Answer:
In this case, the scientist want to test the presence of the limonite in the yellow rocks, So, proposed hypothesis should include the color of rock they want to observe and the posssible outcome, which need to be tested. So, a proposed hypothesis can be: The rocks, which have yellow color are made up of mineral lime.
Answer:
The correct answer is - Basophils
Explanation:
Basophils are one of the granulocytes of WBC. The basophils move to site of damaged tissue. They cross the capillary endothelium and gathred in the damaged tissues. They discharge their granules into the interstitial fluids.
The granules which is secreted by basophils includes histamine, heparin, and serotonin.The histamine dilates blood vessels, the heparin prevents blood clotting.
These chemicals into the interstitial fluids enhances the inflammation initiated by mast cells.
Answer:
antibodies being produced to fight off a pathogen inside the body
Explanation:
Specific immune responses, also known as the adaptive immune system are ways the body fights against pathogens. The body is able to identify cells that are unique to it. When pathogens bearing an unknown identity enter the body, antibodies are released to attack the antigens on the surface of these pathogens.
The body usually develops this immunity after a previous attack by the pathogen. Lymphocytes known as the B and T cells are released by the immune system t engulf the pathogens.
A recessive trait inheritance could be more prevalent in a population than the dominant because mutation could occur because the mating does not have a wide variation causing a lethal gene or an autosomal sex link to be easily passed on the offspring
When we discuss superposition in biology term then its principle tells that one by one rocks or sediments settles.The superposition mean that the older rocks or sediments place below all newly coming sediments or rocks place on first layer so layer over layer formation is called superposition.
