V final = (Mass x V initial) + (Mass x V initial) /m + m
V = (0.04 x 300) + ( 0.5 x 0 ) / 0.04 + 0.5
V = 22.2 m/s
A newly synthesized protein destined for secretion from a eukaryotic cell will generally Rough ER - Golgi- transport vesicle - plasma membrane.

What is eukaryotic cell?</h3>
- Eukaryotes are organisms having cells that contain a nuclear envelope around their nucleus.
- They are a member of the Eukaryote class of organisms.
- One of the three domains of life is the eukaryotic domain.
- The other two are the bacterial and archaeal domains.
- Organisms called eukaryotes have nuclei and membrane-bound organelles in their cells.
- Eukaryotic creatures come in a great variety, including most algae, all animals, plants, fungus, and protists.
- Eukaryotes are multicellular or unicellular organisms.
- The primary distinction between these two categories of organisms is that eukaryotic cells have a membrane-bound nucleus while prokaryotic cells have not.
- The nuclei of eukaryotes house their genetic material.

The answer is c. oxygen.
Cellular respiration includes glycolysis, link reaction, Krebs cycle, and electron transport chain (ETC), in that order. The main function of ETC is a production of ATP. In this series of oxidation-reduction reactions, electrons from the previous stages of cellular respiration are taken and transported to the oxygen which is the final acceptor of electrons. As the result, water and ATP are produced.
Answer: a. cervical enlargement.
Explanation:
Cervical enlargement corresponds to the enlargement of the spinal cord. The spinal cord is the origin of the spinal nerves that contribute to an important task of supplying blood to the upper limbs.
The cervical enlargement results in an increase in the volume of the motor cells in the ventral part inside the grey matter. The motor neurons which are sited posteriorly supply to the upper limbs. Those which supply to the distal muscles are situated further posteriorly.
ANSWER : have a specific shape related to their specific function
