Science Questions And Answers

      The general characteristics of the plants in these bodies of water have strong and steady roots, or roots that are bendable, depending on how fast the current of the water is. These traits help the plants mainly so they do not get swept away. Plants that

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

Biomes are appropriate conditions for organizing the natural world because the organisms that live in them common constellations of adaptations, particularly the climate of each of the areas and the characteristic vegetation types that develops in these divisions. It should be understood that the climate is perhaps the most important in determining classes of individuals who may live in an area and the ways they should be amended to live under different conditions of temperature and precipitation and seasonal distribution of these factors element. Every place on Earth has its own climate, influenced by both macroclimate regions as the particular microclimate. The soils are very important because they are essential to determine the types of plants that will grow into a bioclimatic zone in partical, in addition, also as substrates for animals serve. In turn, the soils are heavily influenced by regional climate, as well as the geology of the bedrock. At the same time we have to keep in mind the diversity of plants like the flora just like the diversity of the fauna as well as the adaptation of both.

11. Which of the following is the best answer to why plants on land are green

The first organism you discover possesses a nucleus and seems to be engulfing another organism. Describe and defend two possible Linnaean classifications and two group classifications for this organism. (5 pts)

Roots:Extensive root system competes effectively for limited soil moisture. The root system has both deep vertical roots and shallow horizontal laterals.

One type of succession that can form an ecosystem is a lithosere. A lithosere is a plant succession that begins life on a newly exposed rock surface, such as one left bare as a result of glacial retreat, tectonic uplift as in the formation of a raised beach, or volcanic eruption. The lithosere succession is initiated by pioneer plants, such as blue and green algae with colonise the sock as there are into a lot of nutrients available and they have no root systems, so they can survive in the hostile conditions. The succession then progresses due to the pioneer plants dissolving the rock, resulting in a release of nutrients. This then means that mosses, lichens and liverworts are able to thrive on that ground as the moss can absorb nutrients from rain water and they provide their own energy from photosynthesis. These plants chemically decay the rock by releasing acids, and physically decay the rock as a result of their root systems, leading

Food provides the energy in the form of calories as well as the materials needed to build and maintain all body cells.

In Figure 1, the difference of the pH levels and the near-native soil sample and near-invasive soil sample can be seen. The pH level of the soil near the invasive Crystalline Iceplant is higher compared to that of the soil near the native Sage plant displaying a difference of almost 1 pH level (See figure for comparison). The soil near the native Sage plant possesses an almost neutral soil quality (pH is 6.975) while the

What types of organisms are found in soil? Determine the relationship between soil and organisms.

Loose soil from digging animals is easier for plants to grow in compared to the hard compacted soil found where there are no digging animals

The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.

After taking the Science Knowledge Quiz, I scored higher then I expected. Out of twelve question I got five. I expected to score a zero, maybe a one if I was lucky. But i guessed on the ones I knew nothing about. For example I had absolutely know idea who invented the polio vaccine. But with the process of elimination, it came down to Jonas Salk and Marie Curie. It came down to a 50/50 chance. Even though the last science I took was Geology, you would think I would know the difference between Astronomy and Astrology. But which one is the study of the stars. From years of listening to science teachers, I thought astrology was a made up word. When it comes to science I completely blank on the subject and don't remember anything! But one question

Erosion removes the surface soils, containing most of the organic matter, plant nutrients, and fine soil particles, which help to retain water and nutrients in the root zone where they are available to plants. Thus it affects the productivity of plants. The remaining, the subsoil, tends to be less fertile, less absorbent and less able to retain pesticides, fertilizers, and other plant nutrients. There are over 17,000 soil types recognized worldwide. They vary widely in structure, erodibility, fertility, and ability to produce crops. A generalized soil profile for a humid, temperate climate is showed. When the natural vegetation is cleared for agriculture, soils become exposed to erosion and loss of soil fertility. The removal of the above-ground natural

Significantly, desertification also cause soil erosion, which means soil surface is worn by wind and water. Desertification makes soil easy to erode by water or wind, as soil is exposed and soil structure is instable without forest. LaI R(2003) says that ““Land area globally affected by erosion is 1094 million ha (Mha) by water erosion, of which 751 Mha is severely affected, and 549 Mha by wind erosion, of which 296 Mha is severely affected.” To control soil erosion, an obvious way is virescence, enlarging forest cover, which can protect the soil far from exposing to strong wind. Also, the roots of plants under ground play a role as a framework, as they are obstructions to soil movement,
