1 kilometer = 6.68 × 
(<<<AU is in scientific notation here)
To convert 300 billion kilometer (3,000,000,000 km) into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 × )
3,000,000,000 × (6.68 × ) = 20.04 AU
Hope this helped!
Unfortunately this question is incomplete as it is a multiple choice question. The following options are provided:
<span>A) body cavity between body wall and digestive system
B) number of embryonic tissue layers
C) type of body symmetry
D) presence of Hox genes
E) degree of cephalization
The answer is D: presence of Hox genes
</span>
Hox genes are a group of genes that determine the basic structure and orientation of animals.

1. The energy left in the Quaternary consumer level is 0.06283 kcal.
2. 0.65 units of energy is still available at the tertiary consumer level.
<u>Explanation:</u>
Energy flow in an ecosystem obeys the ten percentage law According to which ten percentage of energy from a trophic level gets transferred to the next trophic level. In the given question plants belong to the trophic level , producers and it transfers 10 percentage of its energy to the primary consumer level.
In the question 1 the energy that the producers have is 628.3 kcal. Ten percentage of this i.e 62.83 kcal gets transferred to the primary consumer level. Ten percent of that which is 6.283 kcal gets transferred to the secondary consumer level. Ten percent of 6.283 kcal i.e 0.6283 kcal energy is transferred to the tertiary consumer level.
Thus the Quaternary consumer level gets ten percentage of 0.6283 kcal i.e 0.06283 kcal. In question B the initial energy at the primary level is 650 units. Ten percentage of 650 i.e 65 units reach the primary consumer level. Ten percentage of this 65 units then reaches the secondary consumer level. Thus the secondary consumer level has ten percent of 65 i.e 6.5 units of energy.
So the energy that reaches the tertiary consumer level is ten percentage of 6.5 i.e 0.65 units.
