According to the steps in which primary succession occurs, the correct orderos events is 22, 24,  21, 19, 23, 20.

Primary succession refers to changes that occur in an open space with no living organisms, such as a bare rock exposed due to a retreating glacier, volcanic activity, or an intense fire. If previous species were inhabiting this area, after the event, nothing is left.

In those cases where there is an alteration or disturbance at a site that opens the area, it allows new species to grow. With time, new species arrive and manage to establish themselves again. The order of the establishment depends on the strategies of each of the species to survive.

First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish themselves in the open space. Pioneers modify the habitat. They make it more suitable for the establishment of later species, converting rock into fertile soil.

As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the soil,  making it better with time. New species arrive. Habitat modification keeps on going while new species establish.

Herb species and srubs grow in these areas. Finally, trees appear. They produce shadows, alter the temperature, and humidity, fertilize the soil, competing for resources. Competition becomes more frequent between species.

The first species are eventually eliminated by competition, but new species keep appearing and competing for resources. This sequence continues until the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.

1) 22- A plot of farmland is abandoned.

2) 24- Pioneer species, such as dandelion, take root in the soil.

3) 21- Grasses and bushes appear.

4) 19- Shade from grasses and shrubs provide protection for tree saplings.

5) 23- Tree saplings grow and increase the amount of shade in the area.

6) 20- Pioneer species and other small plants are unable to grow in the shade and die.

One feature of a mineral's definite chemical composition is that it cannot contain atoms from more than one element. This means that the mineral is composed of a specific combination of atoms from one or more elements, and that this combination is unique to that mineral. Option 4

For example, the mineral quartz is composed of silicon and oxygen atoms in a specific ratio, and no other elements are present. This is because minerals are naturally occurring substances that have a specific chemical composition and crystal structure. They are formed through various geological processes and are often found in rocks and other geological formations.

The chemical composition of a mineral is determined by the types and amounts of atoms that make up its structure, and this composition is usually constant and predictable. In addition to having a definite chemical composition, minerals also have other unique features that distinguish them from one another.

These include their physical properties, such as hardness, color, and luster, as well as their crystal structure and other characteristics. By studying these features, geologists and mineralogists can identify and classify different minerals and learn more about the processes that form them. Option 4 is the correct answer.

The lactose operon is like a group of genes that help break down lactose, which is a sugar found in milk. And if a bacterium wants to use lactose for energy, it needs to break it down first.

So, if scientists wanted to engineer a bacterium that could triple the digestion of lactose in the operon, they might add or subtract certain parts of the operon to make it more efficient at breaking down lactose. For example, they might add extra copies of genes that are responsible for breaking down lactose, or they might remove parts of the operon that are slowing down the digestion process.

But, like, to be honest, I'm not really sure exactly which parts they would add or subtract. I think it would depend on the specific bacterium they're working with and the specific genes in the lactose operon. And the scientists would need to do a lot of experiments and testing to figure out what works best.

Residual parent material is the rock and soil that is still located in its original location and is weathered. Transported parent material is material that is carried and deposited by natural agents such as water, wind, or glaciers. The effect of these different types of parent material on soil formation can be significant.

Residual parent material usually contributes to the development of soils with qualities similar to the parent rock. The breakdown of rock into smaller particles through weathering enables the formation of soil horizons and the release of minerals that influence soil fertility.

The physical and chemical characteristics of soils derived from this form of parent material are often similar and homogeneous, allowing for predictable fertility and properties. Transported parent material, on the other hand, can introduce a diverse range of materials to a given area, resulting in variations in soil composition, texture, and fertility.

The transportation process can blend different types of sediment, resulting in the formation of heterogeneous soils with different characteristics. Transported parent material can also be exposed to weathering processes, altering its original composition and resulting in soils with varying degrees of fertility.

While transported parent material can increase the diversity of soil properties in an area, it can also make it difficult to predict soil characteristics, particularly in areas where different types of sediment have been deposited. The relationship between parent material and soil development is complex, with both the initial characteristics of the material and the surrounding environment influencing soil properties.

In general, residual parent material contributes to the development of homogeneous soils with predictable properties, while transported parent material can result in more diverse and heterogeneous soils.

Explanation:

To achieve her goal of growing a generation of only dark purple petunias, the gardener could use selective breeding to crossbreed two petunias that have the desired traits. In this case, she would breed two petunias that have the darkest shade of purple that she wants to achieve. By doing this, the offspring will have a greater chance of inheriting the desired traits, and the gardener can continue this selective breeding process over several generations to produce a stable and predictable variety of dark purple petunias.

The reason for breeding the two darkest purple petunias together is to increase the likelihood that their offspring will inherit the genes responsible for producing the dark purple pigment. By selectively breeding for this trait over multiple generations, the gardener can create a population of petunias with the desired color and other desirable traits.

The reduction in activation energy by an enzyme affects a chemical reaction by increasing the rate of the given chemical reaction.

Activation energy may be defined as the minimum amount of energy that is generally needed by the atoms and molecules of reactants in order to undergo a chemical transformation and form products. Activation energy is generally represented by an Arrhenius equation:

Enzymes may be defined as biocatalysts that perform the important function of increasing the rate of a chemical reaction without being consumed in the process. It may be thought that all cellular reactions and processes are mediated by enzymes.

This is accomplished by lowering the activation of energy of the reaction. As a result of this, the rate of a chemical reaction may be increased.

Therefore, the reduction in activation energy by an enzyme affects a chemical reaction by increasing the rate of the given chemical reaction.

The unofficial titles of some eras such as Age of Fishes, Age of Reptiles and Age of Mammals are really informative and they are not oversimplifications because these periods reflect the emergence of different taxonomic groups in the course of evolution.

The animal eras are periods during the geological time in which certain groups of animals appeared in the course of evolution, which results informative to determine how evolution (change) occurred due to natural selection.

For example, mammals emerged as a taxonomic group during the Cenozoic Era, which occurred approximately 65 million years ago and this period is known as the Age of mammals.
