A gene for corn has two alleles, one for yellow kernels and one for white kernels. A farmer mates yellow and white corn. All of

the offspring have a nearly even mix of yellow and white kernels. Which type of inheritance most likely explains the relationship between the two alleles?

Answer: Codominance.

Explanation:

Codominance is a relationship between two parts of a gene. Offspring get one part of a gene, known as an allele from each parent. When the alleles are different, a dominant allele is usually expressed and the effect of the allele is usually covered or masked which is recessive. However, when Codominance occurs, neither of the alleles is recessive and phenotypes of both alleles are expressed.

In the above case, mating the yellow and white corn by the farmer resulted in offsprings that have nearly an even mix of both white and yellow corn. This is known as Codominance because no allele appeared to be recessive. The phenotype of both the alleles for yellow and white corn are expressed in the offsprings.

3. What did scientists find in the burial site? The scientist found nine skeletons.

What did they not find?They did not find two of them which was believe to be that of Princess Anastasia and her brother Prince Alexei

4. What did the mitochondrial DNA testing show? DNA testing showed that it certainly was Nicholas, Alexandra and the three children, these was discovered through the bones found in the grave

What do scientists believe happened to Anastasia?Scientist believed that Princess Anastasia along with her brother Prince Alexei were cremated aright after they were being killed

5. Why do you think it took so long for this mystery to be solved? it took so long for this mystery to be solved because  the technology available can not be compare to  DNA technology because modern technology and advancement had made it more better and convenient .

What factors played a role? DNA technology played a role

Black coffee has a pH around 5; hand soap has a pH of 10. How many times more acidic is coffee relative
Anon25 [30]

Answer:

\boxed {\boxed {\sf 10^5 \ or \ 100,000 \ times \ more \ acidic}}

Explanation:

The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.

This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.

So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:

10^ {difference \ in \ pH}

The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.

10^5=100,000

Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>

So, what is actually produced during the light reaction? Do you know the chemical<br> equation?
Alex_Xolod [135]

Answer:

The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. 5. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.

skad [1K]
Elbow dysplasia is an inherited developmental abnormality that affects the elbow joint of dogs. It is accepted that the offspring of <span>a </span>dog<span> with the condition are likely </span><span>to develop the condition themselves. Therefore, the likely answer is:  '</span>It has low diversity in its genes'. Even though the dog is a mixed breed, it is possible that one or both parents carried the gene for a predisposition to elbow dysplasia.

Summarize Isaac Newton's law of gravity
tankabanditka [31]
Newton's law of gravity defines the attractive force between all objects that possess mass. Understanding the law of gravity offers profound insights into the way our universe functions. Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree. <span>Newton knew that the force which caused the apple's acceleration (gravity) must be dependent upon the mass of the apple. And since the force acting to cause the apple's downward acceleration also causes the earth's upward acceleration (Newton's third law), that force must also depend upon the mass of the earth. </span>
