As Abe continued his fitness regimen, he started to think more about his muscle anatomy. He wondered how he was able to adjust the force generated by his muscles when he lifted different weights. His anatomy instructor explained motor units to him. Which of the following best explains how motor units are involved in controlling force exerted by muscle?
A. A single motor neuron innervates a specific set of muscle tibers within each muscle. When more force is needed, more motor units are activated, which states mere matice fbers to contract
B. A motor unit in composed of all the muscle fibers within a singie tascich Addition fascicles will be activated when more force is needed
C. Each skeletal muscle fer is innervated by a single motor neuron, so there are as many motor neurons as fibers within a single musch When more force is needed addition motor neurons will be activated, and their individual fibers will contract
D. Each muscle has one motor neuron that can selectively activate as many foers as are needed when trying to in heaver objects a single motor neuror will just some more Ebers to contract Submit Putn Muscle shorteninn

Answers

Answer 1

Answer:

d). A single motor neuron innervates a specific set of muscle fibers within each muscle. When more force is needed, more motor units are activated, which stimulates more muscle fibers to contract.

Explanation:

The last statement most appropriately elaborates the role of motor units in directing the force applied by the muscles. It correctly states that 'a one motor neuron excites a particular range of muscle fibers in every muscle. In the situation of extra force required, there is an activation of extra motor units that assists in arousing the extra muscle fibers to shrink.' This contraction of muscles fibers in the concept 'motor units' assists the body to handle the distinct forces exerted by the body muscles when various weights are lifted. Thus, option d is the correct answer.

Answers

They obtained freedom and formed their own government.

The advantages of the Asian and African colonies becoming independent from the imperialist countries is that they are free from their slavery and can select people from their own society to form a government. They make laws for themselves and use the resources to improve their standard of living while, on the other hand, the disadvantage of becoming independent from the colonies of the imperialist countries is that the government established by the imperial countries manages the country better than the local government.

Make a list of necessities for all over development of a nepal and write about anyone of them in detail

Answers

Answer:

The Nepal Development Update is produced annually with two main aims: to report on key economic developments over the preceding months, placing them in a longer term and global perspective; and to examine (in the Special Focus section) topics of particular policy significance. The Update is intended for a wide audience including policymakers, business leaders, the community of analysts and professionals engaged in economic debates, and the general public.

Explanation:

.

For Nepal to achieve its export potential, six key priorities need to be tackled. First, Nepal will need to reform the tourism sector to meet the expected changes to demand and preferences, following the pandemic. A quick and resilient recovery of the sector could come about through investments to improve planning, conservation, and resilient infrastructure. It would also entail coordination with the private sector to upgrade skills and develop nature-based tourism that is environmentally sustainable, with potential to support jobs creation and inclusive growth. Second, to attract FDI, crucial for integration into regional and global value chains, it will be important to simplify and streamline processes for multinationals setting shop in Nepal, as well as actively engage in economic diplomacy to attract FDI. Third, modernizing export promotion will require links to digitization, simplification of processes, skills development, and incentives for exporters. Fourth, a reduction of trade costs will be critical, particularly given the country’s landlocked location and the mountainous terrain. This would entail reducing border crossing congestion through upgraded infrastructure and streamlined procedures and processes. Similarly, reducing import duties – particularly on raw materials and intermediates – is crucial to ensure exporters have access to the most efficient inputs at world prices. Fifth, investments to improve phytosanitary infrastructure will be needed for increased standards and safety of exports. Sixth, measures to boost digital trade, and e-commerce in general – could potentially be a game changer for Nepal – through adopting a robust policy framework. This would include, inter alia, efficient domestic and cross-border digital payment systems, and consumer protection and data privacy regulations aligned with international good practices.

According to Karl Marx, _____ is part of a collective process in which the proletariat comes to identify the bourgeoisie as the source of its oppression.

Answers

Answer:

Revolution.

Explanation:

The proletarian revolution is, in Marxist literature, a violent and class-based political revolution with which the proletarian class sets out to overthrow capitalism and, in the first place, break its institutions. The proletarian revolutions are generally supported by the communists and, albeit with different aims, by the anarchists.

The proletarian revolution is an ineliminable concept of Marxism as a consequence of the impossibility of a reform capable of eliminating the capitalist relations of production within capitalism itself. In Marxist theory the proletarian revolution, to be truly capable of abolishing the capitalist mode of production, must have a strictly internationalist nature, even if the revolutionary process were to begin in the form of national anti-bourgeois revolutions.
