Answer:

Velocity

Explanation:

Given the change in positive (direction) over time we are given the velocity formula.

V = Change in direction/Change in time

Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.

Suppose that a person takes a fall while hiking and develops tetanus when the pathogen enters through an open wound in their arm

qaws [65]

The tetanus infection is considered to be a Droplet infection.

<h3>What is Tetanus?</h3>

Tetanus is a neurological disease which is characterized by the occurrence of spasms in the muscle.

Tetanus can be caused if initial care does not take place after the wound occurs and therefore, it is very important to immediately take care of the wound.

To treat the wound tetanus immunoglobulin and tetanus toxoids are given to the person, however, it is necessary to give the two injections using different syringes and at different sites, because the immunoglobulin can cause neutralization fo the toxoid.

Thus, this could be the answer.

1. 1 Water makes up between 70-90% of the weight of most life forms, and nearly all chemicals present in living matter are solub

boyakko [2]

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.
