Answer:
The cilia is one of the things that act defensively in the respiratory system.
Explanation:
It propels a mucus-like liquid that covers the airway which traps pathogens (potentially infectious microorganisms) and other particles, preventing them from reaching the lungs.
Answer:
There is no attachment to this question, however, the base sequence on the model built by the student is: CAGCCATC
The options of the bases on the complementary model are:
A) CTACCGAC
B) GUCGGUAG
C) GTCGGAAG
D) GTCGGTAG
The answer is D
Explanation:
A DNA molecule is a polymer biomolecule made up of nucleotide bases. It is a double stranded molecule, with each strand containing nucleotides held together by hydrogen bonds. The pairing of nucleotides in one strand of DNA to another follows the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine binds to Thymine (A-T) while Guanine binds to Cytosine (G-C).
According to this question, a student builds a model containing the base sequence: CAGCCATC, the model that contains bases that are complementary to the ones built by the student is: GTCGGTAG
There are two types of toxins; endotoxins and exotoxins. ... On the other hand, endotoxins are less lethal but can cause fever to the host. Exotoxins are secreted by bacteria and release outside the cell whereas endotoxins are bacterial toxins located within the cells.
It’s a simple thing really, the more options or “diversity” it’s more likely that it will be more sustainable and things will find a way to survive. Think about it like a video game level, the more tries you have the more likely you are for success
