The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving
and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment? Mutations are always passed on to subsequent generations of the species
Mutations lead to genetic variation
Mutations are the cause of disease in the species
Mutations are not harmful when they occur in somatic cells of a species
Your answer is B) Mutations lead to genetic variation.
Think of it like this, when rays were first starting to develop, they probably started with only one kind, stingless. Somewhere down the line, the genes of the rays started to mutate and eventually, there were stingrays and stingless rays. Now at this point there are predators that frequently feast upon the rays, so which of the two rays are more likely to defend themselves, and get away to live long enough to reproduce and pass on their genes? The stingrays! The mutation that may have occurred millions of years ago, has determined which organisms were more fit for a changing environment.
The urinary system carries out essential bodily function that help to maintain the body.
Apart from the obvious function of excreting <span>nitrogenous wastes, it helps to maintain an acid-base </span>homeostasis, regulate electrolyte balance and even helps to control blood volume and pressure
The chart is a basic molecular design of multicellular organisms.
Atoms, molecules, cells, tissues, organs, organ systems are the building blocks of the human body which combine together on the basis of similar function or structure to achieve various body functions.
Atoms form chemical bonds with other atoms and form molecules.
Molecules combine together to form cells.
Cells are the basic functional and structural units of life.
Cells that perform similar functions combine together to form tissues.
Two or more kinds of tissues that perform similar functions combine to form organs.
Organs, in turn, form organ systems such as the respiratory or cardiovascular systems etc.
