The effect of caffeine on the heart rate of Daphnia pulex Introduction In this experiment the effect of caffeine on the heart rate of Daphnia will be tested by use of a microscope and caffeine solution. Daphnia pulex is a crustaceous animal found in the ocean. There internal organs can be visible to observe because their body is translucent. This would be interesting because we could see how the effect of caffeine effects the heart rate of humans as well. Carrie miller from university of…

This is a major problem because, people around the lake will slowly start getting sick and one day the all the fish and plants in this water will die…

The Pacific leaping blenny effectively established its population on land through an evolved variety of adaptations, such as: the ability to move efficiently on land and being able to perform respiration through its skin while still relying on its gills. The fish are limited to the “splash zones” of…

In Florida panthers are endangered. There is about 100 wild Florida panthers. These panthers are not being killed due to natural causes, it’s due to humans destroying their habitats and our killing.

Panthers help us in many ways! Panthers regulate our food chain. If they didn’t regulate our food chain, it would unbalance the…

Fierce Fish The ocean is like a crowded city full of people. Everyone is walking around going to their destinations. An ecosystem is all living things (plants and animals) and nonliving things that live in a specific area. The man-of-war jellyfish lives in the busiest area of all, the neritic zone. The neritic zone is packed of ocean animals because it gets the perfect portion of sunlight, it’s a good temperature, and not lots of pressure. The neritic zone is located on the continental shelf.…

unrealistic and dreamlike. I’m so used to murky or exceptionally cloudy water, shocking me even more by how beautiful it was. My family had the luxury of basically doing whatever we wanted to in the ocean. This was reinforced by the second largest coral reef in the world, the Grand Mayan Reef.

I was too young to go scuba diving, but even if I was of…

The deepest part of the ocean is called the Challenger Deep and is located beneath the western pacific ocean, which runs several hundred kilometers. The ocean is home to more than a million different types of species, with half of them on the verge of being extinct. Being home to various types of creatures, there must also be a vast amount of space for them to inhabit. Ocean travel by boat dates back millions of years, but…
