Answer:
If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion. If it loses an electron, it becomes positively charged and is known as a cation.
Explanation:
Answer:
adaptive; innate
Explanation:
The adaptive immune system refers to a specific type of immunity which is found only in vertebrates. Adaptive immunity is defined by the presence of specialized immune cells (i.e., lymphocytes such as T and B cells). The B cells produce molecules known as antibodies which destroy specific pathogenic microorganisms (e.g., bacteria, viruses) and thus prevent diseases in the future. On the other hand, the innate immune system is the first (and evolutionary more ancient) defense line against pathogenic infections or tissue injury. Innate immunity includes, among others, physical barriers, anatomical barriers, phagocytic enzymes (i.e., lysozymes), phagocytic cells (i.e., macrophages), inflammation, etc. Inflammation is defined as an innate immune response composed of complex biological processes that protect the body by eliminating harmful microorganisms and intracellular danger signals, thereby regulating signaling pathways of many diseases.
Gymnos were the first plants to inhabit the Earth, while Angios came later. The Angios rely on animals to pollinate them, by eating their fruit and then exposing the seed to grow in soil wherever they take it. Gymno means "naked seed" so these cone structures fall by wind gusts and grow where they land if fertile soil be present where they fall. Therefore the correct answer is:
C. Gymnosperms are mostly adapted for wind pollination; angiosperms are mostly adapted for animal pollination.
