Biology

Answer:

Hope this helps!

Explanation:

Scientists say early plants may have contributed. Plants enhance a process called silicate weathering, which sucks carbon out of the atmosphere and ultimately tucks it away at the bottom of the oceans. Here's how it works: Caron dioxide in the atmosphere forms carbonic acid.

Bacteria are organisms that reproduce asexually. Asexual reproduction can
madreJ [45]

Answer:

Since all forms of bacteria are prokaryotic and in turn unicellular their offspring don’t have to undergo a long period of gestation and growth prior to relative maturity. Whereas any organism (for the most part) in the animila kingdom do and any animal also require a mate. So one major benefit of bacteria being capable of asexual reproduction is they don’t require a mate to reproduce hence the name ASEXUAL. Also, another benefit I vaguely/briefly mentioned is the ability to reproduce at a faster rate than many if not all eukaryotic organisms. For example E.coli a type of bacteria can reproduce in as little as 20 minutes if I recall correctly.

The graph below shows the radioactive decay of a material whose half life is 25 years.
yawa3891 [41]
The half life is the time taken for the amount of a substance to become half of its original value. If we take the initial value to be 30 on the y-axis, the half of 30 is 15. We check the time at which the substance has reduced to 15 atoms and this is about 40 seconds. <span>40 seconds therefore, is your answer.</span>

1. What is meant by the term semiconservative replication? How does a leading strand differ from a lagging strand? List the ways
Reil [10]

Answer:

Explanation:

Semiconservative replication is one of the type of replication methods proposed to take place in the cell and has also been confirmed to be the type that actually takes place in the cell. Semiconservative replication involves the production of two copies (of which one is the parental strand which acts as template and the other is the newly synthesized strand) of the original DNA molecule. A leading strand is the newly synthesized strange running in the 5' to 3' direction, the template strand runs from the 3' to 5' direction while the lagging strand is the newly fragmentally synthesized strand oriented in such a way that its production runs in the 5' to 3' direction for each okazaki fragment. Its template strand runs in the 5' to 3' direction.

The cell copes with errors in replication either by performing the 3' to 5' exonuclease proofreading during replication or by utilizing the cell's DNA repair system.
