Answer:
The dependent variable is the biological sex of the alligator hatchling.
Explanation:
A hypothesis is essentially a suggested explanation for a specific phenomenon. These hypotheses attempt to offer well-tested reasons for certain observations through experiments.
Experiments are usually carried out under a variety of different conditions to test various hypotheses. To ensure reproducibility, accuracy, and validity of results, several factors must be identified when planning experiments.
For instance, various independent variables are strictly altered and observed while controls are kept constant - this ensures validity and can indicate if the experiment was influenced by external factors. Here, the factor being changed or tested is the temperature, and the factor being observed is the resulting biological sex of the organism.
Assuming that the affection is a recessive trait caused by a single diallelic gene, the percentage of the population that possess the heter0zyg0us advantage is 32%.
<h3>
Available data</h3>
- 1000 of African people population
- 4% of the population is born with sickle cell anemia
100% of the population -------------------- 1000 individuals
4% of the population with anemia------- X = (4 x 1000) / 100 = 40
0.04 is the frequency of individuals with sickle cell anemia.
Assuming that the affection is a recessive trait caused by a single diallelic gene, we can get the allelic frequency as follows.
- The genotypic frequency is q² = 0.04
- The allelic frequency is q = √0.04 = 0.2
Having the recessive allelic frequency, we can get the dominant allelic frequency, by clearing the following equation,
p + q = 1
p = 1 - q
p = 1 - 0.2
p = 0.8
So, the allelic frequencies are
p = 0.8
q = 0.2
To get the heter0zyg0us frequency, we just need to replace the values
2pq = 2 x p x q = 2 x 0.2 x 0.8 = 0.32
The frequency of the heter0zyg0us genotype is 0.32 = 32%.
32% of the population possess the heterozygous advantage.

The smallest item in the list would be organelles. Organelles are tiny structures within a cell, that help it to function. Example of organelles are-- nucleus, mitochondria, cell membrane to name a few. Cells are the basic unit of structure and function of all living things, therefore, cells would have to be placed second. They are microscopic. A group of similar cells that work together to perform a specific function, is known as a tissue. Therefore, tissue is next largest. Examples of tissues include, muscle tissue, epithelial tissue, adipose tissue. When different types of tissues work together to perform a function in the body, this group of tissues forms an organ. An example of an organ is the heart. Inside the heart are many types of tissue-- cardiac muscle,nerve, blood, connective, etc. The job it performs is to pump blood. When various organs work together to perform a specific function in the body, this makes up a system. An example is the circulatory system. In this system are many organs that work together. Arteries, veins, capillaries and heart are all part of the circulatory system. Its job is to circulate blood containing nutrients and oxygen to cells and to pick up cellular wastes. All the systems of the body comprise the organism. An organism is a living thing. It can be as tiny as a microbe, or a complex as a human. When referring to a multicellular organism, the correct order from smallest to largest is-- organelle, cell, tissue, organ, system, organism
