A molecule is a fundamental concept in chemistry that represents the smallest unit of a chemical compound that retains the properties of that compound. It's formed when two or more atoms come together and bond with each other.
Atoms are the basic building blocks of matter. They consist of a nucleus composed of protons and neutrons, surrounded by a cloud of electrons. Atoms can combine with each other through chemical bonds to form molecules. One of the most common types of chemical bonds is the covalent bond. In a covalent bond, atoms share electrons to achieve a more stable electron configuration.
In ionic bonding, atoms transfer electrons to each other, resulting in the formation of ions with opposite charges. These ions are attracted to each other, creating an ionic bond. The arrangement of atoms within a molecule is crucial to its properties and behavior. The type and arrangement of bonds determine the molecule's shape and how it interacts with other molecules.

Explanation:A special case of polar forces occurs in what is called the hydrogen bond. In many situations, when hydrogen forms a covalent bond with another atom , electrons move toward that atom, and the hydrogen acquires a slight positive charge. The hydrogen, in turn, attracts another atom, thereby forming a kind of bridge between the two.
i think
Answer;
Two different shell patterns are increasing in frequency, while the most common pattern is decreasing(CA).
The statement that is most likely true about the population is that two different shell patterns are increasing in frequency, while most common pattern is decreasing.
Explanation;
Disruptive selection involves changes in population genetics such that the extreme values of a trait are favored over the intermediate values.
Disruptive selection often drives speciation.
It may also occur when environmental changes favor individuals on either end of the phenotypic spectrum.
B) Flagella
C) Microtubules
D) Ribosomes
Answer:
The correct answer would be D) Ribosomes.
Ribosomes serve as the site of translation in prokaryotes as well as eukaryotes.
It produce proteins or polypeptide chains with the help of mRNA (messenger ribonucleic acid) and tRNA (transfer ribonucleic acid).
It gets attached or assembled near the start codon of the mRNA. mRNA provides the instruction from the DNA (deoxyribonucleic acid) to the ribosome in the form of codon sequence.
The codon sequence are then decoded with the help of tRNA which then adds specific amino acid to the growing polypeptide chain.
As soon as the ribosome reaches stop codon, it releases the mRNA and polypeptide chain.
The peptide chain then undergoes various post-translation changes to become a mature and functional protein.
pre-consumer waste
post-consumer waste
e-waste
rucksack
Answer:
Pre-consumer waste is the waste that is created in the process of making products.
Explanation:
Pre-consumer waste is that waste that is produced in the process of production and processing of products, without these have yet reached final consumers. That is, it is the waste generated as a result of production and not the use of a good.
B.Survival is done by the strongest.
C.All life comes from life.
D.Species evolve and become better adapted to their environment.
