Which human activity causes an immediate increase in the amount of greenhouse gases in the atmosphere?
A.
biological magnification
B.
burning fossil fuels
C.
deforestation
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.

Explanation:
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

E)
Answer: A, E
Explanation: I took the USA Test Prep and the person above me who commented said so.
An animal engaging in commensalism is as basic as a bird building a nest in a tree. Without being considerably injured or influenced by the bird, the tree offers the bird shelter and protection. Thus option A, E is correct.
What defines about Commensalism symbiotic relationship?A symbiotic relationship known as commensalism occurs when one species benefits while the other is unaffected. Usually, one species exploits the other for something outside food. For instance, mites will cling to larger flying insects to “hitch a ride.” Hermit crabs live in the dead snails' shells.
A relationship between members of two species when one species receives food or other benefits from the other without endangering or helping the latter. Commensalism.

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.

If Nation A needs a natural resource that Nation B has a lot of why might Nation A have trouble getting that resource from Nation B?
Answer:
1. Thermostat.
2. Work out of.
3. Non-renewable.
4. Renewable resources.
5. Conservativism.
6. Non-renewable resources.
7. The reason Nation A might have trouble getting that resource from Nation B could be due to lack of funds (insufficient money) to acquire it, competition for the same resource by other nations, weak bargaining power of Nation A, ability to pay more money by other nations, Nation A and Nation B might be in conflict, tariffs and quotas, etc.
Explanation:
Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.
Basically, a renewable energy source is sustainable and as such can not be exhausted.
On the other hand, a non-renewable energy refers to an energy source such as fossil fuels that takes a very long time to be created or their creation happened long ago and isn't likely to happen again e.g uranium. Fossil fuels, such as coal, oil, and natural gas, come from deep inside the Earth where they formed over millions of years ago.
Filling the missing words or texts into questions, we have;
1. Set thermostat to automatically turn off heat or air conditioning when buildings are closed to conserve energy.
2. Energy can be used more efficiently getting more work out of each unit of energy.
3. Materials, such as gravel and sand, are technically non-renewable but there is so much of the available that we are unlikely to ever run out.
4. Renewable resources can be regenerated or grow so rapidly that they reappear at the same rate or faster than they are used.
5. When we practice conservatism we make sure resources will be available in the future.
6. Non-renewable resources are resources that cannot be regenerated on a useful timescale.
7. The reason Nation A might have trouble getting that resource from Nation B could be due to lack of funds (insufficient money) to acquire it, competition for the same resource by other nations, weak bargaining power of Nation A, ability to pay more money by other nations, Nation A and Nation B might be in conflict, tariffs and quotas, etc.

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.

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.

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.
