3. What adaptation of land plants helps it to control gas exchange with the atmosphere?

1 answer:

6 0

3) C. Stomata, as I explained in my previous answer.

4) B. Nonvascular, low-hanging plants living in moist environs don't have to fight gravity nearly as much as tall ones do. So they needn't highly developed vessels to transport to their tips

5) B. Gravity, see above. The higher trees/plants grew, the further their apical structures were from ground water sources, so the lignin-supported, strong vascular tissue (phloem) allows the transport of water against gravity, using a capillary method (benefiting from the adhesive effect of water molecules).

Why virus, virions, prions have no place in five kingdom classification

Ainat [17]

Hey, there!!

There is no place for virus, virions, prions in kungdom classification. The reason is they show both living and non living characters, which don't define them whether they are living beings or non living things.

As in 5 kingdoms, the only living organisms are classified.

Kingdom Monera mostly deals with the organism which contains prokaryotic cells.
Kingdom Protista deals with the organism which have eukaryotic cells.
Kingdom Fungi deals with various fungal organism.
Kingdom Plantae deals with various type of plants.
Kingdom Animalia deals with various type of animals.

So, you can see that there is non of the kingdoms which deals with the organism which have similar characteristics like viruses, virions and prions.
