Explanation: Natural selection is a cause of evolution. So over time, organisms can start to evolve due to artificial selection. Natural selection, sometimes referred to as "survival of the fittest," is a mechanism for the evolution of a population to become better adapted for survival in a specific environment. This means that organisms with traits that are best suited for the environment will pass these traits to their offspring.
The answer is high. It is because bipolar disorder does
cause high rate of heritability because of factors that could affect the
individual. These factors or biological cause can affect greatly in which is
why it has been concluded that it could cause high heritability. The factors have been a great contribution in making an individual to be susceptible or acquire this type of disorder.
An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
<h2>Upper limb,Pectorial girdle and Axial skeleton</h2>
Explanation:
Upper limb-
The muscles of the upper appendage can be divided into 6 distinct areas such as <em>pectoral, shoulder, upper arm, front lower arm</em>, <em>back lower arm, and the hand</em>
There are 4 muscles of the pectoral locale <em>pectoralis major, pectoralis minor, serratus foremost and subclavius </em>
Pectorial girdle-
The <em>shoulder </em>girdle <em>or pectoral </em>girdle is the arrangement of bones in the attached skeleton which interfaces with the arm on each side
In many of the it comprises of the <em>scapula and clavicle</em>
In many <em>species have three bone found in the shoulder, it connected of the coracoid and clavicle and scapula</em>
Axial skeleton function-
The pivotal skeleton underpins and ensures the <em>mind, spinal rope and huge numbers of the interior organs</em>
It likewise gives locales to the connection of different bones and muscles in the body and shields the nerves and veins from the <em>cerebrum and spinal line.</em>
