This lipid is amphiphathic . Because of this, this lipid A) contains no double bonds between carbons and is a solid at room temperature. B) contains varied functional groups to create molecules with varied functions. C) has a polar and non-polar region, making it a logical component of cell membranes. D) contains at least one double bond between carbons and is therefore, liquid at room temperature.

Answers

Answer:

The correct answer is C has polar and non polar region making it logical component of the cell membrane.

Explanation:

Amphiphatic compounds are specific type of biochemical compound that contain both polar and  nonpolar portions.

For example phospholipid molecules of the lipid bi layer of the plasma membrane.Phospholipid contain polar head group also called glycerol and 2non polar hydrocarbon fatty acid tails.Therefore lipid basically phospholipids are amphiphatic in nature.

Sense we have now found the gene that controls nitrogen uptake, do you think it would be a good idea to genetically modify crop plants to grow with less nitrogen? Why or why not?

Answers

It might not be a good idea as nitrogen may be needed by plants in several cellular processes and eliminating nitrogen uptake might severely impair these functions if there are no alternatives to these pathways

2. In dogs, there is an hereditary deafness caused by a recessive gene, "d." A kennelowner has a male dog that she wants to use for breeding purposes if possible. The dogcan hear, so the owner knows his genotype is either DD or Dd. If the dog's genotype isDd, the owner does not wish to use him for breeding so that the deafness gene will notbe passed on. This can be tested by breeding the dog to a deaf female (dd). Draw thePunnett squares to illustrate these two possible crosses. In each case, whatpercentage/how many of the offspring would be expected to be hearing? deaf? Howcould you tell the genotype of this male dog? Also, using Punnett square(s), show howtwo hearing dogs could produce deaf offspring.
