What two simple machines is a stapler made up of?
1. wheel and axle and lever
2. lever and pulley
3. wedge and screw
4. wedge and lever
Answer:
4. wedge and lever
Explanation:
Simple machines are mechanical devices which make our work easier. Examples are : lever, wedge, wheel and axel, pulley, screw and an incline plane.
A stapler is a made up of a level which is the handle part and a wedge which are the staples.
A pulley is a simple machine that has one or more wheels connected with a rope in a loop to make lifting of loads easier because it changes the direction of force applied/pull thus multiplying the force applied. A stapler does not have the wheel and the rope thus answer choice 1 and 2 are incorrect.
A screw is a simple machine that applies torque on a shaft to produce a large axial force on the load. It utilizes the conversion of rotational motion to a linear motion and a torque to a linear force. A stapler mechanism does not involve rotational motion or rotational force, hence answer option 3 is incorrect.
A stapler is made up of a combination of two simple machines: the wedge and the lever. The correct option is 4.
A stapler utilizes a wedge to perform its primary function. The wedge is the part of the stapler that drives the staple through the paper. It has a sharp, triangular shape that allows it to exert a large amount of force over a small area, making it easier to pierce through the materials.
The stapler also incorporates a lever mechanism. The lever is the long arm of the stapler that is pushed down to drive the wedge and staple into the paper.
By applying force at one end of the lever, a mechanical advantage is gained, allowing the user to apply a smaller force to produce a greater force output at the other end, making it easier to staple multiple sheets of paper together.
Therefore, The correct option is 4.

Mutations are important because they bring about
A) death if the organism in which they develop
B) genetic variation needed for a population to evolve
C) benefits for the individual, not for the population
D) hardey-weinberg equilibrium within a population
Answer:
B) genetic variation needed for a population to evolve
Explanation:
Mutations are important because they bring about the genetic variation needed for a population to evolve.
Mutation brings about changes in the DNA sequence of an organism. Most times, mutation results when an organism tries to adapt and evolve to unfavorable conditions. Mutation can originate from mistakes in DNA sequencing. It can also be due to environmental influences.What do the Mitochondria and

474
Answer:
474
Explanation:
took test
The Forest Service and three other federal land management agencies currently oversee 474 wilderness areas totaling more than 111.7 million acres as part of the National Wilderness Preservation System. Thus, option D is correct.
What importance of wilderness areas in an ecosystem?The risk of extinction is reduced by wilderness, with the risk being doubled for species found outside those places.
Additionally, a variety of species can be found in both wilderness and non-wilderness places, and their ability to survive depends heavily on the wilderness's undisturbed habitat.
The advantages of wilderness are many. There is so much more to wilderness than just a place to camp, trek, or fish.
Our water and air are purified by wilderness. It serves as both a habitat for wildlife and a source of income for nearby towns.
Therefore, 474 wilderness areas are there in the United States.

How often do spring and neap tides occur?
twice a day
twice a month
every 27.3 days
every 24 hours
Spring and Neap rides occur twice a month
Spring and neap tides occurs twice a month.
What is the difference between spring and neap tides?A neap tide refers to a period of moderate tides when the sun and moon are at right angles to each other. A spring tide is a common historical term that has nothing to do with the season of spring.
In the period between the two spring tides, the moon faces the Earth at a right angle to the sun. When this happens, the pull of the sun and the moon are weak. This causes tides that are lower than usual. These tides are known as neap tides.
Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range (difference in water level between high and low tide) is much larger in a spring tide than in a low tide.

All of the following contribute to the decrease of biodiversity EXCEPT conservation of natural resources.
What do you mean by biodiversity?Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level.
Scientists often speak of three levels of diversity: species, genetic, and ecosystem diversity. In fact, these levels cannot be separated. Each is important, interacting with and influencing others. Changes at one level can cause changes at other levels.
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the eye.

Predict what would happen to the wolf and elk populations if there was a drought that caused many of the plant species to dry up and/or die.
Answer:the elk would die because there would be no plants left and then the wolf would die to because there would be no more elk
Explanation:
If a drought were to cause many plant species to dry up and die, it would have indirect effects on the populations of wolves and elks, which are interconnected through a predator-prey relationship.
The drought leads to a scarcity of water, which affects plant growth. Many plant species, including grasses and shrubs that serve as food sources for elks, dry up and die due to the lack of water.
With the decline in plant food sources, the elk population would face food scarcity. The reduced availability of vegetation would result in limited feeding opportunities for elks, potentially leading to malnutrition and weakened individuals.
Therefore, it's important to note that the specific outcome may vary based on the severity and duration of the drought, the overall ecosystem resilience, and the presence of alternative food sources or migration possibilities for elk and wolf populations.

Predation
Answer:
Predation
Explanation:
Answer:
Predation
Explanation:
Predation is the interaction between two organisms in which one organism is harmed which is prey and other organism is benefited who is predator.
In predation, predator kills the prey and consumes it to get energy. Predators by killing their pray control the population of prey in nature and help the ecosystem to remain in a balanced position.
For example, lions hunt deer and eat them. Here lion is the predator and deer is the prey and lions control the overgrowth of deer in the wild by preying in deer. Therefore the correct answer is Predation.
