Answer:
B) transcription and translation.
Explanation:
DNA is the genetic material and stores genetic information. The genetic information stored in DNA is expressed in the form of genetic traits by two processes: transcription and translation. The template strand of DNA is copied into RNA strand by the enzyme RNA polymerase. The process is called transcription and occurs in the nucleus.
The RNA formed by the process of transcription serves to carry the genetic information to the cytoplasm. The mature RNA, mRNA leaves the nucleus in eukaryotes and joins ribosomes in the cytoplasm to serve as a template for protein synthesis. The process of protein synthesis is called translation as it translates the genetic information of mRNA into the amino acid sequence of proteins. Translation and transcription occur simultaneously in prokaryotes.
Answer:
The cardiovascular or circulatory system is designed to ensure the survival of all cells.
Explanation:
Organisms get the energy they need from food just like us humans do.
Answer:
D) Each egg has a one-fourth chance of having either blue long, blue short, orange long, or orange short
Explanation:
The female individual looked at in this question involves two distinct genes coding for color and length. According to the question, the female contains in her genome, orange and blue alleles on one locus and long and short alleles on another locus (i.e. OoLl, where gene O is for color and gene L is for lenght).
The female will undergo meiosis, in which the alleles of each gene will separate into gametes independently of one another (according to Mendel's law of independent assortment) i.e. each gamete will equally likely contain one maternal and paternal allele of each gene.
Due to a unique phenomenon called CROSSING-OVER, which occurs in the prophase stage of meiosis I, four genetically different gametes can be produced. The alleles will be combined in the gametes (eggs) in a way that each egg is likely to contain 1/4 probability of having a blue long (oL), orange long (OL), orange short (Ol), and blue short (ol). This combination is only possible if the alleles of each gene assort independently.
Answer:
Both of them are useful because it gives different information on the subject topic which could be an animal or a plant
Explanation:
Molecular data are data which arise from genetic compositions such as DNA and protein sequences while morphological data arise from the physical make up of an organism.
The molecular and morphological data are however equally important as they give sufficient information about a plant or animal in different and diverse ways
