Answer:
The question lacks the illustrative diagram, the diagram has been attached as an image.
The correct answer, according to the picture is A.
Explanation:
All cells undergo division (mitosis or meiosis). Meiosis reduces the chromosomal number of the daughter cells by half. According to the question, The female species of Myrmecia pilosula ant has diploid cells total number of 2 chromosomes.
At the metaphase stage of meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) aligns at the center/equator of the cell called METAPHASE PLATE. This alignment is done when spindle fibres attach to the kinetochores of the chromosomes.
Option A in the diagram depicts this arrangement of homologous chromosomes in the centre of the cell. Note that, each chromosome has replicated to form SISTER chromatids held together at the centromere. These chromosomes will be pulled apart in the next stage (Anaphase).
Option B depicts only one replicated chromosome
Option D depicts separation of sister chromatids (only one chromosome)
Option E depicts separation of sister chromatids of two chromosomes which occurs in the Anaphase of meiosis II
I think it’s will be A but not sure
Answer:
A) Occipital bone
Explanation:
Based on the scenario being described it can be said that the structure best demonstrated would be the occipital bone. This is a bone that forms in the base of the skull towards the back and around the spinal cord. Since the AP axial position projects the anterior structures downward, then it would allow for the occipital bone to be easily viewed without special equipment.
Flowering plants are the best of all plant bunches as far as their assorted variety. This gathering is typically alluded to as angiosperms on the grounds that, as their name infers, their seeds are encased in a carpel.
The angiosperms are vascular seed plants in which the ovule is prepared and forms into a seed in an encased empty ovary. The ovary itself is typically encased in a blossom, that piece of the angiospermous plant that contains the male or female conceptive organs or both.
Answer:
Explanation:
<em>Each trait of an organism is determined by discrete units called genes and individuals carry two alleles for each gene. (Mendel didn't actually discover genes though). Each gamete of an individual carries only one allele of each gene (this is Mendel's Law of Segregation).</em>
