Answer:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
Explanation:
According to the rules of human genetics, if Betsy and Rudolph have a calf it will have a black nose.
What are alleles?
- The substance that is stably passed down, unchanged, from parent to offspring through the gametes, over successive generations is called as ‘factors’ now called as genes.
- Genes, therefore, are the units of inheritance. They contain the information that is required to express a particular trait in an organism. Genes which code for a pair of contrasting traits are known as alleles, i.e., they are slightly different forms of the same gene.
- Since Betsy has a dominant trait and doesn't carry any recessive gene and Rudolf has a recessive trait, their phenotypes will be NN and nn respectively.
- Mendel proposed that in a pair of dissimilar factors, one dominates the other and hence is called the dominant factor while the other factor is recessive. In this case N (for black nose) is dominant over n (for red nose), that is recessive.
- From the punnet square it is seen that the all the fertilisations lead to individuals having 'black nose' only and none of them will have 'red nose'.
- Within the genotypic pair Nn only one character N 'black nose' is expressed. Hence the character N or ‘black nose’ is said to dominate over the other allele n or ‘red nose’ character.
- It is thus due to this dominance of one character over the other that all the calf will have 'black nose' with Nn as the genotype.

In co dominance, both alleles show. Thus, the filial, F1, generation, will most likely be white with red spots/speckles. See image below.
Then answer is b. Cnidaria
Answer:
During an investigation, the addition of radiolabeled amino acids during protein synthesis occurs when the data shows high levels of radiation in protein synthesis, packaging and transport, which is equivalent to saying that radioactivity levels would first increase in the rough endoplasmic reticulum, followed by the Golgi and then the secretory vesicles (option C).
Explanation:
Protein synthesis in the cell is a process that involves the formation of polypeptide chains with the successive incorporation of amino acids.
RNA, which contains the sequence of triplets or codons that form the genetic code, is coupled to the ribosomes. Each codon or triplet consists of three nucleotides and encodes specific amino acids.
The RNA chain contains a specific nucleotide sequence and determines the assembly of amino acids to a polypeptide chain, by the action of ribosomes present in the rough endoplasmic reticulum.
In the Golgi apparatus, the proteins formed are conjugated, with the addition of carbohydrates or lipids, and arranged in secretory vesicles for transport.
In these steps, where the labeled amino acids are present, the levels of radioactivity would increase in the rough endoplasmic reticulum, the Golgi apparatus and the secretory vesicles.
