how does a wave change direction when it bounces off a surface?​

Answers

Answer 1
Answer: Waves change direction by reflection, refraction, and diffraction. Reflection – when a wave hits a surface, any part of the wave that cannot pass through the surface bounces back. This interaction with a surface is called reflection. When you look in a mirror, you see reflected light to see yourself.

In the logistic growth model, as a population approaches the carrying capacity, what happens to its growth rate?
A
becomes exponential

B
doubles

C
increases

D
slows to zero

Answers

I am pretty sure it is D slows to zero, don’t get mad at me if I’m wrong I’m pretty sure I am correct though.

In the logistic growth model, as a population approaches the carrying capacity, the growth rate of the population will slow down to zero. Thus, the correct option is D.

What is Logistic growth model?

The logistic growth model is a parameter which represents the rate at which the population would grow if it were unencumbered by the environmental degradation. A second parameter, that is K, represents the carrying capacity of the system of species which are being studied.

In logistic growth, a population's per capita growth rate gets smaller and smaller as the population size when it approaches a maximum imposed by the limited resources in the environment, known as the carrying capacity (K). Exponential growth model produces a J-shaped curve, while logistic growth produces an S-shaped curve.

Therefore, the correct option is D.

All of the following are true about thymine dimers EXCEPT: the type of repair that is done to fix them is called nucleotide excision repair they are caused by UV radiation damage that fuses thymines that are next to each other on the same strand individuals with xeroderma pigmentosa (XP) are unable to repair this type of DNA damage, leading to cancer cell development they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands

Answers

Answer:

Option 4, they are caused by UV radiation damage to thymines that are opposite each other on different DNA strands

Explanation:

Thymine dimer is formed on adjacent thymine and hence they lie next to each other on the same strand. They do not lie on strand that are opposite of  each other on different DNA strand.

Hence, option 4 is correct

Producers, consumers, and decomposers play important roles in the environment. Are there any organisms that would not fall into one of these categories? Explain your answer.

Answers

Answer:

No, there are no organisms that will not fall into these categories

Explanation:

Living organisms interact with one another in their natural environment in order to ensure that energy needed for their metabolic activities is obtained. To do this, each organism plays different or specific roles. The roles that every organism must fall into are as follows:

- Producers are groups of organisms that have the ability to synthesize their own food using light (photosynthesis) or chemicals (chemosynthesis). Examples are green plants, algae, some bacteria etc.

- Consumers- These are organisms that lack the ability to synthesize their own food and hence depend on other organisms for their energy source. Consumers can either be herbivores (eat plants) or carnivores (eat flesh) etc. Examples are all animals etc.

- Decomposers- These are organism that have the ability to breakdown dead organisms into organic matter, thereby, adding nutrients back to the soil. Examples are fungi, bacteria, earthworm etc.

Based on this explanation above, no organism will not fall into any of these three categories. Some can even occupy two roles.

A. An addition mutation occurred
B. A deletion mutation occurred
C. A substitution mutation occurred
D. A mutation did not occur.

Answers

C

I think substitution, because the original translation of the original base sequence is glutamine-leucine-proline. The base sequence for valine-tyrosine-glycine is: GT#  TA#  GG# . of course the last codon is unclear, but the first two gives us enough to know too much change happened for a simple addition or deletion mutation. The bases were completely switched out, therefore it is a substitution mutation. I attached a codon chart.

Today, Regenerative Medicine is trying to employ these cells to replace tissues that have been destroyed by disease and trauma, such as spinal cord injuries. What are these cells

Answers

Answer:

These cells are stem cells.

Explanation:

Stem cells have not specialized to be in a specific tissue and have a particular function yet. They are the cells that give all the different cell types that our body has. In other words, they can become any cell type that the body needs. We call them pluripotent cells because they have the potential of becoming any specialized cell.

Scientists use stem cells in tissue or organ regeneration due to the pluripotential that they have.

Answer:

Explanation:

If the gene for purple flowers is dominant and two white flowered plants produce 6 offspring, then the answer must be 6. Every life form with genes has a dominant and recessive gene. For example, on a child’s fathers side there is a history of large ears. On the child’s mothers side there is a history of small ears. The father’s large ear size is dominant, so the child will have large ears. If two white flowers are white instead of purple that must mean that the dominant purple gene was not in their flower history. Therefore, their offspring will have no chance of developing a purple colour.

A big, powerful male gorilla is much more likely than a smaller, weaker
gorilla to become the population's silverback, the pack's leader who mates
far more than the other males of the group. The pack leader will, therefore,
father more offspring, who share half of his genes, and are thus likely to also
grow bigger and stronger like their father. Over time, the genes for bigger
size will increase in frequency in the population, and the population will, as a
result, grow larger on average.

If u want to know what students think is the best season of the school year from school 76, what is the best way sample the students? Read the passage.A Flag with 50 StarsThe first American flag to have red and white stripes and white stars on a blue field was flown in 1776, shortly after the United States declared its independence from Great Britain. Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student.In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change his grade to an A.A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Question 1Part AWhat inference about the flag can be made based on a A Flag with 50 Stars?Few people understand the significance of the number of stars and stripes on the flag. The placement of stars on the flag has been a design challenge throughout history. The decision to change the design of the flag has always cause controversy. Its past history is more well known by Americans than its more modern history.Question 2Part BWhich evidence from the text best supports the answer in Part A?There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes.Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag.Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag.The U.S. flag at the time had six neat rows of eight stars each.
