As means of locomotion, bacteria possess flagella.
Chemical digestion involves breaking down the nutrients into smaller cells
Physical digestion is using physical movements such as chewing and swallowing
so if you look up things that can cause an asthma attack it will also show that viruses and bacteria are a cause. with asthma you lungs could already be inflamed as well as your air way wich makes it harder to breath. when you have c-19 it will inflame your lungs even more so it makes it even harder to breath given an asthma attack. more asthma attack now are probably caused by c-19 because it is all over the place and the percent of asthma attack by virus has dramatically increased.
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.
It is true that r-related species have a short life span and an early reproduction cycle. R-related species also known as r-strategist have a short and simple life span. Due to their simple life span, their nutrient exchange rate with the environment is rapid. Unlike K-selected species, they have the ability to reproduce at a young age. They reproduce a large number of off-springs, but many of their off-springs tend to die before attainment of their reproductive age.
