If a homologous pair of chromosomes fail to separate during meiosis I, what will be the result?

Biology
1 answer:
BabaBlast [244]3 years ago
5 0

Answer: A) 2 gametes will have 2 of these chromosome and 2 will have 0 of these chromosomes.

Explanation: Meiosis is a division process in sex cells. Meiosis has two stages: In Meiosis I duplicated homologous chromosomes (one pair from mother and one pair from father) are separated in two daughter cells. Later those cells begin meiosis II where chromatids of each chromosome are separated in two daughter cells. If homologous chromosomes fail to separate during meiosis I, the result would be 2 diploid (contain two copies of that chromosome) gametes for that chromosome and 2 gametes without that chromosome.

Which of the following is not a sign of possible pest infestation?
Brrunno [24]

The right answer is smelly garbage.

Infestation is the penetration into the body of a parasite whose nature is not microbial.

smelly garbage is not synonymous of infestation, because the olfactory system only detected smelly metabolites of these microorganisms. This does not necessarily mean that the microorganism has managed to penetrate the body.

By cons other proposals are signs and tools for infestation (torn packaging with food leaking out, dead insect bodysuits, feathers, and fur).

What does a pyramid of biomass represent? A. Range of food webs found in one trophic level B. Percentage of energy that's passed
Klio2033 [76]

The pyramid of biomass represents a range of food webs found in one trophic level

A pyramid of biomass refers to graphical representation of biomass that is present per unit area of all the various trophic levels of the ecosystem.

<h2>Further Explanation</h2>

The graphical representation shows the relationship between biomass and trophic level that quantify the biomass that is present in each trophic level of energy community at a given period of time.

There are two types of pyramid of biomass, they include

  • Inverted pyramid of biomass  
  • The upright pyramid of biomass  

Inverted pyramid of biomass: a very good example of inverted pyramid can be seen in a case of pond ecosystem, where major producers in the ecosystem (mass of phytoplankton) will be lower than the mass of heterotrophs, such as insects.  

The upright pyramid: The first thing on the upright pyramid is the producers, such as plants. The plants are present at the bottom level of the pyramid and followed by consumers.

Within the pyramid, the highest level is occupied by the carnivores; they are the lowest quantified amount of biomass. In upright pyramid the total weight of the producers is far more than when the weights of all the consumers are combined.  

However, the main issues with the pyramid of biomass are that every trophic level of the pyramid seems to have more energy than it does.
