Mitochondria and chloroplasts are the two organelles that have their DNA separated from the DNA contained in the nucleus.
Organelles are the specialized organs for a eukaryotic cell to perform various functions. They are usually protected by a membrane(s) and are found in the cytoplasm of the cell. The various organelles found in a eukaryotic cell are the nucleus, peroxisomes, lysosomes, mitochondria, chloroplasts, ribosomes, Golgi apparatus, and endoplasmic reticulum.
The nucleus is the site for DNA replication. It then produces RNA by the process of transcription. This RNA is then transferred to ribosomes for protein synthesis. These synthesized proteins are then transferred to various cell organelles to perform their specific functions.
Meanwhile, the mitochondria and chloroplasts are the two organelles that do not need proteins synthesized by the ribosomes. They can synthesize their proteins themselves as they have their DNA separated from the DNA of the nucleus. Because of this characteristic, they are also referred to as semi-autonomous.

It might be a case of food poisoning caused by bacteria like E.coli.
A disease called food poisoning caused by eating spoiled food. Most people recover within a few days without treatment and are usually not dangerous. Food is usually contaminated with bacteria such as salmonella and E. coli, or viruses such as norovirus in the case of food poisoning. Symptoms of food poisoning usually appear 1 to 2 days after eating contaminated food. It can occur after a few weeks. Rest and hydration are recommended until you feel better to avoid dehydration. Make sure you drink enough water, even if you can only swallow it. Eat whenever you feel hungry, but start with small, light meals.

Which statements describe scientific laws but not theories or hypothesis?check all that apply
They don't offer justifications for why they are accurate. They are regarded as established facts.
A theory essentially means the opposite. A well-supported explanation of a phenomenon in the natural world, including laws, hypotheses, and facts, is called a theory.A hypothesis is a statement about the natural world that can be verified by observations or tests. Hypotheses must be falsifiable—that is, they must be formulated in a fashion that allows them to be disproven—and be evaluated scientifically in order to be considered to be true.Scientific laws or laws of science are propositions that describe or forecast a variety of natural occurrences and are based on repeated tests or observations.Scientific rules condense the findings of tests or observations, typically within a specific applicability range. The accuracy of a law typically does not change when a new theory of the relevant phenomenon is developed; rather, the law's application area expands because the mathematics or statement that represents the law remains constant.Therefore, scientific laws, theory, and hypothesis are different aspects of Science.

Which vertebrae type is characterized by a large size and wide, kidney-shaped body?.
Answer:
The lumbar vertebrae is characterized by a large size and wide, kidney-shaped body.
Explanation:
The vertebral column is formed of four different types of vertebrae: the cervical vertebrae, the thoracic vertebrae, the lumbar vertebrae, and the sacrococcygeal vertebrae, in order from head to hip.
cervical vertebrae They generally have a smaller body and larger vertebral foramen, and are known as the smallest types of vertebrae. Their spinous process is bifid, meaning that the spinous processes are divided into two segments. In the cervical vertebrae, the two segments are unequal.
The thoracic portion of the body contains the rib cage, also the thoracic vertebrae too have undergone a modest alteration to allow for this.
The sacrococcygeal area, which includes the sacrum as well as the coccyx, is frequently examined in connection. The sacrum is typically short and broad in females while it is lengthy and narrow in men. The tail's last remaining piece is the coccyx.

Radioisotopes of radiolabelled sugars are attached to proteins within the Golgi apparatus and are used for their study of function and it is a membrane-bound organelle found in eukaryotes. It is made up of flattened, stacked pouches called cisternae. Proteins and lipids are moved, altered, and packaged into vesicles by the Golgi apparatus and delivered to specific locations. It is situated close to the cell nucleus and the endoplasmic reticulum in the cytoplasm.
In an experiment to determine the route secreted proteins follow, radioactively labeled amino acids are added to a growing culture of cells involved in protein synthesis. The secretory vesicles received the radiolabeled proteins from the Golgi apparatus, which then moved there and joined with the plasma membrane to release them outside the cell.

When the body's digestive system breaks down starch, a complex carbohydrate, into simpler carbohydrates, the reaction is:________
The reaction is catabolic. Catabolism is a series of metabolic pathways that break down molecules into smaller units, either oxidized to release energy or used in other anabolic reactions.
Among complex carbohydrates, starch serves as the main glucose storage molecule in plants. A large number of different glucose monomers combine to form starch and are linked by glycosidic bonds. An example of a catabolic reaction that releases chemical energy is the breakdown of starch, a complex carbohydrate, by the body's digestive system into simpler carbohydrates. C. Catabolic, which causes the release of energy, is the correct response. The anabolic process is incorrect because an anabolic reaction involves the synthesis of less complex monomers into more complex monomers. Catabolic processes also lack the ability to store energy.Therefore, catabolic reaction is the correct answer.

Damaged tissues are normally repaired through replacement of damaged or dead cells through a process called regeneration, hence, it is false.
Damage to tissues can occur internally or externally. When this occurs, a series of events called tissue repair are set in motion to contain the damage and initiate the healing process. One of these processes is called regeneration.
When the body replaces damaged or dead cells using cells of the same type, it is called regeneration. This occurs in most skin injuries like cuts, minor burns or scrapes and often doesn't leave any major scar. The internal organ that regenerates outstandingly well is the liver. Since the same type of cells are used during regeneration, the normal function of the organ is restored after regeneration.
