Why are some people left handed and some right handed

1 answer:

4 0

Arm and hand movements start in the brain, in an area called the motor cortex, which sends a signal to the spinal cord that's translated into a motion. The researchers found that while the fetus is growing in the womb, up until about 15 weeks, the motor cortex and the spinal cord are not yet connected, but right- or left-handedness has already been determined.

Homeostasis keeps the organism in a dynamic equilibrium within the homeostatic range. A disruption in dynamic equilibrium is indicated by the temperature change between point C and D. Option C is correct.

<h3>What is homeostasis?</h3>

Homeostasis is the organism's capacity to keep the body in constant internal equilibrium, even when the external environment is oscillating.

Homeostasis is critical to keep the correct internal functioning of the body.

Different functions -blood pressure, body temperature, respiratory rate, and blood glucose levels, among others- are kept in a restricted range around a reference point, even though external conditions may be changing.

When a sudden change occurs in the internal functioning that disturbs this equilibrium, the organism counters it back by negative or positive feedback.

<h3>Graph interpretation</h3>

In the exposed graph we can see,

The restricted range of homeostasis at a constant temperature around 37ºC.

Six reference points (A-F) withing 12 hours.

Dynamic equilibrium is kept in the range of homeostasis around 37ºC, excepting for point D that reaches 38ºC.

The references point A, B, and C suggest that during the first 10 hours, approximately, the body was in equilibrium.

A change in the internal functioning broke the equilibrium, rising temperature to 38ºC, out of the homeostatic range.

The organism took the internal values to their original state, and at points E and F, the organism was in equilibrium again.

A disruption in dynamic equilibrium is indicated by the temperature change between point C and D.

I just need 1 example I'll make you brainliest! How do cells form?

tatyana61 [14]

Cells that do a similar activity join together to shape body tissue, for example, muscle, skin, or bone tissue. Gatherings of various kinds of cells make up the organs in your body, for example, your heart, liver, or lungs. Every organ has own must do, however all organs cooperate to keep up your body.

What are some Major Characteristics Temperate Deciduous Forest

kramer

Answer:

The Temperate Deciduous Forest is a biome that is always changing. It has four seasons: winter, spring, summer, and fall. Constant rainfall and daylight saving hours also contribute.

Explanation:

Temperate deciduous forests get between 30 and 60 inches of precipitation a year, this helps keep the forest lush and green. When it comes to daylight savings in the fall, lack of sunlight can affect photosynthesis and the amount of sun the plant gets. Unlike the amazon forest, the temperate biome goes through all 4 seasons and has plant regeneration in the spring instead of constant vegitation.

Hope this helps :)
