Answer:
Commensalism
Explanation:
Commensalism is when one organism benefits and the other doesn't benefit and is also not harmed. The tree is helping the orchid and the orchid isn't benefiting or harming the tree.
The correct answer to this is:
“Astrocytes”
Astrocytes also called star cells due to their shape are the
most abundant glial cells in the brain. Extensions from these cells encase
capillaries and offer extra control over which materials enter or leave the
intercellular fluid of the CNS thus acting like a permeability membrane.
<h2>Availability of Plankton</h2>
Explanation:
- The term plankton comes from the Greek derivative planktos, meaning wandering. Organisms in this group spend either part or all of their life in a drifting state, with no ability to swim against a current. Most have little or no ability to swim at all. Though some are larger, most planktonic creatures are microscopic and make up the bottom of the food chain in aquatic environments
- Plankton can be divided into two categories: phytoplankton are those organisms that are plant-like, and zooplankton are organisms that are animal-like. Interestingly enough, many planktonic species are neither plant nor animal but are creatures that belong to the kingdom Protista
- Zebra muscles are found in water bodies which attached to pipes and other surfaces of water supply to impliment the availability of plankton
Since it has 4 protons, it must have an atomic number of 4. (That makes it beryllium.)
Since it has a 4 protons and 5 neutrons, it has a mass number of 9.
I would go with false, because not only 100,000 genes, there are lots to those. and there are not even like 100,000 genes, that is not really possible!!
hope that this helps you! =)
