The giraffe, the diamond python and the Tasmanian devil are all part of the kingdom of Animals. All animals have to reproduce to make their species survive. Although they have different ways of reproducing the main point of having offspring. All animals do this to exist. The animals of this report are the Diamond Python (Morelia Spilota) , Giraffe (Giraffa Camelopardalis) and Tasmanian Devil (Sarcophilus harrisii). The gestation period is the time spent in the womb from conception to birth. Giraffes and Tasmanian devils both are mammals and have gestation but snakes lay eggs where the baby is developed. The Tasmanian devil and giraffe are both mammal which means they give birth to live young and suckle their infants. Diamond pythons lay eggs so they do not develop in the womb instead the egg is developed in the mother then laid, then the foetus is made in the egg.
The diamond python is a reptilian snake. It is native to Australia living in forest and urban areas. It is a subspecies of carpet python which is very similar in weight and size but have different patterns. The diamond python has diamond pattern, black with white-cream diamonds. The average adult size is 2m and their weight is 2-5 kg They prey on small mammals, birds and small reptiles. The diamond python wraps itself around the prey and asphyxiates the animals, then it swallows it whole.
The diamond python is an oviparous animal which means that it lays eggs and the embryo has no development inside the mother. When snakes mate the male has a hemipenes that fertilise the ova inside the mother snake. Then once the ova has been fertilised eggs start to develop and they come out of the cloaca which is the common cavity where it excretes and mates. The python then coils a...

The descendants of the first radiation of mammals, monotremes have characteristics of both placentals and marsupials, while still retaining characteristics of reptiles and birds in a combination all their own. Introduction At first glance, platypuses seem to be an amalgamation of mammals, birds, and everything in between. In fact, their reproduction biology also has much in common with a variety of animals—reptiles, birds, placentals and marsupial mammals. Platypuses belong to a group of animals called monotremes. These egg-laying mammals have been a mystery to researchers since their discovery by Westerners over 200 years ago.
Giraffes are placed in the family, Giraffidae, separate from other animals such as the camel, deer, and cow. Typically, giraffes are about 19 feet tall and can weigh as much as 4000 pounds. The evolution of modern giraffes began about 1 million years ago from a similar species known as Giraffa jumae. Those species were known for their massive skeletons and antler-like structures, not found on giraffes of today (Simmons 772). Today, there are nine widely excepted subspecies of the giraffes which are differentiated by the spots on the trunks and their geographic region.

