Answer:
A: osmosis. The egg first expanded because it was placed in a hypertonic solution (sugar water), causing the water to exit the egg to balance the higher concentration of solute outside of the egg. Placing it in fresh water creates a hypotonic environment, thereby causing water to rush back in.

It states that all cells have a nucleus
which divides.
С
All cells are bacteria that get made
into eukaryotic cells
B
It states that cells come from
previously existing cells.
D

need to be copied into animal cells
Answer:
when cells are damaged , those cells are replaced by the process called cell division.
this fact support that cells arise from pre existing cells.(omni cellulae e cellulae) is given by Rudolf virchow. thus , he gave final shape to cell theory.
When cells are damaged, new cells are created by cell a process called cell division. The cell theory supports this fact as it states that all cells have a nucleus that divides.
What is the cell theory?All living things are primarily composed of cells, which serve as both the basic structural and organizational units of all living things. According to the biological notion known as "cell theory," all cells are descended from previously existing cells. All living things are composed mostly of cells, which also serve as the fundamental unit of reproduction. The cell theory is based on the following three basic postulates: Every living thing is made up of one or more cells.The fundamental unit of structure and organization in organisms is the cell. New cells are created from pre-existing cells. Theodor Schwann and Matthias Jakob Schleiden are two scientists usually credited with developing or discovering the cell theory. In 1839, Schleiden claimed that every structural element of a plant is composed of cells or is a cell-derived substance. Additionally, he suggested that cells were created through a crystallization process that took place either inside or outside of other cells.

While visiting Wave Rock in Australia, you observe streaks of minerals present on the landform. What natural process most likely caused the streaking?
The answer is deposition
Answer:
Deposition would have most likely caused the streaking.
Explanation:
Deposition is the laying down of sediment carried by wind, water, or ice. Sediment can be transported as pebbles, sand & mud, or as salts dissolved in water. Salts may later be deposited by organic activity or by evaporation.
One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid. This causes the water vapor to change directly into a solid. Another example is the soot that is deposited on the walls of chimneys.

Answer:
probably A, B, or D.
Explanation:
Answer:
14. A Carbon dioxide
15. C glucose
Explanation:
#14 is A, carbon dioxide because cellular respiration releases Carbon dioxide (co2) and H20 (water).
#15 is C, glucose because photosynthesis takes in Co2, h20, and Sunlight and creates sugar (glucose) and oxygen.
The products of photosynthesis are the reactants of cellular respiration and vice versa.

most of the energy an organism consumes is used/converted into
Answer:
converted into
Explanation:
The higher the organism is on the trophic pyramid, the lower the amount of available energy. For example, plants and other autotrophs (primary producers) convert only a fraction of the enormous amount of solar energy they have access to into food energy.

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Explanation:
Grapes are planted in later winter or in early spring seasons and they continue their growth in the summer months. During their growth, the grapes shrink a little during the day and gain in size at night. This phenomenon is due to the grape cells are composed of a hypertonic (concentrated) sugar solution that during the day lost water by osmosis, thereby shrinking the cytoplasm.
Which best explains how scientists confirmed that the moon formed around the same time as Earth?

However the globe would look same due to presence of plate tectonics with a stable climate, mineral and oil deposits, and oceans with a chemical balance.
These plates are mainly 100 km thick, are made up of this crustal layer which continue to float on the warm and thick mantle, and create mountains
These plates are puzzle like matching pieces on the surface of the planet that , the movement of the plates caused by the mantle convection from below the lithosphere.

Heat Transfer discussion based question
Your response needs to be AT LEAST 2 paragraphs.
DISCUSSION QUESTION: How is thermal energy transferred?
Answer: Thermal energy flows from a warmer material to a cooler material. When thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three ways heat is transferred into and through the atmosphere: Radiation, conduction and convection.
Radiation is when energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
