Answer:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.Body structures can change according to the actions of the organism.have an innate tendency toward complexity and perfection. The actions of organisms as they use or fail to use body structures.
Protects brain and spinal cord from trauma, as well as supplies nutrients to nervous system tissue. It also removes waste from cerebral metabolism.
Answer
Option C - Skeletal Muscles
Explanation
Antagonistic pairs are the muscles that are functionally opposite, if one produces flexion, then the other's primary action is an extension. Skeletal muscles work in pairs to move a bone so that the muscles can function properly. They contract the bone making nerves deliver a message to the brain. For example. Biceps and triceps. The lower arm is moved upwards when the biceps muscle contracts and the triceps muscle is relaxed and vice versa.
Answer:
In an individual's molecular and cellular level, the heterozygote alleles are preferred over the homozygote alleles. In humans, the heterozygote alleles are found at a locus of beta polypeptide subunit of hemoglobin, while on the other hand, the homozygous alleles found at a similar locus are prone to sickle cell disease.
The individuals carrying homozygous alleles exhibit sickle-shaped RBCs and they also possess low oxygen-carrying capacity, which ultimately results in brain, kidney, or heart failure. However, in the case of heterozygous alleles, the configurations of RBCs are of two kinds, that is, normal shaped and sickle-shaped. Thus, there are not enough sickle-shaped cells to result in the condition.
The heterozygote alleles are resistant to malaria, thus, in tropical areas, where malaria is a prime issue the heterozygote alleles are preferred over the homozygote dominant alleles as they are vulnerable to the infection and over the homozygote recessive alleles who has sickle cell disease.
