The answer is: Carnivores
Organisms at the third trophic level are secondary consumers. These secondary consumers prey on the primary consumers which are animals that eat plants or herbivores. Secondary consumers are best described as carnivores because they don't eat plants. They only eat animals that consume plants like cows and chicken.
<span>To verify the purity of a
colony, a number of steps could be adopted. Pick the colony and dissolve it in sterile
water (approximately 5ml), streak in media again and incubate. Observe if it
produces pure colonies of the chosen organisms and if not, repeat the procedure
until pure colonies are produced. Additionally, one could perform additional tests
that categorize bacteria such as Gram staining. </span>
Answer:
During the asexual reproduction, bacteria can divide simply by binary fission in which one bacteria first replicate its genetic material and the cell divide in two daughter cells which are identical to the parent cell.
Asexual reproduction does not allow genetic variation therefore to get genetic variation bacteria can use conjugation, transformation and transduction process.
In conjugation, bacteria gets extra genetic material from other bacteria through sex pills. In transduction the genetic material enters into the bacterial cell through the virus then bacteria incorporate this genetic material in its genome.
In transformation, bacteria takes up the extra genetic material from it's surrounding. Therefore conjugation, transduction, and transformation helps bacterial to gain variation like as in sexual reproduction.
D. Chloroplast is only found in plant cells not in animal cells
<span>The nurse needs to note the outburst, and report it to her supervisor. Although this comment seems at the surface to be an admission of guilt, perhaps there are other unseen circumstances. For example, perhaps she is blaming herself for letting the child out of her sight, and the injuries were actually caused by another while the child was out of her vigilance.</span>
