Answer:
Inhibitors of cyclin-dependent kinases might play a role in regulating the concentration of cyclin in the cell cycle.
Explanation:
The presence of inhibitors of cyclin-dependent kinases has a great importance because it controls the concentration of cyclin that is necessary for the cell cycle. If inhibitors of cyclin-dependent kinases is absent , the amount of cyclin increases in the cell formation and cause a great damage to the cell cycle and the cell which is produced is abnormal or other irregularities.
Inhale and exhale because you inhale the oxygen and exhale the carbon dioxide
Answer: Somatic nervous system
Explanation:
The voluntary nervous system or somatic nervous system the part of the PNS (peripheral nervous system) which is associated with the voluntary control of the body movements.
These movements are generally controlled by the skeletal muscles. It helps in various movements such as walking, bending, sitting, et cetera.
This nervous system consists of the efferent nerves and afferent nerves or we can say motor nerves that helps in controlling the movement of the body.
<span>The correct answer for the question is D. Pine needles developed as a result of a beneficial mutation that increased the survival of plants the survived to reproduce and would then pass on the beneficial mutation to its offspring. Pine needle is the needle like leaf of a pine tree. This possible origin of pine needles from primitive narrow-leafed plants is an example of natural selection. Mutations changes the sequence of amino acids in a way that the phenotype expressed will give the organism advantageous characteristics. </span>
Explanation:
Frederick Griffith experimented on the Mice with the streptococcus pneumoniae strains. The virulent strain was called S strain smooth strain as it has a smooth layer whereas the avirulent strain was called the R strain or rough strain.
When he injected the virulent strain of bacteria by heat killing them and live R bacteria, he found that the mice were killed.
This shows that the live or avirulent bacteria became virulent or transformed into virulent bacteria by acquiring the virulent trait of the S bacteria. This led to the formation of the transforming principle.
