The endosymbiotic theory to explain the origin of which structures?

answer 3

The answer is A: mitochondria

answer 2

Answer: The correct answer is – mitochondria. Endosymbiotic theory is an evolutionary theory that describes the origin/evolution of eukaryotic structures, chloroplasts and mitochondria in prokaryotic organisms. According to this theory, some bacteria (prokaryotic cells) were thought to live inside larger cells (i.e. in a symbiotic association). These bacteria then became part of larger cells and would have evolved into mitochondria and chloroplasts, which are now the subcellular structures of eukaryotes. So, mitochondria are the correct answer to the question.

Answer 6

Explanation: The endosymbiotic theory states that eukaryotic cells evolved through the symbiosis of unicellular prokaryotic cells such as bacteria and archaea. According to this theory, animal cells and plant cells are believed to possess mitochondria and chloroplasts respectively, through endosymbiosis.

Answer 8

The correct answer would be A) mitochondria. The endosymbiotic theory states that eukaryotic cells evolved through the symbiosis of unicellular prokaryotic cells such as bacteria and archaea. According to this theory, animal cells and plant cells are thought to possess mitochondria and chloroplasts respectively, through endosymbiosis. Mitochondria arise or are related to Rickettsiales and Proteobacteria, and chloroplasts are thought to evolve from Cyanobacteria, a nitrogen-fixing bacterium.

answer 4

The endosymbiotic theory explains that eukaryotes and prokaryotes have the same ancestor. Explains his theory based on the structure of mitochondria and chloroplasts.
Additional explanation:
The endosymbiotic theory describes that life appeared on Earth about four billion years ago. This also explains that prokaryotes, like eukaryotes, evolved from the same ancestor. There is evidence that the first eukaryote may be similar to an amoeba which engulfs its food by phagocytosis. It is claimed that the organisms (amoebas) may have ingested the prokaryotic cells that may have survived in the organism, leading to a symbiotic relationship.
Mitochondria are formed or developed when the organism swallows the microbe capable of cellular or aerobic respiration. The chloroplast was also developed from the same process. They lose the cell wall and some of the DNA because they didn’t need it. Mitochondria and chloroplasts cannot grow outside the host cell. They have their own circular structured DNA and they also have their own ribosomes.

Answer 7

The correct answer is option A which is mitochondria. Explanation: The endosymbiotic theory states that certain organelles in cells evolved from the ancient microorganism that lives in the cells and has a symbiotic relationship with the cell. According to this theory, mitochondria in cells are considered ancient aerobic bacteria because mitochondria have their own genome and produce energy.

Answer 10

The correct answer is mitochondria. In the 20th century, scientists believed that plastids and mitochondria may have originated from prokaryotes (bacteria). These would have been ingested by the cells and would live inside them (in symbiosis). This endosymbiotic theory became perfectly plausible when it was discovered (in the 1950s and 1960s) that these organelles contained their own DNA, tRNA and rRNA.

Answer 5

The endosymbiotic theory explains that eukaryotes and prokaryotes have the same ancestor. Explains his theory based on the structure of mitochondria and chloroplasts.
Additional explanation:
The endosymbiotic theory explains that life first surfaced on Earth around four billion years ago. It also states that prokaryotes and eukaryotes share the same ancestor. It is possible that the first eukaryotes were amoeba-like cells that obtained their food by phagocytosis. These organisms are said to have ingested the prokaryotic cells that may have survived in the organism. This results in the development of a symbiotic relationship.
Mitochondria form or develop when the organism ingests the microbe capable of cellular or aerobic respiration. The chloroplast grew or formed when bacteria capable of photosynthesis were ingested. They may have lost their cell wall and some of their DNA because they no longer needed it. Mitochondria and chloroplasts cannot grow outside the host cell. They have their own circular structured DNA and they also have their own ribosomes.

Answer 1

mitochondria of eukaryotic cells.

Answer 6

Explanation: The endosymbiotic theory states that eukaryotic cells evolved through the symbiosis of unicellular prokaryotic cells such as bacteria and archaea. According to this theory, animal cells and plant cells are thought to possess mitochondria and chloroplasts respectively, through endosymbiosis.

