If this is the picture you are talking about, the right answer is non-disjunction
Non-disjunction is the non-separation of homologous chromosomes at the time of cell division which results in the formation of ova or spermatozoa leading to an abnormality in the number of chromosomes of the egg thus fertilized by the spermatozoa.
The fertilized egg consists of either a single chromosome, what is called monosomy, or, conversely, three chromosomes, this is called trisomy. While naturally, the fertilized egg has a single pair of chromosomes.
Answer:
The mechanism is natural selection.
Explanation:
Natural selection is the mechanism that these air-breathing fishes have gone through to survive. This mechanism allows species to survive and reproduce due to differences in the phenotypes of every individual in the specie, throughout the time the heritable traits that every individual inherits changes according to the environment and the characteristics of its ancestors.
Answer:
classifying organism
Explanation:
the main criteria for classifying organisms into five kingdoms are complexity of cell structure body organization the mode of nutrition lifestyle and phylogenetic relationship this system consists Monera,protisa,fungi,plantae,amimalia
Answer: the answer is C) Pea plant epidermal (leaf) cells have 7 chromosomes.
Explanation: plants have 16 chromosomes
Green plants need water (H2O) and carbon dioxide (CO2) for the process of photosynthesis.
Although CO2 has carbon, it's inorganic (there are some chemistry rules for what compounds are organic/inorganic, but I won't talk about them here).
