natural selection vs artificial
Answer:
Please read the explenation for I must go into detail to explain this.
Explanation:
So before I answer your question, I am going to explain what the two things are.
Natural selection:
Natural selection is the evolution of traits in a species due to changes in genetics that is mainly caused by enviormental problems and changes.
If this is a bit confusing, here is an example:
Lets say that a Mandarin beatroot lizard is being killed off by the Mandarin carrot bird because all the trees in the area have turned yellow. 100 years from the time this happened, the Mandarin beatroot lizard that's population was 85% red and 15% yellow is now 90% yellow and only 10% red.
This is because of natural selection. THe Mandarin carrot bird was killing a large portion of the red population. The yellow population was killed only occasionaly. When the Madarin beatroot lizard went to breed, there were more yellow lizards breeding than red lizards. If you know how genetics work, then you know that in simple terms, this means more lizards will be yellow in the next genetration.
Slowl;y as the generations passed, more and more yellow lizards were bred and born. 100 years later, over generations and generations, the population was almost coimpeltly yellow.
Artifical selection:
Artifical selection is where the human race selects a species and bred specific organisms of that species so that the specific trait being bred for is more evident in the species.
Again, if this is confusing, here is an example:
The lab NV-110 was taking bearlybubble wolves with shorter noses and breeding them together. After 30 years, and many generations, the bearlybubble wolves had noses that were half a inch shorter than the orginal bearlybubble wolves. When the new wolves were let into the forest they had been taken from, half of the died in the first week due to starvation.
The humans took specific traits in a species and bred them together, this process was repeated over 30 years. The specific trait of the new generation of orgniasms has been changed, but this change affected the orgnaisms survive, and was dentrimental to the species.
So now knowing the two things, what do you think the difference is? Think about ti for a minute before reading more.
The difference betweent the two types of selection is:
Artifical selection can harm or possibly nuetral for the organism, wheareas natural selection will be helpful or nuteral to the organism.Artifical selection involves humans, wheareas naturals election does not,Artifical selection does not need any specific change in the enviorment or world to happen, wheareas natural selection does.Artifical selection is usally quicker than natural selction for artificial selection is purposful breeding, whereas natural selection is by-chance breeding.I hope this make sense to you, I can try to make this simpler or more detailed if you want me to. ;)

Preparing Informative Presentations
There are a variety of reasons a person presents a speech. Perhaps the most common reason is to present timely or useful information to an audience.
Such speeches are called expository speeches, and they rely on the effective transfer of information to listeners. An expository speech could be a definition speech, which explains an object, person, or event. It could also be a demonstration speech, which explains to the audience how to complete a process or task. A successful informative presentation depends on a few key steps that will help you prepare, inform, engage, and educate.
Based on the tips in the article, come up with a topic of your own that would make an interesting demonstration speech?

D. It goes through incomplete metamorphosis.
Answer:
D. It goes through incomplete metamorphosis.
Explanation:
Damselflies do not hide away inside a pupa to transform into their adult form. Instead, they shed their skin several times as they grow, changing shape a little each time. This process is called incomplete metamorphosis.
You are concerned with surveying the protozoa in the arboretum soil. While most commonly thought to live exclusively in aquatic environments, protozoa can play an important role in the nutrient cycling that takes place in soil. In addition, protozoa can help maintain the proper balance of bacterial populations within soil, as bacteria are a primary source of food for protozoa. Protozoa are extremely diverse. However, there are three characteristics common to all organisms called protozoa. What are these three characteristics
Answer:
eukaryotic, unicellular, without a cell wall
Explanation:
Protozoans are single-celled eukaryotes that generally move through cilia, flagella, or amoeboid motion. After their discovery, protozoans were considered as single-cell animals due to their animal behavior (including predation and motility), and because they don't have a cell wall, as observed in algae and plants. Some examples of protozoans include Paramecium, Amoeba, and Trypanosoma. Nowadays, the term 'protozoans' is still used to describe unicellular eukaryotic organisms from the Protista kingdom that are heterotrophs, i.e., unicellular microorganisms that acquire energy and nutrients from other organic sources, especially plant and animal matter.

Recall in class the example of incorporating heavy or light nitrogen labels into DNA to investigate how DNA is replicated. Imagine if, instead of labeling DNA, the experiment used heavy labeled RNA bases. What would be the outcome if you examined the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases?
Answer: You would not notice any difference or any labeled base, because RNA is not used to make DNA.
Explanation:
DNA is a molecule that contains the genetic information in all living things. The molecule consists of two strands that wind around each other to form a double helix structure where the strands are joined by hydrogen bonds. It is a nucleotide polymer where each nucleotide consists of a sugar called deoxyribose, a nitrogenous base (which can be adenine, thymine, cytosine or guanine) and a phosphate group (derived from phosphoric acid). What distinguishes one polynucleotide from another, is the nitrogenous base and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information.
Consider that DNA replication is semi-conservative, which means that each strand of the DNA double helix functions as a template for the synthesis of a new complementary strand. This process leads from one starting molecule to two "daughter" molecules, in which each new double helix contains one new and one old strand. Then, if nitrogen tags are incorporated into the DNA, they will register on the old strand of the new DNA molecule.
On the other hand, RNA (ribonucleic acid) is a molecule similar to DNA but has only one strand and consists of a sugar (ribose) and alternating phosphate groups. Attached to each sugar is one of the four bases adenine, uracil, cytosine or guanine. The process of RNA synthesis, called transcription, consists of making a complementary copy of a piece of DNA. During this process, an enzyme called ARN polymerase, adds nucleotides that are complementary to the DNA strand. Then, this new RNA strand has new nucleotides. Thereby, if you examine the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases, you would not notice any difference or any labeled base, because RNA is not used to make DNA.
