Sewage sludge (biosolids) removed from a municipal wastewater treatment plant is a mixture of organic material and water. Research and explain why the incineration of sewage sludge may require more energy than it produces. Explain why people may be reluctant to use biosolids as a fertilizer for food crops.
Hey love! <3
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.

Will genes that are 16 map units apart recombine more or less frequently than genes that are 15 map units apart?
Group of answer choices:
a. less
b. more
c. could be more or less, depending on the frequency of double crossovers
d. it is impossible to know
e. the same
The correct option is c. could be more or less, depending on the frequency of double crossovers
How does genetic recombination vary with gene distance?The frequency of recombination between two genes that are 16 map units apart could be more or less than genes that are 15 map units apart. This is because the distance between genes on a chromosome does not directly determine the frequency of recombination.
Recombination frequency is influenced by various factors, including the presence of recombination hotspots, the physical structure of the chromosome, and the likelihood of double crossovers occurring.
Double crossovers, where two crossovers happen between the same two genes, can affect the accuracy of pping distances. If double crossovers are more likely to occur in the region between the 16 map unit genes, the actual recombination frequency may be higher than expected. The recombination frequency can vary and is not solely determined by the distance between genes.
Therefore, The correct option is c. could be more or less, depending on the frequency of double crossovers.

how come human populations differ from other animal populations
Answer:
Animal species come in many shapes and sizes, as do the individuals and populations that make up each species. To us, humans might seem to show particularly high levels of morphological variation, but perhaps this perception is simply based on enhanced recognition of individual conspecifics relative to individual heterospecifics. We here more objectively ask how humans compare to other animals ...

What is transcription?
The first step before protein arrangement is to synthesize messenger RNA, mRNA.
Transcription is the synthesis of the messenger RNA, mRNA. This event occurs in the nucleus and uses fragments of DNA molecules to do it.
When the DNI molecule separates into two strands, we can identify
The coding strand –non-template strand- goes in direction 5' to 3',The complementary strand -template strand- grows in direction 3' to 5'.The template strand is the one that is going to be complemented by the mRNA.
mRNA molecule grows complementing DNA base sequences. This is,
DNA mRNA
adenine ⇔ uracil
guanine ⇔ cytosine
thymine ⇔ adenine
cytosine ⇔ guanine
Once mRNA synthesis is over, the molecule leaves the nucleus to start the transcription process in the cytoplasm.

A gene with the sequence ATTCATTCA underwent duplication after a few generations. Which sequence represents this gene after the mutation?
Answer:
The sequence would be ATTCATTCA.
Explanation:
Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.
So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files.

which of the following describes a cytotoxic autoimmune reaction? group of answer choices immune complexes form. antibodies react to cell-surface antigens. it is mediated by t-cells. antibodies are not made. cells are killed.
A cytotoxic autoimmune reaction is described as "cells are killed."
The immune system protects the body from external agents that can cause harm by targeting and removing them.
The immune system's function is to recognize foreign organisms and molecules, such as bacteria, viruses, fungi, and toxins, and respond to them by producing an immune response or immunologic memory.
A cytotoxic autoimmune response is a type of autoimmune response. The immune system mistakenly attacks and kills the body's cells in this reaction.
This condition causes an inflammatory reaction, which can cause tissue damage and a variety of symptoms. It may lead to the destruction of healthy cells if the immune system perceives them as foreign or dangerous.
As a result, the immune system's T-cells and antibodies attack the body's own cells.

What is chlorarachniophytes ?A minor subclass of marine algae found in both tropical and arctic waters, the chlorarachniophytes. Typically mixotrophic, they carry out photosynthesis in addition to eating bacteria and tiny protists. The majority of the time, they resemble little amoebas and have branching cytoplasmic extensions that catch prey and join the cells to form a net. They can also produce walled coccoid cells and flagellate zoospores, which are characterized by a single subapical flagellum that loops around the cell body.
Taking in some green algae is probably how the chloroplasts were obtained. They are encircled by four membranes, the outermost of which is continuous with the endoplasmic reticulum. A little nucleomorph, which is a piece of the alga's nucleus, is located between the middle two membranes.

They are believed to represent the remains of early red and green algal nuclei that were swallowed by a more advanced eukaryote. The nucleomorph supports the endosymbiotic idea and is proof that the plastids containing it are complex plastids because it is sandwiched between two sets of membranes. The plastid is an example of secondary endosymbiosis since it has two sets of membranes, indicating that it was a prokaryote that was engulfed by a eukaryote, which was then engulfed by the host cell, an additional eukaryote.
