What prediction can you make about softness of potassium and vigor of its reaction with water?
Answers
Answer:
Chemical properties of the alkali metals
Atoms of group 1 elements all have one electron in their outer shell. This means that the alkali metals all have similar chemical properties.
Reactions with water
The alkali metals react with water to produce a metal hydroxide and hydrogen. For example, sodium reacts with water:
Sodium + water → sodium hydroxide + hydrogen
2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
Sodium hydroxide is an alkali. It is a base that dissolves in water to form an alkaline solution. This solution:
has a pH greater than 7
turns universal indicator solution blue or purple
Hydrogen gas is also produced. With very reactive metals such as potassium, the energy of the reaction causes the hydrogen to burn as the reaction takes place.
Explanation:
Answer:
potassium reacts rigorously with cold water. potassium is a soft metal. we can predict that potassium is a highly reactive metal.

In the human body, is every organ a part of only one organ system? Or are some organs a part of two or more organ systems? A. Every organ is a part of only one organ system, which is necessary because organ systems work independently of one another. B. Every organ is a part of only one organ system, although organ systems often interact with one another. C. Some organs are a part of two or more organ systems. For example, the heart is a part of the circulatory and digestive systems. D.
Answers
C
[From ck12.org] "An organ can be part of more than one organ system. For example, the ovaries produce hormones, which makes them a part of the endocrine system; the ovaries also make eggs, which makes them a part of the reproductive system as well."
How are DNA and proteins related
Answers
Answer: Carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene
Answer:
The significance of DNA is very high. The gene's sequence is like a language that instructs cells to manufacture a particular protein. An intermediate language, encoded in the sequence of Ribonucleic Acid (RNA), translates a gene's message into a protein's amino acid sequence. It is the protein that determines the trait.

C. a reversal of direction in the prevailing winds over the Atlantic Ocean
D. a slight increase in the salinity of the Atlantic Ocean
Answers
Answer:
It constitutes the northeastward extension of the Gulf Stream; the latter issues from the Gulf of Mexico and gradually emerges as the North Atlantic Current in mid-ocean. It is composed of several broad currents with speeds of about 0.2 knots, as compared with the Gulf Stream's rather concentrated flow at 1 to 6 knots.

The correct answer is D i.e. krebs cycle occurs in mitochondria.
what is mitochondria?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP)
what is krebs cycle?
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).

How does the Golgi Body and Plasma membrane work together ?
Answers
Answer/Explanation:
The Golgi body is a system of flattened sacs that is involved in the packaging, modification, and transport of proteins. It is particularly important for proteins that have to be transported outside of the cell.
Proteins from the Golgi that are to leave the cell are transported in vesicles. When they reach the membrane, the vesicles fuse with it and release the proteins outside of the cell
