11. By what process do streams and rivers move material?
O infiltration
O mass wasting
O erosion
O weathering
Erosion is the process by which Earth's surface is worn away by the action of water, wind, ice, or gravity. Hence option C is correct.
Streams and rivers are agents of erosion, and they move material by a variety of processes, including:
Dissolution - The water in a stream can dissolve minerals from the rocks and soil that it flows over.
Suspension - Fine particles of sediment can be suspended in the water and carried downstream.
Traction - Larger particles of sediment can be rolled or bounced along the bottom of the stream.
Saltation - Small pebbles and stones can be bounced along the bottom of the stream.
The type of erosion that a stream or river causes depends on the size of the particles that it is carrying. Streams and rivers that carry a lot of fine sediment are called suspended-load streams. Streams and rivers that carry a lot of large particles are called bed-load streams.
Erosion by streams and rivers can have a significant impact on the landscape. It can create valleys, canyons, and deltas. It can also transport sediment to other areas, where it can be deposited and form new landforms.

You are studying lipoprotein processing in a strain of mutant mice. You find that these mice synthesize the same apolipoprotein composition contained in lipoproteins made in the liver and the intestines, whereas, in wild-type mice there are 2 different sized apolipoproteins in these same tissues. Examination of the mRNA processing in the mutant mice would most likely show a defect in which of the following processes?A. alternative polyadenylationB. alternative splicingC. differential cappingD. posttranscriptional modification converting a U to a T residueE. RNA editing
Answer: Option E -- RNA Editing
Explanation:
It should be noted that, RNA editing can be defined as a molecular process via which some cells can make discrete changes to specific nucleotide sequences within an mRNA molecule after it has been generated by RNA polymerase. In addition, we have two major types of RNA editing with 1 being a C-to-U change catalyzed by cytidine deaminase that deaminates a cytidine base into a uridine base, e.g C-to-U editing is with the apolipoprotein B gene in humans. ApoB-100 is expressed in the liver and apoB-48 is expressed in the intestines. The B-100 form comprises of a CAA sequence that is edited to UAA, a stop codon, in the intestines.
In humans, the quadriceps muscle is a skeletal leg muscle under voluntary control. As such, it contracts in response to signals from the motor cortex in the cerebrum. If such a muscle contracts involuntarily, that indicates:
Answer:
The correct answer is - operation of reflex arc.
Explanation:
The reflex arc is a unique and special type of neural pathway that starts with a sensory neuron and ends with a motor neuron. In this operation sensory neuron acts as the receptor and motor neuron is effector. This type of neural circuit helps in faster response.
Voluntary muscles like quadriceps muscle are normally in control voluntarily however, such muscle may contract involuntary due to reflex arc. This type of contraction takes place before the signal has even reached the brain.
In this response the sensory neuron takes the signal to the spinal cord and then motor neuron to the effector muscle for faster response.
Thus, the correct answer is - operation of reflex arc.
Which of the following is composed of a population of a species plus populations of other species? A. Community B. Biotic Potential C. Abiotic community D. Ecosystem
A Community is composed of a population of a species plus populations of other species. Thus, the correct option is A.

A recent viral video entitled "How Wolves Change Rivers" argues that the reintroduction of wolves to Yellowstone after a 70 year absence led to multiple changes in the biodiversity and ecology of the park. This is an example of a(n)
The options are missing from the question,below are the missing options;
a. Trophic cascade
b. Primary succession
c. Autograph
d. Eutrophication
e. Pioneer community
The correct answer to the question is option A.
TROPHIC CASCADE.
Trophic Cascade occurs when there is a series of significant difference/changes in the population size of organisms in the tropic level of an ecosystem.this change in trophic level occurs in a food chain and as a result of predators being in high trophic levels, they use the opportunity to indirectly promote the population of the organisms in the low trophic levels,they do so by ensuring that species that are at intermediate trophic levels are are in close watch or check.
This corresponds with the viral video of of how wolves change rivers featuring
the reintroductionn of wolves to Yellowstone after a 70 year absence which led to multiple changes in the biodiversity and ecology of the park.
Watch the video “Teen Stress.” Now, imagine that a friend confides in you that he is going to the doctor because he feels that stress might be affecting his blood pressure. He wants you to help him develop a list of questions to ask the doctor. Come up with five questions for your friend to ask about stress and blood pressure.
Answer:
questions:
Should I or can I eat salty foods?
Do I have to check my pressure immediately?
Do I have to follow a balanced diet?
Is it good to do physical activity?
Do I have to worry about the signs of eye flickering and headache?
Explanation:
Blood pressure is regulated by endogenous mechanisms, although these sometimes fail and it is necessary to take drugs to reduce high blood pressure, an example of which is beta-blockers.
Blood pressure is also regulated by diets based on low sodium consumption, necessary calories and with great contributions of nutrients since cardiac or cardiovascular health is also essential in the face of possible formation of atheroma plaques.
The increase in blood pressure with the appearance of atheroma plaques is very common, and it is also the two most frequent causes of AMI (acute myocardial infarction)
Answer:
1)How much does blood pressure rise because of stress?
2)Are there techniques that I can use to cope with stress?
3)Do these techniques help to reduce blood pressure?
4)Is exercise helpful in reducing blood pressure caused by stress?
5)Would medication help my condition?
6)Are there any other risk factors for high blood pressure?

