Answer:
Prophase
Explanation:
Cytokinesis begins in anaphase in animal cells and prophase in plant cells, and terminates in telophase in both, to form the two daughter cells produced by mitosis.
For a neuron to function, an input of free energy from ATP is required to set up the sodium and potassium ion concentration gradients such that a signal can be propagated down the axon of a neuron without the necessity of ATP. The system could have worked the opposite way. The neuron could have used ATP to move ions across when a signal was being propagated and then allow natural diffusion to return the ions to their respective sides of the membrane. What advantage does the organism have using ATP up front
Answer:
The lack of ATP would slow nerve responses to generate an action potential
Explanation:
Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.

Through their roots, plants absorb water and mineral nutrients, returning organic matter to the soil through root exudates, litterfall, and roots. Thus, they can increase organic matter in the soil.
What increases soil quality?Through their roots, plants absorb water and mineral nutrients, and they return organic matter to the soil through litterfall, roots, and root exudates.
Avoid over-tillage while preparing seedbeds, and maintain the seedbed as coarse as you can to keep the aggregates big enough to hold gases and carbon. Any organic material input enhances soil quality. Organic matter enriches the soil with carbon while preserving the separation and integrity of the soil aggregates.

Explain how this experiment showed that gene flow was not the cause of antibiotic resistance.
Answer:
Due to no transfer of resistance allele.
Explanation:
The gene flow was not the cause of antibiotic resistance because the characteristics can't be transferred from one generation to the next generation. The organisms are evolved to become an antibiotic resistance due to their environmental conditions and this resistance quality is only present in the existing population and the alleles that are responsible for this resistance can't be transferred from the bacteria to the next generation so the experiment showed that gene flow was not the cause of antibiotic resistance
In this relationship, the candiru is a fish that lives in freshwater. Humans use the freshwater to swim in. Humans may urinate in the water. The candiru detects fresh urine and swims up the urethra or anus of the human. In the urinary tract, it spreads spines out and lodges itself in the human. It will then suck on tissue and blood from the urethra from the human over a long period of time. The human is hurt and could die from this, if left untreated over time.

What are the types of vascular plants? How do they reproduce?
crytogams - this type of vascular plant reproduces by spore.
phanerogams - this type of vascular plant reproduces from the seeds, hence also named as seed plants.
Angiosperms - this type of vascular plant reproduces flowers and fruits
Gymnosperms - this type of vascular plant reproduces cones and seeds only.
Answer:
Vascular plants are plants that have roots, stems, and leaves. They have a vascular system that is responsible for the distribution of water and nutrients. This system is made up of the xylem (responsible for distributing the raw sap to the leaves) and the phloem (responsible for transporting the processed sap to the rest of the plant). Within this group we have: pteridophytes (Many plants do not produce flowers. They are also known as cryptogams. They reproduce through spores) and spermatophytes (they are vascular plants that produce seeds and, therefore, are the most evolved).
Explanation:
Vascular plants are those that have a “corm” made up of root and stem (stem and leaves), as well as a conduction system made up of xylem and phloem for transporting water and photosynthates. Pteridophytes are vascular plants that do not produce seeds. Within the vascular plants they are the simplest plants at a structural level, since they do not have the complexity linked to the production of these seeds, which are what allow the sexual reproduction of plants. Spermatophytes are the vascular plants that produce seeds. These seeds generated by the flowers, when they fall to the ground after dispersing, germinate and give rise to a new plant. This presence of seeds that can be spread by the wind or by animals is what has allowed these plant species to colonize the world.

The diversity of species greatly affected the ecosystem stability if more species are present in he ecosystem. The abiotic factors also plays an important role in the stability of an ecosystem because these abiotic factors causes changes in the ecosystem environmental conditions.
