Answer:
as I know
Explanation:
<em>Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils. The “soft” tissues of an organism, such as skin, muscles, and internal organs are typically not preserved as fossils.</em>
Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.
Answer:
C. their gametes do not require water for fertilization to occur.
Explanation:
Seed bearing plants are plants that produce seeds. The gametes of seed-bearing plants do no depend on water for fertilization. Fertilization could occur through the transfer of pollen from the male gametophtye to the female gametophyte through animals or wind.
Unlike other plant types like the bryophytes, they rely on water for fertilization. They so have xylem and phloem as well as other plants. They also have stems,roots and leaves like other plants.
A citric acid cycle is less active when a cell has a high atp/adp ratio and high nadh/nad ratio.
<h3>What is cell and cell theory?</h3>
A cell is the structural and functional unit of life and it the the base of an living organism.
Cell theroy is a scientific theroy that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.Eukaroyatic cells have a nucleus enclosed within the nuclear membrane and form large and complex organism.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Therefore,a citric acid cycle is less active when a cell has a high atp/adp ratio and high nadh/nad ratio.

Phylogeny has to do with the history of the evolution of a species or a group, usually represented in the form of a phylogenetic tree. Since it studies evolution, it is only natural it could give us some kind of reliable information about the existence of life on Earth and how it all came to be.
