how do tortoises differ among the galapagos islands? what causes these differences?
Answer:
How did tortoises and birds differ among the islands of the Galapagos? The tortoises on the Galapagos Islands all had different shaped shells; therefore they were different species of the same category of tortoises. ... Darwin found several types of small, ordinary brown birds.

Explanation:
Mutated codons code for what in silent mutations?
Answer:
Code for the same amino acid as the original codon
Explanation:
Mutation, which is any alteration in the nucleotide sequence of a gene, can occur when there is a replacement of base nucleotides. This is called SUBSTITUTION MUTATION. Substitution mutation can either lead to missense, nonsense or silent mutations.
As stated in this question, SILENT mutation is the one in which there is no change in the amino acid sequence after translation of the mutated mRNA. In other words, the mutation leads to an alteration of codon but the MUTATED CODONS CODE FOR THE SAME AMINO ACID as the original codon, hence, no effect on the protein produced or individual, in general.
The marine iguanas of the Galapagos Islands feed on seaweed and algae. Marine iguanas have flattened tails while other species of iguanas that live inland on the Galapagos and on the South American mainland have rounded tails. Which of the following best explains this difference in tail shape?
Answer:
Flattened tails are better for swimming than rounded tails.
The difference in the tail shape is because Flattened tails are better for swimming than rounded tails.
This is due to the difference in habitats of the marine and inland iguanas.Why do plants adapt for different habitats?This is due to natural selection.By natural selection, the nature of the species gradually changes to became adapted to the niche.To know more about natural selection here

Although the Cell Theory is widely accepted and well supported, what might happen to cause it change?
Answer:
By doing more research.
Explanation:
The cell theory change with the passage of time by doing more research about the cell. The final modification of the cell theory done by Rudolf Virchow in 1855 on the basis of his new research and findings about the cells. With the passage of time, modification occurs in microscope which enable the scientists to find different parts, organelles and features of cell on the basis of which scientists modify cell theory with the passage of time.
why are zebra mussels harmful to the lake
Answer:
The zebra mussels also outcompete the natives for food and space, and because of their fast reproduction can quickly overwhelm a water system.
Explanation:
The feeding habits of zebra mussels can also have a drastic impact on an infested lake. Zebra mussels are filter feeders that siphon particles of plankton from the water.

Answer:
Explanation:
Using its web as a gill, the diving-bell spider can live underwater with only occasional visits to the surface. The arachnid (Argyroneta aquatica) breathes air from a bubble that it grabs from the surface of water using fine hairs on its abdomen.

Answer:
Typically, the nucleus of a cancer cell is larger and darker than that of a normal cell and its size can vary greatly. Another feature of the nucleus of a cancer cell is that after being stained with certain dyes, it looks darker when seen under a microscope
Explanation:
In contrast to normal cells, cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumor. Cancer cells have more genetic changes compared to normal cells, however not all changes cause cancer, they may be a result of it.
3. What is the definition of recessive and dominant?
4. What is the difference between genotype and phenotype? Write a 5 sentence
paragraph describing the difference between the two.
Answer:
Recessive: relating to or denoting heritable characteristics controlled by genes which are expressed in offspring only when inherited from both parents.
Dominant: Refers to a trait that appears more frequently than another trait, resulting from interactions between gene alleles.
Explanation:
Genotype and phenotype differences
Genotype Phenotype
The hereditary information of the organism in the form of gene in the DNA and remains the same throughout the life. The characters of an organism which are visible are known as phenotypes.
Same genotype produces same phenotype. Same phenotype may or may not belong to same genotype.
Present inside the body as genetic material. Expression of genes as the external appearence.
The genotype is inherited from the parent to the offspring. The phenotype is not inherited from the parent.
It can be determined by scientific methods such as the polymerase chain reaction. It can be determined by observing the organism.
It is affected by genes. It is affected by genotype and environmental conditions.
For eg., Blood group, eye colour, height, genetic diseases. For eg., Weight, physique, beak of birds
In biological macromolecules like proteins, the hydrophobic residues tend to clump together in the interior of the folded structure. What is the best explanation for why this occurs
Answer:
The water and polar residues cannot bind to the hydrophobic ones, so in the lowest energy state the hydrophobic residues are pushed together in the middle.
What makes a species successful in an ecosystem?
Answer:
Beside the intensive loss of forest cover [2], fragmentation of the pristine remnants further affects species [3] and limits their ability to move into adequate areas. Thus the ability to cope with altered landscapes is crucial for the persistence of a species, especially in the face of climate change.

WHO HAS COMPLETED THE "Minerals and Earth's Natural Resources Quiz" IN USATESTPREP?
Answer:
Minerals are used in different products.
Explanation:
There are various types of minerals are present on the earth that are used in making of different products in industries. Iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium are the examples of minerals that are found in the soil of earth in large and lower quantity. Those minerals which is lower in quantity are highly costly while on the other hand, those minerals that are present in large quantity having lower prices. Earth's natural resources include air, water, soil, minerals, plants, and animals that make the ecosystem.

There is a species of frog on an island that puzzles scientists. The proportion of frogs with no stripes is greater than the proportion of frogs with
stripes. This is puzzling because the unstriped trait is recessive (s), and the striped patterns are due to dominant alleles (S). Also, natural selection
seems to support the striped trait.
How do genetic factors most likely account for the proportion of traits in the frog population?
A. Most of striped frogs and unstriped frogs have the genotype ss.
OB. Most of striped frogs have the genotype SS and the unstriped frogs have the genotype ss.
C. Most of striped frogs have the genotype SS and the unstriped frogs have the genotype Ss.
OD. Most of striped frogs have the genotype Ss and the unstriped frogs have the genotype ss.

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... Solids, liquids and gases all expand when heat is added.
Explanation:
Robert and his wife are ready to start a family, but they are concerned about having a child an inherited disease. This disease is a recessive disorder which requires both parents to contribute a recessive allele in order for the child to express the disorder. If both Robert and his wife are heterozygous for this trait, what is the probability that one of their children will have the disease?
The probability is 1/4
Both parents are heterozygous.
Aa + Aa
This will give the following possibilities for offspring genotype:
AA, Aa, Aa, aa
As you can see the chance of a offspring having 2 copies of the recessive allele (which is required for the offspring to have the inherited disease is only a 1 in 4 chance.

Discuss 3 different types of mutations that can happen
Answer:
Explanation:
Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.
