Answer:
1 dominant allies are often represented with a capital letter
2 recessive allies however are represented with a lowercase latter
3 Heterozygous is The presence of two different alleles at a particular gene .
Explanation:
the first two questions where found in the passage
As for the third a heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles for example[ Hh, hh ]
Answer:
Functions of phosphorus in the body,
i) Formation of bones and teeth. It's a component necessary for forming strong bones and teeth in the body.
ii) It's important in helping to make protein in the body for growth. Since many proteins in the body are phosphorylated for regulating their functions.
iii) Activation of enzymes. This done through phosphorylation.
iv) Gene transcription. It provides structural importance to the gene and protein binding is by the presence of phosphorus.
Deficiency of phosphorus in the body;
i) Weak and fragile bones.
ii) Bone pain.
iii) Fragile teeth.
iv) Stiff joints.
Answer:
Answer 1: The purpose of an experiment is to test a hypothesis.
Answer 2: Scientists commonly measure intensive properties to determine a substance's identity, whereas extensive properties convey information about the amount of the substance in a sample.
Answer 3: These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.
Answer 4: Data collection tools refer to the devices/instruments used to collect data, such as a paper questionnaire or computer-assisted interviewing system. Case Studies, Checklists, Interviews, Observation sometimes, and Surveys or Questionnaires are all tools used to collect data.
Answer 5: The purpose of an experiment is to test out your hypothesis. If your hypothesis is correct, then it is a theory that could work every single time the experiment has been performed by scientists.
Answer 6: ?
Answer 7: the first step toward teaching my students how to critically think about how they structured an argument or explanation was to implement the Claim, Evidence, Reasoning (CER) framework. While the premise behind CER isn’t anything new to the way science teachers already think, it provides an entirely different approach toward how students connect their experiences and previously learned content into something that is much more reflective of being scientifically literate.
Answer 8: ?

Answer:
Generally the genetic composition of every individual are conserved in the DNA, which are expressed as Genes. <u>The part of DNA that codes fro a particular protein is called Gene. </u>These genes were inherited from individual parents by offspring during genetic processes, and are passed to next generation of initiated by the offspring.Therefore the type of characteristics or traits manifested by an individual are results of gene expressed in DNA.
<u>These traits are usually encoded as transcribed bases in mRNA, and when fully translated they are expressed as proteins . Thus each trait are translated protein. This explains the forms of transport of genetic materials from parents to offspring. </u>
<u />
The inherited traits can expressed itself fully in the offsping irrespective of other characteristics, e.g a white man who marries a black woman and all the kids are white with long hair, shows dominance of the white allele, expressed as protein, despite the presence of the black allele. such black allele is said to be recessive.
The independent assortment of genes at meiosis, the crossing over at prophase 1, and separation of the chromosomes at Anaphase 1 and II together with random fertilization by million of genetically varied haploid sperm cells ensured that no two individual are 100 % genetically identical even if they are from the same parents.
The crossing over of genetic materials ensures mixing of these material to give a genetically unique organisms from mixture of the parents DNA. In addition the independent assortment of genes ensures that homologous chromosomes do not continue their 'journey' into the same sex-cells, and therefore the genetic component of the new sex-cells (sperm or oocytes ) and the resultant offspring varies
<u>Furthermore, segregation of genes into different sperm cells and eggs cells ensures random distribution of the DNA in million of sperm cells and therefore varied traits because this DNA distribution can not be the same in each sperm or egg cells, ensuring great variation in the eventual offspring.</u>
