Answer:
Social media changes daily, social media changes depending on the audience. People used to see social media as more of a negative place where hate would be spread. but over the years it has become increasingly positive.
The answer is superb the reason why is because abysmal means something bad while superb means the opposite of that, which is good. Hope this helps!
Subdividing [0, 1] into 10 equally spaced intervals of length 
gives the partition
![[0,1] = \left[0,\dfrac1{10}\right] \cup \left[\dfrac1{10},\dfrac2{10}\right] \cup \cdots \cup \left[\dfrac9{10},1\right]](https://tex.z-dn.net/?f=%5B0%2C1%5D%20%3D%20%5Cleft%5B0%2C%5Cdfrac1%7B10%7D%5Cright%5D%20%5Ccup%20%5Cleft%5B%5Cdfrac1%7B10%7D%2C%5Cdfrac2%7B10%7D%5Cright%5D%20%5Ccup%20%5Ccdots%20%5Ccup%20%5Cleft%5B%5Cdfrac9%7B10%7D%2C1%5Cright%5D)
The 
-th subinterval has left and right endpoints, respectively, given by
where 
.
The midpoint of the -th interval is the average of these,
We approximate the area under 
over [0, 1] by the Riemann sum,
(D)
convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. Indeed, apart from random mutations, each successive duplicate cell will have the same genetic composition as its parent, due to the inheritance of the same chromosome set and similar biological environment. This works well for replacing damaged tissue or for growth and expansion from an embryonic state.
Because the genes contained in the duplicate chromosomes are transferred to each successive cellular generation, all mitotic progeny are genetically similar. However, there are exceptions. For example, there are genetic variations that arise in clonal species, such as bacteria, due to spontaneous mutations during mitotic division.
