Answer:
1. Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
2. Plants obtain water through their roots. Water present in the soil (or air, in the case of air plants) enters the plant through the epidermis of the root. The epidermis is a very thin single layer of cells. The water passes through the membranes of plant cells and also fills the spaces in between the cells.
3. This experiment allows you and your child to talk about the circulatory system and "capillary" action. The small "vessels" in the celery stalks carry the water and color to the leaves, like the way blood travels through your body.
4. A great way to introduce basic science concepts are through fun and visual experiments such as this Celery Experiment. It requires just a few items and is a fun way to teach children about how a plant absorbs water. This process is called Osmosis. We will learn about how plants absorb water using colored water and celery stalks.

27. A form of energy is stored in the bonds
between atoms, What is the name for
this stored energy?
A kinetic energy
B chemical energy
C electrical energy
D electromagnetic energy
A form of energy that is stored in the bonds between atoms of a chemical element is referred to as: B. chemical energy.
A chemical energy can be defined as a form of energy that is stored within the forces of attraction (bonds) that are existing between ions, crystals, atoms or molecules.
In Chemistry, bond energy refers to the amount of chemical energy that is required to break one (1) mole of a particular chemical bond. Also, bond energy is measured in kJ/mol.
In conclusion, a form of energy that is stored in the bonds between atoms of a chemical element typically is referred to as chemical energy.

briefly describe the nebula theory formation of our solar system use the words protostar and protoplanets in your discussion
Answer:
Below!
Explanation:
Currently the best theory is the Nebular Theory. This states that the solar system developed out of an interstellar cloud of dust and gas, called a nebula. This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects. The Nebular Theory would have started with a cloud of gas and dust, most likely left over from a previous supernova. The nebula started to collapse and condense; this collapsing process continued for some time. The Sun-to-be collected most of the mass in the nebula’s center, forming a Protostar.
A protostar is an object in which no nuclear fusion has occurred, unlike a star that is undergoing nuclear fusion. A protostar becomes a star when nuclear fusion begins. Most likely the next step was that the nebula flattened into a disk called the Protoplanetary Disk; planets eventually formed from and in this disk.
Three processes occurred with the nebular collapse:
Temperatures continued to increase The solar nebula spun faster and faster The solar nebula disk flattenedThe orderly motions of the solar system today are a direct result of the solar system’s beginnings in a spinning, flattened cloud of gas and dust.

Changes in water pressure within guard cells cause the cells to open or close the stomata. This response helps the plant maintain homeostasis by
Answer:
reduced water loss
Explanation:
When the water enters the cells, they swell and become bowed. This causes the guard cells to bend away from each other, thereby opening the stomata. Conversely, when guard cells lose potassium ions, water diffuses out of the cells by osmosis.
The response helps the plant maintain homeostasis by regulating water levels that plants lose during transpiration.
What is cellular homeostasis?The expression cellular homeostasis makes reference to the processes by which an organism maintains an internal state of equilibrium.
Cellular homeostasis is fundamental for the survival of the cell and the organism.Cellular homeostasis in this case indicates the mechanism to maintain concentration and gradients used by the plant to carry out metabolic functions.In conclusion, the response helps the plant maintain homeostasis by regulating water levels that plants lose during transpiration.

What is Transpiration ???!
[tex]\huge \bf༆ Answer ༄[/tex]
Transpiration is the the phenomenon which generally occurs in plant, In which the plant looses water in the form of water vapour through stomata.
Two main functions of transpiration ~
It causes transpirational pull that helps in transportation of water from roots to upper portions of the plantIt helps to release excess waterPlant absorb a large quantity of water from the soil by roots . this water reaches to different part of the plant by ascent of sap . the total quantity of water absorbed by plant is more than their requirement. only a fraction of this water from a vapour throw the aerial parts like (stem , leaves , buds , and , flower) of plant which constitute about 95% of total absorbed water . this process is called transpiration .
Transpiration is vital process.This process mainly occur by stomata.Water evaporates in the form of vapour from aerial parts of plant.The loss of water per unit area is more It is regulated processTypes of Transpiration -:
1 Stomatal Transpiration ;
it take place through stomata present on leaves it is also called foliar Transpiration. it constitutes about 80-95% at total Transpiration.2 Cuticular Transpiration;
it take place by cuticle present on the epidermis of plant it is constituted about 5-10% of total transpiration it rate is high in tropical climate and low desert climate.3 Lenticular Transpiration
it take place through lenticles found in Woody stem and in some fruits it constitute 0.1-1% only of total transpiration.how has the change in the human population over time affected the environment
