Crossing over contributes to genetic variation by exchanging chromosomal segments between non-sister chromatids of homologous chromosomes.

What is crossing over?

  • Crossing over is the exchange and recombination of genetic components between the homologous chromosomes.
  • This occurs in the pachytene stage of the meiosis-1 of the meiotic division.
  • Crossing over occurs with the help of an enzyme and the enzyme responsible for crossing over is called Recombinase.

Thus, crossing over contributes to genetic variation by exchanging chromosomal segments between non-sister chromatids of the homologous chromosomes.

Helga [31]
There is quite a lot, but the fact that both mitochondria and chloroplasts have their own circular DNAis what I would call "key" evidence. That is, these organelles are not "manufactured" by the cell (i.e., there are no "genes for mitochondria" in eukaryote genomes): like their ancestral bacteria, they reproduce by binary fission.

katrin2010 [14]

Answer:

response to stimuli / tropism

Explanation:

The plants and animals always respond to stimuli. It is an innate character of all living things. When a bright light falls on the eye, it closes immediately. This is responding to the stimuli. When someone touches the leaves of touch-me-not plants it closes its leaves due to the external stimuli.

The plants respond to the light. Because it does photosynthesis in the presence of light. Therefore, the leaves and branches of the plants always bend towards the light. This process is called phototropism.

Similarly, the roots of the plants move towards gravity under the ground. This is called geotropism.

Besides phototropism and geotropism, other types of stimuli are there - hydrotropism(response to the water), chemotropism(response to certain chemicals).

That's why the plants growing on the windowsill move towards outside where light comes.

chubhunter [2.5K]

Answer:

The animal cells get the organic compounds by eating plants. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together.
