Answers
Answer:
75%
Explanation:
The allele for purple flowers (capital P) is dominant.
The allele for white flowers (lowercase p) is recessive.
If one allele is capital P, it doesn’t matter if the other allele is another capital P or a lower case p, the capital P will dominate and purple flowers will show up.
The Punnett Square shows:
PP, Pp, Pp, and pp
• 3 of the offspring have at least one dominant and capital P, so purple flowers show up.
• 1 of the offspring has two lowercase and recessive alleles (p), so white flowers show up.
3/4 or 75% of the offspring will have purple flowers.
[tex]\huge\boxed{Option A}[/tex]
_____________________________________ PEA PLANT:Pea plant has purple color flowers dominant over white color flowers.
Purple flower dominant allele is P
White Flower recessive allele is p
We would get White flower pea plant only when the recessive allele is in HOMO.ZYGOUS condition
_________________________________________________________
CONDITIONS:Hom.ozygous Dominant Alleles: PP (Purple Flower)
Heter.ozygous Dominant Alleles: Pp Purple Flower)
Hom.ozygous Recessive Alleles: pp (White Flower)
____________________________________ CROSS:Whenever we cross Heterozygous Dominant(Pp) purple flower with another Heterozygous dominant (Pp purple flower), we get 75% of the flowers PHENOTIPICALLY(physical appearance) white flowered, and 25 white flowered Because as you can see in the picture,
The P1 is Pp
The P2 is Pp
When we cross them,
It has 4 offsprings,
PP Hom.ozygous Purple flower
Pp Heterozygous Purple flower
Pp Heterozygous Purple flower
pp Hom.ozygous white flower
Thus the answer is 75% as there are phynotypically 3 purple flowers present

a) eyes and lungs
b) ear and throat
c) eyes and nose
d) lungs and heart
Answers
Answer:
lungs and heart
Explanation:
lungs and heart is the answer because human lungs is use for gas exchange during respiration or while you breathe. When humans breathe, the lungs absorb oxygen from the inhaled sir into the blood and carbondioxide leaves the blood when we breathe out. The heart pumps the blood, and oxygenated blood are carried in the blood when air is inhaled and carbondioxide leaves the blood when you exhale. The blood carries nutrients and oxygenated blood. Therefore, lungs and heart work hand in hand in absorbtion of oxygen from it's environment.

Answers
Answer:
from deepest to shallowest, the inner core, the outer core, the mantle and the crust.
Explanation:
Starting deep in the center, the correct order of the earth's layers is the inner core, mantle, and outermost crust, where the inner core has a higher temperature and pressure than other layers.
What is the earth?The earth is made up of a core, a mantle, and the outermost crust, where the core has a large pressure and, despite the high temperature, the substance remains solid in nature, and on the crust region, the lithosphere is present, such as the mountains, water bodies, etc. The earth has atmospheric layers, which are further subdivided into the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, and each layer has its own properties, such as the ozone layer in the stratosphere. Life is abundant on earth as a result of all of these favorable conditions.
Hence, starting deep in the center, the correct order of the earth's layers is the inner core, mantle, and outermost crust.

disease
The factors that will affect a population regardless of population density is flooding. The correct option is C.
What is population?A population is the entire group about which you want to draw conclusions. A sample is the specific group from which you will collect data.
The sample size is always less than the total population size. A population for this research does not necessarily refer to people.
A population is a subset of individuals from one species that live in a specific geographic area and interbreed in reproducing species. Some species' geographic boundaries are easy to establish, while others are more difficult.
Population change is influenced by three factors: birth rate, death rate, and migration. Though one or two of these factors may have an impact on a population in a specific area, all three have an impact on population change.
Thus, the correct option is C as the population can be get affected by flooding without regarding their density.

Which statement describes how heat flows from the coffee to the part of the spoon in the coffee?
Heat flows from the coffee to the spoon through radiation.
Heat flows from the coffee to the spoon through convection.
Heat flows from the coffee to the spoon through conduction.
Heat flows from the coffee to the spoon through radiation, convection, and conduction.
Answers
Answer:
C. Heat flows from the coffee to the spoon through conduction.
The heat movement known to move from one area to elsewhere has been called heat transfer. Thermal conduction allows the coffee's heat to reach the spoon. Thus, option C is correct.
What is thermal conduction?A type of heat transfer called thermal conduction occurs when heat flows from one spot to some other place due to the disparity in temperatures between the bodies.
When a body is subjected to thermal conduction, heat energy is dissipated from the body towards the colder or less heated objects. Because the spoon and coffee are at different temperatures, the heat from the coffee is passed to the spoon through conduction.
Therefore, thermal conduction is the process through which the coffee heats the spoon in the cup.

10 POINTS !!! Why is it risky to build something whose natural frequency can be matched by
external vibrations?
Answers
Answer:Most objects have at least one natural frequency of vibration. If a nearby object vibrates at the same frequency, it can cause resonance. Resonance is an increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
Explanation:
It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance
When an object constructed has a natural frequency which is equal to the frequency of a nearby external vibration, the amplitude of the vibration of the object will increase due to the resonance effect which occurs because the external frequency matches up with the natural frequency of the constructed object.
The negative effect of resonance is the increase in the amplitude of the vibration of the object which might lead to the partial or complete collapse of the constructed object.
Hence we can conclude that It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance

Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interference (both retroactive and proactive).
Answers
Answer:
Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.
