The answer is A, Genetic diversity in the new insect population will be lower due to the founder effect
During gas exchange, the cell membrane of a single-celled organism has the same function as the respiratory system in humans. The respiratory system is a biological system which is composed of specific organs and structures such as nose, pharynx, larynx, trachea, bronchi and lungs that are used for gas exchange in humans. The primary function of the respiratory system is to transport oxygen into the body and to breathe out carbon dioxide, which is a waste product of cellular function
Answer:
PFK: cytoplasm
insulin: ER--> Golgi--> outside cell
Explanation:
As described in the question, the enzyme phosphofructokinase (PFK) functions is a cells cytoplasm. Enzymes are proteins and proteins are made in the ribosomes of a cell. As ribosomes are present in the cytoplasm, hence PFK once made in the ribosomes will be released into the cytoplasm.
As for insulin, it will be made in the ribosomes. from there, it will move to the Endoplasmic Reticulum for packaging. Then to the Golgi complex for modifications and further packaging. Only after these stages, it will be ready to move out from where it is produces to areas where it has to be used.
Answer:
1. Reducing
2. External
Explanation:
The external urinary sphincter, also called as external urethral sphincter consists of skeletal muscles. During micturition reflex, the micturition center present in the brain serves to inhibit the somatic motor neurons by reducing their action potential. These somatic motor neurons innervate in the external urinary sphincter.
Inhibition of somatic motor neurons of the external urinary sphincter results in relaxation of the sphincter to facilitate the act of urination.
Answer:
Internal receptor: Internal receptors present on the cytoplasm, and also known as cytoplasmic or intracellular receptor. These Internal receptors respond to hydrophobic ligand molecules which can travel across the plasma membrane. These receptors can influence (directly) the gene expression means how much a specific protein is produced from a gene without having to pass the signal on the other receptor.
Cell-surface receptor: cell-surface receptor is present on the cell membrane is known as trans-membrane receptors. This trans-membrane receptor binds to external ligand molecules which cannot travel across the cell membrane. They are also called cell-specific proteins because they are specific to individual cell type. The cell-surface receptor has 3 main components:
1) External ligand-binding domain.
2) Hydrophobic membrane-spanning region.
3) Intracellular domain.
