Ribosomes are microscopic machines found within all living cells. Found on the rough endoplasmic reticulum and in the cytoplasm, the main function of ribosomes is to synthesize proteins. Ribosomes are able to make proteins by “reading” information contained within messenger RNA (mRNA). The information contained within the mRNA contains the instructions for the ribosome to assemble the proteins bit-by-bit.

Proteins are made up of chains of organic molecules called amino acids. Ribosomes grab amino acids and link them together to create proteins in a process termed translation. During translation, every protein must be folded correctly in order to function properly.

Another of the ribosome's function is to mediate the proper folding of proteins.

Select the correct text in the passage.
masya89 [10]

Answer:

the actual REAL answer would be, Parthenogenesis involves the formation of a zygote.

 Explanation:  Formation of a zygote is the step in both, sexual and asexual reproduction. Both modes of reproduction tend to continue the lineage of life forms and to pass on genetic material on their offspring.

What are some ethical issues related to cloning?
Keith_Richards [23]

Answer:

A preocupação com a abordagem das questões éticas dos processos de clonagem não é recente. Desde a década de 1970 vários autores tem discutido diferentes questionamentos a respeito dos aspectos éticos envolvidos.

Quando se fala de Clonagem Humana, a maioria das pessoas pensa logo na criação de seres humanos idênticos a outro, mas a clonagem humana não é só isso.

A Clonagem Humana pode ser reprodutiva ou não reprodutiva (terapêutica). A primeira tem por objectivo criar um ser geneticamente idêntico a outro, como um gêmeo. A segunda tem por base a criação de órgãos e tecidos para fins terapêuticos.

A Clonagem Humana é apoiada pelos cientistas, enquanto as políticas, as religiosas e as morais, criam barreiras para clonagem humana, as quais formam um dos grandes temas do questionamento ético actual.

Igreja católica defende a existência de vida humana, desde a fecundação, como algo divino. "A vida humana é um dom de Deus, só Ele é senhor da vida,”  Não é permitido, destruir um embrião para obter células tronco, nem abreviar a vida de um ser humano para extrair órgãos para um transplante, a fim de salvar outra vida. Assim, a clonagem com finalidade terapêutica é rejeitada pelo catolicismo, pois quando se trata de extrair células tronco de um embrião acaba-se infringindo o mandamento"Não matarás". "O embrião já é uma vida, que deve ser respeitada por inteiro.”

Segundo a Sociedade Bioética a Clonagem Humana é antiética, pois crê não ser preciso desenvolver embriões para depois destrui-los uma vez que afirma que existem técnicas alternativas para se obter células-mães, como por exemplo o aproveitamento das células do cordão umbilical dos recém-nascidos, que é repleto de células que podem ser utilizados para a regeneração de tecidos.

Já a Sociedade tem o medo de que um clone não seja um “indivíduo” mas meramente uma cópia de “carbono” de alguém criou um sentimento de ofença mental pois a representação mental foi rapidamente configurada a bebês produzidos numa “fábrica biológica”.

F. Why are there more producers in the world than top carnivores?
Rainbow [258]

Answer:

There is only enough food for a few top level consumers

Explanation:

The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer. Therefore, the energy transfer from one trophic level to the next, up the food chain, is like a pyramid; wider at the base and narrower at the top. Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.
