I cannot find the list of molecules and organs, but I gonna explain all existing lipid digestion.
First, you should know that triglycerides are not absorbable. The absorbable substances are free fatty acids, monoglycerides and cholesterol.

The main stages of lipid digestion:-Fat emulsification;
-Hydrolysis of lipids (by enzymes);
-Formation of micelles;
-Endocytosis of the micellar contents.

The enzymes responsible for lipid hydrolysis are:
lipases (pancreatic): secreted by the exocrine pancreas
colipase: secreted by the pancreas in an inactive form. Its role is to help the lipase in its activity.
cholesterol esterase: secreted by the pancreas too.
phospholipase A2: exists in the majority of the cells

1) a) In ONE sentence only, how is telomerase activity different from DNA polymerase activity during DNA elongation? b) In ONE s
Ipatiy [6.2K]
1. During DNA elongation, polymerase enzyme adds new, free nucleotides to the three prime end of the newly forming strand, elongating it in  five prime to three prime direction while the telomerase protects the important genes at the end of the chromosome from been deleted as the DNA strand shorten during DNA elongation.

2. During DNA elongation, helicase enzyme separates the double stranded DNA  into single strand by melting the hydrogen bond that holds the DNA molecule together thus enabling each strand to be copied while the telomerase acts by preventing the telomere from been deleted during elongation.

A researcher has developed two stains for use with seed plants. One stains sporophyte tissue blue; the other stains gametophyte
sukhopar [10]

Answer:

A) The pollen grains will be pure red.

Explanation:

Plants have alternation of generations, this means that there are two different stages in their life-cycle: a sexual haploid (n) phase and an asexual diploid phase (2n). These phases occur in different individuals, so there is an haploid plant called gametophyte that carries gametes and after fecundation, it will rise a diploid sporophyte (asexual).  

In seed plants, the sporophyte is the plant that we normally see, and the gametophyte is reduced into an organ of the sporophyte. The male gametophyte is the pollen that is produced in the sporangium in anthers (parts of sporophyte).  When a pollen grain fecundes a female gametophyte (egg), it will produce a diploid embryo or new sporophyte.

Therefore, if the researcher exposes pollen to both stains, these grain will stain red, because red stain identifies gametophyte tissue.
