An item that is free of all viable microbes including endospores is considered to be a <u>sterile item</u>.
Such a substance or equipment that is free from all kinds of microbes, spores, or any other infectious agent is referred to as a sterile item. There are various sterilization techniques and procedures that are used in order to make a sterile item.
in labs, where researches have to be made, all items need to be sterile as an invasion of any other microorganism can make a research study go wrong.
Some of the common means through which sterilization is achieved are using heat, chemicals, irradiation, etc.
After an item has undergone a proper sterilization method, it is referred to as a sterile item that can now be used.

The answer is <span>A. Dermal tissue, ground tissue, and vascular tissue respectively.
<em>
</em>1. <em>Epidermis is dermal tissue. </em>Dermal tissue covers the plant from the outside. It consists of epidermis and periderm. Epidermis is a single layer that covers young plants.
2. <em>Sclerenchyma is ground tissue.</em> Ground tissue has a variety of functions. It consists of sclerenchyma and parenchyma. The function of sclerenchima is support and strength of roots, stems, and leaves.
3. <em>Phloem is vascular tissue.</em> Vascular tissue has a role in transport of minerals, water, and organic compounds. It consists of phloem and xylem. Phloem transport organic compounds, such as carbohydrates, hormones, etc.

Answer:
1- Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.
2- Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.
3- Humans affect erosion rates in a number of ways across the globe. ... Human activities such as repeatedly walking or biking the same trails or areas can also contribute to erosion slowly over time. Forest fires also contribute to soil erosion, as vegetation previously holding the soil in place is often destroyed
4 - The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
5 - You can reduce soil erosion by:
Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens. ...
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
