PLEASE SOLVE THE PROBLEMS WITH "correct" answers, instead of just writing answers. THANKS!
(1) Halophytes are plants that live in moist soils with high salt concentrations. Despite being surrounded my water, halophytes are often referred to as "salty desert" plants. Explain why they are given that name.
(2) High salt concentrations can be toxic to plants as they have the potential to disrupt essential cell funtions. Yet many halophytes sequester high amount of salt in their vacuoles, while also metablozing amino acids and carbohydrates for deposition in the cytoplasm. Explain why it would be adaptive for halophytes to accumulate salt and why releasing organic compounds in the cytoplasm is necessary for proper water balance in the cells.
(3) You are interested in plant life history evolution, You come across a population of the California poppy that i spolymorphic (mixed) for both iteroparous ans semeparous individuals. You would like to use established models from life history theory to design experiments to provide you with the necessary data so you can predict whether semelparity or iteroparity will come to dominate that population in the future (assuming the environment rematins constant). Using what you know about the demographic theory, what are the factors that you would need to measure to be able to make such a prediction.
In which parts of a plant where photosynthesis takes place?
Choose a species and describe some adaptations that species developed that allow them to survive in their native habitat
Identify and describe the three types of nuclear waste. What are the problems associated with the disposal of these wastes? Your response should be at least 150 words in length.
A heterozygous, but phenotypically wild-type fruit fly (gray body color and normal wings) was mated to a black fly with vestigial wings. The offspring had the following phenotypic distribution: wild type, 720; black-vestigial, 780; black-normal, 280;..
In a hemoglobin variant known as hemoglobin Kansas, an Asparaginein the beta chain is replaced by a Threonine. This results in thedisruption of a hydrogen bond that normally stabilizes the R-stateof hemoglobin.
In drosophila the gene (vg) for vestigial wing is a recessivelocated at 67.0 units from the left end of the second chromosome.The gene (cn) for cinnabar eyes is also recessive and is located at57.0 units from the left end of the chromosome.
Do cofilin and profilin increase or decrease the critical concentration of acting polymerization?
Examination of a wright stained smear revealed many smudge cells with very few intact leukocytes. What is the appropriate corrective action to minimize the number of smucge cells?
Which factor does not greatly influence the rate of sugar transport in the phloem?
One of Mendel's classic experiments involved crossing yellow (dominant) and green (recessive) truebreeding strains of peas. Using Punnett squares and starting with the parental generation, explain in which cases Mendel saw a 3:1 ratio of yellow:gr..
