Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Answer:
D
Explanation:
<em>The correct option here would be</em><em> D</em><em>.</em>
The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.
For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.
Hence, the correct order of a typical endomembrane system function would be:
- <em>Ribosomes on the RER synthesize proteins.</em>
- <em>Proteins are packaged into transport vesicles.</em>
- <em>Golgi apparatus receives transport vesicles from the RER.</em>
- <em>Proteins are modified by the Golgi apparatus.</em>
- <em>Modified proteins may be secreted from the cell by exocytosis.</em>
The answer would be an Ecologist
