Difference between native, nonnative, invasive,and exotic species?​

Biology

Strike441 [17]3 years ago

Answer: Native species can be the hardest to explain.  Simply put, natives are species that are from a particular place without human intervention–humans didn’t put them there directly or indirectly.  Digging into that a bit means that “native” can vary a lot based on what scale one is considering, and whether or not there are records of pre-settlement organisms (think fossils). As with anything, there are lots of other names for native, like “indigenous.” Non-native species spread by natural process or human activities. ... When an exotic species becomes harmful to the ecosystem, it is called an invasive species. The main difference between exotic and invasive species is that exotic species is harmless to the ecosystem whereas invasive species is harmful to the ecosystem.

"if a bacterium cannot use citrate, what result will occur in citrate agar?"
Annette [7]

If a bacterium cannot use citrate agar will not change its color (stays green). On the other hand, if bacteria have the ability to use citrate, the medium will change its color from green to blue.

This happens because citrate agar contains pH indicator such as bromothymol blue which transforms from green to blue in alkaline conditions.

Evaluate the following statement: Volcanoes are only found along coastlines.<br><br>Please help​
d1i1m1o1n [39]

Hey :) hope your day is going well. :P I listed some information below, that may or may not help!

<em>"Evaluate the following statements. volcanoes are only found along coastlines."</em>

<u><em>False!</em></u>

<em><u>Most are found along plate boundaries and hot-spots. :) </u></em>

They are found along plate boundaries because when the plate's collide together, <u>they may leave cracks</u> behind and may turn later into small hills and eventually grow even larger as time goes, and <u>produce magma from under the earth's layers</u>.

Hope this helped you, and as always remember if you need any more help, mssg me and i'll answer any questions you may have. <u>Have a great day.  :)</u>

What element is necessary for the production of thyroid hormone?
liubo4ka [24]

Answer:

Iodine

Explanation:

This is a trace element needed for the  synthesis of the two thyroid hormone ; T4- thyroxine and T3-triiodothyronine. Four iodine molecules are added in T4 synthesis, and  three for T3 synthesis. Generally T4 is the major hormone produced, but  biologically transformed into active form T3.

Iodine majorly and selenium are the two trace elements needed for thyroid hormones synthesis. Therefore required amount of iodine is important in daily diet. iIn adequate supply of this leads to under production of iodine called hypothyroidism. poor brain development ( especially in kids),and goiter.

Sea foods . eggs, poultry seaweeds are rich sources of iodine.

Conversely, when  excessive amount is present in the blood, autoimmune thyroid diseases can occur,including cancer developments in the thyroid gland due to hyper cell activities.
