Living organisms in any biome interact through a variety of relationships. Organisms compete for food, water, and other resources. Predators hunt their prey. Some organisms coexist in mutually beneficial relationships (symbiosis), while others harm organisms for their own benefit (parasitism). Still others benefit from a relationship that neither helps nor harms the other organism (commensalism).
Animals found in the Arctic tundra include herbivorous mammals (lemmings, voles, caribou, arctic hares, and squirrels), carnivorous mammals (arctic foxes, wolves, and polar bears), fish (cod, flatfish, salmon, and trout), insects (mosquitoes, flies, moths, grasshoppers, and blackflies), and birds (ravens, snow buntings, falcons, loons, sandpipers, terns, and gulls). Reptiles and amphibians are absent because of the extremely cold temperatures. While many of the mammals have adaptations that enable them to survive the long cold winters and to breed and raise young quickly during the short summers, most birds and some mammals migrate south during the winter
Three roles of the DNA molecule in heritage are in storage, copying and transmitting genes.
A-DNA: It is a right-handed double helix similar to the B-DNA form. ...
B-DNA: This is the most common DNA conformation and is a right-handed helix. ...
Z-DNA: Z-DNA is a left-handed DNA where the double helix winds to the left in a zig-zag pattern.
Answer:
<em><u>The correct option is D) The two species have a common ancestor</u></em>
Explanation:
In evolutionary studies, homologous structures can be described as structures which are similar in organisms of different species because they had a common ancestor in the past. These structures may not perform the same function but are similar because they arose from a common ancestor. Hence, the bone in a bird's wing can be homologous to a bone in a lizard leg because they have a common ancestor in the past.
Answer:
Corrigiendo el error de Schwann y preparando el principio de Virchow, señaló que las células se multiplican por escisión de su núcleo, no por generatio aequivoca a partir del protoplasma originario. ... Según los historiadores Pagel (1945) y Ackerknecht (1957), parece que Remak precedió a Virchow en sus descubrimientos.
