Answer:

When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.

What type of mutation can affect offspring?

The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype. Some mutations don't have any noticeable effect on the phenotype of an organism.

WHY IS A FOSSIL FOUND IN MULTIPLE LAYERS OF ROCK (TIME PERIODS) NOT CONSIDERED A RELIABLE INDEX FOSSIL?
Sati [7]

Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.

Why would a drug the damages capsids help treat a viral infection
goblinko [34]
Because by damaging capsids, there is no place for the bad DNA to be stored. So the drug destroys the DNA so no more of the virus can be stored in the body.

ASAP PLEASE HELP!!!!
MissTica

Answer:

B !

Explanation:

I'm basing this off of a lesson I took two years ago, but the answer is B! The interior of Earth is rumored to be filled with magma as a way to have convection currents in itself, and to move the tectonic plates/ create the tectonic plates, if I remember correctly.

If i'm wrong I can still prove why it's not the other choices.

It's not A becuase when rock gets hotter, it rises, and when it cools, it sinks.

it's not C becuase it said "interior of the planet", which it may be referencing somewhere having to do to below the crust. as well, you need to cool rocks as to make it solid, not heated up rocks. but even then, mountains are made by the plates.

it's not D becuase glaciers are affected by climate change and occurrences the biosphere, not the interior of the planet.
