Outline what has to occur in the body for a reflex and a voluntary action to occur.
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.

Complete this sentence. Excess ____________ from human activities can cause harmful algal blooms (HABs), such as red tide, that produce toxic effects on aquatic species, marine mammals, and birds, as well as on the humans who eat them.
Nitrogen
Carbon
Salt
Heat
Answer: Nitrogen
Explanation:
Harmful algal blooms can occur in lakes, reservoirs, rivers, ponds, bays and coastal waters, and the toxins they produce can be harmful to human health and aquatic life. Harmful algal blooms are mainly the result of a type of algae called cyanobacteria, also known as blue-green algae.
The answer is nitrogen, nitrogen helps algae grow and when it grows in excess it takes away the dissolved oxygen from the water which kills off fish, which puts more nitrogen in the water making algae grow even more until it snowballs and destroys the aforementioned ecosystem.

Phenomenon: Miss Westbrook visited family in Aspen last spring. Aspen is in Colorado and has an elevation of 8,000-9,000 feet. The Bay Area has an elevation of 0-100 feet. Miss Westbrook’s breathing and heart rate both sped up every time she went hiking or skiing in Aspen. Why do you think this happened?
Hint: Your brain regulates the rate and depth of your breathing to match the needs of your body for 02 intake and CO2 removal.
Breathing rate refers to the number of breaths per minute.
This happened due to the low air pressure in the highest areas of Colorado, which made hard the intake of air.
Air pressure is fewer as the elevation in an area increases. In other words, the air over us is less, so the pressure that it makes is lower.
Miss Westbrook's heart rate and breathing sped up due to the low air pressure that she experimented with when ascending or when skiing in Aspen, which is very elevated. As the pressure is lower, not much air can enter the lungs, so her brain increases the breath rate to obtain the same amount of oxygen that her body had when breathing normally on the Bay. As there is not enough oxygen in her body, the brain also increases the heart rate to match the rhythm of the breath and deliver the scarce oxygen to the different parts of the body.
In conclusion, the increase in the heart and breath rate happens due to the low air pressure in elevated areas that makes our body find ways to compensate for the decrease in the amount of oxygen that our body can take.

How does your body respond to an increase in the need for energy----why would you need more energy?
Answer:
Exercise can boost energy levels by raising energy-promoting neurotransmitters in the brain, such as dopamine, norepinephrine, and serotonin, which is why you feel so good after a workout. Exercise also makes muscles stronger and more efficient, so they need less energy, and therefore conserve ATP.

Explanation:

Xylem and phloem are the types of tissues found in the vascular bundle of plants.
What is the vascular bundle of plants?
In animals, the bloodstream is used to transport nutrients throughout the body. This function is carried delivered via the vascular system, a network of tissues and fibers in plants.
The xylem and the phloem are the two primary tissue types that make up the vascular system. Water and dissolved minerals are distributed upward through the plant through the xylem, first from roots to the leaves. Food is transported from the leaves to the roots through the phloem.
A mature woody stem or root's principal component is made up of xylem cells. They are arranged vertically in the heart of the plant, creating a column that transports water and minerals taken up by the roots up the stem and onto the leaves.
Transporting the food that the leaves have produced downward via the stem is a similar network of phloem cells that line the outside of the xylem.
Therefore, the xylem and phloem are present in the vascular system of plants.

In deserts there’s a strong environmental pressure to conserve water. How did cactuses evolve to meet this pressure?
Answer:
Cacti evolved in the way that they are able to hold watter within themselves and their cells.
Explanation:
Cactuses have evolved in such a way that their roots and leaves hold water as long as possible. This gives the capability of cacti to meet this environmental pressure in order to conserve water.
What are the special adaptations of the cactus?Under desert climates, cacti have various numerous unique adaptations in order to facilitate their survival in the same habitat. It includes its roots, leaves as well as stems that enable it to thrive in desert environments.
These adaptations include: Leaves are reduced to spines to reduce water loss through transpiration. Wide and deep roots absorb rainwater on the surface and reach the underground deep water.
Therefore, cactuses have evolved in such a way that their roots and leaves hold water as long as possible.

Circle one: KE / GPE / both
Show your work for finding the values of each type of energy the object has:
Answer: Both
Explanation:
KE can be solve using the formula:
ke = 0.5 mv^2
where m is the mass of the object
v is the velocity
ke = 0.5 ( 2 kg ) ( 5 m/s)^2
ke = 25 J
the GPE can be solved using the formula:
GPE = mgh
where m is the mass
g is the acceleration due to gravity ( 9.81 m/s^2)
h is the height
GPE = ( 4 kg)(9.81 m/s^2)( 40 m)
GPE = 392.4 J

Hope it helps
Explanation:
mark me brainliest and follow me for more answers
Glycolysis and the citric acid cycle both produce carbon dioxide, which is a crucial byproduct (Krebs cycle). This oxidized carbon is a metabolic waste product that must finally be eliminated through transit to the lungs and subsequent exhalation into the environment.
What is the purpose of Krebs cycle?
Pyruvate is converted into three different products by the Krebs cycle: carbon dioxide, a little quantity of ATP, and the reduced molecules NADH and FADH.
Each acetyl group adds two carbon atoms to the citric acid cycle. On each cycle turn, two carbon dioxide molecules are emitted.
However, these do not include the identical carbon atoms that the acetyl group contributed on that turn of the circuit.
Therefore, carbon dioxide is constantly given off during the Krebs cycle.

Oxidation is described as the loss of electrons and energy by a molecule.
OXIDATION:Oxidation is a process whereby a molecule loses electrons (e-) or energy to become positively charged. Oxidation changes the oxidation number of the molecule involved depending on the number of electrons lost. Reduction is the opposite of oxidation, and it entails gain of electrons and energy by a molecule.
