Answer:
The correct answer will be option E.
Explanation:
The features given in the question are the characteristics features of the group of bacteria belonging to Cyanobacteria.
These Cyanobacteria are the prokaryotes which are capable of synthesizing the food through a process called photosynthesis. These bacteria use sunlight as their energy, use water and air to synthesize food. They under anaerobic condition synthesize the nitrogen in special structures called heterocyst, a characteristic feature of cyanobacteria.
Thus, the features given in the question are:
1. contain photosystems to carry out photosynthesis.
2. producing oxygen
4. contain phycobilins
6. Hetrocysts: nitrogen-fixing structures.
7. The ancestor of plant chloroplasts.
Thus, option E is the correct answer.
Answer:
C
Explanation:
it just makes the most sense. A- hide does not relate to the word detect and is rather a antonym.

Answer:
alfa, beta and gamma
Explanation:
Rutherford studied the three types of radiation.c In the case of alpha radiation, it is composed of two protons and two neutrons, the alpha particle is a nucleus of the element helium, which has high mass and short range.
In the case of beta radiation, it travels distances of up to one meter and consists mainly of electrons.
In the case of gamma radiation, it is composed of high-energy photons (it does not have my electrical charge or resting mass).
