I've been thinking about your next assignments and I had a great idea. For you to review everything we have been discussing so far, I would like you to:
1) Write a journal entry (as if it were in your personal diary) of around 220 words on how your life changed since you were a carbon molecule floating in the atmosphere till you became a human being. Remember to include all the theories on life.
I'm including a link for you to download the .doc version of the journal for you to write on.
https://drive.google.com/open?id=1NpR2UP1mr-TDZx3gN6DzXiDGTUJA2Wv4
The due date will be May 28th.
I'm uploading my powerpoint presentation on ORIGIN OF LIFE for you to revise the concepts.
You can also watch the videos on my previous post https://biologics32020.blogspot.com/2020/04/and-god-said-let-there-be-light.html
2) For Monday 18th you will have to mail me your tweet, explaining in 280 characters why I chose the phrase that sums up the unit
Here you have a link to a tweet generator for you to prepare yours.
https://www.tweetgen.com/create/tweet.html
and last but not the least..
3) Who are we? Are we clones of ouselves? Can we be alive & dead at the same time? I would like you to watch this super cool video and answer some questions on its content. You have time to answer it until May 20th at midnight. (it's my first attempt with Edpuzzle so it will have its problems. Be patient with me, please)
And in case anyone wants a 10, you can answer my new #CHALLENGE on species that acompanies this post

1) No, they didn’t get the embryo to term because the experiment was stopped at four weeks gestation, to evaluate the safety and efficacy of the technology up to that point. But human cells didn’t grab. They saw the cells contributed very little to the development of the embryo.
ReplyDelete2) They did this in order to transplant the organs into a human being who needs it. It will also allow us to better understand the development of a human being, it will help us find new drugs to treat diseases and even to better understand the evolution of organs in the human species.
3) They are crossing species.
-Genera: It is a group of organisms that in turn can be divided into different species.
-Kindoms: Each one of the great divisions in which natural beings are considered distributed, by reason of their common characters.
-Families: Is a systematic unit and a taxonomic situated between order and genera.
-Classes: It is a taxonomic category situated between the edge or division and order.
-Species: Set of people or things similar to each other for having one or more common characteristics.
4) The chimera is an individual who has cells that are genetically distinct. They are from different individuals.
No, chimera and hermaphrodite is not the same. Hermaphrodite is when a person has both sexes, while chimera is when a body is made up of different individuals, not necessarily of different sex.

ReplyDelete1-No, they didn`t get the embryo to term because the human cells didn`t grab to pig cells and they also contributed very little to the development of the embryo.
ReplyDelete2-They do this to transform other species in transplant organs factories. They were looking for generation of cells with the capacity of creating human organs in animals.
3-Yes, they are crossing different kind of species (human: Homo Sapiens- pig: Sus crofa) and families (Hominids human; Suidae, pig).
Genera: is a taxonomic rank above species and below family. Composed by species that are structurally similar or phylogenetical related.
Kingdom: is the highest taxonomic rank (each level inside de hierarchy) in classifying organism. It is divided into 3 small groups called phyia (animal, mineral and vegetable), in the classification of species, is the second thing you have to identify.
Families: is a taxonomic rank between genus (above) and order (below). It has one or more genera, sharing a common attribute. Also, organisms being part of the same family would have evolved from the same ancestors and share common characteristics.
Classes: is a taxonomic group composed by organisms that share a common attribute. It is divided into one or more orders.
Species: is the lowest taxonomic rank, and the most basic category of biological classification. Species have 2 names: the generic name (Human) and the scientific name (Homo Sapiens).
4- Chimera is organism composed of two genetically different types of cells. They can be formed by the fusion of two early blastula stage embryos or by other processes. No, hermaphrodite is not the same as chimera because hermaphrodite is an organism that has both male and female organs, that is why, is capable of producing both male and female gametes.
In humans, the term hermaphrodite is used to describe an individual possessing both male and female organs but one of the two gonads present may not be functional However, a true hermaphrodite refers to an individual in which both gonads are functional.

