The statement that describes one way that renewable resources differ from nonrenewable resources is that renewable resources make cleaner energy.
What is renewable and nonrenewable energy?Renewable energy refers to the energy that is collected from renewable resources, such as wind power, hydropower or solar energy.
Nonrenewable energy is the energy generated from resources that will not return, or renew, or will only return after a long period of time.
Renewable sources of energy are encouraged to be used because they release less pollution into the environment unlike their non-renewable counterpart.
Therefore, the statement that describes one way that renewable resources differ from nonrenewable resources is that renewable resources make cleaner energy.

Based on the image what would an observer see at Location A? ------------------------
(A).partial lunar eclipse
(B).partial solar eclipse
(C)total solar eclipse .
(D)total lunar eclipse
At the location A, the moon is between sun and earth. Hence, the shadow of moon partially hide sun from that region. Therefore, we can observe partial solar eclipse at location A.
What is solar eclipse ?Solar eclipse is a spatial phenomenon where, the sun is eclipsed by moon when moon comes between sun and earth. The sunlight to the earth is hindered by the moon and a shadow comes in that region of earth.
The moon only casts the outermost portion of its shadow, known as the penumbra, on earth during a partial solar eclipse because the Sun, moon, and earth are not precisely lined up in a straight line. This appears to be the sun being bit into by the moon from our vantage point.
On occasion, the moon just partially obscures the sun's disc. Sometimes a partial eclipse can be mistaken for a total one. eclipse magnitude is a measurement of the eclipsed area's size. Hence, option B is correct.

Sequence the steps, 1–4, in the order required to create a permanent slide of human cheek cells. [1 mark] Specimen dehydrated Specimen embedded in wax Specimen cut into thin 'sections' Staining
Answer:
The correct order is dehydration, embed in wax, cut into sections, staining
Explanation:
There are certain proceedings needed to obtain stained sections of vegetable or animal tissues for their microscope observations.
These steps are:
Obtention of the material: The tissue is cut to an adequate size.Fixation: When tissues are extracted from the organism, they suffer autolysis and putrefaction, so they need to be fixated in order to keep their cells in the best state possible. Fixation involves preserving the original morphological and molecular characteristics of the tissue. Fixation avoids autolysis, putrefaction, distortion, and retraction of cells and the tissue that could affect its volume or morphology. Dehydration. Once fixated, the fixator must be eliminated and the tissue is dehydrated by using a gradual series of solutions with alcohol in ascendant concentrations. Dehydration must be gradual to avoid tissue deformation. Inclusion. To obtain thin cuts that can be observed under the optic microscope, the tissues must be included in a consistent, firm substance, that might be either hydrophilic or hydrophobic. A hydrophobic medium is paraffin wax, that provides hardness and plasticity. Cut. The tissue included in wax must be cut in slides or sections thin enough to allow the diffusion and penetration of light. A microtome is used to perform these cuts. When using paraffine for tissue inclusion, the cuts are about 5 to 20 micrometers of thickness. Stain. Once the cuts are performed, paraffin wax must be eliminated. This can be done by using an organic solvent. Then the tissue must be stained. Hematoxylin and Eosin are the most common dyes. Animal tissues in general do not have any natural color, so they need to be stained to be observed.Look at the picture and observe below. Observations: The bee's wings are moving very fast. The bee's wings are much smaller than its body. Which question is based on these observations? A. How many bees are found in a hive? B. How are bees able to fly? C. What do bees like to eat? D. Are bees found all over the world?
Answer: The answer is B
How are bees able to fly is based on these observations. So, the correct option is B.
How are bees able to fly?The airflow over a bee's wing is improved by the air swirls at the leading edge of the insect's wing, which allow it to tilt its wing sharply upward. Bees, fruit flies, and even hummingbirds can fly because of this increased wing angle.
For many years, researchers were baffled as to how bees were able to fly. But eventually, they were able to solve the puzzle using high-quality footage that could demonstrate the bee wing strokes in slow motion. It was essential to comprehend bee wings in order to understand how honeybees could fly.
Therefore, the correct option is B.

Explain how temperature and precipitation are affected by latitude and the sun's rays.
Temperature and precipitation are affected due to latitude and the sun's rays. This is because the sun's rays are directly fallen on the equator at the right angle which makes this area hotter as compared to polar regions.
What is Latitude?Latitude may be defined as the measurement of the distance from the equator to the polar regions.
It is understood by the fact that when latitude increases to polar regions, a reduction in average temperature is seen. This is because, at higher latitudes, the sun's rays are less direct as compared to the equator.
At the poles, the sun's rays are least direct, and hence the temperature is very low.
Therefore, it is well described above.

someone please calculate the ratio of offspring please help pleaseeeeeeeeeeeeeeee
Answer:
2. 1 Pink : 1 white
3. 1 Red : 1 Pink
4. 1 Red : 2 Pink : 1 White
Explanation:
This question involves a single gene coding for flower colour in snapdragon plants. The alleles of the gene exhibits incomplete dominance i.e. the red allele (R) ia not completely dominant over the white allele (W), hence an intermediate pink phenotype (RW) is formed. Based on this, a red snapdragon will have genotype, CRCR while a white one will have genotype, CWCW. The intermediate pink phenotype will have a genotype, CRCW.
The image attached to this question shows four crosses between different traits.
In the second cross between a pink (CRCW) and white offspring (CWCW), 2pink and 2white offsprings will be possibly produced in the ratio 1:1.
In the third cross between a red (CRCR) and pink (CRCW) snapdragon, 2 red and 2 Pink offsprings will possibly be produced in a ratio 1:1.
In the fourth cross between a pink (CRCW) and pink (CRCW) snapdragon, red, pink and white offsprings will be produced in the ratio 1:2:1.
See attached image for the complete punnet square. Note that, there was a mistake in the Genotype of the last cross i.e. pink has genotype CRCW not CWCW.

A silver mine recently opened along the foothills of a mountain. The mine's primary method for extracting silver from the surrounding rock is heap leaching. Which of the following hazards does this process most likely pose to the environment?
I. Atmosphere contaminated with heavy metals
II. Soil contaminated with cyanide
III. Surface water contaminated with sediment
Answers:
I only
II only
III only
I and II only
Soil contaminated with cyanides is the hazard which is the most likely pose to the environment. Thus, the correct option is B.
What is Cyanide contamination?Silver mining is the extraction of silver metal from minerals, starting with mining. Because of this silver, which is often found in the intimate combination with other metals, its extraction requires more elaborate and complex technologies.
Cyanide in the landfills can contaminate the underground water. Hydrogen cyanide, sodium cyanide, and potassium cyanide are the major forms of cyanide which are most likely to be found in the environment as a result of industrial activities. Hydrogen cyanide is a colorless gas with a faint, bitter, almond-like odor. Concentrated acids and cyanides are used to dissolve metals from the rock which are picked up in rainwater.

Explanation:
.
The only thing that would not reduce the carrying capacity of an ecosystem for a particular prey species is fewer predators, which are present in Option D, as the carrying capacity refers to the maximum number of individuals present in the ecosystem.
What is carrying capacity?Various factors can affect the carrying capacity of an ecosystem for a particular prey species, such as drought and habitat destruction, which can decrease the availability of resources such as food, leading to a reduction in the carrying capacity of the ecosystem, which can result in a decrease in plant growth and food availability for herbivores, which in turn reduces the carrying capacity for predators.
