1) What are two practical actions that can be done/implemented to prevent and/or improve environmental justice? 2) Name 3 characteristics that make communities vulnerable to environmental injustice. How does that make you feel that these characteristics increase the risks of a person’s exposure to environmental pollution? 3) What commonalities and differences do you see between […]
Explain how neurons communicate using action potentials and neurotransmitters. the answer must compare and contrast the similarities and differences between these two means of communication BACKGROUND SUBJECT: Under resting conditions, the concentration of sodium ions — shown here in red — is about 10 times higher outside the neuron compared to the concentration inside. At […]
Discussion Prompts: Technology has given rise to many new opportunities for health care and treatment for patients. These advances in science have extended lives and increased the quality of life for many people. Research a new technology involving genetics or healthcare advancements. below are some examples for inspiration: somatic cell nuclear transfer, Invitro fertilization/embryo freezing, […]
How would you summarise an investigative report on LSD effects on rat brains – I have got most of the information and have tried to find examples of what to include but my report reads more essay-like. Any advice on setting it up, pointers on info, and what should be included would be helpful, also […]
Predict the number of DNA fragments and their sizes if Lambda phage DNA were incubated and cleaved simultaneously with both Hind III and Eco RI (refer to the map below).
The DNA code is read in groups of three nucleotides called codons. Explain why reading the code in pairs of nucleotides is not sufficient. [K/3marks] 3. How does the fact that DNA Replicates semi conservatively decrease the possibility of errors made during DNA replication? [A/3marks] Unit 4 – Homeostasis I Define and give an example […]
What types of gene or protein families may be important for multicellularity? Can we compare the genomes of different multicellular lineages like animals and plants to identify the most important genes critical for multicellularity? Why or why not? 10) As we have discussed in the lecture, homeotic genes specify the segmental identity and all encode […]
Describe the course of human evolution from that of the early vertebrates to the emergence of humankind. Discuss the impact that both natural selection and fitness have had on each step of this evolutionary journey
Which of the following statements about atmospheric gases is correct? The atmosphere consists mainly of oxygen, followed by nitrogen and carbon dioxide. B Plants use nitrogen and carbon dioxide to make food and give off oxygen. C Animals use oxygen and small amounts of nitrogen and give off carbon dioxide. D Plants and animals use […]
Please help me with this question with your own work! Imagine that you collected individuals of a species of hydra and established six replicate populations in your lab at home. In the wild, this species carries a few bacterial parasites, but shortly after creating your six populations, you treat each with antibiotics and eliminate all […]
