How might the crisis in biodiversity lead to a food crisis for humans?
EleoNora [17]

Answer:

Hi and heres your answer!

Step-by-step explanation:

The crisis of biodiversity will lead to a food crisis for humans because:

1.No varieties in certain foods like plants and animals that are healthy

2.The Less food there is,more animals go extinct which means humans will go extinct too.

and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)

Hope this helped

Tara and Curtis are simplifying [4(10)-3^2]+6(4). is either of them correct? Explain your reasoning. Why wouldnt the -3^2 be pos
Maksim231197 [3]

Simplifying the given expression, it is found that Curtis is correct.

<h3>How to simplify the expression?</h3>

The expression to be simplified is given by:

[4(10) - 3²] + 6(4)

The non-related operations can be solved first, hence:

[4(10) - 3²] + 6(4) = [40 - 9] + 24

For the square, we have to consider that:

  • For -x², the negative is not part of the square, hence the result is negative, as - x*x = -x².
  • For (-x)², the negative is part of the square, hence the result is positive, as (-x)*(-x) = x².

The first bullet point is the reason that -3² = 9. Then, the simplified expression is completed as follows:

[40 - 9] + 24 = 31 + 24 = 55.

Which means that Curtis is correct.
