B. The tick is a vector. Vectors are like vehicles that carry genetic material. The tick is carrying the genetic material of lyme disease to the animal.
<span>The mitochondria in eukaryotic cells originated from prokaryotic cells, bacteria that were once free-living. The mitochondria have their own DNA, which is inherited from the mother in most species. Similarly, plant cells have organelles called plastids which contain their own DNA and originated from free-living bacteria. The chloroplasts in plant cells, which convert the energy of sunlight into chemical energy via photosynthesis, are a kind of plastid, and they originated from bacteria that could do photosynthesis.</span>
Answer:
B. Generalizable
Explanation:
Generalizable means something's ability to be applied to a general or wide group. So, if something is generalizable that means that it is applicable to a wide group of things outside of the initial study. Thus, B is the correct answer because it is the only vocab word that properly describes how widely applicable the study is.
One of the best ways to generalize a study is to use random or probability sampling. This helps ensure that the findings of the study can be used by others in different situations.
Answer:
Thoracolumbar origin, short preganglionic fiber, ACh release at ganglion, long postganglionic fiber, NE release at effector
Answer:
Option). NK cells.
Explanation:
Cluster of differentiation 8 (CD8) can bed defined as a transmembrane glycoprotein that acts a co-receptor for the receptor present on T cells (TCR). The CD8 is marker for 
cells (cytotoxic T cells) as it is predominantly present on cell surface of these cells.
Along with cytotoxic cells, CD8 molecule is also expressed in surface of natural killer cells (NK cells), thymocytes, and myeloid dendritic cells.
Hence, a cell having CD8 on its surface (cytotoxic T cell) would be most similar to NK cells.
