Answer:
The Rhizaria are supergroup species of mostly unicellular eukaryotes and classified as protista. Rhizaria include species like cercozoa, foraminifera and radiolaria.
<u>Some of the attributes of Rhizaria are:</u>
- non-photosynthethic in nature, but some have a symbiotic relationship with unicellular algae.
- express only rDNA sequences so they can vary in different forms.
- do not have clear morphological characters
- they mostly includes amoebas which functions for food engulfing and help to direct movement in rhizarian protista.
<u>Contribution of Rhizaria to the ecosystem:</u>
- There are known as abundant bacterial grazers, and play very important role in microbial food webs.
- They provide a wide diversity of marine organisms.
- important contributors to oceanic carbon pools .
Hence, Rhizaria are important part of ecosystem.
A compound is a combination of one or more elements that are bonded chemically. Examples are ozone (three oxygen atoms), water (two hydrogens and one oxygen), carbon dioxide (one carbon and two oxygens), and nitrogen gas (two nitrogen atoms)
<span>Be careful of some elements that combine with themselves in pairs to form compounds. Hydrogen, for example, is an element which you can see in compounds like water and methane, but when hydrogen atoms are floating around by themselves they pair up to make a diatomic molecule (H2). Hydrogen gas is made of pairs of hydrogen atoms (a compound), not individual free-floating atoms. Other elements behave like this too (helium, chlorine, oxygen, nitrogen, and iodine are examples).</span>
Answer:
<em>The correct option is C) H2SO4</em>
Explanation:
A molecule can be described as a substance which is made up of the same kind of atoms or element. For example, O₂, N₂ etc. Hence, option A is an example of an element.
A compound can be described as a substance which is made from different atoms or elements. For example, H2SO4 is made up of the elements hydrogen, oxygen, sulphur. Hence, option C represents an example of a compound.
Answer:
mitochondria
Explanation:
the mitochondria act as the powerhouse of the cell, creating energy for the cell to use.
