marysya [2.9K]

Answer:

Indohyus is a fossil, found in 2007, of a chevrotain-like mammal believed by some paleontologists in the Evil Liberal Science Conspiracy to be a transitional form between land-dwelling mammals and the ancestor of whales.

1) A plant gets 628.3 kcal of energy from the sun, what energy is left at the quartenary consumer level?
Jobisdone [24]

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.

shusha [124]

Answer:

{\boxed {\sf Adenine \ with  \ Uracil}}

In RNA (ribonucleic acids), the nitrogen bases are:

  • Adenine
  • Guanine
  • Cytosine
  • <em>Uracil</em> (there is thymine in DNA, but not in RNA)

The bases pair like:

  • Adenine (A) with Uracil (U)
  • Cytosine (C) with Guanine (G)

So, the base pairs for RNA are <u>A with U </u>and <u>C with G</u>
