which guideline should you use when downloading software from the internet?

Answers

Limiting your computer's vulnerability to malware is a crucial safe browsing habit. You can protect your computer by running antivirus and antimalware software like Bitdefender, Norton, or Kaspersky. These programs can block malware from being installed and can remove it if it does get onto your computer. Even if you don't see signs of malware on your computer, running regular scans can catch any malware that has escaped notice.

Answer: General guideline or tip

Explanation:

Make sure the system requirement of the computer is good for the software to download.

The "readme file" entails the facts needed to install the software downloaded.

Make sure all other programs(software) are closed before installing. Do not forget to rebooth the computer after complete installation

To download a software from the Internet, make sure the website contains the program.

Download the software and open the folder on the computer that contains the software "download folder".

If the downloaded file is an executable file, "double click" on the icon to start installation. On the other hand, if the downloaded software file is compressed, then it must be extracted first before the set up process can begin.

Once extracted, "double click" set up to commence installation.

Bends are made in pvc conduit using a tool known as a
a. hand bender.
b. hydraulic bender.
c. heater box.
d. mechanical bender.

Answers

Answer:

C) heater box

Explanation:

The accuracy of bending is an important factor in achieving efficiency and quality in electrical installation. With this in mind, the tools are developed to achieve perfect curvature in PVC Curved Fittings according to the needs of each type of work.

In addition to the most popular PVC conduits, an even safer alternative is the HDPE (High Density Polyethylene) conduit, for ease of installation (it is lighter), strength and has a service life of at least fifty years if properly applied.

This model is suitable for more complex underground installations (such as sanitation ducts, telecommunications, urban and agricultural rainwater drainage, etc.). Within the subdivisions of the PVC conduit, the colors used for manufacturing indicate their strength potential.

Final answer:

The tool used to make bends in a PVC conduit is known as a heater box. This device applies heat to the conduit making it pliable and easy to bend. Other tools like hand, hydraulic, and mechanical bender are used for metallic conduits.

Explanation:

When you are making bends in a PVC conduit, the tool you would use is commonly known as a heater box. The purpose of the heater box is to apply a controlled amount of heat to the conduit in order to make it pliable and easy to bend. Once the conduit is heated, it can be bent to the desired angle. This process is used in the field of engineering, particularly in the areas of electrical and systems engineering where this type of conduit is commonly used to protect wiring.

The other options, a. hand bender, b. hydraulic bender, and d. mechanical bender, are also tools that are used to bend conduit, but they are generally used for metallic conduits such as steel or aluminum which require greater force to bend.

Which organelle contains chemicals that break down substances in the cell?

Lysosomes
Vesicles
Mitochondria
Nucleus

Answers

Answer:

the answer is A

Explanation:

Final answer:

The lysosome is the organelle responsible for breaking down substances in the cell using its digestive enzymes, which is crucial for waste disposal and material recycling within the cell.

Explanation:

The organelle in a cell that contains chemicals to break down substances is the lysosome. Lysosomes are specialized vesicles created by the Golgi apparatus that house digestive enzymes. These enzymes break down all types of organic polymers such as proteins, lipids, nucleic acids, and carbohydrates. This is essential for the cell to dispose of waste and to digest foreign materials like bacteria during phagocytosis. The lysosomal enzymes are highly active at low pH, which is maintained within the lysosomes, distinct from the neutral pH of the cytoplasm. Autophagy, or 'self-eating,' occurs when lysosomes break down damaged or unneeded cell components. Although often referred to as the cell's 'garbage disposal,' lysosomes play a vital role in cell health and defense mechanisms.
