Marianna [84]

Answer:

Answered below.

Explanation:

The fossil records are beneficial in giving us. wide range of knowledge about fossils but sometimes these records are flawed, in that they are incomplete or misleading.

Many of the fossil records available are incomplete because some animals tend to decay within a short period of time due to their soft tissue. Also some are destroyed due to the movement of tectonic plates over time.

Another flaw scientists encounter is that there are no fossils which illustrate or represent the orderly transition from one organism to another. Fossils generally do not support the Darwinian theory of evolution as no evidence is found of ordered, sequential transition from simple to complex life forms as postulated.

These flaws are significant because they influence our knowledge and understanding of life forms and evolution.

When a person is exercising the body needs to deliver increased amounts of oxygen to the muscles. Which componentes f the blood
ad-work [718]

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.
