Water because it is essential to human life.
Answer:
NNllddMM or NnllddMm
Explanation:
Given -
a) Allele representing long neck is N and allele representing small neck is n
b) Allele representing Long legs is L and allele representing short legs is l
c) Allele representing Dark spots is D and allele representing light spots is d
d) Allele representing ability to digest plant material with high cellulose levels is M and disability to digest plant material with high cellulose levels is m
Genotype for Lock neck would be NN or Nn
Genotype for short-legged would be ll
Genotype for light-spotted would be dd
Genotype for cellulose-digesting giraffe would be MM or Mm
Hence, genotype of a giraffe with long-necked, short-legged, light-spotted, cellulose-digesting giraffe would be NNllddMM
or NnllddMm
Explanation:
A leaf of the embryo of a seed plant, which, upon germination, either remains in the seed or emerges, enlarges, and becomes green; a seed leaf.
Its types are monocots and dicots
Answer:
Sporophytes were branched before the evolution of vascular tissues
In early land plants the gametophytes were branched and complex like the sporophytes
Explanation:
The fossil record shows that early land plants appeared in the Ordovician Period, approximately 470 million years ago (Mya). These plants were non-vascular plants (e.g., mosses and liverworts) which can be recognized as fossilized spores. Thus, the first land plants could not transport nutrients like sugar, water, or minerals around the plant. Nowadays, it is believed that early land plants had gametophyte dominant life cycles (haploid life phase), while vascular tissues evolved as an adaptation to life on land, in the sporophyte (diploid life phase).
