<span>Answer: Imagine a very simple neural network, with four neurons. Each neuron is connected to three other neurons in this example. Therefore, the total number of neuron connections is going to be 12 in this example.
We're comparing this to a DNA molecule that is 12 bp long. Effectively, we can say that the DNA molecule is able to store 12 bits of information. The information the neural network can store however is basically a function of how many different firing patterns there can be. It's easy to see how that's a lot bigger than 12.</span>
It has four heart chambers, just like birds and mammals.
Answer:
b. enables cell to recognize and respond to external environment
Explanation:
There are two types of receptor present in/on the cell. The receptors that are present on the cell surface are called the cell surface receptor and the receptor which is present inside the cell is called an intracellular receptor.
The cell surface receptor is responsible for enabling the cell to recognize and respond to the external environment. The signal molecules that bind to the cell surface receptors are mostly hydrophilic and they generate an intracellular cascade in the cell which brings specific changes in the cell. So the right answer is b.
