Answer:
D
Explanation:
Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger significant in activating protein kinases.
Answer:
Tendon sheaths protect long tendons as they course over and around synovial joints.
Explanation:
Tendon sheaths are tubes of tissue filled with a lubricating fluid that surround the tendons like a tunnel. The tendon sheath prevents the tendon from fraying or being exposed to excessive friction. The inside of the sheath is lined with synovial fluid. This allows the tendon to slide forward and backward. From this we can say that the tendon sheaths protect the long tendons as they travel through the synovial joints.
<span>The birds with the longer beaks will be fittest in the environment post-drought because they will be able to gather resources (food) hence survive. This will enable these bords to reach reproductive again and pass down the genes. It is important to note that fitness in nature is determined by the capacity to reproduce.

<span>Natural selection will change the allelic frequency such that the allele for long neck will be more in the population while that of short beaks will reduce. This is because short beaks trait will not be able to reach reproductive age (due to starvation) because of the incapacity to gather food <span>resource hence their genes will keep reducing in the subsequent generations.

<span>Natural selection is a natural selective force that acts on a population and results to variation (differential) in the survival of the individuals in the population due to variations in phenotypes in the population. The most successful traits (phenotype that is best suited for the environment) are able to reach reproductive age, find a mate and reproduce hence leave its genes in subsequent generations</span>
Answer: <u>rTMS
</u>
rTMS uses magnets to stimulate the areas of the brain.
EEG uses metal discs which are attached to the scalp of the person, but these don’t provide any energy or input to the brain. So it is an incorrect answer.
EMDR uses movement of eyes to detect any symptom of trauma. Again, incorrect answer.
REBT is a kind of a psychological therapy, so it doesn’t use any device or instrument. So, it is a wrong answer.
Glucose is oxidized and co2 is reduced
