A body that does not produce much internal heat
Answer:
<em>Staphylococcus</em> is a gram negative bacteria that belongs under family Staphylococcaceae.The name is given as their body shape is spherical(Cocci).
Explanation:
The important characters of Staphylococcus are-
- <em>Staphylococcus </em>are facultative anaerobic organism.
- They are spherical in shape.
- As they are gram positive bacteria, thus the cell wall is prominant and easily stained with crystal violet and they are grown in bile salts.
- They are capable of producing coagulase enzyme that cause blood clot.
- These bacteria divides along two axes and thus form clump of bacteria.
Difference between <em>S. aureus</em> and <em>S.epidermis-</em>
- <em>S. aureus</em> is round in shape where as<em> S.epidermis</em> is spherical in shape.
- <em>S. aureus</em> is a opportunistic pathogen that cause different diseases like skin infection where as<em> S.epidermis</em> is non pathogenic bacteria.
- <em>S. epidermis</em> form white raised cohesive colony with 1-2 mm in diameter whereas, <em>S.aureus</em> form golden yellow color colony.
- <em>S.aureus</em> causes hemolysis when it is grown in agar plate whereas <em>S.epidermis</em> is not hemolyse in blood agar plate.
The answer is (A) Mitochondria have their own DNA molecules, separate from the rest of the cell's DNA.
The endosymbiotic hypothesis concerns with the presence of two special organelles, mitochondria and chloroplast within the eukaryotic cell. These two organelles have their own set of DNA that is different from the nuclear DNA of the eukaryotic cell. It is believed that a primordial eukaryotic cell was in a symbiotic relationship with mitochondria-like bacterium. The primordial cell eventually engulfed the mitochondria-like bacterium for ATP production to power itself.
Answer: Their genes are Recessive
Answer: Sea anemone and ctenophore both inherited tentacles from a shared ancestor population, but this population separated into different environments. In each environment, different types of tentacles evolved, which helped the populations survive.
Explanation:
most likely explains why both species have tentacles and why the tentacles are different is because sea anemone and ctenophore both inherited tentacles from a shared ancestor,
Then, this population separated into different environments and there was tye evolvement of different types of tentacles evolved, which therefore helped the populations survive.
