Answer:
B.) It allows the giraffe to get food from tall trees that other animals cannot reach.
Explanation:
-
One of the distinguishing characteristics of a giraffe is its long neck. The neck has several important roles and specific functions Feeding. With the aid of its long neck a giraffe is able to reach leaves fruit and flowers high up in Vachellia or Senegalia. Formerly Acacia and other sought after tree species.

Opossums and foxes do not eat each other, so the number of births and deaths in the fox population will stay the same. decrease. The larger opossum population will leave fewer energy storage molecules for all other populations in the ecosystem, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population. decrease. Fewer energy storage molecules will be available to the fox population from the smaller rat population, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.Answer:
Decrease. Fewer energy storage molecules will be available to the fox population from the smaller rat population, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.
Explanation:
In the trophic web occurs a process of energy transference through different organisms that places at different levels. Each level feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
If any of the links change their population size (increasing it or decreasing it), it affects the superior links and the immediately anterior link.
Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.
In the exposed example, foxes are affected by the increase in the opossum population size, that a direct competitor.
Both species, opossums and foxes, feed on the rats. As long as their population sizes remain stable, no species will be hardly affected by the other. However, when a change occurs, the size of any of the populations is altered, indefectibly affecting the other populations. In this example, the opossum population increased. The more opossums are in the region, the more they will prey on rats. Opossums will become stronger competitors to foxes, whose population remains the same. Rats´ population is also affected because they do not have enough time to reproduce at a higher rate recover. So we have
opossum reproducing at a higher rateopossum population increasingopossums strongly competing with foxesmore opossums feeding on more ratsrats not being able to reproduce at a necessary raterats decreasing in numberfoxes not having enough food (rats) to feed onfoxes survival and reproductive rates affectedfoxes death rate increasingfoxes population decreasing.As more opossums are feeding on more rats, and fewer rats are available for foxes, the fox population is affected. They do not have enough food to feed on and to survive. And they do not have enough energy to reproduce. So the survival and reproductive rates in the foxes population decrease. And as they do not have enough food, their death rate increases. Eventually, the fox population decreases in size.

A sexually mature seahorse can produce thousands of offspring. What is the BEST reason overproduction of offspring by marine organisms is considered to be a reproductive advantage?
It increases competition.
It decreases competition.
It contributes to the organism’s biological success.
It causes stress on the environment which will apply stress to the creature to adapt.
Answers
Answer: D
Explanation:
There are large number of predators present in marine environment. Overproduction of offspring contributes the biological success of the organism.
What is overproduction?Overproduction is referred to the production of large number of species which can be physically supported by ecosystem.
Overproduction support survival of the fittest, by improving the genetic line.
Since the predators are more so, only that organism will survive who can adapt according to the that. This can contributes in organism's biological success.
Thus, the correct answer is C.

A. All of the tomcod in each of the rivers have this allele.
B. The percentage of tomcod with this allele remains the same from year to year in each river.
C. The rivers with high PCB levels have larger percentages of tomcod with this allele than the rivers without PCBs.

What is Tomcod populations?A benthopelagic piscivore, the Atlantic Tomcod is also known as frostfish or tommy cod. Although large ones are allegedly caught less frequently than they once were in estuary rivers, it is still abundant around the seacoast.
Although anadromous, Atlantic tomcod do not migrate very far between fresh and salt water. In shallow brackish or fresh water, sand and gravelly bottoms are where eggs are laid. Masses of eggs sink to the bottom.
Within 24 hours of hatching, newly hatched larvae swim to the surface to breathe surface air before their pneumatic duct closes. Young-of-the-year may spend their first spring and summer in fresh or barely brackish water, but they eventually move into estuaries and nearshore waters.
Therefore, Eggs from tomcod without this allele can hatch in rivers with or without PCBs, and eggs from tomcod with this allele can only hatch in rivers without PCBs.

Answers
Gel electrophoresis is a method of genetic analysis which involves seperating segments of DNA based on their size and charge.
It involves cutting DNA with various enzymes, then placing the DNA in an agarose gel. An electrical current is then run through the gel. Because DNA is a polar molecule the DNA segments will travel through the agarose cell as the current is applied. Larger fragments will travel shorter distances than shorter fragments. Two plates with 2 different DNA samples will be conducted and the orientation of the DNA strands will be used to make an analysis by comparing the 2 plates.

An ecosystem that retains structure & continues normal functions even when environmental conditions change is?
Resilient
Resistant
Reductive
Reconciled
Answers
Answer:
Resistant
Explanation:
A good aspect of the ecosystem can either be resistant or resilient when there is a disturbance or a form of deviation from the regular occurrence in the ecosystem structure, function, or both.
For an ecosystem to be resistant means it maintains structures and goes on with normal functions despite the disturbance or alteration in environmental circumstances.
Hence, in this case, an ecosystem that retains the structure and continues normal functions even when environmental conditions change is RESISTANT.
