2. Sporophyte

Explanation:

The life cycle of the Liverwort and mosses which are placed in the Bryophytes is divided into the sporophytic and the gametophytic phase.

Gametophyte

The gametophyte is the dominant phase of the life cycle which appears like the ribbon, green in color and posses the gamete producing structure- the antheridium and the archegonium.  

Sporophyte

The gametes fuse to form the embryo and from that is produced the sporophyte structure, an umbrella-like structure called a sporangium. This sporangium produces the spores which later will form the gametophyte.

alexdok [17]

Answer:

Explain how natural resources are identified:

Satellites are machines that are launched into space. They move around the Earth to get information that can help identify natural resources. How do satellites do this? Satellites scan the Earth’s surface to get information about its color and brightness. This information is used by a computer to make a “computer map”. Once they finish the "computer map" a person would look at the map and determine which materials are which. These maps are not for showing a person how to get from one place to another, but for showing what the surface of Earth looks like and what it is made of.

Why are natural resources unevenly distributed:

The formation of these resources requires certain conditions. For example, copper ores are formed where there is volcanic activity. Iron ores were formed a long time ago when certain substances combined to form sedimentary and other types of rocks. So, iron ores could be found more often in places with environments that were just right for the formation of these rocks. Graphite forms when another type of rock, called metamorphic rock, is formed.

Explanation:

This is what I put and I got all the information from the text on edge 2021.

nordsb [41]
The answer to this question would be endocytosis.

Endocytosis a process to bring outside material into cell. The word "endo" itself mean "inside". This material could be source of energy or microbes that need to be killed. It's opposite would be exocytosis. The word "exo" itself mean "outside".
Both of them is pretty similar because they use vesicle to transport the things that need to be moved.

Vilka [71]
This is from another brainly answer it's the same questions but it should be the correct answer because it's a certified answer. Hope this helps!

Tuber is thick underground stem, such as potato for example. It usually has buds from which new plants could grow. So, the first part of Stacy's vegetable is definitely turbous stem. The other part must be root, because it has hairy structures. These hair-like structures have function in <span>the absorption of water and minerals from the soil.</span>
