Answer: The two categories is porous evidence and nonporous evidence. Nonporous item of evidence is when you put the latent print on the surface and it just sits on the surface. Porous item of evidence is when you put the latent print on the surface and it absorbs the latent print deposit.
The graph below shows how the amount of carbon dioxide (CO2) in our atmosphere has changed since 1960. A graph that plots the amount of atmospheric carbon dioxide in the atmosphere from 1960 to approximately 2005. The x-axis shows the time in years. The y-axis shows the carbon dioxide concentration in parts per million. The concentration is increasing over time. Based on the information given in the graph, which of these phenomena has likely increased since 1960?

I need help in this problem for an assignment. Please
Answer:
1) increases
2)increases
3) Decreases
4) increases
5) increase
6) decreases
Explanation:
Let us remember that in a solid, the molecules of the substance are trapped in fixed positions hence the entropy of a solid is less than that of liquid as well as less than the entropy of a gas.
Reaction (1) and (2) deal with a change of state from solid to liquid or gas leading to increase in entropy.
In reaction (3) the aqueous reactants convert into a liquid product leading to a decreases in entropy.
Reaction (4) and (5) has to do with change of a solid to a gas as well as an increase in volume leading to an increase in temperature.
For reaction(6), a solid is formed so entropy decreases
What term is used when heat is absorbed by a reaction, thus leaving the surroundings colder

What volume of ammonia (NH3) will react completely with 25.0 liters of O2? 4 NH3 + 3 O2 ---> 2 N2 + 6 H2O
Answer:
18,75 litres
Explanation:
4 NH3 + 3 O2 ---> 2 N2 + 6 H2O
n (NH3) : n (O2) = 4 : 3
<=>
V (NH3) : V (O2) = 4 : 3
Hence, V(O2) = 3 × V (NH3) ÷ 4 litres
V(O2) = 3 × 25.0 ÷ 4 litres
V(O2) = 75 ÷ 4 litres
V(O2) = 18,75 litres

Does transfer RNA perform its function in the nucleus or cytoplasm? Explain.
Answer:
Explanation:
Although tRNAs participate in the essential function of protein translation in the cytoplasm, tRNA transcription and numerous processing steps occur in the nucleus.
Transfer RNA carries amino acids to the ribosome and adds them to the growing protein, copies the coded message from the DNA in the nucleus and carries the message to the ribosome in the cytoplasm.

A molecule of glucose is comprised of 6 atoms of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen.
According to the information given above, what is the molecular formula of glucose?
Answer:
C6H12O6 the third choice
According to the given information , the molecular formula or the chemical formula of glucose is C₆H₁₂O₆.
What is chemical formula?Chemical formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols of elements. It also makes use of brackets and subscripts.
Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form is called empirical formula.
It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.
There are four types of chemical formula:
1)empirical formula
2) structural formula
3)condensed formula
4)molecular formula
