Scientific thinking: how can scientists assess the health risks of trans fats
Klio2033 [76]
Scientists can access the risks of trans fats by conducting an appropriate experiment which will show the effects of the fats on the human system.
This can be done by feeding known quantity of trans fats to rats over a specific period of time. During the period, the change in the rat weights will be measured on the daily basis and every other changes that is noted in the rats will be noted down. A control group of rats will be included in the experiment; these rats will be given normal rat feeds and not trans fats.
 When the period of feeding is completed, the rats will be killed, all the organs in the rats such as liver, blood, brains, kidney, etc will be harvested and these organs will then be biochemically analysed in order to compare the changes in them with that of a normal rats.
Rats are usually used in biochemical research because their systems and that of human is comparable. Any negative effect of trans fats that is noted in the rats will also hold true for human beings.

What causes oxygen to diffuse from the lungs into the capillaries?
malfutka [58]

Answer:

Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.

Dimples (D) and brown hair (A) are dominant traits. Answer the following questions based on the dihybrid cross shown:
ira [324]
1. DDAA, DdAa
2. DDaa, Dada
3. ddAA, ddAa
4. ddaa
5. The phenotypic ratio is 9:3:3:1 where 9 combinations will produce offspring with both dominant phenotypes (dimples and brown hair), 3 will produce offspring with one dominant phenotype and one receive phenotype (dimples, blonde hair), 3 will produce offspring with one receive phenotype and one dominant phenotype (no dimples, brown hair), and one will produce offspring with both recessive phenotypes (no dimples, blonde hair)

Why do organisms require different levels of cellular organization
Andru [333]
A unicellular organism must perform all functions necessary for life. A multicellular organism has specialized cells, tissues, organs, and organ systems that perform specific functions.

explain how a change in the sequence of nucleotide in a strand of DNA might cause a protein to malfunction
Diano4ka-milaya [45]

Answer: Proteins are made using DNA as a template. The DNA is turned into RNA, and the RNA is then turned into DNA. 

A change in these nucleotides could end up making some part of the protein different. A single nucleotide change could be silent (no change in the protein) or could change a single amino acid (amino acids are the building blocks of proteins). If that was an important amino acid, the protein might not function at all! A silent change can occur because the same set of nucleotides sometimes makes the same final amino acid (for example, reading "gcc" "gca" "gcg" or "gct" nucleotides all mean "alanine" amino acid). 

The deletion of a single nucleotide, or the addition of one, can change the entire sequence of amino acids that come after it! Nucleotides are read in sets of three, so this throws off how the DNA is read. If would be like turning "The brown fox jumps over the dog" into "The gbrow nfo xjump sove rth edo g". Completely different! All of the words are thrown off.

I know it is long but I hope it helped
