The first species to live on new land, such as that formed from volcanic lava, are called ________.
JulsSmile [24]

The correct answer is D. Pioneer species

Additionally, this concept differs from keystone and foundation species because these two concepts describe species that have an important role in the ecosystem rather than those that first live on new land. Therefore, the first species to live on new land are the pioneer species.

fgiga [73]

Answer: 25% of the children will have both anirida and migraine headache

Explanation: The man has a dominant gene for anirida and normal headache with a mom with no blindness. Therefore, the man gene is (Nn) for heterozygous anirida and (mm) for normal headaches and his wife has heterozygous gene for migraine (Mm) 'cause her dad has normal headache and homozygous gene for normal vision(nn) .

Therefore

Nnmm × Mmnn= NnMm Nnmm Nnmm nnmm.

The crossing would give birth to Offspring with nirida and migraine (NnMm) =1/4 ×100= 25%
