<h3>True.</h3><h3>Explanation:</h3>

The main source of water is in the ground and the groundwater gets constantly more polluted with road salt, oil, gas and other chemicals (and as you can see, these are all manmade products).Sewage, trash and liquid waste of households, agricultural lands and factories are released into lakes and rivers.

Answer:it is a similar thing to natural selection, the ones less effected by it survive and adapt over time to survive the vaccine. However, google defines it this way, "The adaptive immune system, also known as the acquired immune system or, more rarely, as the specific immune system, is a subsystem of the overall immune system that is composed of highly specialized, systemic cells and processes that eliminate pathogens or prevent their growth"

REY [17]
The answer would be D. Shrubs, fungi, insects, and bacteria. Shrubs and fungi are definitely main decomposers and insects and bacteria do consume dead matter and waste so they also count as decomposers.

irinina [24]
Simple problem my friend!

First we must replace X with -2,-1,0,1,2
then we plug in -2 in X. 8*-2 is -16 and adding 12 gives us a co ordinate of (-2,-4) now this is not enough so now we must do -1. 8*-1 is -8, + 12 gives us 4. so now our second co ordinate is (-1,4). i will do 1 more co ordinate and then you should be able to finish the problem by yourself :) we now plug in 0 to replace X. 8*0 is 0, easy and 0+12 is 12. so the third co ordinate is (0,12) when you have put all the dots on the graph be sure to draw a line through them and by the way, this is not a biology question lol, good luck!

Novosadov [1.4K]

Answer:

D. A population with high genetic biodiversity is better able to respond to environmental stressors.

Explanation:

The genetic biodiversity of a species is the diversity of alleles that it possesses in its genetic pool. For a given gene, a population can have one or more alleles; and the more alleles the population has, it will be more diverse. Under normal conditions (without stress), the alleles that are present in high frequency in a population,  are those that best respond to the environment where the population occurs. However, if some environmental condition changes and some type of environmental stress emerge (ie drought), it is possible that these alleles no longer respond equally effectively and then, it is possible that the  alleles that on normal conditions occur with low frequency, are more adequate to face the stress. A population with fewer alleles (less genetic diversity) has terefore fewer options to deal with environmental stressors and<u> a population with high genetic biodiversity</u> will do this better.
