Glycolysis, or the breakdown of glucose, is a process used by almost all organisms as a way to release energy stored within glucose molecules. This energy can then be stored in cells as ATP, which powers cell processes when needed. What does this show, in terms of the evolutionary history of cells using glycolysis?
Answer:
It was one of the earliest metabolic pathways.
Explanation:
The evolutionary history of cells using glycolysis shows that It was one of the earliest metabolic pathways which is used by nearly all of the organisms on earth for the production of energy for the survival, growth and development. The first organisms used this pathway for the generation of energy and with the passage of time, new pathways are also formed as the organism evolved so we can conclude that glycolysis is the first pathway used by the earliest organisms.
what happens when there is a decrease in carbon dioxide during gas exchange in the body?
Answer:
Increased carbon dioxide means increased blood acidity, while decreased carbon dioxide means increased blood acidity.
The bicarbonate reaction is reversible, which allows bicarbonate to turn back into dissolved carbon dioxide to diffuse from the alveolus.

A red frog and a blue frog mate and have offspring. If the gene is Codominant, what will be the color of their offspring?
Answer:
The correct answer is - blue and red both.
Explanation:
Codominance is the type of inheritance pattern in which alleles interact differently with one other. In this type of inheritance, neither allele is dominant or recessive and both traits are visible in the progeny if both alleles are present together in heterozygous conditions.
Here, in this case, Red frog and the blue frog are in codominance so the cross of these frogs leads to both colors that will be express in offspring together.

1. What is the gradual change in populations over time?
2. What is the idea that species originate in small gradual steps over time?
1. Gradualism
2. evolution
Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.
2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).
Explanation:
The organization of similar organisms into groups helps scientists understand how living things are related. It
also allows scientists to communicate about all forms of life. Scientists organize the living world using a process
called taxonomy, which is the science of classifying organisms based on shared structures, functions, and
relationships to other organisms. Scientists use a branching system of classification, and over the years, due to
new discoveries, the branching system has changed and grown.
Recently, scientists broadened the branching system of classification. Currently, the broadest group is the

When wood combines with oxygen and burns, ashes and carbon dioxide are produced. How does the Law of Conservation of Matter relate to this observation?
A. The mass of the wood will be destroyed.
B. The weight of these substances will change but the mass will stay the same.
C. The mass of each of these substances will be the same before and after the reaction.
D. The mass of the wood and the oxygen burned will equal the mass of the ashes and the carbon dioxide produced during the reaction.
Answer:
Option C
Explanation:
Conservation of matter states that matter can not be created nor it can be destroyed. It can only be changed from one form to the other.
In this case, the matter contained is wood (solid) is converted into ash (solid) and carbon dioxide (gas).
The amount of all substances remains constant irrespective of any condition during a chemical reaction
Hence, option C is correct
The initial step in the formation of an aminoacyl-tRNA is Group of answer choices esterification of the tRNA activation of the tRNA by reaction with ATP activation of the amino acid by reaction with ATP interaction of the mRNA with the tRNA
Answer:
The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP
Explanation:
In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.
The first step of the reaction of the formation of an aminoacyl-tRNA is the activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.
The overall reaction step is illustrated below:
Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi

Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species because of differences in color patterns of the feathers and size of the beak. Recently these birds have been reclassified as eastern and western forms of a single species, the yellow-rumped warbler, based on the observation that the two forms interbreed often in nature and the offspring have good survival and reproduction. The earlier classification into two species was using a species concept; the reclassification is using the species concept. _________
Answer:
morphological; biological
Explanation:
The morphological species concept highlights the importance of physical traits to delimit species. This concept is useful for classifying asexually-reproducing organisms and where lack information on interbreeding (for example, to classify fossils). On the other hand, the biological species concept states that one species represent a group of organisms that can interbreed (or potentially can interbreed) in order to produce fertile offspring. The biological species concept is nowadays the most widely accepted concept to define species.

O Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same container. What does this tell you about the make-up of the pigments for each specimen?
Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.
Given RRYY x Rryy, what will the parents be? (no links please)
I'm guessing the genotypes given (RRYY x Rryy) are the offspring (if this isn't the case this answer may be wrong)
RRYY has both dominant alleles. So we can safely say that the parents are both RRYY.
For Rryy :
Rr is heterozygous (the alleles are not the same), so the parents could be:
RR x rr
RR x Rr
Rr x Rr
(if you do a small punnet square, you can double check these!)
Since yy has both recessive alleles, the parent is yy as well.

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.
~ #LearnWithBrainly ~
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.

compare and contrast the processes of mitosis (asexual reproduction) and meiosis (sexual reproduction).
Answer:
Diffrence:
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. parent. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all of the first generation of the offspring have red, axial flowers. The genes for flower color and location assort independently. If 1,000 second generation offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers
Answer: 750
Explanation:
Based off the first two sentences, we can conclude that red is the dominant allele and white is the recessive allele.
Let's say R = red and r = white.
The genoytypes of the parents are RR and rr. The genotype of the first generation are all Rr
The punnet square for the second generation is:
R r
R RR Rr
r Rr rr
We can see 3/4 crosses give us red. Now we can multiply 3/4 and 1000 to get 750.
7. A student astronomer went out and took photographs of the Moon that were several days apart.
Images that look like her photographs are shown above. The light part of the Moon appeared to get
smaller over time. Why did this happen?
a
Between the first photograph and the second photograph, the Moon moved farther away
from the sun so less sunlight reached the Moon's surface.
b
Between the first photograph and the second photograph, Earth moved so its shadow was
blocking more of the Moon so the student astronomer was able to see less of it.
