Answer:
This question is incomplete as the term to match with the level of organisation is not included, the terms are;
circulatory system
cardiac muscle
heart
human body
The ANSWER is:
Organ = heart
Organ system = circulatory system
Tissue: cardiac muscle
Explanation:
The level of organization of multicellular organisms is made up of cell, tissue, organ, organ system and eventually organism.
- The tissue is composed of several cell, which are basic units of any living organism. Cells that perform similar function come together to form the tissue. Example is the CARDIAC MUSCLE in this question, which is a muscular tissue made up of cells called myocardiocytes.
- Organs are structures formed as a result of collection of tissues with similar function. For example, the HEART is a circulatory organ made up of cardiac tissues, connective tissues etc.
- Organ systems is made up of organs that perform the same function in a living organism. In the case of the CIRCULATORY SYSTEM, it is made up of organs such as heart, blood vessels, lungs etc.
The right answer is Haploid cells join to form an organism that has a complete set of chromosomes.
Meiosis makes it possible to pass from a cell to 2n chromosomes to 4 cells with n chromosomes, thus ensuring the passage from the diploid phase to the haploid phase.
So from the fertilization phase to the meiosis phase, the cells will be diploid (2n chromosomes). From the meiosis phase to the fertilization phase, it is the haploid phase (n chromosome).
Answer: Option C) AGU
Explanation:
AGU and AGC are the two codons that code for the amino acid, Serine. These codons are made of three nucleotides, thus they have a triplet nature.
AGU that code for serine is made of Adenine, Guanine and Uracil joined together, carried on the messenger RNA to be added to the growing polypeptide chain.
