B.) Resources must be limited in the ecosystem
There are four basic types of camouflage:
Concealing Coloration- when an animal hides against a background of the same color (polar bears, snowshoe hare, and arctic fox with white fur living in the Arctic).
Disruptive Coloration- stripes, spots, or other patterns an animal uses to make it hard for predators to their body outline (zebras, leopards, tigers living in grasses).
Disguise- like concealing coloration but the animal blends in with their surrounding by shape and texture rather than color (lizards with bumpy skin, octopus mimicking coral, walking stick insect).
Mimicry- animals mimic the characteristics of unappetizing animals (insect mimicking a poisonous bug, caterpillar designed to look like a snake).
Answer:
"One gene, one enzyme" hypothesis says that one gene encodes for one protein which performs a specific function in the living organisms. This study, published in 1941, was one of the most influential studies of the age and for that, Beadle and Tatus also received Nobel Prize.
However, in recent years, it has been well studied that many enzymes are encoded by more than one gene (or cluster of genes). There are some enzymes that are produced by a single gene; nevertheless, it has been concluded that the hypothesis is not completely true. But it is also important to say that this study set the baseline for the study of many biochemical processes in living organisms.
<span>Natural selection is when species learn to adapt to
their environment. They could (1) differential reproduction, that is, not all
organisms are able to reproduce to their fullest capacity because nature cannot
simply sustain it and (2) acquire genes, that is heredity. Certain
characteristics of organisms tend to survive if it continues to strive. If it
survives, this trait is passed down to the next generations forgetting the
other traits but only the one who could survive the environment. Therefore it
is true that <span>natural
selection is when ‘organisms inherit advantageous traits, and tend to reproduce
more successfully than other organisms’. One best example is the extinction of
other animals and some with the same species retains.</span></span>
Answer;
C. Unique three-dimensional shape of the fully folded polypeptide
The tertiary structure of a protein is the unique three-dimensional shape of the fully folded polypeptide
Explanation;
A protein is a functional biological molecule that is made up of one or more polypeptides that are folded/coiled into a specific structure.
-As the secondary structure becomes established due to the primary structure, a polypeptide folds and refolds upon itself to assume a complex three-dimensional shape called the protein tertiary structure. Tertiary structure results from the interactions between the side chains (R groups) of the various amino acids.
