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.

2. It collects information from the sense organ such as the eyes and the nose. c. peripheral nervous system
3. It serves as the primary organ of the central nervous system. f. spinal cord
4. It controls or regulates the body's internal brain environment, including the body temperature, pulse and respiration rate, and bood pressure. e. autonomic nervous system
5. It is one of the systems that is directly involved in maintaining the normal functions of cells. d. nervous system
Explanation:
Neuron: Neurons are the structural and functional units in the nervous system. Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites that are cytoplasmic extensions that receive stimuli from other cells, and an axon that is a long formation capable of conducting the electrochemical signals. Every neuron forms connections with other neurons. These connections are known as synapsis.
Peripheral nervous system: Sense information is received by the peripheral nervous system and processed by neurons and synapses in the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons.
Spinal cord: The nervous system might be divided into the central nervous system and peripheral nervous system. There are two organs involved in the central nervous system that funtion as control centers. One of them is the brain, and the other organ is the spinal cord, surrounded by the vertebral column.
Autonomic nervous system: The autonomic nervous system is conformed by the sympathetic nervous system and the parasympathetic nervous system. It has too many functions in the organisms, controlling pressure, heart bitting, body temperature, sexual responses, urination, digestion, general metabolism, among others. It controls and regulates the whole organism.
The nervous system: Homeostasis refers to stability, balance, or equilibrium. The organism needs to maintain homeostasis to guarantee the correct functioning of cells, tissues, organs, and so on. The homeostatic regulation is controlled by the endocrine system and by the nervous system, which acts as the control center.
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.

what does the number of protons in an atom determine about the atom?
Why is Glycolysis also known as Alcoholic or lactic acid Fermentation?
Answer:
In lactic acid fermentation, pyruvate from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells. In alcoholic fermentation, pyruvate changes to alcohol and carbon dioxide. This type of fermentation is carried out by yeasts and some bacteria.
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.
What gametes are produced by the following organisms:_______.
a. Genotype YyRr, if Y and R are on different chromosomes
b. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over
c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
Answer:
The correct answer would be -
1- YR, Yr, yR and yr.
2. Yr, yR
3. YR, yr
4. YR, Yr, yR & yr
Explanation:
A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.
The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.
1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.
2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.
3). if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.
4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.
Identify the relationship described below:
Killer whales, also known as orcas, hunt and eat numerous other organisms — more than 140 species. However, orcas themselves are not hunted by any other organism. In other words, they are at the top of the food chain.
Group of answer choices
Mutualism
Parasitism
Commensalism
Competition
Predator-Prey
hi :)
The relationship described is predator-prey.
The orca is hunting and eating other organisms, which is known as a predator-prey relationship.
In case you need help with any more of these-
Mutualism is when both animals get something out of the relationship, for example, some kinds of shrimp get the food out of fishes teeth. The fish gets clean teeth, and the shrimp gets a meal.
Parasitism is fairly self-explanatory. This is when a parasite lives and gains from a host, while the host is harmed and could get diseases from the parasite.
Commensalism is when one animal benefits and the other isnt harmed nor benefited. An example of this is the remora fish which clings to the bottom of other fish when it gets tired.
Lastly, Competition. This is when two organisms compete for something they need to survive. For example, two lions could compete for a food source, such as a zebra. Usually, the strongest and fastest organism survives, or wins.

After a successful launch and return of a rocket, NASA and SpaceX noticed a strange gel like substance on the wing. Under the microscope the strange thing has fibers, but no cells. When introduced to water the substance tends to move around. When exposed to warm temperatures it seems to grow in mass.
nonliving the heat from the hot plate is causing the gel like substance to move it's the same thing with liquid nitrogen how it seems to bounce off the floor it's because liquid nitrogen is super cold and the heat basically excites the electrons in the liquid nitrogen making it bounce off the floor same with the gel like substance the electrons in the gel substance are getting excited by the heat and jumping up and down but the substance itself is not alive

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.

The final paragraph of the CNN report said that "several eye specialists" had pointed out that the study should have accounted for heredity. Myopia is passed down from parents to children. Myopic parents are more likely to have myopic children, and may also be more likely to leave lights on habitually (since the parents have poor vision). In what way does the knowledge of this possible genetic link affect how we interpret the data from the study? Explain.
Answer:
Myopia is a phenotype that results from interactions between genetic factors and the environment
Explanation:
A quantitative trait is a polygenic trait that depends on the cumulative effects of many genes and the environment. Some examples of quantitative traits include weight and height. Myopia is a quantitative trait whose phenotype depends on the combined action of different genes and the environment. It has been shown that genetics plays a central role in this trait (myopia), it is for that reason that myopic parents are more likely to have myopic children. However, there also are environmental factors (e.g., diet) which increase the risk to suffer myopia.

Do green leaves absorb the maximum amount of light? If not, what color of leaf would
absorb more light?
Answer:
Chlorophyll a is the chief pigment associated with photosynthesis. As we can see,chlorophyll a absorbs red and blue wavelengths to a higher extent. Green light isn't rejected but rate of photosynthesis is more with red and blue wavelengths of light.
Explanation:
The spectral absorbance of photosystems and chloroplasts is lowest for green light...
All plants, however, has chlorophyll a, which absorbs most strongly at ~450 nm, or a bright blue color.
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.
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:
