Rus_ich [418]

Answer: teleconferencing

Explanation:

    Using peer-to-peer collaboration will not work if the members work at many different locations.

    While instant messaging may work, it can be hard to have a meeting this way.

     Templates do not apply to this situation.

     This leaves us with the answer of "teleconferencing" as you can have a meeting with people online, even when they are far apart.

Which features do most stratovolcanoes and cinder cone volcanoes have in common?
Sergeu [11.5K]

Answer:

Option (2)

Explanation:

Strato-volcanoes are the steep, conical shaped, formed by the alternative beds of ash and lava. The magma in this type of volcano contains high silica content and are comprised of bubbles. When the gases are released from these bubbles, then a greater force is exerted from the bottom towards the surface. Due to this, they are very explosive and ejects a huge amount of materials during eruption. For example, Mount St. Helens .

Cinder cones are the simplest volcanoes with steep sides. They are made of the materials and semi solidified lava that are ejected from the vents of the volcano. Eruptions are often explosive due to the force exerted by the gas and the molten lava and are accumulated near the vent. For example, Paricutin.

<u>These two types of volcanoes are similar in terms of its eruption that is violent and explosive in nature. In addition to that, they both have steep sides. </u>

Hence, the correct answer is option (2).

A virus
irga5000 [103]

Answer:

The correct option is C. A virus contains RNA or DNA in a protein coat.

Explanation:

Viruses can be described as tiny particles which are able to incorporate their genetic material into a host. Many viruses can be destructive to the host cells.

The structure of a virus includes DNA or RNA which is enclosed in a structure known as an envelope or capsid. The envelope or capsid is made up of proteins. Some viruses also have a tail.

The capsid of a virus usually remains outside the host cell and it injects its viral genome into the host cell. The DNA or RNA o the virus then incorporates in the host cell.
