These changes occur due to increased heart rate (measured by taking pulse) without maintaining his normal blood pressure is suggestive of reduced stroke volume. Both drop in blood volume and a weakened heart could cause this, however, the chest pains suggest heart damage. Failure of compensating mechanisms to maintain blood pressure suggest a serious decline in cardiac output.
Answer:
Nonhuman life in an urban ecosystem differs from that in an undeveloped forest ecosystem
Explanation:
Diffusion<span> in </span>cells<span>. Materials like oxygen, carbon dioxide and glucose enter and </span>leave cells by diffusion<span>. When a </span>cell<span> is respiring the concentration of oxygen and glucose inside the </span>cell<span> is lower than the surrounding blood so these </span>substances<span> move into the </span>cell<span>.

Answer:
Father - AO
Mother - AO
Baby - OO
Explanation:
This question involves blood type in humans where blood types A and B are dominant over blood type O, but A and B codominant. In this blood group system:
- Genotypes AA and AO are phenotypically type A
- Genotypes BB and BO are type B
- Genotype AB is type AB
- Genotype OO is type O
According to this question, a man with type A blood marries a woman with type A blood. They have their first child as type O blood. This means that both parents of this child are heterozygous type A i.e. AO and AO. This is the only way the parents can have a child with type O (genotype OO). Hence,
Father - AO
Mother - AO
Baby - OO
