Does social distancing increase or decrease your carbon footprint?

Andrej [43]

Answer:

Decrease

Explanation:

The carbon footprint is the amount of carbon (in terms of greenhouse gases) being emitted by human activities. In a situation where social distancing is encouraged, human activity would reduce significantly. Very few people will be outside and the causative agents of pollution (anthropogenic) will be significantly reduced. Further, nature would be able to minimize the impacts of pollution when human activities are less than the threshold capacity.

Let's take an example of coronavirus spread globally this year. The social distancing of 2 meters has significantly reduced the number of people going outside. Ultimately, there are fewer automobiles on the roads and a few industries are running. The result is that the air quality index has been significantly improved. For example, in India, people from 300 km away, can see the Himalayan mountain range very clearly (see image attached). This has not happened in decades after modern industrialization.

Which of the following is a factor that, by itself, does not promote widespread changes in allele or genotype frequencies? a. Ne

defon

Answer:

A new mutation

Explanation:

A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.

However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.

In the carbon cycle, carbon can move from plants to animals. How do you think this happens?

AveGali [126]

when an animal eats plants they could be eating the carbon.

Explain Mendel's law of independent assortment and how the 9:3:3:1 phenotypic ratio among the F2 of a dihybrid cross provides ev

GrogVix [38]

Answer:

Explanation:

Mendel's law of independent assortment state that two different genes assort independently in gamete formation.

To reach this conclusion, one has to do a dihybrid cross. This means that two genes responsible for different traits need to be analyzed at the same time.

1) Starting with a parental generation of a cross between two pure lines (homozygous for both genes) with different traits, a plant with yellow and round seeds (YYRR) and another with green and wrinkled seeds (yyrr). The F1 will be phenotypically homogeneous (yellow and round), and genotypically heterozygous (YyRr).

2) If the individuals from the F1 are crossed with one another, we have to do a Punnett Square to determine the phenotypic ratio of the F2.

If the genes assort independently, the F1 individuals will produce their different gametes with the same probability. Each possible gamete will appear in a 1/4 proportion: YR, Yr, yR, yr.
The 9:3:3:1 ratio is a result of analyzing the possible phenotypes that result from the dihybrid cross.

See the attached image for an illustration of the crosses in each generation and the Punnett Square.

Assignment: 01.03 Transformation of Energy

trasher [3.6K]

The energy transformations that occur in the given devices are as follows:

Windmill - mechanical energy to electrical energy
Flashlight - electrical energy to light energy
Microwave - electrical energy to heat energy
Firecracker - chemical energy to heat, light, and sound energy
Bicycle - Chemical energy to mechanical energy
Battery - chemical energy to electrical energy

<h3>What is energy transformation?</h3>

Energy transformation refers to the processes by which one form of energy is transformed into another form.

The law of conservation of energy guides the various energy transformations that occur in the universe.

The law of conservation of energy states that energy is neither created nor destroyed but can be transformed from one form to another.

The energy transformations that occur in the given device are as follows:

Windmill - mechanical energy to electrical energy
Flashlight - electrical energy to light energy
Microwave - electrical energy to heat energy
Firecracker - chemical energy to heat, light, and sound energy
Bicycle - Chemical energy to mechanical energy
Battery - chemical energy to electrical energy

In conclusion, energy transformations occur according to the law of conservation of energy.
