What information can a scientist learn directly from a single fossil? O A. What the organism looked like B. How the organism is related to organisms on Earth today C. How many offspring the organism produced D. How long the organism lived
Answer:
A. What the organism looked like.
Explanation:
From a single fossil you can see what the organism looked like, but you need more than one fossil to know how long it lived. You can't determine how many offspring an organism produced from any fossil. And how the organism is related to organisms on earth today can be learned indirectly from fossils, using other information and technology.

1) Nitrogen fixation
2) Nitrification
3)Assimilation
4)Ammonification
5)Denitrification
Answer:
hope this helps!
Explanation:
In general, the nitrogen cycle has five steps:
- Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
- Nitrification (NH3 to NO3-)
- Assimilation (Incorporation of NH3 and NO3- into biological tissues)
- Ammonification (organic nitrogen compounds to NH3)
- Denitrification (NO3- to N2)

how do red blood cell,muscle cells and nerve cells differ from a typical animal cell
Answer:Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.

Which of the types of cells in T. adhaerens contain cilia? (Choose all that apply)
gland cells
cylinder cells
fiber cells
cover cells
Answer:
Its Gland cells, Cylinder cells, and Cover cells
Explanation:
Cells like Gland cells, Cylinder cells, and Cover cells contains cilia in T. adhaerens.
What is T.adhaerens?Trichoplax adhaerens is one of the three named species in the phylum Placozoa. They have two cellular layers: the top epitheloid layer is made of ciliated (cover cells) flattened toward the outside of the organism, and the bottom layer is made up of cylinder cells that possess cilia used in locomotion, and gland cells that lack cilia.
Moreover, trichoplax generally has a thinly flattened, plate-like body in cross-section around half a millimetre, occasionally up to two or three millimetres. The body is usually only about 25 µm thick.
Therefore, these colorlessly gray organisms are so thin they are transparent when illuminated from behind, and in most cases are barely visible to the eye.
