A flask containing photosynthetic green algae and a control flask containing water with no algae are both placed under a bank of

lights, which are set to cycle between 12 hours of light and 12 hours of dark. The dissolved oxygen concentrations in both flasks are monitored. Predict what the relative dissolved oxygen concentrations will be in the flask with algae compared to the control flask. The dissolved oxygen in the flask with algae will always be higher. The dissolved oxygen in the flask with algae will always be lower. The dissolved oxygen in the flask with algae will be higher in the light, but the same in the dark. The dissolved oxygen in the flask with algae will be higher in the light, but lower in the dark. The dissolved oxygen in the flask with algae will not be different from the control flask at any time.

Answer:

The dissolved oxygen in the flask with algae will be higher in the light, but lower in the dark.

Explanation:

Photosynthetic algae as the name implies are capable of carrying out photosynthesis strictly in the presence of light. However, one major product of the photosynthetic process is OXYGEN GAS.

According to this question, an experiment consisting of two flasks is performed. One flask contains photosynthetic green algae and the other flask is a control flask containing water with no algae. Both flasks are placed under an intermittent cycle of 12 hours light and 12 hours dark.

This means that the flask with algae will photosynthesize in exposure to light and produce oxygen gas while it uses up the oxygen in the dark via cellular respiration. Therefore, in a nutshell, the dissolved oxygen in the flask with algae will be higher in the light due to photosynthesis, but lower in the dark due to cellular respiration.

Within a given species, which two types of cells have the equivalent amounts of dna?
kiruha [24]
The original question has a set of choices. This is within the context of cell division. The choices are:

A. A cell in G1 of interphase and a cell in G2 of interphase
B. A cell in G1 of interphase and a cell immediately after the completion of meiosis II
C. A cell in G1 of interphase and a cell in metaphase II of meiosis
D. A cell in G2 of interphase and a cell in metaphase II of meiosis
<span>E. None of the above.
</span>
The correct answer is C. A cell in G1 is diploid and the cell in meiosis II is haploid but the amount of DNA still equivalent as each chromosome in the haploid cell consists of two chromatids. G2 cells already had been through the S phase therefore the genetic material is already doubled. A cell immediately after meiosis II has half the genetic material.

If a body's rectal temperature cannot be taken, what other location can be used?
natali 33 [55]
The armpit isn't the most precise but it is close. Under the tongue, across the forehead, as long as you have the proper tools (thermometer, the thermometer meant for foreheads) you should get a fairly accurate reading.

Within each year, what is the pattern of change in CO₂ concentration? Why does this pattern occur?
telo118 [61]

The pattern of change in CO₂ concentration is new plant growth in the spring increases photosynthesis rates, which lowers CO2 concentrations; this decline continues until autumn, when leaves fall and decompose, raising CO2 concentrations.

The level of carbon dioxide within the surroundings rises and falls every 12 months as plant life, thru photosynthesis and respiration, absorbs the gas in the spring and summer season, and launches it in fall and wintry weather. Now the range of that cycle is expanding as extra carbon dioxide is emitted from burning fossil fuels and different human activities.

In spring, flora in the Northern Hemisphere starts to develop and absorb CO2 from the atmosphere, so atmospheric CO2 attention decreases as the road dives down. In fall, flora starts to decay and release their CO2 again into the ecosystem, so atmospheric CO2 attention increases the line shoots up. plants are accumulating carbon within the spring and summer while they are lively, and they're liberating carbon again to the air in the fall and winter.
