The organs are known as Vestigial organs. The evolution from land-dwelling animal to the marine animals has led whales as well as dolphins, to lose hind limbs. The pelvic and leg bone serves no purpose in them and just provide the anchorage to muscles
Hey! here is your answer
passive refilling of the heart occurs During ventricular systole, the blood pressure
<span>A human body is composed of muscles. Without it, the human body cannot function and will die. </span>
There are three types of muscle tissues: Skeletal muscle, Cardiac muscle, and Smooth muscle.
The skeletal muscle aids in the movement of the human skeleton. The 600 skeletal muscles make up 40 % of our body weight and are reliant on the signals released by our nervous system to start moving.
<span>Cardiac muscles are those muscles which encloses our hearts. They are involuntary muscles which pumps blood throughout our bodies by creating steady and rythmic pulsing. They also make our heart contract by producing electrical impulses. </span>
<span>Smooth muscles are found in the walls of blood vessels, respiratory passageways, and hollow organs. Its contracting movement is wavelike and it helps in the transfer of food through our stomachs or urine through our bladder. </span>
<span>These muscles responds to nerve impulses and other stimuli.</span>
Answer:
Has the genetic disorder
Explanation:
Recessive gene are genes that are expressed phenotypically only in the homozygous condition. Homozygous is a condition where an organism contains identical alleles in homologous chromosomes. When a person is homozygous recessive for a recessive genetic disorder, then this genotype means that person has the genetic disorder since they have the identical allele.
It was exposed to oxygen. This is called oxidation and it's a chemical reaction, meaning it can't be reversed.
