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.

Answer:

its B

Explanation:

The incident that happen before a chemical reaction can begin the activation energy must be reached. Thus, option B is correct.

The extra energy is the minimum amount of extra energy which required by reacting molecule to convert into the product.

Factor at which activation energy depends are as follows:-

1: Activation energy depends upon the nature of reactant if reactant is ionic then required activation energy is less and if reactant is covalent then required activation energy is high.

2: Nature of catalyst if catalyst is positive then required activation energy is less and if catalysts is negative then required energy is high.

3: Activation energy doesn't depend on pressure, temperature, volume etc.

Temperature is one the important factor at which any reaction is depend. In any reaction if temperature is increases the rate of reaction is increases and if temperature is decreases the rate of reaction is decreases.

Here, is the Arrhenius Equation  which shows the temperature dependence of the rate of a chemical reaction.

k=Ae^−EaRT

Where,

k= rate constant of the reaction

A= Arrhenius Constant

Ea= Activation Energy for the reaction (in Joules mol^-1)

R= Universal Gas Constant

T= Temperature in absolute scale (in kelvins)

Therefore, The incident that happen before a chemical reaction can begin the activation energy must be reached. Thus, option B is correct.

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.

Answer:

cells are made of organelles

Explanation:

because it is why the cells has different kinds

Osmosis occurs in the large intestine to transfer water from the feces into the neighboring cells.

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.

Answer:

Myelin sheath

Explanation:

Increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.

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.

II. the textures of organs

Explanation:

A human torso model is designed to be as accurate as possible so that students/researchers can understand the inner workings of the body. Therefore, the organs have been designed to be the same size of an actual human being of that stature, while also being in the correct position within the body to better understand the interrelationships between the organs. The only thing that is not accurate in these models is the texture of the organs as most are smooth plastic unlike the actual organs.
