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.

1. Proteins that control the progression of a cell through the cell cycle
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..

Put the stages of the nitrogen cycle in their correct order.
Fixation or volatilization, mineralization, nitrification, immobilization, and denitrification.
The sequence is as follow: Fixation, Nitrification, Assimilation, Ammonification and Dentrification.
What is a nitrogen cycle?The nitrogen cycle is the process by which nitrogen is converted into different chemical forms and moves between the biosphere, atmosphere, and geosphere. The stages of the nitrogen cycle, in order, are:
Nitrogen fixation: Nitrogen gas in the atmosphere is converted into a usable form, such as ammonia or nitrite, by nitrogen-fixing bacteria.
Nitrification: Ammonia or nitrite is converted into nitrate by nitrifying bacteria.
Assimilation: Nitrate is taken up by plants and converted into organic nitrogen compounds, such as proteins and nucleic acids, through the process of assimilation.
Ammonification: Organic nitrogen compounds are broken down by decomposers, such as bacteria and fungi, into ammonia or amino acids.
Denitrification: Ammonia or nitrite is converted back into nitrogen gas by denitrifying bacteria, completing the cycle.

Yifei and Santos are making a diorama on the ecological role of organisms. Yifei wants to show the omnivores eating both plants and other animals, and the herbivores eating other animals. Santos wants to show the omnivores eating only other animals, and the herbivores eating both plants and animals. Who is right?
Answer:
None of them are correct because omnivores, from the root word "Omni" meaning "all", means omnivores eat both plants and animals. Then, herbivores only eat herbs, meaning plants, so both of them are wrong. Animals that eat other animals but not plants are called carnivores.

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.

. 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.

Active transport moves molecules from and to which concentration?
A: high to low
B: low to high
C: low to lower
Option (B) low to high is right Answer
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
We know that, Active transport moves ions and molecules across a membrane against the concentration gradient. It requires energy.
The characteristic features of active transport are:
-The movement of molecules in case of active transport is from lower concentration to higher concentration so it shows uphill transport.
-These have carrier proteins that are highly specific like enzymes for the substances to be carried across the membrane.
-The process of active transport can be inhibited by inhibitors that react with the protein side chains.
-The transport rate reaches its maximum when all the protein carriers are in use or get saturated with the substances to be carried.
The various types of processes that depend on active transport are:
-Absorption of amino acids from the gut.
-Absorption of mineral ions by plant roots.
-Excretion of urea and hydrogen ions by the mammalian kidney.
-Exchange of sodium and potassium ions in nerve cells.
-Filling of the contractile vacuole in amoeba.
The phloem in the leaves of a plant is rich in sugars because of the high rate of active transport.
Additional information :- Some intrinsic protein molecules function as molecular pumps. These permit the cell to go for active transport to accumulate glucose or ions against the concentration gradient. Cells that undergo active transport have abundant mitochondria that provide ATP needed to power active transport.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
