? 3. Explain why Surtsey provided ideal conditions for studying primary succession:
Answer:
Due to newly formed land.
Explanation:
Surtsey provided ideal conditions for studying primary succession because due to volcanic eruption all the vegetation and living organisms are destroyed from the surface and the land has no vegetation. Primary succession only occurs when the land is colonized for the first time after the formation of land due to natural disaster such as volcanic eruption etc. So we can say that Surtsey provided the conditions for observing primary succession.
An easy way to think of independent and dependent variables is, when you're conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect. True True False
Answer:
True, True, True
Explanation:
Not exactly sure what you are asking, but I'm guessing you want confirmation.
Which best describes the relationship between temperature and dissolved oxygen in a lake?
As temperature increases, dissolved oxygen increases.
As temperature increases, dissolved oxygen decreases.
As temperature decreases, dissolved oxygen decreases.
A change in temperature has no
effect on dissolved oxygen.
Explanation:
Air and Water Temperature Increases
For example, increases in water temperatures are expected to result in the following: Lower levels of dissolved oxygen due to the inverse relationship that exists between dissolved oxygen and temperature. As the temperature of the water increases, dissolved oxygen levels decrease.
Increasing the rate of an impulse is the function of the_________.
A myelin sheath
B. axon terminals
C. cell body
D. axon
Answer:
Myelin sheath
Explanation:
Increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.
What is Impulse?The Impulse may be characterized as an electrical signal that can be transmitted along a nerve fiber in response to an external or internal stimulus.
The Myelin sheath increases the rate of nerve impulses. This is because it insulates the part of axons and reduces the chances of any disturbance in between due to the assemblage of voltage-gated sodium channels.
Therefore, increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.

how do infrared waves, uv waves,and microwaves affect us
Answer:
Here is your answer
Explanation:
Infrared radiation has a longer wavelength and lower frequency than visible light. Too much exposure can damage your eyes and skin. On a global scale, trapped infrared radiation contributes to global warming.
UV rays, either from the sun or from artificial sources like tanning beds, can cause sunburn. Exposure to UV rays can cause premature aging of the skin and signs of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis. UV rays can also cause eye problems.
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. But these types of injuries – burns and cataracts – can only be caused by exposure to large amounts of microwave radiation.

11. In which of the following examples will water move into the cells of the large intestine from the outside environment by the process of osmosis?
Osmosis occurs in the large intestine to transfer water from the feces into the neighboring cells.
What is the process of osmosis?Water is transported across cell membranes through diffusion and osmosis. The body reabsorbs absorbable solutes and electrolytes from meals (namely salt, potassium, and chloride ions).
The total solute concentrations and the permeabilities of the solutes in relation to water define the effective osmolality of a biological fluid, the large intestine to transfer water from the feces into the neighboring cells.
Water molecules move by osmosis across the cell membrane from a lower solute concentration to a higher solute concentration.
Therefore, osmosis, a kind of diffusion, is how water enters and exits the cell's large intestine to transfer water from the feces.

If you have a container with hydrogen atoms and oxygen atoms in it do you automatically have water?
Answer:
no
Explanation:
you have to have the right amount and the right situation for it to turn into water. for instance The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.

Explanation:
if correct brainlist?
Answer:
B. a group of connected or related things?
Explanation:
A system must have some form of relationship between the components inside of it. All these components work together to do a certain task or to run efficiently.
For example, let's take the court justice system. Inside the system is broken down into a range that can go from small claims court to the Supreme Court of the United States. This system is to ensure that their is not only a smaller burden on the supreme court to be able to take care more of national & international claims, but also so that if a citizen feel that they have a unfair ruling, they may bring it up to a different court that may not have local preferential to a certain degree.
All parts of a system is connected or related to each other, either as a cause, and effect, or a solution.
