Answer: Option B

Explanation: The cycle that maintains the balance of the earth is hydrologic cycle that makes sure to provide the water to all the living systems on earth.

The amount of water that is evaporated is equal to the amount of water that is precipitated on the earth. This continuous movement of water is known as hydrologic cycle.

The rock cycle is responsible for providing the minerals to the soil and other parts that require minerals.

all plants give out oxygen during day and carbon dioxide during 9 to you agree with this statement give reason​
ankoles [38]

Answer:

Yes, I agree with the given statement.

Explanation:

Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.

Lelechka [254]

Answer:

<h2>Coevolution</h2>

Explanation:

Coevolution : It is the influence of closely associated species on each other in their evolution, they affect each other.

In coevolution , two or more species reciprocally affect  evolution of  each other by natural selection.

 

Coevolution Examples:

There are lots of examples of coevolution, some are here

i) coevolution of Predator-Prey , this relationship is one of the most common examples of coevolution.

ii) coevolution of  Herbivores and plants,

iii)  coevolution of Acacia ants and Acacias and

iii)  coevolution of Flowering Plants and Pollinators and many others.

Correctly identify each of these definitions or examples as either depolarization or hyperpolarization of the plasma membrane. 1
natulia [17]

Answer:

  1. hyperpolarization
  2. depolarization
  3. hyperpolarization
  4. depolarization
  5. hyperpolarization
  6. depolarization
  7. depolarization

Explanation:

The resting membrane potential is balanced by ion leakage and ion pumping, to get an electrical signal started the membrane potential has to lose its balance. This starts with a membrane channel opening for Na+ since Na+ concentration is higher outside the cell, ions will rush into the cell. This will change the relative voltage inside the cell. The resting potential has a voltage of -70 mV, the sodium cation entering the cell cause it to become less negative. <em>This is known as depolarization.</em>

The concentration gradient for Na+ will continue to enter the cell making the voltage to become positive reaching +30 mV. At the same time, this happens, other voltage-gated channels are also opening, a concentration gradient acts on K+, as well, as it leaves the cell, it takes a positive charge with it making the membrane potential to move back to its resting voltage of -70 mV. <em>This is called repolarization. </em>

For potassium ions to reach equilibrium the membrane voltage needs to be below -70 mV, this leads to a period of <em>hyperpolarization</em> that occurs while the K+ channels are open.

I annexed an image that illustrates this action potential process.

<em>Considering the information given during depolarization there's an increase in the number of sodium leak channels (7) making the inside of the cell more positive (2) increase in the membrane potential (4), this also implies a decrease in the extracellular concentration of potassium (6)</em>

<em>Meanwhile, during hyperpolarization an increase in the extracellular concentration of potassium (3) decreases the membrane potential (1) making the inside of the cell more negative (5).</em>

I hope you find this information useful and interesting! Good luck!<em>       </em>
