In your own words, explain how energy moves through an ecosystem
Answer:
The energy in most ecosystems flows through the food chain. In physical ecosystems and most marine ecosystems, the energy flow starts in green plants that harvest some of the sun’s energy. The plants are then consumed by animals, bacteria, and other creatures, which are themselves eaten by other creatures. At each step in the food chain, energy is lost as heat.

A grassy meadow high in the Sierra Nevada Mountains of eastern California is known to support a variety of organisms. During the summers when grass is thick and lush, and wildflowers abound, butterflies take advantage of this abundant nectar source. Bears graze on the berries in shrubs at the edge of the meadow. Deer also forage at the edge of the meadow. In the early mornings, coyotes are known to prey on the squirrel and mouse populations that burrow into the meadow soil. A variety of birds prey on the butterflies and other flying insects, such as bees and wasps. The coyotes would be classified as ____. Group of answer choices
Answer:
carnivore and secondary consumers
Explanation:
Carnivorous are organisms that fulfill their energy requirements by feeding animal tissues and/or meat, either hunting or scavenging. In the food chain, secondary consumers are those organisms that obtain energy by eating primary consumers (herbivores). In this case, the coyotes can be easily classified as carnivores and secondary consumers because they hunt squirrels and mice, which in turn eat autotrophic plants (primary consumers).

Which of these is the source of the variation in wing color within the Peppered Moth population?
natural selection
pollution
genetic variation
Answer:
Genetic variation
Explanation:
It could lead to natural selection, but natural selection isn't the cause. Many years down the road you could see a particular variation having a higher population, which is the result of natural selection/survival of the fittest via better camouflaging from predators.

Use your understanding of prevention and treatment of viruses to answer the questions below.
A
is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.
I'm a bit confused about this question. But I will try my best to answer. :)
To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu. The shot contains a small portion of the flu itself. The flu remains dormant until the body decides to activate it or fight it off. This also helps the body become more immune to the virus/sickness and fight it off easier.
I hope this helps! :)
A hapten is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.
What is the Immune response?The immune response may be defined as the type of reaction that occurs in response to specific antigens or foreign agents. Such types of responses defend the organism against foreign invaders.
A hapten is essentially an incomplete antigenic particle. Such small substances or molecules only elicit an immune response when attached to a carrier known as proteins.
Carrier molecules typically do not elicit an immune response by themselves.
Therefore, it is well described above.

A high population of greater prairie chickens once inhabited the prairies of Illinois. The conversion of the prairies into agricultural land caused the chickens to lose their habitat. Studies have concluded that this change greatly reduced the greater prairie chicken population. The habitat loss also resulted in a decrease in the population’s genetic variation.
Which change in the gene pool occurred in the greater prairie chicken population?
gene mutation
gene flow
genetic drift
genetic resistance
The answer is C. genetic drift
Genetic drift affects the population size and decreases genetic variability by setting some alleles and losing others. Option C. The exposed example is a case of genetic drift - bottleneck effect -.
What is genetic drift?
Genetic drift is an evolutive force. It refers to the random change that occurs in the allelic frequency of a population through generations.
The magnitude of this change is inversely related to the size of the original population.
These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic variation in the population decrease.
Genetic drift affects a population and reduces its size dramatically due to
a disaster or pressure ⇒ bottleneck effectthe population split ⇒ founder effect.The exposed example is a case of the bottleneck effect. The conversion of the prairies into agricultural land and the consequent habitat loss is the pressure acting on this prairie chickens population. The population decreases in size and decreases its genetic variation.

Which of the following is an example of deposition?
a. glaciers wearing down layers of rock b. a muddy river carrying sediment downstream c. ponds filling up with sediment and becoming marshes d. frost wedging splitting rocks apart
Glacial erratics are the name given to these rocks. Erratics serve as a log of a glacier's journey. Complex flow patterns can be discovered by looking for the bedrock units that match with erratics. Thus option A is correct.
What glaciers wearing down layers of rock?The rocks and the ground below are both eroded as a result of the friction caused by glaciers carrying rocks. In this manner, glaciers pulverize rocks and remove dirt. Mountain valleys with steep sides are created by advancing glaciers carving out basins. Moraine, an eroded debris, is frequently seen on and surrounding glaciers.
Mechanical weathering causes the rock on valley walls to become loose as glaciers flow, where it then falls as debris. Rocks of any size, from enormous boulders to silt, can be carried by glaciers. Over many years and decades, these rocks can be transported a great distance.
Therefore, glaciers wearing down layers of rock.

An advantage of using natural gas, rather than oil, as a fuel is that natural gas is less of a contributor to global warming because it does not release CO2 when it burns less of a contributor to global warming because it does not release CO2 when it burns A less expensive because most reserves are in the United States less expensive because most reserves are in the United States B more abundant because it is a by-product of photosynthesis more abundant because it is a by-product of photosynthesis C cleaner because it burns more completely cleaner because it burns more completely D safer to store because it is a gas
Answer:
A. less expensive because most reserves are in the United States
Explanation:
Natural gas is less expensive because in the united states there are huge amount of reservoirs present. According to the research, the United States has about 475 trillion cubic feet of proved reserves and 2,392 trillion cubic feet of unproved reserves of dry natural gas. It is a clean source of energy comparatively coal and fossil fuel because it produces less amount of carbondioxide and other pollutants in the atmosphere so that's why the natural gas is less expensive and prefers in usage.
A woman bought 10 crates of eggs from the market. On getting home, she realized that 15 eggs were broken. What is the ratio of broken eggs to unbroken eggs.
Answer:
B:U = 1:20
Explanation:
Let the number of broken eggs be B.
Let the number of unbroken eggs be U.
Given the following data;
Number of crates of egg = 10 crates
But, 1 crate of egg = 30 eggs
10 crates of egg = 30 * 10 = 300 eggs
B = 15 eggs
U = 300 eggs
Ratio B to U = B:U
B:U = 15:300
Dividing by 15, we have;
B:U = 1:20

All of the following are functions of asexual reproduction except producing gametes.
What do you mean asexual reproduction?Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
Asexual reproduction is a type of reproduction in which only one parent is involved. There are basically 5 types of asexual reproduction. These are binary fission, budding, vegetative reproduction, fragmentation and by spores.
The major disadvantages of asexual reproduction are: Lack of diversity- Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent.

b
an orange house cat breeding with a feral cat in the wild
c
using wild horse DNA to create a transgenic race winning horse
d
breeding a cow with a bull who produces large muscular baby bulls
Answer:
D
Explanation:
Selective breeding is when you a breeding 2 organisms in order to make a specific trait be passed down to the offspring. Since you the offspring in this scenario have larger muscles, this is selective breding because you are "choosing" a trait. A and B don't mention specific traits, and C is wrong because you can't garuntee that the offspring will win a race. D is the most logical choice
