Your best answer would be B
Answer:
The correct answer would be karyotype of an individual.
Karyotype is the diagrammatic representation of the number and appearance of the chromosomes of an organism.
It determines the count of the chromosomes, their length, banding patterns, position of centromeres, difference between the sex chromosomes and other physical characteristics if present.
It helps in determining the presence of any chromosomal abnormalities in an organism.
For example, Turner syndrome (45, XO), Klinfelter syndrome (47, XXY), Down syndrome (trisomy of chromosome 21) et cetera .
pathogenic bacteria
anaerobic bacteria
rickettsia
pathogenic bacteria causes tetanus
The correct answer is 2. Pathogenic Bacteria
The endomembrane system consists of the nuclear envelope, ER, Golgi apparatus, lysosomes, vesicles, and plasma membrane. They collaborate to transport, package, and alter proteins and lipids. Components like mitochondria or chloroplasts are not part of the endomembrane system.
The endomembrane system in eukaryotic cells is composed of the nuclear envelope, the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vesicles, and the plasma membrane. These cellular components work together to perform several functions. Notably, they modify, package, tag, and transport proteins and lipids that form the membranes.
Starting with the nuclear envelope, it protects the contents of the nucleus by separating it from the cytoplasm. The endoplasmic reticulum synthesizes proteins and lipids. Golgi apparatus serves to further modify, sort, and package these proteins and lipids for transportation. lysosomes are involved in breaking down waste materials and cellular debris in the cell. Vesicles transport molecules around the cell. Finally, the plasma membrane controls the movement of substances in and out of the cell.
The endomembrane system does not include organelles like mitochondria or chloroplasts, as their membranes are not part of this system.

Answer:
A decrease in stability among populations
Explanation: if several species of carnivores are taken away from an ecosystem, there will be an instability among populations. Some of the factors that might cause the decrease in stability are that there would be an over population of the prey animal that would not be eaten by the carnivores and that the plant life would be in danger because of the over population of hervibores.
Cell membrane (plasma membrane) acts as a selective barrier, regulating the traffic of materials into and out of the cell.
The cell membrane, also known as the plasma membrane, is a crucial component of all living cells. It serves as a selective barrier that controls the movement of substances into and out of the cell. This selective permeability is essential for maintaining the cell's internal environment and regulating the exchange of nutrients, gases, and waste products. The cell membrane consists of a lipid bilayer embedded with proteins, and its hydrophobic interior prevents the passage of most polar molecules.
To facilitate the transport of specific substances, the cell membrane contains various proteins, including transport proteins, receptor proteins, and enzymes. These proteins help regulate the flow of ions, nutrients, and signaling molecules across the membrane. Overall, the cell membrane is a vital structure that ensures the cell's survival and functionality by controlling its interactions with the external environment.

The cell membrane acts as a selective barrier, regulating the traffic of materials into and out of the cell.
The structure that acts as a selective barrier, regulating the traffic of materials into and out of the cell is the cell membrane or plasma membrane.
The cell membrane is composed of a phospholipid bilayer with embedded proteins that control the movement of substances in and out of the cell. It selectively allows certain molecules to pass through while keeping others out, maintaining homeostasis within the cell.
For example, the cell membrane regulates the entry of nutrients and gases into the cell, as well as the removal of waste products and excess substances. It ensures that the cell maintains the appropriate balance of substances for proper functioning.
