Why are stone tools found on their own?
Stone tools are found on their own because they do not decompose and stay as they are.
What is the importance of stone tools in human history?In the broadest definition, a stone tool is any tool that is manufactured totally or mostly of stone.
Some stone tools were used for chopping fruits and roots as well as for cutting flesh and bone, removing bark from trees, and cutting into hides, or animal skins. A few of them served as handles. Some were used to create hunting spears and arrows.
Early human creations, such as stone tools and other artifacts, provide information on how people lived, interacted with their environment, and changed over time. Thousands of archaeological sites have been investigated, excavated, and dated during the last 2.6 million years.

How will restoring land to its original state after mining affect the final price of the mined resource?
Answer:
The price of the resource is increases.
Explanation:
The restoring of land to its original state after mining greatly affect the final price of the mined resource because the company who sells the mined resource also add the price of restoring of land which increases the price of the mined resource. The restoring of land also needs money and this money is paid by the company who did mining in that region so the company also add the amount of restoring of land when it sells its product or resource.
How does actin and myosin work together to help you lift an object?
Answer:
Muscle contraction thus results from an interaction between the actin and myosin filaments that generates their movement relative to one another.
Actin and myosin work together to help you lift an object in the following way:
Muscles are tissues of the musculoskeletal system that have the function of generating a force towards the bones with the ultimate goal of performing a movement.In order for this function to be carried out correctly, it needs proteins that are found inside the muscle fiber, these proteins are myosin and actin.The myosin head in the presence of ATP binds with the actin filaments, in order to generate a minimum slip that later becomes a coordinated and precise movement as lift an object.That is, myosin binds to the actin protein to generate the contraction of the muscles, and therefore the movements we make with our extremities.Therefore, we can conclude that actin is a cellular protein in muscles that is involved in muscle contraction when it connects with myosin.

In Marker Analysis, how are STRs related to alleles? Be sure to define each term (STR and allele) and explain how the two result in different band patterns when run in gel electrophroresis.
Answer:
The number of STR repeats is unique and therefore it is considered as an allele of that locus
Explanation:
Short Tandem Repeats (STRs), also known as microsatellites or simple sequence repeats (SSRs), are short DNA sequences with a size of 1-6 nucleotide bases which may be many times repeated in tandem. STRs localize in specific regions of the genome (loci) and therefore they are molecular markers. Gel electrophoresis a technique used to separate DNA fragments based on their size. In consequence, the pattern of STR repeats or 'alleles' obtained by electrophoresis can be used to identify individuals. In a gel electrophoresis, STR markers produce different bands that run more slowly or faster on the gel in different lanes according to their size (e.g., more slowly >> higher size of the STR sequence), and thereby STR alleles are unique and serve to identify individuals.
5. Why are fingerprints stronger individual evidence than nDNA?

The cod fish population has dropped in New England between 1982 until today. How
many times larger was the cod fish population in 1982 as compared to today?
0 it was 27x higher in 1982
it was 19x larger in 1982
it was 95x higher in 1982
0 it was 5x higher in 1982
Answer:
it was 27x larger in 1982
Explanation:
The cod fish population has dropped in New England between 1982 until today due to higher mortality rate. The population of cod fish in1982 is 80000 metric ton of spawning stock biomass while on the other hand, the population of cod fish in 2011 is 2500 metric ton of spawning stock biomass. This lowering of cod fish population is due to higher mortality rate so we can say that the population of cod fish was 27x larger in 1982.

They are decomposers that break down organic wastes and dead organisms into compounds used by plants for photosynthesis.
They are producers that make food by converting water and carbon dioxide into glucose and oxygen, using energy from the Sun.
They are autotrophs that use chemicals as an energy source to produce food when sunlight is not available.
They are heterotrophs that get their energy by consuming plants, herbivores, and other primary consumers.
The following is the best explanation of the role of fungi and slime molds in the rainforest food web is that they are decomposers that break down organic wastes and dead organisms into compounds used by plants for photosynthesis, as presented in the first option.
What is the significance of the decomposers?Decomposers are organisms that break down dead plant and animal matter and convert it into simpler substances that can be recycled as nutrients for the ecosystem and are a critical part of the ecosystem, as they play a vital role in the carbon and nitrogen cycles, help break down organic matter, making it easier for plants to absorb nutrients from the soil and this process helps to maintain the balance of nutrients in an ecosystem and supports the growth of new plants and animals.

A wave has a wavelength, L = 50m, and is traveling in water with a depth of 30m. It is a _________
Group of answer choices
deep water wave
medium water wave
shallow water wave
can't determine
Answer:
The answer to this question is medium water wave
The kind of wave described in the illustration would be a deep water wave.
According to definition, a deep water wave is a wave that occurs at water depths that is more than half the wavelength of the wave.
In this case, the wavelength of the wave is 50 m and the depth of the water is 30 m. Half of the wavelength of the wave would be 25 m.
Thus, the depth of the water is more than half of the wavelength of the wave. This effectively makes the wave a deep water one.

IN YOUR OWN WORDS I WILL GIVE BRAINYLIST WHOEVER ANSWERS THIS CORRECTLY!!!
Answer:
The wildlife habitat will be changed and poison the wild animals.
Explanation:
The resource consumption greatly affect biodiversity of different plants and animals on Earth because resources helps the organisms to survive. Organisms used resources such as food, space and water etc for growth and survival. If these resources are used up by humans so the biodiversity is negatively affected and the wildlife habitat is converted into agricultural and urban land. The biodiversity is also affected due to production of waste that cause pollution and poison wildlife.
