In mice, black color (B) is dominant to white (b). At a different locus, a dominant allele (A) produces a band of yellow just below the tip of each hair in mice with black fur. This gives a frosted appearance know as agouti. Expression of the recessive allele (a) results in a solid coat color. If mice that are heterozygous at both loci are crossed, ___ out of 16 will be black in color.
Answers
Answer:
3
Explanation:
Heterozygous mice at both loci would be BbAa genotype.
B (black) is dominant over b (white) but the presence of A results in agouti.
Crossing two heterozygous:
BbAa x BbAa
Progeny
9 B_A_ - Agouti
3 bbA_ - agouti
3 B_aa - Black
1 bbaa - white
Hence, 3 out of 16 progeny will be black in color.
See the attached image for the Punnet's square analysis of the cross.

O Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same container. What does this tell you about the make-up of the pigments for each specimen?
Answers
Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.
How do the biotic and abiotic factors you circled interact?
Answers
Answer:
Explanation:In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients. The water, phosphorus, nitrogen, and carbon cycles are examples of this. Another way biotic and abiotic factors interact is that biotic factors often change the geology and geography of an area.

Primary Succession
Secondary Succession
Tertiary Succession
Aquatic Succession
Answers
Answer:
Primary Succession
Explanation:
This is the first step for an environment in terms of its life cycle. The first plants (pioneer plants to be specific) to inhabit this new island will help make a layer of soil that the Secondary Succession stage will not have to go through. The creating of soil takes THOUSANDS OF YEARS so this would be associated with Primary Succession.

In which part of the Sun would the most helium be found? *
(20 Points)
Answers
Answer:
yes D part have most helium
The most helium in the Sun is found in its core. The core in the given image is represented by letter D.
What is nuclear fusion?Nuclear fusion is the reaction that occurs when two or more atomic nuclei combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons).
Nuclear fusion reactions take place in the Sun's core, converting hydrogen into helium and releasing energy in the process.
As a result, the core of the Sun has the highest concentration of helium, accounting for an estimated 60% of the Sun's total mass.
The outer layers of the Sun have much lower helium concentrations and are mostly made up of hydrogen.
Thus, the correct labeling is D.

The symptoms that a doctor says indicate that there is a problem with one's body are that the sugar in urine, which is in the second option, is not normal because the sugar returns to the blood during the filtration.
What is the significance of the urine abnormality?High levels of sugar in the urine indicate uncontrolled diabetes and metabolic disorders like the Fanconi syndrome, where the body is unable to reabsorb sugar from the urine. This can lead to high levels of sugar in the blood, which can damage blood vessels and lead to serious health complications.

1. What is the gradual change in populations over time?
2. What is the idea that species originate in small gradual steps over time?
Answers
1. Gradualism
2. evolution
Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.
2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).

Answers
Answer:
The white one as it would blend in better ie be camouflaged and less at risk to be eating by a predator
Explanation:
The moth that would survive in the bunch of trees pictured is white pepper moth.
What is camouflage?Camouflage, also known as cryptic coloration, is a defence or tactic used by organisms to conceal their appearance, usually in order to blend in with their surroundings.
Camouflage is used by organisms to conceal their location, identity, and movement. This enables prey to avoid predators while also allowing predators to sneak up on prey.
The peppered moth (Biston betularia) is a night-flying moth found in temperate regions.
The light-colored moths were difficult to see as the soot lightened the trees.
They were less likely to be eaten by birds, whereas dark-colored moths could blend in better on darker trees. As a result, dark-colored moths had a lower survival rate.
Thus, there is better survival rate of white moths in the given scenario.

Answer:As one example, think about a building's electrical system. Suppose a mouse chewed through an electrical wire to a furnace. Without electricity, the heating system would not work. If this happened in very cold weather, the plumbing system could be affected. Water pipes might freeze and burst. If a lot of water leaked into the building's walls, its support system would be damaged. Like a building's systems, your body's systems have
Explanation:
You know that your body is made of cells. When groups of cells do the same kind of work, they are called tissues. The word tissue comes from a Latin word meaning to "weave." Cells that make up tissues are sometimes "woven" together.
You have four main types of tissues: epithelial, nervous, muscle, and connective tissue. Epithelial tissue covers the outside of the body. It also lines organs and cavities. Nervous tissue sends electrical signals. Muscle tissue helps you move. Connective tissue joins bones and cushions organs.
When groups of tissues work together, they are called organs. Some
examples of organs are the heart, lungs, skin, and stomach. When organs work together, they are called systems. For example, your heart, lungs, blood, and blood vessels work together. They make up the circulatory system.
There are eleven systems in the human body: muscular system, respiratory system, digestive system, integumentary system (skin), skeletal system, circulatory (or cardiovascular) system, excretory (or urinary) system, reproductive system, nervous system, lymphatic system, and endocrine system. Each system has a special job.
All of your body systems have to work together to keep you healthy. Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide.
Think of your body as a building. A building has a plumbing system, a heating system, a cooling system, an electrical system, and a support system. If any system in a building breaks down, other systems can be affected.

Answers
The protein function listed here which suggests that most enzymes are proteins is that they speed up chemical reactions. That is option D.
Proteins are one of the classes of food that contains nitrogen in addition to carbon, hydrogen and oxygen.
Enzymes are those substances that helps in the breaking down of food substances into simple, soluble and diffusible substances before they can be absorbed into the body. It speeds up chemical reactions in the body by lowering the activation energy.
Enzymes are often referred to as proteins because proteins speeds up biological processes (chemical reactions) which is the same function performed by an enzyme in a living organism.
