A variety of species of Galapagos finches evolved from one original species long ago through
the process of
A)
asexual reproduction
B)
ecological succession
natural selection
D)
selective breeding
Answer:
A. Asexual Reproduction
Explanation:
The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.
Galapagos finches can be called Darwin's finches are derived recently from the common ancestor. A variety of species of Galapagos finches evolved from one original species long ago through the process of natural selection.
What is natural selection?Natural selection is the process of changing and adapting in the environment of a given population.
There are four conditions needed for natural selection:
Reproduction.Heredity.Variation in the organism.Variation in individual characters.A variety of species of Galapagos finches evolved from one original species a long time ago by the process of natural selection.

Where is potential chemical energy stored?
In a closet
In the bonds between atoms
Between different molecules
Between the protons of an atom
Answer:
In the bonds between atoms
Explanation:
Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.
Mutations that create small differences in the DNA sequence , making different versions of the same genes, best account for
Answer:
cancer (a mutated gene)
Mutations that create small differences in the DNA sequence, making different versions of the same genes, best account for oncogene. These different versions of the same genes are called alleles.
What is mutation?A mutation is a change that takes place in the sequence of our DNA as a result of errors made during DNA replication or environmental influences like UV light and cigarette smoke.
Base substitutions, deletions, and insertions are the three different forms of DNA mutations. Depending on the situation or location, the impacts of mutation might be advantageous, detrimental, or neutral.
One or more genes can mutate to create genetic diseases. One such genetic illness brought on by a mutation in one or more genes is cystic fibrosis. Another illness brought on by a change in the genes that control the cell cycle is cancer.

Explanation:A) selecting and breeding the organisms for
specific traits
Genetic recombination, production of more offspring than can survive, and struggling with the challenges of the environment are all concepts associated with selective breeding.
What do you mean by selective breeding?Selective breeding entails selecting parents who possess particular traits to mate to produce offspring with more desirable traits. For thousands of years, humans have selectively bred a variety of plants and animals.
The reason for particular reproducing is to foster domesticated animals whose positive characteristics have solid heritable parts and can hence be engendered.
By selecting which typically animal or plant males and females will sexually reproduce and bear children together, selective breeding allows humans to selectively develop particular phenotypic traits.

What do you mean by food web?A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Another name for food web is consumer-resource system.
Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow. At the top of the system are the apex predators: animals who have no predators other than humans.
Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.

How does killing whales affect the food chain?
Whales play an important role in stabilizing the aquatic food chain and reproduction of other species.
As more whales are killed the food distribution in the ocean becomes destabilized and causes changes in the food supply of many other kinds of marine life.
Whales are vital to the food chain, stabilising food flow and maintaining a healthy ocean.
As such, the rapidly decreasing whale population will have major effects on the ocean's ecosystem.
Believe it or not, whale poop also serves quite an important purpose to the ecosystem.

Flatworms have a remarkable ability to generate a whole body from any small piece. This multi-headed worm will split apart and grow into several complete, separate individuals.
Offspring that are genetically identical to the parent are produced by reproduction.
Answer:
Small piece of its body.
asexual reproduction.
Explanation:
Flatworms is also reproduce by multiple fission. The body of flatworms splits into small pieces and each piece becomes a new individual. Asexual reproduction is a type of reproduction in which a new organism is formed from a single parent which is identical to that parent and no variation in size and shape of offspring. examples of asexual reproduction are binary fission, multiple fission, segmentation and budding.
