Answer:
0%
Explanation:
Achondroplasia is an autosomal dominant disorder that is expressed in both homozygous and heterozygous dominant genotypes. Since two affected parents have a normal girl child, both the parents should be heterozygous carrier for the disease. Let's assume that the dominant allele "A" is responsible for the disease. Genotype of both the parents of the girl would be "Aa". The genotype of girl with normal stature is "aa". Genotype of her normal partner is "aa".
A cross betwee aa X aa would get all the progeny with "aa" genotype. Therefore, all of their children would have normal stature and there is 0% probability for them to have a child with achondroplasia.
I think C, correct me if I’m wrong.
There are two types of polymers, which are natural and synthetic. Although natural polymers do not affect the environment, synthetic polymers do.Synthetic polymers are anything that is manufactured or influenced by humans. Due to this, these types of polymers release reactants which are hazardous; both to humans and the environment.Synthetic polymers, which include plastics, rubber, How do polymers effect the environment?adhesives, and Styrofoam cannot be degraded into the environment, causing a buildup of these chemicals all at once, causing a release of any "excess" chemicals into the environment.From there on, polymers create garbage loads, and chemical reactants that effect the environment, and spread around. Therefore effecting anything grown or eaten around it. This could call chemical poisoning to the greenery, animals, and living organisms around it. Not all polymers are bad. In fact humans are made up of polymers. But polymers from sources such as crude oil synthesized into plastics release toxins as they break down. When you burn plastics synthesized from crude oil feedstock, carbon dioxide and dioxins can be released into the air if smoke is not properly <span>What are the bad effects of polymers on your environment?filtered as they are in high quality waste-to-energy incinerators. Also plastics </span>are non biodegradable and so landfills are used to bury the plastic this takes up space and also costs money because there is not enough room for all the <span>waste. Therefore plastics are banned in some areas.

Well, wind and solar energy are good places to look at. The highest wind speed recorded in Antartica was roughly 199 mph, so they would definitely gain a large amount of energy from the wind. A smaller turbine can handle severe weather conditions, so setting some up along the most wind ridden places would be good. Solar energy would also be the best option since their days are longer than their nights over there. There can be days at a time where the sun doesn't rise at all, and then there are some where there is sunlight for a full 24 hours. So, it really depends on your preference, and the cons and pros of the energy type.
For wind: Set up a series of turbines along the areas that have the most wind. Turbines can withstand large storms. There is usually some kind of wind blowing.
For solar: Set up some solar panels where they would be able to get the most amount of sunlight. There are 24 hour long days of sunlight, but there are also some days where there is no sunlight at all.
Hope this helps you a bit.
Destruction of biodiversity. Water pollution depletes aquatic ecosystems and triggers unbridled proliferation of phytoplankton in lakes — eutrophication —. Contamination of the food chain.Human diseases: Pathogens(viruses,bacteria,fungi,protozoa etc)are biological pollutants of water. They cause typhoid,cholera,dysentery,jaundice,hepatitis.
