Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.

In a polar covalent bond, the bonding pair of electrons in the bond are attracted more strongly to one molecule than the other. This means the electrons are pulled closer to one atom than the other.
In the example of water, the electrons, in the hydrogen-oxygen bond, are more attracted to oxygen and therefore the electrons are drawn closer to the oxygen. This leads to a slightly negative charge on the oxygen and a slightly positive charge on the hydrogen.
The codons each code for something but all together they are the instructions for life. If the codons were the words in the manual, they would make up sentences which are the instructions for how the organism should work and be built. Let me know if you need more information.
I believe this problem has the following choices:
> Denaturants may affect the tertiary structure of
prions
> Prions are smaller than viruses, which are affected
by radiation
> Prions are proteins
> Prions do not contain genetic information, which is
affected by ionizing radiation
The correct answer is:
* Prions do not contain genetic information, which is
affected by ionizing radiation
