1. If we compare the lengths, the good answer would be the neurons.

The body of the neuron measures from 5 to 120 μm. The size of a neuron (or rather an axon) varies from a fraction of a micron to two meters (the equivalent from the brain to the toe).

2. The particularity of neurons is that it does not divide, but survive for a very long time.

Neurons do not usually die before the death of the entire organism. However, many types of trauma and pathology can shorten the duration of their existence. Neurons that disappear and are rarely replaced (or not) because there are few stem cells that can differentiate into neurons in the mature nervous system. Like most cells, neurons can die in two different ways: necrosis or apoptosis.

According to Piaget, children have acquired the cognitive skill of conservation when they're able to
tatuchka [14]

Answer:

The question lacks options, the options are:

A. understand the viewpoint of other people.

B. realize that the term heavy describes an object one way and the term big describes it another way

C. understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

The answer is C

Explanation:

Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.

However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.

He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.

Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

This method can be used to sterilize a liquid media without
Lena [83]

Answer:

a. autoclaving

Explanation:

The autoclave is a device designed to sterilize contaminated material and media, in order to reliably eliminate microorganisms that would otherwise be present in objects that are used in diagnostic, treatment or research activities in hospitals and laboratories health institutions . This sterilization is usually carried out with moist heat in devices called autoclaves. It is also a widely used equipment in the food industries and in the pharmaceutical industry.

For sterilization of culture media to be effective, the selected temperature and time must be achieved throughout the liquid. Since the transmission of heat in the liquid of the vessels is carried out from the outside inwards, it is evident that the efficiency of the process will depend on the volume of liquid.

In general, it is not convenient to sterilize large and small containers together. In any case, the temperature and time will be selected according to the volume of the containers.

Hermetically sealed containers must be introduced into the autoclave without completely closing the cap, to facilitate the entry of steam during the process. When emptying the autoclave after sterilization we will proceed to completely close these containers.

Empty containers require a longer sterilization time than containers with liquid inside.

The autoclaves are available in many sizes, the small ones are desktop and the larger ones are complex equipment that require a large amount of pre-installation for their operation. In order to measure its size, the volume of the sterilization chamber is usually taken as a reference, which is measured in cubic centimeters or liters. Depending on their operation they are semi-automatic or automatic.