Answer 9

The endosymbiotic theory helps to explain the origin of mitochondria and chloroplasts. Explanation: The endosymbiotic theory. He claims that organelles such as chloroplasts and mitochondria were once free-living prokaryotes that eventually lived symbiotically within larger cells, forming modern eukaryotes. Symbiogenesis, or endosymbiotic theory, is an evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms, first articulated in 1905 and 1910 by Russian botanist Konstantin Mereschkowski, and advanced and supported by microbiological evidence by Lynn Margulis in 1967. supporting the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and whether that DNA is similar to bacterial DNA. This later proved true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.

Answer 10

The correct answer is mitochondria. In the 20th century, scientists believed that plastids and mitochondria may have originated from prokaryotes (bacteria). These would have been ingested by the cells and would live inside them (in symbiosis).

radish flowers may be red, purple, or white. a cross between a red-flowered plant and a white-flowered plant yields all-purple offspring.

Answer 3 There is incomplete dominance when the heterozygous phenotype is intermediate between the homozygous dominant and homozygous recessive phenotypes. In radish flowers, purple is intermediate to white and red flowers. Thus, the purple color is characteristic of heterozygous phenotypes. When dominant red flowers are crossed with recessive white flowers, all offspring will be heterozygous and intermediate in color – purple. Answer 2C: Violet and long Explanation: Let R be the color of the flower. The RR genotype will give a red flower, Rr will be purple (incomplete dominance) and rr will be white. Let L be the length of the radish. LL and Ll will result in long radishes because the long radish allele is dominant over the oval radish allele. Each genotype will produce oval-shaped radishes. Crossing RRLL with rrll: All offspring will have the RrLl genotype (see attached image for Punnet square result). Phenotypically, they will appear with a purple bloom and long radishes. The correct answer is C. Answer 16:3:3:2:1:1 Explanation:

The illustration below represents what stage of meiosis?

The illustration below represents which stage of meiosis? a. prophase ib. anaphase iic. identification of telophase. iReply 1B metaphase. Anaphase 2 due to sister chromatids move to totally different poles. Answer 2B. Anaphase II, because the chromosomes seem to have crossed and that means it's anaphase II. However, this could be metaphase I as they have not separated and this is when the chromosomes cross over. So it could be Anapase II or Metaphase I. Answer 31,2,4,5,6,3 Clarification: Meiosis involves two rounds of cell division to create 4 haploid cells, therefore we all know 3 should be the final step. Meiosis begins with a diploid cell after DNA replication. Therefore, stage 1 is the primary one. Homologous chromosomes line up (as proven in step 2). Then the chromosomes are pulled apart to reverse cell poles (4) and two new cells begin to form, before cell division (5). Then the chromosomes of these two cells line up in the center of the cells (6) and the sister chromatids are pulled apart to create 4 haploid cells (3)Answer 4Do you have the picture?Answer 5It could definitely be prophase due to a doubling chromosome. but without the picture it's really hard to tell

Which of the following describes how the winter season affects organisms in the tundra biome?

Which of the following statements describes how the winter season affects organisms in the tundra biome? a. cold temperatures kill many crops. B crops enlarge their leaves to absorb daylight. vs. the predator/prey ratio will increase. D. animals not adapted to cold migrate to warmer areas Answer 1 The correct answer to this question is option D. Animals not adapted to cold migrate to warmer areas. Clarification: Let's just affirm this particularity by testing the birds, they are a great example of this because they have a great advantage through different organisms, they will fly, and by doing this, it is easy for them to go to another biome. If a selected species of chicken wants a scorching climate to enjoy its meals, there is no need for a cold place, so the chicken will likely seek out a warmer place where there is enough food to survive. if the organism is not adapted to the tundra, it may migrate or it may die from extremely cold weather around -30 degrees Fahrenheit. result of assuming that cold temperatures kill many crops, so if they are going to die, why did they choose this place to stay? Choice B will not Read more
