Which example illustrates that individuals' lives are not entirely shaped by social structures?
Law Incorporation [45]

To illustrates that individuals' lives are not entirely shaped by social structures. Oprah Winfrey was born into poverty but rose to become one of the wealthiest people in America.

<h3>What are social structures?</h3>

The social structure. social structure is important from a sociological perspective because it influences how we behave. It can refer to a group's typical patterns, such as the relationships between men and women or students and teachers. Class Social. according to income, level of education, and standing in the field. Status.

Gender roles, the incest taboo, religious and healing rituals, mythology, marriage, language, art, dance, music, cooking, games, jokes, sports, birth and death because they involve ritual ceremonies as an accompaniment, etc. are examples of elements that may be considered cultural universals.

People learn how to function effectively in a society through a process known as socialisation.

When restraining a horse for a routine veterinary procedure, it's appropriate for the veterinary assistant to?
krok68 [10]

When restraining a horse for a routine veterinary procedure, it's appropriate for the veterinary assistant to Hold the horse's lead rope.

Holding the horse's lead rope is necessary, when restraining a horse for a routine veterinary procedure by the veterinary assistant.

Always hold the lead rope in the right hand by coiling the excess rope on the hand in the other hand.

Lead the left shoulder of the horse with the assistant's right hand with the excess of rope in the left hand of the assistant to avoid serious injury when the horse decides to bolt.

It becomes important to stable the horse by calming the horse before the routine veterinary procedure.

A leather band should be used in the rope by being tightened behind the legs of the front and by further fastening.

Remember not to harm the back of the horse by excessive fastening.

An example of vesicle-mediated transport would be:
WITCHER [35]
An example of vesiscle-mediated transport would be cell secretion by exocytosis.

The reason why this would be an example of vesicle-mediated transport is because all the other types of transport listed here are not something you would call vesicle-transport; the substances don't really get transported in vesicles. This is different in exocytosis where the compounds gets packaged into vesicles.

When a singly ionized potassium ion moves through a channel in the membrane passing from the outside to the inside, what is the
Korolek [52]

The magnitude of the work done by the electric field of the membrane is <u>W = 1.28 × 10⁻²⁰ Joules</u>.

We start with the necessity to take into account a value for the voltage present there in order to solve this problem by first considering that the membranes have two layers, one internal and one external, each responsible for producing a potential difference between the two levels.

As a result, in order to find a solution, it is necessary to take into account the potential difference between the two surfaces. In this instance, we'll assume a particular value for the load, but the recipient is free to substitute a different value if they prefer.

The product of the potential difference and the charge is used to define the work that an electric field performs. The charge of the potassium ion will be equal to that of its electron, so,

q = 1.6 × 10⁻¹⁹ Coulombs

Then the Work would be:

W = Vq

Here,

v = Potential difference

q = Charge

The 80mV potential difference we will have is quantified as follows:

W = (80mV (1V/1000mV))( 1.6 × 10⁻¹⁹ C)

W = 1.28 × 10⁻²⁰ Joules is the amount of work that the membrane's electric field has produced.

How does photosynthesis help to maintain homeostasis in plant cells?
viktelen [127]

Plants maintain homeostasis by keeping their stomata open just enough to allow photosynthesis to take place but not so much that they lose an excessive amount of water.

When plant cells use the food they make, the cells respire, taking in oxygen and giving off carbon dioxide.

- Hope this helps
