Answer:
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell's activities, while RNA converts that code into proteins to carry out cellular functions.
Acid rain can have a pH between 1.5 and 5.0. The effect of acid rain on the environment depends on the pH of the rain and the characteristics of the environment. It appears that acid rain has a negative effect on plants. The scale below shows the pH of normal rain. Provide the information requested below that should be included in a research plan to test the effect of pH on the early growth of bean plants in the laboratory.

the soil is the most important part of any ecosystem because it supplies nutrients and water for the plants and in turn the animals that eat the plants and the animals that eat them.
what would be a good hypothesis for does caffeine increase the heart rate of an earthworm
A hypothesis is usually an if then because statement, but the answer will differ as there may be multiple hypotheses to use for a single experiment.
If an earthworm had an intake of caffeine, then their heart rate would increase because it would happen the same for humans as well.

What caused the tree bark to become darker?
In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?
In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?
During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.
Answer:
conclusion
Explanation:
hope this helps
Answer:
1. What caused the tree bark to become darker than it was, was the soot from factories in the Industrial Revolution.
2. The light-colored peppered moths have a higher rate of survival on the light bark since it's the same color as it and can't be easily spotted.
3. The dark-colored peppered moths have a higher rate of survival on the dark bark since it's the same color as it and can't be easily spotted.
4. What caused the population of light-colored peppered moths to decrease was the color of the tree bark. The tree bark was dark from the soot from factories. If the tree bark was a dark color, then light-colored peppered moths are more easily spotted, and since the tree bark is a dark color the dark-colored peppered moths can hide more easily, and not be as spotted than the light-colored peppered moths.
5. You have to answer this question. If the tree bark is a dark color, then the dark-colored moths have a better chance of surviving, but if the tree bark is a light color, then the light-colored moths have a better chance of surviving.
Model: To determine the probability of a trait combination such as black fur and red eyes consider each trait separately. Fill in the Punnett square for each trait. Then determine the probability of black fur and the probability of red eyes. Express each probability as a fraction.
Answer:
3/8
Explanation:
I think I can help with completing the question.
Above each punnet square, the genotypes of the parents were given right? something like this:
Parent 1 fur genotype: Ff Parent 1 eye genotype: Ee
Parent 2 fur genotype: Ff Parent 2 eye genotype: ee
F f E e
F FF Ff e Ee ee
f Ff ff e Ee ee
Probability of black fur if dominant is: Probability of red eyes:
3/4 2/4= 1/2
Probability of a trait combination such as black fur and red eyes is
3/4*1/2 = 3/8.

On March 3, 1940, Aunt Molly Jackson led off the evening at the Forrest Theater. The wife of a leading coal striker, she’d been organizing the miners and writing songs about the abysmal conditions of the Kentucky mines until death threats forced her to relocate to New York City.
Which statement best summarizes the connection between Jackson’s life and her music?
She was asked to perform first because her songs were better than the other musicians’.
She started the performance because she was the wife of a leading coal striker.
She relocated to New York City because her songs led to death threats against her.
She hoped her songs would inspire miners to continue to work in the mines despite the conditions.

A substance valued or required by any organism(s) for survival is defined as a ____
Answer: resource
Explanation:
A substance valued or required by any living organism(s) for survival is defined as a resource.
What is living organism ?The environment consist of both living and nonliving organisms with two interacting components such as Physical or abiotic and biological or biotic components.
The physical component are temperature, light, soil, air, and water where as the biological component are animals, plants, and microorganisms.
The biotic components are plants, animals, and micro-organisms while green leaves of the autotrophic plant have chlorophyll and this pigment help in making food using light, water, and carbon dioxide by the process of photosynthesis.
Animals on the other hand are heterotrophs need nutrients and absorb nutrients such as nitrogen, phosphorus, and calcium from the soil.
Decomposer and Scavengers feed on the dead bodies and decaying substances, animal release the nutrients trapped inside them.

how does heat from the sun warm the earth?
Answer: the sun heats the earth through radiation
Explanation:
Answer:
Heat from the sun may warm the Earth when greenhouse gases absorb infrared radiation (IR), which you cannot see but can feel as heat. Dark surfaces also play a huge role in heating up Earth's surface, as they reflect less light and absorb most of the energy from the sun, in contrast to lighter surfaces, which reflect more light than it absorbs.

What might happen to the Burmese python population over time as it reaches or
surpasses its carrying capacity in South Florida? How might other organisms in the
ecosystem be affected? What might happen to the population sizes of various types
of organisms in the Everglades?
Answer:
If the Burmese Python surpasses its carrying capacity, the other organisms might not have enough food, or there is barely a chance of survival for the pythons' prey. The population sizes of other organisms might go down, and go to..extinction :/.
Explanation:
If the Burmese Python exceeds its carrying capacity, other creatures may starve or the pythons' prey may not survive. Other creatures' populations may go extinct.
What is carrying capacity?The typical number of individuals belonging to a species that are found in a given ecosystem is one definition of carrying capacity. The population size of the species is restricted by environmental conditions such as the availability of sufficient food, shelter, water, and mates. In the event that these requirements are not fulfilled, the population will continue to decline until the resource levels recover.
Therefore, if the Burmese Python population grows above its carrying capacity, the other creatures in the area may not have access to enough food, and the prey of the pythons will have an extremely low chance of surviving. It is possible that the population sizes of other organisms will decrease, leading to their eventual extinction.
