A cousin who has been traveling overseas sneaks a plant through customs (who help along with the USDA, help to prevent invasive
Reil [10]

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.

It has polar head and a nonpolar tail. Proteins embedded within the phospholipid bilayer have the same function of the plasma membrane that includes selective transport. The phospholipid bilayer consists mainly of the lipid molecules.

Answer:

hope this helps

Explanation:

The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.
