Answer:
Abiotic factors are important to all organisms, because they make photosynthesis happen which is needed for plants to live to make oxygen, and oxygen is needed for humans to live. Water can easily be called the lifeblood of Earth.
Explanation:
Abiotic factors are important to all organisms, because they make photosynthesis happen which is needed for plants to live to make oxygen, and oxygen is needed for humans to live. Water can easily be called the lifeblood of Earth. All living beings, whether they are animals or plants, need a definite percentage of water present in their body to remain healthy.
Answer:
The Kinetic energy of the 6kg cart moving at a speed of 2 m/s at the bottom of the ramp is 12 J
Explanation:
Given:
Mass of the cart = 6 kg
Speed with which the cart is moving = 2 m/s
To Find:
The Kinetic Energy = ?
Solution:
The Kinetic Energy of the object is given,
![K.E= \frac{1}{2} m v ^2](https://tex.z-dn.net/?f=K.E%3D%20%5Cfrac%7B1%7D%7B2%7D%20m%20v%20%5E2)
where
m is the mass of the object
v is the velocity of the object
Now substituting the given values
The Kinetic energy of the 6kg cart moving at a speed of 2 m/s is
![= \frac{1}{2} m v ^2](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20m%20v%20%5E2)
![= \frac{1}{2} (6) (2)^2](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%286%29%20%282%29%5E2)
![= \frac{1}{2} (6)(4)](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%20%286%29%284%29)
![= \frac{1}{2}\times (24)](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%2824%29)
![= \frac{24}{2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B24%7D%7B2%7D)
= 12 J
Answer: from east to west
Explanation:
They ensure they leave the system and they also ensure that people get the nutrients they need.
Depolarization and Hyperpolarization occurs when ion channels open and close.
Explanation:
In some specific part of the membrane of neuron, the potential of the membrane becomes less positive it is that results in Hyperpolarization. Depolarization is in contrast with this, since the potential of the membrane will become less negative in this type. these two types occurs during the opening and closing of ion channels that are present in the membrane. This will result making the ions either entering the cell or exiting the cell.
hyperpolarization occurs when the channels opens and resulting in letting the ions that are positive to exit out of the cell. When the channel opening results in letting the positively charged ions to get into the cell, then depolarization occurs. The channel opening and closing highly depends on the binding nature of the molecules that are signalling.
