GREYUIT [131]1 year ago

Bacteria need an optimum temperature for their growth, so this is the reason why we might not see as much bacterial colonization of microbes from human saliva on plates cultured at 25 °C versus plates incubated at 37 °C.

Why do bacteria only grow at certain temperatures?

  • The main justification for incubating bacterial cultures at various temperatures is that different temperatures favor the growth of particular bacteria.
  • Most infections and typical ambient bacteria are classified as mesophiles, which thrive in temperatures between 20 and 40 degrees Celsius.
  • An optimum temperature is required for the enzymes to show their activity, and for the division also many enzymes are involved in the process. So, the bacterial culture can be seen at a particular incubation temperature only.

Which best describes the role of a primary consumer in a food web?
Soloha48 [4]

Answer:

Herbivore that feeds on producers

Explanation:

The producers are plants at the bottom of the food web. These are eaten by herbivores, that are the primary consumers.

Herbivores themselves are consumed by carnivores, which are secondary consumers.

Sometimes, these carnivores can be consumed by top predators, like a shark, snake or eagle.

<u>Options and why they are right/wrong</u>

Carnivore that feeds on producers  - carnivores do not feed on producers

Herbivore that feeds on producers  - this is correct

Herbivore that feeds on primary consumers  - primary consumers are animals and herbivores do not eat animals

Carnivore that feeds on primary consumers - this would be a secondary consumer

Which of the following correctly describes Metaphase?
natima [27]

During the metaphase, chromosomes are taken to the equatorial plane, were they randomly line up. Option B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.

<h3>What is the metaphase?</h3>

Metaphase is one of the cell division stages that follows the prophase and precedes the anaphase.

During this phase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes randomly line up.

Once aligned, each chromatid joins with a microtubule of opposites poles and gets ready to go through the anaphase. Sister chromatids are held together until they reach the Anaphase.

Since chromosomes in this stage are well defined and can be observed in detail under the microscope, they are used to create karyotypes and identify chromosomal abnormalities.

These chromosomes have the typical X shape.

Among the options, the one that correctly describes the metaphase is Option is B. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.

With this, the energy from the sun gets trapped within a chemical bond and still relates to photosynthesis in plants.
