After surgical removal of the spleen (i. e., a splenectomy), some other organs take over most of its functions. Which of the following spleen functions in the adult can not be performed by bone marrow? A) immune surveillance
B) erythropoiesis
C) removal of aged and damaged red blood cells from the blood
D) storage of platelets

removal of aged and damaged red blood cells from the blood

Explanation:

Spleen is an organ found in vertebrates and it is located in the upper part of the abdomen that act majorly to filter blood. It recognizes and removes old, malformed, or damaged and aged red blood cells. When blood flows into the spleen, the spleen performs "quality control"; the red blood cells must pass through a maze of narrow passages.

The bone marrow is a spongy tissue that produced red blood cells and this perform similar function as the spleen except that it cannot remove aged and damaged red blood cells from the blood this is because it does not have the ability to remove age and damage red blood cells due to inability to support the immune system.

The spleen help remove age and damage red blood cells thereby boosting the immune system in fighting against infections ,preventing blood clot .

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
