Ribosome packages nutrients and sends itto different parts of the cell
Answer:Scientists have long believed that the 14 species of finches on the Galapagos Islands evolved from a single species of finch that migrated to the islands one to five million years ago (Lack, 1940).
Explanation:
Answer:
The correct option is <em><u>B. Eukarya only</u></em>
Explanation:
Bacteria can be described as prokaryotic organisms that do not possess a nucleus. Their genetic material is generally present in the cytoplasm of the cell in a region called nucleoid. Some extra genetic material is found in them in the form of plasmids. Hence, option D is not correct.
The domain, Archae, contains prokaryotes and they lack a nucleus. Hence, option A and C are not correct.
Eukaryotes are multicellular organisms which contain a nucleus and other membrane-bound organelles. Hence, option B is correct.
D.
Photosynthesis creates energy that the plant stores, and cellular respiration utilizes the energy.
Option (A) 100 ng on 7 chromosomes.
If a single, diploid G₂ nucleus in an ascus contains 400 nanograms (ng) of DNA, then a single ascospore nucleus of this species should contain 100 ng of DNA on 7 chromosomes.
<h3>
What is chromosome?</h3>
- A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code.
- Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.
- A chromosome's primary purpose is to transport genetic material from one generation to the next.
- Gene control, protein synthesis, and cellular replication are all functions of chromosomes. DNA may be precisely duplicated during these cell divisions thanks to chromosomes.
- Chromosomes come in four different types: metacentric, sub-metacentric, acrocentric, and telocentric.
