Well The body converts glucose to energy which produces lactic acid as a by-product. As that builds up in the muscles, it begins causing cramps and fatigue as a signal to stop. So you have to stop when you reach the lactate threshold. And Over the course of a sustained run at half-marathon pace or faster, the amount of energy (and thus oxygen) needed to maintain that pace gradually inches upward. Over the course of 10-20 minutes, your oxygen consumption can drift upward by as much as 25 per cent, making it progressively harder for you to Hold up.
I Hope this Helps! May I Have brainliest? <3
I would be unable to run forever without my muscles giving out is as a result
of stress , shortage of glucose and build-up of lactic acid.
When activities are performed by muscle tissues , the glucose is usually
converted to energy with the release of lactic acid.
The shortage of glucose and build up of lactic acid brings about fatigue and
wearing out of the tissues thereby making us unable to run forever.

(06.02 MC) Which of the following correctly explains the role of antibiotics in the human body? (2 points) a They break down damaging toxins created by bacteria. b They increase the number of white blood cells in the blood. c They rupture the cell wall or prevent protein synthesis in bacteria. d They reduce the effects of fever, swelling, and inflammation in the body.
Answer:
The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.
Explanation:
Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.
The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:
Destruction of the bacterial wall or membrane. Interference with protein synthesis. Inhibition of the synthesis of nucleic acids.In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.
The other options are not correct because:
a. Breaking down damaging toxins created by bacteria is an anti-toxin function.
b. Antibiotics do not increase the number of white blood cells in the blood.
d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.
Answer:
They rupture the cell wall or prevent protein synthesis in bacteria.

how does each of your mutations affect the amino acid sequences? Are the mutations missense mutations, silent mutations or nonsense mutations?
a. Point mutation?
b. Frameshift-insertion?
c. Frameshift-deletion?
Answer:
the correct answer is B Frame shift insertion
Explanation:
plz give me brainiest
Frameshift-insertion mutations affect the amino acid sequences.
Thus, The insertion or deletion of nucleotide bases in amounts that are not multiples of three is referred to as a frameshift mutation in a gene.
This is significant because a cell reads the genetic code for proteins in groups of three nucleotides.
These so-called "triplet codons" each stand for one of the 20 different amino acids that go into making a protein. This normal reading frame will be disrupted by a mutation, which will result in an inaccurate reading of the entire gene sequence after the mutation.
Thus, Frameshift-insertion mutations affect the amino acid sequences.

What happens to a substance when it is heated?
a
Thermal energy is decreased
b
Potential energy is increased
c
Kinetic energy is increased
d
It does not change its physical shape
Answer: C
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster: the space between atoms increases: The motion and spacing of the particles determines the state of matter of the substance: The end result of increased molecular motion is that the object expands and takes up more space.

Proteins are synthesized based on genetic information carried by DNA. Explain how the structure of DNA is important in the synthesis of different kinds of proteins. In your explanation, include a description of the two main processes involved in protein synthesis.
Answer:
One of the single most significant biological processes that individual cells are capable of would be building their specific proteins. This process is referred to as protein synthesis. DNA (deoxyribonucleic acid) and RNA (ribonucleic acids) are involved in protein synthesis, which occurs in the given cell's nucleus. The DNA has a unique structure vital for distinct enzymes to unwind in a specific section of DNA. This, in turn, makes that section accessible for an RNA copy to be made. Once made, the RNA molecule moves from the given cell's nucleus to its cytoplasm, where, finally, the actual protein synthesis process can occur.
Explanation:
took me awhile to research this
Proteins are synthesized by the DNA through the processes of the central dogma. Proteins are essential for cell growth, functioning, structural arrangement etc.
DNA is a double-stranded nucleic acid that contains genetic codes and information. DNA replicates to form two daughter cells by the process of replication.
The duplicated DNA serves as a template for the construction of RNA by the process of transcription. The unique double helix of deoxyribonucleic acid makes it accessible for the formation of mRNA.
The single-strand RNA have nucleotide bases that code for the amino acids with the help of tRNA and ribosomes by the process of translation.
The amino acids produced bonded together to create proteins.

