A cell is <span>the smallest structural and functional unit of an organism. It effects the body by making and strengthening tissue, fighting unwanted cells, and by giving off oxygen throughout the body.</span>
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.
Sixty-four (64) unique IP addresses could be made in a fixed length IP address system using 6 bits.
The IP address is a number assigned to any item that is connected to the internet. IP stands for Internet Protocol, it's function to work over a dynamic network. It is composed of two parts, it uniquely identifies a specific interface on the network.
