Fast swimming marine predators such as dolphins, sharks, and tuna, have a ______ body shape that minimizes _______ in the water.

Answers

Answer 1
Fast swimming marine predators such as dolphins, sharks, and tuna, have a streamlined body shape that minimizes drag in the water. This body shape, also known as fusiform, is elongated and tapered at both ends, with a pointed head and a streamlined tail. This design reduces the amount of drag that the animal experiences as it moves through the water, allowing it to swim faster and more efficiently. Additionally, these animals have other adaptations, such as a smooth skin, a layer of mucus, and specialized muscles, that further reduce drag and enhance their swimming ability.

Answers

The record of the potential differences generated by the heart and conducted via body fluids to the surface, where it is detected by electrodes, is called an: electrocardiogram (ECG) recording.

An electrocardiogram is a recording of the electrical activity of the heart. Electrodes are placed on the skin to detect the electrical impulses generated by the heart and transmit them to a machine, which records the data as a graph.

The ECG is a useful tool for diagnosing various heart conditions, such as arrhythmias, conduction abnormalities, and ischemia, and is often performed as a part of routine medical checkups, during cardiac procedures, or in emergency situations.

The recorded data can provide valuable information about the heart's structure and function, helping healthcare providers to identify and manage heart-related issues.

Groups of living things called species can interbreed to create fertile offspring and have similar traits.

Biology is based on the idea of species, which is used to categorize and comprehend the diversity of life on Earth. Millions of species have been identified, ranging from simple single-celled organisms to sophisticated multicellular organisms like humans.

They regulate populations, provide food and nutrients for other creatures, and contribute to ecosystem services like pollination and nutrient cycling, among other vital ecological tasks.

Over millions of years, species have changed due to factors like natural selection, genetic drift, and gene flow. Threats to numerous species today include habitat loss, climate change, pollution, and overexploitation by humans.
