Answer:
a
Explanation:
The phenotypic ratio is the depiction and the relation of the occurrence of the phenotype in the offspring. The phenotypic ratio of 9:4:3 indicates codominance. Thus, option A is correct.
What is codominance?Codominance is the inheritance where both the recessive and the dominant allele are expressed in the offspring independently to produce the individual with the expression of both the trait separately.
The blood group, eye color, roan cattle, flower colors, sickle-cell anemia, etc., are some examples that show the pattern of codominance. The phenotypic ratio suggests the occurrence of the physical traits in the offspring that are visible.
In codominance, the phenotypic ratio is 9:4:3 as both the traits possessing alleles are independently expressed in the next generation.
Therefore, 9:4:3 is the phenotypic ratio of codominance.

1. What percentage of puppies would have the same genotype as the
parents, Ww?
Answer:
50%
Explanation:
This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.
Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.
"The bird has brown spots on its wings" is an example of an inference,
True
False
The area of the picture highlighted by the green square is a monomer of nucleic acids(DNA/RNA). Which of the following is the name for that monomer?
A. phosphate backbone
B. thymine
C. nucleotide
Answer:
C. Nucleotide
Explanation:
There are four types of biological molecules existing in nature. These are: carbohydrates, proteins, lipids, and nucleic acids. Nucleic acids are biological polymers made up of monomeric units called NUCLEOTIDES.
A nucleotide as depicted in the attached image is a molecule made up of three components namely; Penrose sugar, phosphate group, and nitrogenous base (adenine, guanine, cytosine and thymine). Based on the image in this question;
A represents ADENINE
S represents SUGAR
P represents PHOSPHATE GROUP
Hence, the monomer is a NUCLEOTIDE.
What type of microbe is used in a vaccine .
Answer:
answer is below
Explanation:
Several of these structures have been used to generate bacterial vaccines. Toxoids are chemically inactivated toxins from bacteria like Clostridium tetani or Corynebacterium diphtheria. The infection with these bacteria itself does not cause the illness, but rather the exotoxins released from the bacteria.
Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine.

The missing part of the question is -
" Is this Primary or Secondary Succession?"
Answer:
The correct answer is - secondary succession.

Ion pumps and phagocytosis are both examples of
________.
a. endocytosis
b. passive transport
c. active transport
d. facilitated diffusion
Answer:
A
Explanation:
EDGE2021
Ion pumps and phagocytosis are both examples of active transport. Therefore, the correct option is C.
The movement of molecules or ions across the cell membrane against a gradient of concentration, from an area of lower concentration to an area of higher concentration, is called active transport. In this whole process energy must be used in the form of ATP (adenosine triphosphate).
Ion pumps are membrane proteins that actively transport ions across the concentration gradient across the cell membrane. These ions include sodium, potassium, calcium or hydrogen ions. The ion concentration imbalance required for many cellular functions is maintained by these pumps.
On the other hand, phagocytosis is a type of endocytosis in which cells engulf large molecules or solid particles and internalize them. Energy is required for the formation of pseudopods and for the solubilization of substances in the phagosome inside the cell.
Therefore, the correct option is C.

Answer:
D.
Explanation: Which pieces of information does the National Weather Service produce?
simple maps
newspaper maps
long-range forecasts
maps with isotherms
The National Weather Service produces long-range forecasts and maps with isotherms, but not simple maps or newspaper maps.
What is long- range forecast?Long-range forecasts are predictions of weather conditions that are expected to occur over a period of several days or weeks. These forecasts are typically based on computer models that analyze current weather data and historical weather patterns.
Isotherms are lines on a map that connect points with the same temperature. They are commonly used to show temperature patterns across a geographic region, and can be useful for understanding weather conditions and climate trends.
While the National Weather Service may produce maps, they are typically not simple maps or newspaper maps, as their focus is on providing accurate and detailed weather information to the public and other stakeholders.

Invert syrup is a widely used sweetener, especially in candies and highly processed foods. Invert syrup can be made by treating sucrose with either an enzyme called sucrase or by heating sucrose with an acid. The end result is the same: each molecule of sucrose is hydrolyzed, resulting in _
Answer:
one glucose and one fructose molecule
Explanation:
Generally, inverted sugar is a mixture of two monosaccharides or simple/reducing sugars. More specifically, inverted sugar is a mixture of glucose and fructose.
Sucrose is a disaccharide containing one molecule of glucose and one molecule of fructose. Hence, when hydrolyzed, the glycosidic bond linking the glucose molecule with the fructose molecules becomes broken and the resulting product is a mixture of glucose and fructose molecules in equal proportions.

walrus often dive for 5 to 8 minutes suggest why having over three times as many red blood cell as humans help them perform this function
Walrus often dive for 5 to 8 minutes because their red blood cells (that carry the oxygen) are exceptionally large. In addition, they have lots of myoglobin in their muscles that can store oxygen.
Why do Walrus have high blood circulation?The walrus can remain under the surface of the water for up to 10 minutes. They will usually surface every 5 to 8 minutes to get air and stay at the surface for about 1 minute. They will stay in the shallow waters, no more than 262 feet below the surface.When they dive the blood flow is cut off from their skin, extremities, and stomach. All of these adaptations allow for efficient and lengthy use of oxygen stores. They have a larger percentage of blood in their bodies to carry oxygen, about 12 percent of their weight as compared to only 7 percent for humans.To learn more about Walrus, refer to:https://brainly.com/question/25164635

Why do mapping experiments become less accurate when the distances between genes become large? View Available Hint(s) Why do mapping experiments become less accurate when the distances between genes become large? Interference is greater when the distance between genes is large. Multiple crossovers are more common. Crossover gametes become less common. Recombination occurs less frequently in long chromosomes.
Answer:
Multiple crossovers are more common.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
A mapping experiment refers to an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In mapping experiments, if the genetic distance increases, there would be a consequential increase in multiple crossovers causing a recombinant with an odd number of crossovers and a parental combination with an even number of crossover events by switching it back.
Hence, mapping experiments become less accurate when the distances between genes become large because multiple crossovers are more common.

Answer: 1200
Explanation:
If it was 1250 J of work done, and a object that weights 50 N, you subtract 50 from 1250 which is 1200 J. Work has been done, so you subtract the high number from the lowest.
