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 1

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.

How does this equation represent the law of conservation of energy—that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.

Answers

Answer:

Energy from the sun goes into making the sugar molecule. This energy is released to make ATP and heat.

Explanation:

6Co2+6H20->C6H12O6(glucose)+6O2(oxygen)

The sugar molecule is created by solar energy. This energy is discharged to produce heat and ATP.

What is the law of conservation of energy?

According to the rule of conservation of energy, energy can only be transformed from one form of energy to another and cannot be generated or destroyed.

This indicates that unless energy is introduced from the outside, a system always has the same quantity of energy. In the situation of non-conservative forces, when energy is changed from mechanical energy to thermal energy yet the overall energy does not change, this is especially perplexing. Energy must be changed from one form to another in order to be used.

In photosynthesis,

6CO + 6H₂O → C₆H₁₂O₆ + 6O₂

Sunlight is used for the light energy required to produce the sugar molecule.

Therefore, the law of conservation of energy is applicable in photosynthesis as energy from the sun is utilized by all living organisms.

Answer:

because the truck is moving

Explanation:

the force of the engine is bigger than the fractional force so the truck keep moving and do not stop.

Answer with Explanation:

The forces are unbalanced because the engine force (bigger force) and the friction force (smaller force) are not equal. Their difference in force is 40 N. This makes the truck move forward or in the direction of the bigger force. Its movement is being slowed down by the friction force.

Both of the forces are acting in opposite directions, but they are not equal in magnitude. Such occurrence can make an object either slow down or speed up. It could also change its direction. This is in accordance to "Newton's First Law of Motion."

Make a prediction of this: A group of scientists recently proposed the idea that beets should replace salt for melting winter ice. The scientists pointed out that because beets grow underground, they continue to grow in freezing conditions. Thus, they hypothesized, an extract of beet roots could melt ice on roads in winter. To test this hypothesis, the scientists froze equal volumes of water on two separate plates. They spread an extract of beet roots on one plate of ice and sprinkled an equal amount of salt over the other plate. After keeping both plates at 0°C (the temperature at which water freezes) for a period of time, they measured the amount of melted water on each plate. Their results showed that the plate treated with beet extract contained more liquid water than the plate treated with salt.

Answers

Answer:

extract of beet roots could be used as antifreeze for water systems

Explanation:

In science, a prediction can be defined as a plausible conjecture that is subsequently proved (or rejected) using the scientific method. In other words, a prediction is the expected result obtained if the hypothesis is true. Scientists make predictions based on falsifiable hypotheses which can be tested through experimental and/or observational procedures. In this case, it could be predicted that the extract of beet roots could be used as anti-freeze for water systems in cold climates.

Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.

Answers

Answer/Explanation:

It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

Adaptations that help an organism survive appear quickly. True or False? And why

Answers

false

Explanation:

is not worth it to do that

According to the theory of natural selection, features that may be passed down help animals adapt to their surroundings more successfully than their kin.

What condition that make organism adaptive?

Adaptations are passable traits that improve an organism's capacity to endure and procreate in a given environment. An organism can manage in harsh settings, locate food and water, and protect itself by adapting.

This is the outcome of a process called natural selection. A species' nature gradually changes as a result of natural selection in order for it to fit into the niche.

If a species becomes extraordinarily well adapted to its habitat and the environment does not change, it can survive for a very long time before going extinct.

1. Explain how forces of attraction and repulsion exist within an atom.

Answers

Answer:

Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.

Explanation:

Answer:

1. Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.

2. Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.

3. Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.

4.

Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist: One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged. A positively charged cloud comes near a negatively charged cloud. A cloud with either a positive charge or a negative charge comes near the earth.

Explanation:

Water is a highly polar molecule. Its polarity allows it to form strong intermolecular hydrogen bonds which accounts for the forces of cohesion in the water.

The hydrogen bonds form and break with evolution of heat hence accounting for the role of water in temperature regulation.

Ice is less dense than water due to spaces in the solid. Water is regarded as a universal solvent for polar solutes. Blood and other aqueous body clouds usually contains many dissolved solutes.
