What are the 5 main functions of soil? List and describe each
Soil covers the surface of the Earth and is a valuable ecosystem. Soil is made up of minerals, nutrients, water, air, organic matter and microorganisms. Because of its makeup, soil has a variety of uses in a variety of industries.
Agriculture
Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.
Building
Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.
Pottery
Clay soil is used in making ceramics, or pottery. When water is added to clay soil, it can be used to create the ceramics. Once formed, you can leave it to dry and it will retain its shape. Any type of ceramic can be created with the clay soil, such as a vase, bowl, cup or sculpture.
Medicine
Soil is commonly used in antibiotics. Microbes created in the soil are harmful to bacteria, which is why soil is used in medicine. Medicines created by soil include skin ointments, tuberculosis drugs and anti-tumor drugs.
Beauty Products
Some beauty products are made with soil. Commonly used beauty products where used soil is used in the production include blush and foundation. Soil rich in clay can also be used in facial masks and toothpastes.
The main function of the soil is to serve as a seat, facilitate the permeability and circulation of water and air, being important for plant life.
What is soil?It is the layer that covers the most superficial part of the planet and it is where plants grow and animals live.
Functions of soilBiomass production.It supplies water, air, and nutrients to plants, provides food, energy, raw materials, and natural traits.
Hydrological function.It intervenes in the regulation of infiltration, storage and flow of surface and subsurface water and its quality.
Environmental function of filtering, storage and transformation.Filtering, pH buffering, retention of hazardous waste compounds and polluting discharges, etc.
Biological habitat and gene pool.Reserve of genes of animals and plants essential for the maintenance of biodiversity.
Wheater regulating function.Sink of greenhouse gases and effects on the global energy balance and the global hydrological cycle.
Therefore, we can conclude that soils acts as a filter, buffer medium and storage of water, air, nutrients and chemical products or discharges.

22. Why do you think the sea urchin was chosen to test the effect of changes in pH?
Answer:
as it settles deeper underwater ph tends to be higher and a sea urchin tends to be more resilient to change
Acidic seawater, at current pH levels found in the world's oceans, can have a negative impact on sea urchin larval development so it is taken to test the effect of changes in pH.
What is sea urchin?Sea urchins are spiny, globular echinoderms of the Echinoidea class. The urchins were able to compensate for internal pH in modest acidification (pH 7.8) and not in higher acidification (pH 7.6).
The pH of coelomic fluid was lower at higher temperatures.
Thus, due to this, the sea urchin was chosen to test the effect of changes in pH.

Which of the following statements describes a process that occurs during photosynthesis but not during cellular respiration?
ATP is produced that stores energy.
O
Chemical energy is converted to light energy.
Reactions occur in the mitochondria of the cell.
Light energy is converted to chemical energy.
Answer:
D (see below for explanation)
Explanation:
Using the process of elimination, we can go down the answer choices:
A) ATP is produced that stores energy.
In photosynthesis, light energy, water, and carbon dioxide is taken in and converted to oxygen and glucose. Cellular respiration, however, uses glucose and oxygen and converts it to water, carbon dioxide, and ATP.
As you can see, there is no mention of ATP in photosynthesis. ATP is not created in photosynthesis—photosynthesis' main purpose is to make food for the organism.
So A is not the answer.
B) Chemical energy is converted to light energy.
In photosynthesis, the light energy taken in is converted to chemical energy so it can be used. Cellular respiration requires only oxygen and glucose, so light energy doesn't relate to cellular respiration directly.
However, if you read the answer carefully, it says that chemical energy is converted to light energy. The main purpose is to use the light energy, which cannot be used in its light form, so it has be converted into chemical energy.
So B is not the answer.
C) Reactions occur in the mitochondria of the cell.
Photosynthesis occurs in the chloroplasts of an organisms. Heterotrophs do not have chloroplasts, so they cannot make their own food. However, mitochondria are in all eukaryotic cells, as cellular respiration occurs in all eukaryotic cells as well.
Cellular respiration happens in the mitochondria of a cell. Photosynthesis does not.
So C is not the answer.
D) Light energy is converted to chemical energy.
If you go back to my explanation for B, you can see that photosynthesis uses light energy, but to do so, it has to convert it to light energy first. It cannot use light energy itself.
So D is the right answer.

Can you describe a frogs metamorphosis, including whether it is complete or incomplete
Explanation:
Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.
During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear. When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!

describe the different processes involved in the movement of these substances into and out of the cell; oxygen, carbon dioxide, glucose, potassium, water, and enzymes.
Answer:
Dissolved or gaseous substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen. Diffusion occurs when particles spread.
Explanation:
To enter or exit a cell, dissolved or gaseous substances must pass through the cell membrane. One of the mechanisms that makes this possible is diffusion. Particles diffuse when they spread.
What is cell?Cell is defined as the fundamental membrane-bound entity that houses the essential molecules of life and is the building block of all living things.
It can also be defined as a semipermeable cell membrane encloses one or more nuclei, cytoplasm, and different organelles, which are the smallest structural component of an organism capable of autonomous functioning.
There are basically two types of cell.
Prokaryotic cellEukaryotic cellCell membrane is defined as a biological membrane that keeps all cells' interiors isolated from the outer world and provides protection for it.\
Barriers and gatekeepers are cell membranes. Because of their semi-permeability, some molecules can diffuse across the lipid bilayer but not others.
Thus, to enter or exit a cell, dissolved or gaseous substances must pass through the cell membrane. One of the mechanisms that makes this possible is diffusion. Particles diffuse when they spread.

Your skin cells have 46 chromosomes. After they complete the cell cycle, how many chromosomes will be in the daughter cells? Explain.
Answer:
46
Explanation:
The skin cells with 46 chromosomes will each produce daughter cells with 46 chromosomes after they complete the cell cycle.
The skin cell is a vegetative cell that can only divide through mitosis. Mitosis is also referred to as equational division during which a cell produces two daughter cells that are both genetically and phenotypically similar to the parent cell.
During the cell division, at the anaphase stage to be precise, the chromosomes are separated into sister chromatids and sister chromatids of the same chromosomes move in the opposite direction to the poles of the cell before the cytoplasm of the mother cell divides to produce two independent daughter cells. Each chromatid in the new daughter cells then goes ahead to become a complete chromosome with two sister chromatids.
Hence, at the end of the cycle, each daughter cell ends up having the same 46 chromosomes as the parent cells.
