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 of the following describes how the winter season affects organisms in the tundra biome?
alukav5142 [94]

The correct answer is D. Animals not adapted to cold migrate to warmer regions, because suppose that the cold temperatures kill most of the plants, so if they can die why they select that place to live? The option B is not logical because this require long time to evolve this characteristic and the option C has more logic but it still not enough, because if the temperatures are colder more animals can die. I hope this help.

Stells [14]

Answer:

The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. It can be transferred by things that feed from what has pollen. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
