Explanation:
If the amount of pollution is the same in the ocean where the fish are being caught, why
might some fish have more of this toxin than others?
Answer:
Because they might be taking in a higher concentration of the toxin through food or their environment or others could just be older meaning theyve ingested more of the toxin overtime
Explanation:
The level of toxin in fishes that lives in the area of the same pollution may differ due to the ability to consume toxins.
What do you mean by Toxins?Toxins may be defined as a poisonous substance that is a specific product of the metabolic activities of a living organism and is usually very unstable, notably toxic when introduced into the tissues, and typically capable of inducing antibody formation.
While living in the area or habitat of the same pollution, still some fishes have more of this toxin than others. This is because these fishes have the ability to consume toxins from food resources that are present in the same habitat. While some fishes consume high toxins, but in results, they do not have the ability to resist in the high level of toxins, so they get eliminated or died.
Therefore, the level of toxin in fishes that lives in the area of the same pollution may differ due to the ability to consume toxins.

False
Answer:
True
Explanation:
This is because as mantle convection slowly creep molecules that are warmer into the motion or movement in mantle cells, the cooler part of the rock move out of the mantle in the earth, convection currents continue to flow that carries heat into the mantle core. The mantle remain solid, the convection current that carry heat to the core, cause deformation of geologic structures on the mantle.

Chromosomes of cancer cells are often damaged mutated or missing parts, thus making them different from normal cells.How could these lead to different types of cancers?This can lead to different types of cancer, because when the genes replicate and cross over, the mutated genes are transferring. This can lead to ill functioning cells that lead to cancer.Essays Some types of cancer result from changes to individual genes, whereas others result from chromosome-level changes to the genome. Which of these types of cancer would you be able to detect by karyotype and why? Both would able to be detected by a karyotype.Because genes are on the chromosomes, when the individual genes are changed, it alters the appearance of the chromosome, which can be detected by a karyotype.When looking at the genome, one can see all the chromosomes making up the organism. If there was an alteration with the chromosomes, the karyotype would detect it.

DESCRIBE how the defect in the Single-Mutant (Sev−) R7 precursor cell causes the cell to become a cone cell instead of a photoreceptor cell
Answer and Explanation:
Cells directed their growth by getting the signals from distant or local bases and respond by directing signals. Each signal changes the cell state and decides how cells reply to consequent signals. RTK (receptor tyrosine kinase) signaling is needed for the arrangement of the R1-R7 photoreceptors. It activates the phyllopod transcription through the Ras/MAPK pathway. The Phyllopod transcription codes an adapter protein that guides the ubiquitin ligase Sina to target the transcription factor named Ttk (tram track) for deprivation. Tram track (Ttk) is the main inhibitor of the development of photoreceptors. The cells that do not damage Ttk become the ommatidium components, while those cells that damage it continues to develop photoreceptors. Receptor tyrosine kinase signaling is also involved in the development of ommatidium. Receptor tyrosine kinase signaling controls the propagation and existence of cells before they are employed in the cluster. RTK also regulates the differentiation of cone cells. Whether a cell becomes a photoreceptor or not is also decided by RTK signaling events.

Factors that affect drug absorption include: (Choose the best answer.) Group of answer choices Protein-binding properties of the drug molecule Ability to chew and swallow Liver enzyme activity Lipid solubility of the drug
Answer:
The Factor that most affects drug absorption s the Lipid solubility of the drug
Explanation:
For a drug to accomplish its pharmacological function, it needs to suffer absorption mechanisms.
Most drugs, those that do not act locally, need to be correctly concentrated in their action sites or target sites. The first step is absorption.
This involves the obligated pass through the semipermeable plasmatic membrane to finally get in the blood. In blood, the drug moves, distributes, metabolizes, and the unaltered molecules are excreted.
There are different mechanisms in which drugs can cross the membrane that depends on the drug type. Depending on the effects of these mechanisms, there will be a more or less concentrated drug at the target sites.

Although all of the cells of a human develop from one fertilized egg, the human is born with many
different types of cells. Which statement best explains this observation?
a. Developing cells may express different parts of their identical genetic instructions.
b. Mutations occur during development as a result of envirnmental conditions.
C. All cells have different genetic material.
d. Some cells develop before other cells.
Answer:
a. Developing cells may express different parts of their identical genetic instructions.
Explanation:
Humans are multicellular organisms i.e. we possess many cells in our body. These cells increase as a result of division. Although all of the cells of humans develop from one fertilized egg (zygote), the human is born with many different types of cells because of a process called CELL DIFFERENTIATION.
Cell differentiation is a process in multicellular organisms where a cell becomes more specialized in function as it divides. The set of genes contained in each cell are not expressed simultaneously i.e. some genes are expressed while others are repressed. This is how cells with the same gene possess different functions. Therefore, according to this question, developing cells may express different parts of their identical genetic instructions to be of different types.

What do you call the process of water seeping into the ground?
Answer:
Process of seeping (flow or leak slowly through a porous material or small holes) of water into the ground is called infiltration. Infiltration is the process by which water on the ground surface enters the soil.
Water not used by plants moves deeper into the ground. The top of the water in the soil, sand, or rocks is called the water table and the water that fills the empty spaces and cracks is called groundwater. Water seeping down from the land surface adds to the groundwater and is called recharge water.
Hence The process of water seepage into the ground is called Infiltration.
Consider a diploid organism. What is the genotypic ratio expected to be observed in the offspring produced by two heterozygous parents
Answer:
See the answer below
Explanation:
A diploid organism is one that has 2 copies of each of its genes. When the two genes are the same, they are said to be homzygous, and when they are different, they are said to be heterozygous.
In this case, let us assume that the trait in question is represented by A for the dominant version and a for the recessive version. Since the parents are heterozygous, it means their genotypes would be Aa.
Aa x Aa
AA Aa Aa aa
Hence, the genotype ratio would be 1AA:2Aa:1aa. In other words, the genotypic ratio of homzygous to heterozygous offspring would be 1:1 because AA and aa are both homzygous while Aa is heterozygous.
The geno-typic ratio expected to be observed is 1:1
The following information should be considerd:
A diploid organism is that where it has 2 copies of each of its genes.When the two genes are similar, they are said to be homo-zygous else hetero-zygous.Since the parents are heterozygous, it means their genotypes would be Aa.
Aa x Aa
AA Aa Aa aa
So here the ratio should be 1:1
