Answer:Covalent bonds link carbon atoms together in long chains that form the skeletal framework for organic molecules. These carbon skeletons may vary in: ... Compounds with the same molecular formula but with different structures and hence different properties. Isomers are a source of variation among organic molecules.
Explanation:
<span>It means two things. One is that it attacks all foreign bodies, it's not specific to just one type of foreign bodies, and the other is that it's inborn and innate, meaning that you have a defense mechanism since birth, it's not aquired during life. If you're born without it you have to live in a bubble more or less.</span>
Answer: WAGGLE DANCE is the dance that provides honey bees information about both the direction and distance of food.
Explanation:
Honey bees are flying insects that helps in the pollination of plants as they collect nectar and pollen from plants for food. As the name implies, they are known for the production of honey.
The honey bee dance helps in social organization of the honey-bees which is established by the living of all individuals within the colony and they show the mutual cooperation among the members of the colony, and exhibit the overlapping generations.
WAGGLE DANCE is the dance that provides honey bees information about both the direction and distance of food for the colony. It consists of two phases:
- the WAGGLE phase and
- return phase which occurs in a regular alteration pattern by foragers. It involves running through a small figure-eight pattern.
The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
