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.

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.

The correct medical term for deficient activity of the adrenal glands is:
The correct medical term for deficient activity of the adrenal glands is "adrenal insufficiency," which encompasses various conditions related to inadequate adrenal function.
Primary Adrenal Insufficiency (Addison's Disease): This condition occurs when the adrenal glands themselves are damaged and cannot produce an adequate amount of essential hormones, particularly cortisol and aldosterone.
The most common cause of primary adrenal insufficiency is autoimmune destruction of the adrenal cortex. Symptoms may include fatigue, weakness, weight loss, and darkening of the skin.
Secondary Adrenal Insufficiency: Secondary adrenal insufficiency arises when the pituitary gland or hypothalamus in the brain does not release adequate amounts of adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce cortisol.
It can result from various factors, such as tumors, pituitary disorders, or abrupt withdrawal from long-term corticosteroid therapy. Symptoms are similar to primary adrenal insufficiency.
Adrenal insufficiency can lead to a range of symptoms, including fatigue, weakness, weight loss, low blood pressure, and electrolyte imbalances.
It can be life-threatening if left untreated. Diagnosis often involves blood tests to measure hormone levels, including cortisol and ACTH, as well as imaging studies to identify any underlying causes.

Vitamin d regulates the absorption of ______ from the small intestine. calcium and fluoride phosphorus and magnesium calcium and magnesium calcium and phosphorus
Vitamin D is crucial for the absorption of calcium and phosphorus from the small intestine. It facilitates the intake of these minerals, which are key to bone health and the prevention of skeletal diseases like rickets and osteomalacia.
Explanation:Vitamin D regulates the absorption of calcium and phosphorus from the small intestine. It is essential for bone health because it promotes the synthesis of a specific calcium-binding protein, which is involved in the active transport of calcium across the small intestinal mucosa. Moreover, vitamin D facilitates the intestinal absorption of calcium and phosphorus, which are vital components of bone in the form of calcium phosphate and calcium carbonate.
Without adequate vitamin D, the body cannot effectively absorb calcium from the diet, leading to potential skeletal problems such as rickets in children and osteomalacia in adults, which may contribute to osteoporosis.
Thus, sufficient intake of vitamin D is critical not only for the absorption of calcium but also for maintaining normal calcium concentration in the blood and for the process of bone remodeling.
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).

The client with o+ blood is in need of an emergency transfusion but the lab does not have any o+ blood available. which unit of blood can be potentially given to the client?
In an emergency, a client with O+ blood can receive O- blood due to its universal donor status. If O- is unavailable, blood types with the same Rh factor, such as A+ or B+, might be used cautiously, considering the risk of immune reactions. Research into artificial blood substitutes aims to eliminate the incompatibility risk in transfusions.
If a client with O+ blood requires an emergency transfusion and O+ blood is not available, the following blood type can be given:
The first alternative would be O- blood, as it lacks the A, B, and Rh antigens, making it a universal donor blood type that is compatible with all other ABO and Rh blood groups.If O- blood is also not available, then in an emergency, the next safest alternative would be a blood type with the same Rh factor, such as A+ or B+, to avoid Rh incompatibility reactions. However, this introduces a risk for an immune reaction due to the A or B antigens present in donor blood.The critical principle to be followed is that transfused blood must not contain antigens that the recipient's antibodies can attack. In an emergency where universal donor blood is not available, and the patient's life is threatened by acute hemorrhage, medics can use saline solutions to replace some lost blood volume or potentially transfuse compatible blood types if cross-matching is not feasible.
Research is ongoing to develop artificial blood substitutes, with oxygen carriers like hemoglobin and perfluorocarbons, which would allow for transfusions without the risk of incompatibility.
