Answer:
n+1; n+1; n-1; n-1
Explanation:
Separation of homologous chromosomes during anaphase I result in a reduction of the chromosome number to half in the daughter cells of meiosis. If two homologous chromosomes of a pair fail to separate from each other, they both will move to the same pole. In this case, one daughter cell of meiosis I will have both the homologous chromosomes of a pair (n+1) while the other one will lack it (n-1). Meiosis II in these two daughter cells will form a total of four cells. Two of the daughter cells will have one extra chromosome (n+1) while the rest two will lack one chromosome from the haploid set (n-1).
The mineralized impression of the organism left in the sediment is called a mold. The mineralized sediment that fills the mold recreates the shape of the remains. This is called a cast
The right answer is Light independent reactions require the energy gathered in the thylakoids.
* The dark phase corresponds to the phase of assimilation of CO2 which uses the energy molecules produced during the clear phase and which is carried out cyclically. This cycle is called the Calvin cycle and it takes place in the stroma of the chloroplast.
The assimilation of CO2 is done in four main stages, the first three of which take place within the Calvin cycle:
-CO2 fixation (carboxylation).
-Carbon reduction fixed.
-Regeneration of the CO2 acceptor.
-Synthesis of sugars.
* A thylakoid, or thylakoid membrane, in a chloroplast, is a flat membranous sac containing chlorophyll, or in other words, it is a cell membrane within the plant chloroplast that photosynthesizes. The thylakoid of a bacterium is also called the chromatophore.
A thylakoid is a membrane compartment within chloroplasts and cyanobacteria. They are the place of light-dependent reactions of photosynthesis. The thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen (in the biological sense).
The economy moved to growth due to the infrastructure activities, the main driver of economy is tourism.
The answer is radioisotopes as this has the ability of
breaking molecules apart and aside that, it has the ability of destroying cells
and as well as having to damage living tissues in the body because these are
isotopes that are unstable.
