1. What is microevolution?

2. Explain through the process of microevolution how natural selection produces adaptations while other evolutionary forces (specifically genetic drift, migration/gene flow, and non-random mating) may produce random evolutionary changes within populations.

3. Explain why evolution is a population-level phenomenon. Why does population size affect some evolutionary mechanisms, but not other(s)?

Will give a thumbs up for a good answer. Please help me!

a. Two point charges each of magnitude +5.010-9 C are placed 8.0 cm apart in air. Calculate, i. the electric potential, and ii. the electric field strength at a point, P which is 5.0 cm away from each charge. b. An electron of charge 1.610-19 C moves from a point midway between the charges and on the line joining them, to point P. i. Calculate the work done. ii. Discuss the energy changes in the process

In a closed-market economy with unionized labor, suppose unions suddenly get a significant negotiation power on labor contracts at time t∗ and thereby enforced a real wage rate that is 10 percent higher than the market-clearing real wage rate. What would be the effect of this on unemployment, rental rate of capital, real interest rate in long run and very-long run? What would be the effect of using expansionary fiscal policy against this? Explain in detail by showing the changes in the relevant markets.

Define the profit function of the private insurer in the line of health insurance. That is, what are the revenues and costs of the insurance firm? Based on your definition, analyze the effects of the following exogenous changes on the insurer's profit: a.) an increase in insurance rate; b.) an increase in the insurer's share price in the stock market; c.) a general increase in health care expenditures; d.) an increase in population size; e.) an increase in the country's unemployment rate; f.) a shift of the payment system from fee-for-service to capitation.

SL is faced with a decline in demand due to the downsizing of its major customer. LR, the company's controller, is considering a number of changes which may affect the company's profitability.

Explain how SL's break-even point would change if:
-The selling price per unit decrease.
-Fixed costs increased throughout the entire range of activity.
-Sales people were now compensated on 75% commission and 25% salary and opposed to 75% salary and 25% commission as they were prior.

1) Annie says "you can't run a linear system on a finite planet indefinitely." Another way to say this is you can't have unlimited economic growth with limited resources. What does this mean and what does it mean for the future?

2) What changes are needed to ensure that our way of life supports rather than undermines the planet's biological systems on which we depend? (Use in your response 2 of the following terms, externalizing costs, dioxins, perceived, or planned obsolescence.)

In roughly 3 pages, reflect upon the reasons WHY the sugar is in existence to begin with, explain your thoughts/feelings about this. Do you foresee any changes in the future? Explain. Take a stance, for or against sugar and/or forms of sugar in our food. 
A fairly solid reason explanation of WHY you feel this way. Make clear your personal feelings/beliefs about the use of sugar. Clarify your position by citing reasons and give examples. Include at least four references.

A space station shaped like a giant wheel has a radius of 1.00 x 102 m and a moment of inertia of 5.00 x 108 kgm2. A crew of 150 lives on the rim, and the station is rotating so that the crew experiences an apparent acceleration of 1.0g. When 120 people move to the center of the station for a union meeting, the angular speed changes. What apparent acceleration is experienced by the mangers remaining at the rim? Assume the average mass of a crew member is 65.0 kg.

A company produces and sells two products – A and B. During January 2020 A were sold at the
amount of $19,200 and its variable expenses were $6,336. B were sold at the amount of $32,800
and its variable expenses were $11,344. Fixed expenses were $32,280.
Compute
1. Break-even point for the company in total sales dollars. Show your calculation

2. If the sales mix shifts toward A without changes in total sales, what is the company’s break-
even point? Explain.
