Neurotransmitters are chemical messengers that are released from the neuron as the action potential reaches the end of the axon. The correct statement is the third statement.

Neurotransmitters are chemical messengers and they relay signals between the neurons. As the action potential reaches the end of the axon, the vesicles consisting of neurotransmitters fuse with the presynaptic membrane and neurotransmitters are released in the synapse.

These neurotransmitters then bind with the receptors at the postsynaptic neuron. The effect of the neurotransmitter depends on the kind of the receptor and the kind of the neurotransmitter involved. The resulting effect can be either the inhibition or excitation of the postsynaptic neuron.

The entry of neurotransmitters through K+ channels into neurons does not lead to the rising phase of the action potential. The rising phase of the action potential is triggered by the opening of voltage gated ion channels that cause an influx of sodium ions.

Neurotransmitters are not released from muscle cells to activate motor neurons in the presence of botulinum toxin; rather, it leads to the inhibition of neurotransmitter release from muscle cells causing muscle paralysis.

Neurotransmitters are chemical messengers released in response to the action potential which is generated by the movement of sodium and potassium ions across the axon membrane. They are released into the synapse when the action potential reaches the end of the axon. This  release is inhibited in presence of botulinum.

In conclusion, neurotransmitters are released from neurons when the action potential reaches the end of its axon.

Explanation:

Surface currents in the ocean can affect the temperature of the surrounding air and land areas they flow past, influencing regional climates. Warm ocean currents can bring warmer and more humid weather to the adjacent land, while cold ocean currents can have the opposite effect, cooling the air and land temperatures. This can have significant effects on local ecosystems, agriculture, and economies.

Answer:

Media used for cell growth contain proteases and a divalent cation chelator to help cells adhere to the surface.

Explanation:

Mammalian cell structure is the process where animals cells are grow in vitro in a flask or dish. The methods, equipments, reagents and supplies use in this type of culture prevent contamination and maintain cell culture purity. Protein enzymes like Serine protease breaks the cellular matrics interaction between the cells. In cell culture, the focal adhesions that are anchoring the cell to the culture dish is cut away. Most trypsin solutions for cell culture also contain EDTA which acts as a chelator for calcium. When calcium is remove from a solution, cadehrin that hold cells to each other break down and cells become separated from each other.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

If a solution has a pH of 5, the concentration of the OH- in the solution would be 1 x \(10^-^9\) M.

Recall that:

pH + pOH = 14

The pH is 5 in this case, hence:

  5 + pOH = 14

         pOH = 14 - 5

                     = 9

Also, recall that:

pOH = - log{OH}

Substitute pOH = 9:

         9 = - log{OH}

  {OH} = 1 x \(10^-^9\) M

Therefore, the OH- concentration of a solution with a pH of 5 would be 1 x \(10^-^9\) M

Mitochondria evolved from aerobic bacteria while chloroplasts evolved from cyanobacteria.

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. A eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.

Chloroplast evolutionarily derives from a primitive cyanobacteria that was engulfed by non-photosynthetic cells and, progressively, after losing most of its DNA, became the actual chloroplast that retains only a fraction of the original cyanobacterial genes. Chloroplasts of plants and algae are currently believed to originate from a cyanobacterial endosymbiont.

One environmental factor that could influence natural selection and decrease genetic diversity is habitat destruction or fragmentation.

When natural habitats are destroyed or fragmented due to human activities such as deforestation, mining, or urbanization, it can significantly alter the environmental conditions that organisms depend on for survival. This can lead to the loss of biodiversity and the homogenization of the gene pool within a population.

As habitats are destroyed or fragmented, species are forced to adapt to new environmental conditions or migrate to other areas. This can create selective pressures that favor certain traits over others, leading to the evolution of specialized adaptations that may not be present in other populations. Over time, this can lead to reduced genetic diversity within a population and even the loss of unique genetic variants that were once present.

Explanation:

The main skeletal features used to construct a cladogram include the presence or absence of specific bones/structures, bone shape/structure, dental characteristics, skeletal adaptations, and skull morphology.

Cladograms are phylogenetic trees that illustrate the evolutionary relationships between different organisms. When constructing a cladogram, various skeletal features can be used as characters to determine the branching patterns and common ancestry among organisms. Here are some main skeletal features used in cladistic analysis:

Presence or absence of specific bones or structures: The presence or absence of certain skeletal elements, such as wings or limbs, can provide insights into evolutionary relationships.

Bone shape and structure: Comparing the shapes, sizes, and structures of bones can help identify shared characteristics and infer common ancestry.

Dental characteristics: The structure and arrangement of teeth, including the type and number of teeth, can provide information about evolutionary relationships and dietary adaptations.

Skeletal adaptations: Features like the presence of a notochord, presence of a bony skeleton, or modifications for specialized locomotion (e.g., wings, fins, limbs) can be used to infer evolutionary relationships.

Skull morphology: Examination of the skull, including the shape of the cranium, presence and structure of specific cranial bones, and jaw structure, can help determine evolutionary relationships and functional adaptations.

By analyzing these skeletal features and comparing them across different organisms, cladistic analysis aims to identify shared derived characteristics (synapomorphies) that indicate common ancestry and to construct a branching pattern that represents the evolutionary relationships between the organisms being studied.
