Reproductive isolation is due to geographical isolation like mountain river etc in reproductive isolation there is no flow of genes from one population to another
Therefore REPRODUCTIVE ISOLATION leads to {SPECIATION }
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.
This is an example of a substitution mutation. Substitution means changing a base pair in a codon, with another base pair. For example, in this case, Thymine was replaced with Adenine. In Deletion, insertion, and copying, a change in the base pair occurs due to deletion, addition or copying of base pair itself.
Answer:
Despite a substantial literature using life cycle assessment (LCA) approach, the extent to which second and third generation biofuels are more sustainable than the first generation remains a subject of debate. Although the existence of limitations due to LCA variability and uncertainty, this paper intends to determine global tendencies based on a statistic and critical interpretation of previously published study results, reviewing 61 recent papers addressing an environmental evaluation of microalgae biofuels. Such information is compared to the same impact indicators for fossil fuels and for ethanol and biodiesel from terrestrial crops in Europe and Brazil. For each case, the system boundaries and the methodological choices were precisely described. The sustainability potential of all biofuels was evaluated by the Global Warming Potential (GWP), the Energy Ratio (ER) and the Land Use (LU), allowing a broad estimation of the biofuels’ contribution to climate change mitigation, their net energy efficiency and their competiveness with food production chain.
Explanation:
Answer:
C. depth C
Explanation:
From the chart you can teel that the most dense, coolest and saltiest waters can be found at the deepest levels of depth, in this case the deepest from the options would be located at less than 3,000 meters and it would be point C. As we know as we go depeer into the water of the ocean pressure increases and with that density of the water also increases, under normal circumstances the sunlight and sun heat is the only thing that is able to heat up the water of the ocean, so the deeper you go, the less sunlight and less sun heat is available so the waters become cooler.
