Answer:
-4,0
Step-by-step explanation:
hi have a nice day,❤️
Occurrence of diversity in ecosystem sustains particular characteristic of a biological community and also ensures stability of the community. Transgenic crops may affect insect biodiversity by unintended impacts on non-target arthropod population. For example, transgenic GM cotton specific to target lepidopterous pests can change the cotton pest spectrum and may induce the growth of new harmful pest species having no pest status. The change in species composition may influence IPM approach in cotton crop. The results of authors’ research studies as well as global impact indicate that GM cotton is highly specific to target pests and has no unintended impact on non-target insect population. GM cotton provides significant season-long field control of target pests (Helicoverpa armigera, Earias spp. and Pectinophora gossypiella), with no significant control of Spodoptera species. The decreased insecticide use in GM cotton has a positive impact on beneficial insect populations and can increase the stability of rare species.
let the unknown answer be equal to f
.-2.1 - f = -3/2
-f = -3/2 + 2.1
-f = 0.6
f = -0.6
Camp Summer Fun will need about 83 tents.
The actual number of tents needed is less than the estimate because 331 divided by 4 is 82.75 and because I rounded to 83 it is less.
Hope this helped :)
Answer:
Simplify.
(2x2 - 5x + 3) - (-x2 + 4x - 5)
the answer is -7x +12
Step-by-step explanation:
the question can be solved using BODMAS law
from Simplify.
(2x2 - 5x + 3) - (-x2 + 4x - 5)
opening the bracket
4-5x + 3 + 2x - 4x + 5
collecting the like terms we have;
12-7x
therfore ; -7x + 12
