Gymnosperms are no longer restricted to moist environments, as are ferns and mosses because they have evolved to produce non-flagellated pollens that do not require water or moisture to reach the egg whereas ferns and mosses have flagellated sperm that needs moisture to swim towards the egg.

Another major evolutionary adaption in gymnosperms is the production of seeds instead of spores since seeds contain their own nutrition in the form of endosperm, seeds can travel large distances through wind or animals and can germinate when they find suitable conditions. Seeds can remain dormant for several years whereas spores have a shorter lifespan.

I would try to eat more healthily because eating certain foods are a huge magnet to toxic waste and gas. This creates more pollutions and destroys the o-zone. Another thing it to take my bike instead of car or use a hybrid or an electric car if it is to far ( my destination) for a bike. Cooking food in my house with an oven is MUCH better for the clean air as well for the coal and charcoal used for grill, and wood for fires, causes a massive pinpointed area of smoke and destroy the air causing bug leaks of hydrogen in the air molecules.

It has been observed that organisms on islands are different from, but closely related to, similar forms found on the nearest co
kaheart [24]

Answer;

A) island forms and mainland forms descended from common ancestors.

Explanation;

-Islands tend to host very distinct but limited sets or species; on a given island a spectacular collection of one related group of species would be present and thriving, but many entire families or even higher taxa would be completely absent.

-All the species on the islands and the nearest continent are closely related to one another, however, each species had a set of adaptations that suits it for a particular environment. This means that the island forms and mainland forms descended from common ancestors.

Adenine methylase is an enzyme used during mismatch repair (MMR). It helps determine which strand needs to be repaired by discri
I am Lyosha [343]

Answer:

The correct answer would be - MMR would be hindered because both strands would be unmethylated and both would appear as new DNA strands and it would not be able to determine which strand has the error .

Explanation:

In gene expression or DNA replication, the enzyme responsible for the synthesis of DNA from nucleoside triphosphate causes errors sometimes such as mismatch base pair that result in a change in genetic makeup.

For MMR, the DNA template and the strand formed required easily to be differentiated. As the newly synthesized strand is unmethylated and the DNA template strand is methylated results in DNA remain hemimethylated for a very short period.

After MMR, DNA adenine methylase enzyme that transfers a methyl group to the adenine of the sequence 5'-GATC-3' daughter strand formed.

Mutated DAM or DNA adenine methylase will not be able to transfer methyl group which leaves both template and daughter strands unmethylated and mismatch repair would be hindered as it will not be able to identify.
