Explain how ships transport invasive species in the ballast?

Answers

Answer 1

Answer:

Larger ships transport invasive species in their ballast water, while fouling organisms such as barnacles, seaweeds and mussels can move from one location to another by hitching, a ride on a boat, on items you use in the water and even your clothes

What are the 5 main functions of soil? List and describe each

Answers

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 soil

Biomass 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.

Answers

Answer:

The “recommended temperature limit” represents limit of the temperature that is good for our world.

Explanation:

The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the emission of carbondioxide gas in the atmosphere increases due to this increase temperature..

specialized gas-exchange system.?
fi)explain why the method of gas exchange in (a)i above is only possible in very small organisms.?​

Answers

Answer:

In single celled organisms surface area to volume ratio is optimum for diffusion/exchange of substances between the cell and its exterior and this rate of exchange suffices the requirement of a unicellular organism. However, in multicellular organisms the surface area to volume ratio is low,  the exchange that takes place with the exterior or the environment occurs only through the body surface with the help of a specific structure/organ, example (Skin),However, this exchange does not compensate for millions of cells in a multicellular organism, which have distinct requirements based on their function

Explanation:

i) Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion.

ii)The oxygen gas diffused inside the body is used up by amoeba. carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion.

Use your knowledge of osmosis to explain why the mass of each cube increased.

Answers

Osmosis passes from a medium with a high concentration of water molecules to another with a low concentration of water molecules and since the potato has low water concentration so the water transfers to it increasing its mass

The mass of each potato cube increased because they have gained water by osmosis.

Recall that: osmosis is the movement of water molecules from the region of high water concentration (high water potential) to the region of low water concentration (low water potential) through a semipermeable membrane.

A solution with a high solute concentration will have low water potential and vice versa. They are also said to be hypertonic when compared to a solution with a low solute concentration (hypotonic).

Thus, the potato cubes increased in size because the cells of the potato have low water potential when compared to the distilled water in which they were thrown. In other words, the cell sap of the potato cubes is hypertonic while the distilled water is hypotonic.

Pepsin is an enzyme produced in the stomach. Pepsin has an optimum pH that is very acidic, between a pH of 1.0 and 2.0. In an
experiment involving the enzyme pepsin, the pH is raised from 2 to 11. What will be the MOST LIKELY effect of this on the reaction?

Answers

Explanation:

the pepsin enzyme will not be able to work in a basic medium when ph raised from 2 to 11 it's efficiency will be affected and will not be in a condition of digesting protein .

plz mark my answer as brainlist plzzzz.

hope this will be helpful to you .

When the pH is raised from 2 to 11 the most likely effect on the reaction is ;  

The rate of reaction will decrease/delayed

Given that Pepsin enzyme has an optimum pH of 1.0 to 2.0, it will perform efficiently as a catalyst in an experiment whose pH levels fall within the range of the optimum pH of Pepsin.

Pepsin enzyme accelerates the digestion of proteins therefore when the pH levels are raised above 2.0 the efficiency of Pepsin enzyme will be negatively affected and the digestion of protein will require a higher activation energy.

Hence we can conclude that When the pH is raised from 2 to 11 the most likely effect on the reaction is The rate of reaction will decrease/delayed.

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
