Answer:
Roots absorb nutrients and water from the soil, as well as keep the plant attached to the ground. Some plants also use the roots, to parasite other plants (ie, Mistletoe) or reproduction (Potatoes).
Stems, transport water and nutried to the plants up reaches, sometimes they are important for protection, as they are covered in thorns or toxins.
Branches sort of form the same function as stems, only they branch out from the stem.
Leaves, are where the plant conducts its metabolic photosynthetic processes. Sometimes the leaves are also important for protection (the thorns of cacti are actually leaves).
Flower, are useful for reporduction, giving out pollen and when combined with other pollen are turned into fruits.
Fruits are the protective object of the seed, and provide nutrition for the seed, a means of seed dispersion, and lastly protection from outside forces.
Explanation:
Among the given choices, an example of homeostasis is the first choice, which is when a cactus <span>stores water during wet periods, allowing it to live through dry periods
</span>
Homeostasis refers to the ability or tendency of a system (i.e. physiological) to maintain a stable internal environment even when environmental or external conditions may change or vary.
<span>
The other examples given in the choices do not reflect equilibrium because they depict the inability of the body or organisms to maintain a stable internal environment because of failure to cope with changes in the external environment (too much heat, cold, and water loss).

Answer -
RNA - Stands for (ribonucleic acid)
The difference between RNA and DNA is difference in sugar and the make up of the back bone. For example in DNA it has deoxyribose (hint) why its called deoxyribonucleic which is one less O2 then ribose.
In addition they have different back bones in which are in
DNA its adenine, guanine, cytosine, thymine.
RNA its adenine, guanine, cytosine, uracil.
Can make a big difference trust me with those compounds.
Reproduction, growth, renewal and repair are all reasons for cell division in multicellular organisms.
Cell division is a process that allows a parent cell divides into more smaller cells. It is classified as mitosis and meiosis. Mitosis produces diploid cells that will be used for growth or repairing tissue. Meiosis will produce gamete that has a role in reproduction.
Explanation:
Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus. However, antiviral medications and vaccines are specific for viruses.
