The lymph system acts like blood vessels only that instead of blood, they carry lymph. Just like certain organs as associated with the circulatory system like heart, the lymph system has such organs like the spleen and thymus.
Explanation:
When blood passes through capillaries, the blood pressure causes the blood plasma to filter through the capillary walls. This fluid then gets into the extracellular spaces of the cells and tissues and nourishes the cells. This fluid in which the cells ‘bath’ in is called interstitial fluid. Excess interstitial fluid flows back through the lymphatic systems and back to the blood through the subclavian veins of the thoracic duct.
The lymph system has several functions. It is responsible for the removal of foreign material like bacteria because the lymph nodes have 'meshwork' that ‘sieves’ the lymph fluid and immune cells destroy bacteria and viruses.

Answer:
if chloroplast is one of the answers then that's the answer.
Explanation:
so I am going with chloroplast.
Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.
Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.
A: In a lab a scientist measures the height of roses that received different fertilizers.
An experiment must include variables. The other three are just measurements, but since the scientist is varying the types of fertilizers used, this better describes an experiment. It is also done in a controlled environment (in a lab) which helps to eliminate other uncertainties.
