Answer:

This question is incomplete, the complete part is as follows:

This equation is unbalanced. Which of the following is the correct balanced equation for this reaction?

A. 4Fe + 3O2 → 2Fe2O3

B. 3Fe + 4O2 → 2Fe2O3

C. 2Fe + 4O2 → 3Fe2O3

D. 3Fe + 3O2 → 4Fe2O3

E. 4Fe + 4O2 → 3Fe2O3

The answer is A. 4Fe + 3O2 → 2Fe2O3

Explanation:

This question involved a chemical reaction between iron element (Fe) and atmospheric oxygen (O2) to produce iron oxide. The equation is given as follows:

Fe + O2 → Fe2O3

However, this chemical equation is NOT balanced and not in accordance with the law of conservation of matter. To balance this equation, we have to make sure that the number of atoms of each element on the reactant side is equal to that on the product side. Hence, we use COEFFICIENTS. The balanced equation is given below;

4Fe + 3O2 → 2Fe2O3

Answer:

Oxygen; food; adenosine triphosphate (ATP).

Explanation:

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells, so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).

All living organisms such as plants and animals require energy to function properly (life activities). The cell organelle where energy from nutrients are released is generally referred to as mitochondria. Animals and plants retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.

This ultimately implies that, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Generally, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe (respiratory system) while glucose is absorbed by the body when they eat (digestive system).

Hence, the respiratory system brings in oxygen and the digestive system breaks down food so that both substances are available to cells to make adenosine triphosphate (ATP).

Answer:

DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments

Explanation:

Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., BamH), or blunt ends, where the resulting strands are of the same length (e.g., HaeIII). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.

Explanation:

According to the graph given the number of algae is represented on the y axis while the month of the year is represented on the x - axis of the graph. The change in the number of algae from February is clearly depicted by an upward slope along the y-axis which means that there is continous increase in the Number of algae in the lake during this period, that is between February to June . It could also be seen that around June the optimal number of algaae is achieved as the number of algae tend to fall as we move beyond June.

I think you forgot to add the picture

Answer:

The answer would be DNA.

Answer:

Crust, mantle and core.

Water availability.

Volcanic eruptions.

Explanation:

The main similarities about Early earth and Modern earth is their layers of soil such as crust, mantle and core means that the both  Early earth and Modern earth are made up of these three layers. At that time water is present in huge amount while on the other hand, in Modern earth water is also present in large amount as compared to land. Volcanic eruptions occurs in both early and Modern earth.

Answer:

Answer: B

Explanation:

Evolution has changed the phisical atributes of all animals

Answer: mitosis

The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.

Answer:

Mitosis

Explanation:

When a eukaryotic cell divides asexually, the nucleus and its genetic contents must divide too, in a process called mitosis. Both haploid (n) and diploid (2n) cells can divide asexually, at which time their nuclei divide mitotically.

Explanation:

There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.

Answer:

The cell will shrink because water can move in but proteins cannot move out.

Explanation:

Since the egg membrane is semi-permeable, water can move in but proteins cannot move out. If a naked egg is placed in the corn syrup the egg will shrink. This is also due to osmosis, but in the opposite direction. The corn syrup is mostly sugar.
