The correct answer is: a. n+1, n+1, n-1, n-1
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis or meiosis. There are three forms of nondisjunction:
1. failure of a pair of homologous chromosomes to separate in meiosis I ,
2. failure of sister chromatids to separate during meiosis II, and
3. failure of sister chromatids to separate during mitosis.
As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.
The oxygen that we are all taught is a product of photosynthesis comes from what?
Answer:
Splitting of water to replace chlorophyll electrons.
Nuclear maturation encompasses nuclear envelope breakdown, meiotic spindle assembly, and chromosome segregation. Cytoplasmic maturation involves major changes in oocyte protein translation and cytoplasmic organelles and is poorly understood.
In the nematode Caenorhabditis elegans, sperm release the major sperm protein (MSP) hormone to promote oocyte growth and meiotic maturation.
Large translational regulatory ribonucleoprotein (RNP) complexes containing the RNA-binding proteins OMA-1, OMA-2, and LIN-41 regulate meiotic maturation downstream of MSP signaling.
To understand the control of translation during meiotic maturation, we purified LIN-41-containing RNPs and characterized their protein and RNA components. Protein constituents of LIN-41 RNPs include essential RNA-binding proteins, the GLD-2 cytoplasmic poly(A) polymerase, the CCR4-NOT deadenylase complex, and translation initiation factors.
RNA sequencing defined mRNAs associated with both LIN-41 and OMA-1, as well as sets of mRNAs associated with either LIN-41 or OMA-1. Genetic and genomic evidence suggests that GLD-2, which is a component of LIN-41 RNPs, stimulates the efficient translation of many LIN-41-associated transcripts.

Answer:
Option 3,
Explanation:
In the process of cellular respiration, the sugar is oxidised to convert into carbon dioxide , water and energy molecule ATP (Adenosine Tri Phosphate)
If the above chemical reaction is represented mathematically it will be as follows -
The above reaction is a balanced chemical reaction representing cellular reaction
Thus, option 3 is correct
The complete blood count or CBC is a pathological test, which measures the number of red blood cells (RBCs), white blood cells(WBCs), platelets and other vital compounds present in a definite amount of the blood.
The CBC allow detection of the presence of any ailment, which can affect the normal physiology of the blood.
Hence, the acronym for blood test that measures the number of RBCs, WBCs and platelets is CBC.
