I'm pretty sure that cells contain genes inside them.
Answer:
its affected by the number of chromosomes they have
A. Natural Selection. This is because the weeds that are not resistant to it die out before they can reproduce, but the resistant ones grow to maturity and then reproduce, passing down the resistance gene. Over time, the resistance gene would become a normal thing in weeds, while the non-resistant gene would not exist anyone, since the gene could not be passed on.
The above mentioned process is called as <u>Anaerobic respiration
</u>
<u>Explanation:</u>
All organisms need oxygen to produce energy but in some prokaryotes and eukaryotes they lack the presence of oxygen in their environment. Hence they have adapted a strategy called anaerobic respiration to break down the inorganic molecules to produce energy.
They use carbon dioxide and release methane as the by product. The process of glycolosis helps. All types of fermentation happens anaerobically here. It helps down to break down the fuels and produce energy. This energy is utilized for their life function.
They reproduce sexually and asexually
