Grassland songbirds often nest in the same grassland-wetland complexes as waterfowl, particularly in a certain part of those complexes, namely, upland habitats surrounding wetlands. Although some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds, the impact of others, especially the control of waterfowl predators, remains difficult to predict. For example, most predators of waterfowl nests prey opportunistically on songbird nests, and removing these predators could directly increase songbird nesting success. Alternatively, small mammals such as mice and ground squirrels are important in the diet of many waterfowl-nest predators and can themselves be important predators of songbird nest. Thus, removing waterfowl-nest predators could affect songbird nesting success through subsequent increases in small-mammal populations.
In 1995 and 1996, researchers trapped and removed certain waterfowl-nest predators, primarily raccoons and striped skunks, then observed subsequent survival rates for songbird nests. Surprisingly, they observed no significant effect on songbird nesting success. This may be due to several factors. Neither raccoons nor striped skunks consume ground squirrels, which are important predators of songbird nests. Thus, their removal may not have led to significant increases in populations of smaller predators. Additionally, both raccoons and striped skunks prefer wetlands and spend little time in upland habitats; removing these species may not have increased the nesting success of songbirds in the uplands enough to allow detection.
According to the passage, which of the following is true about the role played by ground squirrels in the ecology of grassland-wetland complexes?
(A) While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowl-nest predators.
(B) Whereas ground squirrels are typically important as predators of songbird nests, their opportunistic predation on waterfowl nests also has an observable effect on waterfowl nesting success.
(C) Although most waterfowl-nest predators prey on small mammals such as mice and ground squirrels, populations of ground squirrels tend to increase quickly enough to compensate for this level of predation.
(D) Although ground squirrels have been known to prey on songbird nests, a larger portion of their diets is usually provided by predation on waterfowl nests.
(E) Since larger predators tend to prefer small mammals to songbird eggs as a food source, a large population of ground squirrels plays an important role in controlling opportunistic predation on songbird nests.

Answers

Answer:

(A) While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowl-nest predators.

Explanation:

According to the passage, some predators of waterfowl nests prey opportunistically on songbird nests.  Therefore, some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds. However, some procedures such as   predator control may not always lead to benefits for the songbirds. For example, some predators of waterfowl nests such as raccoon and striped skunks are not predators of small mammals such as mice and ground squirrels who themselves are predators of songbird nests. So removing the striped skunk and raccoons from the habitat of the waterfowl and songbird nests, may not bring any benefit whatsoever to the songbirds. However, many other predators of waterfowl nests are also predators of squirrels and mice.

A solar eclipse happens when the Moon passes in front of the Sun and casts a shadow across Earth.

For a total eclipse to take place, the sun, moon and Earth must be in a direct line. The second type of solar eclipse is a partial solar eclipse. This happens when the sun, moon and Earth are not exactly lined up. The sun appears to have a dark shadow on only a small part of its surface.

Answers

Answer and Explanation:

Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.

Their wings skeleton have the shape of finger/hands like a human.

Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.

Answer:

Doves have beaks and no teeth, whereas bats have jaw bones with sharp teeth. Although they both fly, Dove and bats feature different structures that allow them to take flight. Doves have rigid, feathered wings that they flap completely in order to fly.

Answers

a. the new cell will not have instructions on how to function

Because all the genetic material is stored in the chromosomes. Thus, all information is in it.

Answer:

a. the new cell will not have instructions on how to function

Explanation:

Genetic information contained within DNA molecules regulates cell growth, replication, and cell repair. The long-chain, helical macromolecules of these deoxyribonucleic acids are formed from complex sequences of nucleotide monomers- secondary strands contain a complementary sequence joined to the leading strand by hydrogen bonding.

Chromosomes are the double-stranded DNA helixes wound around small molecules called histones. Genes or sequences of DNA encode instructions for the cell, in the form of proteins. This occurs via:  the transcription processes, translation to become proteins, defining physical traits or phenotypes.

Explanation:

Answer:

An advantage of sexual reproduction is that a genetic disorder in a parent might not affect the offspring​.

Explanation:

Since there are only two types of reproduction, sexual and asexual, andin asexual reproduction, the offspring gets all the qualities of the parent, we can determine that the offspring might not get the genetic disorder from the parent IF it is sexual. That is because there are 2 parents, hence giving a 50-50 chance to get it.

Scientific evidence shows that modern dogs, wolves, and foxes all have a common ancestor. Further evidence shows that dogs are more closely related to wolves than to fixes. Which of the following observations provides the BEST evidence that dogs are more closely related to wolves than to foxes? *
A. The diets of dogs and wolves are more similar that the diets of dogs and foxes.
B. The lifespans of dogs and wolves are more similar than the lifespans of dogs and foxes.
C. The genetic sequences (DNA) of dogs and wolves are more similar than the genetic sequences of dogs and foxes.
D. The body sizes of dogs and wolves are more similar than the body sizes of dogs and foxes.

Answers

The observation that provides the best evidence that dogs are more related to wolves than to foxes is the DNA sequence of dogs and wolves being more similar than that of dogs and foxes.

The DNA is a molecule that stores the genetic information of organisms. Thus, closely related organisms have similar information on their DNA, usually indicated by similar nucleotide sequences.

Therefore, if dogs and wolves are more closely related in ancestry than dogs and foxes, the DNA sequence of dogs and wolves will be more similar than the DNA sequence of dogs and foxes.
