Carbon atoms tend to form covalent bonds.
Covalent bonds involve the sharing of electrons between atoms, instead of losing or gaining electrons permanently like in ionic bonds.
This sharing provides a mutually stabilizing relationship between atoms, similar to how neighbors share resources.
The simplest organic molecule, methane, exemplifies this process. Carbon fills its valence shell by linking up with four hydrogen atoms, leading to the formation of methane.
This action is achievable via covalent bonds.
Molecules formed by covalent bonding are generally more stable and stronger than those formed via ionic bonding.
The bonds' strength comes as a result of the close sharing of pairs of electrons.
Therefore, it's accurate to say that carbon atoms, in general, tend to form covalent bonds.

The process of translation involves three main types of RNA, including mRNA, tRNA, and rRNA, working together to decode information from DNA and build proteins in the ribosomes.
During the process of translation, mRNA decodes information from the original DNA master plan to build proteins in the ribosomes. This process involves three key types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). The mRNA carries the genetic information copied from DNA in the form of a series of three-base code words, each of which specifies a particular amino acid.
The tRNA molecules act as adapter molecules, each able to carry a particular amino acid and recognise the appropriate codon in the mRNA. Through a series of steps, the tRNA molecules bind onto the mRNA and add their amino acid to the growing chain of amino acids that ultimately forms a functional protein.
Last but not least, the rRNA molecules come together with particular proteins to form a functional ribosome that facilitates the assembly of the amino acids into the new protein.

Answer:
This is an example of recessive epistasis.
Explanation:
Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.
Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is recessive, the interaction is known as "recessive epistasis".
Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.
In recessive epistasis, the proportion is 9:3:4.
Answer:
a keystone species
Explanation:
A keystone species is a species that plays a key role in the balance of the entire ecosystem. Some examples of keynote species that are critical for their ecosystems include sharks, African elephants, sea otters, etc. The most important feature that defines a keynote species is the fact that these species have a huge influence on the food web dynamics. Moreover, keystone species are also characterized by a low functional redundancy (ie., they cannot be replaced by other species within the ecosystem).
