"Biological" redirects here. For other uses, see Biological (disambiguation).
Biology is the scientific study of life.[1][2][3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.[1][2][3] For instance, all living organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.[1][2][3] Finally, all living organisms require energy to move, grow, and reproduce, as well as to regulate their own internal environment.[1][2][3][4][5]
Biology deals with the study of life and organisms.

bottom: Goliath beetle and tree fern
Biologists are able to study life at multiple levels of organization.[1] From the molecular biology of a cell to the anatomy and physiology of plants and animals, and to the evolution of populations.[1][6] Thus, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they used.[7][8][9] Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, and perform experiments to satisfy their curiosity about the world around them.[1]
Life on Earth, which emerged before 3.7 billion years ago,[10] is immensely diverse. Biologists have sought to study and classify the various forms of life, from prokaryotic organisms such as archaea and bacteria to eukaryotic organisms such as protists, fungi, plants, and animals. These various living organisms contribute to the biodiversity of an ecosystem, where they play specialized roles in the exchange of energy and nutrients.

BRAINLIEST: A satellite was in two separate crashes. In both crashes, the satellite had the same mass. Engineers want to know about the speed and direction of the satellite after the crashes. Why would the crash affect the motion of the satellite, and which crash caused a greater change in motion for the satellite?
Answer:
Crashing into the asteroid would cause the satellite to slow down, stop, or reverse direction, because it is a force in the opposite direction to the satellite's motion. Whichever crash was a stronger force would cause it to change motion more. It takes a stronger force to change the velocity of a more massive object.
Explanation:
Big change occur in the motion of the satellite when it is hit by a big and heavy object.
The crash greatly affected the motion of the satellite because the other object comes to the satellite in opposite direction which slower down the speed and sometimes also reverse the motion of the satellite.
That crash will bring great change in the motion of the satellite which is hit by a big and heavy object whereas if the object is small than it only slow down the speed of the satellite so we can conclude that the interaction with greater object will greatly affected the motion of the satellite.

Viruses and bacteria are two types of microorganisms that can cause disease in humans and other animals. While they share some similarities, they also have many differences in terms of their structure, replication, and the ways in which they cause disease.
Bacteria are single-celled organisms that come in many different shapes and sizes. They can be either beneficial or harmful to humans, depending on the species and the circumstances. Some bacteria live in the human gut and help to digest food, while others can cause infections such as strep throat, pneumonia, and meningitis. Bacteria have a cell wall that provides structural support and protection, and they reproduce through a process called binary fission, in which one cell divides into two identical cells.
Viruses, on the other hand, are not technically alive, as they cannot replicate or carry out metabolic processes on their own. Instead, they rely on host cells to reproduce and spread. Viruses are made up of a core of genetic material (either DNA or RNA) surrounded by a protein coat called a capsid. Some viruses also have an outer envelope made up of lipids. Viruses attach themselves to host cells and inject their genetic material into the cell, which then takes over the host's machinery to produce more virus particles.
While bacteria can cause disease by invading and damaging host tissues, viruses typically cause disease by hijacking host cells and using them to produce more virus particles. Some common viral infections in humans include the common cold, flu, and HIV.
Both bacteria and viruses can be treated with antibiotics or antiviral medications, but these treatments can be less effective or even ineffective if the microorganism has developed resistance to the medication. Prevention measures such as vaccinations and good hygiene practices are often the best way to control the spread of these microorganisms.
In summary, bacteria and viruses are two distinct types of microorganisms that can cause disease in humans and animals. Bacteria are single-celled organisms with a cell wall that can reproduce through binary fission, while viruses are not technically alive and rely on host cells to replicate. Understanding the differences between these microorganisms is essential for preventing and treating infectious diseases.

___________ is a protein that stabilizes existing actin micofilaments
Tropomyosin is a protein that stabilizes existing actin microfilaments.
Tropomyosin is a two-stranded, alpha-helical coiled-coil protein that twists along the actin filament surface, spanning seven actin monomers. It stabilizes existing actin microfilaments by preventing actin polymerization and depolymerization.Tropomyosin is a long, thin, fibrous protein that binds to the actin molecule's grooves.
It stabilizes actin microfilaments by promoting the formation of microfilaments and inhibiting the depolymerization of microfilaments by sterically blocking actin filament association. Tropomyosin's coiled coil binds to a continuous groove on the surface of actin monomers, which serves as a scaffold for troponin to attach to tropomyosin.The tropomyosin molecule stabilizes the actin filament by preventing the myosin head from binding to the actin monomers, causing muscle contraction.

Calcium has several important roles, including its role as a signaling molecule, its involvement in tight junctions, and neuronal excitation. What other important physiological role does calcium have
Calcium indeed has several important roles in the human body, including its role as a signaling molecule, its involvement in tight junctions, and neuronal excitation. Another important physiological role that calcium has is its involvement in muscle contraction.
Calcium plays a crucial role in the process of muscle contraction by binding to the protein troponin, which is present on the actin filaments within muscle cells. This binding leads to a conformational change in the troponin-tropomyosin complex, exposing the myosin-binding sites on the actin filaments.
When calcium ions are released into the muscle fiber, they bind to the protein complex called troponin, causing a conformational change that enables the myosin and actin filaments to interact and generate force. This process allows for the contraction of both skeletal and cardiac muscles, which is essential for movement and the proper functioning of the heart.
Additionally, calcium is important for bone health and is involved in many enzymatic reactions throughout the body.
This allows the myosin heads to bind to the actin filaments and generate force through the sliding filament mechanism, ultimately leading to muscle contraction. Calcium is then actively pumped back into the sarcoplasmic reticulum, allowing the muscle to relax. This entire process is known as excitation-contraction coupling.
