2. What is the main role of binary fission in prokaryotic cells? (1 point)to produce antibiotic-resistant genes
to transfer genetic materials from one cell to another
to fuse two cells together
to produce identical daughter cells
Answers
Answer:
To produce 2 identical daughter cells!
Explanation:
Binary Fission is a type of asexual reproduction in prokaryotic cells. Binary fission is done to transfer the DNA into the identical daughter cells. Binary means two and Fission means breakdown, so binary fission means breakdown into 2 identical daughter cells. The organism that reproduce this way are
- Amoeba
- Black-worms
- Hydras

Explanation:
Constructive forces are the forces that add new landmass on earth. They are typically formed by events such as volcanic eruptions, sediment deposition, and distortion in the crust.
The Hawaiian volcanic islands were formed due to the subduction of the Pacific plate under the NorthAmerican plate.
A dome generally forms when the magma rises up towards the surface. This hot magma lifts the land area, and subsequently with time, the magma cools and solidifies before eruption, giving rise to the formation of domes.
Beaches are formed due to the continuous erosion of the coastal rocks by the sea waves. Waves also carry sediments from the oceans to the coastal beach but it mainly erodes the rocks and sediment particles that are present on the beach area.
When sediment particles are carried by the rivers and streams and are deposited at the mouth of the river, then a delta is formed.
When an oceanic plate collides with a continental plate, then the denser oceanic plate gets subducted beneath the continental plate and forms a region of subduction where at great depth partial melting of the subducting plate takes place.
Along the mid-oceanic ridge, new crusts are added because the hot magma comes out to the surface and solidifies. This are rocks that are basaltic in nature.

Identify antigen and produce antibodies.
Explanation:
Lymphocytes:
- are the types of white blood cells and the main part of lymphatic system.
They consist of 2 types of WBCs.
1) T-lymphocytes:
- There are many types of T-lymphocytes but the main type are the cytotoxic t-cells.
- T-cell receptors also identify antigens.
2) B-lymphocytes:
- They produce antibodies.

experiments need a hypothesis (this would correspond to "what they already believe") which has to be a specific proposal, not a question (e.g. turtles reproduce sexually)
their experiments proove (or, better said: test!) whether "what they already believe" is true.
