Answer:

population - community - ecosystem - biosphere

Explanation:

The correctly sorted level of organization of an ecosystem from the least inclusive to the most inclusive would be from population to community to ecosystem and finally to biosphere.

A population consists of a group of organism of the same species living in a particular area at a particular time and capable of interbreeding to produce fertile progeny.

A community represents different population of organisms that are interacting with one another. Several populations make up a community.

An ecosystem consists of different communities of organisms that are interacting with themselves and the non living component of the environment.

A biosphere consists of all regions of the earth where living organisms can be found. It consists of different ecosystems that make up the earth.

Hence, the population is least inclusive, followed by the community, then the ecosystem and finally the biosphere.

Answer:

valence electrons an element has in its outer shell, the easier it is to complete.

The most electron shells an element has, the easier it is to fill its outermost shell.

Explanation:

Non metals atoms bond to other elements by sharing or completing the valance electrons in other element. This is easily made when the other element lacks a small number of electrons, for example with Hydrogen it has 1 valance electron because of that it is easier to bond with other elements.

Pain signals often have two components: an acute sensation of "first pain" which is felt almost immediately after an injury, and

o-na [289]

Answer:

This suggests that neurons that send the signals that we perceive as first pain Myelinated Tpye A-delta___, and neurons that send the signals that we perceive as second pain Unmyelinated-Type C.___.

Explanation:

Physiologically, primary afferent neurons that innervated the the touch, pain, temperature,and pressure receptors in the effectors to input sensory signals to the spinal cord and the brain are categorized based on their diameter, sizes, and nature of myelination. Based on this;

A-alpha has the largest diameter, myelinated, and sensitive to sensation from the muscle cells

A-beta are next in diameter, myelinated and sensitive to sensation of touch.

A-delta followed in diameter, and size. They are mylinated, and sensitive to pain and temperature.

C-fibres are least in diameter, they are unmyelinated, but sensitive to pain, touch and temperature.

Therefore, if the speed of conduction,of action potential in a neuron depends on the diameter(thickness) and myelination of the axon(saltatory conduction) :

''then, acute sensation/ first pain should be transmitted by the A-delta fibre. While the the slower/second pain should be transmitted by the slower unmyelinated - C-fibres''.

Enzymes can be denatured unfolded by what environmental factors

erastova [34]

Enzymes can be denatured unfolded by heat or chemicals.

<h3>What are enzymes?</h3>

Enzymes are proteins that are found in living organisms which are able to increase the rate of chemical reaction and remains unchanged at the end of the reaction.

The factors that can denature enzymes include heat and chemicals. This is because:

Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. When the enzyme loses its shape, it is said to have been denatured.

These environmental factors can alter the pH level of the enzyme.

Therefore, for an enzyme to perform its functions, the external factors that affects it's activities must be normal and favorable.
