1.The passage says that every animal is a living radiator because it ___.[ ]A. produces heat in its body cells B. burns fuel to produce heat C. sends out heat through its skin D. takes in oxygen for burning fuel 2.Small animals are said to live faster than big ones because they...
(this is always a limiting factor); that these species should not compete with humans for their own food; they must be easy to breed and inexpensive to produce; and they must be able to adapt to the climatic conditions of the countries; and they must bear the heat, through their own ...
They help birds reduce body heat. Mammals (哺乳动物), which breathe air, have backbones, grow hair and produce milk, use similar methods. They use their ears, tails and legs to help them control body temperature. Scientists have studied this in the past years. They have studied animals in...

If wild animals are experiencing terribly high temperatures, although you won't see death, you might see changes in their bodies that show they're getting close to death. By studying responses like these, scientists could get a nearly warning sign before heatwaves start to produce more serious...
death."如果野生动物正在经历可怕的高温,虽然你不会看到死亡,你可能会看到他们的身体变化,表明他们正在接近死亡。此处"By studying responses like these, scientists could get a nearly warning sign before heatwaves start to produce more serious results."句意:通过研究这些反应,科学家们可以在热浪开始产生更严重...
You are familiar with the adaptive radiation of Darwin's finches that resulted in species with different beak shapes. But did you know that this affected their songs as well? Larger-beaked species have simpler songs as their muscles simply cannot move their beaks fast enough to produce the ...
As reptiles, turtles are ectothermic, meaning that they can't produce their own body heat and instead receive heat from the environment. To save energy, turtles brumate when temperatures start dropping. Like hibernation, brumation is a period of inactivity during winter. Unlike hibernation, howe...
When expressed, the livestock animals produce a PRLR that is missing up to the terminal 148 amino acid (aa) residues of the protein all ranges and values within the explicitly stated range are contemplated: e.g., from 148 to 69. Animals expressing SLICK have superior thermoregulatory ability ...
