Answer:
C. Introduce new predators to an environment
Explanation:
These new predators would have no predators themselves meaning that they can go on a rampage without being attacked by other creatures. that would definitely increase the rate of endangered species
A and B are true of whole populations but not individuals and they are not something that young animals can "do" - we reject these options.
C. Yes- this means that they leave the territory of their parents and search for new territories: this is the correct answer.
Answer:
D
Explanation:
This is a typical monohybrid cross involving a single gene coding for seed shape in a plant. The allele for round seeds (R) is dominant over the allele for oval seeds (r) i.e. the round shape will mask the expression of the oval shape in a heterozygous state (Rr).
Hence, in a cross between two heterozygous parents (Rr), alleles on chromosomes will randomly separate into gametes according to Mendel's law of segregation to produce gametes with R and r allele each. When these alleles from male and female parent combine, four offsprings with RR, Rr, Rr and rr genotypes will be produced.
RR, Rr and Rr genotypes will be phenotypically round-seeded while rr will be phenotypically oval-seeded. Therefore, 3/4 × 100 = 75% of the offsprings will be round-seeded.
