I think the answer is B, because only plant cells contain a cell wall, while the other answers contain an organelle that can be found in multiple cell types.
Answer:
Both conditions are caused by an inability of the body to produce adequate acetylcholine.
Explanation:
Botulism is a potentially fatal condition caused by the toxin of bacteria <em>Clostridium botulinum</em>. Early symptoms are weakness, slurred speech, blurred vision etc. It may lead to vomiting, abdominal swelling and respiratory failure if not treated. The toxin hinders the release of neurotransmitter acetylcholine due to which motor neurons are not able to send signals to muscle cells. Muscles are not able to function properly due to which paralysis occurs.
Myasthenia gravis is also a neuromuscular condition like botulism. But unlike botulism release of acetylcholine is not hindered here. The receptors for acetylcholine are destroyed or altered by body's own immune system. Acetylcholine despite being present is not able to relay the signal which leads to muscle weakness. Symptoms are almost similar to those of botulism.
Hunting is regulated because plants still need to be eaten by the deer. if they arent, a plant species grows uncontrollably and kills off other plants.
People with two copies of the sickle cell gene have the disease. People who carry only one copy of the sickle cell gene do not have the disease, but may pass the gene on to their children. Abnormal hemoglobin, called hemoglobin S, causes sickle cell disease (SCD). The problem in hemoglobin S is caused by a small defect in the gene that directs the production of the beta globin part of hemoglobin. This small defect in the beta globin gene causes a problem in the beta globin part of hemoglobin, changing the way that hemoglobin works.
Answer:
algae are autotrophs, and fungi are heterotrophs. algae contain photosynthetic pigments. fungi are capable of digesting non-living, organic material, and also absorbs simple nutrients by the fungal hyphae
