If placed in tap water, an animal cell will undergo lysis, whereas a plant cell will not. what accounts for this difference? if placed in tap water, an animal cell will undergo lysis, whereas a plant cell will not. what accounts for this difference? the expulsion of water by the plant cell's central vacuole the relative inelasticity and strength of the plant cell wall the relative impermeability of the plant cell wall to water the fact that plant cells are isotonic to tap water
Answer: The relative in elasticity and strength of the plant cell wall
Explanation:
Animal cell is not made of cellulose but plant cell is. This adds extra protection to the cell.
The cell wall provides protection from the external environment by avoiding the entrance of unnecessary materials through the cell membrane.
The turgor pressure and vacuoles also helps in the movement of water in adequate amount so that the cell does not bursts.

An animal's niche is best described as its specific role and position within an ecosystem, including its interactions with the biotic and abiotic factors of its environment.
What is animal's niche?An animal's niche refers to its specific role and position within an ecosystem. It encompasses the unique set of resources, interactions, and behaviors that allow the animal to survive and reproduce successfully in its habitat.
A niche includes factors such as the type of food an animal eats, the way it obtains its food (for example, hunting or scavenging), its preferred habitat, its reproductive strategies, and its interactions with other organisms, including competition, predation, and symbiosis. Essentially, an animal's niche represents its ecological "job" or functional role within the ecosystem, and different species can coexist in the same habitat by occupying different niches and utilizing different resources.

The major cementing factor(s) in maintaining a long-term relationship is (are) _____.
a. proximity and physical attractiveness
b. similarity
c. proximity
d. physical attractiveness
Final answer:
The major factors in maintaining a long-term relationship center around similarity and shared attributes, which lead to a stronger connection and understanding between partners. The correct answer is b. similarity.
Explanation:
The major cementing factors in maintaining a long-term relationship are not simply proximity and physical attractiveness; rather, they include deeper principles such as similarity and shared values or backgrounds.
While the proximity principle states that we are more likely to form relationships with those we frequently come into contact with, it is similarity in attitudes, interests, and lifestyles that plays a pivotal role in not only the formation but also the maintenance of these relationships.
This concept, known as homophily, explains why people tend to create connections with those who are more like themselves. The correct answer is b. similarity.
After a neuron has reached action potential, the _____ period takes place in which no further action potentials can fire. depolarization polarization hydopolarization repolarization retropolarization
None of the offered answers isn’t correct.
After a neuron has reached action potential, the recovery period takes place in which no further action potentials can fire. The surge of depolarization which travels through the axon of the neuron is known as an action potential. The action potential travels to the axon terminal, where it triggers the release of neurotransmitters. Before the next action potential, the resting membrane potential of the axon must be restored and this is known as the recovery period of the neuron (the neuron cannot transmit another action potential).

Once you have stopped for a school bus, do not pass until the driver signals you to proceed, the red lights stop flashing,
After stopping for a school bus, only proceed when the driver signals and the red lights stop flashing. Safety first.
The message is clear: Once you have stopped for a school bus, do not pass until the driver signals you to proceed, and the red lights stop flashing. Here's why this is so important:
Child Safety: When school bus lights are flashing, it means children are getting on or off the bus. These young pedestrians may not always pay full attention to traffic, so it's vital to create a safe zone around the bus.
Legal Requirement: In many jurisdictions, it is not just a safety measure but a legal requirement to stop for a school bus with flashing red lights. Violating this rule can result in fines, penalties, and even license suspension.
Visibility: The flashing red lights and stop sign on a school bus provide clear signals to other drivers on the road, indicating that they should stop to ensure the safety of the children.
Preventing Accidents: Failing to stop for a school bus can lead to accidents, which could have severe consequences, especially for vulnerable children. It's everyone's responsibility to prevent these accidents.
Respecting Traffic Rules: Adhering to the rules about school buses shows respect for the traffic laws and a commitment to the safety of all road users, especially the most vulnerable.

When normal microbiota become pathogenic and produce disease they are called opportunistic pathogens?
Opportunistic pathogens are normal microbiota that cause disease when a host's defenses are compromised. Risk groups include the very young, the elderly, and immunocompromised individuals. Examples include S. epidermidis causing infections in hospitals and E. coli causing urinary tract infections.
Explanation:When normal microbiota become pathogenic and produce disease, they are referred to as opportunistic pathogens. These are microorganisms that typically exist in concert with their host without causing disease, but can cause illness when the host's defenses are compromised. Conditions that can lead to such infections include weakened immune systems, breach in protective barriers, or an imbalance in the normal microbiota. High-risk groups for opportunistic infections are the very young, the elderly, pregnant women, individuals undergoing chemotherapy, people with immunodeficiencies like AIDS, post-surgical patients, and those with severe wounds.
An illustrative example is Staphylococcus epidermidis, which is a part of the normal skin microbiota and usually harmless, but can cause severe infections in a hospital setting, especially when introduced to the body through invasive medical devices. Another example is E. coli which is harmless in the large intestine but can lead to urinary tract infections if it manages to enter the bladder. These microbes become opportunistic pathogens because the normal defenses that would keep them in check are no longer functioning properly, thereby offering these microbes an "opportunity" to cause disease.

Why is urine more concentrated in the morning?
Final answer:
Urine is more concentrated in the morning due to dehydration during sleep and increased levels of Antidiuretic Hormone (ADH), which leads to greater water reabsorption and higher solute concentration in the urine.
Explanation:
The reason urine is more concentrated in the morning is due to a period of dehydration that occurs during sleep. During the night, your body continues to excrete metabolic waste and use water for various bodily functions, but you do not take in any fluids. Antidiuretic Hormone (ADH) plays a key role in this process. This hormone is released to regulate urine concentration and prevent diuresis – the excessive loss of water through urination.
While you sleep, ADH levels increase, causing the collecting ducts in the kidneys to become more permeable to water, resulting in the reabsorption of more water back into the bloodstream. This makes the urine that collects in your bladder overnight more concentrated, which explains the darker color and stronger odor in the morning. Additionally, the urine's concentration can be measured through the urine osmolality test, which clearly shows higher levels of solute concentration after a night of dehydration.
