The first one is option 2 but I'm not sure however the second one is the last option.
Both are seed producing
both are unisexual,however angiosperms can be bisexual
angiosperms are flowering while gymnosperms are non-flowering
angiosperms seeds are enclosed in an ovary while gymnosperms are not enclosed
angiosperms are seasonal while gymnosperms are evergreen
Answer:
Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas.
Explanation:
Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas are the three other environmental conditions besides high elevation that might result in adaptation to hypoxia. These abilities will increase the resistance to lower oxygen levels in the surrounding environment. Fish is the organism which used these types of adaptation for their survival in the surrounding of low oxygen levels.
Answer:
I would say plenty of water.
Answer:
Because eukaryotic genes contain introns
Explanation:
Eukaryotic genes are much more complex than prokaryotic genes. Some of the differences between these two groups of organisms are:
- existence of exons and introns (which are spliced during the process of mRNA processing)
- post-transcriptional modifications (poly A tail and 5' cap)
- regulatory elements which control gene expression.
On the other hand, prokaryotic genes are organized in operons, structural units that contain more that one gene, under the control of one promotor.