Larger lions have 15,000 kcal on average to expend per day and need to gain more than that to survive. If lions can only hunt less than 3 times per day, explain how lions obtain food with the lowest cost and greatest energy benefit.
Answer:
warthog
Explanation:
1. Zebra burns too many calories when its hunted
2. Warthog when times 3 times makes 15k calories
3. Wildbeast would exhaust the lion and meerkats wouldnt give it enough calories
Larger lions should hunt on warthog as from hunting these organisms they get more energy as compared to the energy required for hunting. Lions will get 12,000kcal per hunt of a warthog.
What is energy flow?Energy flow is the flow of energy in an ecosystem through different living organisms. The flow is unidirectional i.e., it starts with the Producers and goes on to the primary consumers and further to secondary consumers in a food chain. Each level in a food chain is known as a trophic level.
Energy flow in an ecosystem follows the 10% law where, only the 10% of the energy present at the previous trophic level is transferred to the next trophic level.
In this question, larger lions needs to hunt for survival and have 15,000kcal energy to expend per day. They need to get maximum energy from hunting less than three times a day. So, by hunting on warthog they expend 5,000kcal of energy and get 12,000kcal per kill. This way they get maximum energy from hunting three warthogs, i.e., 12,000×2 = 24,000kcal from expending 10,000kcal energy.

what process is responsible for creating magnetic changes along mid-ocean ridges
Answer:
Sea floor spreading
Explanation:
The process responsible for creating magnetic changes along the mid-ocean ridges. Sea floor spreading entails the movement of the lithosphere over the weak and fluid asthenosphere. At the spreading center new oceanic crust is created.
The earth is surrounded by a magnetic field. Magnetic minerals in fresh magma orients in the direction of prevalent magnetic field when they begin to cool and solidify.
Due to changes in the magnetic field direction and the upwelling of new magma, the magnetic patterns in a rock changes.
What has no nucleus and a large surface area?
Answer:
prokaryotic cells
Explanation:
a example of a prokaryotic cell would be a blood cell they have no nucleus and a large surface.
Answer:
The answer would be Prokaryotic Cells
Explanation:
A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. These Prokaryotic cells are not divided up on the inside by membrane walls, but consist instead of a single open space.
The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid, and it typically consists of a single large loop called a circular chromosome. So technically these cells lack nucleuses, while still containing genetic material(s).

What is the starch indicator, and how does it change?
Answer:
Starch is a indicator in the iodometric titration and it turns deep dark blue when iodine is present in a solution. The starch under warming condition forms amylose and amyl pectin's which combine with iodine to produce dark blue color. In absence of iodide ion starch indicator is colorless.
Explanation:
Starch is a viable indicator in the titration process because it turns deep dark blue when iodine is present in a solution. When starch is heated in water, decomposition occurs and beta-amylose is produced. Beta-amylose combines with iodine, resulting in a dark blue color change. The iodine-starch test is a chemical reaction that is used to test for the presence of starch or for iodine. The combination of starch and iodine is intensely "blue-black". The interaction between starch and triiodide is the basis for iodometry. In an iodometric titration, a starch solution is used as an indicator since it can absorb the I2 that is released. This absorption will cause the solution to change its color from deep blue to light yellow when titrated with standardized thiosulfate solution. This indicates the end point of the titration. Aside from their basic nutritional uses, starches are used in brewing and as thickening agents in baked goods and confections. Starch is used in paper manufacturing to increase the strength of paper and is also used in the surface sizing of paper. When starch is heated in water, various decomposition products are formed, among which is beta-amylose which forms a deep blue-black complex with iodine. The starch indicator solution must be freshly prepared since it will decompose and its sensitivity is decreased.
