Geothermal power is generated from moving water
Oil, a renewable resource, is processed to make
jet fuel
Wind power can turn turbines to generate electrical power
d
Propane, a renewable resource, is used in some heating systems.
Answer:
B is true
i took the test
Oil is a renewable energy resource. It is processed to make jet fuel. Thus, the correct option is B.
What are renewable energy resources?Renewable energy is the energy which is derived from natural sources which are replenished at a higher rate than they are being consumed. Sunlight and wind are the two such sources of energy which are constantly being replenished from the planet. Renewable energy sources are present in plentiful amounts and are found all around us.
Jet fuels are the energy fuels which are typically made by the blending and refining of various crude oils such as petroleum distillation products including naphtha, gasoline, or kerosene in order to meet the specific military or commercial specifications required.
Therefore, the correct option is B.

A population of birds eats nuts and seeds. Some birds have larger beaks, and some have smaller beaks. A pair of birds usually produces four or five offspring each year. After several yeaers of little rain, the seeds became larger and larger. The birds with larger beaks were better at cracking these seeds. After several generations, the average beak size in the population increased. Bird beak size increasing after several generations is: a. decent with modification. b. variation. c. overproduction. d. adaptation
As far as I can tell, the answer would be D. Adaptation. The birds are evolving to adapt to their environment, and as such, their beaks are getting larger to crack larger seeds.

Grasslands typically do not flourish when large herbivores are removed. In fact, they are soon replaced by broad-leaved herbaceous dicots, shrubs, and trees. Based on your knowledge of the structure and growth habits of monocots and eudicots, suggest a reason why.
Answer:
Grasslands and herbivores have a mutually beneficial symbiotic relationship. If larger herbivores such as Kangaroos and Elephants are removed from them, they may become extant.
Explanation:
Herbivores are always hungry and they are always looking for ways to replenish lost energy. Between tree shoots and grass, they often go for the former because they are tender, easier to reach, and less difficult to masticate than the young tree shrubs.
When baby trees become bigger, their shade prevents adequate sunlight from reaching the grass, then gradually they become scanty or subdued for as long as the shade remains.
When large herbivores are removed or leave a grassland, trees have the ability to flourish. Then the results indicated above happens.
Cheers!

Explanation:
During spring in Colorado, ice on the mountain tops melts into water. Some of this water gets trapped in cracks in the mountain rocks. With winter, the water in the cracks refreezes into ice. When water freezes, it expands. This often will cause the cracks in the rocks to grow, and eventually, pieces of rock break off. What type of weathering is taking place?

What is chi-square?
Pearson's chi-square test is utilized to inspect the job of chance in creating deviations among noticed and anticipated values. The test relies upon extraneous speculation since it requires hypothetical anticipated that values should be determined.
Hence it clearly calculates the value of chi-square.

1. is Pepsi a mixture or pure substance?
2. is Sulfur mixture or pure substance?
3. is Copper penny pure or substance?
Answer:
Pepsi- Mixture
Sulfure- Pure substance
Copper penny- Mixture
Explanation:
Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype R1 R1 are red-flowered, those that are heterozygous (R1 R2 ) are pink, and those with the R2 R2 genotype are white. This is an example of incomplete dominance. (Note that superscripts are used rather than upper- and lowercase letters to describe the alleles).
a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1?b. What is the phenotypic ratio of the F1?c. If two of the F1 offspring were crossed, what phenotypes would appear in the F2?d. What would be the genotypic ratio in the F2 generation?
Answer:
a. 4 R¹R²
b. 4 Pink flowers
c. 1 Red, 2 pink and 1 white phenotypes
d. 1R¹R¹ : 2R¹R² : 1R²R²
Explanation:
This question involves a single gene coding for flower color in petunia plants. However, the allele for red flower color (R¹) is incompletely dominant over the allele for white flower color (R²), hence, a pink intermediate phenotype (R¹R²) is formed.
According to these questions;
A. If a white-flowered plant (R²R²) is crossed with a red-flowered plant (R¹R¹), all of the F1 generation will have a genotype of R¹R² (see attached image for punnet square).
B. The F1 generation, which possess a genotype: R¹R² will express the pink flower phenotype because neither of the two alleles are truly dominant over the other i.e incomplete dominance.
C. If two of the F1 offspring were crossed i.e. R¹R² × R¹R², each parent will produce R¹ and R² gametes. Using these gametes in a punnet square (see attached image), the following phenotypes will be produced in the F2 generation: Red, pink and white phenotypes
D. The F2 generation will possess a genotypic ratio of 1R¹R¹ : 2R¹R² : 1R²R².

what is a warm air mass that rises over a cold air mass?
Answer: warm front
Explanation: When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses. This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain.

PLS HELP, Why is gene flow important to the overall health of a species?
Answer:
Gene flow is an important mechanism for transferring genetic diversity among populations. ... Gene flow is expected to be lower in species that have low dispersal or mobility, that occur in fragmented habitats, where there are long distances between populations, and when there are small population sizes.
Explanation:
Answer:
Because it is important for transferring genetic diversity among populations. Even low levels of gene flow can have a large impact, counteracting the other evolutionary force.
