Explain how this experiment disproves the theory of spontaneous generation.
Answer:
The theory of spontaneous generation suggested that the living organisms can come from inanimate objects, however, it is an obsolete theory that is disproved by many experiments. The very first experiment that disapproved it was the experiment by Francesco Redi in 1668.
He demonstrated that maggots come from the eggs of flies instead of rotting meat. He placed raw meat inside of every jar. Half the jars he left open and the other half, he covered with mesh. In open jars, he found maggots after some time but covered jars have no maggots. That proved that the maggots come from eggs of flies rather than rotten meat.
The presence of flies on the meat is responsible for the production of maggots in meat.
This experiment disproves the theory of spontaneous generation because maggots are produced from the flies not the rotten meat. According to spontaneous generation, living organisms are formed or develop from nonliving matter.
So by performing this experiment we can see that maggots are formed when the flies feed on the rotten meat otherwise no maggots are present if the flies are not present there so that's why we can conclude that this experiment rejects the theory of spontaneous generation.

Choose the FALSE statement about the space shuttle program. A. It lasted over 30 years. B. It launched the Hubble Space Telescope. C. It conducted scientific experiments in lunar orbit. D. It helped in the creation of the International Space Station.
The space shuttle can only get as high as the low-earth orbit (LEO). This is a few hundred or so miles within the earth's surface. Compare this to the distance from the earth's surface to the moon is about 238,855 miles on average.
According to NASA's website: "It does not carry enough propellant to leave Earth's orbit and travel to the Moon. The Space Shuttle also is not designed to land on the Moon since it lands like an airplane and the Moon has no atmosphere"
Would you expect the plants and animals present in the southeast of the U.S. To be similar or different to that of the plants and animals present in Northeast Africa?
Answer:
Different
Explanation:
The climatic conditions or weather conditions of the southeast of the United States are different to that of the northeast Africa. And because of this, the two zones are not expected to have the same type of animals.

Which is one way that minerals crytallize from materials dissolved in water
From the air
From solutions that evaporate
From hot water solutions when water boils
From the soil
Answer:
From solutions that evaporate
Explanation:
Minerals can form in different ways. According to the question, minerals crystallize from a material dissolved in water when the solution evaporates. When a material dissolves in water, it forms a solution i.e. water + dissolved material.
The element constituents of the solution can aggregate to form a solid mineral, which will be left to crystallize when the solution undergoes evaporation i.e. liquid changes to gas. A very good example is when salt dissolves in water to form a salt water solution. When the water of this solution evaporates, salt crystals are left, which can crystallize to form minerals.
Answer:
From solutions that evaporate

(1) What will be the frequency of the recessive allele in a population of 100 kangaroos if there are 50 dominant alleles?
a. 150
b. 0.75
c. 0.50
d. 0.25
(2) If the frequency of the recessive allele for a gene is 0.3, calculate the expected frequency of heterozygotes in the next generation if the population is in Hardy-Weinberg equilibrium.
a. 0.42
b. 0.21
c. 0.70
d. 0.30
Answer:
1. Option c
2. Option a
Explanation:
1. If there are 50 dominant alleles, this represent the frequency of dominant alleles p = 50/100 = 0.5
Using the formula p+q = 1 we can solve for the frequency of the recessive alleles q = 1 -0.5 = 0.5 = 50%.
2. the frequency of the recessive allele for a gene is 0.3 which is q = 0.3
From the Formula p + q = 1 we can solve for p the frequency of the dominant alleles = 1 - 0.3 = 0.7
To calculate for the number of heterozygotes, we use 2pq = 2 x 0.7 x 0.3 = 0.42
Is it recommended for most adults that carbohydrates make up 45-65% of their diet, proteins make up 10-35% of their diet, and fats make up 20-30% of their diet. Does Deb’s diet mee these recommendations? Support your statement with calculations
Answer:No her diet does not. She is currently eating 128.52 calories each for protein, 289.17 calories from fat, and 1413.44 calories from carbs. This means she is consuming 6.6% of her diet from protein, 14.9%, of her diet from fat, and 73.2% of her diet from carbs.

