In 2000, Bob Harmon discovered the best-preserved Tyrannosaurus Rex skeleton ever found. The fossilized dinosaur was sticking out of the wall of a canyon in Montana. Many scientists were eager to study the fossils. Dr. Mary Schweitzer got one of the leg bones to analyze. Dr. Schweitzer's assistant dissolved the bones in acid and discovered that some soft tissue had survived even after 68 million years. The discovery was a shock to the scientific community. No one had ever found such old tissues. Dr. Schweitzer found structures identical to modern red blood cells and blood vessels inside the bone.Which organ system do blood cells and blood vessels belong to?A.circulatory systemB.nervous systemC.skeletal systemD.respiratory system

What are two types of selective breeding and how do they compare?

Answers

One way is to eg: two sheep. If you take and egg from the sheep and sperm from a sheep. Then u extract te DNA u want and put it into an empty egg cell. This then gets inserted into a mother and the baby sheep will be born. The second option is to take just a female egg. And take all the DNA from that and then you will have an exact replica. Or you just have inbred a family. They will all be very similar but it will cause a few defects. Hope this helps :-)

Diego is studying compost. He conducted an experiment to see how moisture levels affect the breakdown of organic materials in compost piles. Diego found that adding 1 L of water per 10 kg of dry matter caused the compost to break down at the fastest rate, but adding more than 1 L caused decomposition to slow down. Which of the following questions do these results lead to? I. Why does adding more than 1 L of water per 10 kg cause decomposition to slow down? II. Does this ratio of water to dry matter hold true for all organic materials being composted? III. Why should anybody want to start a compost pile? A. I, II, and III B. I only C. I and II only D. II and III only

Answers

Answer:

Option C , I and II only

Explanation:

The study conducted is done only for people or organisations that either started a compost pile or who want to start a compost pile. Thus result III is not at all a valid question for the study conducted.

However, there can be question related to the result of experiments clarifying the quantity of additives used in the experiment for example why only 10 Kg of dry water, why not to add more than 1 L of water , why only water is to be added why not some other solvent etc. Thus question I is a valid question.

Also , question II is valid as it asks about expanding the scope of experiment from one type of organic material to all other type of organic matter in the compost.

There fore both question I and II are valid question and thus option C , is correct.

How is gravity affected by mass and radius?

Answers

Gravity is directly proportional to the difference in mass ( thus, the greater the difference in mass of two objects, the greater the gravity).

Gravity is inversely proportional to the square of radius between two objects ( thus, the greater the distance from radius, thus, the lesser the gravity)

* Well if you mean the radius of an object, then it is directly proportional; greater the radius, greater the gravity.*
