Why do scientists think that cuttlefish
have the biggest brain to body ratio of all
invertebrates (animals without a spine)?
Answer:
Due to its high intelligence.
Explanation:
Scientists think that cuttlefish have the biggest brain to body ratio of all invertebrates that allows it to sense sight, smell, and sound that comes to it in the form of pressure waves. Due to this big brain, cuttlefish are very intelligent so due to its intelligence the scientists thinks that cuttlefish has the biggest brain as compared to other big vertebrates such as octopus.

B.
Mitochondria produce energy from food, while chloroplasts produce food from the Sun’s energy.
C.
In plants, mitochondria provide energy in non-green cells, while chloroplasts provide energy to cells in parts of the plant that are green.
D.
Mitochondria provide energy in the night, while chloroplasts provide energy in the day.
E.
Mitochondria provide energy from food synthesized by organelles other than chloroplasts, while chloroplasts provide energy through photosynthesis using the Sun’s energy.
Answer:
The answer is option E- Mitochondria provide energy from food synthesized by organelles other than chloroplasts, while chloroplasts provide energy through photosynthesis using the Sun’s energy.Explanation:
Electron transport from complex I to complex IV pumps more protons than transport from complex II to complex IV.
With this in mind, which will produce more ATP
A. Transport from complex I produces more ATP.
B. Transport from complex II produces more ATP.
C. Both produce the same amount of ATP.
Answer:
A
Explanation:
ATP synthase uses a proton gradient to make ATP. Since transport from complex I creates a larger proton gradient, it also produces more ATP.
Electron transport from complex I produces more ATP.
ELECTRON TRANSPORT CHAIN:
The electron transport chain, ETC, is the third and last stage of aerobic cellular respiration. It produces the highest molecules of ATP in cellular respiration. The ETC involves the transfer of electrons to series of molecules in order to create an electrochemical gradient needed for ATP synthesis. The electron transport chain is made up of four complexes namely: Complex I, II, III and IV. NADH and FADH2 produced in the Krebs cycle are the electron carriers. Complex I pumps more hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space. Since the pumped is directly related to the number of ATP molecules, complex I will produce more ATP molecules.Learn more: https://brainly.com/question/442662?referrer=searchResults
explain how the equilibrium price is determined
Answer:
The equilibrium price is the price at which the quantity demanded equals the quantity supplied. It is determined by the intersection of the demand and supply curves. .
A decrease in demand will cause the equilibrium price to fall; quantity supplied will decrease.

Write any three differences between mass and weight
please its aurgent fast
Answer:
See explanation
Explanation:
There are a number of differences between mass and weight, they include;
Mass is a scalar quantity whereas weight is a vector quantity.
Mass is dependent on the quantity of matter present in a body whereas weight depends on the acceleration due to gravity in a particular location on the earths surface.
The SI unit of mass is kilogram whereas the SI unit of weight is Newton.
What are the three main classifications that describe galaxies? By what one visible
characteristic do scientists categorize galaxies?
Answer:
Spiral Galaxies, Elliptical Galaxies & Irregular Galaxies
Explanation:
How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.

16. In which of the following situations are the phenotypes of F2 offspring expected to follow
the ratio of 9:3:3:1?
a. monohybrid cross for two unlinked traits
b. a monohybrid cross for two closely linked traits
c. a dihybrid cross for two unlinked traits
d. a dihybrid cross for two closely linked traits
Answer:
C
Explanation:
The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.
There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.
A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.
Hence, the correct option is C.

Explain how an organ and organelles are related
Answer:
Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells.
Organelles are microscopic subunits that carry out certain tasks within individual cells, whereas organs are distinct body sections that carry out specialized tasks for the human body.
What is the relation between organ and organelles?Literally, the phrase refers to “tiny organs.” Organelles provide specialized functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization in the body, going from the simplest to the most complex.
Like an organ in the body, an organelle is a subcellular structure that performs one or more particular functions for the cell.
Therefore, organ and organelles differ in their functioning.

Answer:
Star A
Explanation:
If you look directly at the diagram, the dwarf stars are labeled under 'A' and are the least in mass and temperature.
Being the smallest and coldest, dwarf stars most commonly have red coloration, which would make them the obvious choice.
Star A which is a dwarf star has the coldest temperature, and therefore is a red star since red stars are the coldest stars.
What are stars?Stars are a large self-luminous bodies whichbpriducw large amounts of heat energy and light energy as a result of the nuclear reactions occurring within them.
Stars have different colors and different sizes.
Red stars are the coldest stars and also the least massive.
From the chart, Star A which is a dwarf star has the coldest temperature, and therefore is a red star.
