Answer:
The worker bees are female, but they do not breed. The queen bee is female and creates all the babies for the hive. The drone bees are male and do not have a sting. Bees communicate with each other about food sources using dances.

Answer:
Dendrochronologists have shown that tree-ring data produce a remarkably accurate history of droughts and other climate changes.
Explanation:
The underlying patterns of wide or narrow rings record the year-to-year fluctuations in the growth of trees. The patterns, therefore, often contain a weather history at the location the tree grew, in addition to its age. In dry environments, such as the Middle East or U.S. Southwest, tree rings typically record wet or dry years, and in cooler areas (high latitudes or high elevation), the ring widths are often a proxy for temperature.
Answer:
70 ml/beat.
Explanation:
Stroke volume may be defined as the volume of the blood that are pumped by the left ventricle in one contraction. The blood output can also be determined by knowing the stroke volume.
The stroke volume can be calculated by the formula as follows:
Stroke volume = End diastolic volume - End systolic volume
Here, end diastolic volume = 120 and end systolic volume = 50.
Stroke volume = 120 - 50
Stroke volume = 70 ml/ beat.
Thus, the answer is 70 ml/ beat.

Explanation:
2-deoxyglucose poison has its effects during glycolysis, which only produces 2 ATP, while Cyanide takes place during ETC which produces 34. If given the 2-deoxyglucose poison this would stunt the rest of the process very early on, so much so that no ATP could have been produced. So the ATP concentration would have decreased if given the other poison.
