Answer:
the medulla oblongata is located in region c
Explanation:
i took the test
Answer:
By phylogenetic analyses
Explanation:
The target of rapamycin (TOR) is a major regulator of growth only found in eukaryotic organisms. The TOR pathway is known to regulate critical cellular processes including, among others, cell growth. The TOR protein is a kinase capable of activating translation by phosphorylation of the ribosomal S6 kinase (S6K) and the eukaryotic translation initiation factor 4E binding protein (4E-BP). In this regard, phylogenetic studies have shown that this pathway involves duplication events of ancestral kinases, as well as sub-functionalization of the S6K kinase.
This is a result of classical conditioning in humans. Classical conditioning pairs two stimuli in eliciting a response; one stimulus is a normal stimulus (unconditioned stimulus) and another is a learned stimulus (conditioned stimulus).
In this case, humans normally salivate in response to eating; perhaps pizza from Pizza Hut from example. Food aromas and restaurant symbols do not normally elicit the response alone; but since the restaurant symbol and food aroma is paired with eating a pizza (which normally elicits the response), then the human will elicit the response in just seeing the logo of Pizza Hut and the smell of pizzas, without actually eating.
Answer:
B. 37 Degrees
Explanation:
Warm-bloodedness, also called Homoiothermy, in animals, the ability to maintain a relatively constant internal temperature (about 37° C [99° F] for mammals, about 40° C [104° F] for birds), regardless of the environmental temperature.
Answer:
The radial symmetry animals get information through their receptor cells and neurons present all over their body.
Explanation:
Radial symmetry animals can be cut in different directions. The central axis separates it into 2 equal halves and again it can be cut into 4 directions.
e.g. Hydra, sea urchin, starfish, etc
They are invertebrates have sense organs, but these sense organs are not well defined. Each symmetry of the body has sense organs. These radial symmetry organisms have oral and aboral parts.
Sea urchins, starfishes, Hydra are light sensitive. They possess photoreceptor cells in their epithelial linings. Starfishes also sensitive to touch, light, and temperature. Their spines and tube feet have motor nerves, which control their movement.
Eyespots in starfishes also help in detecting objects. It is composed of epithelial cells and responds to light. They lack a brain but have a complex nervous system. This nervous system consists of a sensory nerve and motor nerve. It spreads all over the body. Hence starfishes can react according to the stimuli.
