Start of diseases such as skin cancer. Famine and drought. Also Global warming and higher increases of heat on the environment.
The answer is anaphase.
Speaking of mitosis, which is a cell division of a single cell into two identical daughter cells, it consists of 4 phases - prophase, metaphase, anaphase, and telophase and cytokinesis. Chromatids are present only in metaphase and anaphase. During metaphase, sister chromatids join together. During anaphase, sister chromatids separate from each other to the opposite sides of the cell.
Attached are two images concerning DNA.
The first image is a diagram that illustrates the base paring of DNA. First, there is the ribose-phosphate backbone that keeps the DNA together. Then the bases thymine and adenine are joined together by two hydrogen bonds. On the other hand, the bases guanine and cytosine are joined together by three hydrogen bonds.
The second image shows the helical structure of the DNA.
Answer:
Bogota esta ubicasa en un altiplank, Llama do sabana de Bogota, en la Cordillera Oriental de la Andes a una altura de 2.640 metros (8.660 pies) sobre el nivel del mar. La region extendkda se conoce Como Altiplank Cundiboyacense, que significa "altiplano de Cundinamarca y Boyaca". El rio Bogota cruza la sabana y forma el Salto del Tequendama al suroeste. Los rios afluentes forman valles done se encuentran aldeas y cuya economic se basa en la agrictura, la ganaderia y la prosuccion artesanal. La sabana limitia al este con los cerros orientals que corren de norte a sur y contienen los cerros Guadalupe y Monssrrate. El limits occidental de la ciudad esta formado por el rio Bogata. Hacia el norte, el Area Metropolitana de Bogata se extiende sobre el altiplano hasta las localidades de Cina y Sopo.

Answer:
macroevolutionary; background; mass
Explanation:
Macroevolution is defined as the evolutionary process of higher taxa (above the species level). Macroevolutionary patterns include stasis (lack of evolutionary change over a long period), speciation (diversification), lineage character change (modification of major features/traits), and extinction (termination of a species or taxon). Moreover, background extinction refers to the extinction of individual taxon/species due to environmental factors (e.g., climate change, disease, habitat loss, competition, etc), which account for the majority of all extinctions. Conversely, mass extinction refers to the time period in which a major proportion of all known species (about three-quarters or even more of all species) living at the time goes extinct.
