Explanation:
Pathogens are disease causing organisms in the body. They attack diverse cells, organs, tissues and systems in the body thereby causing them to malfunction (to become diseased).
Antibodies are the body's natural protective mechanism against pathogens. Antibodies engulf these pathogens and digest them. Then they produce certain chemicals called antitoxins which now destroy the toxins produced by these pathogens in the body.
Also they activate the systems involved in fighting pathogens by punching the cell wall of invading pathogens.
Answer:
D) 3' TGTAGTGCGCGCGT 5'
Explanation:
DNA strand: 5' ACATCGACGCGCGCA 3'
compliment: 3' TGTAGCTG CGCGCGT 5'
DNA strands are antiparallel which means that if you're given a 3' to 5' strand, the complementary DNA strand will be 5' to 3'. If you are given a 5' to 3' strand, the complementary strand will be from 3' to 5'.
The other thing to remember for <u>DNA </u>complementary strands <u>only</u> is:
- A always pairs with T
- G always pairs with C
(for DNA only!!!!) This is one of Chargaff's principles.
If you're asked to find the RNA sequence, A pairs with U. not T! Thymine does not apply to RNA. G still pairs with C though.
As water evapo-transpires into the atmosphere from the biosphere and hydrosphere, it cools and condenses. The water droplets in the atmosphere dissolve the sulfur dioxide molecules in the atmosphere forming sulphuric acid.
The precipitation will, therefore, have a low pH because it is acidic. The runoff from the precipitation end up in rivers and ultimately in lakes.

Answer:
There are two categories of these factors: abiotic and biotic. Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
