Answer:
plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.
Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.
Transcript of EXCRETORY SYSTEM OF THE FROG AND HUMANTHE URINARY SYSTEM IS RESPONSIBLE FOR THE ELIMINATION OF WASTS VIA THE URINE. THE BASIC UNIT OF FUNCTION IS THE NEPHRON COMPOSED OF THE GLOMERULUS AND A SERIES OF TUBULES RESPONSIBLE FOR THE EXCRETION OF WASTES, REABSORPTION OF VALUABLE SUBSTANCES, AND FILTRATION OF BLOOD.

EACH KIDNEY CONTAINS UP TO 18 LOBULES AND THOSE 18 LOBES CONTAINS NEPHRONS ARE THE FUNCTIONAL UNIT OF THE KIDNEYS AND EACH KIDNEY CONTAINS MORE THAN 1 MILLION NEPHRONS. IN THE NEPHRONS COMPOSED OF GLOMERULUS FILTERS THE BLOOD LEAVING THE FILTRATE INSIDE THE GLOMERULAR SPACE. THE FILTRATE HAS SIMILAR CHARACTERISTICS TO PLASMA EPT IN THE PRESENCE OF PROTEINS IN THE FORM OF ALBUMIN. THE FILTRATE THEN GOES INTO THE PROXIMAL CONVOLUTED TUBULES WHERE MAJORITY OF THE SUBTANCES ARE REABSORBED.
KIDNEY
THE FLUID ENTERS THE DESCEDING LIMB OF HENLE WHERE IT IS IMPERMEABLE TO MINERALS AND OTHER SUBTANCES. THEREFORE, THE FLUID INSIDE THE TUBULES BECOMES HYPERTONIC COMPARED TO PLASMA. AS THE FLUID INSIDE GOES UP INTO THICK ASCENDING LIMB OF HENLE, WATER BECOMES IMPERMEABLE. THUS, IT IS ONE OF THE IMPORTANT DILUTING SEGMENTS OF THE URINARY SYSTEM. THERE IS ACTIVE TRANSPORT OF VARIOUS PHYSIOLOGICALLY IMPORTANT IONS SUCH AS POTASSIUM IONS, SODIUM IONS AND OTHERS.

LIQUID WASTE GENERATED BY THE KIDNEYS TRAVELS THROUGH THE MESONEPHRIC DUCT INTO E CLOACA. SOLID WASTE FROM THE LARGE INTESTINE PASSES INTO THE CLOACA. BOTH SOLID AND LIQUID WASTE MATERIALS LEAVE THE BODY THROUGH THE ANUS, THE ONLY OPENING FOUND IN THE POSTERIOR PART OF THE BODY.
THE FLUID THEN GOES INTO THE THIN ASCENDING LOOP OF HENLE AND INTO THE DISTAL CONVOLUTED TUBULE WHERE WATER AND SODIUM REABSORPTION IS EFFECTED BY ALDOSTERONE SECRETION BY THE ADRENAL CORTEX. THE FLUID THEN GOES IONTO COLLECTING TUBULES WHERE WATER REABSORPTION IS AFFECTED BY ADH.SOME REABSORPTION OF IMPORTANT IONS STILL OCCURS IN THESE FINAL SEGMENTS.
THE NEPRON
FINALLY, THE URINE DRAINS INTO THE MINOR AND MAJOR CALYX TO GO INTO THE RENAL PELVIS. FROM HERE IT IS DRAINED BY THE URETER TO BE TEMPORARILY STORED IN THE BLADDER WHERE PERIODIC EMPTYING OCCURS VIA THE URETHRA THROUGH THE PROCESS OF URINATION. THE URETHRA CONNECTS THE URINARY BLADDER TO THE GENITALS FOR THE REMOVAL OF URIE OUT OF THE BODY.

Author's use of details convey to Eleanor Rossevelt life and legacy are described below.
Explanation:
1.She advocated for expanded roles for women in the workplace, the civil rights of African Americans and Asian Americans, and the rights of World War II refugees. Following her husband's death in 1945, Roosevelt remained active in politics for the remaining 17 years of her life.
2.The fireside chats were a series of evening radio addresses given by U.S. President Franklin D. Roosevelt (known colloquially as "FDR") between 1933 and 1944.
3..President Theodore Roosevelt, an Oyster Bay Roosevelt, was the uncle of Eleanor Roosevelt later wife of Franklin Roosevelt. Despite political differences that caused family members to actively campaign against each other, the two branches generally remained friendly.
4.Champions of Human Rights. Eleanor Roosevelt (1884–1962)
- Continuing her work on behalf of all people, she advocated equal rights for women, African-Americans and Depression-era workers, bringing inspiration and attention to their causes.
The plant cell is the smallest living structure and constituent unit of all plants. Its size and shape vary by function. It is composed of several organelles, all useful to its activity.
The right answers are: (the numbers are in the picture).
1 refer to a vacuole.
2 refer to a cell wall (if you see closer, the arrow is aiming the green layer, the yellow one is the cell membrane).
3. refer to a chloroplast.
4. refer to mitochondria.
<u>Answer:</u>
<em>The interaction the cattle egret exhibits with the buffalo is commensalism.
</em>
<u>Explanation:</u>
<em>In the type of interaction called commensalism</em> between two organisms, one organism benefits from the other while the other <em>organism is neither benefited nor harmed. </em>
When the buffalo moves around a field grazing it disturbs the insects and they fly away from the buffalo and the cattle egret which keeps following the <em>grazing buffalo eats the insects.
</em>
The buffalo doesn’t benefit from this type of interaction. <em>A commensalism relation is a positive-neutral kind of relation.
</em>
