Answer:
It saves time
Explanation:
You don't have to draw unnecessary details for complex structures
Line drawings will save the scientist time instead of Lewis structure.
what is Lewis structure ?It is a representation of a molecule structurally, where dots are used to show the position of electron around the atoms and lines represent covalent bonds between atoms.
Lewis structure is used to identify the lone pair of electron in molecules which help to determine chemical bond formation.
Lewis structures is used for the molecule having covalent bonds and for coordination compounds.
It can be also known as Lewis dot diagrams, electron dot diagrams, Lewis dot formulas etc.
This structure are based on the octet rule and describe chemical bonding, do not describe aromaticity, magnetic behavior accurately.

Answer:
osmosis, diffusion, facillitated diffusion!
Explanation:
jus did it
Diffusion, osmosis, facilitated diffusion are the passive transport.
What is osmosis ?The process in which solvent molecules pass from a lower concentration region to a higher concentration solution through a semipermeable membrane called as osmosis.
It is a passive transport as no external energy is needed.
Osmosis, like a diffusion not require the input of energy and it moves water down or against the concentration gradient.
When a living plant cell kept in a sugar or salt solution, water diffuses from the cell sap out through the cell membrane called as exosmosis.
The cell causes shrinkage of the protoplasm due to water loss, where the cell undergo a condition called as plasmolysis or necrosis.
When the plasmolyzed cell is placed in distilled water, the cell regains it’s turgidity and also the original shape and size by a process called endosmosis.

Coral and algae need light in order for photosynthesis to take place. How to depth in the availability of light contribute to have these organisms are distributed on the ocean floor
Answer:
Only blue light reaches deep into the ocean.
Explanation:
Coral reefs exist in waters less than 50 m to 2000 m deep while Red algae have been found living in depths of over 500 feet because both coral reefs and red algae needs blue light for photosynthesis. In the deep sea or ocean, only short wavelength such as blue light reaches deep in the ocean floor while long wavelength light such as red unable to reach so that's why both coral reefs and red algae present and distributed on the ocean floor.

Answer:
Hypothesis
- ideally should be tested by an experiment in which only one variable is changed
- may still be useful even when evidence does not support it
- tentative scientific explanation that can be tested by further observation or by experiment
Scientific Law
- concise, specific descriptions of how some aspects of the natural world are expected to behave in a certain situation
- well-tested explanation for a range of phenomena
Theory
- highly reliable scientific explanation of events in the natural world that unifies many repeated observations
Explanation:
A hypothesis is an assumption that intends to explain a phenomenon, while a scientific hypothesis is tested by using the scientific method. The development of a testable hypothesis is the first step during the scientific method. Moreover, a scientific theory is a more coherent and stronger explanation of the natural world, which has been confirmed by experimental and/or observational procedures. Finally, a scientific law is a solid statement funded on repeated observational/experimental methods. A scientific law can be used not only for understanding but also for predicting different phenomena from the real world.

2. Which determines the identity of an element
A. its mass number
B. the charge of the atom
C. the number of its neutrons
D. the number of its protons
The identity of an element is primarily determined by: D. The number of its protons.
The identity of an elementThe number of protons in an atom's nucleus is known as its atomic number. Each element on the periodic table has a unique atomic number, which corresponds to the number of protons in the nucleus of its atoms. For example, hydrogen has an atomic number of 1 because it has one proton, while carbon has an atomic number of 6 because it has six protons.
The atomic number is crucial in defining the identity of an element because it distinguishes one element from another.
Hence option d is correct

Write a hypothesis that explains why you think leaves change color in the fall.
Fall brilliance of the leaves is a result of chlorophyll decomposition, which causes the green color to disappear and the yellow to orange hues to appear.
What is chlorophyll brake down hypothesis?If plants degrade the chlorophyll and move it out of their leaf before the leaves fall, they can save energy.
Plants are capable of reabsorbing the substances that go into making chlorophyll. However, due to changes in temperature and daylight hours in the fall, the leaves stop generating food.
As a result, during the summer, chlorophyll is continuously degraded and rebuilt in tree leaves.
Therefore, chlorophyll brake down hypothesis that explains why you think leaves change color in the fall.
