Answer: All living things are comprised of cells are in the case of unicellular organisms a cell. And what determines if something is living is whether are not it can reproduce without the assistance of a host organism. Some organelles all cells contain whether prokaryotic are eukaryotic are cell membranes Genetic material (DNA and forms of RNA) a cytoplasm and ribosomes. Obviously there are many more organelles but these are some shared by all cells whether prokaryotic, eukaryotic or plant a type of eukaryote.
The correct option is GOLGI VESICLES.
Golgi vesicle is a transporting structure that is found in the Golgi apparatus. The principal function of Golgi vesicle is to transport packaged proteins to their different locations within the cell.
Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
- Half-life of the radioactive atom (t1/2): 3,500 years
- Parent-daughter ratio ([A]/[A]₀): 1:127 (1/127)
Step 2: Calculate the rate constant
Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.
k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹
Step 3: Calculate the time elapsed (t)
For first-order kinetics, we will use the following expression.
ln ([A]/[A]₀) = -k × t
t = ln ([A]/[A]₀)/ (-k)
t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y
Answer;
Statocysts
Explanation;
-The small organs of equilibrium in scyphozoan jellyfishes are called statocysts, and these are borne in more complex sense organs called rhopalium.
The statocyst is a balance sensory receptor present in some aquatic invertebrates, including molluscs, bivalves, cnidarians,ctenophorans, echinoderms, cephalopods and crustaceans. These structures aid in orientation and balance during swimming in medusae and are located around the margin of the bell in Craspedacusta.
