in humans, dimples are dominant to no dimples. cross a woman with no dimples with a man who is heterozygous for dimples. determine the phenotypic and genotypic ratio of their offspring. show a punnett square to support your answer
Answers
Genotype: 50% Aa and 50% aa
Phenotype: 50% Dimples and 50% no dimples
Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.
Hope this helps!

You haven't provided the options you were given, but I can try to help you out with your question anyway.
Photosynthesis is a process in which most plants and some bacteria and protists create food. Organelles that enable them to do this are called chloroplasts. They contain a green pigment called chlorophyll. With its help, all of these organisms use water, minerals, carbon dioxide, and energy from the sun to produce oxygen, which they release back into the atmosphere, and sugars, which they use as food.
You can use this information to determine which answers are correct.

What trends do you see with regard to CO2 concentration? What about average global temperature trends?
Answers
Answer:
The CO2 concentration in the air increased, and temperatures increased too.
Explanation:
PLATO answer
The temperature change shows a relationship with the carbon dioxide concentration in the atmosphere. The carbon dioxide concentration in the air increased, as a result the temperature of the atmosphere increased too.
What are the global temperature trends?The global temperature trend is the average rate of increase or decrease in the temperature at the grid points over the specific time period of interest. Global temperature trend is determined by the simple linear regression through the data which is available for each of the grid points. These are expressed in degrees Celsius per decade.
The carbon dioxide concentration in the atmosphere shows a linear relationship with the temperature of that region. When there is more carbon dioxide in the atmosphere, it makes the atmosphere warmer through heat trapping. Since, humans are adding more carbon dioxide the atmosphere continuously, that helps to explain why the temperatures are increasing around the world continuously.

Which prediction will most likely describe how friction will affect her findings? The distance for Trial 3 will be greater than the distance for Trial 1 partly because the weight difference of the balls will affect friction. The distance for Trial 2 will be greater than the distance for Trial 1 because the difference in surface roughness will affect friction. The distance for Trial 4 will be greater than the distance for Trial 2 partly because the weight difference of the balls will affect friction. The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Answers
The complete question is :
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
Which prediction will most likely describe how friction will affect her findings?
Answer:
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Explanation:
The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.
In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :
F' = F - f
Here, F = the force applied
f = force of friction
And f = μ.N (N = reaction force)
Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.

How do choroplast in guard cells control the turgidity of the guard cells. Controlling the stoma. (i know that water flows in and the guard cell becomes turgid, but how does the guard cell control the water flow?)
Answers
Answer:
The correct answer is letter A. Potassium makes guard cells become turgid when water flows within this protective barrier. This happens so that the plant can perform photosynthesis even without the presence of direct sunlight. The pores of the cells start to contract and conserve water so that the plant can use it later on.

Describe the discovery of the importance of DNA including descriptions of at least two experiments
that lead scientists to the knowledge we now have today.
Ah this is due in 40 minutes :,)
Answers
Explanation:
Introduction
Our modern understanding of DNA role in heredity has led to a variety of practical applications, including forensic analysis, paternity testing, and genetic screening. Thanks to these wide-ranging uses, today many people have at least a basic awareness of DNA.
It may be surprising, then, to realize that less than a century ago, even the best-educated members of the scientific community did not know that DNA was the hereditary material!
In this article, we'll look at some of the classic experiments that led to the identification of DNA as the carrier of genetic information.
Protein vs. DNA
The work of Gregor Mendel showed that traits (such as flower colors in pea plants) were not inherited directly, but rather, were specified by genes passed on from parents to offspring. The work of additional scientists around the turn of the 20th century, including Theodor Bovari, Walter Sutton, and Thomas Hunt Morgan, established that Mendel's heritable factors were most likely carried on chromosomes.
Scientists first thought that proteins, which are found in chromosomes along with DNA, would turn out to be the sought-after genetic material. Proteins were known to have diverse amino acid sequences, while DNA was thought to be a boring, repetitive polymer, due in part to an incorrect (but popular) model of its structure and composition1
start superscript, 1, end superscript.
Today, we know that DNA is not actually repetitive and can carry large amounts of information, as discussed further in the article on discovery of DNA structure. But how did scientists first come to realize that "boring" DNA might actually be the genetic material?
