Based on selective permeability, if the pores in the dialysis tubing were too small to allow iodine potassium to pass through, the liquid in the tubing would not turn black.

Selective permeability refers to the ability of a membrane to allow some molecules to pass through it but no others.

In the dialysis tubing, selective permeability is used to remove some substances but not others.

The selective permeability of the dialysis tubing depends on the pore size.

When a dialysis tubing containing starch solution was dipped into a beaker containing iodine, the solution in the tubing turned black due to the ability of iodine molecules to pass through the membrane.

However, if the pores in the dialysis tubing were too small to allow iodine potassium to pass through, the liquid in the tubing would not turn black.

In this exercise we have to define what a homeostasis is and thus explain the physiological mechanisms for this concept, such as:

The homeostasis is understood as the tendency that a system has to act to maintain its own stability, even under adverse conditions and exposed to changes.

Currently, homeostasis, in general, is characterized as a condition of balance in the body's internal environment, regardless of changes in the external environment. This ensures, for example, the regulation of body temperature even in cold environments.

Changes in amino acid can be very important in the function of a protein.

The chloroplasts and mitochondria are known as the membrane bound organelles.

The cells of living organism contain membrane bound organelles which are surrounded by their lipid bilayer and they contain their own set of DNA.

Example of membrane bound organelles are:

We can conclude that, Barbie's choices are egocentric which indicates her being in the preoperational stage of Piaget's theory of cognitive development.

People who use a biopsychosocial approach are most likely to gain a: comprehensive understanding of an individual's development.

The preoperational stage is the second stage in Piaget's theory of cognitive development, which is characterized by:

The preoperational stage begins from 2 years of age up to 5 years of age. At this stage, children tend to use symbols to represent their own world.

According to Piaget, children tend to be egocentric during the preoperational stage, which explains why Chloe will get a gift like a Barbie doll for her dad. This shows Chloe, at this stage, cannot understand that her dad think in a different way she thinks.

Therefore, we can conclude that, Barbie's choices are egocentric which indicates her being in the preoperational stage of Piaget's theory of cognitive development.

In psychology, the biopsychosocial approach is a wide approach that takes into consideration biological, social, and psychological factors, and how they interact to influence health care delivery, illness and health.

Answer:

D. Has the most decomposed organic material from trees and vegetation

Explanation:

Mature soil has the most decomposed organic material from trees and vegetation. Therefore, option D is correct.

A soil that has completed all the developmental phases and becomes stable when the addition of organic material becomes equal to the withdrawal of soluble minerals by the plants.

They are formed from rocks through the process of weathering and erosion. These processes take place by the wind, water, living organisms, pressure, change in temperature, and chemical reactions. There are three layers present in the mature soil and that are topsoil, subsoil, and parent rock. These layers are known as horizon.

Thus, mature soil consists of the most decomposed material from trees and vegetation. Therefore, option D is correct.

The substance that will have more particles is 1 g of oxygen.

But

Therefore,

18 g of water = 6.02×10²³ particles

Therefore,

1 g of water = (1 × 6.02×10²³) / 18

1 g of water = 3.34×10²² particles

16 g of water = 6.02×10²³ particles

Therefore,

1 g of oxygen = (1 × 6.02×10²³) / 16

1 g of oxygen = 3.76×10²² particles

From the above, we can conclude that 1 g of oxygen contains more particles than 1 g of water

Given what we know, we can confirm that a small island far away from the mainland is the least tolerant to climate change.

A small island far away from the mainland is less tolerant of climate change from an ecological viewpoint than the other options listed. This is the case because of the size and location of the lsland. A small faraway island does not have many options for the wildlife to migrate or adapt and is therefore more intensely affected by any changes in climate.

Therefore, we can confirm that a small island far away from the mainland is the least tolerant to climate change.