What might happen to the organisms in the food web below if the number of phytoplankton and vegetation drastically decreased?
Answer:
i don't now exactly how to answer this when theres' no food chart however as the vegetation and phytoplankton drastically decrease everything decreases. This is because the producer the bottom of the food chain also known as vegetation is the prime source of energy in every food chain. when there's scarce amounts of producers a domino affect will occur. There will be no food for the first consumers to eat leading their population to decrease and the animals that feed off them will decrease then the animals that feed of them will decrease and so on until the organisms of the food web die out.

Look at the following mutation: AUG-GUC-CCU-AAA → AUG-AGU-CCC-UAA-A. The base A was inserted following the start codon AUG. Describe how this mutation affects the encoded amino acid sequence.
Answer: Non sense mutation took place over here.
Explanation:
Mutation took place over here where, the base A was inserted in place of the start codon AUG.
This states that the last codon will code for a stop signal instead of amino acid.
This is a type of non sense mutation when the ribosome is stopped from reading a stretch of mRNA because a stop codon is present over there.
The original set of codon is replaced by the stop codon and the protein synthesis is stopped.
When there is an alteration in the genetic bases of codes that can lead to modification in the phenotype or the genotype of an organism is called a mutation.
The type of mutation that occurred in the given sequence is a non-sense mutation.
The mutation can be explained as:
The mutation changed the reading frame of the triplets from the second place after the AUG or the start codon.The last codon in the unmutated sequence AAA was for lysine (lys) but in the mutated sequence is changed to UAA (stop codon) which codes for the termination of the chain.The mutation in stop codons are called non-sense mutation and now it will signal for termination instead of coding for another amino acid.When the process of translation gets terminated and the ribosomes stop translating due to mutation then it is called a nonsense mutation.Therefore, the process will terminate due to replacement by a stop codon.

Why are human populations not limited by the carrying capacity of their ecosystems?
Answer:
humans use their knowledge to locate resources.
Explanation:
The carrying capacity can be defined as the maximum number of individuals in a population of a species that an ecosystem or region can support on the basis of availability of water, food, habitat and other needs necessary for survival. Sometimes, the population of the species increases exponentially exceeding the carrying capacity of an ecosystem when the resources available are surplus.
The human populations are not limited by the carrying capacity of their ecosystem this is because of the fact human beings possess special intellectual and thinking abilities which make them capable of availing themselves resources. They posses knowledge which allows them to search, and find resources even from the earth extreme locations not suitable for survival.

Mutation may occur in gametes or in body cells. In which cell type is a mutation likely to be source of genetic variation for ?
Answer:
Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN (genotipo) de un ser vivo,1 que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos. Este cambio estará presente en una pequeña proporción de la población (variante) o del organismo (mutación). La unidad genética capaz de mutar es el gen, la unidad de información hereditaria que forma parte del ADN.2
En los seres pluricelulares, las mutaciones solo pueden ser heredadas cuando afectan a las células reproductivas.3 Una consecuencia de las mutaciones puede ser, por ejemplo, una enfermedad genética. Sin embargo, aunque a corto plazo pueden parecer perjudiciales, las mutaciones son esenciales para nuestra existencia a largo plazo. Sin mutación no habría cambio, y sin cambio la vida no podría evolucionar.

What is a good property of an indicator?
Answer:
Acid base indicators are weak and acids and bases, which are used to signify the end point of neutralization reaction. The type of indicator used for a neutralization reaction depends on the strength of the acid and the base, that are involved in the reaction. A good acid base indicator must have a good pH range and it must be able to produce specific and identifiable color in specific acid base medium.
or
Two good properties of an indicator are as follows-
1) It should be specific- It means that the changes, which are measured by the indicator should be expressed in precise terms so that appropriate assessment could be made.
2) It should be time bound- This means that the measurable changes should arrive withing a particular time limit.
Example of indicator- Litmus is an acid base indicator that turns acidic solutions red and basic solutions into blue color.
