Life is for some of us efficient, long, worthy process during which we achieve smth., struggle for smth and for sure learn a lot, unfortunately for some of the people life loose the sense and people don't see its beauty. According to the dictionary life means "The physical, mental, and spiritual experiences that constitute existence".
Your hometask for this lesson includes 3 tasks:
1. Watch the video from the link the beginning of life and answer the following questions:
a) What is the role of the cell?
b) Explain the meaning of "eucaryote"
c) What did the reporter say about the black marks on the video?
d) How many times are bacteria smaller than the size of the cell?
e) How many years ago appeared the complex cells?
f) Explain the word jerk and provide read by you links about "evolution of jerks"
g) what is the role of DNA?
h) What kind of "marriage" happened many years ago?
i) What happened after the complex cells appeared?
2. Read from the link about 7 theories of the beginnings of life http://www.livescience.com/13363-7-theories-origin-life.html, write about one that you consider got the highest probability to happen.
3. Design a poster illustrating your feelings about life in general.
Tasks for the second lesson appeared already, read the tasks and answer in 3 posts please!!!!, don't forget to comment posts made by your colleagues

Deletea)The cell is the basic, structural and functional, of all living organisms.
ReplyDeleteb)The domain Eukaryota or Eucaryotes1 (from the Greek eu, good and karuon, core) includes all multicellular organisms uni-or characterized by the presence of a nucleus and mitochondria in their cells, and opposes the areas of Eubacteria and Archaea.
According to the nomenclature of Whittaker (1978) 2, eukaryotes together four great kingdoms of the living world: animals, fungi, plants and protists, which should be added according to the nomenclature of chromistes Cavalier-Smith (1981 ) 3. However, the relevance of these kingdoms is challenged by modern phylogenetic studies, it is now better to use only monophyletic taxa.
c)
d) bacterium ~ 10-100 μm (sperm cells, apart from the tail, are smaller)
cell - small - less than 1 μ - Streptococcus, Staphylococcus
medium - between 1 and 3 μ μ - Salmonella, Bacillus Coli
large - more than 3 μ - clostrydium
e)Complex cells likely arose from bacterial microbe genes Extreme
f)DNA stands for deoxyribonucleic acid. It consists of the most complex organic molecules. Substance found in every cell of living things and is essential to the identity of any body of Euglena viridis, small unicellular creature bordering between plants and animals, and to Homo sapiens sapiens, modern man.
It is very good that you've heard so much information in this video.

ReplyDelete1.The cell is to multiply and destroy microbes. Cells are slowly growing and most developed.
2.
3.Tiny black points are bacteria that are very small and try to confront large cells.
4.A thousand times smaller than cells.
5.They appeared in the first billion years old .
6.
7.Send genetic codes.
8.
9.Everything began to be developed and smarter it was a inportant event.

ReplyDeleteChilly StartIce might have covered the oceans 3 billion years ago, as the sun was about a third less luminous than it is now. This layer of ice, possibly hundreds of feet thick, might have protected fragile organic compounds in the water below from ultraviolet light and destruction from cosmic impacts. The cold might have also helped these molecules to survive longer, allowing key reactions to happen. My opinion is that this legend may have little chance of being correct.
interesting theory. It might happened.
DeleteI agree with your opinion
Deletea) Cell role is to keep the energy of our organism.
ReplyDeleteb) eucaryote - an organism with cells characteristic of all life forms except primitive microorganisms such as bacteria; i.e. an organism with `good' or membrane-bound nuclei in its cells.
c)
d)thousands of times.
e)2 billion years ago.
f) A sudden abrupt motion, such as a yank or twist.
g)DNA keeps our genetic codes
h)One cell gets into another cell this is called marriage
i) A fast development of the world had began.
Instead of developing from complex molecules such as RNA, life might have begun with smaller molecules interacting with each other in cycles of reactions. These might have been contained in simple capsules akin to cell membranes, and over time more complex molecules that performed these reactions better than the smaller ones could have evolved, scenarios dubbed "metabolism-first" models, as opposed to the "gene-first" model of the "RNA world" hypothesis.
ReplyDeleteinteresting theory

ReplyDeleteI think I would choose second theory "Simple Beginnings", because this theory seems to be more feasible. Of course there may be other theory that would explainn how life apperead on earth. Scientific searches assume tht our planet is 4,6 to 4,8 billion years old and the first living thing apperead about 3,5 billion years ago a filamentous bacteries.

ReplyDeletea)Cell are designed to multiply and destroy microbes
b)
ReplyDeleteC)black dots are very small bacteria that are trying to deal with large cell
d)bacteriile sunt de o mie de ori mai mici ca celulele
ReplyDeleteE)complex cells appeared 2 billion years ago
f)
g)DNA's role is to keep sending our genetic codes
h)marriage is when one cell into another cell becomes
i)was an important event because it started a rapid development of the world

ReplyDeleteDepth of ventilation theory suggests that life may have begun in submarine hydrothermal vents, spewing key hydrogen-rich molecules. Their rocky corners could have focused then these molecules together and provided critical catalysts for reactions minerals. Even now, these vents, high chemical and thermal energy, sustain vibrant ecosystems. My guess is that this legend is not correct
a)The cells are designed to form a body and keep its energy.
ReplyDeleteb) Eucaryotes1 includes all multicellular organisms uni-or characterized by the presence of a nucleus and mitochondria in their cells, and opposes the areas of Eubacteria and Archaea.
c)Black bacteria are bacteria that try to swallow.
d)Very small.
e)Complex cells appeared millions of years ago.
f)---
g)The role of DNA is to differentiate living organisms.
h)Many years ago there was the union of two cells.
i)There has been rapid development of the world.
2)Electric sparks can generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia and hydrogen, as was shown in the famous Miller-Urey experiment reported in 1953, suggesting that lightning might have helped create the key building blocks of life on Earth in its early days. Over millions of years, larger and more complex molecules could form. Although research since then has revealed the early atmosphere of Earth was actually hydrogen-poor, scientists have suggested that volcanic clouds in the early atmosphere might have held methane, ammonia and hydrogen and been filled with lightning as well.I think it would be a stupid idea of how many lightning electricity could influence life on earth.
