Explanation:
Answer:
It has an anterior and posterior face. The greater tubercle serves as attachment site for three of the rotator cuff muscles – supraspinatus, infraspinatus and teres minor – they attach to superior, middle and inferior facets respectively. The lesser tubercle is much smaller, and more medially located on the bone
Answer:
The progeny produced is 100% heterozygous individuals.
Explanation:
Remember that in Mendel crosses, there are two alleles for each character, in this case for the color of the flowers.
When the problem refers to pure varieties, it refers to individuals with two equal alleles for the same gene.
If two pure varieties with antagonistic characters intersect, 100% of heterozygous individuals will be obtained in the offspring.
As for its phenotype, it will depend on which allele is dominant over the other.
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.
