Answer:
The theory of natural selection was proposed by Charles Darwin, which states the mechanism of biological evolution by explaining <u>adaptation and speciation.</u> There was five observation of the theory of natural selection.
1) The population produces more offspring than there are adults, in each generation.
2) The population does not continue to grow in size.
3) Food and many other resources are limited.
These three observations interfere that individuals compete for resources within a population.
4) Individuals within all populations vary.
5) Many variations are heritable.
He also assumed from these two observations that individuals inherit some characteristics that give a better chance of surviving and reproducing.
These observations and interpretations helped him to propose the theory of natural selection. The theory tells the <u>heritable characteristics in a population change over time</u> <u>become more adapted in generation after generations.</u>
This is false because rivers and oceans are two different things
Answer:
What is an allele.one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Explanation:
The common cuckoo does not make a nest of its own, and they do not bring up their own young. Instead, the female lays her eggs in the nests of other birds. Each female cuckoo specialises in just one host species, and lays camouflaged eggs in that bird's nest.
The group of choices is as follows:
Proteins' primary function is to provide energy to cells.
Lipids' unique 3D structure determines their function.
Nucleic acids are critical components of plant cell walls.
Carbohydrates include glucose, a critical molecule for cellular respiration
Answer:
The correct answer is - Carbohydrates include glucose, a critical molecule for cellular respiration
Explanation:
Macromolecules are the large molecules of nutrients that are made by the polymerization of monomers or smaller subunits and perform various cellular functions. These molecules are protein, carbohydrate and nucleic acids.
The biological function of these molecules is not limited but they have different primary functions and among the given group of choices the best function is carbohydrate perform cellular respiration to produce energy as its primary function to provide energy to cells.
