When all of the populations live together in the same area, what is it called?
A. A community
B. A niche
C. An environment
D. An eco system
Answer:
When all of the populations live together in the same area, it is called:
A community
Why? Because a community occurs when multiple people are together, and the prefix com means "together".
By the way, I put in D on Edge, and it was wrong.When all type of the populaton lived together in the similar area so we called them as the community.
What is community?The population means the group of individual that are interbreeded with respect to the same species that should be isolated from the other group
while on the other hand, the community means the group or two or more various species that have the similar kind of geographical area.
Therefore, the option A is correct.

Answer:
An outbreak of a disease that infects squirrels in the park.
Explanation:
All the other answer choices would increase the population of squirrels. For the first option, more trees = more habitats = more squirrels to live in. For the second option, less hawks = less predators = more squirrels that will survive. For the third option, heavy rain = more acorns = more food for more squirrels.
Only the last option would limit the growth of a population of squirrels since diseases kill organisms in a population.

Bird species from temperate regions must cope with relatively short breeding seasons. A study examined the relationship between blood testosterone level (ng/ml) and the duration of the egg-laying period (months) in temperate bird species. The scatterplot below displays this relationship, after taking the logarithm of each variable. A plausible value for the correlation between the logarithm of egg-laying duration and the logarithm of testosterone level is
Answer:
The answer is "-0.4".
Explanation:
In that situation, the value of the possible correlations between the egg-laying logarithm as well as the testosterone level logarithm is equal to 4 It value is equal to the percentage 4=-0.4.

Which greenhouse gas is produced by commercial refrigeration and air conditioning systems?
carbon dioxide
fluorinated gas
nitrous oxide
methane
answer:
-- b), fluorinated gas
hope this helps.
The greenhouse gas that is produced by commercial refrigeration and air conditioning systems is fluorinated gas.
WHAT IS GREENHOUSE GAS?A greenhouse gas is a gas that has the ability to trap and release heat energy into the atmosphere.
Greenhouse gases are the major causes of global warming, which is the rise in the global atmospheric temperature.
Examples of greenhouse gases are carbon dioxide, methane, fluorinated gas etc. Therefore, greenhouse gas that is produced by commercial refrigeration and air conditioning systems is fluorinated gas.

Explain how one body system not functioning properly can affect another body
system.
Answer with explanation:
If a body system does not work properly then the other body systems will also fail because every system is needed for a person to live properly. For example if the respiratory system does not work properly then the other systems will be harmed as oxygen will not be able to move to other parts of the body. As a result, the kidneys will fail and the heart will stop working and the person will die.
One body system that is not functioning properly can affect another body system because, in an organism, coordination is maintained by the different organ systems. If one system is affected, then others will be too.
How is the body's system functioning?In a multicellular organism, the organism is regulated by the coordination of the different organ systems, such as the circulatory system, digestive system, etc. In the human body, many systems are present, and each system is made up of many organs. In the nervous system, the nerves, brain, and spinal cord are involved, in the circulatory system, the blood, blood vessels, heart, and lungs are involved, and the lungs are involved in the respiratory system too. Because a single organ is involved in multiple organ systems, if one system is affected, the others will be affected as well.
Hence, one body system that is not functioning properly can affect another body system because, in an organism, coordination is maintained by the different organ systems.

Explanation:
Describe the probable effects on gene expression in the lac operon of each mutation: a. Mutation in the lac operator that deletes most of O1 b. Mutation in the lacI gene that eliminates binding of repressor to operator c. Mutation in the promoter near position
Answer:
a. Reduces represor binding.
b. Constitutive expression of the operon.
c. Stronger promoter if it is more similar to the consensus sequence. Weaker promoter if less similar.
Explanation:
The lac operon is an operon required for lactose transport and metabolism in enteric bacteria such as Escherichia coli. It is regulated by glucose and lactose availability and consists of the following structural genes:
Lac z gene: encodes the enzyme β-galactosidase, which catalyzes the hydrolysis reaction of lactose into glucose and galactose.Gene lac y: encodes the protein galactoside permease involved in the transport of lactose into the bacterium.Lac a gene: encodes the enzyme thiogalactoside transferase, which catalyzes the transfer of the acetyl group of acetyl coenzyme A to 6-OH of a thiogalactoside acceptor. This gene is not related to lactose metabolism.Promoter: region of DNA recognized by RNA polymerase for transcription.Operator: region of DNA located between the promoter and the beginning of the structural genes, which is recognized by the repressor protein Lac I.Repressor gene (lac I): encodes the Lac I repressor protein, which recognizes the operator region, where it binds. It prevents the transcription of genes under the control of this promoter but stimulates the binding of RNA polymerase. When the repressor is absent (in the presence of inducer which in this case will be lactose or IPTG), RNA polymerase will begin transcription.The lac operon is under a type of negative regulation, where genes can always be transcribed, except when the Lac I repressor protein is bound to the operon region, for which it has a high affinity. In this case, the promoter of the lac I gene is constitutive, so the Lac I protein is permanently expressed and remains bound in tetramer form to the operon region, preventing the transcription of structural genes.
Since lactose is the inducer of the operon, it is able to bind to the Lac I repressor protein and generate a conformational change that decreases its affinity for the operon region. Thus, the operon region is left free, RNA polymerase can freely transcribe the structural genes and β-galactosidase can degrade lactose to glucose plus galactose. In the absence of lactose, the Lac I repressor protein maintains its high affinity for the operator region, preventing RNA polymerase from transcribing the structural genes. In this way, the system remains closed with consequent energy savings for the bacterium.
As a final clarification, actually the true inducing molecule of the lac operon is called allolactose, an isomer of lactose obtained by a transglycosylation occasionally carried out by β-galactosidase.
a. When there is a mutation in the lac operator that deletes most of the operator, then the repressor Lac I can no longer bind and RNA polymerase will begin transcription.
b. When there is a mutation in the Lac I gene that eliminates the binding of repressor to operator, then this protein can not produce the repression so there would be a constitutive expression of the operon.
c. Since the promoter us a region of DNA recognized by RNA polymerase for transcription, if there is a mutation here it will generate a stronger promoter in the case that this part is similar to a consensus sequence (the most commonly encountered nucleotides found at a certain location). In the case that it is less similar, then it will generate a weaker promoter.
