Answer:
Multicellular organisms are made of more than one cell and are complex organisms.
They are visible to the naked eye.
They possess distinct organs and organ systems.
They are eukaryotes, i.e., they contain membrane-bound structures.
Their cells exhibit division of labor.
Their size increases with the number of cells in an organism
Explanation:
Answer:
The correct answer is - phase 2.
Explanation:
Erythropoiesis or the development of the erythrocytes is the process to which the development of the erythrocyte cells from the bone marrow to the mature RBC. The development of these cells involved the three phases.
During second phase involves the differentiation of the precursors of the three different type of erythrocytes that are polychromatophilic, proerythroblasts, and orthochromatic erythroblasts. It also includes building up the color of the hemoglobin that overwhelms the color of ribosomes that is blue color.
Thus, the correct answer is - phase 2.
They must find food
they must find shelter
The right answers are:
A-present in eukaryotic genomes ==> Both exons and introns
B-generally absent from bacterial genomes ==> Introns
C-part of the final mRNA strand ==> Exons
D-code for an amino acid sequence ==> Exons
E-removed from initial mRNA strand prior to translation ==> Introns
F-present in the DNA used as the template for transcription ==> Both exons and introns
In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.