Biology literally means "the study of life". Biology is such a broad field, covering the minute workings of chemical machines inside our cells, to broad scale concepts of ecosystems and global climate change. Biologists study intimate details of the human brain, the composition of our genes, and even the functioning of our reproductive system. Biologists recently all but completed the deciphering of the human genome, the sequence of deoxyribonucleic acid (DNA) bases that may determine much of our innate capabilities and predispositions to certain forms of behavior and illnesses. DNA sequences have played major roles in criminal cases (O.J. Simpson, as well as the reversal of death penalties for many wrongfully convicted individuals), as well as the impeachment of President Clinton (the stain at least did not lie). We are bombarded with headlines about possible health risks from favorite foods (Chinese, Mexican, hamburgers, etc.) as well as the potential benefits of eating other foods such as cooked tomatoes. Informercials tout the benefits of metabolism-adjusting drugs for weight loss. Many Americans are turning to herbal remedies to ease arthritis pain, improve memory, as well as improve our moods. Can a biology book give you the answers to these questions? No, but it will enable you learn how to sift through the biases of investigators, the press, and others in a quest to critically evaluate the question. To be honest, five years after you are through with this class it is doubtful you would remember all the details of meatbolism. However, you will know where to look and maybe a little about the process of science that will allow you to make an informed decision. Will you be a scientist? Yes, in a way. You may not be formally trained as a science major, but you can think critically, solve problems, and have some idea about what science can and cannoit do. I hope you will be able to tell the shoe from the shinola.
16. Describe two evolutionary consequences if the process of crossing over in meiosis ceased to occur. If crossing over in meiosis ceased to occur there would be less genetic variations and no diversity among a species. This would essentially mean that a species would not be able to adapt to an issue that could arise in the future, meaning that its species could potentially become extinct due to climate change or other arising events.
This paper is all about how giraffes can do amazing things. Such as what they eat and why people hunt them. This paper is also about their characteristics. To find out more about giraffes keep reading this amazing paper. I
Natural selection is a process of evolution this occurs due to both biotic. Natural selection is the survival and reproduction of individuals with different phenotypes. In some cases natural selection can be directly observed, Data from the Earth Watch Institute show birds beaks from the Galapagos Islands being naturally selected for throughout different environmental changes such as, after droughts occur and the islands are dry the bird population has stronger beaks which allows them to eat tougher seeds .
Reptiles are vertebrate, or backboned animals constituting the class Reptilia and are characterized by a combination of features, none of which alone could separate all reptiles from all other animals.The characteristics of reptiles are numerous, therefore can not be explained in great detail in this report. In no special order, the characteristics of reptiles are: cold-bloodedness; the presence of lungs; direct development, without larval forms as in amphibians; a dry skin with scales but not feathers or hair; an amniote egg; internal fertilization; a three or four-chambered heart; two aortic arches (blood vessels) carrying blood from the heart to the body, unlike mammals and birds that only have one; a metanephric kidney; twelve pairs of cranial nerves; and skeletal features such as limbs with usually five clawed fingers or toes, at least two spinal bones associated with the pelvis, a single ball-and-socket connection at the head-neck joint instead of two, as in advanced amphibians and mammals, and an incomplete or complete partition along the roof of the mouth, separating the food and air passageways so that breathing can continue while food is being chewed. These and other traditional defining characteristics of reptiles have been subjected to considerable modification in recent times. The extinct flying reptiles, called pterosaurs or pterodactyls, are now thought to have been warm-blooded and covered with hair. Also, the dinosaurs are also now considered by many authorities to have been warm-blooded. The earliest known bird, archaeopteryx, is now regarded by many to have been a small dinosaur, despite its covering of feathers The extinct ancestors of the mammals, the therapsids, or mammallike reptiles, are also believed to have been warm-blooded and haired.

A crocodile appears as a fierce predator and its appearance is no lie. Crocodiles are violent carnivores and there physical traits help it be successful in its hunting. They are aquatic creatures built for the predator lifestyle. There bodies are designed to swim quickly as they are able to tuck in there feet and cut through the water with little resistance. There feet are also webbed and although are not used to gain speed they are used to make quick changes in directions or sudden moves. There feet are also an advantage in shallow water where they will typically walk. They also have a thick layer of tissue around the mouth that prevents water from entering while they dive down. Crocodiles unlike many reptiles lack a certain characteristic that most have, they do not have the ability to stick out their tongue. This is caused by the membrane that holds there tongue in place giving it little movement. The skin under there bellies and sides is smooth and fragile unlike the rest of their body. On the dorsal side the skin is very thick and rugged and in some parts rather sharp, this gives them a layer of protection. There are pores and capillaries in between the scales that provide feeling and gives them the ability to know hot from cold. Crocodiles produc...
The Giraffe is one of the most interesting creatures on earth, it is the tallest land animal on the planet and it has the tallest neck among all creatures. It is originated in Africa and it inhabits the savannahs, grass lands and woodlands. Although it has thin legs, it has a very strong kick that can lead to fatal injuries to any animal that tries to prey on it, especially lions which are more likely to target giraffes than any other animals. The giraffe would fight with other giraffes using its neck rather than its legs because legs can be fatal and dominance in the giraffe family is only shown by using the neck. The giraffe’s appearances are similar to camels in terms of features such as hooves, tall legs and long tongues, and its body movements are also similar because both animals have 4 long legs.
Both sexes have two or four short, blunt, skin-covered horns. The coat has chestnut brown blotches against a brown background, markings that blend with the many different trees. As a giraffe ages, its color grows a darker brown. Each animal has a unique set of markings. Giraffes have keen sense of smell, seeing, and fantastic eyesight. A giraffe’s lifespan is up to twenty-six years in the wild and thirty-six years in captivity. Giraffes live on dry savannas and open woodland. They range south in the Sahara and in large numbers only in East Africa. Giraffes are herbivores, they eat mainly on leaves from acacia, mimosa, and wild apricot trees.
