Explain how the speed of light changes between a gas liquid and solid
Answer:
As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.

A sugar farm near the coast of Florida applies a nitrogen based fertilizer to their soil three times a year. When rain falls on these fields after it has been fertilized some of the fertilizer runs off into the ocean causing the nitrogen levels in the water to increase. The increase levels of nitrogen can lead to many ecological effects beginning with the rapid growth of algae. This process is known as eutrophication.
How can eutrophication affect other organisms in the water?
Group of answer choices
The algae provide food for fishes and other organisms, leading to decreased algae populations.
The oxygen in the water is used up as algae is decomposed, reducing the amount available to other organisms.
The water becomes better able to support aerobic organisms.
The extra nitrogen provides additional food for the other organisms, increasing their population.
Answer:
The algae provide food for fishes and other organisms, leading to decreased algae populations
Explanation:
Excessive nutrients lead to algal blooms and low-oxygen (hypoxic) waters that can kill fish and seagrass and reduce essential fish habitats. ... Eutrophication sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants.

plz help asap! The activity of many cellular enzymes is regulated by activators and inhibitors. Enzyme activity is also regulated in eukaryotic cells by which of the following mechanisms?
Compartmentalization and restricting enzymes to specific organelles or membranes
Secreting enzymes out of the cell
Limiting the availability of substrates
Changing the primary structure of enzymes
Answer:
compartmentalization and restricting enzymes to specific organelles or membranes
Cellular steroid gradients are produced by the compartmentalization of enzymes into various organelles of a cell, and this might impact how well the various steroid products are balanced. Thus, option A is correct.
What is Compartmentalization?In biology, the biomembrane, or biological membrane, effectively compartmentalizes enzymes by allowing them to perform only certain functions within a limited area.
The enzymes may be located on the membrane surface or inside the defined compartments.
A percentage of the enzymes would likely not work or their ability to catalyze reactions would likely be insufficient if there was just one cellular compartment.
This is because enzymes catalyzing distinct reactions frequently have variable temperature and pH optimums.
Therefore, Compartmentalization and restricting enzymes to specific organelles or membranes.

why is oxygen important in aerobic respiration
Answer:
Oxygen is the final electron acceptor at the end of the electron transport chain of aerobic respiration. In the absence of oxygen, only a few ATP are produced from glucose. In the presence of oxygen, many more ATP are made.
Answer:
Oxygen is the final electron acceptor therefor its very important
Explanation:
The final stage of aerobic respiration which involves oxygen makes the most ATP since i believe it makes 32 ATP. Therefor its very important
Bacteria belong to the domain Bacteria. Which characteristic is used to classify these organisms as Bacteria?
Bacteria are heterotrophs.
Bacteria are multicellular.
Bacteria are prokaryotes.
Bacteria cells contain a nucleus.
Answer:
Bacteria are prokaryotes
Answer:
Bacteria are prokaryotes
Explanation:
What is a prokaryote?
a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria. Compare with eukaryote.Read the paragraph from the section "Pea Plants And The Punnett Square."
A pea plant could have one copy of the height gene that coded for "tall" and one copy of the height gene that coded for
"short." The tall allele is "dominant," and this means that it can mask the other allele. The short allele is called
"recessive." The allele combination of tall-short would result in a tall plant since the tall allele is dominant.
Which option is the BEST definition of the word "mask" as used in the paragraph above?
A pea plant could have one copy of the height gene that coded for “tall” and one copy of the height gene that coded for “short”. The tall allele is “dominant”, and this means that it can mask the other allele.

If the amount if algae in the ocean decreases by 50% the population of its consumers, goby fish will?
A. Go extinct
B. Decrease to its carrying capacity
C. Increase by 50%
D. Increase to its carrying capacity
Answer:
B. Decrease to its carrying capacity
Explanation:
Goby fish feed over algae for their survival and growth but if 50% of algae in the ocean decreases then the population of goby fish will decrease to its carrying capacity.
This is so because then the goby fish will be dependent on the left number of algae and maximum population size will depend on the rest 50% of food or algae available.
Hence, the correct answer is "B. Decrease to its carrying capacity".

A population of sea urchins in a kelp forest ecosystem is being over-fished. A team of students believe that a decline in the number of sea urchins will affect the organisms in the kelp forest ecosystem. The kelp forest food web below shows the relationships among the organisms in the kelp forest ecosystem.
Answer:
Explanation:
This response shows some understanding of the question. The ecological relationships among the otter, crab, and urchin are addressed in a very general manner (kelp crabs and sea urchins feed off of kelp, only to be eaten by the sea otter). In a further explanation, the student overstates the effect of a decrease in the populations of the organisms. (The sea urchin and crab won't get the food from the kelp and die off. The otter will starve and die off too.) The supporting details are minimally effective.
Which of the following is NOT a reaction of the
parasympathetic nervous system?
A. Decreased respiration
B. Decreased heart rate
C. Increased blood flow to digestive tract
D. Decreased saliva production
Answer:
D
Explanation:
D, or decreased saliva production is not a reaction of the parasympathetic nervous system (PSNS) since the PSNS actually increases/causes salivation which helps you digest your food.
As a tip, I usually associate the PSNS with a state of rest/restful conditions, as opposed to the sympathetic nervous system which is the opposite and is associated with stress and high-pressure conditions (like fight or flight).

Which statement applies to transverse waves?
The waves have a trough.
Particles move great distances.
The waves have alternating compressions and expansions.
The energy is transferred parallel to the direction of the wave motion.
Answer:
A) The waves have trough
Explanation:
100% sure
The statement 'the waves have a trough' applies to transverse waves.
What are transverse waves?Transverse waves are a type of wave in which their fluctuations need to be perpendicular to the wave.
Conversely, longitudinal waves are waves in which their oscillations have the same direction of the wave.A wave can be defined as any type of disturbance capable of carrying energy but that does not involve motion.In conclusion, the statement 'the waves have a trough' applies to transverse waves.
