Answer:
An index fossil is also known as guide fossils or indicator fossil. They are fossils used to determine and identify geologic periods.
The main characteristics of an index fossil include :
1.It must be distinctive.
2.It must be widespread.
3. It must be abundant
4. It must be limited in geologic time.
Due to trends and studies of most fossil-bearing rocks being formed in the ocean, the major index fossils are mostly marine animal or plant organisms.
Answer:
Hotspots from under the ground
Explanation:
There are three different situations where an volcano can form. A divergent boundary, where two tectonic plates move away from each other, subduction boundary, where one of the tectonic plates moves under the other, and a hotspot. Scientists are not completely sure how hotspots form.
<span>The correct answer is B. Hepatitis B. That is because the other things mentioned here are bacteria which is why they're treated with antibiotics or even more serious things in case like tetanus so as to prevent blood poisoning and sepsis and infections and similar things. Tubercolosis can especially be dangerous if not treated.</span><span />
Energy is transfered from a molecule of sugar to atp by cellular respiration
Answer:
The correct order is - 3. ribosomes 5. the endoplasmic reticulum 1. the Golgi apparatus. 4. transport vesicles. 2. the plasma membrane.
Explanation:
The protein needs to be transported from the cytoplasm to out of the cells for their target site, for example, insulin and enzymes. The protein synthesizes at the ribosome by the process of translation. It transported to the endoplasmic reticulum and move to the Golgi apparatus where it packaged and modified in the transport vesicles so it can move to, and pass through the plasma membrane.
Thus, the correct order is - 3. ribosomes 5. the endoplasmic reticulum 1. the Golgi apparatus. 4. transport vesicles. 2. the plasma membrane.
