Answer:
Option A, Cytoplasm
Explanation:
Cytoplasm is the fluid contained with in the cell membrane into which all cell organelles are found including the nucleus. Cytoplasm basically has two parts a) endoplasm and b) ectoplasm. The endoplasm has all the organelles while the ectoplasm is the fluid at the periphery of cell membrane. The cell memebrane keep the cytoplasm confined with in the cell and does not allow it to spill.
Since all the cell components are found with in the cytoplasm, it is clear that cytoplasm lies out of the nucleus. Thus, option A is correct.
Answer:
The correct answer will be option- A
Explanation:
The nucleus is the membrane organelle which encloses the DNA of the organisms. The presence of the nucleus is the characteristic feature of the eukaryotes.
The nucleus encloses the genetic material in the form of either DNA or a loosely arranged structure called chromatin. The nucleus also contains a structure called nucleolus distinguished by a dense round structure during the interphase.
Since the nucleus lacks the cytoplasm which is enclosed by the cell membrane of the cell therefore, option-A is the correct answer.
Individuals 2, 3, 4, and 5 are affected by Leigh's disease. It is passed down from the mother to her offspring through the mitochondria.
Leigh's disease is a mitochondrially inherited disease,The pedigree shows the presence of Leigh's disease in three generations, indicating that it is maternally inherited.
Individuals 2, 3, 4, and 5 are affected by Leigh's disease because they show symptoms of the disease, such as seizures, ataxia, and impaired reflexes. Their symbols on the pedigree should be shaded in to indicate that they are affected.
Individuals 1, 6, 7, and 8 are not affected by Leigh's disease because they do not show any symptoms of the disease. Their symbols on the pedigree should be left unshaded to indicate that they are unaffected.
Individuals 4 and 6 both had children, but the information provided does not indicate whether their offspring were affected by Leigh's disease or not. Therefore, their symbols on the pedigree should be left unshaded.

b. an excretory system that includes a pair of kidneys.
c. a system of muscles that enable movement.
d. all of the above
The answer is Omnivores.
Omnivores are the type or kind of animals who eats on either animals or plants. An example of an omnivore is a bear. Bears eat on berries, salmons, fungi, and other insects. Various mammals are omnivores in the wild.
Answer:
organism, called Paramecium. The contractile vacuole is a specialized organelle responsible for maintaining osmotic balance and regulating the water content within the cell. Paramecium lives in freshwater environments, where water continuously enters the cell through osmosis. The contractile vacuole collects excess water from the cytoplasm and pumps it out of the cell through a series of canals. This process helps Paramecium prevent the cell from bursting due to excessive water intake. The contractile vacuole also helps in removing waste materials from the cell. The picture shows a spherical contractile vacuole with multiple canals leading to the cell's surface, through which water is expelled. Overall, the contractile vacuole is a vital organelle for maintaining the internal balance and survival of unicellular freshwater organisms like Paramecium.
B. study their genetic make-up
C. study their shape and arrangement
D. conduct Gram staining
E.study how they gain energy and nutrients
F. study how they move
If you wanted to try and identify or classify archaea or eubacteria, you would study their habitat, study their genetic make-up, study their shape and arrangement, conduct Gram staining, study how they gain energy and nutrients and study how they move. Archaea and eubacteria are genetically different; Archaea have more complex RNA polymerases that contain multiple polypeptides while eubacteria have simple RNA polymerases that contain four polypeptides. Archaea cell walls do not contain peptidoglycan while almost all bacteria cell walls contain peptidoglycan.
