Name three reasons why the atmosphere is important to life on earth and explain your reasoning.
The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.
The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.
Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.

For decades, scientists relied on the fossil record and comparative anatomy to assemble evolutionary lineages. Which statement describes a limitation of these methods? (1 point) They are no longer relevant because the fossil record is complete. They can show false relationships between organisms that are not reflected in the DNA. They are not reliable evidence of how the body structures of organisms evolved. They cannot be used to determine when species evolved.
Answer: They can show false relationships between organisms that are not reflected in the DNA
Explanation:
Okay so there is a thing called "convergent evolution" which basically means that different species coming from different evolutionary lines evolve the same traits. It's really easy to mistake convergent evolution for evolutionary similarities. From the fossil record, it's easy to see the bones of one animal and to see that they are similar to another but that doesn't prove that they are related because it's often due to convergent evolution.
They can offer false relationships between organisms that are not reflected in the DNA. Also, they don't prove they are related due to convergent evolution.
What is DNA?
There is a thing called "convergent evolution" which essentially suggests that additional species coming from different evolutionary strings become the same traits.
It's really easy to misunderstand convergent evolution for evolutionary parallels.
From the fossil record, it's easy to catch the bones of one animal and to see that they are equal to another but that doesn't confirm that they are connected because it's often due to concurrent evolution.

Use a Punnett Square of a Bb x Bb cross. B is the factor for brown eyes and bis factor for blue eyes. What color eyes do the parents have:
Answer:
The parents would have brown eyes.
Explanation:
Given Bb x Bb, this tells you that both parents have brown eyes and are carriers for a reccessive trait (blue eyes). Remember that the uppercase letters are considered dominant and the lower case letters are considered recessive. In order for the blue eye allele to show, you would need to have the genotype: bb.
