Iron is with one kind of atom that combines with oxygen from the air to form rust (iron oxide). Rust contains two types of atoms, which means it is .
Answer:
A compound
Explanation:
A compound is a substance (pure) that contains two or more different types of atoms chemically combined together. In other words, a compound is formed from the chemical combination of two or more elements.
According to this question, iron (Fe) is an element with one type of atom that combined with oxygen in the atmosphere to form iron oxide known as RUST. This is primarily what happens when a ironic substance is said to RUST. Rust is a combination (chemical) of two different kind of atoms i.e. iron and oxygen, hence, it is a COMPOUND.

When Paul Hopkinsberger swam the English Channel he had to train and he had to gain weight. What is it called when he or any other athlete runs out of the carbohydrates stored in the liver and the muscle and must start burning fat as their energy source?
Answer:
Not exactly sure this is right .Bonking, or “hitting the wall” as it is also known, is a well-known phenomena among marathon and ultramarathon runners which occurs when your body runs out of sugar to burn. Sugar, stored in your liver and muscles bound into large chains called glycogen, is the prime fuel for a distance runner.

A small group of deer are forced to leave the herd in search of a new habitat with more food. If the allele frequencies of the small group is identical to that of the large population, which of the following statements apply?
Read this question carefully!
1Points
A
Genetic drift has not occurred.
B
The bottleneck effect has happened.
C
The two groups will become different species.
D
The genetic variation of each group will be altered.
Answer:
the genetic varation of each group will be altered
In the case when the allele frequencies of the small group should be same to the large population so here the genetic variation for each group should be changed.
What is genetic variation?It is the variation that shows the presenting of the differences with respect to the sequence of genes lies between the individual organism with respect to the species. Since the allele frequencies of the small group should be same to the large population so here the genetic variation for each group should be changed.

does anyone know the answer??! HERE IS THE Q:
In pea plants, green peas are dominant to yellow peas. What would be the phenotypic percentages of the offspring that would result in a cross between a green heterozygous pea plant and a yellow pea plant? *
50% Gg, 50% gg
100% Gg
50% green, 50% yellow
100% green
Answer and Explanation:
Here is the given information:
Green peas are dominant, so we will put them as capital G.
Yellow peas are recessive (meaning they don't show if there is a dominant allele - trait), so we will pit them as lowercase G.
A Green Heterozygous (different, in this case, has both G and g, or Gg) pea plant.
A Yellow pea plant (will have both lowercase g, or gg).
To find the phenotypic percentages, we make a chart and solve.

So the correct answer should be among the following formulations:
Cube #1 to Cube #3
Cube #2 to Cube #1
Cube #2 to Cube #4
Cube #4 to Cube #3.
Heat, defined as a sort of energy transfer as well as the distinctive energy of a degree of freedom. Therefore, Cube #1 to Cube #3 and Cube #2 to Cube #4 are correct.
What is thermal energy?The word "thermal energy" is being used interchangeably in engineering and physics. It can relate to a variety of distinct physical notions.
Internal energy as well as enthalpy of a body of radiation and matter are examples of these; heat, defined as a sort of energy transfer (as does thermodynamic work); as well as the distinctive energy of a degree of freedom are examples of these. Cube #1 to Cube #3 and Cube #2 to Cube #4 describes the most likely flow of thermal energy in this situation.
Therefore, Cube #1 to Cube #3 and Cube #2 to Cube #4 are correct.

skin infection.
homeostatic imbalance.
Answer:
Damage to the skin or deeper tissues caused by sun, hot liquids, fire, electricity, or chemicals.
The degree of severity of most burns is based on the size and depth of the burn. Electrical burns, however, are more difficult to diagnose because they're capable of causing significant injury beneath the skin without showing any signs of damage on the surface.
