Answer:
growth, reproduction, and sensitivity
Explanation:
<em>The characteristics of living organisms displayed by the object are growth, reproduction, and sensitivity.</em>
When the organism reacted by rolling over in response to touch from the learner, it was displaying sensitivity. Sensitivity has to do with the ability of living organisms to be sensitive to things such as touches.
When the object divided, it was displaying growth and reproduction that are characteristics of living organisms. Growth can be defined in this case as an irreversible increase in the number of cells and reproduction can be defined as the production of new individuals.
By dividing into 2, the object has increased its number of cells and has also produced a new individual.
<u>Hence, the characteristics of living organisms shown by the object are growth, reproduction, and sensitivity</u>
Answer:
Water vapor is a green house gas which absorbs the heat radiated from the earth's surface and keeps the earth warm. Clouds are formed by the condensation of water vapor in the atmosphere. They shield the earth from the sun by reflecting or scattering the solar energy and also trap the heat from the earth's surface. Thus both clouds and water vapor act like insulators from the sun and warms the planet.
Explanation:
When the earth’s surface get heated by the sunlight, some of the heat radiates back into the atmosphere and most of this heat is absorbed by gases in the atmosphere called green house gases. This process is called greenhouse effect, which keeps the earth warm. The green house gases mainly consists of carbon dioxide and water vapor.
Water vapor is formed through a process called evaporation. In this process, water from the ocean, rivers, and lakes evaporates to become water vapor using the energy from the sun. Water vapor also moves into the atmosphere by transpiration (plants) and sublimation (snow and ice).
The water vapor cools down and transforms into water droplets by a process called condensation, as it rises high in the atmosphere where the air is cooler. This water droplets that formed by condensation make up clouds. Low, thick cumulus clouds reflect majority of the solar energy straight back into space and thus cool the earth. High, thin cirrus clouds scatter the solar energy within the atmosphere and also trap the heat emitted by earth, thus warming the planet. Thus both clouds and water vapor act like insulators from the sun and warms the planet.
Answer: C
Explanation:
FOSSIL MOLDS are created when the sediment hardens, and the dinosaur bones fully disintegrate, leaving open spaces where the bones once were. ... FOSSIL CASTS are found when a fossil mold underground is filled with sediment to form a fossil in the actual shape of the animal bones!
I hope this helps :3
Answer:
C. Yes, Trisha should have a group of frogs in her experiment that is not exposed to any pesticide at all
Explanation:
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study (in this case, the effect of pesticide) from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All the groups must be similar in every variable that might influence the results, except for the study treatment.
- Control group: Frogs that are not exposed to any pesticide
- Treatment one: Frogs exposed to a certain concentration of pesticide
- Treatment two: Frogs exposed to an increased concentration of pesticides ...
And so, the number of treatment groups will depend on the different concentrations of pesticides Trisha wants to study.
All groups must belong to the same population and of course, to the same species. They must also be exposed to the same variables, excepting for the pesticide variable.
