Question: Describe how a single amino acid substitution causes hemoglobin molecules to stick together. Use what you know about the structure of Hb and HbS, the properties of glutamic acid and valine, and how hydrophobicity causes molecules to behave in water.
Answer:
A Single amino acid must be polar to attract, just like water.
Explanation:
Sickle cell is an genetic illness and it is began by a alteration that arises in the beta sub units of the haemoglobin. Haemoglobin is a tetrameric protein made up of 2 alpha sub units and 2 beta sub units and it is the important part of the blood accountable for oxygen passage. Sickle cell is a illness that consequences from a replacement of a polar amino acid identified as glutamate with a non polar one valine at site six of the beta polypeptide component of haemoglobin. The replacement occurs as a consequence of a alteration in one of the bases in the beta-globin gene from adenine to thymine . As a outcome of this change, the beta polypeptide chains convert sticky in low oxygen circumstances since the valine sticks out of the chain and interrelates with neighboring non-polar amino acids.

increasing production of cheap calories of Sugar and Triglycerides for use in food products
The attempt by farmers to maximize profit prompted them to give hormones e.g streroids to animals to increase their biochemical reactions therefore the the products yields e.g they are giving steroids to poultry to improve chicken, eggs production;and to cattle for improved beef and milk production.
In order to obtain maximum sugar and fats productions, cheap calories forms of there are being produced. e,g fructose, maltose. if maltose is consumed in excess it leads to obesity, while fructose increases the level of cholesterol.These products requires a lot of processing with different chemical products which leads to health problems after consumption
Explanation:
Alright hopefully this isn't to confusing but, Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Also most living organisms carry out "glycolysis" as part of their metabolism. Last but not least, the process doesn't even use oxygen it takes place in anaerobic conditions.
Answer:
In the explanation. :)
Explanation:
Human powered generators are the best source for the rescue team. We cannot always depend on the sun. What if the sun is not out that day? What if it's a rainy day? What if the sun is what's causing the rescue team to come out? Human powered generators are sometimes untrustworthy, but at the same time we know that at least it's a step away. We don't have to wait all-day for the sun to help out. Of course, the energy from the sun is always going to be there and won't cause anybody hurt, harm, or danger, but at the same time we can always convert to human powered generators and they'll work just as perfect.
Hope this helps, have a great day!
If they are both carriers , we can create a cross with Rr.
The probability of not even carrying PKU is 1/4 or 25%
The probability of carrying is 2/4 or 50%
And the probability of inheriting the disease PKU is 1/4 , 25%
