Lab report 3 At first glance it may appears unbelievable, because human bipedalism is such a key evolutionary innovation. Few characteristics of being human have engrossed such intense debate than the fact that, distinct from many other living mammals, humans walk upright on two legs. Unlike the quadrupedal primates, bipedal primates are sluggish, clumsy, and particularly unbalanced and disposed to to falls and injury. In spite of the negatives characteristics, bipedalism has allowed humans to…

climate, predators, or competition for food. These organisms tend to survive and reproduce in greater numbers than the other fraction of their species. This guarantees that the prolongation of those favorable traits is continued to subsequent generations. Charles Darwin believed that organisms survived through the process of natural selection. Some species of animals and plants can effectively adapt by meeting the requirements of their natural habitat.…

How to grow Sarracenia Pitcher plant from seed. In order to grow a Sarracenia pitcher plant from seed, you need to have time, and patience. Sarracenia has to be watered with rain or purified water every day or every other day. Never allow the soil to get dry, but you also never want your plant to sit in water. Too much water can make a plant mold causing it to die, or be very difficult to take care of. Sarracenia is a carnivorous plant. Therefore it likes soil with little to no nutrients. The…

The calendars mark 2100. Another year closer to the end. Outside the temperature is 113℃, the usual for July in Dallas. In the news, reports about the decrease in freshwater availability has become the norm. Various animals have gone extinct, plants are unable to thrive in any country because of extreme droughts, and the population has began to decline steadily all over the world. A few scientists shared their ideas on how to keep humanity from vanishing. But many know that the end of the Earth…

conservation aims to take off the blindfold on modern society and open their eyes to the way they abuse the things that single handed us give us life. Our buildings, transportation systems, energy use, and production methods all affect the many animal species and ecosystems that provide us with necessities from the natural world. Without genuine concern for animal welfare/extinction, we are jeopardizing environmental growth for ecosystems, potentially destroying food chains that could make…

One of the five agents of microevolution is natural selection. It influences changes in gene frequencies in a population. Natural selection is defined as a process in which there is a competition to pass on genes. In natural selection, some traits are more favoured than other traits. This may result in changes in a population. The favoured traits become more common compared to the traits that are not favoured. The favoured traits are based upon on the environmental conditions. When certain…

mammal species were identified from all study sites (full list in Appendix 1). Swamp Wallaby, Bush rat, and Long-nosed Potoroo triggered most of the images containing terrestrial mammals. Swamp Wallaby, Short-beaked Echidna, Bush Rat and Eastern Grey Kangaroo were widespread over the study area. With the exception of Dusky Antechinus and Long-nosed Bandicoot, detection probabilities were high (0.80 – 0.99) (see Appendix 1 for details). The FD index calculations required at least three species…

water, enough oxygen for the masses, and with a viral pandemic plaguing humanity, it is not a farfetched vision. In our world today, “the walking dead” are not zombies on a mission to terrorize humans; the walking dead are millions of plants species, animal species, and ecosystems that are quite literally:…

of a community of species on the rocky shore of Te Raekaihou Point. The site data was collected from the rocky shore at Te Raekaihou Point, and my chosen species are the Blue-Banded-Periwinkle (Austrolittorina antipodum), and the Brown-Barnacles (Chamaesipho brunnea). The community pattern found in the rocky shore is zonation. Zonation is the division of plants and animals into distinct horizontal bands, or ‘zones’. The data collected shows zonation of the plant and animal species’, where the…

Describe how you would perform a random sampling to estimate the size of the population of your species you chose in the Galapagos. Use some actual numbers in your description. Try to base it on real numbers (this may take some research). What underlying assumptions must be made for this technique to be effective? [ /6 marks] Random sampling is a method used by biologists to estimate the size of a population by collecting data as each organism usually can’t be accounted for separately. By using…
