A white-flowered plant is crossed with a plant that is heterozygous for that trait.
What percentage of the offspring will have purple flowers?
A white-flowered plant is crossed with a plant that is heterozygous for that trait; therefore, in this scenario, 50% of the offspring will have purple flowers, while the other 50% will have white flowers.
Only half of the offspring (50%) will have a purple flower phenotype, meaning they will display the dominant trait. This is because they must inherit a P allele from both parents to display the purple flower phenotype, which can only happen if the heterozygous plant contributes a P allele. The other half of the offspring (50%) will inherit the W allele from both parents and display the recessive white flower phenotype.

what certain molecules are used for nadh in cellular respiration
NADH is produced during cellular respiration through the oxidation of glucose in glycolysis and the citric acid cycle.
Glucose is broken down into pyruvate in glycolysis, and NAD+ is reduced to NADH. Pyruvate is then converted to acetyl-CoA in the transition reaction, and NAD+ is again reduced to NADH. It produces one NADH molecule per pyruvate molecule.
In the citric acid cycle, acetyl-CoA is oxidized to carbon dioxide, and NAD+ is reduced to NADH. These molecules are used to produce ATP, the energy currency of the cell, through the electron transport chain.

When do brown parents produce white offspring?
If both parents are carriers of a recessive gene for white color, they may produce white offspring if the gene is inherited by the child from each parent.
A carrier is a person who carries a gene mutation for a particular disease or condition but does not necessarily display any symptoms of the disease.
Carriers usually have one normal gene and one mutated gene, and the normal gene is usually enough to prevent the development of the disease.
If both parents carry a recessive gene for white colour, their offspring may be white if the gene is inherited in child from both parents.
If the parents are not entirely brown but have some genetic diversity, this scenario is more likely.
Thus, it is important to understand that skin colour is a complex trait that is influenced by multiple genes rather than being determined by a single gene.

Evolution by natural selection has been interpreted as “the strongest survive.” This is false; the strongest individuals in a population don’t always survive. Why? So, what is evolution by natural selection?
You are correct that the popular interpretation of natural selection as "the strongest survive" is false. Evolution by natural selection is a much more nuanced process, and it involves more than just physical strength.
Natural selection is a mechanism of evolution that works by differential survival and reproduction of individuals within a population. It occurs when there is variation in a trait within a population, and that trait affects the ability of individuals to survive and reproduce. Individuals with traits that give them a reproductive advantage in their environment are more likely to pass those traits on to their offspring, while individuals with less advantageous traits are less likely to pass on their genes.
The traits that give individuals a reproductive advantage can vary depending on the environment. For example, in a predator-rich environment, traits that improve an individual's ability to detect or evade predators might be advantageous, while in an environment with abundant resources, traits that increase an individual's ability to acquire and store resources might be advantageous.
Physical strength is just one possible trait that could affect an individual's ability to survive and reproduce. Other traits, such as intelligence, disease resistance, and social skills, could also be important. So, while the strongest individuals in a population might have an advantage in certain situations, they might not necessarily be the ones that are most successful overall.
In summary, natural selection is a process of evolution that operates through differential survival and reproduction of individuals with advantageous traits in their environment. It is not simply a matter of "the strongest survive," but rather a more complex and nuanced process that depends on the specific traits that are advantageous in a given environment.
Why do we separate the immune system into nonspecific and specific defenses?
Will mark brainliest!!!!!!!!!!
Answer:
to categorize and describe the different ways in which the immune system responds to pathogens and other foreign substances in the body.
Explanation:
Nonspecific defenses, also known as innate or natural defenses, are the first line of defense that the body has against infections. These defenses are present from birth and provide a general, immediate response to a wide range of pathogens, regardless of their specific nature. Examples of nonspecific defenses include physical barriers like the skin, mucous membranes, and cilia in the respiratory tract, as well as chemical defenses such as enzymes, antimicrobial proteins, and inflammatory responses.
On the other hand, specific defenses, also known as adaptive or acquired defenses, are developed by the immune system in response to a particular pathogen. These defenses are highly specialized and tailored to target specific pathogens, and they have the ability to "remember" the pathogen and mount a stronger and more specific response upon re-exposure. Specific defenses are mediated by immune cells such as B cells and T cells, which can recognize and respond to specific antigens, which are unique molecular markers on pathogens.
By categorizing the immune system into nonspecific and specific defenses, we are able to differentiate between the immediate, general responses of the immune system (nonspecific defenses) and the highly specialized, targeted responses that are developed over time (specific defenses) to effectively combat different types of pathogens. This classification helps us understand the complex and dynamic nature of the immune system and how it functions to protect the body from harmful invaders.

Decomposition is a crucial step in the cycling of carbon, nitrogen, and phosphorus.
Decomposition is the breakdown of organic matter into more easily digested inorganic substances such carbon dioxide, water, nitrogen, and phosphorus by bacteria and fungi. The plants can then absorb these inorganic substances and employ photosynthesis to create new organic stuff.
Because it releases nutrients that were bound up in organic matter back into the soil, so they can be absorbed by live plants and recycled through the food chain, decomposition is an essential process in natural ecosystems.

A species of moth has a 2 varieties of wing color: brown and white. As winter approaches, the trees where the moths live loose their leaves. The moth's predators are birds who hunt for the moths as they rest on the dark tree bark. Every moth lays 100 eggs, but only about 10 from each egg cluster live to adulthood.
How does this species overproduce and how will this species change overtime?
The species of moth overproduces since only a small percentage of the 100 eggs laid by each moth that hatch into adult moths. This indicates that there is fierce rivalry among the offspring for food and to survive against predators like birds.
Predators would be able to spot the white-winged moths more readily on the black tree bark in the winter because of the loss of leaves, whereas the brown-winged moths could blend in better and be less noticeable. Therefore, there would be a greater possibility for the brown-winged moths to live and pass on their genes to their progeny.
