After several miles of running and sprinting in intervals, the runner’s muscles ache and feel fatigued. Which is the best explanation for what has occurred?
The runner's muscles have accumulated lactic acid.
The runner’s body has failed to perform cellular respiration.
The runner’s cells are relying completely on aerobic respiration.
The runner’s muscles have accumulated carbon dioxide.
Answer:
A
Explanation:
Just did the Unit Test
When the body is subjected to vigorous exercise, lactic acid tends to build up in the muscles, hence, the most probable explanation for the fatigue felt by the runner is the accumulation of lactic acid in the runner's muscle
When the body is subjected to vigorous exercise such as running several miles as performed by the subject in the question, lactic acid accumulates temporarily in the muscles. This temporary build up of lactic acid in the muscles causes feeling of fatigue or weakness as the body tends to become short of oxygen required to breakdown the glucose in the blood.Therefore, the runner most probably has accumulated lactic acid in his muscles.

A (Freud-influenced) psychologist coming from a psychoanalytic or psychodynamic perspective is most likely to say: "Science must be rooted in observation of behavior, rather than introspective processes." "A person needs unconditional love and acceptance in order to reach her true potential." "A person's behavior reflects unconscious conflicts and emotions that result from early childhood experiences." "Emotional responses reflect biological processes such as hormones and brain chemistry."
Answer:
"A person's behavior reflects unconscious conflicts and emotions that result from early childhood experiences."
Explanation:
Psychoanalytic perspective: In psychology, the term "psychoanalytic perspective" was proposed by Sigmund Freud. The main idea of psychoanalytic perspective is to focus on the significance of an individual's unconscious mind rather than his or her conscious mind. However, it specifies that an individual's behavior is being governed by his or her past experiences or childhood experiences.

Why are the water weed cells green, but the onion cells are not? Answer in complete sentences. WILL MARK BRAINLIEST!!!
Answer:
Water Weeds have a main extra feature that plant cells have is a cell wall on the outside. So it's mostly made of cellulose, which gives a tough covering on the outside of the cell membrane. And therefore, gives plant cells a distinctive polygonal outline. And the reason why Onion cells aren't green is that cells deep within the structure of plants are not green. Second, not all onion cells are lacking in green color. The bulb of the onion lacks green, but the stem and leaves of the onion plant are green. The reason the bulb is white, and not green is that it has no chlorophyll.
- Hope this helps
Chlorophyll, a distinctive green substance (pigment), fills the chloroplasts. The cell uses this green pigment to absorb light photosynthesis. Cells in onions are not green. No light, hence bacteria don't require chloroplasts.
What does chlorophyll do for your body?Supplement companies assert that chlorophyll has a wide range of benefits, and including ability to increase red blood cells, aid in weight reduction, mend damaged skin, remove toxins, reduce inflammation, and prevent cancer. It's an amazing list, yet only a few of the statements are supported by research. nausea while your digestive system processes the chlorophyll. vomiting, which can harm your teeth by producing stomach acids.
Is it safe to take chlorophyll everyday?An abundance of essential vitamins and minerals may be found in chlorophyll extracts, which also have great pro government, antibacterial, and antioxidant properties. Chlorophyll can be used daily without harm, albeit the recommended quantity varies depending on the type of green you eat. Consuming saffron milk, peppermint tea, clove tea, green tea, protein drinks, green vegetable smoothies, etc fiber-rich juices will drastically reduce you body fat over night.

Which of the following organic molecules are classified as carbohydrates?
amino acids
O nucleotides
O sugars
O fatty acids
The organic molecules that are classified as carbohydrates are ; ( C ) Sugars
Carbohydrates are classified as monosaccharides, disaccharides, and polysaccharides. under the monosaccharides we have the simple sugar with formula ; C₆H₁₂O₆ .
When carbohydrates rich food substances are consumed they are broken down into sugar so that the human body can easily absorb it. therefore the organic molecules that can be classified as carbohydrates are sugars while proteins are broken down into amino acids.
Hence we can conclude that The organic molecule that is classified as carbohydrates is ; ( C ) Sugars

PLEASE HELP QUICK! Analyze evidence from the lesson regarding the origins of cell compartmentalization. Then make a claim about the origin of cell compartmentalization based upon the evidence presented, stating two to three reasons for the claim. Provide evidence and specific examples that support each reason for the claim. Provide a conclusion to the short essay.
Answer:
Explanation:
Both organelles, the mitochondria and chloroplasts (in photosynthetic organisms), are compartments that are believed to be of endosymbiotic origin.A compartment is a separate space within a larger whole. In relationship to the endomembrane system and the nucleus.organelles that aren’t part of the endomembrane system, such as mitochondria and chloroplasts.Cellular compartmentalization allows cells to optimize the efficiency of the processes that occur within organelles. But despite the advantages of compartmentalization, it’s not a universal feature of life. In fact, compartmentalization of cellular functions into membrane-bound organelles is limited to only one of life’s three major groups, or domains. That domain is the one that we belong to, the Eukarya. In addition to animals, eukarya includes plants, fungi, and other organisms with eukaryotic cells: cells that are relatively large, complex, and compartmentalized. And to see why that is, we need to look at how life has diverged over time.
The process in which the cellular compartments are made are called as cell compartmentalization. Various species are having the different types of organisation such that the functioning is different as well.
What is the name of the primitive cell ?It is the prokaryotic cell in which the cell organelles are not well defined and with that the species are developing advanced features.
Prokaryotes have the cytoplasm in the scattered which the cell organelles are present in the cytoplasm and floating out there and compartmentalization is commonly described as a different feature of eukaryotic cells and is also present in the prokaryotic cells in form of protein-bounded along with the lipid-bounded organelles.
In the eukaryotic cells the compartmentalization is made by the use of pattern of internal membranes. These membranes surrounds the nucleus and create the folds of the endoplasmic reticulum along with Golgi complex and surround organelles like chloroplasts and mitochondria.
