Neurotransmitters are released from secretory vesicles in neurons by a process called exocytosis.

Exocytosis is a form of active transport that occurs in cells in which a material is transported to the outside of this cell, being an active process the cell requires energy to carry it out.

Through this transport molecules are released outside the cell, it happens in cells that secrete substances such as glands or neurons to release their intravesicular content.

In exocytosis, the vesicles generated inside the cell will be transported to the membrane and will fuse with porosomes to secrete their content into the extracellular space.

Therefore, we can confirm that neurotransmitters are released from secretory vesicles in neurons by a process called exocytosis.

The smallest number of individuals that would still allow a population to be able to persist or grow, ensuring long-term survival is referred to as a minimal viable population.

In the field of ecology, we can simply define minimal viable populations as the smallest number of viable populations of a species living in an area. The species reaching a minimal viable population still have the capability to grow itself and ensure survival in an area.

The minimal viable population of a species is important for an ecologist to make research. Through a minimal viable population, an ecologist can determine which factors of an ecosystem help a population in survival and which ones act as its disruption.

Bar graphs are used to interpret results in an experiment by comparing the change of the dependent variable under different scenarios. D) on dark-colored soil with full moonlight.

A bar graph represents the relationship between two variables, the dependent and the independent one.

Usually,

Bars represent how the dependent variables react or respond to changes in the independent variable.

These charts are used to make comparisons. This means that by looking at the different bars, the researcher can to compare how the dependent variable responds under different scenarios of the independent variable. For instance, in which situation the bar is higher or shorter.

Bar graphs turn out to be an easy and reliable way to interpret results in an experiment.

Now let us analyze this example,

The researcher compares how many mice were caught by the owl under different scerarios: different substrate color, under moonlight or not, and according to their coat color.

The dependent variable is the number of caught mice, which depends on coat color, moonlight, and substrate color.

The independent variables are coat color, moonlight, and substrate color. Any change in them will affect the dependent variable.

Notice that even when the researcher can not manipulate the coat color, this is also an independent variable.

The question asks under which conditions would a dark brown mouse be most likely to escape predation at night?

Well, to answer it, we just need to compare the bars height.

Since the question ONLY asks about brown mice, we will limit out interpretation to brown bars.

The bar that expresses the conditions under which brown mice managed to scape predation is the shortest one, because it tells us about the lowest number of individuals caught by the owl.

When two firms combine, whose products and production levels are the same, then this is known as Horizontal Integration. Vertical Integration is when a firm takes over another firm or firms, that are at different stages on the same production path.

Horizontal Integration is a kind of business expansion strategy, wherein the company acquires the same business line or at the same level of the value chain so as to eliminate competition to a greater extent. Conversely, Vertical Integration is used to rule over the entire industry by covering the supply chain. It implies the integration of various entities engaged in different stages of the distribution chain.

The greatest advantage of horizontal integration is that it eliminates competition between firms, which ultimately extends the market share of the company. Conversely, Vertical Integration results in lowering the cost of production and wastage.

Although inflammation is a natural process that helps the body repair and protect itself from harm, it needs to be treated when it lasts for more than a few days or weeks. Inflammation in the joints is a symptom of arthritis.

An example of an anti-inflammatory medicine is corticosteroids. Treatment for rheumatologic conditions such lupus, vasculitis, and rheumatoid arthritis is widespread (inflammation of the veins). Explicit corticosteroids combine prednisone and cortisone.

Glucocorticoids (GCs) are frequently used to treat cancer, autoimmune conditions, and inflammation. For instance, cortisol boosts the production of glucose from non-carbohydrate sources like proteins, increasing the amount of glucose that is available for use as fuel.

Ecological problem is one of the most important issues nowadays. Human activities have a negative impact on the environment. Humanity currently faces problems with air, water, and lands pollution, unreasonable agricultural systems, deforestation, and others. As a result, the number of available natural resources is decreasing. Another negative consequence of human activities is the process of global warming and global climate changes. These changes affect the whole Earth and might result in adverse consequences for people and wild nature

Another important action we perform to improve the situation with water is avoiding water pollution. Our family refused to use cleaning detergents with phosphates as it is known that these substances are harmful to human health. Moreover, it is difficult to eliminate these compounds from water. Therefore, phosphates in the water get to nature and poison living organisms. Thus, it is better to use detergents without phosphates. It helps to keep the healthy and to reduce water pollution

Except for water pollution, there are a lot of other problems that need to be solved. One of them is waste deposits. These deposits occupy a large area. Different wastes need different (however, always significant) times to decompose. Besides, while decomposing, a lot of harmful compounds appear. These compounds poison the land and can get to the water. In the last decades, a lot of programs of waste separation appeared. People are asked to separate the waste: to combine plastic with plastic, organic with organic, and paper with paper. Different wastes are treated in different ways, which allows cutting pollution. For example, plastic can be remolded and used again, while it requires hundreds of years for its degradation in nature. Moreover, during this process, a lot of harmful products release (Law and Thompson 144). Thus, it is better to separate plastic material and recycle it. It would be even better not to use plastic at all, and when it is possible, try to use biopolymers instead.
