3. How would you date a sample of rock that you suspect as being one of the earliest on Earth? (1 point)
Kay [80]
<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>

The following are the steps for B-cell activation. The steps are in an incorrect order.
Nataly_w [17]

Answer:

4. B cells become activated by interacting with helper T cells.  

1. B cells display antigens in MHC class II receptors on the cell surface.  

2. Antibodies released by plasma cells bind to the antigen so they will be destroyed by other cells of the immune system.

3.B cells rearrange their DNA to create a unique B-cell receptor.  

5. B cells undergo clonal expansion.

6. B cells digest antigens that bind to the antibodies on their surface.

Explanation:

B-cells get activated by interacting with helper T cells when they bind to the antigen to receptors i.e (MHC class II receptors on the cell surface) on the surface of the cell. Series of activities such as release by plasma cells which cause rearrangement of B cells causes the cell to divide and proliferate. The process through which daughter cells arise from a parent cell called clonal expansion.

These species grow uncontrollably and can take over and destroy an ecosystem:
Shalnov [3]
<span>invasive

Invasive species can threaten an ecosystem and the biodiversity of the organism that exist in the present environment when the invasive species increase rapidly in number. 
</span><span>Exotic species are a threat to biodiversity because they alter the ecosystem of that area. They share food and habitat resulting in unbalanced ecosystem. Also, habitat destruction destroys the habitat of all the life forms in that area. </span>
