Answer:
plantea
Explanation:
because it is able to preform photosynthesis
The organisms which appeared on earth first was bacteria.
<u>Explanation:</u>
- The first-ever living organism on Earth was a bacteria known as cyanobacteria. It is believed by scientists that it first formed around 3 billion years ago.
- When the Earth was first formed, it was inhospitable for a long time until 3.8 billion years ago approximately, the core cooled down and the level of oxygen had risen. This, along with photosynthesis resulted in the formation of Cyanobacteria.
- These organisms were capable of carrying out the process of photosynthesis by which they prepared their food. These were known as common ancestors. All the living organisms thereafter are known to be their descendants.
Answer:
The correct answer is "Nitrogen will only become available to other, nearby plants when the nodules or the nitrogen-fixing plant itself dies".
Explanation:
Nitrogen fixing bacteria maintain a symbiotic relationship with plants. Bacteria performs nitrogen fixation providing the plant with ammonia, while bacteria has a safe place and nutrients to prosper. This relationship is very intimate because it occurs at the root hair of the plant at structures called nodules. Therefore, nitrogen will only become available to other, nearby plants when the nodules or the nitrogen-fixing plant itself dies
Answer: the correct answer is D 4, 3, 5, 2, 1
Explanation:
the correct steps in RNA synthesis are:
4) The polymerase finds a promoter region.
3) Several DNA bases uncoil, forming a stable complex.
5) A Mg + 2 dependent DNA isomerization occurs.
2) Template specific rNTPs are linked.
1) A nucleophilic attack of the 3'OH group of the first nucleotide occurs on the α-phosphate group of the second nucleotide 5 'triphosphate.
