Through my research I found matching questions with similar answers:
A) macrophages
B) antigens
C) antibodies
D) lymph
The best answer to fill in the blank would be the third option C) Antibodies which in the name anti means against, so since the word anti is the same as against, its a battle between antibodies and invaders, so that's why its C).
Cytosine pairs with Guanine
Adenine and Thymine are pairs also
Hope this helps :)
Answer:
Erythrocytes is the answer
The survival of the 2 percent of the population is due to the presence of a gene obtained from other species. This gene must be responsible for developing resistance in the insects, against the insecticide that was used by the farmer. The gene got incorporated in only 2% of the insects and therefore, they survived and rest of them were susceptible to the insecticide and thus, died.
The answer is Urine specific gravity less than 1.025. Because
the exact gravity is less than 1.025 after treatment, the outcome is measured
positive. In syndrome of unsuitable antidiuretic hormone (SIADH), the specific
gravity is greater than 1.025. Small cell lung cancer is a risk factor of SIADH.
