Factors include: climate, prey availability, lack of predators, the ability to adapt to different conditions, how fast they can reproduce and grow, and how tolerant they are to a host of environmental conditions.

Hope this helps!

Answer:

An invasive species thrives in its new ecosystem and out-competes native species. So, some factors are dominance, environment, predators, and resource availability.

For each population description, identify which Hardy-Weinberg assumption is violated?
zavuch27 [327]

Answer:

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.

Explanation:

1. A small and isolated population of seals living in a stable environment with no genetic mutations.❌

1. false

Hardy-Weinberg assumption is not violated for a small population as seen in this case.

2. A large population of fish where females mate with males based on size.❌

false

Hardy-Weinberg assumption is not violated for an instance where mating is not random as seen in this scenario.

3. A population of birds with no genetic mutations that often mate with members of neighboring bird populations.❌

False

Hardy-Weinberg assumption is not violated for where gene flow is seen among population in this scenario.

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.✔

True

Hardy-Weinberg assumption is violated for in this situation due to large population size.

5. A small population of spiders living in an environment that strongly favors larger individuals.❌

false

Hardy-Weinberg assumption is violated for a small population and natural selection occurring as its obvious in this case.

There are five primary Hardy-Weinberg assumptions:

A. no mutation,

B. random mating,

C. No gene flow,

D. infinite population size,

E. No selection.

If the assumptions are exempted in a gene, the population of that gene might undergo evolution causing a resultant change in the gene's allele frequencies.

Quentin has blue eyes, blond hair, freckles, dimples and flat feet. which of these traits are polygenic?
inessss [21]
The answer is the first choice: Blue Eyes.

Polygenic traits are those controlled by two or more genes (hence the name "poly" in the term). Other examples would be skin color and height.

Hope this helps! :)

Peter was surprised to learn that, in addition to blood, there's another type of circulating body fluid that flows within separa
Kobotan [32]
The answer is tissue fluid. Tissue fluid holds far smaller quantity of protein molecules because they are too large to escape easily over the tiny holes in the capillary endothelium. Tissue fluid doesn't contain red blood cells because they are too large, but does comprise some white blood cells.

Surface currents in the Northern Hemisphere rotate in a _______ direction. In the Southern Hemisphere, the surface currents rota
trapecia [35]

Explanation:

Surface currents in the Northern Hemisphere rotate in a Clockwise direction whereas in  the Southern Hemisphere, the surface currents rotate in a anticlockwise direction. This happens because of the Coriolis effect, because of this Coriolis effect surface currents are shifted to angle of 45°. Therefore, it deflects the current towards right in northern hemisphere and towards left in southern hemisphere.
