I’m pretty sure it would be C
Answer:
A. True
Explanation:
We continuously use drugs and antibiotics against the micro organisms. In the course of time, some microbes may develop resistance against these antibiotics by bringing changes or modifications in their structures. Those which become resistant, survive the selective pressure and hence selected by the nature. Hence developing drug resistance by microbes is also an example of natural selection.
Similarly herbicides and pesticides resistance developed in weeds and pests respectively after prolonged use of herbicide and pesticide is also an example of natural selection which supports the process of evolution.
Explanation:
euryhaline is the correct answer bro....
mark me brainliest
Answer:
1aNeon
b. positive charge.
c. As atomic number is equal to no. of protons and no. of electron and atomic number 10 element is Neon.
Positive charge as it have lost one of it's electron.
Atomic number = no. of protons = no. of electron and since electron can be shared loose or gain to develop charge it have loose on electron.
2a. 4 protons
b. 2 electrons
c. In question 2(a) the atomic number of Be is 4 so it would have four protons.
And as for question (b) it is said it have 2 charge which means positive charge would mean that it have lost 2 electrons and is left with 2 electrons which fulfill it's duplet configuration.
