Do you think water pollution has a greater effect on humans than air pollution?
Answer:
I think they are both as bad.
Explanation:
I say this because air pollution can cause water pollution but the same goes the other way around.
Answer:
No, air pollution is worse.
Explanation:
Whilst water pollution would kill s over time from dehydration, the air pollution would kill us first. Air is how we breathe and that would kill us before the water did. Over all, air pollution would kill us first.
Explain the role that sponges have in the environment
Answer:
Sponges collect bacteria when they filter the water around them. ... They may also be able to turn ammonium from the sponge's breathing into nitrogen gas that is then released into the atmosphere. This process would lower excess nitrogen levels in coral reefs, also preventing harmful ecosystem changes.
Explanation:
Answer: sponges have a role in the environment because they suck up the water or liquid.

Dolphins chasing and eating fish would be an example of what type of relationship?
Group of answer choices
Predation
Competition
Mutualism
Parasitism
Answer:
predation, because it is a predator and prey
Explanation:
Dolphins chasing and eating fish would be an example of a predation relationship. This is because dolphins are the predator of all such small fishes which are living simultaneously.
What do you mean by Predators?Predators may be defined as the organisms that hunt or kill other organisms, particularly for food.
Predation is a type of interaction where one species is benefitted in the presence of another species, while the other species is harmed or lost in the presence of the first species.
Therefore, dolphins and other fishes show predation interaction.

Consider a hypothetical scenario in which the genes that determine body color, eye color, and wing type in fruit flies occur on the same chromosome. To determine the order of the three genes on the chromosome, a researcher looks at hundreds of flies and makes these observations: 90% of flies with red eyes have curly wings. 75% of flies with red eyes have black bodies, whereas the remaining 25% have brown bodies. 1% of flies have curly wings, white eyes, and black bodies. Based on these observations, what is the most probable location of each gene on the given chromosome
Answer:
The most probable location on the chromosome of each gene is:
wing shape gene ------- eye color gene -------- body color gene
Explanation:
To know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.
We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent. And simple recombinant gametes produced by the cross, which frequencies are intermediate.
By comparing the parental and the double recombinant we will realize which is the allele that changes in position. The position of this gene is in the middle of the other two genes because in a double recombinant only the central gene changes position in the chromatid.
So, according to this knowledge and the available information in the problem we can estimate the position of the genes in the chromosome.
Phenotypic proportions:
90% of flies with red eyes have curly wings (Parental)75% of flies with red eyes have black bodies (Simple recombinant)25% of flies with red eyes have brown bodies (Simple recombinant)1% of flies have curly wings, white eyes, and black bodies (Double recombinant)90% of individuals are red-eyed and curly-winged. This is a high frequency, which means that this is the parental phenotype. The other parental phenotype must be white eyes and straight wings.
Flies with curly wings, white eyes, and black bodies represent the lower proportion (1%) so this phenotype must be the double recombinant.
Flies with red eyes and black bodies, and flyes with red eyes and brown bodies are intermediate in proportion, so they must be simple recombinant phenotypes.
Parental)
Red, Curly
White, Straight
Double recombinant)
White, Curly, Black
Red, Straight, Brown
Simple recombinant)
Red, Black
Red, Brown
In the chromatid, there are two regions, Region 1 (from the first gene to the gene in the middle), and region 2 (from the gene in the middle to the gene of the other extreme).
The fact that both simple recombinants are red, tells us that the eye color gene and the body color gene are together, and the recombination occurred either in region 1 or 2.
We know that the double recombinant is White, Curly, Black. We also know that the eye color gene and the body color gene are together, so one of these two must be in the middle.
Parentals are red and curly, which means that the eye color gene and wing shape gene are also together. This leads us to assume that the eye color gene is in the middle.
Finally, the fact that the double recombinant is White, Curly, Black, and knowing that the eye color is in the middle and that both the extreme alleles change position, we can assume that the parental Red, Curly is also black, while the other parental is white, straight and brown. So:
Parental)Curly ------ Red ------Black (90%)
Straight ----- White ----- Brown
Simple recombinant)Curly -----White-----Brown
Straight-----Red -----Black (75%)
Curly----Red-----Brown (25%)
Straight ----White-----Black
Double recombinant)Curly-----White------Black (1%)
Straight----Red------Brown

Both photosynthesis and cellular respiration are part of the carbon cycle. Which statement best compares these two processes? Both release carbon dioxide as waste. Both provide organisms with usable energy. Both add bacteria to the soil. Both require fixation in order to convert molecules.
Answer:
Both provide organisms with usable energy.
Explanation:
Both photosynthesis and cellular respiration, a component of the carbon cycle provides an organism with usable energy.
Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water using sunlight to produce energy rich glucose and oxygen gas as a by-product.
During cellular respiration is an oxygen driven aerobic process in which organisms breaks down glucose to produce energy rich ATP.
Both processes furnishes an organism with energy in the end. Although, photosynthesis is an energy building process, cellular respiration breaks down materials to liberate energy. This energy is used by both plants and animals for their living activities.Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

Aquarium salt water is prepared to a salinity of 30 ppt (parts per trillion) by dissolving 3.26 kg of salt into 114 L of water. If you wanted to make 4,000 mL of salt water at the same salinity, how many grams of salt will you need?
Answer:
114 gram of salt is required.
Explanation:
Below are the following given data in the question:
Prepared salinity water = 30 ppt
Weight of salt used = 3.26 kg
The volume of water = 114 L
Below is the calculation.
4000 mL = 4000/1000 = 4L
Let the used = x kg
3.26/114 = x/4L
Now solve for the x.
x = 0.114 kg or 114 gram
