Answer:
Explanation:
Geneticists use letters to represent alleles of different characters.
(Alleles: one of the two or more alleles of a character.)
A single letter is used to represent both the alleles of a particular character.
A capital letter represents a dominant allele, while a small letter represents a recessive one.
<u>The letters do not just have one standard representation</u>. same letter can be used to represent different characters. However, the letters may relate to the allele. For example: the letter 'B' can be used to represent Brown eyes.
In human blood, there is a compound inside the RBCs called haemoglobin which ensures that the muscle will receive enough oxygen during exercise.
<h3><u>Explanation:</u></h3>
In human blood, the red blood corpuscles contain the haemoglobin. Haemoglobin is a iron chelated compound containing porphyrin ring and a globin tail which can establish co-ordinate covalent bond with both oxygen and carbon dioxide. The bonding element depends on the concentration of these two gases. In lungs, where the oxygen concentration is more than carbon dioxide, the haemoglobin bonds with oxygen and brings it to the tissues where carbon dioxide concentration is more. This makes the haemoglobin to release oxygen and bond with carbon dioxide which is brought back to lungs. This is the process by which each and every tissue including the muscles recieve oxygen.
In muscles there is Myoglobin which is another iron-porphyrin compound which has several times more affinity for oxygen than haemoglobin. This helps to extract more oxygen from haemoglobin in muscles.
I believe Enthalpy is the scientific term for the changes. The specific changes each item listed undergoes is hard to say correctly without knowing the options. Could you list the answers to choose from so I can get a better understanding of what they want in the answer?
Answer:
1.) Stimulus ----> A change in the system or environment.
2.) Response ----> A result or event that occurs because of a change in the system.
3.) Positive Feedback ----> The goal is to amplify the response until the stimulus is removed.
4.) Negative Feedback ----> The goal is to reduce the stimulus and return to homeostasis.
