<span>Down syndrome
is a chromosomal condition that is associated with intellectual
disability, a characteristic facial appearance, and weak muscle tone
(hypotonia) in infancy. All affected individuals experience cognitive
delays, but the intellectual disability is usually mild to moderate.</span>
Answer:
Animal Respiration Every cell in an animal requires oxygen to perform cellular respiration. Cellular respiration is the process by which animals take in oxygen and exchange it for carbon dioxide and water as waste products.
<span>The answer to your question is that all of the energy is ultimately radiated into empty outer space as heat. The second law of thermodynamics mandates that all processes that involve the transfer of energy MUST radiate a portion of this energy into space as waste heat. This is why when you run down the street you get hot and sweaty, and this is why automobiles MUST have a functioning radiator and nuclear power stations MUST have evaporation cooling towers or else be located near a large body of water to exchange excess waste heat into, etc., etc. It is also true that the transfer of energy at each step up the food chain is very inefficient. They say it takes around 50 lbs of corn to produce one pound of beef, and it probably takes 20-30 pounds of beef to produce one pound of human tissue. The rest of the energy just goes into your living room as radiated body heat. I hope this helps.</span>
Answer:
external fertilization
Explanation:
External fertilization cannot happen on land since it needs a medium for the fertilization to be able to take place, but land cannot provide the medium.

What animals did the grant study in galapagos island?
Galapagos finches did the grant study in Galapagos island.
Galapagos finches is a piece of evidence supporting the theory of evolution.
Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.
What did he observe?
During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galapagos. He had learned how to preserve bird specimen while at the University of Edinbugh and and had been keen on shooting, but he had no expert in ornithology and by this stage of the voyage concentrated mainly on geology. Nonetheless, these birds were to play an important part in the inception of Darwin’s theory of evolution by natural selection.
What was the brief goal of their studies?
All of Darwin's observations and insights, plus reading of increasing population growth and demand for limited resources, brought him to his theory of natural selection. Briefly, this means that individuals better adapted to their environment survive and increase in number through reproduction.
What did they conclude?
Conclusion:
Charles Darwin deserves primary credit for the theory of evolution. He developed existing ideas about descent with modification while providing a large body of evidence in support of them, and he was the first person to perceive thatnatural selection is the primary force behind evolution.
