Pedomorphosis is the term given to an organism that becomes able to reproduce before the body is an adult (somatic development).

Pedomorphosis, is the characteristic an organism that its juvenile or larval traits can appear later  in the life. Pedomorphosis is an substitutive process to metamorphosis in which adults retain larval traits at the adult stage. This process is more common in newts and salamanders, where larvae influence s.e.x.ual maturity without losing their gills.

Upon fertilization, the egg and sperm fuse to form a single cell called an A) zygote.

Fertilization and meiosis—the process of making haploid cells from diploid ones—are two key aspects of the life cycle that are shared by all species that reproduce sexually.

A zygote is formed when the sperm and eggs are combined during fertilization. With the help of mitosis, the zygote divides into a mature human. The first diploid cell that forms when male and female gametes fuse to form an embryo is called a zygote.

During the first week of fertilization, the zygote stage is formed.

Answer:

Eating invasive species can be seen as a way to control their population and reduce their impact on the ecosystem. However, it is not a solution to the problem of invasive species on its own and it does not fully address the issue.

One reason for this is that it may not be feasible to harvest and consume enough of the invasive species to have a significant impact on their population. Additionally, in some cases, invasive species may contain harmful chemicals or toxins, making them unsafe to eat.

Another reason is that eating invasive species does not address the root cause of their introduction and spread. Invasive species are often introduced through human activities such as trade, transportation, or development. Therefore, preventing the introduction and spread of invasive species in the first place, through measures such as stricter regulations, monitoring and early detection, is a more effective approach to controlling their populations and mitigating their impacts.

Additionally, it is important to consider that many people do not have access to these invasive species and also it may not be culturally acceptable for some people to consume them.

In conclusion, while eating invasive species can be a way to control their population, it is not a complete solution to the problem and it should be used in conjunction with other methods such as preventing their introduction, monitoring and early detection and controlling their spread to effectively address the problem of invasive species.

At the peak of the action potential, the membrane potential is at its most depolarized state, meaning that the inside of the cell is more positively charged than the outside.

This is caused by the rapid influx of positively charged ions, such as sodium (Na+), into the cell. Therefore, at the peak of the action potential, sodium ions (Na+) are the most conductive.

During an action potential, the membrane potential of a neuron changes rapidly from a negative resting potential to a positive peak potential. This change in membrane potential is caused by the movement of ions across the cell membrane, which is controlled by ion channels.

At the resting potential, the membrane is relatively impermeable to positively charged ions, such as sodium (Na+), and there is a higher concentration of negatively charged ions, such as chloride (Cl-), inside the cell. As a result, the cell acquires a negative charge inside and a positive charge outside.

Epigenesis is the theory which states that organisms are derived from the assembly and reorganization, somewhat de novo, of substances in the egg.

The process through which organisms, including plants, animals, and fungi, evolve from a seed, spore, or egg through a number of phases during which cells divide and organs emerge is known as epigenesis (or, in contrast to preformationism, neoformationism). Aristotle coined the term "epigenetics" in his essay On the Generation of Animals. The historical rejection of epigenesis was hampered by creationist ideas of life's origins, despite the fact that it seems evident in the genetic era of today. However, a protracted and contentious dispute among biologists in the late 18th century led to the eventual replacement of the long-standing preformationist theory with epigenesis.

The process that allows this kind of change in the bacterial population is called antibiotic resistance. It occurs when bacteria evolve mechanisms to survive exposure to antibiotics.

This can happen through various mechanisms such as mutation or acquisition of resistance genes from other bacteria through horizontal gene transfer. The mutations that give the bacteria immunity to penicillin are examples of genetic changes that can confer antibiotic resistance. When the bacteria with these mutations are exposed to the antibiotic, they are able to survive and reproduce, passing on the resistance to their offspring. This leads to a shift in the population towards antibiotic-resistant strains. Overuse and misuse of antibiotics can also increase the rate of antibiotic resistance, as it creates more opportunities for the bacteria to be exposed to the drugs and evolve resistance.
