Answer:
d
Explanation:
A semipermeable membrane has a 2 percent salt solution on one side and a
15 percent salt solution on the other side. What will most likely occur?
A. Osmosis of water from a low concentration of salt to a high
concentration
B. Osmosis of water from a high concentration of salt to a low
concentration
c. Active transport of salt until all the salt is concentrated on one
side
D. Facilitated diffusion of salt until both concentrations are equal
Answer:
A
Explanation:
Water naturally travels from a low solute concentration to a high solute concentrated.
The correct answer is B. Osmosis of water from a high concentration of salt to a low concentration. This is due to the process of osmosis, which is the movement of water molecules from an area of low solute concentration to an area of high solute concentration.
What is the context of it ?In this case, the high salt concentration is on one side of the semipermeable membrane and the low salt concentration is on the other side. Therefore, water molecules will move from the side with a higher salt concentration to the side with a lower salt concentration, resulting in the osmosis of water from a high salt concentration to a low concentration.
The other options are incorrect because they do not accurately describe the process that occurs. Option A is incorrect because it states that osmosis will occur from low to high concentration, which is the opposite of what occurs in this situation.
Option C is incorrect because active transport requires energy and is used to move molecules against a concentration gradient, which is not happening here. Option D is incorrect because facilitated diffusion does not require energy and is used to move molecules down a concentration gradient, which is not happening here.

The system in the body which carries information from the glands and organs to brain is endocrine system.
What is endocrine system?
All mammals, birds, fish, and many other forms of living things have endocrine systems, commonly known as hormone systems. They are composed of:
Throughout the body, there are glands; hormones that are produced by the glands and released into the bloodstream or the fluid around cells; and receptors in various organs and tissues that detect the hormones and react to them.
All bodily components are affected by hormones, but only target cells with the right receptors can react. In both humans and other vertebrates, more than 50 hormones have been discovered.

How would the quantity of stomata compare between plants in tropical environments and plants in hot, arid climates? -Plants in tropical climates would have fewer stomata because they would need to prevent the absorption of too much water from the atmosphere. -Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves. -Plants in hot, arid climates would have more stomata because they would need to release heat from the leaves to prevent dehydration. -Plants in tropical climates would have more stomata because they would need to absorb more water from the air than plants in arid climates.
Answer:
-Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves.
Explanation:
I took the test and got this right.
The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata. So, the correct option is B.
What is Stomata?The little apertures known as stomata are found just on epidermis of leaves. Stomata are visible under a light microscope. Stomata can be found on the stems and other portions of various plants. In exchange of gases and photosynthesis, stomata are crucial.
Because they need to take in more airborne water than plants in arid areas, tropical plants would have more stomata. Since they must prevent unwelcome moisture loss from plant leaves, plants in warm, arid climates would develop fewer stomata. The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata.
Therefore, the correct option is B.

Answer:
Hey!
Your answer is CLEAR CUTTING...
Explanation:
Clear cutting is when people/ industries harvest and regenerate trees areas in which all trees are cleared from a site completely...
HOPE THIS HELPS!!
Clear cutting can cause secondary succession. So, the correct option is A.
What is Secondary succession?When a place is disturbed but not severely enough to completely clear it of all vegetation and soil, secondary succession happens. Secondary succession can be started by a variety of disturbances, including fire, flooding, high winds, and human activities (such as logging of forests).
After the primary succession has indeed been disrupted as well as some animals and plants are still there, the secondary succession occurs. For the reasons listed below, the secondary succession is typically quicker than the primary succession.
There is already earth in place.The soil may still contain seeds, roots, and subsurface vegetative organs.Therefore, the correct option is A.

Why do waves that travel through basalt have a higher velocity than a wave traveling through sand?
Answer:
Read Explanation
Explanation:
Even though the technology does not exist to travel into all of Earth’s layers, scientists can still learn a great deal about Earth’s structure through seismic waves. Seismic waves are vibrations in the earth that transmit energy and occur during seismic activity such as earthquakes, volcanic eruptions, and even man-made explosions. There are two types of seismic waves, primary waves and secondary waves. Primary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A). Secondary waves, or S waves, are slower than P waves. The motion of secondary waves is perpendicular to the direction of the wave travel, similar to the motion of vigorously shaking a rope

Which explains why the reflex reaction is important in certain situations?
O A. Motor neurons cannot form action potentials.
O B. The brain has no control over motor neurons.
O C. Interneurons are too slow at sending signals through the spinal
cord.
O D. Sensory neurons do not use neurotransmitters to send signals.
Answer:
Answer:c
Explanation:
The reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.
What is the reflex?The reflex is an automatic (read immediate and constant) bodily reaction to stimulation. According to Pieron, the reflex corresponds to any activity or variation of activity of an effector (muscle, gland, etc.)
With this information, we can conclude that the reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.

A population of rhinos was separated by a large river.
Since rhinos are lousy swimmers, they were unable to cross. Environmental conditions were very different on either side of the river, and over time these two groups of rhinos evolved such different characteristics that scientists classified them as two
different species. This is an example of:
A.sympatric speciation
B.homologous speciation.
C.analogous speciation
D.parapatric speciation
E.allopatric speciation
Answer:
B
Explanation:
Environmental conditions were very different on either side of the river, and over time these two groups of rhinos evolved such different characteristics that scientists classified them as two different species. This is an example of homologous speciation.
What is homologous speciation?
Organs or skeletal components of animals and organisms that are homologous suggest a connection to a common ancestor because of their similarity.
The appearance and purpose of these structures need not be identical. Other mammals with tails include rats, cats, and monkeys. Mammals have flexible vertebrae in their tails, which act as an extension of their torsos.
Although their primary purpose is to fend off insects, tails can also provide a sense of equilibrium for more reclusive species like cats.
