Modelling uncertainty limits the accuracy of model predictions. Coral bleaching occurs because the seawater temperature is increasing. This is primarily because of climate change. Predicting climate change in the future is highly uncertain, as it is basically long-term weather prediction that depends on certain carbon emission scenarios. It is well known that normal weather prediction becomes inaccurate after around 14 days, so predicting long-term climate in the next 100 years or more is highly uncertain. There are a multitude of global circulation models (GCMs) that have been developed by different countries, all of which tend to predict widely different climate. Added to this uncertainty is that GCMs work on large spatial scales, and a technique called downscaling is used to predict more localised climate change. Since there are several ways of downscaling, this adds an additional level of uncertainty. Finally, we cannot be sure what carbon emissions will be released to the atmosphere in the future that will drive climate change, another source of uncertainty.
The phenomenon of populations of organisms changing from generation to generation is known as biological evolution.
<h3>What is biological evolution?</h3>
Biological evolution is a scientific term that deals with the change in inherited traits through successive generations in an organism's population. For example, penguins have typical wings over swim-friendly flippers which were there for many generations. It is also called microevolution. Biological evolution is important because it helps us to understand why an organism is the way they are. Mutation, genetic drift, gene flow, and non-random mating are some of the causes of biological evolution. Heredity and Reproduction are the top conditions for biological evolution.

Purple is dominant to white flowered.
Purple gene(which occurs in pairs of PP which are both dominant alleles) crossed with a recessive pp(white flowered) after crossing, all the offspring had Pp. Purple being dominant suppressed the white(p).
after crossing the offspring, (Pp and Pp) a quarter the offspring lacked the dominant allele P hence allowing the recessive colour white to be shown.
The MRI shows every slice of the brain, a CT shows circulation, possibly the outside of the brain.
Answer:
CAT ATG TAC
Explanation:
Adenine (A) pairs with Thymine (T)
Cytosine (C) pairs with Guanine (G)
And vice-versa
