Answer:

Not using fossil fuels and using renewable fuels instead.

Explanation:

Like using solar and wind power as renewable energy sources will reduce the release of acid rain as it doesn't produce as mush pollution.

Answer:

Explanation:

These gases are exerted into the sky as pollutants through human activities. Then, when the clouds form due to condensation, and become to heavy to hold, they start to release water in the form of rain. However, one slight change would be that they bring down the Sulphur dioxide and nitrogen dioxide with them.

This acid rain is mostly seen after a long summer, and when the first few rains are seen. This rain highly affects the happenings at the Earth. For example, they make the soil in fertile and leave farmers and gardeners under lots of work for when they re - plant later that year.

So, as you can see humans really have to try and stop acid rain or at least reduce it. So, they try to reduce human activities that release the acidic gases into the air in the first place. This is the only way they are able to reduce it. These human activities include burning of fossil fuels, etc.

Since reducing this means reducing luxuries, humans are able to find alternative methods to do this. Like instead of burning fuels, they can get it form solar power that is renewable

3. use the simulation to observe the first-generation offspring from the cross between flowers c and a. what is the most likely

JulsSmile [24]

To observe the first generation offspring of the cross between the flowers c and a. the most likely genotype of flower c is its color.

<h3>What is genetic probability?</h3>

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck. It can be defined by the following formula: Where P is the probability that an event will occur, A is the number of desired events, and S is the total number of possible events.

With this information, we can observe the first generation offspring of the cross between the flowers c and a. the most likely genotype of flower c is its color.

Define monohybrid cross with explanation

UkoKoshka [18]

Answer: A monohybrid cross is a breeding experiment between P generation (parental generation) organisms that differ in a single given trait. The P generation organisms are homozygous for the given trait. However, each parent possesses different alleles for that particular trait. A Punnett square may be used to predict the possible genetic outcomes of a monohybrid cross based on probability. This type of genetic analysis can also be performed in a dihybrid cross, a genetic cross between parental generations that differ in two traits.

Traits are characteristics that are determined by discrete segments of DNA called genes. Individuals typically inherit two alleles for each gene. An allele is an alternate version of a gene that is inherited (one from each parent) during sexual reproduction. Male and female gametes, produced by meiosis, have a single allele for each trait. These alleles are randomly united at fertilization.

Explanation: The single trait being observed is pod color. The organisms in this monohybrid cross are true-breeding for pod color. True-breeding organisms have homozygous alleles for specific traits. In this cross, the allele for green pod color (G) is completely dominant over the recessive allele for yellow pod color (g). The genotype for the green pod plant is (GG), and the genotype for the yellow pod plant is (gg). Cross-pollination between the true-breeding homozygous dominant green pod plant and the true-breeding homozygous recessive yellow pod plant results in offspring with phenotypes of green pod color. All genotypes are (Gg). The offspring or F1 generation are all green because the dominant green pod color obscures the recessive yellow pod color in the heterozygous genotype.

Monohybrid Cross: F2 generation

Should the F1 generation be allowed to self-pollinate, the potential allele combinations will be different in the next generation (F2 generation). The F2 generation would have genotypes of (GG, Gg, and gg) and a genotypic ratio of 1:2:1. One-fourth of the F2 generation would be homozygous dominant (GG), one-half would be heterozygous (Gg), and one-fourth would be homozygous recessive (gg). The phenotypic ratio would be 3:1, with three-fourths having green pod color (GG and Gg) and one-fourth having yellow pod color (gg).

What Is a Test Cross? How can the genotype of an individual expressing a dominant trait be determined to be either heterozygous or homozygous if it is unknown? The answer is by performing a test cross. In this type of cross, an individual of unknown genotype is crossed with an individual that is homozygous recessive for a specific trait. The unknown genotype can be identified by analyzing the resulting phenotypes in the offspring. The predicted ratios observed in the offspring can be determined by using a Punnett square. If the unknown genotype is heterozygous, performing a cross with a homozygous recessive individual would result in a 1:1 ratio of the phenotypes in the offspring.

Using pod color from the earlier example, a genetic cross between a plant with recessive yellow pod color (gg) and a plant heterozygous for green pod color (Gg) produces both green and yellow offspring. Half are yellow (gg), and half are green (Gg). (Test Cross 1)

A genetic cross between a plant with recessive yellow pod color (gg) and a plant that is homozygous dominant for green pod color (GG) produces all green offspring with heterozygous genotype (Gg). (Test Cross 2)
