The correct order of the cells from the outer region of a seminiferous tubule is Spermatogonium > Spermatid > Secondary spermatocyte > Primary spermatocyte.
What is seminiferous tubules?Seminiferous tubules are located in the testes. Meiosis occurs in this region. The process of spermatozoa happens here, and the germ cells are converted into spermatozoa. They are present in large numbers in the lobule of the testis.
The process occurs in steps, and the order of converting the germ cells into spermatozoa is Spermatogonium > Spermatid > Secondary spermatocyte > Primary spermatocyte.
Thus, the correct order is Spermatogonium > Spermatid > Secondary spermatocyte > Primary spermatocyte.

Explain the reciprocal relationship between human society and limiting factors.
Answer:
A limiting factor is a situation or condition that determines the speed or growth of a certain biological or social process, due to the fact that only a limited amount of it is available.
Therefore, a limiting factor is one that places a limit on the development of a certain characteristic within society. A clear example within biology is the lack of drinking water sources, which is a limiting factor for the development of population settlements, as occurs in the Sahara.
Thus, the existence of limiting factors puts a brake on the unrestricted development of human society, conditioning its development to the adaptation of individuals to the natural conditions of the environment.
Possible Answer:
Human society makes modifications to the environment to suit its needs. Humans can live in large numbers in harsh environments that do not necessarily support the population because of these modifications. Humans cannot, however, change the fact that they are affected by limiting factors. They can change the limiting factors in a specific area, but are still influenced by limiting factors in a larger area, either by region, or globally. Food, water, and energy supplies are limited and will only support a certain human population size. If the human population exceeds this size than disease, famine, and other limiting factors will naturally limit the population size.

Before the clincial trials, drugs are tested in the laboratory. The laboratory trials are not trials on people. What is the drug tested on in these laboratory trials?
Answer:
Explanation:
Before the drugs can be tested on humans they have to be tested using a few other methods first. Firstly they have to complete computer model tests and human cells grown from stem cells. After that, they are tested on animals to see even more possible side effects and how well the drug does. And after the animal and computer and lab tests they can be used in clinical trials.

A researcher places part of a plant cell in a beaker of water. She observes that the plant leaves release bubbles of gas when she shines a light on the beaker. The leaves do not release gas when the beaker is placed in the dark. Based on her observations, which of the following is the most logical inference?
Answer:
Explanation:
a
A researcher places part of a plant cell in a beaker of water. She observes that the plant leaves release bubbles of gas when she shines a light on the beaker, and this is due to the plants going through photosynthesis, which is in Option B.
What is the product and the bubble formation in photosynthesis?The bubbles that are seen in water when plants are kept in light are actually oxygen bubbles. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. The oxygen produced during photosynthesis is released into the surrounding environment as a waste product. When plants are submerged in water, this oxygen can accumulate and form bubbles. This process is called bubbling. The bubbles that are seen in the water are an indication that the plant is actively photosynthesizing and producing oxygen.
Hence, she observes that the plant leaves release bubbles of gas when she shines a light on the beaker, and this is due to the plants going through photosynthesis, which is in Option B.

community-based treatment programs.
Answer:
Drug therapies and community-based treatment programs
Explanation:
Before the 1950s there was more of an institutionalization approach and they didn't have an alternative for many patients. They had some success with psychotherapy but not nearly as much as we have today. But when they introduced new drug therapies and added community-based treatment programs many mental health hospitals were not filled with patients anymore. Many serious problems were now kept under control with simple pills and a good treatment program.
In the 1950s the mental health hospitals were closed and the patients with mental illness were sent back home to receive the treatments in their communities.
The correct answer is:
Option A. Drug therapies and community-based treatment programs.
The asylums were closed in 1950s as:
Psychotherapy and some institutionalized approaches were present to treat the patients. There were no other alternatives.The incorporation of drug therapies and community-based treatments led to the emptiness of the asylums and therefore, they were closed.The treatments were under control and community-based therapies helped in the treatment of mental patients.Thus, the asylums were closed in the 1950s due to the introduction of drugs and community-based therapies.
Therefore, option A is correct.
