Answer:
Prophase 1
Explanation:
In prophase 1, homologous chromosomes pair up and exchange sections of DNA in a process called crossing over.
Answer:
The eukaryotic plant animal cells are differ having some cell organelles in it.
Explanation:
The first difference is the cell wall, which is present in all eukaryotic plants. It gives shape and rigidity to the plants. But all the animal cell the outer covering is cell membrane. They lack cell wall.
All the plant cell have chlorophyll pigment. It helps them to photosynthesis. In animal cell, chlorophyll molecule are absent. So they depend on plants for their food.
The eukaryotic plant cell more space is occupied by the vacuoles. It stores food and water for the plants. However, animal cells have no vacuole or if present, it is very small in size.
All animal cells have lysosomes, which help in digestion of various materials in the cell. Plants does not contain lysosomes.
Besides this organelles all other structure of plant and animals are similar. They both have nucleus, DNA, cytoplasm, mitochondria, etc.
Answer:
E) horizontal gene transfer
Explanation:
Horizontal gene transfer can also be referred to as lateral gene transfer. It is the transmission of deoxyribonucleic acid (DNA) between different genomes.
Horizontal gene transfer has been shown to occur between different species, such as between prokaryotic and eukaryotic organisms.
Horizontal gene transfer is made possible by the existence of genetic elements, such as plasmids, transposons, and bacteriophages (bacteria that infects viruses).
