What is happening within the moon jelly population when the size of the moon jelly population is stable.
Answer:
The jelly is able to hold the weight of gravity
Explanation:
To reproduce, organisms need to release energy from energy storage molecules. If there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births. Fewer deaths would also cause the jelly population to increase.
What are moon jellies made of?The moon jelly is one of the most common jellyfish in Rhode Island. Its body shape resembles an umbrella, with four equal-sized horseshoe-shaped gonads in the center of its body. Moon jellies are made up almost entirely of water and will not hold their shape when out of the water.

When is the lac operon most active?
A. When glucose levels are high and lactose is present
B. When glucose levels are low and lactose is absent
C. When glucose levels are low and lactose is present
D. When glucose levels are high and lactose is absent
Answer: The correct answer to the question is option WHEN GLUCOSE LEVELS ARE LOW AND LACTOSE IS PRESENT.
Explanation: To start with,Lac operon can be simply defined as a part of the DNA that is under the part of the DNA is manipulated and controlled by the same promoter,they can be found in some prokaryotic cells giving room for regulation over excess synthesis of protein.so simply put,these specific segment of the DNA binds with the segment of the polymerase of RNA so that transcription of the mRNA from the operon genes will be achieved.
Lac operon is also known as lactose operon, it is seen in some enteric bacteria like e.coli where they play a crucial role in coding of genes for those proteins that function in moving lactose into the cystocel and digesting it to form glucose that is used for energy generation. These lac operon are are most active when glucose levels are low and lactose is present,with the low level of glucose, the lac operon can be transcribed to a high level,this is to ascertain that the bacteria only gets to activate the lac operon and can only make use of it,that is using lactose when all the preferred energy source from glucose has been exhausted.

The expansion of the ranges of tropical fish was most likely caused by-
A. agricultural runoff that contributes to dead zones in the ocean
B.global droughts that raise the salt concentration of ocean waters
C.the rising temperatures of ocean waters
D.acid rain pollution that lowers the pH of ocean water
Answer:
C
Explanation:
The expansion of the ranges of these fish was most likely caused by the rising temperatures of ocean waters. This is because these types of fishes live in both fresh-water and salt-water but only in aquatic tropical environments around the world. The increase in temperatures of ocean waters has provided more suitable habitats for these fishes to expand to.

Why doesn’t urine flow back to the ureters?
Answer:
With vesicoureteral reflux, urine flows backward from the bladder, up the ureter to the kidney. It may happen in one or both ureters. When the "flap valve" doesn't work and lets urine flow backward, bacteria from the bladder can enter the kidney. This may cause a kidney infection that can cause kidney damage.
Identify and describe the three ways that mutation affect organisms
Answer:
they may cause the development of a disease-causing allele
they may cause the development of a more beneficial allele
they in some cases, may have no noticeable affect
Explanation:
Answer:
Sample Response: Mutations may be beneficial, harmful, or neutral to organisms. If the change caused by a mutation is useful to the organism, then it is beneficial. If the change is damaging to an organism, then it is harmful. If the change is neither useful nor damaging, then the mutation is neutral.

What's the capstone project?
is it important?
Answer:
A capstone course, also known as capstone unit or a senior thesis or senior seminar serves as the culminating and usually integrative experience of an educational programtion A capstone project plays a vital role in preparing a student for the future course of learning. It gives students a chance to retain whatever they have been learning during their college studies and apply it once they pursue a specific academic profession in the college.
A capstone project is a culminating academic undertaking that often marks the final contribution or achievement in a student's academic career. It is often undertaken in the final year of a programme, such as a bachelor's or master's degree. The importance of a capstone project can be significant for several reasons:
Integration of KnowledgePreparation for the WorkforcePortfolio PieceAssessment of Learning OutcomesThe details of the capstone project vary according to program requirements, institution and subject of study. A capstone project's ability to integrate and apply the knowledge, abilities and concepts acquired during the academic program determines its importance. It gives students the chance to demonstrate their understanding, critical thinking, problem-solving and research skills in a practical setting. Research, data analysis, problem-solving, and the creation of useful results or products are often components of capstone projects.

The correct answers are:
A treeA flowerA bacteriumA fishWhy organisms need sunlight?All of these organisms can have all of the energy they use to move, grow, and survive traced back to radiant energy from the Sun. Trees and flowers undergo photosynthesis to convert sunlight into energy in the form of glucose, which they use to grow and carry out metabolic processes.
Bacteria can also undergo photosynthesis, or they can use organic matter as a source of energy, which ultimately comes from the Sun through the food chain. Fish, as well as other animals, obtain their energy by consuming other organisms that have obtained energy from the Sun through photosynthesis or other means.
Humans are also ultimately dependent on the Sun's energy, but they obtain their energy indirectly through the food they consume, rather than directly from photosynthesis.

Computer simulation is becoming a commonly used process to efficiently model and evaluate the impact of a variety of proposed solutions when facing a complex real-world problem. Reasons for using computer simulation over actual production of possible solutions include all except:
A) costs associated with testing and prototyping too high
B) computers are not as trustworthy as actual prototypes are
C) trial system would not withstand significant testing desired
D) time necessary to acquire and analyze results prohibitively long
Answer:
The correct answer is option B) "computers are not as trustworthy as actual prototypes are"
Explanation:
It is false to affirm that results obtained from computer simulations towards looking for solutions of real-world problems are not as trustworthy as results obtained from actual prototypes. In most cases, computer simulations had proved to be reliable, particularly when the programers use validating arithmetic and algorithms. There are multiple companies dedicated to develop computer simulations to solve real-world problems, which are constantly used and tested in scientific investigations.