Delete1-No, the embryo did not get to term since they stop this project when the first trimester of pregnancy ended. They stop it because they thought that bringing to the world an animal with human cells would be a great controversy in the scientific field. 2-The idea of this project is to generate animals that have organs made entirely of human cells. That animals could be used as sources of organs for transplants. 3-Yes, they are crossing different species. This groups are in the Binomial Nomenclature: Species: The Group of organisms that can reproduce in nature and generate a fertile offspring. Classes: were the most general rank proposed by Linnaeus. There are 108 different classes in the kingdom Animalia, including Mammalia (mammals), Aves (birds), and Reptilia (reptiles), among many others. The classes of Animalia that Linnaeus proposed are like the ones used today. Family: is more specific than the others. Some families in the order Carnivora, for example, are Canidae (dogs, wolves, foxes), Felidae (cats), Mephitidae (skunks), and Ursidae (bears). Kingdom: Before domains were introduced, kingdom was the highest taxonomic rank. In the past, the different kingdoms were Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria. Genus: is even more specific than family. It is the first part of an organism’s scientific name using binomial nomenclature; the second part is the species name. 4- The chimeras are embryos with genetic information of different species. They are formed from cells and tissues of different individuals. Each population of cells keeps its own character and the resulting organism is a mixture of tissues. While, the hermaphrodite means that an individual has two organelles: one female and the other male.
ReplyDeleteNo, the embryo did not get to term because one of the scientists decided to stop the procedure, as there were lots of previous steps to take. The reason why they started the experiment in the first place, was because they wanted to prove that human cells can not only survive, but also grow when put inside a non-human organism. By doing this they are crossing kingdoms. When it comes to divisions we could be talking about genera, a taxonomic order used in the biological classification of living and extinct species and in the biology of viruses. In the biological classification Hierarchy; kingdoms, taxonomic group formed by smaller classes, of plant divisions. A kingdom is traditionally the most overall taxon used in categorization of organisms; families, A taxonomic category in the classification of genus-order species; classes, the most general division, which includes Mammalia (mammals), Aves (birds), and Reptilia (reptiles), among many others; and last but not least, species, a basic taxonomic classification group, listed below a genus or a subgenus.
ReplyDeleteA chimera is an entity whose body is composed of genetically distinct cells, as if they belong to different individuals, and they often do belong to different individuals. Now, a chimera could be a hermaphrodite, since the different DNI entered could also be human, but it could also not be.

Deletepirates challenge
ReplyDelete1-In this example I can see sensitivity, which is the ability to detect or sense changes in the environment and to make responses. I think that it is this characteristic as pirates go from places with light to dark ones and from darkness to light and their eyes had to adapt to the conditions.
2-The eye patch help them because it was easier for the pupil to adapt the illumination changes from a sunny light to a dark one. They always had an eye with an eye patch, and that eye was the one adapted to darkness so if they had to go to dark decks or for example in a battle they had to go to a dark zone, they only had to change the patch from one eye to another, that is why they had guaranteed a kind of immediate night vision.
3-In the case of going from the dark to light it was not useful because it is easier to the eyes to adapt. It only take seconds to the eye to adapt to light. On the other hand, it takes about 25 minutes or more to the eye adapt to darkness. it was not useful because both eyes were adapted to darkness, the one that you are seeing in the dark decks is adapted to dark and don`t forget that the other eye is covered by the patch so it is also adapted to darkness.
In the picture, I can see the ability to detect or sense changes in the environment (stimuli) and to take responses which is called sensibility.
ReplyDelete2- There are two types of receivers, one is used for day vision(cones) and the other one for night vision (rods). The first one is stimulated by light and the second by the lack of it. So, in the eye covered, the lack of light will always stimulate the night receivers, therefore, their night vision. So, when it is night and under threat, the patch is changed to the other eye in order to not waste time getting used to the night. In this way, they can be more prepared to avoid an attack.
3- It is not very useful because they had both eyes adapted to the darkness and it takes 25 minutes or more to adapt the eye to the light. What is more , in that time, they were not in position to protect their selfs so they became an easy target.
