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.

Describe the process of oxidation in terms of electrons AND energy.
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. Together, they are called oxidation-reduction or redox reaction.Learn more about oxidation at: https://brainly.com/question/3867774?referrer=searchResults

Answer:
Hello that's the answer and thank you
Explanation:
make me brainliest pls
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.

Renewable energy sources account for the majority of energy production. Please select the best answer from the choices provided T F.
Renewable source of the energy is defined as the energy collected from renewable sources like wind, water, and light, which can be replenished on the Earth over time.
The given statement is False.
Renewable energy accounts for 20% of the total utility scale. The majority of the energy is derived from non-renewable sources. The non-renewable source of energy cannot be replenished over time and can be exhausted after certain years.
Renewable resources like, wind and waves are used to obtain energy by applying scientific equipment and technologies. The output of renewable sources of energy is lesser as compared to non-renewable sources of energy.

2. A 2 kg bowling ball rolls at a speed of 5 m/s on the roof of the building that is 40 m tall.
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

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.

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.

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.
