Explanation:
The correct model shown is Crossing over will result in new genetic material.
What is crossing over?
When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the development of egg and sperm cells.
This process leads to novel allele combinations in the gametes (egg or sperm) produced, ensuring genomic variety in any offspring born.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father.
Therefore, The correct model shown is Crossing over will result in new genetic material.

white eyes are recessive in flies. can two red eyed flies have white eyed offspring
Answers
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies :
Red eye (R) is dominant trait. White eyes (r) is the recessive trait.When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square :
Rr X Rr
Alleles R r
R RR Rr
r Rr rr
In the offspring, the probabilities are:
50% heterozygous individuals Rr, with red eye phenotype. 25% pure dominant individuals RR, with red eyes 25% individuals with the recessive rr genotype, white eyes.This is the possibility of two red-eyed flies having white-eyed offspring.

Particles that are both solid and liquid, as well as some gases that are suspended in the air, are what produce air pollution. These gases and particles can be produced by factories, volcanoes, wildfires, dust, pollen, and vehicle and truck emissions.
The largest causes of air pollution come from industrial sources, power plants that provide electricity, and fossil fuel powered cars. The constant combustion of fossil fuels emits chemicals, emissions, and air pollutants into the atmosphere.

A corn field is divided into four parts each part is ‘treated’ with a different fertilizer to see which produces the most corn. What is the dependent variable?
1. Different Fertilizers
2. Corn Production
Answers
Answer:
The correct answer is - 2. corn production.
Explanation:
The dependent variable of a scientific investigation is a variable that depends on the independent variable. It is a variable that is required to check or find the effect of the independent variable and also known as output value that helps to know the effect of input values or independent variable.
In this case, the input value or the independent variable is different fertilizer as it is the only variable that is manipulated by the researcher, and due to this manipulation, the production of the corn affected which is the dependent variable as it depends on the independent variable.

How is land subsidence related to a rise in human population?
Land subsidence happens when the increased demand for water is countered with sound agricultural practices.
Land subsidence happens when the increased demand for water causes the levels of the water table to rise.
Land subsidence happens when the increased demand for water causes the levels of the water table to lower.
Land subsidence happens when the increased demand for water results in rapid recharging of aquifers.
Answers
Land subsidence is related to human population growth because soil subsidence occurs when increased water demand causes groundwater levels to drop.
What causes subsidence?Subsidence is a phenomenon of lowering of the ground surface due to changes in the underground support. The phenomenon occurs in several places in the world due to the
extraction of wateroil and gas from the subsoil.With this information, we can conclude that Land subsidence is related to human population growth because soil subsidence occurs when increased water demand causes groundwater levels to drop.

Like most students, Megan really enjoyed doing labs in science class. One day her teacher allowed the class to design their own experiment. Her task was to see if she could blow up a balloon using chemicals. Megan knew that vinegar and baking soda would fizz and produce a gas. However, her teacher didn't give her any vinegar to use, only dilute hydrochloric acid. Megan thought she could use the acid in place of the vinegar.
Based on the reading above, which hypothesis would be supported by the experiment?
Answers
The BALLOON BLOW UP SCIENCE EXPERIMENT provided evidence to support this claim.
When baking soda, a basic, and vinegar, an acid, are combined, a chemical reaction occurs that produces carbon dioxide gas. Instead of having a predetermined volume or shape, gases expand quickly to fill their container. Because of the fast particle motion in all directions, gases expand quickly. The carbon dioxide gas starts to fill the balloon as it fills the bottle since it has nowhere else to go. The balloon fills with carbon dioxide gas and expands as a result. The size of the balloon will increase with the amount of gas produced. A material is said to be acidic if it has a bitter taste, reacts with metals and carbonates, and turns blue litmus paper red. A base is a compound that has a bitter taste, is slick to the touch, and causes red litmus paper to turn blue.

2. In some dogs the allele for barking is dominant to the allele for non barking. How would a breeder get a strain of pure breeding barkers? Assume he has males and females of both types.
Answers
Answer:
Explanation:
Dominant traits are traits that are visible in the phenotype of an organism.
If barking is dominant in some allele of the dog and it has both male and female then a cross between the male and female with the dominant allele for barking will give a strain of pure breeder barkers.
A recessive allele cannot breed a pure barker because it does not have the allele for barking.
Hence a cross between two individual that dominos of the allele will breed true type.
Which of the following is not a way that the environment can influence traits?
the presence of toxins in the environment
through epigenetic factors
expression of the dominant trait
through variation in temperature
Answers
Answer:
The correct answer is - expression of the dominant trait
Explanation:
The ineraction of the genes such as dominant and recessive trait are incorporated in the genes and not influence by the environmental condition. These interaction are by the de noo mutations or due to the error in gene expression.
The environmental conditions like toxins cause alteration or mutation in the gene expressions. Temeprature or epigentic conditions are also the factor the can cause influence to traits.
