Answer:
The plant cell is said to have become "turgid" i.e. swollen and hard.
brainliest plz :'D
Explanation:
Final answer:
When a plant is placed in pure distilled water, its cells will swell due to the hypotonic nature of distilled water resulting in turgidity, which is beneficial for maintaining plant structure.
Explanation:
When a plant is placed in pure distilled water, its cells will swell and become turgid. This is because pure distilled water is a hypotonic solution relative to the cells of the plant. In a hypotonic environment, water enters the cell due to osmosis, increasing the water volume inside the cell's central vacuole, resulting in turgor pressure which stiffens the cell walls. Unlike animal cells, plant cells are equipped with rigid cell walls that provide protection against bursting. When a plant cell is in a hypotonic solution, it will not burst but will instead become turgid, which is the ideal state for plant cells as it helps maintain the structure of the plant.
In contrast, when plant cells are placed in a hypertonic solution like sea water, they undergo plasmolysis, where water diffuses out of the cells causing them to shrink and the plant to wilt.
LO 5-3 How does the nervous
system communicate electrica
and chemical messages from
one part to another?
Final answer:
The nervous system communicates through an electrochemical process, where electrical signals within neurons are combined with chemical signals via neurotransmitters across synapses, enabling efficient transmission of messages throughout the body.
Explanation:
How the Nervous System Communicates
The nervous system uses an intricate electrochemical process to communicate messages across different parts of the body. This complex process involves both electrical signals within neurons and chemical messengers known as neurotransmitters to transmit information between neurons. Let's break this process down into understandable parts:
Electrical Signaling: Within a neuron, an electrical signal travels from the dendrites, through the cell body (soma), and along the axon to the nerve terminal.Chemical Signaling: Once the electrical signal reaches the axon's end, it triggers the release of neurotransmitters into the synapse, the gap between neurons. These chemical messengers then bind to receptor sites on the adjacent neuron, effectively transmitting the signal across the gap.This combination of electrical and chemical signaling allows for fast and efficient communication throughout the nervous system, enabling response to stimuli and coordination of activities.Through this powerful electrochemical mechanism, our nervous system controls everything from simple reflexes to complex thoughts and emotions.

Explanation:
Because plants don’t have interior or exterior skeletons they rely on their cells walls to give them support . Did you see evidence of the cells structure in plants ? How was it different from animal cells
Answer:
Plant cells have cell walls and this is how they differ from animal cells because animal cells do not have cell walls. Animals don't need cell walls because they have skeletons that help stabilize their bodies. The cell wall provides structure and strength to the cell. I saw evidence once when I was in a biology class.
I did see evidence of the cell structure in plants. Plant cells have a cell wall, which is a rigid structure that surrounds the cell membrane.
How are plant and animal cells different ?The cell wall is made up of cellulose, a complex carbohydrate that gives plants their strength and rigidity. Animal cells do not have cell walls. The cell wall provides support and protection for the cell.
Plant cells have chloroplasts, which are organelles that contain chlorophyll. Chlorophyll is a green pigment that helps plants to photosynthesize. Animal cells do not have chloroplasts. Plant cells have a large central vacuole, which stores water and other nutrients. Animal cells do not have a central vacuole.

Sammy is not alive, the reason behind this is because the word was. If he were still alive, it would be is. Hope this helps! also can i please have brainliest? x
Explanation:
Yes, Sammy is alive. Losing his hand and getting an artificial one doesn't change his life status. Vital organs and biological processes determine life, not limb loss.
Yes, Sammy is alive. The incident of losing his hand and replacing it with an artificial hand does not necessarily mean he is no longer alive. The loss of a body part does not define one's life status. Being alive is determined by the functioning of vital organs and biological processes, which are not affected by the loss of a single limb.
Despite the accident, Sammy's heart is still beating, he can breathe, and his brain is functioning. The artificial hand enhances his quality of life and functionality, but it does not alter his life status. As long as his essential biological functions persist, he remains alive.

Identify the parts of the atom that are labeled in the
diagram.
Label A:
Label B:
Answer:
Label A: Nucleus
Label B: electron cloud
Explanation:
Without the precise diagram, Label A might refer to the central atom or the atomic number, and Label B could refer to surrounding atoms or the mass number. These labels generally correspond to specific parts of an atom or molecule, which include the nucleus and electrons in the context of atomic structure.
Explanation:The question appears to be related to the structure of the atom and its components. Although the exact diagram for Label A and Label B is not provided, based on the provided references, we can infer that Label A may refer to the central atom in a molecule, while Label B could be addressing the atoms surrounding the central atom. Moreover, in the context of atomic structure, Label A might signify the atomic number, and Label B might represent the mass number, as indicated in reference to Figure 1.8.3 which states that the atom's symbol includes the atomic number and mass number.
In atomic physics, key parts of the atom typically include the nucleus (comprised of protons and neutrons) and the electrons that orbit around it. The nucleus is the dense center of the atom, containing most of the atom's mass, while the electrons are subatomic particles with a negative charge that move around the nucleus in what are known as electron clouds or shells.
If the diagram provided to the student was similar to the one described in the references, Label A and Label B would likely be pointing to specific parts of the atom or to elements in a compound or molecule depending on the context given within the diagram.

O
C. Strombolian
O
D. Plinian
Answer:
B.Hawaiian
Explanation:
Answer:. Hawaiian
Explanation:
Here is why. Among the options listed, the Hawaiian volcanic eruption type is the least violent. Hawaiian eruptions are characterized by relatively fluid basaltic lava that flows relatively gently from the volcano's vent. The lava often travels in streams or rivers and can create impressive lava fountains, but the explosions and ash clouds associated with Hawaiian eruptions are generally less intense compared to other types of eruptions like Plinian, Pelean, or Strombolian eruptions.
The “cause” for something to happen is the:
A. Effect
B. Feedback
C. Response
D. Stimulus
Answer:
d stimulus
Explanation:
The stimulus is what triggers an event, or its "cause". Therefore, option (D) is correct.
A stimulus is an internal or external force that causes an organism or system to respond or react. A physical event, an environmental change, or a particular input may start a series of events that result in an outcome or reaction.
In order to trigger a biological, physiological, or behavioural response in living things or a reaction in non-living systems, the stimulus serves as a catalyst. It acts as the catalyst for a chain of events that, depending on the situation, have the potential to produce an impact, feedback, or reaction.
