1) Monocots are shorts for “Monocotyledons” which means plants whose embryo has one cotyledon; whereas, Eudicots (Eudicotyledons) carry embryo with 2 cotyledons. The cotyledons of eudicots supply nutrients for seedlings, but the cotyledons of monocots store some nutrients and act as a transfer tissue for nutrients stored elsewhere. Five key features are typically used to distinguish monocots from eudicots; a seed, arrangement of vascular tissue in roots, stems, and leaves, and number of flower parts. The seed has the reproductive structures that are protected from drying out, have male and female gametophytes which are reduced in size. In young dicot stems and stems (usually the upright, vertical portion of a plant transports substances to and the leaves) that do not increase in thickness, xylem and phloem are arranged in vascular bundles in the cortex.
Onion, Cheek, and Elodea cells are all eukaryotic. Onion and Elodea cells are plant cells. Cheek cells are animal cells. They all have nuclei and cell membranes. 2.
The resulting organism was found to be Staphylococcus auricularis. Staphylococcus auricularis was identified as a new species in 1983 by Wesely E. Kloos and Karl h. Schleifer. (Kloos, 1983) Kloos and Schleifer Identified 20 different strains Staphylococcus auricularis from 16 different people. (Kloos, 1983) Staphylococcus auricularis is a normal floral inhabitant of the human external ear. Staphylococcus auricularis were first distinguished from other Staphylococcus by growth rate and colony morphology on agar, carbohydrate reaction pattern, cell wall composition, and deoxyribonucleic acid sequence.
Approximately _____15,00_____ acres of fresh tomatoes and ____110,000______ acres of processing tomatoes are grown annually in the southern San Joaquin Valley. True or (False) (italicize one): California is NOT the major supplier of carrots for the US. http://pubs.usgs.gov/circ/circ1182/pdf/06SanJoaquinValley.pdf Mining ground water for agriculture has enabled the San Joaquin Valley of California to become one of the world’s most productive agricultural regions, while simultaneously contributing to what? ____to one of the single largest alterations of the land surface attributed to humankind.___ California ranks as the largest agricultural producing state in the nation, producing what percent of the total U.S. agricultural value? ____11_____% The Central Valley of California produces about what percent of the nation’s table food on only 1 percentof the country’s farmland?
Humans can survive in any area that provides food, water and clean air. The biosphere must maintain a stable atmosphere and climate as well as protect humans from solar radiation. Based on this week’s required readings, what are the main causes of threats to the biosphere? Global warming Water shortage Loss of usable land Pollution Over population Social ills Pandemics Melting of polar ice caps Rising sea levels Extinction of species Define sustainability. According to Dictionary.com the definition for sustainability is as follows: the ability to be sustained, supported, upheld, or confirmed.
It can live and grown with or without oxygen. B. Discuss the temperature requirements of the organisms in this lab. The temperature requirement for this lab was 37 degrees Celsius , it was very important to keep the temp at this level for the bacteria(S. epidermidis and L. acidophilus) to grow. According to the Labpaq 37degrees Celsius is considered “average” temperature to grow bacteria (Mesophiles).
The diploid state in plants is known as sporophyte which produces spores and the haploid state in plants is known as gametophyte which produces gametes. Unlike woman who always produce an egg and men who always produce sperm some plants have different dominate diploid stage than haploid stages. Some examples of plants with dominate haploid stages are green algae, mosses, liverworts and hornworts. Some examples of plants with dominate diploid stages are wiskferns, horsetails, and true ferns. ten ways in which plants in general or specific plants provide for you in your life and HOW they benefit or enrich your life 1.
Biology Gynoecium: - The gynoecium (from Ancient Greek γυνή, gyne, meaning woman, and οἶκος, oikos, meaning house) is a term with several meanings in botanical usage. In reference to mosses, liverworts and hornworts,gynoecium refers to a cluster of archegonia and any associated modified leaves or stems present on agametophyte shoot. More commonly, gynoecium refers to the ovule-producing part of a flower. The gynoecium is typically the innermost whorl of structures in a flower and is surrounded (in perfect flowers) by the androecium (stamens) and (in complete flowers) by the perianth (petals and sepals). The gynoecium is often inaccurately [clarification needed] referred to as female because it gives rise to female (egg-producing) gametophytes.
ii Going back to Vulpes zerda specifically, these desert dwellers are able to keep their internal desired temperature regardless of the fluctuation of the environmental heat through their endothermic characteristics. For this animal and other endotherms alike they are able to cool their bodies with rising temperatures and warm their bodies with low temperatures versus ectotherms that rely mainly on behavioral strategies to battle environmental changes. These carnivores are also described to be homeotherms which are animals that are capable of keeping a relatively constant temperature within their bodies. Insulation is a key component in thermoregulation of these homeotherms in which they are able to minimize the interaction of the environmental heat with their bodies. Burrowing is a common behavioral response of insolation in protecting themselves from the intensity of the heat and sun of the desert.
This happens when new organisms colonize an area that has already hosted life as a result of primary succession. One example of secondary succession is evident in the far reaches of the foredune community with the Cottonwood tree. These trees have triangle shaped leaves and can grow up to eighty feet high. Their stems act like roots when buried under the sand, allowing them to thrive in the semi-compacted sand as they grow taller by helping to anchor the tree. In this way, the Cottonwood acts as a precursor in succession for larger trees along with Marram grass due to its role in helping to stabilize the soil.
