Answer:
A biologist studying ponds in Alaska wants to determine if the temperature of a pond affects the length of the fish in that pond. He traps and measures fish in each pond, gathering the following data:
Choose a way to represent this data using either a bar graph or a scatter plot. Then write a summary of the data to answer the question as to whether temperature is related to the size of fish.
Explanation:
Transpiration in plants requires adhesion of water molecules to cellulose, cohesion between water molecules, evaporation of water molecules and transport through tracheids. Cohesion between water molecules is as a result of hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule. Transpiration involves the release of water through the leaves in pores called stomata, this serves as a method of excretion of excess water and diffused gases.
Answer:
Due to the presence of limited number of species.
Explanation:
Bear island provide a great opportunity to decipher entire food chains because this island has many animals species which interact with each other or depend on one another due to the presence of less animals for feeding purpose. This island is isolated from the rest of the world so it provide a great opportunity to study the entire food chains that are present at that island. There is less number of species so knowing about their feeding choices is easier for the ecologists.
Answer:
Cyanide may cause muscle weakness because tissues are not able to use oxygen for cellular respiration
Explanation:
Cyanide is a highly toxic compound that inhibits cellular respiration by inactivating cytochrome oxidase in mitochondria, which is a key enzyme responsible for oxidative metabolism and energy production. Thus, cyanide consumption decreases the utilization of oxygen by muscle cells, thereby causing weakness. The symptoms of cyanide poisoning include, among others, weakness, malaise, visual disturbances, muscle pains, etc.
