Answer:
Because A does not equal T, and G does not equal C, this cannot be a double-stranded DNA molecule. It must therefore be a single-stranded DNA.
Explanation:
The base composition in the observed DNA sample does not follow the Chargaff rule. If it was a double-stranded DNA, the percent proportion of adenine base and thymine base should be equal (either 30% or 20% for both). Similarly, the percent proportion of guanine and cytosine bases must also be equal (either 30% or 20% for both). Since the given sample does not follow it, it is not a double-stranded DNA molecule but is present as a single strand.
Explanation:
El Nino occur irregularly approximately every two to seven years. Warm water generally appears off the coast of South America close to Christmas, and reaches its peak warmth in the eastern Pacific during the late fall of the following year.
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.
