vines and trees are both plants but, they are very different from each other. what adaptations can you see in these plants, and how do you think these adaptations help them survive

trees have well-developed roots and leaves.
vines can crawl in walls and other trees that catches better sunlight and rainwater. 

Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time.

What are levels of organization in multicellular organisms?

Answers

The cellular organization relates with one another since the colossal cell, the organ system is fundamentally composed of cells. Cells are the building blocks of these structures and which creates such organ and organ system. They associate as one cell intercommunicates with another cell until all received the message and translates it and sends it with another organ and to cell -vice-versa. And also, they become interdependent with the other cell -other tissue -other organs -other organ system. 
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole. Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis.This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. How? Through cell division called, mitosis. Excerptmeiosis –cell division specifically in the sex cells.

Answers

The Homo ergaster occupy  Africa ​1.6 million years ago. Therefore, option A is correct.

Who are Homo ergasters and where did they live?

The oldest early humans known to have had proportions similar to modern humans, with relatively long legs and shorter arms compared to the size of the torso, are the early African Homo erectus fossils (also known as Homo ergaster).

At the onset of the lower Pleistocene and the lowering of the environment, Homo ergaster, sometimes known as the "working man," is an extinct species of hominid (or subspecies, according to some authorities) that existed throughout eastern and southern Africa between 1.9 and 1.4 million years ago.

Thus, the Homo ergaster occupy Africa ​1.6 million years ago. Therefore, option A is correct.
