Crossing over between two chromosomes
Anna007 [38]3 years ago

Answer:

Crossing-over

Explanation:

During Prophase I, which is the first division stage of meiosis I, homologous chromosomes pair up with each chromosome aligning with its homologue partner to form a TETRAD structure. At this stage, segments of each homologous chromosome break and get refixed interchangeably i.e trade parts. This process is called Crossing-over or RECOMBINATION

Crossing-over is the process whereby two chromosomes of a homologous pair (non-sister chromatids) exchange equal segments with each other to form two recombinant chromosomes.

Crossing-over accounts for genetic variation due to the swapping of genetic material. Some of the daughter cells receive daughter chromosomes with recombined alleles. Due to this genetic recombination, the offspring have a different set of alleles and genes than their parents do.

Answer:

Explanation:

Alkali metals (rarely 'Hydrogen and the alkali metals')

Alkaline earth metals (in old chemistry this name applied only to Ca and its congeners)

Icosagens (unofficial name; aka Boron group; rarely Earth metals)

Crystallogens (unofficial name; aka Carbon group; rarely Adamantogens[a] or Merylides[b])

Pnictogens

Chalcogens

Halogens

Noble gases (rarely Aerogens). The Group name may have to be changed to the “Helium group” since oganesson is not expected to be noble.

Degger [83]

Answer:

Predators are an important part of a healthy ecosystem. Predators remove vulnerable prey, such as the old, injured, sick, or very young, leaving more food for the survival and success of healthy prey animals. Also, by controlling the size of prey populations, predators help slow down the spread of disease.

VladimirAG [237]

i believe that the cell will expand because there is less sugar in the water. if you were to add more sugar into the water, then the cell will shrink in size because sugar and salt is the same thing if you add it in water.
