A sprinter would experience muscle fatigue sooner than a marathon runner due to?
Muscle fatigue sooner due to anaerobic metabolism in the muscles of the sprinter.
Anaerobic metabolism creates energy by burning carbohydrates in the absence of oxygen. This happens when your lungs can't put sufficient oxygen into the bloodstream to keep up with the demands of your muscular tissues for energy. Anaerobic metabolism, which can be described as ATP production without oxygen (or in the absence of oxygen), occurs by direct phosphate transfer from phosphorylated intermediates, together with glycolytic intermediates or creatine phosphate (CRP), to ADP forming ATP.
Anaerobic metabolism at the cellular stage occurs when oxygen transport and tissue oxygenation are compromised. this can be a result of hypoxemia, anemia, inadequate systemic blood waft, or a mixture of these factors.

b. less than 10,000 years
c. 100,000 to 1 million years

a. 10–100 million years is the answer.
Solar mass stars are thought to accrete rapidly. Premain sequence solar mass protostars are probably formed by the collapse of part of a molecular cloud into the "cloud core" in about 105 years (Hartmann, 2000). Strong outflows and jets are sometimes observed.
Star formation begins with the collapse of molecular clouds and fragmentation into highly dense masses. These masses initially contain about 0.01 solar masses, but increase in mass as the surrounding matter is collected by accretion.
Protostars are very young stars, still collecting mass from their original molecular clouds. The protostar stage is the earliest in the process of stellar evolution.

The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cells?
endoplasmic reticulum
ribosomes
cell membrane
lysosomes
peroxisomes
vesicles
large central vacuole
Golgi complex
cytoskeleton
mitochondria
cell wall
Answer:
large central vacuole
cell wall
Explanation:
Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.
Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.
ANSWER:
Both plants and animals are multicellular, eukaryotic organisms and most of the organelles in cells of animals and plants are similar, such as cell membrane, nucleus, mitochondria, endoplasmic reticulum, and ribosomes.
However, there are some organelles that are only found in plant or animal cells. Organelles that are found only in plant cells include chloroplasts, cell wall, and large central vacuoles. The cell wall provides rigidity and protection to the plant cells, chloroplast help in photosynthesis, and large vacuoles act as storage organelles.
Thus, the correct options are 'chloroplasts, cell wall, and large central vacuole.'

What kind of traits found in a group of organisms provides the strongest evidence for common ancestry of that group? Although the characteristics are similar, they serve various purposes in the group members.
What is common ancestry?The idea that all cellular life forms on earth share a single genesis is widely held. The universality of the genetic code and the universal conservation of several genes, especially those that code for essential elements of the translation system, support this viewpoint. By contrasting the capacity of a common-ancestry model with a multiple-ancestry model to predict the sequences of universally conserved proteins, an impressive recent work asserts to provide a formal, homology independent evaluation of the Universal Common Ancestry hypothesis.
