What is deuterostome development?
Deuterostome development is a type of animal embryonic development in which the blastopore becomes the anus during gastrulation. This process is characterized by radial cleavage, indeterminate cleavage, and formation of an anus before a mouth. Deuterostomes include organisms such as vertebrates, echinoderms, and some invertebrate chordates.
Dian Fossey - born 16 January 1932, died 26 December 26 1985 - was an American zoologist who spent 18 years studying gorillas in the mountain forests of Rwanda.
And then she got killed in the bush by crazy poachers (Cannibals)
What receives blood from sinus venosus?
Sinus venosus is formed by the union of 2 post caval veins and 1 precaval vein. The sinus venosus receives deoxygenated blood and passes it into auricle in case of fishes and into right auricle in case of amphibians and reptiles.
What era are mammoths and mastadons abundant in?
Mammoths and mastodons were abundant 10,000 years ago. Currently, we live in the Cenozoic era, which began 65.5 million years ago. Therefor, mammoths and mastodons were abundant in the Cenozoic era.
Acanthopterygii is the superorder of fish that contains the most species, with over 13,000 species. It is a diverse group that includes many familiar fish such as perch, snappers, and groupers.
Why does the ductus arteriosis close off after birth?
The ductus arteriosus closes off after birth due to the increase in oxygen levels in the blood, which causes the smooth muscle in the ductus arteriosus to contract and constrict the vessel. This closure is essential to redirect blood flow away from the lungs, which are now functional after birth, and help establish the pulmonary circulation.
Why do most zoologist choose to be a zoologist?
Most zoologists are passionate about animals and interested in studying their behavior, habitats, and conservation. They are drawn to the field to learn more about the natural world, contribute to animal welfare, and make a difference in conservation efforts. Additionally, the versatility and variety of potential career paths in zoology, such as research, education, and wildlife management, appeal to many aspiring zoologists.
Is Steve erwin a famous zoologist?
Steve Irwin was a famous wildlife expert and conservationist, known for his work with animals as a television personality. He ran the Australia Zoo and hosted the TV show "The Crocodile Hunter," where he showcased his passion for wildlife and education about animals. While he wasn't a traditional zoologist with a formal scientific background, he made significant contributions to wildlife awareness and conservation.
Does a male bee have a father?
When a queen bee lays an egg she usually fertilizes it with a sperm she received on her mating flight. However, when she lays an egg in a drone cell she will not fertilize it.
Bee eggs will develop whether or not they were fertilized, but the result is very different. Fertilized eggs will always develop into a female (all worker bees are female), and unfertilized eggs will develop into a male.
This means that males will only carry genes from the queen, not from any drone she mated with.
Drones may not have a father, but they do have a grandfather.
Diploblasts are organisms that develop from two primary germ layers during embryonic development. These layers are the ectoderm (outer layer) and endoderm (inner layer), with no mesoderm present. Examples include cnidarians like jellyfish and coral.
Does Clemson University have zookeeping programs?
Clemson University does not offer a specific zookeeping program. However, they do offer degrees in wildlife and fisheries biology, which could provide a foundation for a career in zookeeping. It would be beneficial to gain experience through internships or volunteer work at zoos.
What IGCSE subjects should you choose if you want to become a zoologist?
Maths and English are what most courses will require you to have, as well as three other passes. Biology, Chemistry, Physics and Geography are also good to have! Try looking into university courses to see what they require.
Who are Kitty Fossey and George Fossey?
They were the parents of Dian Fossey, who is famous for having studied gorillas in Rwanda.
Does the freshwater hydra have a medusa stage in its life cycle?
No, the freshwater hydra does not have a medusa stage in its life cycle. The hydra belongs to the class Hydrozoa, which typically do not have a medusa stage like other cnidarians such as jellyfish. Instead, hydras reproduce asexually by budding.
What is the usual site of the fertilization of an egg cell?
The usual site of fertilization of an egg cell is the fallopian tube, specifically the ampulla, which is the widest part of the tube. Sperm typically meet the egg in this location, where fertilization occurs before the fertilized egg moves down the fallopian tube towards the uterus for implantation.
What is an example of a protostome?
An example of a protostome is a snail. Protostomes are organisms in which the blastopore, the opening of the developing embryo, becomes the mouth of the adult organism.
What level of organization do cnidarians belong?
B for Plato users
but it is a tissue level of organization
The vaquitas are not extinct but they are an endangered species
Large animal vets typically work with livestock animals such as cows, horses, sheep, and pigs. They provide medical care, perform surgeries, administer vaccinations, and offer preventative care to keep the animals healthy. Large animal vets may also perform reproductive services and consult on farm management practices to maintain the well-being of the herd.
A zoologist is a scientist who specializes in the study of animals and their behavior, physiology, and habitats. They may focus on a specific group of animals or study a wide range of species in various environments. Zoologists play a crucial role in wildlife conservation, education, and research.
Where in the body do chickens have their kidneys?
Kidneys are situated on dorsal side each on either side of vertebral column in the cavities of pelvis region.
Zoologists wear brown because it is a neutral color that helps them blend in with their natural surroundings when observing animals in the wild. This minimizes the chances of startling or disturbing the animals.
Is long hair in dogs a dominant trait?
Genetics is incredibly complicated microbiology, and this is an extremely oversimplified introduction to very basic genetic concepts. Please keep that in mind as you read through this page. Many people have dedicated their entire careers to the study of genetics, and much is being learned on a daily basis in the continuing field of genetic research.
Genes, the unit of heredity in cells, are inherited from one's parents. They are made up of pairs of alleles in the individual. One gene allele is inherited from the mother (via the egg), and the other one from the father (via the sperm).
Capital letters usually indicate a dominant gene allele, or one that is "stronger". Only one dominant allele of a gene pair needs to be present for that allele to be expressed (be evident). Dominant alleles mask, or hide, the recessive ("weaker") allele. The recessive allele must be inherited from both parents in order to be expressed. In other words they must be present as a pair to be shown. Recessives are indicated with a lower case letter.
Most visible traits are produced by many genes interacting in the individual. These are called polygenic traits. But some traits are controlled by a single gene. For our theoretical simplified example, we will use a single gene trait.
A = dominant allele a = recessive allele
If A indicates short hair in a dog, for this example, and a indicates longhair, then:
AA would be a shorthaired dog with no longhair recessive.
Aa would be a shorthaired dog with a longhaired recessive, but you would not know it was carrying the longhaired trait by looking at the dog, since the dominant allele, A, masked the recessive allele, a.
aa would be a longhaired dog , since the recessive alleles must be present in a pair to be expressed, however please see * Note below regarding the quantity of hair likely to be present in such a dog that had an Aa parent. As can clearly be seen, it is not possible for the aa dog to carry or pass on the dominant trait, which for this example, is shorthair..
Forget all that ! I have been breeding dogs for over 55 years and i can tell you that the long coated dog is a dominate. If you breed 100 years of short coats and you breed one long coat into your short coat, you will get short coats, but if you choose the long coat pup and breed back to your long coat you will get a majority of long coats. Then you breed all long coats for 100 years and bred to a short coat you will retrace your steps in reverse. Once you have long coats you will never ever get a short coat unless you 'outcross' to a short coated breed. example is the American Cocker spaniel which can never go back to its former look. The judges and breeders chose to go with the long coat and now, you will never be able to get what the standards call for. All American Cockers should be thrown out of the show rings for non conformation to the standards of their breed. your answer is YES
