Answer:
The correct answer is tissue.
Explanation:
A group of cell which are specialized, similar in structure, and function together in a coordinated manner is known as tissue. There are different types of tissue present in animal and plant cells, for example, in animals the four types of tissue is connective, epithelial, nervous and muscle tissue.
These tissue comes together to form organs like heart, brains, kidney, etc. Two or more tissue types can make an organ. Different tissue performs a different function. For example, nervous tissue helps in transferring nerve impulse, connective tissue connect different tissue. So the correct answer is tissue.
Catalysts help drive and speed up chemical reactions.
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.
Answer:
E. only the first and second choices
Explanation:
Small animals often have smaller habitat ranges than other larger animals.
This means they have fewer places where they can survive, needing some specific environmental conditions. More specific than some bigger animals.
Small animals often have more specialized requirements for living than larger animals.
Some little changes in temperature or weather can affect a lot to some small animals and can not affect bigger ones.
