CAN SOMEONE WHO DID THE CELERY STALK OSMOSIS LAB ANSWER THESE QUESTIONS? 50 POINTS
1. What is osmosis?
2. Celery is composed of millions of plant cells. Do these cells contain any water?
Yes
3. Did the cut celery in step 8 & 9 show any color change that would indicate that the water did enter the celery cells?
4. If you placed the celery into a bottle of colored water that was 35% sugar, would the colored water be seen in the celery? Why or why not? (HINT: Drawing a diagram of this scenario may help – 35% sugar is a very concentrated solution…)
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.

They would be located close to one another.
They would be made up of the same number of elements.
They would all contain exact duplicates of people you know.
They would have the same laws of physics.
The property which would be expected to be true of a parallel universe would be that: They would have the same laws of physics.
Discussion:
A parallel universe by definition is; a separate universe or world that coexists with our known universe but is very different from it. a realm of existence and experience that is fundamentally different from the one that most humans share; a separate reality ultimately.
PS: Plato reflected deeply on the parallel realities, resulting in Platonism, in which the upper reality is perfect while the lower earthly reality is an imperfect shadow of the heavenly.

2. Enzymes that remove a phosphate from proteins
3. Genes that code to destroy a cell if it becomes cancerous
4. Chemicals that slow down the growth of cells
Answer:
If this didn't help then vote me 1 star. Thanks.
Explanation:
Two groups of proteins, called cyclins and cyclin-dependent kinases (Cdks), are responsible for the progress of the cell the. A phosphatase is an enzyme that removes a phosphate group from a protein. Together, these two families of enzymes act to modulate the activities of the proteins in a cell, often in response to external stimuli. Rough the various checkpoints. What genes destroy cancerous cells? The primary function of the p53 gene is to repair or destroy defective cells, thereby controlling potential cancerous cells. This type of gene is called an anti-oncogene or tumor suppressor gene Cancer growth blockers are also called cancer growth inhibitors. They are a type of targeted cancer drug. Our body makes chemicals called growth factors that control cell growth. Cancer growth blockers work by blocking the growth factors that trigger cancer cells to divide and grow. There are many types of cancer growth blockers that work in different ways..

. What is the width of Grandmother’s pelvis, measuring from the pelvic brim? How does her pelvis differ
from Grandfather’s?
The width of Grandmother’s pelvis, measuring from the pelvic brim is 2cm.
The grandmother has a wider pelvis than the grandfather.
The pelvic brim is found at the edge of the pelvic inlet and measures around
2cm. The pelvis in females are always wider than those found in males. This
is due to the adaptation of the female pelvis to child birth.
The pelvis being wider aids the passage of the foetus from the womb and
eases childbirth. This is the reason why the grandmother has a wider pelvis
than the grandfather.

1. What do you notice about the angle of Earth?
2. How do you think this affects the seasons in different hemispheres (halves) of the world?
Answer:
1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.

A euglena is a unicellular organism. Choose an everyday object, such as a car, to use as a model of this euglena. Explain how the parts of the object model how the euglena's cell parts help it stay alive.
Answer:
a car:
Flagellum is a long thread-like structure that works as a navigator or a steering wheel in a car. The thin filament helps an euglena to move forward in any direction it desires.
Cell membrane is like the doors on a car. They regulate what goes in/out. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.
The Nucleus is like the front seat of your car because the driver is in control of what the car does, goes, and what happens inside of the car.
Vacuoles is like the Trunk of your car because you store food, water and other wastes into your trunk, like were all the things go in the vacuoles.
The compression stroke in a car engine is like chloroplasts because it gas to fuel a car the same way chloroplasts convert solar energy in to chemical energy for a cell.
Mitochondrion is like the battery on a car. It gives the motor energy so it can run like the mitochondrion produces energy for the cell.
Eyespot is like a radio, because in some cars, radios pull power directly from the battery from the car battery, and this is why you will get the car radios on while the engine is off
Explanation:
The internal structures found in a typical photosynthetic Euglena are as follows:
Pellicle: A thin, flexible membrane that supports the plasma membrane and helps them to change shape
Plasma Membrane: The selectively permeable membrane that protects the inner content of the cell from the outside environment
Cytoplasm: A jelly-like substance distributed throughout the cell that contains all the cell organelles
Chloroplast: Contains the green pigment chlorophyll that helps them to produce food using sunlight by photosynthesis
Nucleus: A membrane-bound organelle that contains the genetic material, DNA. It also contains a distinct nucleolus that contains RNA and helps the cell to synthesize proteins
Mitochondria: The energy-producing organelle that forms ATP. All cellular activities such as movement and reproduction are performed using the mitochondrial energy source
Ribosomes: Consists of RNA and proteins, and are responsible for producing all cellular proteins
Golgi Apparatus: Manufactures, stores, and transports large molecules such as carbohydrates and proteins within the cell
Endoplasmic Reticulum: The extensive network of membranes that helps to package and transport proteins to different organelles. It is of two types: rough endoplasmic reticulum (RER) – containing ribosomes attached to it; and smooth endoplasmic reticulum (SER) – devoid of ribosomes
Lysosomes: Small membrane-bound organelles filled with hydrolytic enzymes that break down large molecules such as carbohydrates, fats, and proteins
Contractile Vacuole: It maintains the water and salt balance within the cell
Reservoir: The inward pocket present near the base of the flagella where contractile vacuole dispels excess water
Flagellum: A long whip-like structure attached externally to the cell body that helps in cell movement. An amoeba contains two flagella, a short one that does not protrude out of the cell, and a long one that helps in swimming
Eyespot: A region that is highly colored and contains red-colored carotenoid pigments that help in the detection of light. It is sometimes called a stigma
Photoreceptor: Also known as the paraflagellar body, it is the light-sensitive region located near the flagellum that helps to detect light. It also helps in their movement towards and away from light stimuli, a process known as phototaxis
Paramylon: They are stored starch-like carbohydrate granules composed of glucose produced during photosynthesis. Paramylon enables the organism to survive in low-light conditions when photosynthesis is not possible by acting as the food reserve for the cell. When the paramylon is enclosed in a sheath of polysaccharide, it is called the paramylon sheath of pyrenoid.
The flagellum of euglena, can be compared to the wheels of a car, as they are responsible for the movement of both.
What is Euglena?Euglena is a genus of single-celled flagellated algae that can occur either as free cells or in colony form.
What is flagellum?Euglenophytes have the presence of flagella as their main characteristic. They have two flagella, one longer than the other. The smaller flagellum does not emerge from the cell. The larger one is mainly used for locomotion.
With this information we can conclude that euglena has flagella for locomotion just as cars have wheels for locomotion.
