Well, the thing is: we don't really know, as we don't even know how many species there are on earth.
If we take a look at the estimates of <span>World Wide Fund for Nature, an organization that works toward combating species extinction, their estimates vary from 200 to 100 000 - but a probable number is 20 000 (d). </span>

Answer:
a b c and d are all valid answers.
Explanation:
According to my research on the consumer purchasing process, I can say that based on the information provided within the question all of the answers provided are factors. This is because, if you ever talk to professional who has studied individuals buying products they would say that all aspects come into play when the individual makes a purchase. Such as whether other people are using that produce (social), how they are going to feel about that product (psychological), and if they can afford that product (situational), yet all of these aspects would not happen if the individual was not aware of the product through the firm's marketing mix.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Let the data is as following
mass of payload = "m"
mass of Moon = "M"
now we know that we place the payload from the position on the surface of moon to the position of 5r from the surface
So in this case we can say that change in the gravitational potential energy is equal to the work done to move the mass from one position to other
so it is given by
we know that
now from above formula
so above is the work done to move the mass from surface to given altitude
