Answer:
C. Darwin performed an experiment that supported his hypothesis.
Explanation:
Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then <em>discovered</em>) to emerge is proof of such.
Answer:
The correct answers would be maintain chromosome number through generations and cause genetic variations by recombination.
In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.
It helps in the formation of gametes in sexually reproducing organisms.
These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.
In absence of meiosis, the chromosomal number would have doubled after each generation.
In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.
During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.
Answer:
I'm not great at science and especially not biology but
Explanation:
the energy is transformed by the nucleus inside the cell and energy is held there it will soon release motonchdria holds the blood cell and energy will be transformed somewhat that way sorry if it doesnt help
Most of the digestion and absorption in the small intestine is accomplished by the duodenum; the longest portion of the small intestine is the ileum.
<h3>What is Digestion and Absorption?</h3>
Digestion stands for the complex function of turning the food you eat into nutrients, which the body utilizes for energy, growth, and cell repair required to survive. The digestion process also concerns creating waste to be eliminated.
Digestion stands for the breakdown of extensive insoluble food molecules into small water-soluble food molecules so that they can be immersed in the watery blood plasma. In particular organisms, these smaller substances exist absorbed via the small intestine into the bloodstream.
Absorption exists as a physical or chemical phenomenon or a procedure in which atoms, molecules, or ions penetrate some bulk phase – liquid or solid material. This is a separate process from adsorption since molecules undergoing absorption stand taken up by the volume, not by the surface.

<span>Fires can help eliminate the roots and shoots of invasive plants and stimulate growth of native species. Controlled fires can eliminate infected plants and enrich the soil. Controlled fires can also eliminate overcrowding of plants or trees. It can eliminate diseased or damaged plants as well.</span>
