A population bottleneck is an event corresponding to the fact that a substantial proportion of the population of a species disappears or is prevented from reproducing. There is a significantly different type of demographic bottleneck called the founder effect, which occurs when a subset of a population is, at least as far as reproduction is concerned, isolated from the main group (it does not disappear The two groups will be independent of each other).

In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals belonging to a larger population.

Which statements accurately describe the Doppler effect? Check all that apply
Mariulka [41]

Answer:

Option (1), (2) and (3).

Explanation:

Doppler effect may be defined as the change in wavelength due to the the movement of sound or radiowaves travels from the object. The frequency remains same if the distance between the receiver and sender's electromagnetic wave distance is same.

Doppler effect helps to learn about the universe behavior. Hubble used the Doppler effect to study the velocity of galaxy. The galaxy motion can be indicated by the wavelength and light.

Thus, the correct answer is option (1), (2) and (3).

Answer:

It would collapse

Explanation:

Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plant

In addition, invertebrates and other consumers that rely on these natural plant species for food are harmed by the spread of this invasive "weed". Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plan

Which characteristic of bacteria makes them efficient transgenic organisms to produce insulin or other medicines?
emmainna [20.7K]

The characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.

<h3>What do you mean by Transgenic organisms?</h3>

Transgenic organisms may be defined as an organism whose genome has been modified by the insertion of one or more foreign (non-self) DNA sequences from another species via artificial means.

A Plasmid is a circular DNA that assists in the insertion of foreign DNA sequences into the bacterial cell.

Therefore, the characteristic of bacteria that makes them efficient transgenic organisms to produce insulin or other medicines is they readily accept new genetic material.
