Pls answer!!
a) Based on this information and the food chain below, what are the implications of
not taking immediate steps to reduce CO2 emissions in the atmosphere? (2 points)
algae → snails — crabs — salmon → man
b) Because killer whales are at the top of many food chains, it may seem as if they
are not at risk of starving if seals die off. Why is this not necessarily true? (2 points)
Answers
Answer:
a) Higher carbon dioxide levels means a rapid growth of Algae, especially toxic blue-green algae that can float to the surface of the water. This growing amount of Algae will expand across the ocean and clutter it. Harmful algal blooms can be harmful to aquatic life, as some produce toxins that can make animals sick, while others can die off in large quantities and deplete oxygen in the water when they decompose. Snails, specifically aqaurium snails, crabs, and salmon do feed on Algae, which could control it to a degree. However, as the ocean becomes more acidic, it could dissolve the shells of crabs and snails, which will cause them to cook in the sun, and therefore die out. As for salmon, studies showed that high CO2 concentrations disturb fish acid-balance, induce stress response, increase nephrocalcinosis incidence, energy metabolism, and feed conversion ratio, and reduces body condition factor, feed intake, and growth. Fish in this condition are very vunerable to dying despite food being all around them. Additionally, fish in those conditions are not suitable for consumption, which means less food for mankind.
b) This is not true. Although they eat sharks, whales, and dolphins, that is just occasional. Seals are their primary meal. As the killer whale is a consumer, it cannot provide food/energy for itself, therefore relying on organisms below it on the food chain. The killer whale predominately consumes seals, being it’s only large predator, killer whales are crucial to the stabilisation of seal population.

Based on your knowledge of protein synthesis and the information in the diagram,
summarize how enzymes are made. (3 points)
Answers
Explanation:
The chemical reactions involved in photosynthesis are controlled by enzymes . As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of collisions between enzymes and substrate.
Enzymes are biological catalysts - they speed up chemical reactions. The reactions of photosynthesis, and many other biological processes, are controlled by enzymes.
Enzymes are required for most of the chemical reactions that occur in organisms. These reactions occur in the breakdown of chemical molecules, which we see in the digestive system.

To understand these answers, we need to know what metallicity.
What is metallicity?In astronomy and physical cosmology, metallicity (also called Z) of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium. Because stars, which make up most of the visible matter in the universe, are composed primarily of hydrogen and helium, astronomers conveniently use the generic term "metal" to describe all other elements collectively.
With this information, we can conclude that we have recorded the elements present in each unknown astronomical object according to metallicity.
