Multicellular organisms are organized into various levels, including cells, tissues, organs, organ systems, and organisms. Each level has a unique role and is often comprised of lower levels, such as organs being made up of tissues, which are made up of cells.
Yes, indeed, multicellular organisms can be further organized into other levels. These include the cellular, tissue, organ, organ system, and the organism level. Higher levels of organization are built from lower levels. For instance, molecules combine to form cells, cells combine to make tissues, tissues form organs, organs come together to form organ systems, and organ systems combine to form organisms. Organisms are individual living entities. For instance, every single tree in a forest is an organism. Single-celled prokaryotes and single-celled eukaryotes are also considered organisms and are typically referred to as microorganisms.

An invasive species is defined as the organism that is not indigenous, or native, to a particular area. Invasive species can give rise to great economic and environmental harm to the new area.
Native species is defined as species which originated and developed in its surrounding habitat and has adapted to living in that particular environment.
Examples of invasive plant species are kudzu vine, English ivy, Japanese knotweed, etc. Animal examples are New Zealand mud snail, European rabbit, grey squirrel, carp, etc.

Answer:invasive
Explanation:
b. Scientists use relative dating to determine the absolute age of a new fossil.
c. Scientists use radioactive isotopes to determine the absolute age of a new fossil.
d. Scientists use index fossils to determine the specific years of age of a new fossil.
Answer:
Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.
(1) contraction of muscle tissue
(2) protein synthesis in a cell
(3) active transport of minerals
(4) movement of water across a membrane
Answer;
-Movement of water across a membrane
Explanation;
-Movement of water molecules across a membrane is an example of passive transport . Passive transport involves movement of ions and other atomic or molecular substances across cell membranes without need of energy input.
-Unlike active transport, passive transport does not require an input of cellular energy (ATP). Examples of types of passive transport are osmosis and diffusion.
The right answer is Change in color, production of gas, formation of precipitate.
Chemical changes alter the nature and characteristic properties of matter. New substances are formed as a result of the reaction.
It is said that a pure substance has undergone a chemical change if it has been transformed into one or more new pure substances which do not have the same properties as the starting substance.
The characteristic properties of the substances disappear and the products formed have new properties.
There are several (even more than three) that can recognize the presence of a chemical change.
* The formation of a gas (effervescence)
* Production or absorption of heat
* The production of bright light
* A significant color change
* A change of smell
* The formation of a precipitate
