x,y) = (4,6)[/tex]

Substitute 4 for x and 6 for y in the objective function.

[tex]Max\ P = 5x + 3y[/tex]

So, we have:

[tex]P = 5 \times 4 + 3 \times 6[/tex]

[tex]P = 20 + 18[/tex]

[tex]P = 38[/tex]

Hence, the maximized value of the objective function is 38

https://brainly.com/question/16826001

Answer:

Explanation:

If an objective function has a maximum value, it will occur at one of the vertices of the feasible region (i.e., the solution region for the system of inequalities). The feasible region's vertices occur at (0, 0), (0, 7), (4, 6), and (16, 0).

Use the x- and y-value from each vertex to evaluate the objective function P = 5x + 3y.

(x, y) 5x + 3y P

(0, 0) 5(0) + 3(0) 0

(0, 7) 5(0) + 3(7) 21

(4, 6) 5(4) + 3(6) 38

(16, 0) 5(16) + 3(0) 80

Therefore, the maximum of the objective function is 80.

What is Flashlight?

A portable hand-held electric lighting is known as a flashlight (US, CA), torch (UK), or torch (AU).

The light source used to commonly be a tiny incandescent light bulb, but since the mid-2000s, light-emitting diodes (LEDs) have taken their place. The common components of a flashlight are a light source mounted in a reflector, a clear cover (often paired with a lens) to shield the light source and reflector, a battery, and a switch, all of which are housed in a case.

Around 1899, the development of dry cells and tiny incandescent electric lamps made the first battery-operated flashlights feasible. Today's flashlights run on disposable or rechargeable batteries and typically use light-emitting diodes.

How many grams of lead product would theoretically be produced between 17. 0 g potassium iodide, ki, and 25. 0 g of lead (ii) nitrate, pb(no3)2?.

Answers

The number of grams of lead product that would theoretically be produced from the given reaction is; Mass of lead product = 23.6 g

Potassium iodide reacting with Lead(II) Nitrate would yield the balanced equation;

2KI + Pb(NO₃)₂ = 2KNO₃ + PbI₂

2moles : 1 mole = 2 moles : 1 mole

From online tables;

Molar mass of KI = 166 g/mol

Molar mass of Pb(NO₃)₂ = 331.2 g/mol

We are given;

Mass of KI = 17 g

Mass of Pb(NO₃)₂ = 25 g

Thus;

Number of moles of PbI₂ yielded in order to find the limiting reactant will be;

no of moles of PbI₂ from KI = (17g/166 g/mol) × (1 mole of PbI₂/2 mol of KI)

no of moles of PbI₂ from KI = 0.0512 mols

Similarly;

no of moles of PbI₂ from Pb(NO₃)₂ = (25g/331.2 g/mol) × (1 mole of PbI₂/1 mol of Pb(NO₃)₂)

no of moles of PbI₂ from Pb(NO₃)₂ = 0.0755 moles

We can see that KI produced the least amount of moles. Thus;

Mass = 0.0512 * molar mass of  PbI₂

From tables, molar mass of  PbI₂ = 461 g/mol

Thus;

Mass of lead product = 461 * 0.0512

Mass of lead product = 23.6 g
