Explanation:

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.

It is the layer that covers the most superficial part of the planet and it is where plants grow and animals live.

It supplies water, air, and nutrients to plants, provides food, energy, raw materials, and natural traits.

It intervenes in the regulation of infiltration, storage and flow of surface and subsurface water and its quality.

Filtering, pH buffering, retention of hazardous waste compounds and polluting discharges, etc.

Reserve of genes of animals and plants essential for the maintenance of biodiversity.

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.

Answer:

Leukocytes

Explanation:

Leukocytes = White blood cells that digest foreign particles

DNA helicase is the enzyme that breaks the hydrogen bonds which holds the two DNA strands together during DNA replication.

During replication of DNA , the enzyme DNA helicase separates the two strands of DNA and causes the breakdown of hydrogen bonds between the two DNA strands which leads to separating of the DNA double helix into two individual strands which make easier to copy it.

In conclusion, DNA helicase is the enzyme that breaks the hydrogen bonds.

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.

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.

Cell 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.

Environmental science is the pursuit of knowledge about the workings of the environment and our interactions with it. Environmentalism is a social movement dedicated to protecting the natural world.

Explanation:

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.

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.

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.

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!