If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have:____. a. a cyclic variation depending upon when the animal drinks. b. regular variations that range from large to small. c. slight fluctuations that are kept within a narrow range. d. a cyclic variation opposite that of the surrounding water.
Answer: Option C.
slight fluctuations that are kept within a narrow range.
Explanation:
An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).
Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.

Compare the characteristics of nitrogen fertilisers that are used for
broadcasting with a phosphate fertiliser that is insoluble in water??
Answer:
Nitrogen is mobile while phosphorus is immobile in the soil.
Explanation:
Nitrogen fertilizers are those fertilizers which provide nitrogen to the plants that is required by plants for the formation of amino acids. It increases vegetative growth of plant. Nitrogen fertilizer is highly mobile due to soluble in water and contaminated the underground water by leaching while phosphorus fertilizer are those fertilizer which provide second macro-nutrient i. e. phosphorus to the plants. Phosphorus is a vital component of energy molecule such as ATP. It is insoluble in water so it is immobile. Only 20 % of the applied phosphorus fertilizer is available to plants.

John and Joshua used a light microscope to observe a plant cell. They indicated the magnification as x1000. Given the eye piece lens magnification x10. Work out the objective lens magnification.
Answer:
Objective Lens Magnification = ×100
Explanation:
In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.
In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.
Total Magnification = (eyepiece lens magnification) × (objective lens magnification)
1000 = 10 × obejcetive lens magnification
Dividing both sides by 10
Objective lens magnification = 1000 ÷ 10 = 10
∴ Objective lens magnification = ×100

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in the laboratory. Which statement best provides evidence that the substance is a mutagen? -The cells die within hours of being exposed to the chemical. -The cells grow more quickly than those that were not exposed to the chemical. -The cells change after being exposed to the chemical, and this change is passed to the next generation of cells. -The cells continue to divide at the same rate as before they were exposed to the chemical.
Answer:
The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
Explanation:
Mutation is a process that occurs from time to time to the genetic material of living cells. Mutation is a change in the nucleotide sequence of a DNA or gene. It is usually caused by errors during replication or induced by an external substance called MUTAGEN.
A mutagen is any substance that causes mutation in an organism. Hence, according to the question, the chemical substance which is thought to be a mutagen will change the cells after being exposed to the chemical, and this change is passed to the next generation of cells.
N.B: Since mutation affects the gene, it is passed on to the offsprings during reproduction.

2 Describe why it would be an advantage for the seeds to be able to grow at any angle
Answer:
Seed grow at any angle is good for the plant because the barrier did not stop the plant growth.
Explanation:
If we planted a seed in the soil and there is any barrier such as stone or brick etc inside the soil so the roots change its direction because the seed grows at any angle. The shoot that emerge from the seed grow in upward direction if the stem is strong but some plants also grow horizontally due to weak stem so it is not compulsory for the plant to grow in only one direction, it grows whatever they want.
Climate change is a threat to polar bears and other species that thrive on sea ice. Melting sea ice and changing precipitation patterns impact the bears’ ability to hunt and survive. In the past few decades, the number of polar bears in the Arctic region has dropped considerably. How might humans help to save these species?
Answer:
c.
Explanation:
Breed Polar bears in captivity , and then release them in the colder areas.
The colder the area the less of a chance there would be for the ice to melt fast enough sweeping away the bears shelter.
Climate change is the long-term alteration in weather patterns. It impacts the polar bears of the arctic region that can be saved by breeding them in captivity and then releasing them into their natural habitat.
What is the impact of climate change?Climate change is the pattern of the disturbance in the weather and the temperature condition of the earth and its various places. It is a result of increased global warming caused by pollution.
Climate change affects the oceans and sea by raising their temperature leading to the melting of the ice caps and glaciers. This results in habitat destruction and decreases the population of arctic animals like polar bears.
To increase the population of polar bears, humans can breed them in an artificial environment and then can release them into their natural habitat like the colder places.
Therefore, the population can be increased by breeding.

The notion that the traits that help a species survive and reproduce are passed along more frequently than those that do not (i.e. differential reproduction and adaptation) is known as
Answer:
Natural selection
Explanation:
According to Darwin's theory, natural selection is the process by which individuals better adapted to their environments have more chances to survive and reproduce, and thereby their descendants will be better represented in the next generation. This mechanism exploits the existence of natural variation among members in the population which is used to select those individuals that are better adapted (i.e., with a higher adaptive fitness) for their environments. Natural selection is a key mechanism of evolution by which species change across time.
