Ribosomes produce proteins, the rough endoplasmic reticulum transports ribosomes made in the nucleolus to other parts of the cell, the smooth endoplasmic reticulum moves materials inside the cells, and the cytoplasm is the living substance that protects the cell and promotes chemical reactions.
Semi-conservatism is a property of DNA replication. According to this assertion, the DNA helix unwinds during the replication process and each strand acts as a template for the new strand that will be produced. Once a new DNA molecule has been produced, the old strand (the template) and the new strand combine to form a new double helix.
Synthesis, storage, transport, and detoxification are the four main jobs of the ER; phagocytosis is not one of them.
Only lysosomes can eliminate infections or damaged organelles. Fats and other organic substances are broken down by peroxisomes, which also neutralize harmful substances.
The "powerhouse" of the cell, the mitochondria, is responsible for converting chemical energy (sugars) into ATP during cellular respiration.
Several various RNA molecules participate in the translation process, each of which plays a specific role in the production of the functional protein. The messenger RNA (mRNA) that results from DNA transcription serves as the ribosome's reading template. The ribosomal complex is assembled with the aid of rRNA (ribosomal RNA). To add individual amino acids to the ribosome and prolong the polypeptide chain that is developing, tRNA (transfer RNA) is used.
Based on the passage, choice ( white dwarf star) is the correct response.
Cytosine, guanine, adenine, and thymine are used in DNA. Cytosine, guanine, adenine, and uracil are used in RNA. Both uracil and thymine cannot be found in either RNA or DNA.
The distance traveled by light in a year is measured in light-years (about 5.88 trillion miles)
When you open a soda can, the bubbles you observe are carbon dioxide gas that was dissolved in the soda under pressure. Carbon dioxide is not dissolved in any other compounds indicated in the other options using pressure.
This is a claim that cannot be proven scientifically. All of the others are capable.
One of the many roles that proteins play in the body is that of biological catalysts. Enzymes, which are these specialized proteins, help organisms carry out many different kinds of chemical reactions.
Ozone has no direct effect on the Earth's surface.
This is a symptom that no other mineral deficit possesses.
The amount of water vapor in the air is measured by humidity.
According to the passage, Pluto's density is closer to an asteroid than that of any of the planets. This might induce the reader to believe Pluto is an asteroid based on its density. However, the text claims that this is not the case and does not provide evidence to back up this claim. All of the statements in the other options are backed up by facts.
A cell with many mitochondria indicates that the cell has a high energy requirement since mitochondria produce the energy (ATP) that is needed by the cell.
Animal cells lack chloroplasts, the organelle that is responsible for photosynthesis in plant cells. Animal cells only have a cell membrane, whereas plant cells also include a cell wall. Animal cells have small vacuoles compared to plant cells' huge vacuoles. Plant cells lack centrioles, but animal cells do. Animal and plant cells each contain every other organelle.
While alcohol can harm other tissues as well, the majority of alcoholics first develop liver failure. One of the liver's functions is to remove toxins from the body.
The body is a toxin when it comes to alcohol.
DNA polymerase III requires a place of attachment to start DNA strand synthesis during DNA replication. Primase, which creates an RNA primer for DNA polymerase III to connect to, provides this template. DNA polymerase I is employed to convert the RNA primers into DNA nucleotides because RNA polymerase is only involved in translation and not DNA replication.
