Answers
Answer:
flexion
Explanation:
The flexion is a movement of the body part that is described the bending of an elbow, or the clenching a hand into a fist, etc. where the angle between any segment of the body and its proximal segment decreases.
In simple words, the flexion is a movement which decreases the angle between two body parts when they are moved.
The flexion occurs in the sagittal plane.
Thus, the movement of a thumb that would be mostly affected by the lesion of median nerve in cubital fossa is the flexion movement.

Answers
Answer:
This question lacks options, options are:
a) classical conditioning
b) observational learning
c) spontaneous recovery
d) operant conditioning.
The correct answer is a.
Explanation:
The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.

Answers
Answer:
basale - spinosum - granulosum - lucidum - corneum.
Explanation:
The order of strata in the epidermis:
Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.Autoclaving is the most effective among all moist heat-related antimicrobial methods. (True or False)
Answers
Answer:
True.
Explanation:
Autoclaving is the most effective among all moist heat-related antimicrobial methods because this method can kill all the harmful microbes such as bacteria, fungi and viruses. Moist heat causes destruction of microorganisms by denaturation of macromolecules that is present in their body such as proteins. Autoclaving is a very common method for moist sterilization. It is an effective method in killing fungi, bacteria, spores, and viruses but it does not eliminate prions.

Answers
Answer:
Aerobic condition.
Explanation:
When there is plenty of oxygen available in the muscles, the condition is referred as aerobic condition because the muscles do respiration in the presence of oxygen. The presence of oxygen to the muscles produced huge amount of ATP which can be used by the body in different activities as compared to anaerobic condition where there is no oxygen and the body produce less ATP for the body.

Which type of cell adhesion is useful for anchoring cells together and defending against shear forces on tissues
Answers
Answer:
Desmosomes
Explanation:
Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.

One of the ways that food can be preserved is by heavily salting it so that bacteria cannot live upon the food. What causes the bacteria to die in an extremely salty environment? Group of answer choices
Answers
Answer:
Dehydration
Explanation:
What causes bacteria to die in an extremely salty environment is dehydration due to the loss of osmotic balance in their cells.
Water molecules would normally move from the region of high water potential or low solute concentration to the region of low water potential or high solute concentration through a biologically permeable membrane.
An extremely salty environment would be hypertonic to the cells of bacteria and the cell walls of bacteria act as biologically permeable membranes. Hence, the bacteria cells lose water due to the osmotic movement of water from their cells to the surrounding salty environment.
