Answer:
The following scientists have performed different experiments that were helpful in providing evidence that DNA is the genetic material. The summarize experiments are as follows-
1. Fredrick Griffith- the experiment was an experiment performed in 1928. It was one of the experiments that exhibit that bacteria can acquire through the process of transformation.
2 Oswald Avery, Maclyn McCarty, and Colin MacLeod: this experiment exhibited that DNA can transform the cell properties, and clarifying the chemical properties of the genes.
3. Alfred Hershey and Martha Chase: They determined that even the bacteriophage has a protective coat around it but the DNA that is present inside is the genetic material that has the ability to produce the progeny inside a bacterium.
4. Erwin Chargaff: He proposed tow rules which were named after him as chargaff rules. This tells that natural DNA the number of cytosines is equal to the number of guanine units and adenine to Thymine units.
Taphonomists would probably conclude that hominins had scavenged meat from an animal carcass, they did not kill if fossil animal bones; did not contain stone cut marks, which are easily distinguishable from tooth marks.
Some characteristics that have distinguished hominins from other primates, living and extinct are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use, and in some cases communication through language.<span />
One of my passions is keeping up with creationist (and I include Intelligent Design here) attempts to change what science is. They wish to supplant the reason and evidence that is the basis for good science with faith instead – specifically their faith.
Sometimes, actually often, it can become discouraging looking at how many battles must be fought to ensure our schools continue to teach good science; listening to all the politicians expressing their ignorance of science by expressing doubts about evolution; and seeing all the letters and forum responses from those who let their religion totally blind their ability to reason and fairly judge evidence.
For example, consider these quotes from various prominent politicians:
“There are clear indications from our people who have amazing intellectual capability that this didn’t happen by accident and a creator put this in place,”
“Now, what was his time frame and how did he create the earth that we know? I’m not going to tell you that I’ve got the answers to that,” Perry said. “I believe that we were created by this all-powerful supreme being and how we got to today versus what we look like thousands of years ago, I think there’s enough holes in the theory of evolution to, you know, say there are some holes in that theory.” Governor and Presidential candidate Rick Perry
Answer:
Direct relationship.
Explanation:
There is direct relationship between the temperature of internal material and volcanic eruptions because the temperature of internal material causes the volcanic eruptions. The temperature of the internal material puts pressure on the rocky surface and the gases that releases from heating processes will cause pressure which leads to the eruption of the volcano so we can say that there is a direct relationship between temperature and eruption.
The correct answer is false and here is why:
Clear cutting refers to the cutting of trees, specifically all of the trees in one select area. Replanting is not done and this leads to deforestation.
Controlled burns have a completely different affect. They burn the under brush to help keep the soil rich with nutrients, plus they also help to prevent large crown fires that burn down whole forests from happening.
Clear cutting is a bad thing and controlled burns are a good limiter for a forest.
