Answer: White pulp of the spleen
Explanation:
The white pulp of the spleen is that region found in the spleen which appears white in color.
It appears whiter than the surrounding red pulp on the gross section which consitutes to about 25% of the whole splenic tissue.
This area has antigen presenting cells and dendritic cells and macrophages. Some of the cells there are known as metallophillic mcrophages which helps in keeping the body free from diseases.
The type of molecules that contains the alcohol glycerol are PHOSPHO-LIPIDS.
Glycerol is a three carbon alcohol on which some phospholipids are built. Phospholipids which are derived from glycerol are called phosphoglycerides.
Answer:
genes for flower color and edge shape are linked. They do not assort independently.
Explanation:
<u>Available data:</u>
- test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
- serrated leaves → dominant trait
- smooth edges → recessive trait
- purple color → dominant trait
- white color → recessive trait
- F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.
There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.
To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent
