What happens when you finally get better from the H1N1 flu virus???????
Answer:
Most people who get the flu (either seasonal or 2009 H1N1) will have mild illness, will not need medical care or antiviral drugs, and will recover in less than two weeks. Some people, however, are more likely to get flu complications that result in being hospitalized and occasionally result in death
On day five of the flu, you should be starting to feel better. Your fever should be gone and the congestion should be lessening, though your cough may linger. You should still stay home, rest, and take plenty of fluids

Which learning process occurs when the same response happens in reaction to many similar stimuli? A. acquisition B. discrimination C. extinction D. generalization Please select the best answer from the choices provided A B C D
The learning process that occurs when the same response happens in reaction to many similar stimuli is option D: generalization.
Why is generalization important in learning?It is significant because it enhances the possibility that the learner will be successful in completing a task without the help of a specific teacher or resources that are only available in one instructional environment. The value of skill generalization is frequently undervalued.
Therefore, The idea of generalization holds that if the conditions in the settings are deemed to be similar, humans and other animals can apply knowledge from the past to learning situations in the present.

which of the following does not contribute to the formation of the mid atlantic ridge
Answer:
This submarine Mid-Atlantic Ridge owes its formation to the movement of the continental plates on either side of the ocean. As these plates slowly separate, they leave gaps in the earth's crust. This allows molten rock from beneath the earth's crust to reach the surface, forming a new part of the ocean floor

The molecules of a cell membrane are
O linked to other cells to form long chains of cells.
O floating around one another in a fluid structure.
O locked together in a rigid structure.
connected to the cytoplasm by strong chemical bonds.
Answer:
O floating around one another in a fluid structure
Explanation:
Cells are made up of varying types of molecules in order to achieve a fluid, stable plasma membrane. The membrane mainly consists of:
lipids proteins cholesterolLipid membranes help maintain selective membrane permeability. The lipids, formed from glycerol and saturated/unsaturated fatty acids, are made up of polar heads and non-polar tails; they typically only allow the movement of small non-polar molecules. Larger molecules are transported through integral proteins; other types, are peripheral, and may have specialized functions like cell signaling.
Cholesterol molecules keep the lipids in place, and ensure membrane fluidity. In extreme temperatures, they help the membrane to maintain its shape without becoming too rigid.

Read the sentence. The famous physicist who discovered the element received much acclaim and many prestigious awards. The underlined phrase is a(n) phrase.
Answer:
The underlined phrase is a verb phrase. This is the case because the head of the phrase is the transitive verb to receive which, in this case, is in the past simple form.
The transitive verb in question, as I have said, is a transitive verb which takes two arguments: the NP "the famous physicist who discovered the element" and the NP "much acclaim and many prestigous awards".
Explanation:
The underlined phrase, "who discovered the element," is a relative clause.
What are Clauses?A clause is a group of words that includes a subject, a predicate, and perhaps a verb. Clauses can be used as complete sentences or as fragments of sentences. Usually, one or more clauses are linked in different ways to form a sentence.
Independent and dependent clauses are the two primary categories of clauses. A dependent clause cannot be a sentence by itself, whereas an independent clause can be. Subordinate clauses, also known as dependent clauses, sometimes begin with a subordinating conjunction or a relative pronoun. "Who discovered the element" (underlined) is a relative clause modifying "the famous physicist".
Therefore, the underlined phrase, "who discovered the element," is a relative clause.

6. What is the benefit of a scientific name vs. a common
name
Answer:
We use scientific names because it gives us a good way to organize species and name them.
Explanation:
In contrast to common names, a scientific name is the same in all languages and gives an entity a distinctive name, making it possible for two individuals to be certain that they are speaking about the same thing.
What is a scientific name?A common and official way to name species is using binomial nomenclature. Two names that are both borrowed from Latin make up the nomenclature.
But it can also be derived from other tongues. This kind of name is sometimes referred to as a binomial name or a scientific name.
A formal way of identifying species of living things by assigning each one a name made up of two components is known as binomial nomenclature, also known as binominal nomenclature or binary nomenclature in taxonomy.
Therefore, a scientific name is the same in all languages and gives an entity a distinctive name.

Over time newer layers will be recycled by transfor boundaries and older
layers will be created from convergent boundaries
Answer:
3rd answer
Explanation:
Over time newer layers will be created from divergent boundaries and older layers recycled by convergent boundaries. The correct option is C.
What is plate tectonics?Tectonic plates, which are basically the large slabs of rock which usually divide the Earth's crust, are constantly moving and reshaping the Earth's landscape.
Plate tectonics theory proposes that the Earth's outer shell (lithosphere) is divided into several plates that glide over the rocky inner layer above the soft core.
Cooler parts of the Earth's crust were pulled downwards into the warmer upper mantle around 4 billion years ago, damaging and weakening the surrounding crust.
According to the authors, the process repeated itself until the weak areas formed plate boundaries.
Divergent boundaries will create newer layers over time, while convergent boundaries will recycle older layers.
Thus, the correct option is C.

please tell me why my dump truck is so fat anyways
A: Dump trucks are so big or fat because they are used to haul large loads of loose materials, such as dirt, rocks, sand, and coal, to construction sites, factories, or power plants. The open bed features a hinge at the rear of the truck so that hydraulic pistons located at the front of the bed can lift the front to dump the contents of the bed at the delivery site. The title of the world's largest dump truck went to the BelAZ 75710 which began moving rocks and coal in a mine in Siberia in 2014. The BelAZ 75710 is as long as two buses parked end to end, six times more powerful than modern Formula 1 racing cars, and heavier than a loaded Airbus A380 airplane. The entire vehicle costs over $6 million with each tire costing $42,000.

Would the carrying capacity of an area for a species be effected by the other species that live in the same area?
No, each species is separate.
Only if the two species share food.
Only in the winter when food and shelter are more scarce.
Yes, all the populations in a community effect each other.
Answer:
I would say yes, all the populations in a community affect each other.
Explanation:
In biology, the concept of carrying capacity pertains to the number of organisms that can survive in a certain environment based upon their resources. So, if the species relies on the other species that live within the same environment, it would obviously affect that species.
Inside the cell is 40% helium and outside the cell is 20% helium. Which of
the following will occur? *
A. helium will move out of the cell
B. helium will move into the cell
C.helium will not move
Answer:
A. Helium will move out of the cell
Inside the cell the concentration is higher than concentration off outer cell so the inner helium well more about of cell
Answer:
[tex]\boxed {\boxed {\sf A. \ Helium \ will \ move \ out \ of \ the \ cell}}[/tex]
Explanation:
Diffusion is the movement of particles from a high concentration to a low concentration. This is the process occurring in this question.
In this cell, 40% helium is inside the cell.
20% is outside of the cell.
40 is greater than 20. Therefore, the helium wants to move from the area of 40% to 20%, which is also from the inside of the cell to the outside. Basically, the helium moves out of the cell.
So, the best answer is choice A: helium will move out of the cell.
