stellarik [79]

Answer:

Genotype of long winged fly is Ll

Genotype of short winged fly is ll

Explanation:

Given

Allele for long wing trait is "L"

Allele for short wing trait is "l"

When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is 1:1

Let us say that the genotype of long winged fly is Ll

and the genotype of short winged fly is ll

The cross between the two will produce following offspring

Ll * ll

Ll, Ll, ll, ll

Out of four off spring two have long wings (Ll)

and the other two have short wings (ll)

Thus the ration of long to short wing offspring is 2:2 i.e 1:1

What is the function of lipoprotein lipase?
scZoUnD [109]

Answer:

Hydrolysis of triglycerides in lipoproteins

Explanation:

Lipoprotein lipase is a water-soluble enzyme which includes pancreatic lipase, hepatic lipase, and endothelial lipase.  

Enzymes involved in triacylglycerol digestion are lipases and they catalyze the partial hydrolysis of triglycerides into a mixture of free fatty acids and acylglycerols. After digestion of lipids, monoglycerides and fatty acids associate with bile salts and phopholipids to form micelles. Micelles are structures that are necessary for the transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte. But, micelles cannot be absorbed by epithelial cell, only freely dissolved monoglycerides and fatty acids can.
