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.

Answer:
Biogenesis = <u>Life from life</u> : Spontaneous Generation = <u>Life from non-living things</u>
Explanation:
As an accurate statement of the difference between spontaneous generation and biogenesis:
Spontaneous generation that sometimes refers to "abiogenesis" is an idea that life comes from non-living things/components. Whereas biogenesis is a contemporary concept that life can only arise from another living thing.
Cell division, a baby of mice born from adult males and females, etc. are some examples of biogenesis. In contrast, there is no example of spontaneous generation. It remains a theoretical concept.
Answer:
the correct answer is enzymes
Explanation:
enzyme act as catalyst and is a biological molecule which within the cell membrane can speed up or increase the rate of biological reaction without affecting itself and is obtained unchanged at the end of reaction
