Answer:
Early in the development of the embryo, specialized diploid cells, called germ cells , are produced within the gonads (such as the testes and ovaries). Germ cells are capable of mitosis to perpetuate the germ cell line and meiosis to produce haploid gametes.
Answer:
For the eggs to survive and have a chance of hatching, sea turtles must lay their eggs on sandy beaches. As they are developing, the embryos breathe air through a membrane in the eggs, and so they cannot survive if they are continuously covered with water.

Answer:
Chambers
Explanation:
Oxygen-rich blood travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The heart pumps blood to the lungs and to all the body's tissues through a sequence of highly organized contractions of the four chambers.
Answer: The correct answer is- A.The plant might have a gene that is similar to a human gene.
Probe can be described as the segment of DNA or RNA (generally 100-1000bp in length) that is designed and radioactively labelled to detect the presence of nucleotide sequences, which are complementary to it.
In this question, the probe is synthesised using sample of human DNA but it also hybridizes with the plant DNA.
This indicates that plant genome has certain DNA sequence or gene that is similar to the gene in the human DNA.
Thus, option A) is the right answer.
