Answer:
Adenosine triphosphate (ATP) is an energy-carrying protein present in all living organisms' cells. ATP is a molecule that absorbs chemical energy from the degradation of food molecules and then releases it to power other cellular processes.

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.
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.

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.

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.

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.
What happens to the cells of a person who has cancer?
Explanation:
Cancer happens when cells that are not normal grow and spread very fast. Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don't die when they're supposed to.
Cancer cells continue to grow and divide out of control and don't die when they're supposed to.
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

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.
Which term represents animals without backbones?
invertebrates

The diving bell spider stores air underwater in a net of silk explain how this could be more advantageous than having gills
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.
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.

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

3. Synthesize in your own words, explain why scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity Refer to the Case Study.
Explanation:
Scientists give three reasons. First, amphibians are sensitive biological indicators of changes in environmental conditions such as habitat loss, air and water pollution, ultraviolet (UV) radiation, and climate change.Amphibians are sensitive biological indicators of environmental circumstances such as habitat loss, pollution of the air and water, ultraviolet (UV) radiation, and temperature change.
What is biodiversity?The variety and variability of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the genetic, species, and ecosystem levels is called biodiversity.
Biodiversity refers to the variety of all the diverse species of organisms that dwell on our planet, including the plants, animals, insects, and microorganisms.
Each of these things exists in a delicate balance and coexists with the others in ecosystems that nourish and sustain life on earth.
Amphibians are sensitive biological markers of changes in environmental conditions like temperature, UV radiation, habitat loss, and air and water pollution.
Thus, scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity.
