What is a purine and a pyrimidine? Name them.
Answer:
Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.

Which feature separates watersheds?
A.) basins
B.)bays
C.)ridges
D. )rivers
Answer:
c
Explanation:
C.) Ridges are the feature that separates watersheds.
What is watershed ?A watershed is a region or area of land that collects and drains water into a particular river, stream, or other body of water.
Ridges or high points of land are critical in separating watersheds because they provide the boundary or border between two adjacent watersheds. When rain falls or snow melts, the water will flow downhill towards the closest body of water.
However, if that body of water is separated from another by a ridge, the water will flow down opposite sides of the ridge, into different watersheds.
Ridges are created by geologic processes such as tectonic uplift or erosion, and can vary in size and height. In some cases, a single ridge can divide a large drainage basin into two or more smaller ones, each with its own unique set of characteristics and ecosystems.
The boundary or border of a watershed is formed by a ridge or high point of land that separates one watershed from another. Water that falls on one side of the ridge flows into one watershed, while water that falls on the other side of the ridge flows into a different watershed.

2. C. A selectively permeable
membrane separates solutions A and B. The
concentration of water molecules in Solution
B is higher than that in Solution A. Describe
how the water molecules will move.
3. A. How is active
transport different from passive transport?
3. B. What are transport proteins?
3. C. Explain why transport proteins
require energy to function in active
transport.
Answer:
1. Water(solvent) molecules travel from A across the cell membrane / semi permeable membrane to B until the concentrations of A and B become equal.2. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.3. A transport protein is a protein that serves the function of moving other materials within an organism.
4. Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. ... transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.

1. One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic
information is passed among those types of molecules. Include the results of the processes of
transcription and translation
Answer:
Transcription uses a strand of DNA as a template to build a molecule called RNA. The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein building machines.

This was simulation. What are some variables that this peppered moths simulation does not address?
Answer:
The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

Carbon is stored in
A.Trees and other living things
B.Oceans
C.Underground in soil and fossil fuels
D.All are correct
Answer:
all are correct
Explanation:
Carbon is also found in the atmosphere where it's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.
A skateboard manufacturing company has had problems with the wheels on its skateboards cracking and causing injuries. An engineer for the company knows of a material that he thinks will make the skateboards safer. What would be the best step for the engineer to take next?
He should publish a report about the innovation and its impact on public safety.
He should conduct tests using computer models to determine the safety impact.
He should immediately begin producing all skateboards with the new material.
He should convert production of half of the skateboards to use the new material.
Answer:
He should conduct tests using computer models to determine the safety impact.
Explanation:
The other ones either use the material without testing it to make sure it is safe first or publish a report without knowing it's impact on public safety
Example of how organisms that were previously thought of as related are actually more genetically related to organisms outside their species?
Answer:
Explanation:
Examples includes the relationships between chimpanzees, gorillas and humans. It is actually believed that the chimpanzees are more closely related to humans. About 99% of ther genome is thought similar to humans while for the gorillas about 98%.
But then, it is thought that chimpanzees and gorillas should be closely related to each other than to humans, but comparison of their genomes has shown that across 15% of the gorillas genome, they share a closer relationship with humans than with chimpanzees.

Answer:
B. A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots.
A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.
What do you mean by Hardy-Weinberg equilibrium?The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.
