Answer:
8 chromosomes
Explanation:
Diploid state is when an organism have two set of chromosomes (2n) i.e. combination of two haploid (n) gametes containing one set of chromosome each. Sexually reproducing organisms whose somatic or body cells are diploid (2n) undergo meiosis to produce gametes or sex cells with haploid number (n).
Therefore, in the newly discovered Biologica terificia species of snail, if the haploid state (n) of their gametes is 4, then their diploid (2n) somatic cells must be 4 × 2 = 8.
The question specifies the chromosomal number at the G1 phase of Interphase. At this stage, the cell is preparing to undergo division by increasing in size and duplicating its organnelles but not yet its genetic material which is not until the next phase called S-phase. Hence, the chromosome number of somatic cells remain 8 at the G1 phase.
Answer:
NUMBER ONE: a) a metal pan b)cover/blanket
Explanation:
a) it retains heat because when its heated, it heats fast, if cooled it cools fast
b) a blanket/cover actually contains heat thats how it gets you warm it traps the heat that enters it and keeps it heated.
The bacterium is not susceptible to the penicillin family of antibiotics. it contains no plasmids and relatively little peptidoglycan. Adherence to the intestinal lining by this bacterium is due to its possession of a capsule.
Answer:
A frameshift mutation can be described as a genetic mutation in which a single nucleotide or more than one nucleotide is inserted or deleted from the sequence of the DNA. As the gene expresses itself in the form of triplets of a genetic code, insertion or deletion can cause devastating changes in the genetic code due to which wrong proteins will be synthesized.
Frameshift mutations can be more noticeable than the substitution mutation. In a substitution mutation, only one of the nucleotides is shifted with another. The entire genetic code is not affected by it.
