Several natural products have been isolated from the flowering plant Sacrostemma acidum, which has been used in folk medicine as a cough suppressant.
Nаturаl products hаd been used by mаny cultures аnd trаditions from thousаnds of yeаrs for their bioаctive phаrmаcophores by modern phаrmаceuticаl compаnies. The potentiаl bioаctive phytocompounds such аs аlkаloids, flаvonoids, phenolic compounds, аnd steroids аre potentiаl source for drug discovery.
Sacrostemma acidum has been used in folk medicine as a cough suppressant. Acidum stem extrаct resulted in аn аrrest of spermаtogenesis without аny systemic side effect. Sperm motility аs well аs sperm density wаs reduced significаntly.

Answer:
B. adding a hydroxyl group C. adding a carboxyl group
Explanation:
Solubility in water is due to the polar interactions or the hydrogen bonding.
Methyl group and benzene ring are both polar and hydrophobic in nature and thus will not improve water solubility.
Increasing size of drug will make more insoluble as more size of the solute is being added.
Adding hydroxyl or carboxyl group can improve water solubility as both the groups are highly hydrophilic and polar. These groups can form hydrogen bond with the water molecules and make drug more soluble in the water.
political map
population map
relief map
The correct answer is (b) political map
The explanation:
when a political map: is different than other types of maps because it focuses on government or administrative boundaries rather than geographical or physical features. Instead of showing viewers what exists in the land, it shows those imaginary lines that serve to separate countries, states, territories, and cities. These maps generally include larger bodies of water, such as oceans, rivers, and lakes, as landmarks.
It was made by man not natural like the others maps.
so this is the correct answer.
A political map is the best tool to locate the boundaries between countries, providing distinct and accurate depiction of governmental boundaries.
The best tool to use to locate the boundaries between countries is a political map. Political maps are designed to show governmental boundaries of countries, states, and counties.
They also indicate the location of major cities, and they usually include significant bodies of water.
Unlike other types of maps like interrupted area maps, population maps, or relief maps, a political map focuses specifically on the delineation of imaginary lines separating different political entities, making it the ideal tool for identifying country boundaries.

B) They both are made of different kinds of particles.
C) They both look speckled or chunky.
D) They both look uniform (the same) throughout.
D) They both look uniform (the same) throughout.
Pure substance can be any element or compound and is formed from one type of atom/molecule only
Meanwhile, the solution is included in a mixture consisting of 2 or more pure substance
Pure substance can be formed through a chemical process while the mixture is through a physical process
Mixture can be separated by physical processes into components of pure substance while pure substance cannot
The mixture itself consists of a homogeneous and heterogeneous solution
The mixture can be divided into a homogeneous mixture if the composition/ratio of each substance in the mixture is the same and a heterogeneous mixture if the ratio of the composition of the substances is not the same (can be varied) in each place.
Mixtures can also be divided into solutions, suspensions, and colloids based mainly on the size of the particles
Homogeneous mixture = Solution
Heterogeneous mixture = suspension, and
The mixture is located between suspension and solution = Colloid
(2) absorb energy as they move to higher energy states
(3) release energy as they move to lower energy states
(4) release energy as they move to higher energy states
The light emitted from a flame is produced when electrons in an excited state absorb energy as they move to higher energy states. Thus option 2 is correct.
Energy level diagram is defined as a graphical illustration of the energies of an atom's or molecule's various orbitals.
The energy level diagram is typically shown as a sequence of horizontal lines, with each line representing an orbital.
It can also be defined as an electron shell, or energy level, can be visualized as an orbit of electrons surrounding an atom's nucleus.
Electrons absorb energy and move from ground state to exited state, and come back to original state by releasing energy.
Thus, the light emitted from a flame is produced when electrons in an excited state absorb energy as they move to higher energy states. Thus option 2 is correct.
