Ribosomes and mitochondria are two types of organelles.
Answer:
<em>The correct option is C) the species contained large amounts of genetic variation.</em>
Explanation:
Genetic variations allow more diversity to occur in a population of species. The genetic variations among species of a population tend to make the population more stronger. The genetic variations allowed the wild plant <em>Brassica oleracea</em> to separate into many varieties such as cabbage, Brussels sprouts, kohlrabi, kale, broccoli and cauliflower.
Artificial selection is the method through which organisms with favourable characteristics are bred together so that offsprings with better characteristics can be produced.
Answer:
A.
Explanation:
The lower it goes, the older it gets!
Among the geothermal features found in Yellowstone<span> are numerous </span>geysers<span>, </span>hot springs<span>, bubbling mud pots, and </span>hot spring<span> terraces. </span>Hot springs<span> are pools of </span>hot<span>water that have seeped to the Earth's surface to </span>form<span> small ponds.</span>
<span>According to the nebular theory stars are formed in which sequence:
a. Interstellar clouds - "nebula" is a Latin word which means clouds. These clouds start to form and are composed of gases like hydrogen and helium.
b.Clumps - as the gases start to form and come together they form clumps of gases that are highly concentrated and they start to grow.
c. Gravitational forces - when clumps have grown into big sizes the gravitational forces that are found within it increases and are converted into kinetic energy of fast-moving particles that continuously bump into each other and create or generate heat.
</span><span>
d. Nuclear fission - as the clumps keep on colliding and creating heat (18 million degrees Fahrenheit), nuclear fission begins.
e. Outward pressure from the nuclear fission prevents the collapse of the gases, stabilizing the gases eventually creating a star. </span>
