If Plant A with yellow flower (dominant trait) is crossed with Plant B white flower (recessive trait), what is the percentage of the offspring having a yellow flower? Plant A: YY Plant B: yy
Answers
Answer:
100%
Explanation:
Yellow flower color (Y) is dominant over white flower color (y). Plant A is YY while plant B is yy:
YY x yy
Yy Yy Yy Yy
All the offspring would have Yy genotype and since Y is dominant over y, all of them will have yellow flower color as opposed to while.
Hence, the percentage of the offspring that will have a yellow flower would be 100%.

In the Linnaean system of classification, camels are members of the order Artiodactyla and the family Camilidae. Llamas are also members of
the family Camilidae. Based on this information, are llamas members of the order Artiodactyla?
а No, because every family member is classified into a different order.
b Maybe, because families and orders are separate and unrelated taxa.
с Maybe, because some but not all family members are classified in the same order.
d Yes, because all family members are classified together in the same order.
Answers
Answer:
The correct answer is - Yes, because all family members are classified together in the same order.
Explanation:
In the Linnaean system of classification, there are 7 taxa that are kingdom, phylum or division, class, order, family, genus, species. In these taxa, the kingdom is most inclusive and species is least inclusive taxa.
Order is more inclusive than the family which means various organism families make the order. If a family all the members are classified under the same order. Order have different families and each family have a different genus and so on.
Why does the major driver of plant adaptations vary so much over the surface of the moutain
Answers
Mountain ecosystems are particularly vulnerable to climate change because of the very specific adaptations and small ecological niches of species.
Which make it possible for even minor environmental changes to cause a re-assemblage of species communities. Mountain ecosystems are also particularly small and limited in scope, have a tendency to fragment, and are physically isolated from other mountain ecosystems.
The possible benefits of climate change for vegetation include extending the growing season, but these apparent advantages may be outweighed by detrimental impacts on growth and reproduction brought on by, for example, increased frost damage or decreased snowpack. The difficulties of tree seedling establishment at high elevations brought on by night frosts, fires, and severe radiation reduces the upslope migration of treeline.

Independent and dependent variables
Answers
Answer:
Independent variable: The amount of fertilizer.
Dependent Variable : The amount of water, the amount of soil. amount of sun light.
Explanation:
I can't really explain it but I am pretty sure that is the right answer. Hope it helps :)
Independent variable: The amount of fertilizer and Dependent Variable : The amount of water, the amount of soil.
What are dependent variable?In an experimental study, an independent variable is one that you change or alter to examine its effects. It is named "independent" because it is unaffected by any other study variables.
Other names for independent variables include: determinant variables (they can be used to predict the value of a dependent variable). Right-side parameters (they appear on the right-hand side of a regression equation).
These phrases are particularly useful in statistics, where you evaluate how well a change in one independent variable can account for or anticipate changes in another.
Therefore, Independent variable: The amount of fertilizer and Dependent Variable : The amount of water, the amount of soil.

The mayor is deciding whether to have a coal-fired power plant or a nuclear power plant in his town. As a member of his team, describe the advantages and disadvantages of each.
Answers
Answer:
Coal-fired power plants and nuclear power plants have their own advantages and disadvantages. Coal-fired power plants are generally considered safer than nuclear power plants because a coal power plant's failure is not likely to cause catastrophic events such as a nuclear meltdown would². Coal-fired power plants are also more reliable than nuclear power plants because coal's ability to supply power during peak power demand either as base power or as off-peak power is greatly valued as a power plant fuel³. Additionally, coal-fired power plants are more affordable, abundant, and have known technologies². However, coal-fired power plants produce more outward radiation exposure than a nuclear power plant would produce¹. The emissions are also linked to increased levels of asthma and lung cancer for local populations compared to other forms of energy¹.
On the other hand, nuclear power plants are cleaner and more efficient than coal-fired power plants because they do not produce greenhouse gases or air pollutants¹. Nuclear power plants also have a smaller footprint than coal-fired power plants and can produce more energy per unit of fuel¹. However, nuclear power plants are more expensive to build and maintain than coal-fired power plants². Nuclear power plants also pose a risk of nuclear accidents and the disposal of nuclear waste is a major environmental concern¹.
It is important to note that both coal-fired power plants and nuclear power plants have their own advantages and disadvantages. The decision to choose between the two depends on various factors such as cost, reliability, safety, environmental impact, and energy efficiency.

Answers
The inheritance of wheat kernel color shown in Figure 14.21 is an example of multiple allelism. This is because there are more than two possible alleles that can determine the kernel color.
In this case, there are three alleles: P1, P2, and P3. Each allele can produce a different amount of pigment, resulting in different shades of kernel color. This type of inheritance is different from codominance, where two different alleles can both be expressed equally, or from polygenic inheritance, where multiple genes contribute to a single trait.
Additionally, this is not an example of linkage, where genes that are physically close together on a chromosome tend to be inherited together. Therefore, multiple allelism is the best explanation for the inheritance of wheat kernel color shown in Figure 14.21.

Relying on the situation, oil spills may be very harmful to marine birds, sea turtles, and mammals, and also can damage fish and shellfish. Oil destroys the insulating capacity of fur-bearing mammals, which include sea otters, and the water-repelling abilities of a bird's feathers, exposing them to tough factors.
Oil spills can damage sea creatures, destroy an afternoon at the beach, and make seafood hazardous to consume. It takes sound technological know-how to ease up the oil, measure the effects of pollutants, and help the ocean recover.
Oil spills frequently show up because of injuries, when people make mistakes or equipment breaks down. other causes consist of natural screw-ups or deliberate acts. Oil spills have essential environmental and monetary outcomes. Oil spills also can have an effect on human health.

Since cyanobacteria do not contain chloroplasts and yet they photosynthesize, chloroplasts are not required for photosynthesis.
True or False?
Answers
Since cyanobacteria do not contain chloroplasts and yet they photosynthesize, chloroplasts are not required for photosynthesis, the given statement is true because chloroplasts and cyanobacteria are capable of carrying out photosynthesis
Cyanobacteria possess photosynthetic pigments called phycobilins and chlorophyll, which are embedded in their cell membrane within structures called thylakoids. These thylakoids perform the same function as chloroplasts do in plants and algae, capturing light energy and converting it into chemical energy through the process of photosynthesis.
Chloroplasts are organelles found in plant and algal cells that are believed to have evolved from cyanobacteria through endosymbiosis, where one organism lives inside another. In this case, a cyanobacterium was engulfed by a eukaryotic cell, forming a symbiotic relationship that led to the development of chloroplasts. In summary, the given statement is true because although chloroplasts are not present in cyanobacteria, these organisms still perform photosynthesis using their thylakoid membrane structures. This demonstrates that chloroplasts are not required for photosynthesis, as the key components for this process can be found in other cellular structures.
