Water potential is the tendency of water to move from one place to another. Pumpkin cores were placed in sucrose solutions at 22°C and normal atmospheric pressure. The following data were gathered.
Individual Data for Pumpkin Cores
Contents in beakers Initial mass Final mass Percentage
change in mass
Water 29.15 32.12
0.2 M sucrose 28.45 29.41
0.4 M sucrose 30.92 29.84
0.6 M sucrose 29.25 27.14
0.8 M sucrose 32.09 28.54
1.0 M sucrose 31.67 27.58
a) Complete the above table
b) Graph the percentage change in mass. Label both the x and y axes.
c) Using the graph, determine the molar concentration of the pumpkin cores and explain how it is related to pressure potential.
Answer:
For part A this is how you solve it:
Final mass-Initial mass=x. Then divide x/initial mass to get final percentage
32.12-29.15=2.97. 2.97/29.15= 10.19%
29.41-28.45=0.96. 0.96/28.46= 3.37%
Etc.

Vascular plants, such as pine trees, are usually much larger than non-vascular plants, such as mosses. Which of the following is the best explanation for this difference?
Question 9 options:
Vascular plants can only transport watera from one cell to the next cell.
Non-vascular plants can transport water and food in tube like structures called xylem and phloem.
Vascular plants can transport water and food in tube like structures called xylem and phloem.
Non-vascular plants transport water only in their roots.
Answer:C.
Explanation:
The main reason for the size difference between a moss plant and vascular plants is that vascular plants can transport water in a tube structure called xylem and phloem.
Vascular plants contains tissues that makes up their vascular bundles.
The xylem is used to transport water in plants.
Phloem is used to transport food in plants.
Vascular plants differs from non-plants by possessing this structure.
As the grow they add up more these.
this is an evolutionary edge over the non-vascular plants.

Which description distinguishes eukaryotes from prokaryotes
Answer:
Explanation:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
Prokaryotes only contain a single circular chromosome and lack a nucleus and membrane-bound organelles. In contrast, eukaryotes have numerous linear chromosomes and a nucleus.
Organisms called eukaryotes have intricate cellular structures. Their cells are distinguished by the presence of a genuine nucleus, which contains the DNA that serves as the genetic code. The nuclear envelope, a double membrane that encloses the nucleus, is made up of numerous organelles including the Golgi apparatus, endoplasmic reticulum, and mitochondria. These organelles are in charge of carrying out numerous metabolic processes and carrying out specialised tasks required for the survival of the cell. On the other hand, prokaryotes are straightforward organisms devoid of a nucleus and organelles that are bound to membranes. Their cells have a single nucleoid, a circular fragment of DNA that floats freely in the cytoplasm and gives them some control over their genetic makeup.

Explain why the energy that is stored in the chemical bonds of a
molecule is not destroyed when that molecule is broken down to smaller
molecules.
Answer:
Because the atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.
Explanation:
Thats why the energy that is stored in the chemical bond of a molecule is not destroyed when that molecule is broken down to smaller molecules
The atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.
What is Chemical bond?
The energy that is stored in the chemical bond of a molecule is not destroyed when that molecule is broken down to smaller molecules.
When atoms are attracted to each other and join together to form a molecule, we call the connection between each atom a chemical bond. The bond “holds together” the atoms in the molecule, ion, or crystal.
Chemical bonding is the attraction between two or more atoms that allows them to be able to form a stable chemical compound. The specific nature of a chemical bond can vary, but the most commonly known are covalent and ionic bonds.
Therefore, The atoms are held together by the interactions of electrons in their valence shells. Separating them therefore makes them less stable.

Hey! an organ system is cells all grouped together that have the same function.
Explanation:
In animals, organ systems are all of organs put together. Like the digestive system, muscular system, and nervous system.
In plants, its normally how the cells work together. Like cytoplasm and cell walls.
Several organs that collectively perform a single function form an organ system.

Digestive System:It is also called Gastrointestinal(GI) System. The GI system starts from mouth and ends at anus. All the organs between and including the mouth and anus comes under GI system.
The GI system intakes food and breaks it down into small and diffusable nutrients and excretes the solid waste products. One of the most important purposes of food is to serve as cellular fuel. Also, carbohydrates, proteins, and fats can all be used by our cells as sources of the energy that they need to stay alive.

If infection primarily involves the outermost layers of adult amphibian skin, and if the chytrids use the skin as their sole source of nutrition, then which term best applies to the chytrids
Explanation:
Amphibian populations worldwide have been in decline for many decades now. The spread of the chytrid fungus, Batrachochytrium dendrobatidis, appears to be a major proportion of the decline (Bd). Chytrid sporangia occurs inside infected animals' epidermal cells, animals that subsequently exhibit regions of sloughed skin. They may also belethargic, expressed by the inability to escape and the inability to run. Usually, the infection takes four to five days, at the end of which zoospores are released into the atmosphere from sporangia. Mortality rates of some amphibian populations exceed 100 percent; other species appear to be able to survive the infection.
