Matter is anything that has mass and takes up space. It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved.
In other words, matter doesn't change into a different substance in a physical change. ... Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

B.Sugar ( Glucose)
Explanation:
I hope this helps!
A compound that is formed as a common product of the process of photosynthesis is sugar (glucose).
What do you mean by Photosynthesis?Photosynthesis may be defined as a process through which plants utilize carbon dioxide and convert it into glucose in the presence of sunlight.
The reactants of photosynthesis are carbon dioxide and water, while the products are glucose and oxygen.
The reaction of photosynthesis is given below:
[tex]6CO_2 + 12H_2O[/tex] → [tex]C_6H_1_2O_6 + 6O_2 + 6H_2O[/tex]

A negative feedback loop is a reaction that causes a decrease in function. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.
What is baseline imbalance?This is simply known as a form of art that pertains to systematic error when producing an intervention groups in any clinical trial. In this type of imbalance, the groups differ in baseline traits due to the fact that the participants were selected or assigned.
There are different ways to balance a load. Why is the figure considered to be an example of a negative feedback system as opposed to a positive feedback system is that The figure shows the correction of an imbalance back to a baseline.
Therefore, A negative feedback loop is a reaction that causes a decrease in function. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

1. The St. Lucie River drains Lake Okeechobee into the Atlantic Ocean.
What is the relationship among the parts of this system?
Answer:
The St Lucie canal serves as an outlet of drainage for the Okeechobee Lake through the St Lucie River and out to the Atlantic Ocean.
Explanation:
The St. Lucie River is an estuary in Florida, in the United States. It was basically a freshwater system before an inlet was dug to provide access directly to the Atlantic Ocean.
Lake Okeechobee is the second largest freshwater lake in the United States. Water flows into the lake from various sources with Kissimmee River being the major source.
Because of the high levels of water in Lake Okeechobee, the St. Lucie canal was constructed in the 1920s. The St. Lucie canal provides a good outlet from the Okeechobee lake, through the St. Lucie River and out to the Atlantic Ocean.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.

8. Outline the process of metaphase, inclusive of the role of microtubules and the centromere.
Answer:
Chromosomes are positioned in the middle of the cell during metaphase.
Explanation:
During metaphase, the centrosomes are at opposite poles or sides of the cell. The spindle apparatus is formed and the nuclear membrane has dissolved. The spindle fibers, also known as microtubules have lined up the chromosomes along the equatorial plate in the middle of the cell so each sister chromatid faces opposite directions. The sister chromatids are still connected by the centromere, and this is the last time they are connected during this division. The centromere is also where kinetochores assemble, and kinetochores are the sites of attachment for microtubules to pull the sister chromatids apart. They are important for the cell to be able to divide.
