A cross-section of a tree trunk shows 20 dark-colored rings and 20 light-colored rings. What is the likely age of this tree?

Answers

Answer 1

Answer: Trees produce 2 colored rings per year and so by counting these rings you can have an idea as to how long the tree has lived. With 20 dark-colored rings and 20 light-colored rings, the tree is likely to have stood up for 20 years. I hope this helps.

Answer 2

Answer: The likely age of a tree that shows 20 light colored rings, and 20 dark colored rings is 20 years old. Each year of a tree's life is represented by a dark and a light part. The type of life that a tree has had can also be learned by looking at the rings. If rings are not even or concentric you can tell that a tree was leaning, or was growing in a windy area. You can also judge the health of a tree by how the rings are spaced.

Acupuncture is an alternative medicine that uses wire-thin needles inserted by a trained practitioner into specific points in the body. This ancient form of pain relief and stimulation is said to benefit patients by blocking channels which practitioners claim allow pain to travel within the body. This practice became more widely recognized and used after a New York Times reporter wrote in 1971 of a positive experience with it after surgery. Those who doubt the effectiveness of this treatment for pain attribute the pain relief to a placebo effect: if a patient believes something will reduce

Answers

Answer:

if a patient believes something will reduce their pain, they will experience some relief.

Explanation:

Acupuncture was already considered an esoteric technique, since it was based on a little deep knowledge, where the patient's conviction that his pain would be diminished provided a relief from the inconvenience, but acupuncture was recognized by the World Health Organization (WHO) as a and was also listed as a UNESCO World Heritage Site.

If a patient believes something will reduce, their minds cause their bodies to take that reduction into effect.

Which of the following is an example of radiation?A. A metal spoon becomes warm after being set in a pot of boiling water.

B. Warm water rises because it is less dense than cool water.

C. Pancake batter cooks quickly after being spooned onto a hot griddle.

D. Our atmosphere is constantly being heated by the sun.

Answers

Answer: D. Our atmosphere is constantly being heated by the sun.

Radiation is the transmission of energy in the form of waves or particles released by one source and absorbed by another source. Types of radiations includes electromagnetic radiation, particle radiation, acoustic radiations and gravitational radiations.

Our atmosphere is constantly being heated by the sun is the example of the radiation because the sun radiates energy in all directions in the form of heat, light and radiations. Solar energy in the form of radiation is either reflected back to the sun or it is absorbed by the earth atmosphere. Therefore, this causes heating up of the earth atmosphere.

D. Our atmosphere is constantly being heated by the sun is an example of radiation.
A has to do with convection, B with density difference, C with conduction.
Radiation is a great problem because it is constantly destroying our ozone layer which protects us from Sun beams.

Predict the offspring of two white homozygous cats. Black is dominant to white. Use B for dominant and b for recessive. what are the genotypes and phenotypes of the new generation? what are the percentages of round and wrinkled plants?

Answers

Answer:

Genotype of offspring: bb

Phenotype of offspring: white

Percentage of white offspring: 100%

Percentage of black offspring: 0%

Explanation:

Black with allele B is dominant to white with allele b.

Homozygous white will have the genotype bb.

Crossing two homozygous white cats:

bb x bb = bb, bb, bb, and bb

All the offspring will be homozygous white with bb genotype.

Percentage of the offspring that are white = 100%

Percentage of the offspring that are black = 0%

Answer:

The offspring will also be white and homozygous.

Explanation:

If the two cats are white and homozygous where the gene B is for black color and dominant, gene b is for white color and recessive. In this case the genotypes of the two cats are going to be "bb" which can only lead to the same genotypes and phenotypes in their offspring. They will also be white and homozygous.
