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.

Describe the 3 ways plant seeds are dispered by other organisms. *
Answer:
Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.

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.

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.

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.
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.

Even though mitosis and meiosis produce cells for different purposes, there are similarities
between the two processes. Which statement most accurately states how the two types of cell
division are alike?
Sister chromatids separate during anaphase II and mitotic anaphase is the statement most accurately states how the two types of cell division are alike. Hence, option D is correct.
What is Sister chromatids?Each chromosome is made up of two full-length DNA molecules joined at the centromere after DNA replication as part of cell division. They are two distinct DNA molecules known as sister chromatids.
Sister chromatids are two identical copies of the same chromosome that are produced by DNA replication and joined by a structure known as the centromere. They are divided during cell division, with one copy of each chromosome going to each daughter cell.
A chromatid is one of the two identical halves of a chromosome that has undergone replication ahead of cell division. The two "sister" chromatids are connected at the centromere, a constricted region of the chromosome.
Thus, option D is correct.

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.
