Serika is nervous because she noticed that as her daughter is sleeping, her hands and feet start twitching. What causes this? What is it called? What is happening in the brain? What other physiological signs should Serika notice related to this sleep stage?
These twitches are most likely "sleep starts,'. They are are brief movements of the arms and legs that occur as Serika's kid falls asleep. Sleep starts affect up to 70% of children and adults. The technical name for "sleep starts" is hypnagogic or hypnic jer.ks.
What causes sleep starts?Tiredness, stress, or a lack of sleep may aggravate them, so it's worth reviewing the child's sleeping patterns.
What is happening in the brain?Hypnic jer.ks and other forms of myoclonus originate in the same area of the brain that regulates your startle reflex.
Researchers believe that as you fall asleep, a misfire between nerves in the reticular brainstem occurs, causing a reflex that results in a hypnic je.rk.
What other physiological signs should Serika notice related to this sleep stage?Hypnagogic je.rks most frequently occur at random, generally in the sweet zone between being awake and falling asleep.
They may move your entire body or just a portion of it. A especially severe hypnic jolt might cause you to feel as if you're falling and prevent you from falling asleep.

(30 POINTS) how do plants maintain homeostasis? (free write)
Answer: Hello: )✨ how do plants maintain homeostasis? is easy so as we should know that As water leaves the plant tissues into the atmosphere, it takes energy with it in the form of heat. Much like when we sweat, this allows the plant to cool and maintain homeostasis. we should also know that most Plants take in carbon dioxide and release oxygen. Did you know they also regulate how much they take in and let out? Leaves have stomata, holes on the underside, that expand and contract to get just the right combination. That's homeostasis.
Explanation: Environmental factors may affect the plants. However, they maintain the internal conditions by self-regulation, known as homeostasis, to adjust to the changing environment. This includes maintenance of the plant's internal temperature and fluid.
Hope this helps <3
Answer:
Transpiration provides evaporative cooling. As water leaves the plant tissues into the atmosphere, it takes energy with it in the form of heat. Much like when we sweat, this allows the plant to cool and maintain homeostasis.

Which of the following influences the amount of ozone pollution near Earth's surface?
O An area's weather patterns
O Nearby water resources
O Volcanic eruptions
O Plants undergoing photosynthesis
All the four options can lead to ozone pollution near the earth's surface.
Ozone Pollution- Increased wheezing, coughing, and chest tightness are brought on by ozone pollution, which results from hydrocarbon and nitrogen oxide emissions from cars and other sources mixed with sunshine.
Plants undergoing photosynthesis- Significant producer of VOCs (Volatile Organic Compounds) is woody vegetation. Before they react to generate ozone in the atmosphere, where it can linger for several weeks, NOx and VOCs can be transported over great distances by local weather patterns.Volcanic eruptions- Volcanoes probably generate enough bromine to deplete the ozone layer locally and alter the chemistry of the stratosphere. According to estimates, 1 to 5 percent of ozone damage is thought to be caused by volcanoes, 15 to 20 percent by other natural sources, and a staggering 75 to 85 percent by human activity.Water resources- From farms, factories, and towns, streams and rivers transport pollutants like chemicals, fertilizers, and heavy metals into our bays and estuaries, where they are then transported out to sea. The wind also brings in marine waste, particularly plastic, as does water from storm drains and sewage systems.Weather Patterns- As a result of global warming, there will be an increase in more extreme weather, including heat waves, extreme rainfall events, and other phenomena. Because the chemical reactions that produce ozone in the atmosphere take place more often in hot temperatures, heat waves increase the amount of ground-level ozone pollution.To learn more about ozone pollution- https://brainly.com/question/14154063

what are the 3 constant variables?
Constant variables are all the variables whose values or states remain the same in an experiment to avoid their influence on results. Constant variables that could apply to the experiment: City, Schedule, Ticket Cost.
What is a constant variable?
Several variables are involved in an experiment. Among them are the ones in which the researcher is interested and the ones that are not of interest.
Constant variables are the ones in which the researcher is NOT interested. But since these variables might influence the results, the researcher needs to keep them constant to avoid affecting the dependent variable response.
So, constant variables are all the variables whose values or states remain the same in an experiment.
In the exposed example we need to identify three POTENTIAL constant variables. So first, we will identify the question, the independent and dependent variables, and then we will propose the three constant variables.
