Answer:
d) Stratified layering
Explanation:
The wall of the ducts is formed by a lining epithelium that forms a small tube with a central lumen. The epithelium that forms the duct is initially of the simple cubic type. If the gland is small and the duct is short, it maintains this structure throughout its course, subjected to a high degree of pressure.
These ducts have from more complex glands the duct epithelium ends up becoming simple prismatic and may even become stratified. In this case, the tissues have stratified layering
Normal polarity
Explanation:
Earth's magnetic field used to be twice as strong 1.5 billion years ago as it is today and Earth's temperature other than what the geologists see from the 'normal' pattern. It has been noticed that some volcanic rocks were magnetized in opposite direction to the direction of the local Earth's field. It is clear that the Earth has experienced the normal polarity 1.5 years ago but at that time, the Earth's polarity was poorly understood.
Answer:
A. outside plasma membrane:
1. cell wall 6. flagella
B. outside of the cell
4. fimbriae 5. pilus
C. in cytoplasm
2. nucleoid 3. ribosome
Explanation:
Bacteria is one of the three domains of cellular organisms. Bacteria are prokaryotes, cells that lack a true nucleus and membrane-bound organelle.
The plasma membrane is the outer membrane that enclosed the cytoplasm and cytoplasmic substance. The cell wall is covering the present out of the cell membrane or plasma membrane. Flagella are attached to the plasma membrane but it is present outside of the plasma membrane.
Fimbriae and pilus are the structure present outside of the cell wall and help to attach it to other cells or any surface. Nucleoid and ribosomes are present in the cytoplasm of the bacterial cell.
The answer is c. Adaptation
Adaptation is a physical characteristic that helps an organism survive in an environment. This help them survive in a natural selections.
The examples are :
- cactus that evolved to change its body structure to retain as much water as possible
- Bat that have adapted their hearing to hunt at night
I think all of them are correct
