Answer: Black allele has frequency of 0.14.
Red allele has frequency of 0.86.
The frequency of heterozygotes is 0.241
Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:
[tex]p+q=1[/tex]
[tex]p^{2}+2pq+q^{2}=1[/tex]
p represents frequency of dominant allele;
q represents frequency of recessive allele;
2pq is frequency of heterozygotes;
For the frequency of red allele, which is dominant, we can use:
[tex]p^{2}=\frac{37}{13+37}[/tex]
[tex]p^{2}=\frac{37}{50}[/tex]
[tex]p^{2}=0.74[/tex]
[tex]p=\sqrt{0.74}[/tex]
p = 0.86
For the black allele:
[tex]p+q=1[/tex]
[tex]q=1-p[/tex]
[tex]q=1-0.86[/tex]
q = 0.14
Frequency of heterozygotes is
2pq = 2(0.86)(0.14)
2pq = 0.241
Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.

Answer:
According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.
Explanation:
G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.
G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.

Why is it necessary to digest corn starch?
Answer:
Your digestive system breaks down carbohydrates into glucose, which your body uses as fuel. Without the fiber, fat or protein to slow down this process, cornstarch provides your body with energy more quickly than whole-grain carb
It is essential to digest corn starch because it is the carbohydrate that provides energy after digestion, and if it is not digested properly, various diseases will develop.
What is the digestive significance?Digestion is a process in which animals simplify complex food into smaller molecules that can be absorbed and used for energy and nutrition, and it is important for animals because it enables them to extract the nutrients they need to survive and thrive, for proper digestion, animals have a complex system of organs and enzymes that work together to break down different types of nutrients, for example, the stomach produces hydrochloric acid and enzymes that help break down proteins, while the small intestine absorbs sugars, fats, and other nutrients.
Hence, it is essential to digest corn starch because it is the carbohydrate that provides energy after digestion, and if it is not digested properly, various diseases will develop.

Which type of cell must be produced more frequently than the other types?
1)brain cells
2)red blood cells
3)muscle cells
4)liver cells
5)stomach lining cells
Answer:
3 because the muscle cells is produced
Red blood cells are produced more frequently than the other types, the body produces them every second, hence option 2 is correct.
Why do red blood cells produce more frequently?Medication that promotes the formation of RBCs: Erythropoietin is a hormone that is made in the liver and kidneys and stimulates the production of RBCs in the bone marrow. Some types of anemia can be treated with erythropoietin.
In order to replace those red blood cells that eventually deteriorate and die, red blood cells are continuously created in the bone marrow. A red blood cell has a lifespan of roughly 120 days on average. Anemia and shortness of breath result from a large drop in the number of red blood cells.
Therefore, It just takes a few weeks to replenish red cell reserves because your body produces roughly 2 million new ones every second.

this molecule?
9. Analyze What elements are present in this
molecule?
10. Solve What is the chemical formula of this
organic compound?
Answer:
Explanation:
The structure represented in the picture attached to the question is a benzoic acid (which is an organic compound).
8. The type of bond present between the carbon-carbon, carbon-hydrogen and carbon-oxygen atoms in the compound (same as other organic compounds) is a covalent bond. This is because oxygen and hydrogen share there valence electrons with carbon; oxygen has two valence electrons and thus it is surrounded with two bonds and hydrogen has one valence electron and thus surrounded with one bond.
9. The elements present in this compound, as can be seen in the picture, are carbon, hydrogen and oxygen which is the reason it is referred to as an organic compound.
10. The chemical formula of this organic compound is C₆H₅COOH. The "cyclic" structure (aromatic structure) there shows that it is a derivative of benzene (because of the presence of the alternating double bonds) while the carboxylic group there has to be written separately in the formula.

observations?
O A. Form a hypothesis.
O B. Conduct an experiment.
OC. State the problem.
O D. Draw conclusions.
Answer:
D. Draw conclusions
Explanation:
The scientific method
At the core of biology and other sciences lies a problem-solving approach called the scientific method. The scientific method has five basic steps, plus one feedback step:
Make an observation.
Ask a question.
Form a hypothesis, or testable explanation.
Make a prediction based on the hypothesis.
Test the prediction.
Iterate: use the results to make new hypotheses or predictions.
The scientific method is used in all sciences—including chemistry, physics, geology, and psychology. The scientists in these fields ask different questions and perform different tests. However, they use the same core approach to find answers that are logical and supported by evidence.
Which of the following statements is true?
A.
The Earth's lithosphere is entirely made up of liquid magma.
B.
The Earth's mantle is made up of tectonic plates.
C.
The Earth's mantle is made up of continents.
D.
The Earth's lithosphere is made up of tectonic plates.
Answer:
D. The Earth's lithosphere is made up of tectonic plates.
Explanation:
The lithosphere is the Earth's outermost layer. It is made up of the brittle crust and upper mantle. Lithosphere is consist of huge slabs known as tectonic plates. These plates are present on the top of molten layer (partially) of rock. The heat from the mantle allows the bottom of the rocks soft and cause plates to move.
There are two main types of tectonic plates called oceanic and continental.
Hence, the correct answer is "D. The Earth's lithosphere is made up of tectonic plates."
The Earth's lithosphere is made up of tectonic plates. The correct option is D.
Thus, The Earth's lithosphere, which is its solid outer layer, is made up of numerous large and small tectonic plates that move and float on the asthenosphere underneath.
Along plate borders, these plates, which are made up of both continental and oceanic crust, interact with one another, causing a variety of geologic events like earthquakes, volcanic eruptions, and the construction of mountain ranges.
Liquid magma (A) or tectonic plates (B) do not make up the complete lithosphere; rather, tectonic plates are a part of the lithosphere. The mantle of the Earth, which sits underneath the crust, is made up of solid rock materials rather than continents (C).
Thus, The Earth's lithosphere is made up of tectonic plates. The correct option is D.

What's the relationship between photosynthesis, chlorophyll, thylakoids, and chloroplasts?
Answer:
The structural unit of photosynthesis is the chloroplast. Prokaryotic and eukaryotic photosynthetic organisms possess flattened sacs or vesicles called thylakoids, which contain photosynthetic pigments. Chlorophyll molecules are attached to specific proteins embedded within membranes, along with carotenoids and other components necessary for photosynthesis.
Explanation:
Chloroplasts are typical and exclusive organelles of plant cells that possess chlorophyll. Because of them, plants are capable of carrying out the photosynthesis process, a process that transforms light energy into chemical energy contained in ATP molecules. The inside is filled with a gel called a stroma. It presents a DNA independent of the nucleus and plastoribosomes. Immersed in the stroma, there are flattened sacs called thylakoids or lamellae, the interior of which is called lumen. Thylakoids can spread throughout the stroma or stack in bundles called grana. In the membrane of grana or thylakoids are located the enzymatic systems that capture the energy of the sun and carry out the transport of electrons to form ATP.
