Summary Introduction
To write:
The prediction of whether all mammals produce the active form of vitamin D by the use of sunlight.
Introduction:
Vitamin D is a vitamin that is found in the liver and fish oils. It is important for the absorption of calcium. It prevents rickets in children and osteomalacia in adults. It includes vitamin D2 (calciferol) and vitamin D3 (cholecalciferol).

Chapter 3 discussed the importance of increasing your walking pace to achieve optimal health benefits. The chapter even discussed how walking at such increased speeds could help you burn calories like a runner. Was this information surprising to you? That is, were you surprised to learn that by just increasing your pace, you could burn the same amount of calories as someone running as their physical activity?
Small mammalian hibernators can withstand body temperatures of 0° C to 5°C without injury. However, the body fats of most mammals have melting temperatures of approximately 25° C. Predict how the composition of the body fat of hibernators might differ from that of their nonhibernating cousins.
Which of the following statements correctly describes a difference between plants and animals?
(a) only animals need to take in water to survive
(b) plants do not have ways of defending themselves, but most animals do
(c) animals have internal structures that help them break down and absorb nutrients
(d) plants have structures that allow them to make their own food

- Photosynthetic sun-basking shark: They grow to about 4 m long, are grey or brown bodied, with all of their fins being green. Their green fins have chlorophyll, so that they can convert sunlight to energy. Has a very tall dorsal fin and long upper caudal fin because of it. They still have gills but have developed the ability to close their gills so that they can “bask” on the surface of the water for up to 10 minutes without suffocating. They still consume small fish for nutrients as well. Decide what Kingdom and Phylum these organisms would fall under and explain your reasoning. If you feel that a new Kingdom and/or Phylum needs to be created for this organism, explain why, and list basic characteristics of your new Kingdom and/or Phylum.arrow_forwardWhich of the following help mammals retain body heat? hair and body fat Obones and body fat bones and sweat glands hair and sweat glandsarrow_forwardHow does cellular respiration differ in prokaryotes and eukaryotes?

- Bats mostly hunt insects at night. They are able to determine the distance and speed of any prey they are chasing, which has helped them to become excellent nocturnal predators. One potential prey, the tiger moth, has developed two separate methods of evading predation. First, tiger moths emit a toxin that is distasteful to bats, birds, and most other vertebrate predators. Second, they use an organ called a "tymbal" to create a series of high-pitched clicks that only bats can hear, and which identify the tiger moths as something the bats don't like to eat. Bats who prey on tiger moths discover they don't taste very good, learn to identify tiger moths by their clicks, and avoid eating them. Use this information to answer the questions below. Question 1: The scenario above describes a distinct evolutionary interaction. What is it?Can you explain? Question 2: Why is it necessary for the moth to produce both a tymbal click and a toxin? Why not just a toxin?
