Answer:
The theory of evolution by natural selection
Explanation:
Nowadays, it is widely accepted that chimpanzees are primates closest related to us. Darwin's postulated "The theory of evolution by natural selection", in the book "On the Origin of Species" in 1859. It is a theory that explains how species evolve over successive generations by gradual changes and the selection of the most adaptive phenotypes. Anatomical, fossil, and genetic evidence support the idea of an evolutionary link as Darwin predicted between hominids (humans) and other primates.
In regard to genetic evidence, whole-genome sequence analyses have shown that humans and chimpanzees share about 98% of sequence homology. Moreover, according to the phylogenetic tree, both species evolved from one common ancestor that was present approximately 4 million years ago.
In regard to anatomical and fossil evidence, it has been discovered that the chimp brain has a similar size to human extinct relatives, and thereby also supporting an evolutionary link between both species.
The picture doesn't mention mating or nesting - there is not a single mention of those. Therefore we cannot use answers 2) and 4), since we know nothing about them.
The same actually holds for 3) - while there is a mention of the beaks and you can infer the beak size, there is no connection between the beak size and mating activity.
so the correct answer is 1) -the type of beak is matched with the food.
The structure that is labelled C would be a protein, a specific type of protein that helps in regulating the transport of substances in and out of the cell.
Answer:
Farming enabled people to grow all the food they needed in one place, with a much smaller group of people. This led to massive population growth, creating cities and trade.
Hope this helped a little <3
During active transport proteins powered by ATP move substances up a concentration gradient. During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.
