Answer: The given statement is False.
Gene ( segment of DNA that corresponds to particular protein) expression is a process by which a protein product is produced through transcription and translation of gene.
Gene expression is highly regulated process, which means that genes are only turned on whenever their protein product is required by the body ( for instance, insulin gene is turned on only when blood glucose level is high in the body).
Moreover, particular genes are activated in specific cells and other genes are turned off in order to make cell function in a specific way. Also, there are non protein coding genes in the cells that do not code for any protein.
Thus, given statement is False.
B) The effected neurons in the CNS regenerate gradually.
C) The path of impulses in the nervous system may be disrupted.
D) Both (A) and (B)
Answer:
The answer is c)The path of impulses in the nervous system may be disrupted
Explanation:
A spinal cord injury causes apoptosis of the oligodendrocytes found on damaged areas of the cord, several days or weeks later. The death of these oligodendrocytes is another serious consequence of the lesion, since these cells are what make up myelin, which is the one that envelops the axons, accelerating the direction of nerve impulses. This apoptosis causes axons that are still intact to lose myelin, which incapacitates the spinal cord to communicate with the brain.
B.) lower, decreased
C.) higher, decreased
D.) higher, increased
Doppler Effect is defined as the change of frequency of a sound or light wave produced by a moving source and a stationary observer. The waves when they move towards the object compresses.
The correct answer is:
Option B. lower, decreased
The Dopplereffect can be explained as:
1. The listener will have the impression that the moving source is higher in the pitch as it moves away from the listener.
2. The frequency of the waves will be decreased because the time between the successive sound waves is lengthened or increased.
Therefore, the pitch will be lowered and the frequency will be decreased.

The correct option is this: PLANTS CAN BE USED TO MAKE MATERIALS.
Plants are very important living organisms and they can be used in diverse ways. Some plants can be used as foods, some plants are used as raw materials for making pharmaceutical drugs and other herbal products. Plants, such as cotton are used to make clothing materials and dead and decaying plants serves as fertilizer that add nutrients to the soil.
B. absorbing water and minerals from undigested food
C. using muscle movements and enzymes to break down food
D. transferring nutrients from digested food to the bloodstream
Answer:
spinal cord and nerve plexus
Explanation:
Faced with this clinical picture, we would be talking about the affection of the spinal cord and the peripheral nerves that sensually perceive the areas of the epithelium, that is, they give the sense of touch, since the patient is diabetic, it could be deduced that the microangiopathies that this generates Chronic disease over time, can affect the irrigation of certain areas and therefore their inventions, due to lack of supply of oxygen and nutrients.
Diabetics are at risk of affecting both upper and lower limbs, because over time they lose the vascularization and winterization of these areas, thus generating infections or pain imperceptible by the patient.
On the other hand then, it would be ideal to say that the spinal cord with the peripheral nerves that innervate the affected areas, and the cerebellum are affected by the lack of balance or spatial disposition of the patient in relation to their body size.
