How does the nitrogen cycle control the quality of water within a aquarium and what could cause an imbalance (build of toxic chemicals such as ammonium).
Answer:
Explanation:
Ammonia is removed from an aquarium system through the use of a biofilter. The biofilter provides a substrate on which nitrifying bacteria grow. These nitrifying bacteria consume ammonia and produce nitrite, which is also toxic to fish. Other nitrifying bacteria in the biofilter consume nitrite and produce nitrate.

Which is considered a chemical mutagen?
Answer:
The chemicals which help in imposing heritable changes in the genotype of an organism are termed as "Chemical Mutagens". "Hydroxylamine" (NH₂OH) and "Nitrous acid" (HNO₂) are chemical mutagens.
Explanation:
these types of leaves have one main vein called the midrib , and smaller branching vein
stomate
crenate
lobed
parted
The leaf has 2 types of venation the parallel venation and reticulate venation.
All of the veins, the petiole, and the midrib help position the blade so that it is facing the light source.
9. Why is it not reasonable to think that all variables can be controlled?
I
Answer:
Any given experiment has numerous control variables, and it's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variables.
Explanation:
similarities between renal atery and renal vein
Answer:
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
Explanation:
Match the method of predator management to the challenges It faces. 1. use of firearms considered inhumane 2. use of poisons revised laws 3. use of traps inefficient and dangerous
Answer:
question
Explanation:
did you ever figure out what the answer was? please
Answer:
use of firearms- revised laws
use of posions -inefficient and dangerous
use fo traps- considered inhumane
Explanation:
Option 1 faces a challenge of revised laws. Although use of firearms was once a popular method of control, changes to laws, in particular those pertaining to wolves, have affected the issue. Option 2 faces a challenge of being inefficient and dangerous. Poison is illegal, largely because it is an inefficient practice that can be dangerous to both cattle and nonpredatory wild animals. Option 3 faces a challenge of being considered inhumane. The use of traps is an indiscriminate tool, like poison, often trapping the calves they are intended to protect.

How many steps are involved in the bioremediation process?
What is the energy input to the radiometer system? What form(s) of energy are present in the system as a result?
Answer:
What happens to the work done on a system? Energy is transferred into the system, but in what form? Does it remain in the system or move on? The answers depend on the situation. For example, if the lawn mower in Figure 1a is pushed just hard enough to keep it going at a constant speed, then energy put into the mower by the person is removed continuously by friction, and eventually leaves the system in the form of heat transfer.

Answer:
synovial
Explanation:
A synovial bursa (plural bursae or bursas) is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of viscous synovial fluid (similar in consistency to that of a raw egg white). It provides a cushion between bones and tendons and/or muscles around a joint.
Which best describes the process that occurs when nuclear DNA codes for a protein in the cytoplasm
Answer:
Transcription is the process
Translation is the process that occurs when nuclear DNA codes for a protein in the cytoplasm.
How DNA is translated into protein?Transcription is defined as a process where DNA is transcribed into mRNA. Translation occurs in the cytoplasm inside the ribosomes where mRNA is translated and synthesized into a protein with the help of rRNA and tRNA.
DNA is the genetic material, which is transcribed into mRNA, this process copies the DNA into another nucleotide sequence, and this messenger RNA is passed into the nucleus, where it translates.
In the cytoplasm, mRNA is translated into the amino acid sequence with the help of ribosome and tRNA.
Therefore, translation best describes the process that occurs when nuclear DNA codes for a protein in the cytoplasm.

Choose the mutation that you think is causing Lucy’s ADA enzyme not to work. Form a hypothesis and explain your answer. You can revise your hypothesis as you perform more experiments.
answer
stop condon mutation
Explanation:
The mutation is defined as the alteration or change in the genetic sequence of the chromosome. The mutations in the ADA genes have been noted and are caused by point mutations.
Point mutations are defined as the mutations in which the alteration of the single nucleotide of DNA occurs.
Stop codon mutations are the type of point mutations, in which the nonsense codons signal the end of protein synthesis.
Adenosine deaminase is involved in purine metabolism. It is involved in the development of the immune system.
Lucy's condition is due to the stop codon mutations in the genetic sequence of the DNA. The stop codon mutation will signal the end of the translation process, which will result in the non-functionality of the ADA enzyme.
Therefore, the stop codon mutation in the ADA enzyme will occur in Lucy's genetic sequence.

What would happen to a cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute?
A cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute - cell will lose water and shrink.
A hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic
if you place a cell in a hypertonic solution, the cell shrinksit loses water as due to osmosis water moves from a higher concentration inside the cell to a lower concentration outsideThe water will move out of the cell to try to equalize.Thus, A cell if its cytoplasm contains 97% water and 3% solute and it is placed into a container that has a solution of 92% water and 8% solute - cell will lose water and shrink.
