Write a short informational paragraph explaining the role that DNA has in creating protein in your body.

jasenka [17]

DNA is found in the nucleus of a cell. Depending on the type of cell, different parts of the DNA are used (example; if it's an eye cell, the DNA will use the segment that is dedicated to the functions of the eye). When a protein is needed, the DNA will split and in a process called transcription, the DNA messages are copied onto mRNA. The mRNA then leaves the nucleus through nuclear pores, and then travels through the cytoplasm to locate ribosomes which will produce the proteins needed to express whatever trait it codes for.

What are the differences in their hard parts, distribution, reproduction among phytoplankton of cyanobacteria, diatom, coccolith

Margarita [4]

Answer:

Explanation:

DIFFERENCES BETWEEN HARD BODY PARTS.

•Cyanobacteria have calcified sheaths.

• Diatoms have hard but porous cell wall.

• Coccolithophores have hard body parts.

• Silicoflagellates skeleton is composed of opaline silica.

• Dinoflagellates do not have hard body parts

• Green algae - no hard body parts.

• Brown algae - no hard body parts.

DIFFERENCES BETWEEN DISTRIBUTION

• Cyanobacteria are found almost in every terrestrial habitat on planet.

• Diatoms are found in oceans, freshwater, soil and damp.

• Coccolithophores are exclusively marine.

• Silicoflagellates are found in marine environment.

• Dinoflagellates are both freshwater and marine.

• Green algae grow on objects that do not move such as substrate, rock.

• Brown algae - wide distribution from tropical to polar zones.

DIFFERENCES BETWEEN REPRODUCTION.

• Cyanobacteria - asexually by binary or multiple fission, fragmentation, spore formation.

• Diatom - asexually by cell division through mitosis.

• Coccolithophores - asexually by binary fission.

• Silicoflagellates - asexually

• Dinoflagellates - asexually

• Green algae - sexually or asexually by cell division, fragmentation, spore formation.

• Brown algae - sexually and asexually.

2. Identify the epithelial tissue that is most suited to each of the following functions. a. diffusion of gases across lung air

Delicious77 [7]

Answer:

e. secretion, absorption and chemical protection

Explanation:

Epithelial tissues is responsible for the protection of the skin, absorption of nutrients during digestion and secretion of waste materials. These tissues form covering to all body surfaces. They also perform a variety of other functions such as excretion of waste substances, filtration of air from dirt and particles and clean the air that is inhaled, diffusion, and sensory reception.
