None of the provided options are reasonable. <span>comparing nutrient concentrations between the photic zone and the benthic zone can not tell you whether differences in concentrations between the photic and benthic zone are due to uptake by phytoplankton or because nutrients are sinking to the sea bottom and ocean stratification is preventing mixing. The approach of c</span><span>ontrasting nutrient uptake by autotrophs at different locations under different temperatures would not provide useful information on limiting nutrients. but rather uptake rates at different temperatures. It is likely that e</span>xperimentally enriching some areas of the ocean and compare their productivity to that of untreated areas can provide an indication of limiting nutrients, but this is not advisable, as it would have to be done on a large scale, and one cannot be sure of the ecological consequences. Also, because it would not be a controlled experiment, other factors could create 'noise' in the data. The last option, <span>observe antarctic ocean productivity from year to year to see if it changes, also does not help, as there is no correlation between nutrient concentrations using this approach. The best approaches would be either the last approach, but with the additional monitoring of nutrient concentrations, or under a controlled laboratory experiment.</span>
Answer:yes
Explanation:natural selection does produce a change in individuals as well as populations. Explanation: Natural selection is a process through which mother nature screens for the organisms that are best adapted to survive in a habitat.
Answer: I included a labeled graph of both a plant cell and an animal cell. I don't know if you needed an explanation of what they do, too, but I'll include it anyway.
Explanation:
The Cell Membrane, or plasma membrane, provides protection for the cell. It also transports substances in and out of the cell.
The Cell Wall (only plants) provides the structure for a plant, as well as added protection.
The Mitochondria are the powerhouse of the cell, providing energy for our cells to do their work. They produce a small molecule called ATP (adenosine triphosphate), where the energy is stored and sent to where it is needed.
The Lysosomes are the waste facilities of cells. They breakdown excess or worn-out cell parts, destroy foreign or invading bacteria, and digest macromolecules (carbs, lipids, proteins, and nucleic acids)
Answer:
a. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
Explanation:
Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.
On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.
Option B: during cellular division, the nuclear membrane dissolves and the DNA strands unwind.
