<span>Venus goes around faster than Earth, so its period must be less than Earths 1.0 years. That eliminates the first two answers. My recollection is that T^2 = k r^3, relating period of orbit to radius, so T should be (0.72/1.00)^3/2 = 0.61 of the Earths period, so 0.62 is ans. </span>
The correct answer is D. 1.55 hm
We need to convert dm to hectometers,
We know that,
1 decimeter = 0.001 hectometers
1 dm = 0.001 hm
Using this conversion we get
(1550 × 1) dm = (1550 × 0.001) hm
1550 dm = 1.55 hm
It means 1550 dm can expressed as 1.55 hectometers.

Answer:
reproduction
Explanation:
A living thing is characterized by its ability to perform certain functions including growth, irritability, reproduction, respiration etc. Of all these characteristics, REPRODUCTION is key to the survival of an organism's species.
An individual organism will definitely survive without reproducing i.e it will continue living and undergoing its day-to-day activities. However, in order to ensure that its species amongst others survive and not be EXTINCT, it has to reproduce. Reproduction gives rise to more of the same species of organism to form a POPULATION.
