After the G2 phase, the cell goes thru another growth period. The cell will gather energy in order to prep for whats coming: Mitosis. The first phase of mitosis is Prophase. During Prophase, the chromatin fibers condense and shorten to chromosomes that can now be seen with aid from a light microscope. Microtubules also appear and prepare to hold sister chromatic im correct alignment for separation. Metaphase is the second phase. Microtubules align sister chromatids at the exact center of the mitotic spindle aka metaphase plate. The following step is Anaphase. The centromeres split, separating the 2 identical sister chromatids. Once the chromatids are separated, they are called chromosomes. Telophase comes after anaphase. It is the final stage of mitosis. The identical sets of chromosomes are now at opposite sides of the cell. The nuclear envelope now re-forms around each mass of chromosomes, nuclei reappear within each nucleus. After these phases, Cytokenisis occurs. This is the division of the cell's cytoplasm and organelles into 2 cells. A cleavage furrow is formed during Anaphase.
Answer:
They both were a downfall
Explanation:
The best answer is D.
Nothing would happen because the disease is genetic. It is inherited and not acquired and its cause has absolutely nothing to do with malaria. The only thing that malaria does is that it can cause a dangerous medical condition called sickling crisis in a person with the sickle cell disease which does not occur in people who do not have sickle cell disease even if they get infected with malaria.
The cause of sickle cell disease is a mutation in the Beta chain of the protein molecule called hemoglobin. The mutation causes the 6th amino acid called thymine in the beta chain to be substituted with another amino acid called valine. This change of a single amino acid causes the hemoglobin molecule to behave abnormally resulting in sicke cell disease.
C. a food chain accurately represents feeding relationships
Answer:
virus are obligate parasites. Viruses do not, however, carry out metabolic processes. Most notably, viruses differ from living organisms in that they cannot generate ATP.
