Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.
When infected by a virus, a host cell produce many thousands of identical copies of the original virus. so the answer is B

Explanation:
The rate of photosynthesis increases withe increase in temperature. Photosynthesis like any other chemical reaction responds positively to an increase in temperature.
At high temperatures, enzymes that takes part in the photosynthesis can be destroyed. This is 20°C where enzymes are usually denatured.
- Photosynthesis is the process where green plants manufacture their food using inorganic substances from the environment.
- During photosynthesis, plants combines carbon dioxide with water and produces organic molecules and oxygen.
- Like any other chemical reaction, the reaction will proceed faster with an increase in temperature.
Hypothesis: If temperature is increased then the rate of evolution of oxygen gas increases because the rate of chemical reactions increases with increase in temperature.
Since oxygen is a by product of photosynthesis, we can quantify its rate of production as temperature increases.

Answer:Independent Variable
A variable that you (the scientist) changes and you have control over. The factor being tested in an experiment.
Dependent Variables
Factor(s) that change in response to other factors. It's what your measuring in your experiment to see whether or not the independent variable made an impact. This is what the scientist focuses their observations.
