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.
Warmblood mares that were pregnant (n = 10) had their peripartum alterations in blood pressure, heart rate, complete blood count, plasma electrolyte concentrations, and heart rate variability (HRV) assessed.
<h3>What is Gestation ?</h3>
The time during which an embryo, and eventually a fetus, develops inside viviparous animals is known as the gestational period. Although certain non-mammals also experience it, it is usual for mammals. When mammals are pregnant, they may have one or more gestations concurrently, as in the case of multiple births.
<h3>What is peripartum period ?</h3>
The time just prior to, during, and soon following childbirth.
Everyone agrees that the postpartum period starts when the baby is born. Although the end is less well defined, it is sometimes thought to occur six to eight weeks after delivery because by then the effects of pregnancy on many systems have essentially gone back to their pre-pregnancy states.

The answer is A
Explanation: don’t mind the volume, look at the surface area-to-volume ratios because they affect the efficiently of a cell to obtain nutrients and eliminate waste.

Answer:
Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros and φύλλον, phyllon. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light.
