Answer:
Not necessary.
Explanation:
No need for the revision of big band theory because this galaxy may be a product of big band event. At the start this galaxy is shorter and hot but with the passage of millions of years, this galaxy also expands and formation of stars and planets occurs. The stars and planets that are present in the galaxy occurs due to different events that is responsible for their current conditions. This formation of stars and planets needs millions of years.

Most of the coal found on Earth today was formed during the Carboniferous and Permian Periods. About how old could a piece of coal be?
Answer: 298.9 million years old
Explanation: hope it helps luv ❤✨
A piece of coal would be 298.9 million years old. This is because the Permian period was initiated approximately 298.9 million years ago.
What are the characteristics of coal?The characteristics of coal are as follows:
It primarily consists of carbon, hydrogen, and oxygen.It contains a very less amount of sulfur and nitrogen.It is black in color and has a metallic luster.It is significantly hard as stone. Coal is widely utilized in power plants in order to generate electricity.According to ancient tomes and periods, the Permian period ends about 252.2 million years ago and it was the time of the initiation of the carboniferous period that further extends to the Triassic period. This was all about the time duration when the first piece of coal was found in the atmosphere.

On the planet Fugus, there is a species of flowers, Dontdrinkmycola, that has two special loci: Bach01 and Bach02. At Bach01, there are two alleles in the population: A (dominant) and a (recessive). Similarly, at locus Bach02, there are two alleles in the population: B (dominant) and b (recessive).
Individuals with the A_ genotype at Bach01 have mauve colored petals, and individuals with the aa genotype have teal colored petals. Likewise, individuals with the B_ genotype at Bach02 have mauve colored petals, and individuals with the bb genotype have teal colored petals.
In a cross between two doubly heterozygous Dontdrinkmycola flowers, the following number of offspring are produced: 280 offspring with mauve colored petals, and 220 teal-colored petals. The most likely form of epistasis here is:
a. Duplicate dominant epistasis.
b. Dominant recessive epistasis.
c. Duplicate recessive epistasis.
d. Recessive epistasis.

Compare and contrast point mutations and chromosomal mutations. Which part of the organism's DNA is affected as a result of each?
Answer:
In point mutation,the gene is affected however in chromosomal mutations,there is change in the structure or number of the chromosomes
The primary distinction among point mutation and chromosomal mutation is, the point mutation is a small mutation in which basically a single base pair of the either DNA or RNA encoding changes, whereas chromosomal mutation is a large-scale mutation in which the chromosome structure changes.
What is mutation?A mutation is an alteration in an organism's DNA sequence. Mutations can take place as a consequence of mistakes in DNA replication during cell division, mutagen exposure, or viral infection.
Mutagens are environmental factors that results in mutations. Mutagens can be either radiation, chemicals, or infectious agents.
In living organisms, there are two kinds of genetic mutations namely point mutation and chromosomal mutation.
The nucleotide sequences are usually altered in both cases. As a result, all these types of mutations can result in fatal diseases.
The main difference between point mutation and chromosomal mutation is that point mutation is a small-scale mutation that changes a single base pair of the DNA or RNA encoding, whereas chromosomal mutation is a large-scale mutation that changes the chromosome structure.
Thus, this is the comparison between the types of mutation.

What is some evidence that makes plate tectonics is such a firmly believed idea?
Answer:
There are many shreds of evidence that support the theory of plate tectonics and make it such a firmly believed idea. These pieces of evidence include fossils, glaciers, earthquakes and volcanic activity, the shape of continents, the magnetism of rocks on the seafloor, the mid-ocean ridge system, and others.
Fossils give an idea of the location of the plants and animals that once existed. Earthquakes and volcanic activity also help in determining the cause of the boundaries and rifts formed. The shape of the continents seems to be fit with one other that gives the idea that these were together and moved away from each other.

If glucose is metabolized under completely anaerobic conditions, pyruvate ( Please explain why each answer is wrong or right.)
a. immediately enters the Krebs cycle.
b. is converted by fermentation to lactate or CO2 and ethanol.
c. is converted back to fructose until the concentration of oxygen increases.
d. is converted to NADH.
Answer:
B.
Explanation:
A is wrong because pyruvate would enter the Krebs cycle under aerobic condition (when oxygen is present). Hence the name aerobic cellular respiration
C. I do not really too much about fructose or the concentration of oxygen, but I can assure that this answer choice is not correct.
D is wrong because NADH would be converted from NADP+. Either with oxidation or reduction, and this helps to keep this process going.
B is correct because fermentation is another word for anaerobic cellular respiration. The process takes place with the absence of oxygen. It either goes through Alcoholic or lactic acid fermentation.

factors that affect rate of erosion
Answer:
farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.
Explanation:
Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.
The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.
Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.
Other factors that affect the rate of erosion in an area include the following; farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.
