wrist drop results in an inability to extend the hand at the wrist. which nerve would most likely be affected in this injury

Korvikt [17]

Explanation:

Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.

Factors derived from factor analysis may themselves be interrelated. When such factors are themselves factor analyzed, the resul

Resulting factors are called Second-order factors

<h3>What is factor analysis?</h3>

Factor analysis is a statistical approach for describing variability in seen, correlated variables in terms of a possibly smaller number of unobserved variables known as factors.
It is possible, for example, that fluctuations in six known variables mostly reflect variations in two unseen (underlying) variables.
Factor analysis looks for such joint fluctuations in response to latent variables that are not noticed.
Factor analysis may be regarded of as a specific form of errors-in-variables models since the observed variables are described as linear combinations of the possible factors plus "error" terms.
It may help to deal with data sets where there are large numbers of observed variables that are thought to reflect a smaller number of underlying/latent variables.
It is one of the most commonly used inter-dependency techniques and is used when the relevant set of variables shows a systematic inter-dependence and the objective is to find out the latent factors that create a commonality.

How does the shape of an enzyme affect the reaction

elena55 [62]

Answer:

The shape of the enzyme determines which chemical reaction it will speed up.May strain the bonds of the substrate or put chemical groups of the active site in the correct position to speed up the reaction.

Describe the process of skeletal muscle contraction by assembling the following 10 events in the proper order in paragraph form.

balu736 [363]

5) muscle fiber is stimulated at the neuromuscular junction triggering an action potential

7) APs travel down the T-tubules to the sarcoplasmic reticulum

Released acetylcholine (due to action potential within motor neuron) from the motor neuron initiates depolarisation within the sarcolemma, which is spread through the muscle fibre via T tubules.

8) in response to an AP, calcium ions are released into the cytosol/space around the myofibrils

Depolarisation causes the sarcoplasmic reticulum to release calcium ions necessary for the contraction

3) calcium ions bind to the T and T system

1) T and T system undergoes a conformational change, exposing the myosin binding sites on actin

6) myosin head/cross-bridges bind to actin

The binding sites for the myosin heads located on actin, are covered by a blocking complex (troponin and tropomyosin) that can be unblocked by the calcium binding

2) myosin heads/cross bridges bind to actin and flex, shortening the sacromere

4) actin filaments are pulled toward the center of the sacromere, shortening the muscle fiber

As the individual sarcomeres become shorten the muscle fibres as a whole contracts

10) myosin head continues to attach, flex, release, extend, and reattach as long as calcium ions are present

9) calcium ions actively transported into the sarcoplasmic reticulum

Relaxation of a muscle fiber occurs when a Ca ions are pumped back into the sarcoplasmic reticulum .
