Answer:
Explanation:
Electric field is a vector quantity whose direction is defined as the direction that a positive test charge would be pushed when placed in the field. Thus, the electric field direction about a positive source charge is always directed away from the positive source.
Answer:
B. R is dominant to r, and Rr individuals are red.
Explanation:
In genetics the dominant allele is represented by the uppercase letter and the recessive allele is represented by the lower case letter. A dominant allele always shows its dominance over the recessive allele. So in heterozygous condition dominant allele will reflects itself in the phenotype.
Here allele of red color allele is in capital letter and alleles of green color are shown in lower case which means R allele is the dominant allele and r is the recessive allele. Therefore R is dominant to r and in homozygous condition(Rr) red individual will be formed. So the right answer is B.
Protists are eukaryotic organisms that cannot be classified as a plant, animal or fungus. They are mostly unicellular, but others like algae are multicellular. Protists have mitochondria responsible for respiration to produce energy to be used by cells. Additionally, they can be parasites and mostly prefer aquatic or moist environments. They may be classified as animal-like protists (heterotrophs and have ability to move), Plant-like (autotrophs that photosynthesize) and fungi-like (heterotrophs with cells that have cell wall and reproduce by spore forming). Protists reproduce by asexual means (e.g. budding) or sexually. Therefore, in this case we may conclude that they are all parasites and reproduce sexually or asexually.
I think it could be letter B maybe I may be wrong I’m a beginner
Answer:
In bees, The males (drones) genes are 100% the queen's genes (develops from the unfertilized egg), this is haplodiploid, but the females (workers and queens) have 100% of the father's gene but 50% of the mothers (queen)
Explanation:
In relatedness or diploid, both parents share and pass on a complete set of genes to the offsprings, but for haplodiploidy, all the genes of one parent are passed to the offspring excluding the other parent as in the case of drones to queen bees.
