A. Replacing wilderness with buildings to reduce the absorption of
carbon dioxide
B. Reusing old bottles and cans as insulating building materials
C. Using high-density housing to conserve resources
D. Reducing fossil fuel consumption and its associated pollution
SUBMIT
Answer:
The answer is C
Explanation:
Just did it
The sustainable building practice does the photograph show is to using high-density housing to conserve resources. Therefore, option (C) is correct.
The act of caring for these resources so that all living things can benefit from them now and in the future is known as conservation. Natural resources are the source of everything we require for survival, including food, water, air, and shelter.
Recycling the resource allows us to conserve it. For instance, many items can be recycled and repurposed into new ones. Recyclable materials include paper, plastic, glass, metal, and even electronic goods.

The diagram below shows a stack of rock layers. These layers have not changed position since they formed. Examine the diagram and answer the question that follows. If the age of Layer 4 is 400 million years and the age of Layer 1 is 500 million years, then the age of Layer 3 is A. older than 500 million years. B. between 400 million and 500 million years. C. 500 million years. D. younger than 400 million years.
The age of layer 3 will be between 400 million and 500 million years. Therefore, option (B) is correct.
Why rock dating is important?Finding estimates of the ages of rocks is essential for identifying the speeds of geological processes as well as the history of geological occurrences. Some rocks may be used to determine the relative sequence of events. The most well-known methods are uranium-lead dating, potassium-argon dating, and radiocarbon dating.
Radiometric dating, which considers the ratio of two distinct isotopes in a sample, establishes the age of rocks. Geologists may use tools like these to assess the age of a material since radioactive isotopes degrade over a predictable period of time. mass spectrometer for thermal ionisation

Answer:
b
Explanation:
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

a. The roots of the trees in forests reduce soil erosion.
b. Trees absorb oxygen and release carbon dioxide into the atmosphere.
c. Forests are a source of a great amount of biodiversity.
d. The trees in forests play an important role in the hydrologic cycle.
Answer:
a. The roots of the trees in forests reduce soil erosion.
c. Forests are a source of a great amount of biodiversity.
d. The trees in forests play an important role in the hydrologic cycle.
Explanation:
Took the test
The importance of the forest is that roots of the trees in forests reduce soil erosion, forests are a source of a great amount of biodiversity, and also trees in forests play an important role in the hydrologic cycle. Thus, the correct options are a, c, and d.
What is hydrologic cycle?The hydrologic cycle is the ongoing movement of water in the Earth-Atmosphere system. The water cycle is outlined as the movement of groundwater to the atmosphere and back again.
Since the vertical growing floor and resulting canopy shade create micro-niches by altering locally available light, heat, and moisture, forests have a high biodiversity.
The forest is important because the roots of trees in forests reduce soil erosion, forests provide a large amount of biodiversity, and trees in forests play an important role in the hydrologic cycle.
Thus, the correct options are a, c, and d.

Allele frequencies for a particular trait are shown over five generations for a population of sexually reproducing organisms.
According to the frequency changes over the generations, which hypotheses can be supported? Select ALL that apply.
Answer:
The answer is A,B and C
Explanation:
The correct options are A, B and D. The frequency of an allele in a population is referred to as its allele frequency.
What is allele frequency?It is calculated by dividing the number of gene copies by the number of times the allele occurs in the population.
Additionally, it is feasible to determine genotype frequencies (the percentage of people who share a particular genotype) and phenotype frequencies (the percentage of people who share a particular phenotype).
Different from genotype or phenotypic frequency is allele frequency. Calculating genotype and phenotypic frequencies is also useful for studying how populations change, although they are not the same as allele frequency.
Therefore, The correct options are A, B and D. The frequency of an allele in a population is referred to as its allele frequency.

Which statement regarding DNA packing in eukaryotes is false?
A Tight DNA packing tends to promote gene expression
B) Euchromatin can be highly expressed
с
none of the answers are false
D
A nucleosome consists of DNA wound around a core of 8 histone
molecules.
E Highly compacted chromatin is generally not expressed at all.
Answer:
The correct answer is - A. Tight DNA packing tends to promote gene expression.
Explanation:
Euchromatin which is less packed or condensed is highly expressed as it participates in the transcription whereas highly compacted chromatin - heterochromatin not expressed at all as these does undergoes the transcription process.
DNA binds around a core of 8 subunits of Histone protein in a nucleosome in which DNA is negatively charged and histone protein is positively charged protein .
DNA packing decreases its transcription and hence no expression.

What is the per capita growth rate of a population of frogs that has a per capita birth rate of 1 frog and a per capita death rate of 2 frogs?
a. 1
b. 2
c. -1
d. 0
Answer:
c. -1
Explanation:
When 1 frog is born, 2 frogs die, so it is +1 and -2.
Add them together to get the answer: 1 + -2 = -1
The per capita growth rate of a population of frogs that has a per capita birth rate of 1 frog and a per capita death rate of 2 frogs is -1. The correct option is C.
What is the growth rate?The growth rate is the specific rate of change of the variables of a specific place and specific time. Growth rate is calculated by collected data of a place, and it is compared to the former population.
The growth rate of frog is here given, the growth rate is also depended upon the death rate of the population, death rate is subtracted by the population
The per capita growth rate is 1
The per capita death rate is 2
When 1 frog is born, 2 frogs die, so it is +1 and -2.
Adding them together:
1 + -2 = -1
Thus, the correct option is c. -1.
