<span>Research suggests that high dietary intake of omega-3 fatty acids by pregnant women may be related to higher iq levels among children. DHA, otherwise known as docosahexaenoic acid is found in omega-3 fatty acids and it helps with the development and function of a baby's brain. It improves learning ability and it can be found in foods such as breast milk, eggs or fatty fish.</span>
It depends on the organism, they all vary, they can reach up to 90% but I’m not sure so pick C:70%
Magnetic force - B.
Electrical force - A.
Gravitational force - D.
Contact force - C.
<h3><u>Explanation:</u></h3>
When a charge moves about its path, it produces a magnetic force around it. This magnetic field is perpendicular to the axis of movement of the charge and is directly proportional to the amount of charge, speed of the charge, and inversely proportional to distance between the charge and the point of measurement. Michael Faraday discovered this phenomenon.
Electrical force of attraction or repulsion is seen between the two charged bodies, or one charged body and one uncharged body which can induce charge to the uncharged body. The attraction or repulsion between the charged bodies are seen if the bodies are close enough, and this is called electrical force.
The gravitational force is also a non contact force that is seen between two bodies which is always attractive in nature and is seen between any two bodies.
A contact force like friction is a type of force that takes place only when two bodies are in contact with each other.
I believe the correct response is the third option. Have higher resolution that allows you to view smaller specimens.
