What are his observations? We can’t answer this without knowing his observations if those are the conclusions. Please provide the rest of the information and I can answer.
Answer + Explanation :
Bacteria :
1) Approximately diameter is 1-5 micrometer
2) They are prokaryotic.
3) They have rigid cell wall containing peptidoglycan.
4) Replicate by binary fission
Fungi :
1) Approximately 3-10 micrometers in diameter.
2) They are eukaryotic.
3) Rigid cell wall containing chitin.
4) Replicate by budding or mitosis.
<u>Viruses :</u>
1) Approximately 0.02-0.2 in diameter.
2) They are eukaryotic.
3) They contain protien capsid and lipoprotien envelope.
4) Donot replicate by binary fission.
<u>Archae :</u>
1) Not typically associated with human disease.
2) Found in extreme environments.
3) Cell wall doesn't contain peptidoglycan.
Answer:
Mutation.
Explanation:
All adaptations begin as a genetic mutation because these adaptations passed from one generation to another generation through genes of that organisms. Organisms that are adapted to their environments and survive more better, it will produce more offspring in which that genetic characteristics are transmitted from the parents so we can say that genetic mutation is responsible for adaptations.
Answer:
Cell membranes are selectively permeable which means it allow certain molecules to move across it into and out of the cell. Cells need to be able to transport these substances to live and grow.
Transport of ions, water maintains the osmotic pressure of the cell. Transport of sugars like glucose is necessary to generate energy for the metabolic activities of the cell. Gases like CO2 are waste products of metabolic reaction which are removed by the cell through the cell membrane. Amino acids are required to make proteins.
Transport across cell can occur through active and passive transport and transport of these substance are necessary for a cell to live and function properly.
Once, a physician accept to treat a patient, their relationship will continue to exist until the patient no longer needs the physician, then the relationship will end naturally. But in a situation where the relationship has to come to an untimely end, the physician must avoid abandonment claim by giving sufficient notice of withdrawal to the patient, relatives or responsible friends and guardians of his patient in order to secure another physician.
