Which event might cause the carrying capacity of a population to change?
tamaranim1 [39]

Answer:

Carrying capacity can be described as the maximum number of population of a species that a particular habitat can hold.

There are a number of events which effect the carrying capacity like:

  • Environmental changes:

Environmental changes like weather conditions might become favorable for a species in a habitat. It might be that a certain weather condition raises more food for a species. Hence, the carrying capacity would increase.

It might be conditions like drought make the availability of nutrients scarce for a population of species. In this case, the carrying capacity of the ecosystem would decrease.

  • Other organisms :

It might happen that other species might come to live in the particular area. That species will deplete the availability of resources and cause the carrying capacity to decrease.

  • Water supply:

If adequate amount of rain fall occurs in an area, it might cause the carrying capacity of a species to increase as there will be more water. But if the water supply becomes scarce, the carrying capacity would decrease.

omeli [17]
The tiny structures  inside of cells, such as Ribosomes or chloroplasts that have specialized roles are called organelles. These structures are found in the cytoplasm of eukaryotic cells and are enclosed with a membrane. These tiny structures are not present in prokaryotes like in bacteria.

One example of how applied science has had a direct effect on daily life is the presence of vaccines. Vaccines to prevent diseas
Mashutka [201]

Vaccines are a boon in eradicating various lethal diseases and increase the immunity of the people. The development of vaccines started with the understanding the cell itself, various pathways that regulate its fate. The immunology, a branch of biological science, gave the idea of the working of the defense or the immune system of the body, and of the various specia cells that function for it. This led us to the discovery of antibodies and antigens. Vaciines are artificial means of injecting antigens into the body to generate antibodies beforehand, so that the immune system remembers producing it at the time disease causing agent strikes us.

Thus, we can summarise that STEM research or core science research has led to innovations that have shaped our lives and lifestyle to contribute to an overall good social health.

In what stage does the skin blister allowing bacteria to enter the site of the pressure ulcer
dimaraw [331]
I think it is stage 2
At stage two, the skin breaks open, wears away, or forms an ulcer, which is usually tender and painful. The sore expands into deeper layers of the skin. It may appear as a scrape, blister, or a shallow crater in the skin. At times this stage looks like a blister filled with clear liquid. Also at this stage some skin may be damaged beyond repair or may die.
