Identify the process seen in the picture and write a short note on it.

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 endosymbiotic theory proposed that the mitochondria and the chloroplast evolve from some types of bacteria which the eukaryotic cells engulfed.

The endosymbiotic theory tries to explain how the eukaryotic cells came into existence from prokaryotic cells. According to this theory, the eukaryotic organelles like the mitochondria and the chloroplasts were actually free living prokaryotes and were taken in one after the other via endosymbiosis.

This theory has been backed by evidences which establish the phylogenetic similarity between mitochondria and bacteria and also between chloroplast and cyanobacteria. The evidences include the presence of circular DNA in both chloroplast as well as the mitochondria and also the fact they divide by binary fission like bacteria.

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.

If a mutation occurs when forming a germ cell the mutation could be passed on to the next generation. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gametes will carry the mutation and it will be passed on to the next generation when the individual successfully mates.

A mutation passed to the next generation when acquired mutation occurs in an egg or sperm cell. Once an acquired mutation is passed down, it is a hereditary mutation. Acquired mutations are not passed down if they occur in the somatic cells, meaning body cells other than sperm cells and egg cells.

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.'
