wlad13 [49]
Every organism in an ecosystem relies on other species for survival: Species diversity. An ecosystem is a b<span>iological community of interacting organisms and their physical environment. The survival of one species therefore depends on the survival of other species.</span><span>

Reduced options for mates can lead to inbreeding: Genetic diversity. Inbreeding occurs when closely related individuals breed, and this can lead to the expression of undesirable traits such as those associated with recessive genes.

Decreased diversity can lead to increased susceptibility to disease: Genetic diversity. This is related to inbreeding. The expression of recessive genes can decrease the overall fitness of a species and increase its susceptibility to disease. 

The loss of a producer could result in the loss of consumers: Species diversity. This is related to the concept of an ecosystem. Consumers rely on producers as a food source. 

When a population becomes small, diversity is lost: Genetic diversity. This is commonly known as the 'founder effect'.</span>

An entrepreneur estimates his total profit (total revenue minus total cost) for his proposed company as p(x) = x3 − 4x2 + 5x − 2
defon

break even means that the total income is equal to the total cost.

Therefore, we can equal the total gain to zero.

We have then:


p (x) = x ^ 3 - 4x^2 + 5x - 20

Equaling zero we have:

x ^ 3 - 4x^2 + 5x - 20 = 0

Rewriting the polynomial we have:


(x-4) (x ^ 2 + 5) = 0

We observe that the polynomial only has a real solution.

Therefore we have:

x-4 = 0x = 4

Answer:

the year (x) the entrepreneur will break even is:

D. year 4

What effect would overfishing most likely have on a population of fish in a lake? A. cause a gene flow to occur in the populatio
Lina20 [59]

Overfishing would result in an bottleneck effect as large number of fish is removed from a population of fishes. The size of the population has an larger effect on the amount of genetic diversity. Larger the population greater the genetic diversity.Due to overfishing, population would become smaller resulting in reducing genetic diversity. So the answer is B.

A gel electrophoresis migration pattern displaying polymerase chain reaction (PCR) products shows four strong bands. The lengths
dangina [55]

Answer:

D) The encoded protein contains four repeats of a specific sequence.

Explanation:

The polymerase chain reaction is a technique used to replicate or amplify the amount of DNA sample.

The technique employs running the DNA samples on the gel through which the DNA samples run based on their sizes.

The large-sized DNA fragment runs to a less distance whereas the small-sized DNA run to a large distance.

In the given question, four sizes of DNA bands are formed in the ratio of  1:2:3:4 which shows that the proteins encoded by this DNA have four repeats of a specific sequence of the template strand. This was confirmed when the largest band sample was again used as a sample of PCR and the PCR resulted in the four bands in similar  1:2:3:4.  

Thus, Option-D is the correct answer.
