The hypodermis (subcutaneous tissue) is the innermost layer of skin in your body. The dermis is the middle layer. The epidermis is the outermost layer.
<h3>What does the subcutaneous layer consist of?</h3>
Subcutaneous tissue is the deepest layer of your skin. It's made up mostly of fat cells and connective tissue. The majority of your body fat is stored here. The subcutaneous layer acts as a layer of insulation to protect your internal organs and muscles from shock and changes in temperature.
<h3>What is not found in dermis?</h3>
The answer is C fat cells. So the dermis is between the epidermis and the subcutaneous tissues.

Answer:
Neurons have stable, relatively unchanging internal environments.
Explanation:
Neurons or nerve cells is the structural and functional unit of the nervous system. Neurons consists of the dendrites, axon, cell body and different cell organelles.
The neurons have mitochondria that meets the high ATP requirement and and consume more oxygen. The network of rough endoplasmic reticulum and ribosomes produce large number of proteins in neuron. The internal environment is never stable and gets changed as the nerve impulse transmission occur through the neuron. The membrane potential of the neuron gets changed and changes its internal environment.
Thus, the correct answer is option (B).
Answer:
The rate of photosynthesis was more than the rate of respiration
Explanation:
Photosynthesis has to do with the synthesis of sugar molecules from inorganic products such as water and carbon dioxide. Respiration on the other hand has to do with breaking down of the sugar molecule from photosynthesis to release the energy locked up in the sugar for various metabolic processes in the plant's body.
<em>If both processes are balanced, there will be no net sugar production. Hence, if an excess of sugar produced fossil fuels, it thus means that there was net production of sugar in the past. The rate of photosynthesis was more than the rate of respiration in the past.</em>
