What are "Chloroplasts"? a. an organelle of some eukaryotic cells in which photosynthesis occurs, using the energy of light to make organic compounds from carbon dioxide and water

b. the substance inside a cell, prokaryotic or eukaryotic, including organelles, but
not including the nucleus of a eukaryotic cell

c. membrane-bound organelles in eukaryotic cells in which cellular respiration
takes place, using oxygen to break down glucose to carbon dioxide and water

d. a cell organelle that is essential to cell functions including reproduction, contains
the cell's chromosomes, and is enclosed by a membrane

Populations of blue-winged warblers, a type of bird, migrate south in the winter and return to canadian breeding grounds in the spring. as global temperatures have increased due to climate change, spring has started arriving in the warbler's breeding grounds earlier in the year, before the warblers return. warblers now arrive at their breeding grounds too late to select ideal nesting sites and to feed on important early-spring food sources how are populations of blue-winged warblers most likely to be affected by the earlier arrival of spring? o a. populations will go extinct since the warblers will stop migrating to breeding grounds. b. populations will be unaffected since most species can quickly adapt to effects of climate change. c. populations will increase since warmer temperatures are generally beneficial to survival, d. populations will decline since individuals will be less likely to successfully reproduce, reset next

Four different thermometers were used to measure the temperature of a sample of pure boiling water. the measurements are recorded in the table below. thermometer temperature reading 1 temperature reading 2 temperature reading 3 w 100.1°c 99.9°c 96.9°c x 100.4°c 102.3°c 101.4°c y 90.0°c 95.2°c 98.6°c z 90.8°c 90.6°c 90.7°c the actual boiling point of pure water is 100.0°c. what can be concluded from the data about the reliability and validity of the thermometers?
