Katie will use the black, red and purple balls in a ratio 1:2:1 for carbohydrate molecules.
There are four macro molecules in existence, these are carbohydrates, proteins, fat and oil and nucleic acids. All these molecules has carbon in their compounds. The carbohydrate is made up of the elements carbon, hydrogen and oxygen in the ratio 1: 2: 1, thus, the molecular formula of carbohydrate is C6H12O6.
Answer:
In terms of shared derived characteristics, the lophotrochozoan clade have an evolutionary novelty that is unique to it.
In terms of homology, the lophotrochozoan clade are Monophyletic, i.e they are made up of an ancestral species and all of its descendants. All are similar in characteristics resulting from a shared ancestry.
In terms of homoplasy, the lophotrochozoan clade have similar area correspondence between the parts or organs of different species acquired as the result of parallel evolution or convergence.
Answer:
The given statement is false.
It is because the greenhouse effect is a natural process which takes place in the environment by its own.
The greenhouse gases trap the heat energy coming from the sun and the energy which is radiated from the earth and helps in keeping the earth warm.
Natural processes such as volcanic eruptions, cellular respiration, forest fires, transpiration, decomposition et cetera produce greenhouse gases such as carbon dioxide, water vapors, methane et cetera.
The activities of humans increase the effects of the greenhouse effect however, they are not the sole reasons for this natural effect.
Bacteria or fungi were the first organisms know to mankind till This day
