Answer:
Sewage systems are used all around the world transferring waste to treatment plants where they are filtered and traded in for organic material. If the sluge were to be incinerated it could be repurposed, however the gas used to burn the sewage waste comes from condensing saturated fuel oil and requires 195 SCM of natural gas to successfully complete the chemical transfer. That's a lot of energy, and the natural process costs plenty more then what you're getting in returns. Through the process toxins can develop inside of the incinerated waste which could poison crops and animals, studies also show the process can release carbon monoxide into the air. To conclude it's called sewage waste for a reason, what goes down should stay down instead of putting what we eat and inhale at stake.
Hope this helps out! (ﾟヮﾟ) Sincerely, Kelsey from Brainly.

The incineration of sewage sludge may require more energy than it produces because of the high cost of energy.
Municipal wastewater treatment plants are estimated to consume more terawatt hours per year of electricity, which equates to about billions in annual electric costs. That's a lot of energy, and the results show that wastewater sludge able to produced up to 44.82 ml biogas/kg of sludgePeople may be reluctant to use bio solids as a fertilizer for food crops.
because:-
One health risk with the land application of bio solids is the potential exposure to pathogens (disease causing organisms)One of the risk is that the bio solids may contain chemicals that are directly toxic in small concentrations or doses.What is sewage sludge?Sewage sludge is a product of wastewater treatment.

Whales, humans, lizards, and birds each have forelimbs that are adapted for different functions, including swimming, using tools, walking, and flying. While different in function, these forelimbs share a similar skeletal structure of the humerus, radius, and ulna. How does a comparison of the forelimbs of these organisms provide evidence for evolution?
A. These homologous structures indicate that these four organisms all share a common ancestor.
B. These analogous structures indicate that whales are descended from organisms that lived on land.
C. These analogous structures indicate that these four organisms all experienced convergent evolution.
D. These homologous structures indicate that humans, whales, and birds all evolved from a lineage of lizards.
Answer:
A. These homologous structures indicate that these four organisms all share a common ancestor.
Explanation:
Homologous structures mean the organs will have similar structure, but not necessarily function (human arm vs whale's flipper). While analogous structures are similar in function but not structure (wings of an airplane vs wings of a bird). Since the question states that they are similar in skeletal structure, we know they must be homologous structures, thereby eliminating B and C. D is not a choice because the question does not provide anything about the order of evolution. Therefore the answer is A. These homologous structures indicate that these four organisms all share a common ancestor.

Explanation:
I'm sorry if it is wrong but I am almost 100% that it is correct!
Have a good one!
The solar flares and coronal mass ejections are caused by the sun's changing magnetic field. Also they are explosive events that can affect Earth. The correct options are C and D.
What is solar flare?A solar flare is a massive explosion on the Sun caused by the sudden release of energy stored in 'twisted' magnetic fields.
However, not all solar flares are safe. While the Earth's magnetic field protects us from solar radiation, the sheer electromagnetic power of a flare disrupts power grids, internet connections, and other communication devices.
Ejections occur at varying rates depending on the phase of the solar cycle, ranging from about 0.2 per day near the solar minimum to 3.5 per day near the solar maximum.
Coronal Mass Ejections are large plasma and magnetic field expulsions from the Sun's corona.
The sun's changing magnetic field causes solar flares and coronal mass ejections. They are also explosive events that can have an impact on Earth.
Thus, the correct options are C and D as per the given scenario.

A lake is home to a large number of trout. Identify what is most likely to happen if a chemical is dumped into the lake.
I. The trout will not be affected by the pollution.
II. The number of trout will increase.
III. The trout will suffer from disease.
A) I
B) I and II
C) III
D) II and III
Answer: C
Explanation: The process that occurred in the lake is natural selection. In the presence of an external environmental influence such as pollution, only the trouts that were fit to survive or in other words those that have the alleles that help in adapting to the new conditions live and increased in numbers. In such a case, one can say the fittest of the organisms survived and the corresponding allelic frequency in that population increased over time. The organisms carrying the other alleles died due to pollution and hence the overall frequency of alleles change.
A lake is home to a large number of trout the trout will suffer from disease is most likely to happen if a chemical is dumped into the lake. The correct option is C.
What is chemical pollution?Chemical pollution is the contamination of our environment with chemicals that are not naturally present.
According to scientific evidence, the trout in option will most likely suffer from disease.
Chemical pollution can harm aquatic life, including fish, by lowering oxygen levels, changing the pH balance of the water, and introducing toxins into their food chain.
Exposure to such chemicals can weaken the fish's immune system, making them more vulnerable to disease.
Option B and A is also less likely to be true because the introduction of chemicals into the water can disrupt the ecosystem's balance and affect the availability of food and oxygen, causing the trout population to decline.
Thus, the correct option is C.

Recent research investigating variation in human height has found that a variety of genes at different loci, as well as early nutrition, influence height, especially the nutrition of a mother during gestation (the period of time during development of a fetus) and of a child during childhood years,. Given this information, which of the following is correct? (3 points)
For human height, the environment is more influential than inheritance of particular alleles.
One phenotypic trait is usually related to one gene.
Phenotypes are directly linked to genotypes and not influenced externally.
Phenotypes are usually the result of a combination of genes and influence of the environment. I think is D
Answer:
It's the fourth one:
Phenotypes are usually the result of a combination of genes and influence of the environment.
Explanation:
Genes and the environment both affect phenotype.
Phenotypes are usually the result of a combination of genes and the influence of the environment.
What is genes?
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.
During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gene–environment interactions. Some genetic traits are instantly visible, such as eye color or the number of limbs, and some are not, such as blood type, the risk for specific diseases, or the thousands of basic biochemical processes that constitute life.
Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotypical traits. Usage of the term "having a gene" (e.g., "good genes," "hair color gene") typically refers to containing a different allele of the same, shared gene.Genes evolve due to natural selection / survival of the fittest and genetic drift of the alleles.

3. How would the bat population influence the number of cactus fruit that develop?
!!!!!!!!!!!!!!!!!!!!!!!!!
As the months pass, the table shows that the number of bats also causes an increase in the number of cactus flowers and fruit.
The cactus fruit don't seem to form in large number until the cactus flowers are also going up more in number. This is because pollination is necessary to form the fruit.
Based on this information:
The more bats in the population, the more pollination takes place, and the more cactus fruit is available as a result.
However, if the bats hit carrying capacity, they will be at a population number that is now bad for the number of cactus fruit, since there won't be enough food to feed the population- as more bats eat more fruit, the cactus isn't able to keep up with growing enough fruit to feed the bats at carrying capacity.

Answer: My theory was that they both were created at the same time. So if they both were created at the same time, then I guess that would solve this whole infinite loop thing. If the chicken came first, then it had to have come from an egg. So that means if the egg came first, where did that egg come from? A chicken. So its just a whole infinite loop. So thats what I think.
