The answer for this question is genus
Answer:
a. Nucleolus: The nucleolus refers to a composition, which develops with the assistance of the nucleolar organizer region present in the eukaryotes. It constitutes protein and ribosomal DNA and is a location where the generation of ribosomes takes place.
b. Centromere: The prime function of the centromere is to function as the point of attachment for sister chromatids and is a place where the attachment of chromosomes and spindle fibers takes place. The differentiation of centromere takes place at the time of mitosis and meiosis II, which helps in the distribution of chromosomal substances to the daughter cells.
c. Ribosome: The ribosome refers to the composition where different forms of RNAs, enzymes and other components help in the alignment of the primary sequence of a specific protein.
d. Chromatin: Chromatin constitutes the genetic information, which helps in sustaining hereditary information and generation of a phenotype.
e. Centriole: The centriole refers to a cytoplasmic composition, which via the help of spindle fibers assists in the migration of chromosomes at the time of meiosis and mitosis, mainly in the animal cells.
f. Mitochondria: The mitochondrion refers to a membrane-bound composition situated in the eukaryotic cytoplasm. It is the place where the production of huge amounts of ATP takes place via the process of oxidative phosphorylation.
Answer:
The respiratory system is necessary for an organism's body to live because it introduces oxygen-rich air, which is needed to perform vital functions, while at the same time promoting the elimination of carbon dioxide.
Explanation:
Oxygen (O₂) is necessary for life because it participates in the process of cellular respiration, a mechanism that allows the oxidation of glucose to form energy in the form of ATP.
The respiratory system is made up of a set of organs that carry air into the body and facilitate gas exchange, i.e. the entry of O₂ into the blood and the elimination of potentially harmful carbon dioxide (CO₂).
This exchange of gases occurs in structures called pulmonary alveoli, whose surface is located in relation to the pulmonary capillary vessels.
- The entry of air into the lungs brings O₂ to the alveoli, which will diffuse into the pulmonary capillary for the process of hematosis or oxygenation of the blood.
- CO₂, a product of metabolism, leaves the capillary to the alveoli, to join the air that will be expelled during expiration.
Both O₂ and CO₂ require a transport molecule in the blood, red blood cell hemoglobin, which binds the gases and allows them to be transported to and from the tissues.

Answer:
The given statements are True.
Explanation:
The particle of the matter through which a wave move or travels is called medium. The mechanical waves can be distinguished into three types on the basis of the movement of the medium when the energy of the mechanical wave passes through, are: transverse, longitudinal, and surface waves
A transverse wave: perpendicular to the direction that the wave
A longitudinal wave: parallel to the direction that the wave
