Hello!! Since there is no mention of weight in the question, I would assume that she is pregnant. Whenever someone's blood pressure is low, it is referred to hypotension. Whenever someone's blood pressure is high, it is referred to hypertension. I would say your best answer is A - She has hypotension because she is pregnant. I hope that is the right answer you are looking for. Have a great day!! :)
The assortment of homologous chromosomes during meiosis is random and generates genetic variation, the raw material for evolution.
During metaphase I of meiosis, homologous chromosomes are lined up at the equator plate of the cell in order to be separated (assorted) in anaphase I.
The separation of homologous chromosomes during meiosis I is random. Daughter cells receive unique gene combinations from an original parent cell.
Subsequently, haploid cells got from two successive meiotic divisions fuse during fecundation to form a diploid (2n) zygote.
During prophase I, non-sister chromatids interchange genetic material by a process known as recombination. This genetic process also increases genetic variation in daughter cells.
In conclusion, the assortment of homologous chromosomes during meiosis is random and generates genetic variation.
The right answer for the question that is being asked and shown above is that: "B. birds have beaks adapted to break open hard shells." The adaptation would most likely be found in organisms living in the rainforest is that <span>birds have beaks adapted to break open hard shells</span>
Answer:
These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen. In fact, all the plants on Earth incorporate symbiotic cyanobacteria. For some untold eons prior to the evolution of these cyanobacteria, during the Archean eon, more primitive microbes lived the real old-fashioned way: anaerobically. These ancient organisms—and their "extremophile" descendants today—thrived in the absence of oxygen, relying on sulfate for their energy needs. But roughly 2.45 billion years ago, the isotopic ratio of sulfur transformed, indicating that for the first time oxygen was becoming a significant component of Earth's atmosphere,
