A hypothesis is considered scientific if it has something that can be supported or refuted through carefully crafted experimentation or observation
Answer:
Birds have a different mating season this evidence will go against the argument and suggest that the birds are actually different species. Generally, two factors seasonal and behavioral identifies the differences among the species. Species generally interbred among the same population of species according to the season and hence they loose mating opportunities. Although being sexually compatible they do not interbreed. Behaviorally, a biological clock in species naturally sets breeding cycle according to the resources availability, suitable nesting sites and mating opportunities. Different species have different seasonal requirements to accomplish this.
The carbon fixation occurs in the stroma, which is the colourless fluid that bathes the grana inside the chloroplast.

Answer: A( adenine) G (Guanine) C (Cytosine) T (Thymine) U (Uracil)
Why? Nucleic acids are polynucleotides—that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. ... Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U).
Answer:
c. AATGGAGTT
d. AATAGAGTC
Explanation:
SNP is a single nucleotide polymorphism. It means that a particular sequence varies among the members of a population with respect to the single nucleotide. The given sequence of the human genome is "AATGGAGTC". The sequence "AATGGAGTT" of option C differs from it with respect to the single nucleotide at the last position (C is replaced with T).
Similarly, the sequence of option D "AATAGAGTC" differs with respect to the nucleotide at position 4 (G in the original sequence is replaced with A). Therefore, these two sequences represent SNP with respect to the given sequence of the human genome.
