Answer:
B. a decrease in the number of pathogens in the body
Explanation:
White blood cell includes immune cell like monocytes, macrophages, neutrophils, basophils, eosinophils, etc. These cells are responsible for fighting with the pathogens or foreign molecules and eliminate them from the body.
So when any pathogens get enter in the body these cell kills those pathogen and protect us from them. Therefore the decrease in the number of pathogens in the body is a direct indication that the white blood cells in the body are working. So the right answer is B.

Answer:
You can record an observation; an inference is an idea.
Explanation:
Observation is the act of observing, it means having your attention directed to something specific, with the intention of later judging, analyzing or investigating a certain thing or someone. An observation can be recorded, filmed, photographed and recorded in any way that helps you to reason about what you observed. From the observation you can make an inference.
Inference is the action and the effect of inferring (deducing something, drawing a conclusion from something else, leading to a result). Inference arises from an observation and mental evaluation between different expressions that, when related as abstractions, allow us to trace a logical implication. In crazy words, inference is an idea.
B.Nucleus is the cell part that contains an organism's genome.
Answer:
1:1:1:1 walnut comb
Explanation:
If a cross is made between a female who is RRpp (rose comb) and a male who is rrPP (pea comb) then:
P: RRpp x rrPP
F1: RrPp RrPp RrPp RrPp
This means that all of the offspring in F1 generation will have heterozygous genotype (at both loci). Since it contains both dominant alleles, the phenotype is walnut comb.
