Answer:
A: The balloon expands
Explanation:
Since the heat is absorbed by the balloon, the molecules inside will spread apart. When this happens, the balloon will also expand as the molecules expand which therefore the balloon grows.

What is one reason why life probably does not exist on Jupiter, Saturn, Uranus, and Neptune?
A.) They have no gravity
B.) They are the gas planets
C.) They are the giant planets
D.)They are the rocky planets.
Answer:
I would say your best answer choice would be B - They are the gas planets.
C and D are just stu.pid, and you should have enough common sense to rule those out
With A, we can survive without gravity (hence space stations, astronauts, ect)

Explain the role of bryophytes in soil formation
Answer:
Bryophytes prevent soil erosion. They usually grow densely and hence act as soil binders. Mosses grow in dense strands forming mat or carpet like structure.
Explanation:
You want to build a house in an area with a maximum amount of species diversity. For building the house you have to clear up to 3/4th of the forest cover. How do you think this will affect the water runoff?
Answer:
The runoff will increases.
Explanation:
The runoff will be adversely affected if the 3/4th of the forest cover is removed because forest cover lowers the intensity of runoff by absorbing most of the water. The construction of house will increase the runoff due to little vegetative cover for the absorption of water and more water will runoff on the surface that will leads to flood condition in the lower elevated region of that area. The vegetative cover of the forest helps in preventing the flood condition by absorbing the runoff water.

Which of the following best explains the evolutionary basis of human skin color? two parents who are heterozygous for each of the alleles have a greater probability of having a child with medium skin than one with very light or very dark skin in a diverse population, the distribution of the trait will be a bell curve, so most people will fall in the middle the inheritance of the alleles from each parent is completely random but in a population there may be natural selective pressure from the environment to favor different levels of expression multiple genes and multiple alleles each have an additive effect on how intensely the trait is expressed.
Answer:
From the given Options, Option C is correct.
the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression
Explanation:
The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.
The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option C.

Grasses → mice → cat → coyote A natural disaster of a fire has occurred what could happen to this food chain? The grasses will be gone and all of the consumers will be able to leave. The grasses will be gone and some of the mice will die but the number of cats and coyotes will remain the same. The grasses will be gone but the number of consumers will all stay the same. The grasses will be gone and any surviving consumers will have to look for new resources in that environment. Nothing will happen to this food chain.
Answer:
The grasses will be gone and any surviving consumers will have to look for new resources in that environment.
Explanation:
The fire will destroy the grass and harm some of the consumers. Without grass, the mice population will drop and that will cause the cat population to drop and that will lead to the coyote population to also decline. The remaining consumers will have to move to find further resources to survive.
Answer:
The answer will be D

Select the statement below that describes a critical finding of the Franklin DNA diffraction experiment. Group of answer choices That the phosphate groups are stabilized by the presence of divalent metals in solution That base stacking is the primary force holding the DNA helix together That B-form DNA helices have a pitch of approximately 34 angstroms That the DNA bases are predominantly found in their keto form That the number of adenine residues is always equal to the number of thymine residues in a double stranded DNA molecule
Answer:
That B-form DNA helices have a pitch of approximately 34 angstroms
Explanation:
Rosalind Franklin was an X-ray crystallographer whose work contributed to the discovery of the molecular structure of DNA molecule by Watson and Crick. B-form DNA is the most common form of DNA, which consists of a right-handed double helix. B-form DNA was discovered by Watson and Crick based on the X-ray diffraction image of DNA (popularly known as image 51) obtained by Franklin. The pitch refers to the distance after every 10 base pairs along the DNA helix for one complete double-helix turn. This distance in the B-DNA helix is 34 Ångströms (i.e., 3.4 nanometers).
Which of the following is NOT an example of a pre-zygotic barrier?

Drag each label to the correct location on the table. Sort the observations based on whether they are quantitative or qualitative.
Answer:
Qualitative observations are those that cannot really be counted or measured by empirical figures, but are rather described by the features they have such as their color or taste.
Quantitative observations can be measured and counted by empirical figures i.e. numbers such as age and temperature. Number operations such as addition can be performed on them as well.
Qualitative observations.

Define the following
Organism:
Population:
Community:
Ecosystem:
Biome:
Biosphere:
Answer:
Population: a group of an individual species
Community: a group of multiple species
Organism: A living thing
Ecosystem: ecosystems include more than a community of living organisms (biotic) interacting with the environment (abiotic)
Biome: a set of ecosystems sharing similar characteristics with their abiotic factors adapted to their environments.
Biosphere: the sum of all the ecosystems established on planet Earth. It is the living (and decaying) component of the earth system.
Explanation:
The definition of the given terms are as follows:
Organism: They may be defined as a living thing that has an organized structure and the ability to react to stimuli, reproduce, grow, adapt, and regulate the mechanism of homeostasis.Population: It may be defined as the group of individuals belonging to the same species living in the same area at a given time. What is Community?A community may be characterized as a group of individuals belonging to different species living in the same area at a given time.
An ecosystem may be defined as the place or an area where members of different species live together and interact with one another for the purpose of food, shelter, space, and mating partner.
A biome may be characterized as a very large ecosystem that is significantly running in nature in an unmanaged area. While the biosphere may be defined as the region of the Earth where life can be found, including the soil, water, and air.
Therefore, the definition of each term is well described above.
