ANSWER:
THE THREE LAW OF MOTIONS ARE LAW OF INERTIA, LAW OF INTERACTION & LAWW OF MASS AND ACCELERATION
- Law of Inertia - An object at rest and an object in motion stays in motion with the same speed and in the same direction.
- Law of Interaction - For every action, there is an equal but opposite reaction.
- Law of Mass and Acceleration - The acceleration of an object as produced by a net force is directly to the magnitude of the net force and inversely propotional to the mass of the object.
<em>F= ma ; a=F/m</em>
<em />
wherein;
<em>F= Force (N)</em>
<em>m= mass (kg)</em>
<em>a= acceleration (m/s^2)</em>
Answer:
The correct answer is - Similar nucleotides are present in both fruit-fly and frog DNA.
Explanation:
Fruit fly or drosophila DNA sequence and DNA sequence of the gene of frog for a particular trait is combined and heated to separate the DNA strands by separating the nucleotides present between the strands of both organisms.
This is observed after cooling down the single strands after paired up that some of the DNA paired with the DNA. This is only possible if the DNA strands of the particular gene have similar nucleotides to form hydrogen bond in single strands of DNA of frog and fruit-fly.
<span>The question says, which of the following is not required by an animal to control body temperature. All these statements are true except D. The correct option is D. The fat in animals bodies keep them warm at all times and animals do not have to look for a source of heat to keep warm. They are able to regulate their body temperature internally. </span>
Answer:
The statement true about the Mercalli scale is "The scale rates an earthquake according to how much damage it causes."
Explanation:
The Mercalli Scale is a way to rate the earthquakes according to the level of damage at a given place. It got its name after the Italian seismologist Giuseppe Mercalli . The scale has 12 divisions. Lower numbers indicate intensity that is likely felt by people where as the higher numbers indicates the damage to structures and buildings. The ratings are given in Roman numerals. This scale is presently called as the MMI scale, or the Modified Mercalli scale.
