how does federalism allow for the peaceful distribution of government authority
Answer:
Federalism limits government by creating two sovereign powers
Explanation:
—the national government and state governments—thereby restraining the influence of both. Separation of powers imposes internal limits by dividing government against itself, giving different branches separate functions and forcing them to share power.

Fossils are usually found in Sedimentary rock.
sedimentary rock
Explanation: Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand, silt, or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock. Limestone and sandstone are types of sedimentary rock that commonly have fossils.

what are the sections on chromosomes? genes or DNA?
Answer:
genes
Explanation:dna whatttt
Answer:
Each section of a chromosome that contains the code for the production of a particular protein is called a gene . Each chromosome is made from a single molecule of DNA, but when a cell is ready to divide, the DNA copies itself, then coils and condenses to form the chromosomes that we see in micrographs .

Soil is a renewable resource that can be used in a sustainable manner.
Answer: Soil is a non-renewable resource. Its preservation is essential for food security and our sustainable future Soil is a finite resource, meaning its loss and degradation is not recoverable within a human lifespan.
Explanation:
Which option contains all of the other options listed?
gene
chromosome******
chromatid
centromere
Answer:
The chromosome contains all of the other options listed.
Explanation:
In eukaryotes, the complete chromosome is composed of only one lineal and extremely long DNI molecule. DNA is intimately associated with two types of proteins: histones, which are structural proteins, and non-histone proteins that mediate different functions of DNA. DNI associated with histones is called chromatin. Histones are responsible for packaging the DNI molecule.
In the interphase, before cellular division, chromatin is in a diffuse, lax, uncondensed state. When cellular division is about to happen, chromatin begins to condensate, and the chromatin strand generates a copy or clon so both of the daughter cells can get the same genetic information. At the beginning of the prophase, DNI is condensed in a well-defined chromosome formed by two sister chromatids. In metaphase, two chromatids joined by a centromere form the typical chromosome.
So, one chromosome is composed of two sister chromatids condensated and joint by the centromere. It looks X-shaped.
Genes are located in chromosomes, specifically in the DNA strand.

A plant is the most balanced need for water within its need for carbon dioxide and oxygen. It’s too much water is lost, the stomata will close. How does this affect the plants ability to regulate levels of carbon dioxide and oxygen?
Answer:
it helps regulate them and keep them level going through the state of transpiration
Explanation:
to prevent too much water lost a plant will close it's stoma to store that water, this process is called transpriation. if the stoma is open it will dry out the plant.
so a plant losing water in reaction they will close their stoma which is homeostasis, homeostasis is balance. so for example u go through homeostasis when it's hot outside it results in u sweating, why? cause your body is trying to cool down and regulate it's self.

What food substance do plants produce during photosynthesis?
Answer:

Explanation:
Plants, unlike animals, can make their own food. They do this using a process called photosynthesis . During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light.

Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage.

Answer:
I hope this helps
Explanation:
When a cell needs to make proteins, it looks for ribosomes. Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains. Ribosomes are special because they are found in both prokaryotes and eukaryotes.

This woman is riding a bicycle down a hill at a constant speed and in a straight line. Which change will increase the speed of the bicycle?
A. An added force of 20 N to the side of the hill B. Added forces of 30 N up the hill and 20 N down the hill
C. Added forces of 30 N up the hill and 30 N down the hill
D. An added force of 20 N down the hill
An added force of 20 N down the hill will increase the speed of the bicycle, stronger gravity is applied to things with higher masses, hence option D is correct.
What condition if a bicycle down a hill at a constant speed?A force that unites things. You stay on the ground thanks to the Earth's gravity, which also causes things to fall. Everyone and everything is affected by gravity.
Gravity is the force that pulls the cyclist down toward the ground. Riding the bike ahead on a completely level road encounters very little resistance from the effects of gravity.
Cyclist gains speed even when they are not pedaling because the potential energy produced by a hill's height is converted into an equivalent increase in kinetic energy.
Therefore, an added force of 20 N down the hill is correct.
