That's the function of the nucleus.
The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. ... Ribosomes make proteins; therefore, the nucleolusplays a vital role in making proteins in the cell. Function of the Nucleolus. Ribosomes are made of two subunits, a large and a small
Answer:Bisexual flowers are complete flowers, containing both androecium and gynoecium in one flower. Therefore, bisexual flowers contain both stamens and pistils in the same flower. Hence, bisexual flowers are called hermaphrodite or androgynous flowers as well.
Explanation:
Answer:
1. Mitochondria
2. Chloroplast
3. the formation of eukaryotic cells
4. DNA
Explanation:
The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.
The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.
The evidence which supports their ar:
1. The same size of the organelles to the bacteria
2. The presence of the circular DNA of the organelles like bacteria
3. The similarity in the 30s and 70s ribosomal subunits.
Answer:
A
Explanation:

The right answer is B.
Cholera vaccination is only recommended for staff who have to intervene with patients in an epidemic situation. In all other cases, effective prevention is provided by good personal hygiene (washing hands) and food.
