What is the measured output force of a pulley system if the Mechanical Advantage is 0.48 and measured input force is 10N?
Answer:
Output force is 4.8 N
Explanation:
A pulley is a simple machine made of a grooved wheel with a rope or cable wrapped around it. Pulleys are used in the transmission of energy or motion.
The input force is also known as the applied force while the output force is the force exerted on an object by a simple machine.
The mechanical advantage of a pulley is the ratio of the output force to the input force.
Mechanical advantage = output force / input force
Substituting:
0.48 = output force / 10
Output force = 4.8 N

Answer:
Por difusión.
Explicación:
Los organismos simples como las bacterias, los protozoos, las algas y los hongos no tienen un sistema de excreción especializado. Hicieron la excreción a través del proceso de difusión en el que los materiales se mueven de la región de alta concentración a la región de menor concentración. Debido a esta difusión, hay una gran cantidad de material de agua presente, por lo que el material de desecho se mueve desde el interior del cuerpo al entorno exterior a través de la membrana presente alrededor de su cuerpo y este proceso de difusión también se utiliza para la absorción de nutrientes.

This process is based on a chemical reaction that occurs when the warm exhaust gases from the coal-fired boiler come into contact with limestone.
When the warm gas comes into contact with the limestone slurry a chemical reaction occurs between the Sulphur Dioxide (SO2) in the gas and the limestone.
This reaction removes the SO2 from the flue gases and converts the limestone into Calcium Sulphite.

Ferns have vascular tissue, an adaptation to life on land, but they have an ancestral reproductive trait that tends to limit them to moist habitats. What is it?
Answer:
The correct answer is - flagellated sperm.
Explanation:
In ancestral trait that is flagellated sperm in ferns that were limited to moist habitat has sperms that must swim to the eggs. This is why ferns often require splashing water for the movement of sperm to points near female gametangia during reproduction.
Fern now adapted the vascular system to get life on the life and they are not limited to the water bodies, however, flagellated sperm is the ancestral reproductive trait.

What is the relationship between natural selection and population?Natural selection can cause microevolution (change in allele frequency), which causes fitness-enhancing alleles to become more common in the population. Fitness is a measure of reproductive success (how many offspring an organism leaves for the next generation, relative to others in the group).
Another factor that limits the growth of populations is densification. This means that a large number of individuals present at the same time in the same area reduces the availability of resources for the population as a whole, increasing the mortality rate and reducing reproductive success.

Explanation: HOPE IT HELPS
Using the words "selection pressure" and "fitness", explain how natural selection causes populations to change over time.
Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.

The majority of nitrogen fixation happens when _____ converts atmospheric nitrogen(N2) into ammonia(NH3).
1. Fungi
2. Plants
3. Bacteria
Answer:
3.bacteria
Explanation:
The majority of nitrogen fixation happens when bacteria converts atmospheric nitrogen(N2) into ammonia(NH3).
hope it is helpful to you
The majority of nitrogen fixation happens when bacteria convert atmospheric nitrogen (N2) into ammonia (NH3). Bacteria live in symbiotic associations such as Rhizobium, but some live freely and fix nitrogen.
How is atmospheric nitrogen fixed?The atmospheric nitrogen is fixed by bacteria, which convert the atmospheric nitrogen into ammonia. There are many bacteria involved in this process.
Some bacteria live in symbiotic relationships with the roots of legume plants and capture nitrogen. Example: Rhizobium converts the nitrogen into ammonia, and the nitrogen enters living creatures when they eat the legumes. The leguminous plant makes the soil more fertile due to this process.
This process is aided by bacteria such as Azotobacter and Clostridium. Azotobacter is an aerobic bacteria, while Clostridium is an anaerobic one. The nitrogen is important for living organisms, as nitrogen is important for DNA, RNA, and protein synthesis.
Hence, Bacteria is the correct answer, as bacteria convert the atmospheric nitrogen (N2) into ammonia (NH3). option 3 is correct.
