what is the name of the stored energy molecule our cells and bodies need?
The energy used and stored by cells comes from adenosine triphosphate (ATP). A nitrogenous base, ribose sugar, and three serially linked phosphate groups make up the nucleoside triphosphate structure of ATP.
Cells need chemical energy to do three broad types of tasks: to drive metabolic events that would not happen naturally; to transport necessary molecules across membranes; and to perform mechanical labour, such as moving muscles. Chemical energy cannot be stored by ATP; lipids and carbohydrates such as glycogen are better at doing so. Energy is transformed from storage molecules into ATP when the cell needs it. ATP transports energy to areas of the cell where energy-intensive processes are occurring.

The features of Mexican long-nosed bats are evidence of natural selection because the features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success. So the correct option is Option C.
In biology, Charles Darwin,an English naturalist and evolutionary biologist, gave the definition of survival of the fittest as this, “a natural process resulting in the evolution of organisms best adapted to the environment”. This is based on a theory known as evolution theory proposed by Charles Darwin. By this theory he described how the natural process of selection works among the different organism.When we talk about fitness from the perspective which is biological, is that it’s not solely the physical fitness that we emphasize, but reproductive fitness and reproductive success serve as crucial deciding factors for overall fitness.

Antiseptic surgery was pioneered by B. Lister.
Joseph Lister was a British surgeon widely regarded as the founder of antiseptic surgery.
After studying the work of Louis Pasteur, who demonstrated the germ theory of disease, he developed the concept of antiseptic surgery in the 1860s. Lister recognised that the presence of microorganisms in the wound caused many surgical infections, and he developed techniques for sterilising surgical instruments and creating a sterile environment in the operating room to prevent infections.
Lister's antiseptic surgery techniques revolutionised the field of surgery and significantly reduced the incidence of surgical infections. His legacy lives on today through the use of antiseptic techniques in all aspects of healthcare.
Antiseptic surgery is a surgical technique that employs the use of antiseptic agents to stop and regulate the growth of microorganisms that can result in infection in the surgical wound.

during what phase does the nuclear membrane reform around the chromosomes?
Telophase. Mitosis' final stage, with many of the procedures seen during prometaphase reversed.
The nuclear membrane reforms around the chromosomes clustered at the cell's poles, the chromosomes uncoil and become diffuse, and the mitotic spindle disappear.
Telophase is the final stage of both mitosis and meiosis in a eukaryotic cell. Telophase occurs when prophase and prometaphase are reversed.
Telophase reverses the effects of prophase and prometaphase (disintegration of the nucleolus and nuclear membrane). As the chromosomes reach the cell poles, the nuclear envelope reassembles itself around each set of chromatids, nucleoli reappear, and the chromosomes begin to decondense back into the expanded chromatin that is present.

An example of two different species is the African elephant (Loxodonta africana) and the Asian elephant (Elephas maximus).
Although both species belong to the same family (Elephantidae) and share many physical characteristics, such as their large size and long trunks, they are considered distinct species because they have significant genetic and morphological differences.African elephants are larger and have longer tusks than Asian elephants, and their ears are shaped like the African continent, while Asian elephants have smaller ears that are rounded. In terms of behavior, African elephants tend to live in large herds, while Asian elephants are more solitary or live in smaller family groups.
While African and Asian elephants can interbreed in captivity, their offspring, called hybrids, are usually sterile and unable to produce viable offspring. This is a common characteristic of species, as they are defined as groups of organisms that can interbreed and produce fertile offspring. The distinct genetic and morphological differences between African and Asian elephants, as well as their inability to produce fertile offspring, confirm their classification as separate species.

a sudden global decrease in the number of species over a relatively short period of time, called is
A sudden global decrease in the number of species over a relatively short period of time, called is Mass extinction.
A mass extinction is typically described as the extinction of about three-quarters of all species on Earth during a "short" geological time span. Given the immense length of time that has passed since life first originated on Earth, "short" is defined as anything less than 2.8 million years.
Major extinctions are relatively uncommon. They induce severe changes in the Earth's biosphere, creating possibilities for surviving species and their progeny as they adapt to the new conditions, claiming abandoned ecological niches or filling newly formed ones. Comet and asteroid impacts, extensive volcanism, climatic changes, fast changes in topography and ocean currents, or a combination of these elements can all produce mass extinction events.
In Earth's history, there have been five particularly massive extinction events. Each one is distinguished by a noticeable fall in biodiversity that occurs in the fossil record and lasts for tens of millions of years later. With the commencement of each major extinction event, the relatively abrupt loss of enormous numbers of species significantly simplified or caused the collapse of many of Earth's biological ecosystems.
Throughout time, surviving species took ecological niches formerly held by other species (some of which may have preyed on or competed with them), and also filled new niches as ecosystems recovered and new biological groups emerged.
