Identify the statement that describes the imperfection of natural selection. Identify the statement that describes the imperfect

ion of natural selection. Natural selection has not had sufficient time to create the optimal design in each case but will do so given enough time. Natural selection is generally limited to modifying structures that were present in previous generations and in previous species. In many cases, phenotype is not merely determined by genotype but by the environment as well. Though we may not consider the fit between the current skeletal arrangements and their functions excellent, we should not doubt that natural selection ultimately produces the best design.

almond37 [142]

Answer:

The correct answer is option C, that is, increase the concentration of the enzyme.

Explanation:

Biological molecules or proteins that enhance the rate of a chemical reaction taking place within the cell are known as enzymes. These proteins play an essential part in the proper functioning of the body, as they help in the process of metabolism and digestion.  

In the given case, if the enzyme gets saturated with the substrate, and is working at optimum pH and temperature, then to enhance the rate of the reaction the only thing that can be done is to enhance the concentration of the enzyme. However, further stimulation of some of the enzymes can be done with the addition of allosteric activators in the reaction, otherwise, enhancing the concentration of the enzyme is the only way.

Correctly match the following: - fibrous joint between radius and ulna - fibrous joint that unites bones of the skull - articula
topjm [15]

Answer:

- fibrous joint between radius and ulna: C. syndesmosis

- fibrous joint that unites bones of the skull: H. suture

- articulation between teeth and bone: J. gomphosis

- joint with a cavity between bones: E. synovial

- the epiphyseal plate: F. synchondrosis

- articulation between two pubic bones: A. symphysis

- permits opposition and reposition:  B. saddle  

- fibrocartilagenous fluid filled sacs outside the joint cavity: G. meniscus

- most common degenerative joint disease: D. osteoarthritis    

- movement of the sole laterally:  I. eversion  

Explanation:

The syndesmosis can be defined as a fibrous joint held together by ligaments. Sutures are fibrous joints of tissue that link the cranial bones of the skull. A gomphosis is a mobile fibrous that binds the teeth into sockets in the mandible and maxilla. Synovial joints are joints found between bones that move against each other (e.g., shoulder bones). They (synovial joints) are the most common class of joints found in the body. A symphysis is a cartilaginous, slightly movable, joint between two bones. A saddle is a synovial joint whose opposing surfaces are concave and convex, respectively. Osteoarthritis is the most common type of arthritis, this condition occurs when the protective cartilage surrounding the bones wears away over time. Finally, eversion refers to a type of movement of the foot which occurs in the auctioneering joint.
