5) Why is mimicry a helpful adaptation?
kompoz [17]
Ok so answer for 5 would be
5) a mimicry could be a great fully helpful adaption because as an example, the butterfly’s that blend in with trees, or the butterfly’s that look like birds, can either scare away predators or they can blend in.

6) as an example, a blue tongue skink has a blue tongue which is very common in venomous animals. Whenever said skink is threatened, it puffs up, opens its mouth, and hisses. When most predators see the tongue, they assume it’s venomous/poisonous because of the bright color. Another example would be milk snakes who look like coral snakes to scare away predators

Give the two ways nitrogen can be fixated so plants can use it to grow.
Maurinko [17]

\huge\mathfrak\red {Answer:}

<h2>Fixation</h2>

Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:

<h3>Biologically: </h3>

Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.

<h3>Through lightning: </h3>

Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.
