Answer:in the third stage

Explanation: Aerobic respiration requires oxygen to breath in the third stage. In the third stage glucose molecule is the source of energy. Aerobic respiration occurs were cell use oxygen to convert glucose into energy. When you breath in,you breath in oxygen,when you breath out,you breath out carbon dioxide.

During cellular respiration,our body needs the oxygen we breath in,to get energy from the food we eat. cell uses oxygen to break down sugar.

Answer:

  • The cellular respiration occurs in two main forms or mechanisms, the first one is the aerobic respiration which obviously takes place in the presence of the oxygen,O₂ molecule. While, the second takes place in the absence of the oxygen,O₂ molecules.
  • For, the aerobic form of cellular respiration the oxygen is required to be present during the  process of  releasing the optimum amount of energy or executing of the whole process in a more proper way.
  • <u>As, the aerobic respiration is executed in the following three steps:</u>
  1. Glycolysis.
  2. The Kreb's cycle.
  3. And the electron transport chain, to which the oxygen is mandatory or required.

Answer:

It goes to the plants or the predators that ate the organisms

Explanation:

Decomposers will break down carcasses into nutrients and provide nutrients for plants in the form of dirt

The image shows rock strata from three different regions on Earth. Identify all the layers that contain an index fossil
FrozenT [24]

The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.

The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.

By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.

which part of the brain plays a key role in forming and storing the implicit memories created by classical conditioning?
inysia [295]

The part of the brain which plays a key role in forming and storing the implicit memories created by classical conditioning is the Cerebellum.

As well known, the central nervous system (CNS) is made up of the brain and spinal cord. The peripheral nervous system (PNS) on the other hand is composed of spinal nerves that branch from the spinal cord.

The brain is subdivided into 3 parts:

  • The Cerebrum which is the largest part of the brain and is composed of right and left hemispheres and is responsible for performing higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

  • The Cerebellum which is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance. An additional function of the cerebellum is the formation and storage of memories created by classical conditioning.

  • The Brainstem which acts as a relay means connecting the cerebrum and cerebellum to the spinal cord. It is responsible for many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

Ultimately, The part of the brain which plays a key role in forming and storing the implicit memories created by classical conditioning is the Cerebellum.
