Answer:
Please find the explanation as to why Ravyn is albino when neither of her parents is abino below
Explanation:
According to Gregor Mendel in his law of dominance, a DOMINANT allele is a form of a gene (allele) that masks the phenotypic expression of another in a gene while the RECESSIVE allele is the allele being masked. This means that an allele can be present in a gene but in a masked or recessive condition.
According to this question, Ravyn happened to be an albino when neither of her parents is albino because BOTH of his PARENTS are HETEROZYGOUS for the skin color trait i.e. they both contain the allele for normal skin color, which is dominant, and the allele for albinism, which is recessive. Note that a recessive trait will only express itself when in a pure breed condition, hence, both parents contributed the reccesive allele (albinism) to produce the recessive condition in Ravyn.
In a nutshell, Ravyn is an albino because his parents are heterozygous and both passed on the recessive alleles to him.

Explain how PHOTOSYNTHESIS works in plants
Answer:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Explanation:
Which chemical bond most likely stores the most energy?
A. C=C
B. C-C
C. H-H
D. H-O
Answer:
The chemical bond which stores more energy is the Double carbon-carbon bond.

What else is produced during the combustion of propane, C3H8 is H20, but to understand this reaction, we need to know.....
Combustion of propaneWhen an oxidizer sold as a fuel, it is also called liquefied petroleum gas (LPG), which is a mixture of propane with small amounts of
PropyleneButane and butylene plus ethanethiolAs an odorant to prevent the normally odorless propane from going unidentified. when in leaks. It is used as fuel for stoves and in car engines.
The combustion of propane is a typically exothermic reaction with the evolution of heat:
C3H8 + 5 O2 → 3 CO2 + 4 H2O
With this information, we can say that the combustion product of propane is H2O.

How are chromosomes arranged in a karyotype?
Answer: A karyotype test examines these dividing cells. The pairs of chromosomes are arranged by their size and appearance.
Explanation:
In a karyotype, the arrangement of chromosomes is generally done in the order of size, that is, from largest to smallest.
What is a karyotype?It is the number and appearance of chromosomes. It comprises the length of the chromosomes, the banding pattern, and the position of centromere.
In a human karyotype, the body chromosomes or autosomes are usually aligned in approximate order of size from largest to smallest, that is, from chromosome 1 to chromosome 22.
However, the chromosome 21 is shorter in comparison to chromosome 22. The arms of the chromosomes protruding from either end of the centromere may be classified as long or short, based upon their relative lengths.
The long arm is abbreviated as q and the short arm as p. Each arm is subdivided further and is designated by a number. The locations on chromosomes can be illustrated by using the naming system.
Thus, in a karyotype, chromosomes are arranged on the basis of their size, that is, from largest to smallest.

What are weather and climate conditions?Weather is the collective name for the momentary properties of the lower atmosphere, including precipitation, temperature, humidity, wind speed, direction, and atmospheric pressure. The possibilities are endless: it may be bright, cloudy, rainy, foggy, chilly, hot, windy, stormy, snowy, etc.
Seasons, documented climate cycles, or volcanism are frequently to blame for short-term climate change, which affects shorter timescales.
Long-term climate change affects longer time periods and may be brought on by human activity, variations in the sun's output, or a sluggish recovery from the Flood.
Therefore, weather refers to atmospheric circumstances for a brief period of time, whereas climate refers to long-term, predictable atmospheric conditions.

Water that falls onto land surfaces is either soaked into the ground or flows downhill into a body of water. The water that soaks into the ground is called groundwater.
Soil and rock that allow this water to pass through them are called ________.
A. aquifers
B. compacted
C. permeable
D. runoff
The capacity of a rock or other substance to let the passage of water is known as permeability, hence option c is correct.
What is groundwater?Groundwater may readily flow through permeable materials because the pore space is linked throughout the rock or sediment. Mud and clay are examples of materials with great porosity yet very limited permeability.
An aquifer is a water-bearing rock that easily transfers water to wells and springs, the aquifers may be dug into and water pumped out.
Therefore, water that falls onto land surfaces flows into water bodies or it may be soaked in the ground, this water flows through the soil and rock which are permeable, hence option c is correct.

Are axolotl prokaryotic
Answer:
The axolotl, Ambystoma mexicanum, also known as the Mexican walking fish, is a neotenic salamander related to the tiger salamander. Although colloquially known as a "walking fish", the axolotl is not a fish but an amphibian. The species was originally found in several lakes, such as Lake Xochimilco underlying Mexico City. Axolotls are unusual among amphibians in that they reach adulthood without undergoing metamorphosis. Instead of developing lungs and taking to the land, adults remain aquatic and gilled.

A stone 'X' of mass 2 kg is at the height of 2 m from the ground level
Another similar stone 'Y' of mass 4 kg is at the height of 4 m from the ground
level. What is the difference between their potential energy?
un minutes Calculate
Answer:
120 joule.
Explanation:
Given
For the stone X
Mass (m) = 2 kg
Height (h) = 2 m
Acceleration due to gravity (g) = 10 m/s²
Then we have the formula to calculate the potential energy
P.E 1 = mgh
= 2 * 10*2
= 40 joule
Now for Stone Y
mass (m) = 4 kg
height (h) = 4 m
acceleration due to gravity (g) = 10 m/s²
Now
P. E2 = mgh
= 4 * 10* 4
= 160 joule
Now the difference between their potential energy is
= P. E2 - P. E 1
= 160-40
= 120 joule

What are the three main classifications that describe galaxies? By what one visible
characteristic do scientists categorize galaxies?
Answer:
Spiral Galaxies, Elliptical Galaxies & Irregular Galaxies
Explanation:
How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.
