Species richness (S) is the number of species within a defined region. It's merely a numerical characteristic of an ecosystem. The species richness of a region is obtained through sampling or via a census.

Because a region is defined by the observer, species richness has been further categorized into three components to account for changes in spatial scale. They are Alpha diversity, Beta diversity and Gamma diversity.

One important thing to keep in mind is the difference between species richness and species diversity. Several factors affect small-scale species richness, including geographic factors such as the regional species pool, dispersal distance and ease of dispersal, biological factors such as competition, facilitation, and predation as well as environmental factors such as resource availability etc.

Explanation:

In 1953, polio cases decreased, while in 1945, they increased. The first polio vaccine, produced by Dr. Jonas Salk, was presented in 1955.

We may use history to learn how the polio vaccine affected cases. Polio was highly contagious and caused thousands of cases and outbreaks before vaccinations. The mid-1950s polio vaccine introduction changed the fight against polio.

Polio cases plummeted once Dr. Albert Sabin's 1960s oral polio vaccine (OPV) became widely available. Mass immunisation campaigns reduced disease spread and new infections.

While the polio vaccine has reduced polio incidence worldwide, some countries may still experience outbreaks due to low vaccination coverage, inadequate healthcare infrastructure, or difficulties reaching certain populations. However, polio immunisations have reduced the global disease burden.

Las plaquetas son responsables de la coagulación de la sangre.

Explanation:

Answer:

Invertebrates can have bilateral or radial symmetry, or they can be asymmetrical. Bilateral symmetry means that the animal is arranged in the same way on both sides. Radial symmetry means the body parts are arranged in a circle around a central point.

The plasma membrane is selectively spongy, which indicates that some molecules can pass via it while others cannot. The penetrability of the plasma layer relies upon the size, charge, and extremity of the particles that are trying to go through.

Depending on the concentration gradient and the membrane's transporters, proteins and glucose can pass through the plasma membrane via facilitated diffusion or active transport because they are small enough and have the right properties.

Large carbohydrate molecules, on the other hand, are too big to pass through the plasma membrane through diffusion or facilitated transport. They are regularly too huge to possibly be perceived by the carriers in the film and can go through by means of endocytosis or exocytosis, where the layer frames a vesicle around the particle to move it across the film.

In conclusion, the selective permeability of the plasma membrane and the size of large carbohydrate molecules prevent them from passing through the membrane.

No, all the fragments are not the same size, If two people have different DNA sequences at specific restriction sites, the restriction enzymes will cut their DNA into various length fragments.

Differences in the number of DNA fragments found between two or more people may also exist. Gel electrophoresis is a method for separating DNA fragments (or other macromolecules like RNA and proteins) depending on size and charge.

Because DNA is negatively charged, it will gravitate towards the positive electrode. As a result, separation will be based on fragment size. Smaller DNA molecules go the fastest and farthest, followed by bigger ones.

B. All cells must have a cell membrane, cytoplasm, DNA, and ribosomes. I hope it helps :)

Answer:

the answer would be A.

Explanation:

this would be because a cell is the smallest living thing, after cells, tissues are the next smallest thing, then it is an organ, because different tissues make up an organ, then multiple organs will create an organ system, and multiple organ systems create an organism.

The structure of the body has several levels of the organization, and the sequence is cell → tissue → organ → organ system → organism, hence option A is correct.

The human body's biological functions are preserved at several levels of structural organization. The following levels are included: chemical, cellular, tissue, organ, organ system, and organismal.

The lowest unit of life is a cell. A tissue is made up of a variety of unique cells. Organ systems are made up of related organs that are made up of tissues. A living thing or organ is made up of various organ systems.

Therefore,  any organism's cell is its fundamental structural and operative unit. Multicellular organisms are made up of cells, tissues, organs, and organ systems, which are composed of groups of similar cells, tissues, organs, and organ systems.
