Answer:

B. endosymbiosis

Explanation:

Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.

What will be the results in the F2 generation after a monohybrid cross?
Sedbober [7]

Answer: \dfrac34 dominants and \dfrac14 recessive.

Explanation:

Mendel's monohybrid cross is definied as

  • a genetic combination of two homogeneous genotypes.
  • One is <em>dominant(TT)</em> to other <em>(tt-recessive).</em>

Result in F1 generation: 4 dominant(Tt), 0 recessive (tt)

Result in F2 generation: 3 dominant(TT, 2Tt), 1 recessive (tt)

[If one T is present then we call it Tall (Donimant effect), if none then we call it dwarf]

The results in the F2 generation after a monohybrid cross: \dfrac34 dominants and \dfrac14 recessive.

Lionfish are native to the tropical waters of the Indo-Pacific. What conclusions can be made about the impact of climate change
Nata [24]

Answer:

The correct answer is - Climate change has restricted the habitat of lionfish. It has become an endangered species, reducing biodiversity.

Explanation:

As we know it is native to the tropical waters of the Indo-Pacific region. The change in the climate will increase the temperature of the water and this will lead to the restriction of habitat which lead to the reduction in the population of the fishes. As they live in the tropical climate they are habitual of warmer water and can not survive the climate change.
