Answer:
The question is incomplete, the correct question is;
Which statement describes asexual reproduction, but not sexual reproduction? A) New organisms are formed only after fertiliztion. B) A single cell will not develop into a full organism. C) Daughter cells contain half the genetic material of the parent cell. D) Daughter cells contain the same genetic information as parent cells.
Answer is option D. Daughter cells contain the same genetic information as parent cells.
Explanation:
The process in which organisms creates their offspring is called reproduction and the two types of reproduction are asexual reproduction and sexual reproduction.
In asexual reproduction, the offspring are produced from a single parent. They are genetically identical to each other and to the parent. Binary fission, fragmentation, and budding are the different methods of asexual reproduction. Examples of organisms which reproduce through asexual reproduction include bacteria, yeast, amoeba, hydra etc.
In sexual reproduction, the offspring are created by two parents and they are genetically unique. The gametes are reproductive cells present in the parents, produced by meiosis. They are haploid cells containing only half the number of chromosomes. The process in which the gametes from two parents combine to form a zygote (fertilized diploid cell) is called fertilization, where the zygote has twice the number of chromosomes. The zygote develops into a fully formed organism, which has a unique combination of characteristics inherited from both parents.
Answer:
Phenotypic ratio - 3 Freckes : 1 No freckles
Explanation:
This question represents a monohybrid cross i.e. involving a single gene coding for possession or not of freckles. The allele for possession of freckles (F) is dominant over the allele for no freckles (f).
In a cross between two HETEROZYGOUS parents i.e. Ff × Ff, each parent will produce gametes with alleles F and f respectively. Using a punnet square (see attached image), four possible offsprings will be produced with genotypes: FF, Ff, Ff and ff.
Based on this genotypes, the phenotypic ratio of the offsprings will be 3:1 where 3 offsprings will possess freckles and 1 will have no freckles.
D. White dwarfs are the stars in the lower left region of the H-R diagram
Answer:
C. Elongation.
Explanation:
The RNA strand "elongates" due to the addition of new nucleotides
