In a small cramped kitchen, you and some friends are preparing a spaghetti dinner. the water is boiling and the pasta is now ready to be carried to the sink to drain. you pick up the pot of bubbling pasta water and start in the direction of the sink. the pot holder slips slightly, causing the water to splash onto your arm. the scalding water burns your forearm. you are experiencing a lot of pain, with a red, blistering burn on your arm.
The appropriate first response will be to cool the affected arm under running water and application of ice pack. The cold temperatures will lower the pain that is being felt.
A dominant trait can be shown both when an organism is homozygous dominant AND heterozygous. Two different genotypes give the same visible result so a testcross is needed to be able to accurately say if the organism is homozygous dominant or heterozygous
Answer:
paracrine signaling.
Explanation:
Chemical signaling between cells is one of the most important ways that activities of tissues and organs are coordinated. The nervous system is the other major coordinating system in animals, but even here chemical signaling is used between adjacent neurons. The mechanisms involved are described as either being paracrine, autocrine, intracrine, endocrine, neuroendocrine or pheromones. Paracrine signals diffuse locally and act on neighboring cells.
