Explain the production of urine, include the processes of Ultra filtration and selective reabsorption.
Answer:
Urine Is 95% Water
Explanation:
The Glomerulus Filters Water and Other Substances from the Bloodstream
The Filtration Membrane Keeps Blood Cells and Large Proteins in the Bloodstream
Reabsorption Moves Nutrients and Water Back into the Bloodstream
. Waste Ions and Hydrogen Ions Secreted from the Blood Complete the Formation of Urine

There is a belief that there are as many neurons in the human body as there are stars in the Milky Way Galaxy. Do you believe this? How would you react on this?
Answer:
I do believe this. If you take the amount of neurons in the average adult body and expand them to the size of a say a blueberry It would expand to be the approximately the size of the sun
Explanation:
The given statement is true. It is a surprising fact that helps a person to believe that his brain has the power to take him beyond expectations.
What are Neurons?These are the nerve cell that is found in the brain and nerve tissue in the body.It has been estimated that there are 100 billion neurons in the human brain which is about the number of stars in our Galaxy.The human brain is very complex and this complexity comes from such a huge number of neurons.
Therefore, the given statement is true. It is a surprising fact that helps a person to believe that his brain has the power to take him beyond expectations.

Convection occurs because heated material becomes ____________________. A less dense and rises B denser and rises C denser and sinks D less dense and sinks
Answer: A less dense and rises
Explanation:
Convection is a type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases due to presence of less number of mmolecules per unit volume. As the hot liquid becomes less dense, it starts moving upwards.
Thus convection occurs because heated material becomes less dense and rises.

Use your knowledge of inheritance (the passing of traits from parents to offspring) to explain why
these twins look so different even though they have the same parents. Why aren't they identical? In
your answer you should include your knowledge of gametes (sperm and egg), chromosomes, and
variation
Answer:
Fraternal twins can be different genders because they are two completely different eggs getting fertilized; but even two same gender fraternal twins do not look completely alike. Whereas for identical twins since one egg is splitting into two, the two cells have the same exact DNA make up and chromosomes.
I also believe the technical part of it is to do with genetics, like ressesive and dominant genes, because they can be the same gender, ex. both girls and one has blue eyes, fair skin, and blonde hair, the other twin has brown eyes, black hair and tan skin. The parents could be part of the genes but there is also grandparents maybe the mom's mom has blonde hair and blue eyes, with fair skin. But the dad he has brown eyes, black hair and tan skin. The moms genes were recessive, but the grandma's genes were dominant.

How does the structure of DNA explain chargaff's rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.
What is Chargaff's rule?Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.
Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.

Overgrazing reduces grass cover and negatively impacts the soil health by reducing it's ability to hold water . How can Overgrazing be prevented and support a more sustainable use of grasslands ?
A. Allow developers to buy rachlands for housing .
B. practice moving confined cattle every few days
C. Allow unlimited animals to graze in a given area to reach carrying capacity.
D. practice grazing an area of land at the same stage of plant growth each year .
Answer: C. Allow unlimited animals to graze in a given area to reach carrying capacity.
Explanation: I choose this as the answer because the animals grazing in the wrong parts be part of the reason the soil can't hold the water it needs, so allowing animals in a particular area that's less of a problem with Overgrazing would be helpful

How did the invention of the microscope contribute to knowledge about 1p living things?
Answer:
It made it possible for people to discover and learn about cells.
Explanation:
The cell is the basic unit of structure and function of all living beings. A cell can also be defined as a morphological, functional, and reproductive unit of all living beings.
Every living organism is made up of one or more cells. All cells are created from an existing cell. A cell is the smallest unit that has all the characteristics of life. A set of cells of similar or the same appearance, embryonic origin, and function is called tissue.
The science that studies the cell is called cytology. There are organic and inorganic compounds in the cell. Of the inorganic compounds, water and salts are the most common. Organic compounds in the cell contain carbohydrates, fats, and proteins.
