Answer:
The white one as it would blend in better ie be camouflaged and less at risk to be eating by a predator
Explanation:
The moth that would survive in the bunch of trees pictured is white pepper moth.
What is camouflage?Camouflage, also known as cryptic coloration, is a defence or tactic used by organisms to conceal their appearance, usually in order to blend in with their surroundings.
Camouflage is used by organisms to conceal their location, identity, and movement. This enables prey to avoid predators while also allowing predators to sneak up on prey.
The peppered moth (Biston betularia) is a night-flying moth found in temperate regions.
The light-colored moths were difficult to see as the soot lightened the trees.
They were less likely to be eaten by birds, whereas dark-colored moths could blend in better on darker trees. As a result, dark-colored moths had a lower survival rate.
Thus, there is better survival rate of white moths in the given scenario.

O Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same container. What does this tell you about the make-up of the pigments for each specimen?
Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.
1. What is the gradual change in populations over time?
2. What is the idea that species originate in small gradual steps over time?
1. Gradualism
2. evolution
Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.
2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).
Explanation:
witch part of the plant gives leaves their green color

Explanation:
TRUE OR FALSE: DNA sequences are exactly the same for organisms that are related to each other. (If false please explain).
Answer: False
Explanation:
DNA sequences can be similar for organisms that are related to each other but through various steps of meiosis like crossing over and law of independent assortment we can get genetic variations that lead to slight differences. We can also get differences in DNA sequences due to mutations.
A new island has recently formed off the coast of Hawaii. What must
occur for it to become a stable ecosystem (climax community)?
Primary Succession
Secondary Succession
Tertiary Succession
Aquatic Succession
Answer:
Primary Succession
Explanation:
This is the first step for an environment in terms of its life cycle. The first plants (pioneer plants to be specific) to inhabit this new island will help make a layer of soil that the Secondary Succession stage will not have to go through. The creating of soil takes THOUSANDS OF YEARS so this would be associated with Primary Succession.
