how have co2 levels changed since 1870

Answers

Answer 1

Answer:

raised atmospheric concentrations of CO2 by 47% above pre-industrial levels

Explanation:

Over the past 170 years, human activities have raised atmospheric concentrations of CO2 by 47% above pre-industrial levels found in 1850. This is more than what had happened naturally over a 20,000 year period (from the Last Glacial Maximum to 1850, from 185 ppm to 280 ppm).

what is meant my urbanization and industrialization? How they degrade the environment ​

Answers

Urbanization is defined as “the process of making an area more urban” or an increase in the amount of people living in towns or cities. Industrialization is defined as “the development of industries in a country or region on a wide scale” meaning a strong military with modern weapons, factories to create things, modern cars and boats etc. Urbanization and industrialization put a strain on the environment because of carbon gases emitted, effectively warming the earth up, destruction of trees which lowers our overall oxygen available, destruction of animal homes which will kill animals or cause unwanted interactions between humans and animals, and the pollution of natural resources such as local ponds, streams or the ocean.

Which two factors are most likely to cause a plant's guard cells to open its stomata?
A. Increased gravitational pull I
B. Increased sunlight
C. Increased rainfall
D. Increased turgor pressure​

Answers

the correct answers are B and D

the increased sunlight will determine the guard cells to start photosynthesis, this will result in an incresed glucose concentration inside the guard cells .The increased glucose concentration will cause osmotic pressure to build up, so the guard cell will absorb water from neighbouring cells, this will cause increased turgor pressure that will deform the cells in order for the stomata to open

Explain the idea of "survival of the fittest" with regards to a population of beavers in a lake in which some have large incisor teeth and others have small incisor teeth.

Answers

If the beavers need large teeth to collect wood for their dams, the population of beavers with larger teeth will live longer because they can collect wood. They will them be able to reproduce therefore passing down the gene with larger incisor teeth

The study of gradual change is called evolution.

The correct answer is mentioned below.

What is evolution?Evolution is a change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.

According to the question,

If the beavers need large teeth to collect wood for their dams, the population of beavers with larger teeth will live longer because they can collect wood. They will then be able to reproduce therefore passing down the gene with larger incisor teeth.

Because biological systems are generally held at constant temperature and pressure, it is possible to predict the direction of a chemical reaction by measuring which of the following?

a. ATP concentration
b. Enthalpy
c. Entropy
d. Free energy

Answers

I think it is B hope this helped

Because biological systems are typically maintained at constant temperature and pressure, calculating the free energy of a chemical reaction allows one to predict the reaction's direction that is in option d.

What role does free energy play in the biological system?

In a biological system, the free energy is very significant, where the free energy is the amount of energy that is needed by the cells of the body to perform the function, and the negative free energy indicates that the reaction is exothermic and this energy can be used for other processes. The process where free energy is needed, known as endothermic process, must be completed when there is positive free energy.

Hence, because biological systems are typically maintained at constant temperature and pressure, calculating the free energy of a chemical reaction allows one to predict the reaction's direction that is in option d.

- Use what you have learned about dominant and recessive alleles to explain why Ravyn
is albino when neither of her parents is abino?

Answers

Answer:

Please find the explanation as to why Ravyn is albino when neither of her parents is abino below

Explanation:

According to Gregor Mendel in his law of dominance, a DOMINANT allele is a form of a gene (allele) that masks the phenotypic expression of another in a gene while the RECESSIVE allele is the allele being masked. This means that an allele can be present in a gene but in a masked or recessive condition.

According to this question, Ravyn happened to be an albino when neither of her parents is albino because BOTH of his PARENTS are HETEROZYGOUS for the skin color trait i.e. they both contain the allele for normal skin color, which is dominant, and the allele for albinism, which is recessive. Note that a recessive trait will only express itself when in a pure breed condition, hence, both parents contributed the reccesive allele (albinism) to produce the recessive condition in Ravyn.

In a nutshell, Ravyn is an albino because his parents are heterozygous and both passed on the recessive alleles to him.

Which is not a likely economic tool to address environmental issues?
Emissions fees and taxes

Responsibility for a product from production to disposal

Defunding government regulation

Answers

Explanation:

Policy-makers have two broad types of instruments available for changing consumption and production habits in society. They can use traditional regulatory approaches (sometimes referred to as command-and-control approaches) that set specific standards across polluters, or they can use economic incentive or market-based policies that rely on market forces to correct for producer and consumer behavior. Incentives are extensively discussed in several EPA reports

Two basic types of traditional regulatory approaches exist. The first, a technology or design standard, mandates specific control technologies or production processes that polluters must use to meet an emissions standard. The second, a performance-based standard, also requires that polluters meet an emissions standard, but allows the polluters to choose any available method to meet that standard. Performance-based standards that are technology-based, for example, do not specify a particular technology, but rather consider what available and affordable technologies can achieve when establishing a limit on emissions. At times, EPA may completely ban or phase out the use or production of a particular product or pollutant, as it has done with chlorofluorocarbons (CFCs) and certain pesticides. Regulations can be uniform or can vary according to size of the polluting entity, production processes, or similar factors. Regulations are often tailored in this manner so that similar regulated entities are treated equally. MARK AS BRAINLIEST IF IT HELPS
