B. If there were no greenhouse effect, liquid water would not exist on the surface of the Earth
D. The Earth has reached thermal equilibrium, emitting the same amount of energy into space as it absorbs from the Sun.
E. The more carbon dioxide there is in an atmosphere, the stronger the greenhouse effect will be
Explanation:
The greenhouse effect plays major role in the climate of our planet in diverse ways:
- it is responsible for the existence of liquid water on the surface of the earth.
- it allows the earth to reach an equilibrium with space in exchange of thermal energy.
- carbon dioxide concentration in the atmosphere has huge roles.
The greenhouse effects results from the abundance of greenhouse gases in the atmosphere. These gases are able to prevent long wave solar radiation from leaving the surface of the earth. When the gases interacts with the radiation, it produces heat that warms the earth surface. Examples of these gases are carbon dioxide, methane, water vapor e.t.c.
The warming of the surface helps to free freshwater trapped as ice and keeps it in the liquid form throughout.
In this exchange of energy, there is a balance between the amount of heat absorbed and radiated back into the atmosphere. As energy enters the earth, it is also radiated out into space. This helps to keep the earth temperature in balance.

Answer:
The organelle that conduct respiration for the cell is MITOCHONDRIA.
Explanation:
The cells of living organisms are made up of different organelles, each of the organelles have specific functions, which they perform. The mitochondria is the cell organelle that is responsible for carrying out respiration in the cells. Respiration involves the breaking down of glucose molecules in order to produce energy in form of ATP. Mitochondria is also called the power house of the cell because of its function of energy production.
Answer:Higher levels of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.

Answer:
Explanation:
As a microbiologist there are different methods are devised for characterization of microbes.such as Macroscopic analysis and microscopy method.
With the help of microscope the needed information about the individual cell such as individual cellular characteristics can be obtained, the magnification help to provide the features such as size, shape and motility of the microbes which helps to know the specific microbes characters.
When handling an unknown environmental microbe, with help of the cell characteristics of the microbes obtained using the microscope, the identity as well as metabolic characterization can be known such as the type of environment the microbes can survive in(aerobic or anaerobic), the source of food.
No growth was observed on the control plate.
The growth on the control plate indicates that the aseptic technique devised in the model was an adequate method for the prevention of the control plate from been contaminated.
Answer:
plasmolysis is the shrinkage of protoplast from the cell wall under the influence of a hypertonic solution.this can be observed by placing the fresh filament of spirogyra in a 10% solution of common salt.the cell undergoes exomosis.
