kow [346]

Answer:

Larva and pupa is present in complete metamorphosis while nymph is present instead of larva and pupa in incomplete metamorphosis.

Explanation:

Complete metamorphosis has four stages i. e. egg, larva, pupa, and adult while the incomplete metamorphosis has three stages i. e. egg, nymph, and adult. Grasshopper, dragonfly, cicada and cockroach have incomplete metamorphosis while ladybug , housefly, butterfly  and honeybee have complete metamorphosis. Both type of insects lay eggs and after hatching a baby insect comes out called larva. After sometime this larva transforms from immature to mature, this stage is known as pupa. After pupa, the insect converts into an adult which is ready for reproduction. Nymph is a stage that comes in place of larva and pupa in incomplete metamorphosis. in this stage, the insect is small in size and lack of wings but in adult stage the wings appear.

Explain character displacement, and provide an example.
nata0808 [166]

A line of indirect evidence of competition comes from the comparison between closely related species, whose population can be allopatric (geographically separated) or sympatric (geographically superimposed). In some cases, the allopatric populations of these species are morphologically similar and use similar resources. On the other hand, sympatric population, which are supposed to compete for resources, have body structures and use different resources. The displacement of characters is the tendency to have more divergent characteristics in sympatric populations of two species than in allopatric populations of the same two species.

An example of character displacement is the variation in size between populations of galapagos finches. Some of its populations are allopatric ( they live separately) and others are sympatric ( they live together). Peak size distributions they vary according to whether they are sympatric or allopatric.  They look more alike when they are allopathic than when they are sympatric. That is, the peak size character moves when species enter competition.

After two half-;ives (9 billion years) what percent of the orignal uranium remains?
Colt1911 [192]

The percentage of the orignal uranium that remains after two half-lives is 25%

<h3>Data obtained from the question </h3>
  • Original amount (N₀) = 100%
  • Number of half lives (n) = 2
  • Percentage remainig (N) =?

<h3>How to determine the percentage remaining</h3>

N = N₀ / 2ⁿ

N = 100 / 2²

N = 100 / 4

N = 25%

Thus 25% of the original sample remains

a phenol red sugar fermentation broth contains a generic complex growth media that most organisms can grow in, and a large amoun
Ugo [173]

Phenol red broth base is the media that is used to grow most organisms and a large amount of a potentially fermentable sugar.

For the purpose of microorganism differentiation, phenol red broth base is advised to ascertain the fermentation response of carbohydrates.

Gram negative bacilli can be recognised with it, particularly Enterobacteriaceae. It includes one carbohydrate, a Durham tube, peptone, and phenol red (a pH indicator) (glucose, lactose, or sucrose).

When a carbohydrate is utilised by an organism, an acid byproduct is produced, which causes the media to turn yellow. If the organism can use the peptone but not the carbohydrate, ammonia is produced as a byproduct, which raises the pH of the medium and colours it fuchsia.

A gas byproduct could be created once the organism is able to utilise the carbohydrate. If so, the Durham tube will become caught by an air bubble. Gas will not be created and no air bubble will emerge if the organism is unable to use the carbohydrates .
