Video transcript

Hello everyone. And in today's video we have a very short problem. So let's jump straight into it. So which of the following best describes the tundra. So, recall from previous videos that tundra is a biodome. And these biofilms are areas that contain certain factors such as temperature, rainfall and more, that just create specific environments for straight in organisms to live in it. So they are very unique in that sense. Now that we know this, let's talk about some or use a very important characteristic that tundra at this place and it is that tundra is a very frigid and called by OEM because of this. The plant species that live here are short and they're grouped together to resist this snowfall that happens in tundra. So now that we know this, this took over answer choices so we can solve the question beginning by answer choice A Its vegetation is composed of dwarf shrubs, sedges, grasses and moses. So again, if you look at dwarf shrubs, these are very short and all of these types of vegetation are short, grouped up together. So this actually correlates with our definition and it's a correct answer story. So we're not going to cancel it out. And moving on, we have B it has a frigid temperature. Now, here we saw that two brothers knows a lot. There is very cold. It has a frigid temperature. So it is also correct as well, since these two answer choices are correct. If we look at answer choice D there's more than one correct answer that is actually going to be the answer choice because we have two or more correct answer choices, so that is going to be the final answer to our question. And I really hope this video helped.
