Which relays instructions from the CNS to muscles more quickly, the somatic nervous system or the ANS? The somatic motor system relays instructions to muscles more quickly because it involves only one motor neuron, whereas the ANS uses a two-neuron chain. Moreover, axons of somatic motor neurons are typically heavily myelinated, whereas preganglionic autonomic axons are lightly myelinated and postganglionic axons are nonmyelinated.

Answers

Answer 1

The somatic motor system relays instructions to muscles more quickly because it involves only one motor neuron, whereas the ANS uses a two-neuron chain. Moreover, axons of somatic motor neurons are typically heavily myelinated, whereas preganglionic autonomic axons are lightly myelinated and postganglionic axons are non myelinated.

The lateral component of the somatic motor system controls the premotor interneurons and motoneurons of the distal muscles. This component consists of two pathways—the lateral corticospinal and the rubrospinal pathways. In humans, the lateral corticospinal pathway subserves the control of the independent movements of the extremities. It controls the motoneurons via direct projections as well as indirectly via strong projections to the laterally located premotor interneurons.

The motoneurons innervating the muscles of the distal limbs receive the strongest direct projections from the motor cortex. This descending system enables humans to make most refined and extremely complex movements, such as independent finger movements and speech, the most complicated motor performance. In most mammals, both the lateral corticospinal and the rubrospinal pathways are important, but in humans the rubrospinal pathway seems to be irrelevant. The somatic motor system relays instructions to muscles more quickly because it involves only one motor neuron, whereas the ANS uses a two-neuron chain. Moreover, axons of somatic motor neurons are typically heavily myelinated, whereas preganglionic autonomic axons are lightly myelinated and postganglionic axons are non myelinated.

Consider two kinesin motor proteins at the mitotic spindle midzone: kinesin A is a tetrameric motor that walks toward the plus end of both microtubules to which it is attached via its motor domains; kinesin B, on the other hand, walks toward the minus end of one microtubule while it is attached to another microtubule via its tail domain.How do these motors affect the length of the spindle?
A. They both work to shorten the spindle.
B. Kinesin-5 works to shorten the spindle whereas kinesin-14 works to lengthen it.
C. Kinesin-5 works to lengthen the spindle whereas kinesin-14 works to shorten it.
D. They both work to lengthen the spindle.

Answers

Answer:

C. Kinesin-5 (kinesin A) works to lengthen the spindle whereas kinesin-14 (kinesin B) works to shorten it.

Explanation:

Kinesins are microtubule-based motors localized in the mitotic spindle in order to ensure the correct segregation of the chromosomes during cellular division. These proteins are classified regarding their sequences at the core motor domains which determine their motility. Kinesins can move along microtubules in opposite directions, walking toward the plus end (i.e., the end that grows more rapidly) or moving toward the minus end. Recently, it has been shown that opposite forces between kinesin-5 (plus-end-directed) and kinesin-14 (minus-end-directed) microtubule-based motors regulate the length of the spindle during cellular division. Kinesin-14 is a minus-end-directed motor protein that walks along microtubules from plus- to minus-end, while kinesin-5 is a plus-end-directed motor protein that walks along microtubules from minus- to plus-end, and thereby they work to shorten and lengthen the mitotic spindle, respectively.

Adenosine Triphosphate is a nucleotide molecule with three phosphate groups joined in a row. ... When the third phosphate group is broken away from the ATP molecule, the stored energy is released. This, smaller amount of energy can then be safely used in other cellular reactions of life processes. ATP (adenosine triphosphate) has three phosphate groups that can be removed by hydrolysis to form ADP (adenosine diphosphate) or AMP (adenosine monophosphate). The negative charges on the phosphate group naturally repel each other, requiring energy to bond them together and releasing energy when these bonds are broken. 5. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds. When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). 6.

A. These are examples of competition because the organisms are fighting for resources.

B. These are examples of predation because the organisms are trying to take each other’s food and homes.

C. These are examples of predation because lions and cheetahs eat woodpeckers and squirrels.

D.These are examples of competition because no organisms are helped or harmed.

Answers

Answer:

a

Explanation:

both of the cases the organisms are fighting for a resource

A. These are examples of competition because the organisms are fighting for resources.

How Competition and predation are two different types of relationships ?

Competition and predation are two different types of relationships that can exist between different organisms in an ecosystem. Competition occurs when two or more organisms are fighting for the same resources, such as food, water, or shelter.

This can occur within or between different species. In the example given in the question, woodpeckers and squirrels compete for nesting rights in the same holes and spaces in trees, while lions and cheetahs compete for the same antelope and gazelle prey.

On the other hand, predation occurs when one organism (the predator) hunts, kills, and consumes another organism (the prey). This type of relationship is often seen between carnivores and herbivores, or between animals and insects. In the example given in the question, lions and cheetahs are predators that hunt and consume antelope and gazelle prey.

It is important to note that in both competition and predation, one organism may benefit while the other is harmed.

For example, in predation, the predator benefits by getting food while the prey is harmed by losing its life. In competition, one organism may gain access to the resources while the other loses out, which can affect their ability to survive and reproduce.

A large island near the mainland

Explanation:

A large island has a greater number of species, a greater interaction between them and a greater number of natural elements. All of this is capable of promoting biological specialization on a large scale, allowing new species to emerge more quickly than on a small island. Although a small island may also have great biodiversity, that island has fewer factors that promote the creation of new species, in addition to having fewer species interacting and creating new species.

Question:
Using a specific example, discuss the importance of electrons in the transfer of energy in living systems.​

Answers

Answer: The transfer of energy in the form of electrons allows the cell to transfer and use energy in an incremental fashion. The principle electron carriers are NAD+ and NADH because they can be easily oxidized and reduced, respectively.

Explanation:

Electrons are very significant in the steps of energy transfer in the living body cells.

When the electrons are displaced from the molecule it gets oxidized which results in a reduction in the potential energy.

Electrons transfer is very important because most of the power is stored in the atoms in the form of electrons that are required for cell functioning.

The chief electron transporters are NADH and NAD⁺ they reduce and oxidizes the compounds.

NADis oxidized and NADH is the reduced form of the molecules.

The living structures cannot save a large amount of energy and hence they collect them in the form of ATP and electrons.

Although their model was wrong, what assumption made it reasonable to build a model with the bases projecting to the outside

Answers

Answer:

Nitrogenous bases contain the genetic information, their amount is variable among different species, and the arrangement of these bases is also variable among different species

Explanation:

Both Watson-Crick and Pauling's DNA models considered that DNA nitrogenous bases (i.e., Adenine, Cytosine, Thymine and Guanine) contain the genetic information that determines the characteristics of living organisms. Moreover, both DNA models also considered that nitrogenous base composition varies between species, as well as the arrangement of these bases in the DNA chain also varies between species. Based on these features, Linus Pauling considered that a model where nitrogenous bases would be arranged on the outside of the DNA molecule would be easier for the DNA molecule to be replicated, transcribed, or repaired. Although incorrect, Pauling's DNA triple helix model was fundamental to develop the helical (double-stranded) structure of DNA, which was finally discovered by Watson and Crick in 1953.
