B. Heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. Lactate is being transported to her liver. This is a result of aerobic respiration.
C.Strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
The correct answer is option D. Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
During exercise, the muscles use the oxygen present there and become deprived of oxygen. Due to less oxygen, the anaerobic respiration occur in the muscles, to overcome this, the heavy breathing takes place. heavy breathing brings the oxygen to the muscles.
During anaerobic respiration, the glucose is broken down into the lactate and the lactate is transferred to the liver for the gluconeogenesis and to maintain the constant supply of the glucose to the muscles.
A simple diagram of Cori cycle (lactic acid cycle) is given below:
The four types of stem cells are as follows:
Stem cells may be defined as a type of cell that can significantly divide and in doing so produce a replica of itself as well as a daughter cell that can undergo further development and differentiation.
Therefore, the four types of stem cells along with examples are differentiation are well described above.

Answer:
The correct answer would be the virus envelope.
Viral envelope is a protective covering present around the capsid proteins in some viruses.
It is usually derived from the cell membrane of the host and thus it is composed of lipid and viral proteins.
It provides stability to the viral particle, helps in protecting the viral genome, and aids in the fusion of the virus with the membrane of the host.
Examples of viruses in which envelope is present: herpesviruses, poxviruses, flavivirus, hepatitis D et cetera.
Examples of viruses in which envelope is absent: adenoviridae , papillomaviridae , picornaviridae , caliciviridae et cetera.
Answer:
The one cell of a unicellular organism must be able to perform all the functions necessary for life. These functions include metabolism, homeostasis and reproduction. Specifically, these single cells must transport materials, obtain and use energy, dispose of wastes, and continuously respond to their environment.
