Why does mature soil contain the why does mature contain most humus?
a. Has the least decomposed organic material from trees and vegetation
B The mature soil has the most soil horizons
C The mature soil has the biggest layer of bedrock
D. Has the most decomposed organic material from trees and vegetation
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.
What is matured soil?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.

. Define homeostasis and describe how this concept can be used to explain physiological control mechanisms
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.
What is the definition of homeostasis?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.
What are the main factors that regulate homeostasis?Temperature;Salinity;pH;Concentrations of nutrients such as glucose, gases such as oxygen and waste products such as carbon dioxide and urea.See more about homeostasis at brainly.com/question/9087319

Which of following has the least ecological tolerance to climate change?
- Small island close to the mainland
- Small island far away from the mainland
- Large island close to the mainland
- Large island far away from the mainland
Given what we know, we can confirm that a small island far away from the mainland is the least tolerant to climate change.
Why is this the case?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.

If you had a gram of water and a gram of oxygen, which substance would you have more particles of? Why?
The substance that will have more particles is 1 g of oxygen.
Avogadro's hypothesis 1 mole of water = 6.02×10²³ particles 1 mole of oxygen = 6.02×10²³ particlesBut
1 mole of water = 18 g1 mole of oxygen = 16 gTherefore,
18 g of water = 6.02×10²³ particles 16 g of oxygen = 6.02×10²³ particlesHow to determine the particles in 1 g of water18 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
How to determine the particles in 1 g of oxygen
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
SUMMARY 1 g of water = 3.34×10²² particles 1 g of oxygen = 3.76×10²² particlesFrom the above, we can conclude that 1 g of oxygen contains more particles than 1 g of water

What are marine algal blooms, red tides, and dead zones? How might biological magnification play be part in human illness?
Answer:
Cyanobacteria, a type of photosynthetic bacteria also known as blue-green algae, are often the cause of algal blooms in freshwater and occasionally in marine water. ... Cyanobacteria HABs produce multiple toxins, including liver, nerve, and skin toxins, which can affect human and animal health.
Many red tides produce toxic chemicals that can affect both marine organisms and humans. The Florida red tide organism, K. brevis, produces brevetoxins that can affect the central nervous system of fish and other vertebrates, causing these animals to die.

comprehensive understanding of an individual's development.
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.
What is the Preoperational Stage?
The preoperational stage is the second stage in Piaget's theory of cognitive development, which is characterized by:
EgocentrismSymbolic representationThe 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.
What is the Biopsychosocial Approach?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.
Therefore, people who use a biopsychosocial approach are most likely to gain a: comprehensive understanding of an individual's development.
