What is isotonic medium?A solution that has the same amount of salt as cells and blood. In hospitalized patients, isotonic solutions are routinely utilized as intravenous fluids. When a cell is immersed in an isotonic solution, there is no net movement of water into or out of the cell, and the volume of the cell remains constant. Isotonic solutions include 0.9% normal saline and lactated ringers. A hypertonic solution is one that has a greater solute concentration than the solution across the semi-permeable barrier.The isotonic solution allows the cells to move water and nutrients in and out of the cells. This is necessary for the blood cells to perform their function of supplying oxygen and other nutrients to other parts of the body.To learn more about isotonic solutions from the given link

What type of control exists in the somatic nervous system?
a. automatic
b. voluntary
c. reflexive
d. partial
e. involuntary
Voluntary control exists in the somatic nervous system.
The somatic nervous system (SNS), or voluntary nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles.
The somatic nervous system consists of sensory nerves carrying afferent nerve fibres, which relay sensation from the body to the central nervous system (CNS), and motor nerves carrying efferent nerve fibres, which relay motor commands from the CNS to stimulate muscle contraction.
The somatic nervous system consists of two parts:
Spinal nerves: They are mixed nerves that carry sensory information into and motor commands out of the spinal cord.Cranial nerves: They are the nerve fibres that carry information into and out of the brain stem. They include smell, vision, eye, eye muscles, mouth, taste, ear, neck, shoulders, and tongue.Function :
The somatic nervous system controls all voluntary muscular systems within the body, and the process of voluntary reflex arcs.
The basic route of nerve signals within the efferent somatic nervous system involves a sequence that begins in the upper cell bodies of motor neurons (upper motor neurons) within the precentral gyrus (which approximates the primary motor cortex). Stimuli from the precentral gyrus are transmitted from upper motor neurons, down the corticospinal tract, to lower motor neurons (alpha motor neurons) in the brainstem and ventral horn of the spinal cord: upper motor neurons release a neurotransmitter called glutamate from their axon terminal knobs, which is received by glutamate receptors on the lower motor neurons: from there, acetylcholine is released from the axon terminal knobs of alpha motor neurons and received by postsynaptic receptors (nicotinic acetylcholine receptors) of muscles, thereby relaying the stimulus to contract muscle fibres.

How does the greenhouse effect influence the climate on earth? choose the best possible answer.
The greenhouse effect influences climate by increasing the global temperature.
What is greenhouse effect?The greenhouse effects are effects due to the presence of greenhouse gases in the atmosphere.
The greenhouse gases form a layer of gas in the atmosphere and prevent reflected solar radiation from escaping back into space. They, therefore, warm up the atmosphere by increasing the thermal energy.
As the concentration of the greenhouse gases in the atmosphere increases, so also is the amount of reflected solar radiation that is trapped in the atmosphere.
Therefore, an increase in greenhouse gas concentration increases the global temperature. Temperature influences other climatic factors such as precipitation.
Thus, the greenhouse effects influence climate by causing a rise in global temperature.

The antifungals known as polyenes interact with ergosterol, a lipid unique to fungus membranes.
What is fungus membrane?The fungus's homeostatic regulation depends on the sterol-, sphingolipid-, and glycerophospholipid-rich fungal membrane. Azoles impair the normal stability of the fungal membrane by inhibiting the enzyme lanosterol-14-demethylase (Erg11 or CYP51), which converts lanosterol to ergosterol. Unfortunately, the widespread use of these drugs has resulted in the development of resistance mechanisms, including the activation of efflux pumps, the development of biofilms, and the overexpression or active site mutation of CYP51. The creation of novel inhibitors able to overcome the resistance was made possible by the crystal structures of mutant CYP51 enzymes from Saccharomyces cerevisiae and Candida albicans in association with azoles.

ocean system?
• A. Humans will have more available food.
• B. The atmosphere will have more oxygen.
• C. More shrimp will move into the area.
D. It will be more difficult for salmon to find food.
Answer:
D. It will be more difficult for salmon to find food.
Explanation:
Due to the plankton population decreasing, the shrimp would have less food. When the shrimp have less food to eat, their population would also decrease.
Since the shrimp population decreased, the salmon would have less shrimp to eat, making it more difficult for them to find food.
When one thing offsets the food chain, it begins to collapse. The smallest change could have a major consequence.

In nature, all organisms are subject to natural selection. some scientists have theorized that we have stopped evolving because we can control our environment and reduce selective pressures. do you agree or disagree that humans have stopped evolving? why?
No, humans haven't stopped evolving.
Why is it not possible to stop evolving?Extinction is the sole method that may effectively halt the evolution of any living being. Reducing and maintaining population size to a limited number of people can delay evolution. By reducing the introduction of new mutations into the population, this will reduce the amount of genetic variation that is lost through genetic drift. A population's capacity to evolve can be significantly reduced, but not entirely eliminated, by sustained limited population size because genetic variety is the foundation of all evolutionary change. But with humans, there is no doubt that this is not the case.
Since our population has been growing over the past 10,000 years, the contemporary human gene pool today holds a vast store of genetic diversity. Consequently, our capacity for evolution has never been greater. Indeed, instances of recent, positive selection created, not lessened by cultural change, have made use of this genetic variety. The distribution of genetic variation within and among local populations is fast changing, which is driving a significant evolutionary change in the human species. This transition is further fueled by a fundamental shift in the equilibrium between genetic drift and gene flow.
Even if our cultural innovations do decrease selection on a characteristic, that trait may nevertheless evolve in correlation with the evolution of another trait, frequently in a non-adaptive manner and occasionally in a moderately maladaptive manner. Humans will continue to evolve as long as there is a reproducing population.
