Answer:
They camouflage
Explanation:
The peppered moths adapt to their surroundings. They blend in with their surroundings to avoid being eaten by their predators. Blending in with their surrounding also helps them to sneak up on and catch their prey.
I'm not too sure why they lay 100 eggs at a time but i think it's because the parents want to increase the survival of their eggs. Eggs sometimes are eaten by other animals and the parents want at least a few to survive.
Answer:
For question 20. I believe the answer is C. There would be more iguanas with webbed feet.
Explanation:
It states the iguanas have adapted to different habitats on the island. The iguanas that have webbed feet will be better at getting food in water, but slower on land. So if the land starts to disappear and turns into more water, the iguanas with webbed feet will have a higher chance of survival. Meaning the iguanas with out webbed feet will die out as a population.
Answer:
<h2> After one round: one strand of DNA will contain radioactive 3232P, while the other strand will not contain any radioactive phosphate.
</h2><h2> After two rounds: here 50% of DNA will have 3232P in both strands, while 50% will contain 3232P in one strand and nonradioactive in the other strand.
</h2>
Explanation:
1. In the initial sample which is immediately removed after addition of radioactive isotope of phosphorus ( 3232P), hence there is no incorporation of 3232P into the DNA because replication in the medium containing 3232P has not yet occurred.
2. After one round of replication in radioactive isotope of phosphorus ( 3232P) containing medium, here only one newly synthesized strand of DNA molecule will contain 3232P, while the other strand will not contain any radioactive isotope of phosphorus ( 3232P), because DNA replication occurs in semi-conservative way.
3. After two rounds of replication in medium which contains radioactive isotope of phosphorus ( 3232P), here 50% of the DNA molecules will have radioactive isotope 3232P in both strands, while the rest 50% will contain 3232P in only one strand and nonradioactive phosphorous in the other strand.
Are you talking about the benthic zone?
Answer: B:Put water, fertilizer, soil, plants and insects in an open, clear glass aquarium. Place it in an area that has some sunlight
and some shade
Explanation: Alright lets analyz and simplify. First you need water of course for anything to live right. the soil and fertilizer for the plant is good because plants are autotrophs which mean through photosynthesis they can make their own food. The insectsm are heterotrophs which will help with overpopulation of plants and the sunlight and shade will allow for a balance of temperature.
