Separate kingdoms but fossil evidence shows they have evolved from a common ancestor
DiKsa [7]3 years ago
3 0

Answer:

N the modern classification system birds are in a separate group from reptiles, but fossil evidence shows they have the same ancestry.

Explanation:

It is true that birds and reptiles are classified in different groups, since they present different anatomical, structural and biological differences, however these animals have several similarities, since they probably descend from the same ancestor.

It is well accepted in the scientific community that birds emerged from groups of dinosaurs, that is, that birds and reptiles were formed by the same ancestor. For many scholars, for reptiles to become a valid group, birds should be part of that group, but it was decided that mantles would be better in different groups.

Factors that influence the expression of human sexuality
mihalych1998 [28]
There can be a lot of factors that express sexuality. The origin would be its genes. The genetic make-up of the person what trait has passed on to an individual from his parents. Another factor is the environment. A person's sexuality can be influenced by social groups, home environment and from the media that he/she looks at.

What happens to the air that a emperor penguin breathes in?
enot [183]
Emperor penguins need lungs to breathe. In penguin lungs, air never stops. ... Once the air goes farther into the trachea it splits into two different directions into both lungs. To get the oxygen into the blood cells, it must come "within small distance of the penguin blood cells".

Deshaun is determining which sources are most appropriate for his research project. Which step of research process is he on? A.
guapka [62]

Answer:

3: Evaluate Your Sources D

Explanation:

Deshaun  is determining which sources are most appropriate for his research project. Here he can evaluate a variety of sources such as newspaper articles, magazines, journals, or books, and websites. So, it is important for him to make sure that he includes only authentic any valid information in his research.

So, he needs to evaluate his sources using several criteria like:

  • Accuracy
  • Scope / Relevance
  • Current/ up to Date
  • Objectivity
  • Reliability
  • Style
  • Functionality

Using these criteria he can evaluate his sources to choose the best and appropriate one for him.

Hope it help!

1. What are the independent and dependent variables in each of the experiments?
Dafna1 [17]
  • The independent variables are temperature, airflow, and light and the dependent variable in each of the experiments is evaporation.
  • The schematic representation in the diagram helps in the understanding of the setup for the experiments.
  • The level of temperature, the rate of airflow, and the intensity of light must be controlled in the experiments.
  • A person will not be confident in experiment 3 results as the temperature is the independent variable that alters the results of evaporation.

<h3>What are the four foremost factors of a managed test?</h3>

When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.

  • In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.

The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.

  • The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.

  • The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.

  • The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.

  • The flow chart for the increase in pressure affecting the evaporation is given in the image attached.
