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.

Alcoholic fermentation:___________
Irina-Kira [14]

Alcoholic fermentation includes: <u>All answers are correct</u>

a. is carried out by yeasts.

b. produces far less ATP than aerobic respiration.

d. produces ethanol.

e. produces carbon dioxide.

Fermentation- Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals.

Aerobic respiration- It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.

“The study of cell biology is directly
Marat540 [252]

Answer:

I agree.

Explanation:

Cell biology and technology are so connected that there is even a science called biotechnology, which is the literal union of these two strands.

Biotechnology is an area that aims to develop biological products and processes with the help of science and technology. The United Nations (UN) classifies biotechnology as "any technological application that uses biological systems, living organisms, or derived beings, to manufacture or modify products or processes for specific uses".

Biotechnology covers different areas of knowledge that include basic science (such as molecular biology, microbiology, etc.), applied science (such as immunological, chemical and biological techniques) with different technologies (such as information technology, robotics and process control).
