Answer:
B
Explanation:
The only reasonable alternate conclusion that can be drawn from Masha's data is that the bees frequented the daisies the most because daisy pollen has an odor that is attractive to bees.
The conclusion is the only one that suggested an alternate reason that is compatible with the trend observed in the data.
Concluding that the bees frequented the daisies because they are unable to see the color white is erroneous because the bees could not have visited the daisies without the ability to see color white. If the bees were also most attracted to the color yellow, they should have visited the sunflower the most.
The correct option is B.
Answer:
B. Bees frequented the daisies the most because daisy pollen has an odor that is attractive to bees.
Explanation:
Scientists have differing opinions and interpretations when it comes to producing results for experiments. This creates the variety in science that springs up new investigations and experiments.
Marsha claimed that bees frequented the daisies because they are attracted to the color of the flower. An alternate explanation for why bees frequented daisies could be because daisy pollen has an odor that is attractive to bees.
Since daisies are white, it does not make sense to say that bees cannot see the color white. The explanation that bees frequented the daisies the most because they prefer the color yellow also is not reasonable because they would likely have visited the sunflowers the most if this were the case.
Goats can either be polled or horned. The pulled, or no horn, trait (P) is dominant to the horned (p) trait. Another trait in goats are wattles, which are hair covered structures on their necks. Even though most goats do not have wattles, having wattles (W) is dominant to not having wattles (w). A breeder crosses a polled, wattled male goat with a polled, wattled female goat. Some of the offspring have horns and no wattles. Perform a cross of the parental genotypes to find the phenotypic ratios of the offspring.
Answer:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
Explanation:
Pulled = P, Horned = p
Wattled = W, no wattle = w
Polled, wattle goats = P_W_
Since they produced offspring with horns and no wattles (ppww), it means both parents have the recessive allele for each trait. Hence, they are both heterozygotes with PpWw as genotypes.
PpWw x PpWw
Genotypes ratio of the offspring:
P_W_ - 9/16
P_ww - 3/16
ppW_ - 3/16
ppww - 1/16
Phenotype ratio of the offspring:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
(See the attached image for the Punnet's square)
Some alleles of a gene are dominant to others masking the effect this other alleles.
The polled, or no horn, trait (P) is dominant to the horned (p) trait.
Having wattles (W) is dominant to not having wattles (w).
A breeder crosses a polled, wattled male goat with a polled, wattled female goat.
The phenotypic and genotypic ratios would be
Polled and wattled = P_W_ = 9/16Polled with no wattle = P_ww = 3/16horned and wattled = ppW_ = 3/16horned with no wattle = pwpw = 1/16Parent genotype --- polled, wattled male and female goat -- P_W_
As the cross produced offspring with horns and no wattles (ppww), it shows both parents have the recessive allele for each trait.
Hence, they are both heterozygotes with PpWw for the traits.
Parent genotypes: PpWw x PpWw
PW Pw pW pw PW Pw pW pw

Explanation:
Animals and plants use the chemical energy stored carbohydrates to fuel their own life processes, ultimately breaking down these carbohydrates into carbon dioxide, water, and heat in a process called aerobic respiration. The heat that is released from aerobic respiration dissipates into the environment. From this information, which of the examples of kinetic energy are:______
Answer:
A good example happens during the breakdown of food particles.
Explanation:
The chemical energy stored in food is a type of potential energy. Transformation of this energy into kinetic energy happens during chemical reactions that takes place during digestion. A good example of kinetic energy is therefore the breakdown of carbohydrates into carbon dioxide, water and heat.

Explain whether an experiment or an observational study would be more appropriate to investigate whether meditation is effective in lowering blood pressure.
Answer:
Experiment.
Explanation:
An experiment would be more appropriate method to investigate whether meditation is effective in lowering blood pressure because experiment has a control group as well as a testable group. Due to control group and testable group, we can easily find out the effect of meditation in lowering blood pressure if we apply meditation techniques to the testable group and compared it with the control group, we get results.

1.Paramecium was found to occupy 20% of the FOV of a microscope at 40X magnification power. How many paramecium can be accommodated within this FOV
Answer:
Five (5)
Explanation:
A total of five (5) paramecia can be accommodated within the FOV.
The field of view of a microscope represents the area of the visible region under the ocular/eyepiece at a specific magnification. In other words, the diameter of the circular area visible through the ocular of the microscope at a specific magnification represents the field of view.
If a paramecium was found to occupy 20% of the total field of view of a microscope at X40 magnification, then the total number of paramecia that can be accommodated within the field would be:
100/20 = 5 paramecia
The number of many paramecium can be accommodated within this FOV
is Five (5)
Given that,
Paramecium was found to occupy 20% of the FOV of a microscope at 40X magnification power.Based on the above information, the calculation is as follows:

in what ways can overpopulation be beneficial to differential reproductive success?
Answer:
Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.
Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2.
Answer and Explanation:
Petroleum and coal are fossil fuels. The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.
