Answer:
Energy affects competition in the tropical rainforest due to the dense population of trees found in this region.
Trees are producers and they compete mainly for water, sunlight and nutrients. Sunlight provides the source of solar energy which is instrumental in its photosynthetic process.
The trees form canopies and create competition among the ones who have lower stems and branches while the ones with longer stems continue to grow taller due to the availability of sunlight.
Competition may also affect the organisms living in this region as they compete for food.
A scientist studies the DNA in corresponding genes of a platypus, a
beaver, and a duck. The DNA from which two species are most likely to be most
similar? Explain your answer.
Answer:
platypus and a duck has similar DNA.
Explanation:
There are certain similarities which are present between duck and platypus such as structure of beak or mouth, webbed feet and laying eggs in order to continue its generation. These three characteristic make the platypus and duck similar to each other. There is also one major difference is present which is that the platypus is the only mammal which lay eggs and feed baby with their own milk. Its tail structure is also different from duck.
The DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.
Sequence homo-logy refers to the level of similarity between nucleotide (DNA) sequences due to shared ancestry in the evolutionary history of life.The species that share a more recent ancestor exhibit a higher level of sequence homo-logy than unrelated species.In this case, the linear order of nucleotides in DNA from platypus and beaver are most likely to be most similar because they are mammals, while ducks are birds.In conclusion, the DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.

how does the virus use a host cell to make copies of itself
Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.
A red blood cell placed in distilled water will swell and burst due to the movement of Your answer: salt from the distilled water diffusing into the cell water molecules moving by osmosis into the cell water from the red blood cell moving into the distilled water
Answer:
Due to the movement of surounding water ijnto the cell.
Explanation:
A red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.
Osmosis is the movement of water that diffuses from a higher water concentration area to a lower water concentration area.
The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic to the red blood cell.The red blood cell will gain water, swell ad then burst.Thus, a red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.

Government websites use the domain suffix (.gov) which demonstrates that the information being provided is from the federal government (reliable).
Blogs are not reliable, especially if they are personal (unreliable)
While some commercial websites could be right, some can skew the truth to fit their perspective or lie for financial gain (unreliable)
Peer reviewed science journals provide studies and experiments, and use real examples (reliable)
if a disease killed all the seagulls what effect would this have on the food web?
Answer:
if the disease kills all the seaguells then it will affect the food chain negativleyy because the population of the species that would eat them (predator) will decrease dramatically and the fish ( what the seaguells eat ) there peopulation will increase dramatically because they are not being eaten .
Explanation:
hope this helps , sorry middle school was a long time ago for me : )
Answer and explanation: it would mean that there would be an increase of fish which is what seaguls eat but a decrease of, for example, leopard seals because if there aren't enough seagulls the leopard seals would die of starvation which would then again decrease another animal species because there aren't enough leopard seals. This would then repeat itself again and again.

During daylight savings, Christie's neighborhood soccer games get cut short because the sky becomes dark much earlier than during the summer. Her father talked to the electric company about installing large lights above the field so Christie and other kids in the community could continue their soccer games after dark. The electric company informed Christie's father that although the light poles could be installed, there are too many short trees and trees with low branches in the park to connect electrical lines. Without electricity delivered to the light poles, they would not work. Christie and her father talked about this information with neighborhood residents and together they came up with several ways to solve the problem.
Considering the concerns of everyone involved, which idea would be the BEST solution to the problem?
A)
Instead of electrical light poles, install solar-powered light poles.
B)
Parents can leave their cars running with headlights on facing the park.
Build several large fire pits around the field and light them each night.
D)
Cut down the larger trees, install the electrical lines, and replant the area
with shrubs.

BIOLOGY EXPERTS!!!! Shared core processes support the relatedness of all eukaryotes. Discuss how chromosome structure and function provides insights into the history of life on Earth.
Answer: Many eukaryotic organisms are related based on the shared core characteristics and processes.
Explanation:
The following are the shared core processes shared by all eukaryotes.:
1. Cytoskeleton: It is a network of structural proteins, that helps in movement of cell and organelle support.
2. Membrane-bound organelle: Mitochondria and chloroplast are organelles that formed via endosymbiosis these are present in all eukaryotic organisms.
The DNA is the basic genetic material that is found in almost majority of living beings on earth. The DNA is being transmitted from the primitive organisms on earth to the modern day organisms. The chromosomes are the carriers of DNA. These chromosomes are passed from the parents to the offsprings through reproduction. This is the basis of relatedness among organisms and these are also considered while studying the phylogenetic relationships.
Based on the information in the graph, explain what physical process causes the cell to change size.
Answer:
Osmosis
Explanation:
Osmosis is the process in which solvent molecules move from lower to higher concentration through a semipermeable membrane.
When a cell is placed in a hypertonic solution, the cell loses water and moves from higher concentration to lower concentration that is from inside the cell to the water solution and causes shrinking of cell.
Shrinking of cell means decrease in size of the cell along with the passing time and cell loses all its water.
Hence, the correct answer is osmosis.

Why is it important to monitor the pH and other factors in the AgWorks lab
Answer:
To know the actual pH for a particular organism.
Explanation:
It should be understood that in a 6,100-square-foot lab and classroom named AgWorks, students not only learn how to grow food in a controlled environment, but also explore and have the idea of agriculture-related careers.
In this aspect, the monitoring of pH is very important because not all organism survive in acidic and basic mediums, but there are some that required neutral medium for their survival. And this is the reason why to always affirm the particular pH necessary for the survival of a particular organism.
