Answer:
a
Explanation:
you got to think single cell organisms were not abundant however the Co2 and salt compounds were as well as the oxygen needed to help evolve them which led the moncellular creatures to evolve into algae and fungi and then those 2 formed a symbiotic relationship to form lichen
Photosynthesis Is generally the opposite of cellular respiration. To drive the organisms metabolism photosynthesis has an exothermic reaction.
Answer:
hii there
how are you?
here's your answer
Explanation:
1 )
The five steps of the scientific method
Step 1: Ask a question or identify a problem. A scientist learns about the universe by observing
Step 2: Background research.
Step 3: Form a hypothesis.
Step 4: Experiment and observe.
Step 5: Draw a conclusion.
2 ) Matter is the stuff that makes up the universe everything that takes up space and has mass is matter. All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Both atoms and molecules are held together by a form of potential energy called chemical energy.
3 ) Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the state of matter. The three fundamental phases of matter are solid, liquid, and gas.
hope it helps you dear

The complete question is attached in the form of an image as it lacks an essential part of the question?
Answer:
Eukaryotic cell membranes:
phosphatidylserine - it is found in the inner leaflet of the membrane and plays role in the cell cycle signaling.
phosphatidylcholine - these are a major group of the membrane in eukaryotes.
phosphatidylinositol - it is also present in eukaryotic cells only in significant amounts
both bacterial and eukaryotic cell membrane:
phosphatidylglycerol - directly activates lipid-gated ion channels in both type of cell membrane
phosphatidylethanolamine - helps in assembling membrane proteins.
cardiolipin - it present in both eukaryotic and bacterial membrane however it makes 20% of the inner membrane of the mitochondrial membrane
Bacterial membrane:
No particular lipid
