Answer:
1.Natural Selection
2.Overproduction
3.Variation
4.Struggle for existence
The steps in the theory of Darwin should be performed in the following order: Overproduction, Natural Selection, Variation, and the Fight for Existence.
Thus, the following sequence can be used to number the steps in Darwin's theory, which involves variation where people within a population display innate variances in their attributes. This step is followed by overproduction, when an organism produces more children than the environment can sustain, resource competition results.
People within a population battle for survival because of overproduction and a lack of resources. The last step is natural selection, which involves people having advantageous mutations that suit their environment better have a higher likelihood of surviving and reproducing successfully.

What are the features of DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction.
DNA is a complex, long-chained molecule that contains the genetic blueprint for building and maintaining all living organisms. Found in nearly all cells, DNA carries the instructions needed to create proteins, specific molecules essential to the development and functioning of the body.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.

explain why oxygen and glucose need to be absorbed and waste products need to be removed
Answers
Explanation:
Oxygen and nutrients from food must be absorbed into the bloodstream to be delivered to cells for respiration. Waste materials such as carbon dioxide must be removed from cells into the bloodstream. Tissues contain capillary networks to allow these exchanges to occur at a cellular level.
Oxygen and glucose needs to be absorbed and waste products need to be removed for the proper functioning and maintenance of the body cells and systems.
Oxygen is an odor less and colourless gas that is needed by living organisms.
It is absorbed by living organisms because it serves as a source of fuel.
Glucose is a type of carbohydrate called monosaccharide which is gotten from food.
It is assimilated or absorbed into the body through the hormone insulin and serves as a source of energy.
Waste products of metabolism is removed from the body through the process of excretion. A typical example is the carbondioxide.
If Waste products are allowed to accumulate they cause poisoning which slows down vital chemical reactions.

The picture above is an example of what type of tissue?
Answers
Answer: Epithelial Cell
Explanation:
The given picture above is an example of epithelial tissue. Option 3 is correct.
Epithelial tissue is a type of tissue that covers the outside of the body and lines the inside of organs and cavities. It is made up of tightly packed cells that form a continuous sheet. Epithelial tissue has many functions, including:
Protection: Epithelial tissue protects the body from harmful substances and pathogens.Secretion: Epithelial tissue secretes substances such as mucus, sweat, and tears.Absorption: Epithelial tissue absorbs nutrients and other substances from the environment.Excretion: Epithelial tissue excretes waste products from the body.There are four main types of epithelial tissue:
Simple squamous epithelium: This type of epithelium is made up of a single layer of flat cells. It is found in the lining of the blood vessels, lungs, and kidneys.
Simple cuboidal epithelium: This type of epithelium is made up of a single layer of cube-shaped cells. It is found in the lining of the kidney tubules and the small intestine.
Simple columnar epithelium: This type of epithelium is made up of a single layer of column-shaped cells. It is found in the lining of the stomach, intestines, and uterus.
Stratified squamous epithelium: This type of epithelium is made up of multiple layers of flat cells. It is found in the skin, the lining of the mouth, and the esophagus.

Pablo and Johanna must complete a yearlong study for their biology course. After some discussion, they decide to compare dog diets. To test their hypothesis that the local veterinarian's special dog food mix will enhance growth and development, each student adopts a puppy from the local pound. Pablo plans to feed his goldendoodle the special diet, while Johanna plans to use generic dry kibble from the supermarket for her bulldog. Pablo and Johanna have too many ________.
Answers
Pablo and Johanna have too many independent variables.
In order to conduct an experiment, 3 kinds of variables are used. These are:
Dependent variable Independent variable Control variableA dependent variable is a variable that the experiment seeks to observe and measure, this variable is expected to change in value throughout the experiment and depends on other variables. An independent variable is one that the researcher changes throughout the experiment in order to see what effect it will have on the dependent variable. Finally, the control variable is the variable that remains the same throughout the experiment in order to limit the influence they will have on the outcome. If the value we wish to measure changes, the presence of control variables helps to narrow down and correctly credit the cause of this change, leading to a valid experiment.
In the situation given, Pablo and Johanna have too many independent variables. The dependent variables that Pablo and Johanna wish to measure are dog growth and development. The independent variable is the one they change in order to see what effect it will have on the dependent variable, in this case, the dog food. However, the experiment would not be valid because the breed of dog should be a control variable to ensure correct data, given that different breeds of dogs grow and develop at varying rates. This variable is instead an independent variable in this given experiment, given that it changes between the two groups and will affect the outcome.
