Secondary succession occurs when a natural devastating calamity or event takes place such as hurricane and forest fire. It is often faster compared to primary succession because there are available resources already including soil, roots, seeds and other vegetative organs from plants can be found underground.
Answer:
Protosomes
Explanation:
Protosome is a multicellular organism whose mouth grows before the anus from a primary embryonic opening which includesphyla mollusk, arthropod or annelid. Protosomes are developed by spiral cleavage during embryo development.
Protosome animals have bilateral symmetry and three germ layers. Some of the examples of protostomes are snails and slugs (mollusk), earthworms (annelids), and spiders, lobsters, barnacles (arthropods).
Hence, the correct answer is Protosomes .
Answer:
We could feed them with another type of food free of silver salts.
Explanation:
When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.
If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.
Answer:
The correct answer is C. helps process explicit memories for storage.
Explanation:
The hippocampus is an structure of the brain and is located inside the temporal lobe. The main function of the hippocampus is to mediate the generation and recovery of memories in conjunction with many areas spread across the cortex and with other areas of the limbic system. It helps to process and recover the episodic memory (those related to events) and spatial memory (mode in which we perceive space or dimensions). This organ is also where short-term memories become long-term memories, that is, it acts as a mediator of memories, acting as an activation node that allows different memories distributed across different parts of the brain to be activated.
Chromosome is to cactus as gene is to needle.
