Answer:
2. ER protein
4. insulin
6. lysosomal enzyme
Explanation:
Ribosomes serve as the cellular organelles responsible for synthesizing proteins since they create the necessary environment and machinery for this process.
Ribosomes can exist freely within the cytosol or be attached to the endoplasmic reticulum.
The proteins formed by free ribosomes are typically used within that same cell, such as DNA polymerase and ribosomal proteins, whereas proteins made by attached ribosomes are intended for transport throughout the cell, including insulin and lysosomal proteins.
Consequently, 2, 4, and 6 are correct.
Answer:
The respiratory system is comprised of specialized organs and structures for gas exchange in both animals and plants. The structure and function of this system differ significantly based on the organism's size, habitat, and evolutionary background. In terrestrial animals, the respiratory surfaces are typically the linings of the lungs. In mammals and reptiles, gas exchange occurs within millions of tiny air sacs known as alveoli, while birds have atria for this process. These tiny air sacs boast an extensive blood supply, ensuring air comes into close proximity with the bloodstream. They connect to the outer environment through airways or hollow tubes, with the trachea being the largest that divides in the chest into two primary bronchi. These then branch further into successively narrower secondary and tertiary bronchi, eventually leading to numerous smaller tubes called bronchioles. In birds, these are referred to as parabronchi. The air needs to be drawn into the alveoli or atria from the outside through the act of breathing, which involves respiratory muscles.
Explanation:
In a protein, amino acids are interconnected through peptide bonds, which results in the formation of a lengthy chain. The bonding occurs via a biochemical reaction that eliminates a water molecule as it connects the amino group of one amino acid to the carboxyl group of another nearby amino acid.<span />
Answer:
An XY or XY gamete combines with a standard gamete (X or Y)
Explanation:
Meiotic nondisjunction refers to the occurrence where chromosomes do not separate correctly during meiosis I or II. This process results in abnormal gametes, meaning gametes that may have excess or insufficient chromosomal content.
The fusion of these abnormal gametes created by nondisjunction with a typical gamete (either X or Y chromosome) leads to a condition known as ANEUPLOIDY, a chromosomal anomaly. In the instance of Calix, having an XXY configuration represents an ANEUPLOIDY state which may result from the fusion of either a XX gamete with a Y gamete, or an XY with an X. The XY or XX gametes are generated from nondisjunction.
Uncertain about what the question specifically requires, but potential appropriate responses could be inferior or perhaps even distal.
