Explanation:
A chloroplast has stopped producing ATP and NADPH. Which of the following is most likely causing this?
Answer:
Krebs cycle
Explanation:
Krebs cycle is the second phase of cellular respiration, it occurs in the mitochondrial matrix and generates a pool of chemical energy (ATP, NADH, and FADH2) from the oxidation of pyruvate, the end product of glycolysis. Pyruvate is transported into the mitochondria and loses carbon dioxide to form acetyl-CoA, a 2-carbon molecule.

Birds are introduced to an environment, and they prey on light-colored spiders. Over generations, more dark-colored spiders are observed in the population. What process is most likely occurring?
Answer:
Birds are introduced to an environment through evolution and can prey on light-colored spiders to survive. Over generations they can be observed in the population during the process of a food chain. Furthermore, the process can be through biology and chemistry. The one at the top of the food chain (birds) can eat the ones at the bottom of the food chain (light-colored spiders).
Explanation:
The process that is occurring is called NATURAL SELECTION.
Natural selection is the main evolutionary force acting on natural populations.Natural selection refers to the differential survival and reproduction of organisms depending on the environment in which these organisms live.In this case, dark-colored spiders are better adapted and therefore they will have more chances to survive and reproduce.In conclusion, the process that is occurring is called NATURAL SELECTION.

Which of the following statements correctly describe(s) the relationships shown on the graph? Statement 1: At high light intensity an increase in carbon dioxide concentration from zero to low causes an increase in the rate of photosynthesis. Statement 2: At high light intensity an increase in carbon dioxide concentration from high to very high does not increase the rate of photosynthesis. Statement 3: At low carbon dioxide concentration an increase in light intensity from low to high does not change the rate of photosynthesis.
Answer:
statement one
Explanation:
because increase in light intensity is increasing the rate of photosynthesis

6. Challenge: Based on the weathering patterns, guess the rock type shown in each photo. (Can anyone confirm or deny these answers?)
Answer:
A. = Shale
B = Granite
C = Sandstone
D = Limestone
Explanation:
Based on the weathering patterns, the rock type shown in each photo can be concluded to be as
A. = Shale: this is a form.of sedimentary rocks. It is formed from finely textured materials. Such as clay, quartz, and calcite minerals
B = Granite: this is derived from igneous rock. It has coarse texture features.
C = Sandstone: it is formed by a sand-sized grain of natural earth materials that form together
D = Limestone: it is also a form of sedimentary rock. It contains a large quantity of calcium carbonate it is formed from materials such as ancient corals and skeleton.
Weathering is the process of removal and breaking down of the rocks into soils and minerals and is four types such as physical, chemical, and biological. The weather is both an internal and external process.
Based on the images given, A represents shale, B is granite C is sandstone and D is limestone. The shale is a fine-grained clastic sedimentary rock and is ford by mud. Granite is a coarse-grained intrusive igneous rock. Sandstone is made from sand-sized silicate grains. While limestone is made from calcium calcite that is carbonate sedimentary rock. Hence confirmed.Learn more about the weathering patterns, guess the rock type.

A group of students wants to study the rate of photosynthesis under various conditions. They use a blender to mechanically disrupt the thylakoid membranes of chloroplasts from an algae sample The liquid
mixture is added to test-tubes, and 5 drops of DPIP solution is added to each tube. One set of tubes is placed in direct sunlight, another is placed in indirect sunlight, and a third is placed under an infrared heat
lamp. One test-tube contains only water and 5 drops of DPIP (control). The students check the color of the liquid in the tubes every 15 minutes for a period of 1 hour. They record their observations in a table

А
The rate of photosynthesis under indirect sunlight is slower than in infrared light
B
The rate of photosynthesis is greatest for direct sunlight and least for the infrared light.
С
The rate of photosynthesis cannot be determined because the infrared lamp degraded the DPIP
D
The rate of photosynthesis cannot be determined because exposure to direct sunlight degraded the DPIP
Answer:
B
Explanation:
The statement that best explains the result would be that the rate of photosynthesis is greatest for direct sunlight and least for the infrared light.
The DPIP will normally replace and play the role of NADPH in the light reaction of the process of photosynthesis. Hence, it will become colorless as a result of reduction and the rate of photosynthesis can be monitored based on the magnitude of the disappearance of the dark blue color.
It means that the more colorless the liquid in the illustration is, the more the rate of photosynthesis. The color change moved from dark blue to clear colorless under direct sunlight, from dark blue to nearly colorless under indirect sunlight, and from dark blue to slightly lighter under the infrared light. This clearly indicates that the rate of photosynthesis is highest under direct sunlight and lowest under infrared light with the indirect sunlight having an intermediate rate.
The correct option is B.
When an organism is exposed to a limited quantity of oxygen, the cell's mitochondria will stop cellular respiration involving the Krebs cycle and enter the process of fermentation to survive. What conclusion can be drawn regarding an organism's ability to undergo fermentation?
Answer: Fermentation must create a net gain of ATP.
Explanation: Fermentation is a process in which organisms such as yeast, bacteria convert sugar into an alcohol or an acid. It is an anaerobic process because it does not require oxygen. The fermentation process is completed in the cytoplasm with a net gain of 2ATP during the glycolysis. Although it is a common pathway it is not the only method used by organisms produce ATP anaerobically.
