Answer:
If we're talking about human organism then
It is multicelular.
It has a backbone.
It contains cells without nuclei.
Explanation:
human as almost all animals in the world is multicellular meaning they have more than one cell (some bacterias has only one)
backbone or "vertebra" is the is the bone of our back who supports us making us stand up.
Yes our cells contain nuclei
, The nucleus contains nucleoplasm, a component where it is immersed in genetic material and as structures that are important for the performance of its functions
And finally our body don't have radial symmetry, radial symmetry is when you can "cut" the image in more than one piece keeping the symmetry in every side, some animals with radial symmetry are the starfish and the jellyfish.
a) A warm air mass rises above a cold air mass during a warm front, but two cold air masses surround a warm air mass during an occluded front.
Orientation behaviors usually determine the type of environment that an animal will prefer to live. Animal orientation behavior is a complex process which determine how an animal receives information from the external world and how it responds to it.
Answer:
Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail.

Answer:
The reason why the ecosystem has many different kinds of plants is because of the soil, or the environment around them. Also, some biotic factors like animals or humans could be the reason. The humans may have planted seeds there, and probably some abiotic things like soil could also be the reason why. The plants that grow there receive a lot of rain, or the limiting factor is the rain, and the type of plants that grow there don't need much water to survive.
