what are the answer choices
<span>The correct answer would be amoeba. So the amoeba consists of protoplasm and a nucleus. For an amoeba the nucleus is a major organelle, which is located centrally. As such a major organelle it naturally has a huge role, and that is that it controls reproduction (it contains the chromosomes) and many other important functions (including eating and growth).</span>
Answer:
B. Granulocyte
Explanation:
Granulocyte is the type of white blood cell with fragments in its cytoplasm. These fragments usually help in the digesting the cells of the foreign body(pathogenic organisms).
There are three main types of Granulocytes which are known as the Neutrophils, eosinophils, and basophils. They all perform variety of functions ranging from phagocytosis to cell lysis of foreign bodies.
<span>Early pre-cambrian period the atmosphere consisted only of nitrogen and carbon dioxide without oxygen.
<span>A
Prokaryotic cell does not contain a nucleus. It only contains one
chromosome and is a single-celled organism. It was the only form of life
on earth for millions of years. Examples of a Prokaryotic cell are the
different types of bacteria present today.
</span><span>Autotrophs
obtain energy by the process of photosynthesis. Any living organism
need energy to survive and autotrophs are no different. Two types of
autotrophs are present and they are Photoautotrophs and Chemoautotrophs.
The Photoautotrophs rely on the energy produced during the process of
photosynthesis and the Chemoautotrophs get their energy from most of the
inorganic substances. Phtoautotrophs actually get their energy from the
sunlight and then convert it into reusable form. In case of
Chemoautotrophs ammonia is an important source of energy for them.</span></span>
