The rows of bushes

Explanation:

<em>The experimental unit in this experiment would be the rows of bushes in the field.</em>

<u>By definition, experimental units are considered physical entities that can randomly be assigned to varied treatment regimes during the course of a research.</u>

In this case, the entity that are given different treatment condition during the process of experimentation are the rows of berry bushes within one of the several fields. Half of the rows were covered with nets while the remaining half were left uncovered.

<em>The rows were given different treatments and hence, considered the experimental units in this particular experiment.</em>

The correct option is c.

Why the location and quality of food sources in the soil are sometimes likely to stimulate random movements by C. Elegans, but a
Kipish [7]

Answer:

The Caenorhabditis elegans dauer state is a hibernation-like state of diapause that displays a dramatic reduction in spontaneous locomotion.

Explanation:

Mutations affecting the neurotransmitter dopamine, which regulates voluntary movement in many organisms, can stimulate movement in dauers. The movement of quiescent animals is stimulated by conditions that reduce dopamine signaling and also by conditions predicted to increase dopamine signaling.The stimulation of movement by increased dopamine is much more pronounced in quiescent daf-2(−) dauer and dauer-like adult animals.

In C. elegans hermaphrodites, dopamine is produced by eight neurons and signals via at least four dopamine receptors, DOP-1 through DOP-4. In addition, a presynaptic reuptake transporter, DAT-1, removes dopamine from the extracellular space to terminate signaling. In C. elegans, dopamine is best known for mediating the “basal slowing response” in which the animal's movement slows when it encounters food..  Dopamine is thought to be released in response to food and to act on motor neurons to modulate the animal's movement . Animals that cannot produce dopamine fail to slow in response to food and exogenous dopamine slows the movement of animals cultured without food.The response to dopamine in this situation is complex, as the absence of specific dopamine receptors can have either positive or negative effects on movement.

What is the proper position of the erector spinae muscles situated from medially to laterally relative to the axis of the verteb
Kazeer [188]

Answer:

These group of muscles called erector spinae muscles arises from a tendon in the sacral area and pelvis, it extends up to the occipital bone.

Erector spinae muscles originates from the SPINOUS PROCESSES of T9-T12 of the thoracic vertebrae and inserts into the SPINOUS PROCESSES of T1-T2 of the cervical vertebrae

They therefore run vertically on either side of the spine (medially and laterally).
