Answer: Convection
Explanation: Cold water sinks because it is more dense than warm water.
Warm water rises because it is less dense than cold water.
Answer:
The answer is natural selection
Explanation:
Answer:
Independent variable: ALTITUDE
dependent variable: GROWTH OF PLANTS
Confounding variable: STOREYS OF THE BUILDING
Explanation:
In an experiment, the basic components i.e primary variables that an experiment should contain, are the independent and dependent variables.
- The independent variable is the variable that is changed or manipulated in an experiment. In this experiment, the ALTITUDE of the plant is the independent variable.
- The dependent variable is the variable that responds to changes to the independent variable. It is the variable measured in an experiment. In this case, the dependent variable is the GROWTH OF THE PLANTS.
- The confounding variable is a variable that has an extra influence on the outcome of the experiment. In other words, the confounding variable has an impact on the dependent variable. In this case, the confounding variable is the STOREYS OF THE BUILDING.
Blood vessels visible in the posterior view of the heart include the Superior and inferior vena cava and the pulmonary veins. The superior vena cava and the inferior vena cava drain systemic venous blood into the posterior wall of the right atrium. The pulmonary veins transport blood from the lungs back to the heart and are best seen in posterior view of the heart. Other features visible in the posterior view include, right and left atrium, right and left ventricle, aorta, aortic arch, pulmonary veins and arteries, coronary sinus, coronary artery and posterior interventricular artery.
Answer:
Chracteristics reffers to some organisms from kingdon protista;
Eukaryotic, Mostly Unicellualar, Aquatic, Posses mitochondaria, Parasitism, Asexual reproduction, Autotrophic, Heterotrophic.
Explanation:
Kingdom protista in one of five kingdoms and the term protista is derieved from "prortistos" meaning "the very first". The protists are considered as first eukaryotic life on earth.
Protistsa includes the Eukaryotic predominantly unicellular organisms. Protists are eukaryotic organisms and they cannot by classified as fungi, Plants or animals due to their chracteristics.
