Answer:

Fine grained

Explanation:

Fine grained is an igneous rock that is formed from quickly cooling lava, it is a kind of rock that has little grains that are less than 2 mm long, for this the grain is not visible to the naked eye, the grain on the igneous rock are dependant on the speed on which the lava is cooled, slow cooling allows for larger crystals and grains, while faster cooling creates smaller crystals and grains.

These are the answers to the following questions:

1. In what type of rocks would geologists most likely find evidence of past life forms?
-igneous rocks

2. The physical, chemical and biological laws that opeate today have also operated in geologic past. This statement relates to the principle of
-cross-cutting relationships

3. In general, the law of superstition states that in an underformed sequence of sedimentary rocks, each layer is
-older than the one below it

4. If a layers of sandstone is in contact with a mass of granite that contains small pieces of the sandstone, which rock is older?

what cellular mechanisms allow human body cells to maintain these concentrations ?

sweet [91]

Answer:

Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.

Use the numbers 1, 2, 3, 4, and 5 to place the protein creation steps below in the correct order. Ribosome attaches to the mRNA.

kirza4 [7]

Answer: The correct sequence for the protein creation is as follows-

1) Information is transcribed in DNA to mRNA.

2) mRNA leaves the nucleus.

3) Ribosome attaches to the mRNA.

4) tRNA anticodon carries an amino acid that compliments the mRNA codon.

5) The chain of amino acids forms a protein.

According to the Central Dogma, the genetic information is transferred from DNA to mRNA to Proteins.

The first step is transcription in which DNA is converted to mRNA with the help of enzyme RNA polymerase. In eukaryotic cells, this process occurs in the nucleus.

This is followed by translation, which takes place in the cytoplasm when mRNA leaves the nucleus.

Ribosomes are the specialized organelles, which act as the site for protein synthesis ( translation).

Ribosomes attach to the mRNA. tRNA brings amino acid, which has anticodon complementary to the codon present in the mRNA. A chain of amino acids is thus synthesized, which is called Protein.

A mite is a tiny organism that may "ride" on top of an insect such as a beetle in order to move quickly from place to place.

Whitepunk [10]

Answer: the beetle is neither harmed nor helped by the mite.

Explanation:In this case, the mite benefits because it gains transportation from the beetle. If the beetle is neither harmed nor helped by the mite, then the relationship between the mite and the beetle would be an example of commercialism.
