The transmission of DNA to offspring Increases in cell size and volume Processes by which individuals produce offspring Development into a multi-celled adultWhich statement regarding types of cells is accurate? a The presence of internal membranes indicates the ability of a cell to become multicellular and thus more complicated b Prokaryotic cells are smaller and simpler than eukaryotic cells c Eukaryotic cells are larger and more complex than prokaryotic cells d All cells maintain differing internal and external environments, regardless of construction
- Use the information below to answer the question Cell A = 1 μm x 1 μm x 1 μm Cell B=2 µm x 2 μm x 2 μm Cell C = 3 μm x 3 μm x 3 um How do the surface area-to-volume ratios compare for the cells listed above, and which cell would exchange the greatest amount of substances and waste products with its environment relative to its internal chemical activity? Assume the cells are cube-like. O a. The surface area-to-volume ratios increase from A to B to C, with cell A having the most rapid transport. O b. The surface area-to-volume ratios increase from A to B to C, with cell B having the most rapid transport O c. The surface area-to-volume ratios increase from A to B to C, with cell C having the most rapid transport O d. The surface area-to-volume ratios increase from C to B to A, with cell A having the most rapid transport. Oe. The surface area-to-volume ratios increase from C to B to A, with cell C having the most rapid transportestimate the number of cells there are in the human body taking the volume of a cell is v= 1000um^3 where 1um^3=10^-18m^3 anf the volume of human body 0.1m^3. write in scientific notation.Needs help describe the activities of each phase in an animal cell
- Tell whether the statement is true or false. if false, give the reason why the statement is wrong. 1. Cells come from pre-existing cells. 2. Robert Hooke first saw living organism in pound water 3. Microscope is used to study living organisms 4. Cells contain hereditary information passed from cell to cell during cell division. 5. Rudolf Virchow disproved the idea of spontaneous generationWhich statement is not part of the cell theory? All plant cells require nonliving material to function. All organisms are made of one or more cells. Cells are the basic units of structure and function in organisms. All cells come from preexisting cells.A plant cell and an animal cell are shown below. Plant cell Animal cell Which conclusion can be made from these diagrams? A Plant and animal cells interact to make new organisms. B Nerve cells are present in plant and animal cells. Animal cells require oxygen to release the energy stored in food while plant cells do not.
