<span>Na is the chemical symbol for sodium. Na+ is formed when sodium loses an electron from its outer shell (the number of electrons and protons is now unbalanced, giving an overall positive charge) and becomes a sodium ion. Losing an electron happens when a metal reacts with a non metal.</span>
The first step would be to denture the starting solution that contains the DNA, enabling the DNA to separate into two strands.

Answer and Explanation:
Invasive species are not native to an ecosystem/environment to which they've been introduced, which can cause disastrous disruptions to various food chains/webs and other native species' populations.
In this case, your cousin is bringing in a plant from overseas, so it clearly will be an invasive plant. You can tell them the following:
- this plant may take over the feeding source of native plants, causing those populations to decrease drastically or possibly even be wiped out
- secondary consumers that had once relied on those native plants for food energy will now have limited resources, competition will increase, and these consumers may begin to die off
- tertiary consumers that consumed these secondary consumers will begin to die off, as well
- this chain reaction will ripple through the entire food chain and food web, and totally disrupt the existing ecosystem
Thus, your cousin shouldn't plant this organism in their backyard and should instead destroy it.
Answer:
D.
Both the femur and humerus bone have what's called 'spongy bone' inside them and hollow spaces full of yellow and red bone marrow. Additionally, both bones do not attach to the axial skeleton but rather attach to the pelvic or hip bones; while they are both strong bones, they are not made of only compact bone but are made of 'spongy bone' inside them. Lastly, they do not protect any organs but rather allow for movement. D, They both have hollow spaces filled with bone-generating cells, is the best answer in this case
