<u>Answer:</u>
<em>A law is a statement of fact but a theory is an explanation.
</em>
<u>Explanation:</u>
<em>A law is in general a universally accepted fact.</em> It remains true and the same in any part of the world it takes several years of experimentation to develop a law.
<em>A law is a statement that cannot be challenged at the present point of time with all its technological advancements.</em> A theory is different from a law. It is an explanation of facts.
<em>Most acceptable one among several explanations becomes a theory. A theory doesn’t have a universal nature like that of a fact. </em>
D. Ligaments are strong and flexible bands of connective tissue that holds bones together meeting at a point known as joints. The first option - tendons - is also a connective tissue but they attach muscle to the bone.

Answer:
Predator-prey relation.
Explanation:
A predator is defined as an organism that hunts another individual, whereas a prey refers to the organism that is eaten by the predator. They tend to co-evolve (evolve together). <u>The prey is essential for the predator to survive, while the predator controls the prey populations by hunting some of the individuals.</u>
Predator-prey relations are interactions that occur between two species where one species (prey) represents a food source for the other species (predator).
The turtle (prey) is essential for the survival of the jaguar (<em>Panthera onca)</em>, while the jaguar controls the populations of turtles by preying upon them. Therefore, this is a predator-prey relation.
Answer:
12:3:1
Explanation:
<em>The typical F2 ratio in cases of dominant epistasis is 12:3:1.</em>
<u>The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus</u>. There are different types of epistasis depending on the type of alleles that are interacting. These include:
- Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.
- Other types of epistasis include <em>recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).</em>
