Answer:
pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.

A person with brown eyes has children with a person with blue eyes. The genotype of the brown eyed person is unknown;
however, it is known that brown is dominant over blue. If all of their children have brown eyes, what is most likely the
genotype of the brown eyed parent?
.
A. Bb
.
B. None of these
C.BB
D. bb
Answer:
C.
Explanation:
On the punnet square, with genotype BB, you'd be highly likely to have brown eyes unless the person with blue eyes has a dominant blue eye genotype.
A person with brown eyes has children with a person with blue eyes. If all the children are brown-eyed, that means the genotype of the parents is BB. So, the correct option is C.
What is a punnet square?
A square diagram is used to predict the genotype and thus the phenotype of the offspring when the genotype of the parents is known.
In a punnet square, the gametes formed from the genotype of one parent are written across the top row and gametes formed from the genotypes of another parent are written across the left corner.
The gametes are then crossed with each other to predict the genotype and thus the phenotype of offspring.
If one parent is brown-eyed, their genotype could be either BB or Bb. If the other parent is blue-eyed, their genotype is bb.
Now if all their children are brown-eyed. The genotype of the brown-eyed parent would be BB.
If the genotype of the brown-eyed parent was Bb, there would be two offsprings with genotype Bb and two offsprings with the genotype bb.
Therefore, the correct option is C

How do scientist use fossils to study organisms
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
Explanation:
Analyze evidence from the lesson regarding the relationship between the structures found in cells and functions carried out by cells related to protein formation and transport or the capture, storage, and usage of energy. Choose a cellular function and make a claim about how structural features of the cell support the function. Use specific examples and details to support your claim.
Answer:
This is vvv
Explanation:
One of the cellular functions is making food/creating energy. Plant cells do this the best as they have chloroplasts that can turn sunlight, water, and carbon dioxide into glucose and oxygen via photosynthesis. This glucose is then turned into usable energy when it is transported to the mitochondria where it is turned with oxygen into carbon dioxide and ATP via cellular respiration. The ATP is taken around the cell and distributed to where it is needed via the Golgi apparatus.

When two species from different lineages independently evolve similar characteristics because they occupy similar environments, we observe ______.
Answer:
The correct answer is - convergent evolution.
Explanation:
When two organism are not monophyletic or had different lineages, evolve independently same type of characteristics in due to the adaption to the similar environmental conditions termed as convergent evolution in evolutionary biology.
Wings of insects, birds, and bats and their flight has similar nature due to the environmental condition but have different lineages, are one of the example of convergent evolution.
Thus, the correct answer - convergent evolution.

Scientists can identify cells by categorizing the different features of a cell by noting down the shape, color, and other physical features. This aspect of science is known as_________ Observation Inference Hypothesis Controlled Experiment
Answer:
Observation
Explanation:
The aspect of science that has to do with the recording of color, shape, and other physical features in order to identify a cell would be observation.
Observation in science is the collection of data via perception or through the use of scientific instruments. Perception generally involves the use of human senses such as sight, touch, taste, and hearing to collect data in order to arrive at a conclusion.
The color, shape, and other physical features of a cell requires a perception of sight. Hence, it involves observation.

What are proteins?Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.
Moreover, every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development in children, teens, and pregnant women.
Serious protein deficiency can cause swelling, fatty liver, skin degeneration, increase the severity of infections and stunt growth in children. While true deficiency is rare in developed countries, low intake may cause muscle wasting and increase the risk of bone fractures.

What have you learn about atoms and the universe
Answer:
Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.
Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei. This all took place within the first few minutes of the universe's existence
