A strain of a cereal grain can be either dark tan, medium-dark tan, medium tan, light tan, or cream colored. When a dark tan and a cream plant are crossed, all F1 are medium tan. The F2 are distributed in a ratio of 1:4:6:4:1 from darkest to lightest. How many genes are involved in this coloration?

Answers

Answer 1

Answer:

The correct answer is - 2 genes.

Explanation:

The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:

suppose there are only two gene - TT dominant over tt and CC dominant over cc

then the cross would be - RRCC - rrcc

gametes - RC and rc

Cross F1: RrCc

Self cross in F2:

offspring by Punnet cross are:

RRCC  -->1/16  

RRCc,  RrCC .---> 4/16

RrCc, RRcc, rrCC--->6/16

rrCc, Rrcc--->4/16

rrcc ----> 1/16

thus, the correct answer is 2 genes

If having long fur helps a guinea pig survive, what
would you expect to see change in the population
as it evolves?
DONE

Answers

The population would increase, since they live longer and more can mate and reproduce.

In a population with long fur, there will be more guinea pigs than short fur in the given scenario.

What is trait?

A trait, as it relates to genetics, is a unique feature of an individual.

If having long fur helps a guinea pig survive, we can expect the long-furred trait to become more common in the population as it evolves.

This is because guinea pigs with long fur would have an advantage in colder environments, allowing them to retain body heat more effectively and survive longer.

As a result, longer-furred guinea pigs are more likely to survive and reproduce, passing on their long-furred trait to their offspring.

As this process continues over many generations, the proportion of guinea pigs with long fur in the population will increase, while the proportion with short fur will decrease.

Thus, this can be expected to see change in the population as it evolves.

Each of the following is a function of the liver, except production of digestive enzymes. The correct option is C.

What are the functions of liver?

The liver is the largest gland in the body and is located in the right upper quadrant of the abdominal cavity. It has over 500 essential functions. They include: Detoxification and purification - The liver is responsible for filtering toxins and harmful substances from the blood, preventing them from entering the bloodstream and harming other organs.

The liver is responsible for synthesizing many important plasma proteins, including albumin and clotting factors. The liver secretes bile, which aids in the digestion of fats and the absorption of fat-soluble vitamins.

The liver stores many essential nutrients, including vitamins and minerals. The liver is responsible for storing glucose as glycogen and regulating glucose levels in the bloodstream.

Therefore, each of the following is a function of the liver, except production of digestive enzymes.

two models of sells are shown below. Why would model b be better for moving nutrients in and out of the cell?

Answers

Answer:

The correct answer is - C. It has a larger ratio of surface area to volume.

Explanation:

In cell B, the ratio of surface area to volume is larger in comparison to cell A. The surface area to volume ratio can be understood as it is the size of surface area that the volume of a particular substance can move in or out of the cell, in a unit of time.

Thus the larger the ratio of surface area to volume faster the diffusion rate of nutrients will be as the surface area is a square measurement and volume is cubed so the surface area increases faster than volume.

Which type of base is shown? How can you tell?

Answers

Answer:

The correct answer is - purine nitrogenous base (adenine).

Explanation:

The base given in the diagram in the image has two rings attach with the pentose sugar which is attached to the phosphate, which means it is the diagram of nucleotide. In this nucleotide base can be either purine or pyrimidine.

Pyrimidines have a single ring structure, whereas purines have 2 ring structures. Adenine and guanine are purines with two ring structures whereas cytosine and thymine are pyrimidines as they have one ring structure. Adenine contains an amine group on C6, and a double bond between N1 and C6.

True or False: Purine is connected to pyrimidine using oxygen bonds.​

Answers

Answer:

False

Explanation:

In DNA double helix molecule, there are four types of nitrogenous bases: adenine, guanine, cytosine and thymine. Purines (i.e., adenine, guanine) and pyrimidines (i.e., cytosine and thymine) hold DNA strands together via hydrogen bonds. In base pairing, guanine always pairs with cytosine through 3 hydrogen bonds, while adenine always pairs with thymine by 2 hydrogen bonds. Hydrogen bonds are a type of dipole–dipole interaction where a hydrogen atom is covalently bonded to a very electronegative atom (e.g., Nitrogen or Oxygen).

Scientists have determined that Earth's interior has layers with different properties. One property is that the inner core is solid. Which of the following statements can be used as evidence to support this property?

Answers

Answer:

Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius.[1][2]

The internal structure of Earth

There are no samples of Earth's core accessible for direct measurement, as there are for Earth's mantle. Information about Earth's core mostly comes from analysis of seismic waves and Earth's magnetic field.[3] The inner core is believed to be composed of an iron–nickel alloy with some other elements. The temperature at the inner core's surface is estimated to be approximately 5,700 K (5,430 °C; 9,800 °F), which is about the temperature at the surface of the Sun.[4]

While tuning a guitar, you realize one of the strings is not the right thickness. The pitch needs to be higher in order for the guitar to be tuned properly, so you replace the string with the correct version. Thickness is not the only thing that has an effect on pitch. How tightly the strings are stretched is also a factor. This is why guitar strings are attached to knobs that can be tightened or loosened. If, after replacing the string, the pitch is a little too high, how should you turn the knob to make it right?

Answer:

cell mutations

Explanation:

The process(es) that explain how cells with identical genetic information can produce cells with distinct structures and functions are cell differentiation and gene expression, which influence the cell to produce different structures.

What is the significance of gene expression?

Gene expression is the process by which the cells can express certain types of genes, and this is possible due to the presence of a certain promoter and enzymes that can access the gene. This makes multicellular animals have different cell types and different cell structures, such as the proteins that are formed in the nervous cell, which are different from the proteins of the skin cell.

A reading comprehension (RC) test on a major college entrance exam provides short English prose passages, and the examinees answer a set of multiple-choice items about the passage. To see if particular items measure something other than RC, investigators gave the RC test without the reading passages to a random sample of psychology students. The investigators reasoned that if questions were measuring knowledge or memory rather than just RC, students would answer questions at a higher rate than chance (20%, since there were 5 choices for each question).
