During Meiosis 1 in Prophase 1 crossing over occurs. The two chromosomes switch part of their genetic information. Also independent assortment occurs during meiosis which is the formation of random combinations of chromosomes in meiosis and of genes on different pairs of homologous chromosomes.
Answer:
C)
Explanation:
Bacteria are prokaryotic, which means they (generally) don't have organelles or a nuclear envelope around their nucleus. They have ester linkages in the phospholipids in their cell membranes, while archea, which are also prokaryotic, have ether linkages. Ether linkages are more chemically stable than ester linkages, and since archea live in extreme environments this is helpful.
Bacteria are not multicellular and do not have organelles (complex cellular structures) besides ribosomes.
The block shown above is a cube of halite. Each side measures 3 cm. Then the volume of the cube of halite is 27 cm³.
<u>Explanation:</u>
Step 1:
All the sides of the cubes are equal.
Step 2:
Given,
a= 3 cm
Step 3:
Volume of the cube = a³
= 3 × 3 × 3
= 27 cm³
Hence, The volume of the cube is 27 cm³
