Explain why the water potential of a cell is always less than zero.
The internal water potential of a plant cell is more negative than pure water because of the cytoplasm's high solute content. Because of this difference in water potential water will move from the soil into a plant's root cells via the process of osmosis.

Explanation:
In both zoocentrism and biocentrism, the fundamental unit of moral consideration is the individual animal or plant. True False
Given what we know about zoocentrism and biocentrism we can confirm that the statement made in the question is false.
Zoocentrism and biocentrism are both ethical theories. These can be better described as mindsets, they are a way of thinking for scientists and humans as a whole in regards to the well-being of plants and animals.
Zoocentrism is the belief in which moral consideration is given primarily to animals. This means that animals, or at least some animals, are given moral consideration above all others, their well-being is considered more important. On the other hand, biocentrism is the idea that all living things should warrant consideration, be they plants or animals.

The simplest type of cell transport is _________________, in which molecules move from an area of _______________ concentration to an area of __________ concentration. Diffusion does not use ATP, so it is called _____________ transport. The movement of a solute from an area of low concentration to an area of high concentration requires __________ usage by _________ proteins. This form of transport is referred to as _______________ transport.
low; passive; diffusion; high; carrier; active; ATP.
Answer:
hii
Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. There are different types of diffusion: simple in which the molecule passes directly through the phospholipid bilayer and facilitated which uses the integral membrane proteins as channels.
The simplest type of cell transport is diffusion, in which molecules move from an area of high concentration to an area of low concentration. Diffusion does not use ATP, so it is called passive transport.
The movement of a solute from an area of low concentration to an area of high concentration requires ATP usage by carrier proteins. This form of transport is referred to as active transport.
What is Active transport?Active transport may be defined as a type of transport that occurs against the concentration gradient which is mediated by the carrier proteins.
Metabolic energy in form ATP is required to move ions or molecules against the concentration gradient. This type of transport significantly results in the accumulation of solute one one side of the membrane.
While passive transport does not required any form of metabilic energy to facilitate the migration of ions or molecules. It occurs along the concentration gradient.
Therefore, the processes of active and passive transports are well described above.

define plasma membrane in five words
Answer:
The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is also simply called the cell membrane. The main function of the plasma membrane is to protect the cell from its surrounding environment.
Explanation:
1. Explain how enzymes function as catalysts. 2. Explain the induced fit model of enzymes 3. Provide examples of enzyme-catalyzed reactions in biological systems. 4. Explain the relationship between enzyme structure and function 5. Explain the major modes of the regulation of enzyme activity.
Answer:
1. Enzymes are proteins working as catalysts that speed up processes by reducing the activation energy. They speed up the processes in the cells such that they may occur in fractions of seconds. In the absence of catalysts most biological processes would not occur even during time spans of years.
2. The induced fit model asserts that substrate attaches to an active site and both alter shape slightly, generating an optimum match for catalysis. When an enzyme attaches to its substrate, it creates an enzyme-substrate complex. At the end of the process, the enzyme will always revert to its original condition.
3. The Glycolysis and the Krebs cycle, the processes that are involved in this route are catalyzed by enzymes.
The enzymes of Glycolysis are found outside the mitochondrial surface while the enzymes of Krebs cycle are placed in the matrix of mitochondria except succinate dehydrogenase which is present in the inner membrane of mitochondria.
4. Most enzymes are proteins and consequently their function is unique to their structure. Enzymes function as a catalyst to boost the pace of practically all the chemical events that take place in a biological system.
5. Genetic control, compartmentalization, adjustment of substrate concentration, degradation, changing of environmental parameters like pH, and processing of zymogens are all methods that may be utilized to regulate enzyme activity (induction and repression).

Plants regulating their _____ is the most important function for a plant.
a. ion balance
b. root structure
c. water loss
d. hormone balance
If you answer correctly I will give you brainliest!
Answer:
I believe it is A, it is a crucial part of the process
Plants regulating their ion balance is the most important function for a plant. Thus, the correct option is A.
What is ion balance in plants?Plants also need nutrients for the healthy growth in plants. Carbon dioxide is obtained from air. Inorganic ions in the plants are obtained from the soil where they are dissolved in water in plant body. The three ions which are required in the greatest amounts are nitrate, phosphate, and potassium which are the sources of nitrogen (N), phosphorus (P), and potassium (K), respectively.
The range of unbalance between the positive ions and negative ions in the plant body is called ion balance.
Therefore, the correct option is A.
