Thermoregulation is the process of regulating the internal body temperature of animals within a certain range. Endotherms, such as mammals and birds, thermoregulate internally by generating heat from metabolic processes and are able to keep their body temperature high and relatively constant, adapting to the environment to maintain homeostasis. This type of thermoregulation requires a high metabolic rate, that enables organisms to be more physically active without having to rely on the…

measurement of nutrient absorption by the hummingbird’s intestine and measured crop emptying times. It was determined that hummingbird intestine has the highest active glucose transport rate and the lowest passive glucose permeability reported in vertebrates (Diamond et al. 1986). 4. Wing-pitching mechanism of hovering Ruby-throated…

and the amygdala, which is responsible for conditioned learning would not be present in the telencephalon (Hines, 2016 April). However, recent studies have shown that the brain structures for fish are as equally as complex as those of “higher” vertebrate groups, with the only difference lying in the development of the telencephalon. In ray-finned fish, also known as telosts, the telencephalon is divided into “two massive hemispheres” and research has shown that divisions in the telencephalon…

to understand the complex processes involved in genetics and development. The nervous system of Drosophila and vertebrates consists of neurons and glial cells. Glial cells are the most abundant cell type in the nervous system. Glial cells are cells in the central and peripheral nervous system that provide support and protection for neurons, form myelin and provide insulation. In vertebrates, the glial cell subtypes are: astrocytes, oligodendrocytes, microglia, and Schwann cells. In Drosophila,…

into a full organism. The sea urchins both grew and lived. Scientist soon became fully aware of the whole “embryo twinning” and started doing their own evaluations on the concept. In 1902 Spemann a researcher took a challenge of twinning a vertebrate (a vertebrate is…

anal and caudal fin, a cloaca is located right behind the anal fin and this is where the cut is made until the beginning of the head. The fillet is removed to expose the internal organs. The crucian carp anatomy is similar to that of the other vertebrates. The fish contains most of the internal…

The existence of these animals differs but many of these animals lives in the warm and shallow waters. Venomous marine animals divides into vertebrates and invertebrates , It is believed that there are at least 200 species of poisonous vertebrate fish distributed throughout the world including stingrays, scorpionfish, stonefish, catfish, that differ in Both the number and severity of injury (Kizer et al., 1983)., venomous fish got the attention…

BBC News stated that approximately 700 animals are being killed to for animal testing, but out of those 700 only one animal did not die in vain. This animal found a cure for a human illness, yet the rest 699 animals died in the name of science. Before these animals died, they experienced torture, suffering, pain, and fear. These animal 's fear being next and not being able to survive. If they survive the torture, they will keep fighting until they realize the pain is part of their daily routine.…

1) What is a difference between endotherms and ectotherms? The difference between an endotherm and an ectotherm is how their body is composed for regulating body temperature. This is important, as body temperature is key to maintain homeostasis. While ectotherms must rely on outside variables to regulate body temperature endotherms can regulate body temperature using mechanism within their own body. A major adaptation in endothermic organisms that is not seen in ectotherms is the large number…

careful incisions, viewing the inside of the rat’s anatomy. The rat is a typical mammal, with a head, clearly defined neck, trunk and tail. As such, the rat has two unique aspects that distinguish mammals from other vertebrates: an external covering of hair and mammary glands. As a vertebrate mammal, much of the rat’s structural organization is common with humans. The similarity of structures among both organisms, rats and humans, is evidence of common ancestry; thus, it can be said that…
