Modern taxonomists primarily use which of the following to classify living organisms

1 answer:

3 0

The modern taxonomists classified organisms on the general basis of evolutionary, morphological, and genetic traits

Explanation:

Evolutionary relationships provides the phylogeny of evolutionary ancestors and descendants
Homologous structures are structures which look the same but perform different functions , like bones of a human leg compared to bones on a bird's wing
Analogous structures have different structure but same function like an insect’s and a bird’s wing
Embryo developmental pattern and similar relationships
Similarities in DNA and protein sequencing in related organisms

The above basis provided modern taxonomists to classify organisms according to the various disciplines like Genetics, Cytology, Embryology, Physiology, Anatomy and many more.

Hypothesis:

AleksandrR [38]

Answer:

Objective(s):

In your own words, what was the purpose of this lab?

In this lab report, the purpose is that hamsters carry traits fro parents.

Hypothesis:

In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.

Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

All short fur

Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

Some short and some long

Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.

All long fur

Procedure:

The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.

Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation.

Test variable (independent variable): Outcome variable (dependent variable):

Data:

Record the data from each trial in the data chart below. Be sure to fill in the chart completely.

Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

1. Which genotype(s) and phenotype for fur length are dominant? FF

2. Which genotype(s) and phenotype for fur length are recessive? ff

3. If you have a hamster with short fur, what possible genotypes could the hamster have? It would probably be Ff or a ff

4. If you have a hamster with long fur, what possible genotypes could the hamster have? It would be Ff or an FF

5. Did your data support your hypotheses? Use evidence to support your answer for each test.

◦ Test One:? ◦ Test Two:?

◦ Test Three:?

6. Which hamsters are the parents of the mystery hamster? Include evidence to prove that they are the correct parents.?

Answer: Maybe if you knew the def's you could answer it.

Initial Decay – Bacteria located mainly in the lower intestine begin decomposition, giving a greenish color to the lower abdomen. Stage 2: Putrefaction – Bacteria grow throughout the body, releasing gases, including cadaverine, which in turn bloat the body and cause unpleasant odor.

putrefaction

the process of decay or rotting in a body or other organic matter.

Black putrefaction occurs, which is when noxious odors are released from the body and the parts of the body undergo a black discoloration. 2 weeks: The abdomen is bloated; internal gas pressure nears maximum capacity. 3 weeks: Tissues have softened. Organs and cavities are bursting.

Fermentation occurring in putrefaction and apparently in the digestion of herbivorous mammals in which butyric acid is produced by certain chiefly anaerobic bacteria acting upon various organic substances (such as lactic acid or butter)

A dry body will not decompose efficiently. Moisture helps the growth of microorganisms that decompose the organic matter, but too much moisture could lead to anaerobic conditions slowing down the decomposition process
