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 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.

Which venn diagram accurately describes what characteristics of solids, liquids, and gasses could be added to this diagram
Answer:
See explanation for image
Explanation:
The Venn diagram that can accurately show the characteristics of solids, liquids, and gases, can show which characteristics are unique to each of these states of matter and which characteristics are shared among the three.
You did not present the answer options, but it was possible to find them in questions like yours. These answer options are in the figure attached below and among them, the letter B is the correct answer.
Regarding the Venn diagram, we can say that:
The diagram consists of three circles, which overlap, sharing a small space, in the center of the three.Each circle represents a different element.The part of the circle that is away from the shared center refers to the particular characteristics of each element.The part of the circle that is within the shared center refers to the characteristics shared between these elements.In diagram B shown in the figure below, it meets all the requirements shown above.
In this diagram, the shared center presents the common characteristics of solids, liquids, and gases. However, the top circle shows the particular characteristics of solids. The circle on the left shows the particular characteristics of gases, while the circle on the right shows the particular characteristics of liquids.

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.

Answer:
vaccines inject either weaker strain or dead viruses into the body in order for the immune system to produce antibodies that will help fight off the disease in the future.
hope this helps

Explanation:
emphysema and asthma are respiratory disorders that may both be attributed to smoking; they also share many symptoms in common. As a physician, how would you distinguish between these two disorders when diagnosing a patient? explain.
Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged. Chronic bronchitis is when the tubes that carry air to your lungs (bronchial tubes) get inflamed. Smoking is the most common cause of those conditions (and COPD).
Some people have asthma and COPD at the same time. If you have symptoms of both diseases, your doctor may call it asthma-COPD overlap syndrome.
People who smoke or breathe in pollution or chemicals at work for many years have higher chances of having COPD. That's why the condition often starts in middle age or later in life.
Asthma is sometimes caused by gene changes that are passed down through families. If one of your parents has the disease, you're more likely to have it. Symptoms often start in childhood.
Since asthma and COPD both make your airways swell, they both can cause shortness of breath,coughing, and wheezing.
One main difference is that asthma typically causes attacks of wheezing and tightness in your chest. COPD symptoms are usually more constant and can include a nasty cough.
To figure out which condition you have, your doctor will start with a physical exam and questions about your medical history. They’ll look at your nose and throat and listen to your lungs with a stethoscope. Your doctor will also want to do a test called Spirometry that checks how well your lungs work.

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.
