Answer:
Another specialization of the skeletal muscle is the site where a motor neuron's terminal meets the muscle fiber—called the neuromuscular junction (NMJ). This is where the muscle fiber first responds to signaling by the motor neuron.
D. Neuromuscular Junction
Answer:
results could be biased and therefore they are not reliable
Explanation:
A conflict of interest is generated when the authors of a given study have any type of interest that could influence their judgments, results and/or conclusions. These conflicts of interest include any relevant financial relationships, personal, religious, political or intellectual interests. To solve this situation, peer-reviewed, well-reputed journals generally include a conflict of interest statement where authors declare all interests that might be perceived as conflicting.
The spines of the cactus have several functions, which are the following:
To defend them from possible predators: inside the body of the plants there is a great deal of water; if herbivores could access it, these plants would not survive.
To provide them with shade: it is true that not much, but it is enough so that the loss of water by evaporation is minimal.
Reflect sunlight: many species have white spines.
Answer:
- light positioning: c. Extrinsic muscles; d. Pupil
- sensory processing: a. Photoreceptors; b. Occipital cortex; e. Bipolar cells
Explanation:
Extrinsic (extraocular) muscles are muscles that modulate both eye movement and position, whereas intrinsic (intraocular) muscles are muscles that focus the eye and control how much light enters into the eye. The pupil is the black center of the eye within the iris through which light passes before being focused onto the retina. Photoreceptors are specialized neurons located in the retina that respond to light, converting it into electrical signals that can stimulate biological processes. Photoreceptors in the retina are divided into two categories 1-rods (responsible for vision at low light levels), and 2-cones (active at higher light). Bipolar cells are neurons that transmit signals from the photoreceptors to the ganglion cells, thereby processing light signals received from rods and cones. The occipital cortex is a brain region that represents the visual processing center and contains most of the anatomical region of the visual cortex.
Answer:
false
Explanation:
"Electrons are the "material" of the charge that is flowing. Therefore, current can never cause a metal object to become positively or negatively charged, because the net number of electrons in the metal object will never change due to current flow."
