Answer:
Some reasons that people give for smoking:
> they believe it reduces stress and anxiety ( scientific studies show this isn't factual and the chemicals within smoking products is only made appealing and or distracting to make the user believe so. It actually heightens stress levels and lowers health levels)
> this sounds cliche but, teens often think its cool or get peer pressured into it. They find themselves wanting to try harmful substances and get addicted. ( in one study there were d r u g s found in smoking products aimed to get the attention of children and young adults. It's all a marketing ploy for business men and women to collect money as you slowly grow more and more breathless)
> lastly, "it's not that bad for you" often, markets and cig stores tell potential buyers its not as bad as other things. Some say its not harmful at all.( Lung disease,gum disease,heart failure,etc. all disprove this. Each year about 480,000 people die from the affects of smoking)
Explanation:
Answer:
RER is involved in protein synthesis, folding, transport and modification.
Explanation:
The Endoplasmic Reticulum is an organnelle found in eukaryotic cells. They are of two types; Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum, so named based on the appearance of their surface. The Rough Endoplasmic Reticulum (RER) obtains it rough appearance from the membrane bound ribosomes attached to it.
Due to the ribosomes that attach to them during protein synthesis, their function is very much associated with protein synthesis. They are primarily involved in protein production, which would either remain in their lumen for further modification/processing called Glycosylation (adding sugar to proteins to form glycoproteins) or be transported through secretory vesicles to the Golgi apparatus. They also fold this proteins in their inner membrane structure called cisternae.
Answer:
carbon based molecules are four
carbohydrates, lipids, proteins, and nucleic acids. These molecules have different structures and functions, but all are formed around carbon chains and rings.
Punnet squares are used to predict the genotypes of the parents' children. on the top of the punnet square is the female's genotype. The side of the punnet square is the male's genotype. match up the letters based on the box (i don't know how to explain the inside well). Pretty much, the inside is the predictions of the children's genotype. The capitol letters are the dominant traits and the lowercase letters are the recessive traits.
