Answer:
Density = 0.4g/cm³
Explanation:
Given
Mass = 12 g
Length = 3 cm
Required
Determine the density.
To calculate density, we need volume.
Volume of a cube is:
Volume = Length ³
Hence:
Volume = (3cm)³
Volume = 27cm³
Density = Mass/Volume
Density = 12/27
Density = 0.4g/cm³ --- Approximated

What would be the role of the genetic material found in the organelles?
Please give me the brainiest. It would make my day!
Answer:
Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
Photosynthesis produces chemical energy and Cellular Respiration uses chemical energy. What type of chemical energy do they both use?
A. protein
B. sunlight
C. food
D. glucose
Answer:
Photosynthesis uses energy from the sun in terms of sunlight and cellular respiration uses ATP energy.
Photosynthesis uses energy from the sun and cellular respiration uses glucose to get ATP energy. Thus option B and D are correct.
what are the factors affecting photosynthesis ?
The process in which autotrophic plants use light energy from sun and convert it into chemical energy, and prepare their food in the form of glucose called as photosynthesis.
This chemical energy is created from water and carbon dioxide and stored as a sugar molecule, it occur in chloroplasts which has three pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll.
various factors influence photosynthesis like increase in light intensity causes higher rate of photosynthesis, Higher concentration of carbon dioxide increases the rate of photosynthesis, Temperature range between 25° to 35° C optimum for photosynthesis,
Thus option B and D are correct.

answer the following questions regarding the organism that the product is derived from (reasonable guesses or
speculation is ok):
1. What is the organism?
2. Where does the organism live?
3. Briefly characterize the ecosystem that the organism lives in.
4. Provide one example of how the organism depends on another organism.
5. What are some threats to the organism in the ecosystem?
Speculate on how your life would be affected if the organism became extinct.
Answer:
1. An organism is a individual animal, plant, or single-celled life form.
2. Habitat, place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment. Like a forest, lake, coral reef, desert, towns or cities.
3. An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors are animals, trees, plants, and abiotic factors are things that have never been alive. So rock rivers, ponds, man made objects.
4. When a organism depends on another is called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism: both partners benefit. An example of mutualism involves goby fish and shrimp. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone.
5. Pollution(water&air), deforestation, UV Radiation, invasive species.
If an organism went extinct the next generation won't ever be able to see those organisms. If an organism we eat went extinct we would have one less food source which is something that really does not need to happen in today world.

I chose the product cotton pants. The responses are:
Cotton plant
Southeastern North America
The plant lives in soil in an agricultural field.
The cotton plant requires bees for pollination.
The plant may be threatened by diseases such as cotton leaf curl disease, pests such as aphids, and drought.
If cotton became extinct, my pants would have to be made of some other material, such as linen or wool, which would feel quite different. This would be a big adjustment for me because I am used to wearing cotton pants almost every day.

O As bacteria and viruses are destroyed by leukocytes, they release bursts of heat
The bright red pigment of blood warms the internal proteins
O Blood pressure causes formed elements to bump into sides of blood vessels, resulting in friction and resistance
The excess mitochondria in red blood cells produce extra ATP
whats the difference between acid , bases and buffers?
Please select me as brainiest. It would make my day.
Answer:
A basic solution will have a pH above 7.0, while an acidic solution will have a pH below 7.0. Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H+ions or OH– ions, thereby maintaining an overall steady pH in the solution.
What does a flow chart look like?
Answer:
a flow chart is a graphical or symbolic representation of a process. each step in the process is represented by a different symbol and contains a short description of the process step. the flowchart symbols are linked together with Arrow showing the process flow directions.

1. In passive transport, what direction do molecules move?
2. In active transport, what direction do molecules move?
Answer:
In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.
In active transport, the particles move across a cell membrane from a lower concentration to a higher concentration. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient.
Explanation:
The transfer of molecules from higher concentrations to lower concentrations is an example of passive transport, which does not require any amount of energy.
The movement of molecules from a lower concentration to a higher concentration is referred to as active transport. Active transport requires the application of energy.

What is an example of dissociation?
A. vegetable oil dissolving in water
B. table salt dissolving in water
C. hydrogen chloride dissolving in water
D. table sugar dissolving in water
Answer:
I'll say B cause the Nacl ion breaks down and get surrounded by hydrogen and hydroxyl ion
Table salt dissolving in water is the example of dissociation.
What do you mean by dissociation?Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner.
Moreover, the dissociation of water is an equilibrium reaction in which one water molecule donates its proton to another water molecule.
Salts that are soluble in water dissociate into their ions and are electrolytes. Salts that are insoluble or only slightly soluble in water form very few ions in solution and are nonelectrolytes or weak electrolytes.
