What is the main function
of the following organelles:
Nucleus, mitochondria,
chloroplasts, and vacuoles
Answer:
Nucleus: controls activity and stores DNA
Mitochondria: generates energy for the cell
Chloroplasts: carries out photosynthesis
Vacuoles: stores water and transports
Answer:
Explanation:
Nucleus acts as the brain of a cell, it gives instructions to the organelles on what to do
Mitochondria makes the energy for the cell

Explanation:
bc of like high tide or whatever
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.

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.

If you have a cell with more salt outside the cell, then inside the cell what will happen to the cell?
Answer:
The cell would lose the water inside it causing it to die.
Explanation:
Water in cells moves towards the higher concentration of salt so if there is more on the outside the water would move on the outside causing it to die because it needs water. If it was the opposite and there was more salt inside more water would go inside causing the cell to swell and virtually exploding and diluting parts of our body.

What happens to the enzyme throughout a reaction?
Answer:
Explanation:
The enzyme is free to bind to another substrate and catalyse another reaction. The enzyme is not altered at the end of reaction. As enzyme contains specific shape and charge on its active site, its activity is easily affected by the changes in the surrounding conditions.

What are some jobs that ATP can
help to do?
Answer:
ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.

READ THIS RLLY SHORT PASSAGE AN ANSWER QUESTION FOR BRAINLY!!!!
Sometimes authors use a symbol as an omen, or sign, to foreshadow what is to come. When you see a classic symbol of bad luck or death appear in a story, it’s likely that the author included it on purpose. For example, it’s a common superstition that crossing paths with a black cat will bring bad luck. If a story begins with the main character seeing a black cat run across the street, you can guess that he or she will soon encounter danger. Other examples of superstitious bad omens include the number 13, ravens, crows, bad weather, breaking something, walking under a ladder and opening an umbrella indoors.
However, symbolic omens are not always tied to superstition. Authors sometimes use a seemingly random detail as an omen to indicate that something similar may occur. For example, in the opening paragraph of A Farewell to Arms, Ernest Hemingway writes, “The leaves fell early that year.” This may seem like a minor detail, but it foreshadows a character’s early death later in the story.
Which of these excerpts does not contain a symbolic omen?
A
When Mari opened the curtains, she noticed a raven looking right at her.
B
Mike was excited to get to the dance. He wondered if there would be a live band or a DJ.
C
It was the day the judge would give his verdict. As Paul pulled up to the courthouse, he noticed dark storm clouds gathering above the building.
D
Joon couldn’t wait to show off his guitar skills at the talent show; he’d been practicing for weeks. But when he took out his guitar for one final practice session, one of its strings broke!
Answer:
the answer is B
Explanation:
because A has a raven in it
C has dark storm clouds in it
and D tells a guitar string being broke.
The excerpt that does not contain a symbolic omen is as follows:
Mike was excited to get to the dance. He wondered if there would be a live band or a DJ.Thus, the correct option for this question is B.
What do you mean by Symbolic omen?A Symbolic omen may be defined as a type of natural or man-made ideology that is believed to anticipate the future of an individual by observing some kind of symbols and often signifying the emergence of change.
According to the options given in the question, symbolic omens like a raven which is a large black bird that has an unpleasant voice, a dark room which is the symbol of fear and failure, and a broken guitar are illustrated in options A, C, and D respectively.
Therefore, the correct option for this question is B. This option is opposite to the rest and illustrates the situation of excitement.
