Answer:

a. Alternate

Explanation:

Translocation is the process whereby two non-homologous chromosomes undergo mutation by exchanging their parts. This establishes new linkages in the chromosomes. Translocations occur during anaphase I of meiosis. There are two common types of segregations that occur during translocations; Adjacent-1 and Alternate segregations which both have equal chances of occurrence. A less common third one is Adjacent-2 segregation.

Adjacent-1 and Adjacent-2 segregation produces genetically incomplete gametes, therefore, the gametes are non-viable or sterile.

Alternate segregation on the other hand result in the formation of genetically complete gametes, therefore, the gametes produced are viable.

Only <em>alternate</em> segregation produces viable gametes and progeny, which also occurs in about half of meiosis and accounts for semi-sterility of translocation heterozygotes.

Resale price maintenance occurs when: a. the manufacturer suggested retail price. b. minimum prices are enforced. c. consignment
Gemiola [76]

Answer:

b. minimum prices are enforced

Explanation:

The manufacturer of certain products deals with their distributors by exploiting the market failures to negotiate ceiling and minimum prices with the threat of not purchase if the agreement is not validated.

This is done to prevent competition between reseller for the price. This makes the reseller profitable and therefore, the manufactured as well.

a bacteria population starts with 200 bacteriaa and grows at a rate of r(t) = (450.268)e 1.12567t bacteria per hour. How many ba
Virty [35]

Answer:

11,513

Explanation:

Data provided in the question:

Initial bacteria = 200

Growth rate r(t) = (450.268)e^{1.12567t}

Now,

Total growth after 3 hours = \int\limits^3_0 {(450.268)e^{1.12567t}} \, dt

or

Total growth after 3 hours = 450.268\int\limits^3_0 {e^{1.12567t}} \, dt

or

Total growth after 3 hours =450.268[\frac{e^{1.12567t}}{1.12567}]^3_0

[ ∵ \int{d(e^x)}{dt}=\frac{e^x}{\frac{dx}{dt}}]

Thus,

Total growth after 3 hours = 400 × [{e^{1.12567t}]^3_0

or

Total growth after 3 hours = 400 × [{e^{1.12567(3)}-e^{1.12567(0)}]

or

Total growth after 3 hours ≈ 11313

Hence,

Total bacteria after 3 hours = Initial bacteria + Total growth after 3 hours

= 200 + 11313

= 11,513

A customer has requested that Byrd Corporation fill a special order for 9,000 units of product S51 for $20.50 a unit. Product S5
e-lub [12.9K]

Answer:

Effect on income= $4,500 increase

Explanation:

Giving the following information:

Special offer: 9,000 units of product S51 for $20.50 a unit.

Direct materials $ 3.10

Direct labor 1.50

Variable overhead 6.40

The customer would like modifications made to product S51 that would increase the variable costs by $5.00 per unit and that would require an investment of $36,000 in special molds that would have no salvage value.

<u>Because it is a special offer, we will not have into account the fixed costs.</u>

Unitary variable cost= 3.1 + 1.5 + 6.4 + 5= $16

Investment= 36,000

Effect on income= 9,000* (20.5 - 16) - 36,000

Effect on income= 40,500 - 36,000

Effect on income= $4,500 increase

Sheridan Company reports the following information (in millions) during a recent year: net sales, $17,371.2; net earnings, $481.
jeka57 [31]

Answer and Explanation:

The computation is shown below:

As we know that

1. Return on assets is

= Net income ÷ avg total assets

where,

Avg total assets is

= (opening total assets + closing total assets) ÷ 2

= ($6,806.4 + $6,899.2) ÷ 2

= $6,852.8

Now return on asset is

= $481.6 ÷ $6,852.8

= 7.0%

2.  Assets turnover ratio = net sales ÷ avg total assets

= $17,371.2 ÷ $6,852.8

= 2.5 times

3.  Profit margin = net income ÷net sales

= $481.6 ÷ $17,371.2

= 2.8%

In the base year in a small island macroeconomy, nominal GDP was $400m. In a later year when the general level of all prices was
Cerrena [4.2K]

Answer:

Both options C and D are correct.

Explanation:

Inflation refers to an increase in the general price level of goods and services overtime. Since it is conveyed in the question that the general price level in a later year became twice as high, inflation definitely occurred. Hence, option D is correct.

Nominal GDP is the value of the total output at current market prices. Real GDP adjusts that value for inflation. As prices double, nominal GDP ought to increase from $400m to $800m. However, it actually rose to $1000m. This additional increase of $200m shows that the real GDP has risen. However, the increase in real GDP is less than 100%. This implies option C is also correct.
