There are no multicellular plants in the oceans Most are photosynthetic single cells Cambrian is in Paleozoic era Called Cambrian explosion‚ because in this 70 million years. We have an explosion of every multicellular organism. Wednesday October 31st‚ 2012 CAMBRIAN Phanerozoic Eon Eras: Paleozoic (most recent : 550 Ma until now) – multicellular organisms in the oceans The periods in the Paleozoic era are: Cambrian Ordovician: end is one of the 5 mass extinctions. So many organisms

Contrary to popular belief‚ our brains do not reach adulthood and stop changing or growing. Although there are limitations‚ such as our inability to heal brain damage the way we heal other body parts‚ human brains continue to generate new neurons well past when was originally thought. This process is called neurogenesis‚ and until recently‚ was seen as a development only occurring in embryonic and perinatal stages in mammals. Luckily‚ this continues throughout life‚ and is beneficial to college

Stem Cell Research: Should we continue to allow scientists to create new embryonic stem cell lines? Good morning everyone. The topic of Stem Cell Research has been argued over by politicians‚ scientists and people all over the world for over a decade. Scientists should not be allowed to continue to create new embryonic stem cell lines. One of the ways to obtain stem cells for scientific research is to destroy a blastocyst (laboratory-fertilized human egg). Destroying the blastocyst is the equivalent

1. Explain broadly‚ what ‘3D Imaging’ is. You must identify the hardware and software typically associated with this field. 3D imaging is a process where there are two different images and they are put together to make give a three-dimensional feel to the single image. 2. Describe at least three areas that 3D imaging is used. You need to describe in detail The nature of the technology in relation to the specific area. This means you need to Elaborate on how the technology being is used‚ explaining

Introduction/Research Question The researchers are attempting to find if certain FVEP-P2 (electroencephalographic component of the flash visual evoked potential) procedures have enough diagnostic accuracy to determine who has amnesic mild cognitive impairment (MCIa)‚ which has been shown to lead to Alzheimer’s dementia (AD)‚ and who does not. This could change the way doctors discover MCIa and could lead to an increase in the potential for medicines or procedures that could prevent AD to be developed

Embryonic Stem Cell Research is an important process that is already allowing scientists to test new drugs and figure out the cause of birth defects. The process is very delicate because scientists must work with a four to ten day old blastocyst to get the stem cells. They put the stem cells into a petri dish along with proteins and enzymes. The stew of cells‚ enzymes‚ and proteins is what helps regenerate the bad tissues that cause diseases. “Blastocysts can also potentially be created from a donor

Over the years technology has advanced in many ways. Some ways for the good and some ways for the bad. In both of the articles I learned about two advances and how they are useful. Even though the technology advancements might be useful there are still some cons to these advancements. To start off‚ since the early ancient civilizations the ray of light was believed to possess mystical and magical powers. The early people believe a ray of light was a message from God or it could heal people

EEGs Clinical psychologists and neuroscientific researchers have always sought to understand what is going on in the brain and what is on the mind of their clients. For centuries‚ direct examination of the brain was elusive and almost nearly impossible due to the inadequacy of technology. However‚ noninvasive advances in brain examination have alleviated those challenges‚ making it possible to explore and investigate the brain in depth. Electroencephalography (EEG) is used to monitor and test electrical

Pros: Embryotic stem cells could cure numerous diseases‚ and provide organs to people on the transplant list. Because of the high demand of organs‚ innumerable people die waiting for a transplant. If scientist discover how to create organs‚ lives will be saved. There is research that shows that it could be possible to use the patient’s own cells instead of embryonic stem cells. Cons: There are concerns with obtaining stem cells. Stem cells are acquired from human embryo or fetus‚ and can cause birth

From the time of ancient Egyptians the prosthetics were created to help the amputees and giving them a feeling of wholesome. The earliest recorded prosthetic comes from 15th century B.C which was made of wood and leather and it was used to replace toes of an amputees. Prosthetics and bionics have always helped people recover from their disabilities and gave them a chance to live a better but not completely normal life. In 21st century new experts with new ideas are making prosthetics and bionics
