Cyanobacteria are oxygenic photosynthetic bacteria. They harvest the sun's energy, absorb carbon dioxide, and emit oxygen. Like plants and algae, cyanobacteria contain chlorophyll and convert carbon dioxide to sugar through carbon fixation. ... Cyanobacteria are found in various land biomes and aquatic environments.
this blood type is A as it contains antigen A which reacts with anti A

2nd statement is true.</h2>
Explanation:
Chromosomes are made up of genes and a gene is made up of two copies of alleles. If an organism has two different types of alleles on its chromosomes then it's a hybrid organism else we call it a pure organism/trait.
- Gene could be dominant or recessive.
- A phenotype is the expression of a trait.
- As 'tall' gene is considered to be dominant so so pea plant with even a single copy of 'tall' gene will have a tall phenotype.

Although photosynthesis can happen in different ways in different species, some features are always the same. For example, the process always begins when energy from light is absorbed by proteins called photosynthetic reaction centers.</span>
