Answer:
Photosynthesis 02.07RITA RIFFI
sunlight is made in to a chemical energy using chlorophyll. Then uses energy to convert co2 and water in to glucose.
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a type of sugar) and oxygen. This process occurs in the chloroplasts of plant cells.
Here is a step-by-step explanation of the process of photosynthesis:
1. Light Absorption: Chlorophyll, a pigment found in chloroplasts, absorbs sunlight. This light energy is essential for photosynthesis to occur.
2. Conversion of Light Energy: The absorbed light energy is used to power a series of chemical reactions that convert carbon dioxide and water into glucose. This process is called the light-dependent reaction.
3. Production of ATP and NADPH: During the light-dependent reaction, energy is stored in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules act as energy carriers in the next step of photosynthesis.
4. Carbon Fixation: The ATP and NADPH produced in the light-dependent reaction are used in the Calvin cycle, also known as the light-independent reaction or the dark reaction. In this step, carbon dioxide is converted into glucose using the energy stored in ATP and NADPH.
5. Release of Oxygen: As a byproduct of photosynthesis, oxygen gas is released into the atmosphere. This oxygen is essential for the survival of many organisms, including humans.
Overall, photosynthesis plays a crucial role in the Earth's ecosystem by providing oxygen and producing food for organisms. It is an essential process that sustains life on our planet.

One student did an experiment on the rock cycle. The steps of the experiment are shown below.
• Half fill a glass bottle with pieces of granite.
• Pour dilute acid into the bottle to submerge all the granite pieces.
• After a week pour off the acid.
Shake the bottle vigorously for two minutes.
• Filter the contents of the bottle into a dish of water.
• Leave the dish undisturbed for an hour.
• Put two heavy weights on the material in the dish for a week.
What does the student's experiment most likely demonstrate about the rock cycle?
A) Pressure can cause melting of rocks to form igneous rocks.
B) Pressure can crystallize dissolved rocks to form sedimentary rocks.
C) A series of steps can cause weathering of rocks to form sedimentary rocks.
D) A series of steps can transform rocks into magma which cools to form igneous rocks.
What do we call the cells in phloem that are alive at maturity but lose almost all their organelles?
A. Sieve- tube
B. Tracheid's
Answer:
Sieve-tube
Explanation:
Sieve elements are thin-walled cells that are alive at maturity, although the protoplast is greatly changed, and they generally lack nuclei. Sieve elements are elongated and function as the basic photosynthate-conducting cell type in the phloem of vascular plants.

(4 pts) Please read the following experiment and answer the questions below.
Mr. Bailey decides to do an experiment to see if different types of popcorn pop faster in the
microwave. The TV commercials say that Popalicious is the fastest popping popcorn in the
world. Mr. Bailey's hypothesis was, "If I pop Jiffy Pop, Popalicious, and Pop-Tastic popcorn in a
microwave, then the Popalicious will pop faster because the commercial says so." He takes
Jiffy Pop, Popalicious, and Pop-Tastic and places them each in the microwave for 2 minutes.
After two minutes is up, he counts the number of POPPED kernels in the bag. After three trials,
Jiffy Pop had an average of 256 popped kernels, Popalicious had an average of 341 popped
kernels, and Pop-Tastic had an average of 357 popped kernels.

As you move from right to left on the periodic table, what happens to the number of protons and neutrons in atoms?
As you move across a period, the atomic mass increases because the atomic number also increases. When the atomic number increases, this means that there are more protons and neutrons that add to the atomic mass of an atom. The atomic mass for any given atom mainly comes from the mass of the protons and neutrons

Organisms that are not able to make their own food/sugar/carbohydrates are not called autotrophs but what ?
HETEROTROPHS
Explanation:
Autotrophs are any organisms that are capable of producing their own food. For most, this is achieved by using light energy, water and carbon dioxide. Heterotrophs cannot produce they have to absorb.

Which aspect is an example of structural adaptation?
The bill lengths of carnivores are an example of a structural adaptation. Therefore, option (4) is correct.
Structural adaptations are physical features or characteristics of an organism that have evolved to help them survive and thrive in their environment. In this case, the bill lengths of carnivores (meat-eating animals) have evolved to suit their specific feeding habits and prey types.
For example, some carnivores have long, sharp bills for tearing apart their prey, while others may have shorter, more robust bills for crushing shells or consuming insects. The specific bill length is a structural adaptation that aids in obtaining and consuming food efficiently, which is crucial for the carnivore's survival and reproductive success in its ecological niche. Therefore, option (4) is correct.

Usually, the three ecological pyramids look similar in shape. Sometimes, a pyramid of numbers does not have the usual pyramid shape, even though the other two pyramids for the same ecosystem do. We reviewed this twice in class. Explain the reason that sometimes a “pyramid” of numbers does not have a pyramid shape, and be able to draw the shape of this “pyramid”.
The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. the available energy from one trophic level to another increases b. energy is lost at each level as heat, which increases randomization c. the amount of biomass decreases from one trophic level to another d. the available energy at each level may either increase or decrease, creating randomization please select the best answer from the choices provided a b c d
The energy in the pyramid is entropy as it helps in the energy transfer energy from the trophic level the correct option is energy is misplaced at every tropic stage as warmness and serves to growth entropy.
The strength glide via meals chain and meals webs comply with the second regulation of thermodynamics. At every tropic stage, the handiest 10% strength is surpassed in the following stage and relaxation 90% is misplaced as warmness. Therefore, strength switch via meals chains continually finally ends up with lesser usable strength. The strength misplaced in the surroundings in the shape of warmth has a tendency to grow the entropy of the system. The better the tropic stage, the greater the warmth to be had to growth entropy.What is an energy pyramid?
A strength pyramid additionally called atrophic or ecological pyramid is a graphical illustration of the strength located in the trophic degrees of an ecosystem. The backside and biggest stage of the pyramid is the manufacturers and includes the biggest quantity of strength.
Thus it is clear that energy is lost at each level as heat, which increases randomization.
