Dihybrid cross experiments led Mendel to propose his law of independent assortment.

Which statement best describes this law?


A. The law of independent assortment states that alleles of different genes are inherited together.

B. The law of independent assortment states that when two inherited alleles are heterozygous, the dominant allele is the one that is expressed.

C. The law of independent assortment states that alleles of different genes are inherited independently of each other.

D. The law of independent assortment states that alleles are separated when gametes form, causing gametes to carry only one allele for each gene.

Answers

Answer:

c

Explanation:

The answer is c: The law of independent assortment states that alleles of different genes are inherited independently of each other.

According to Mendel's law of independent assortment, the alleles of two or more distinct genes are sorted into gametes in a manner that is independent of one another. The allele a gamete acquires for one gene does not affect the allele a gamete receives for another gene, in other words. Thus, option C is correct.

What Mendel propose his law of independent assortment?

According to Gregor Mendel's law of independent assortment, genes are inherited independently of one another. Due to the fact that two genes are found on the same chromosome, linked genes constitute an exception to the rule of independent assortment; however, this effect is usually lessened when chromosomes cross over.

According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes. In other words, an allele for one gene does not impact the allele for another gene that a gamete acquires.

Therefore, The law of independent assortment states that alleles of different genes are inherited independently of each other.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which
statement best describes an environmental consequence of this process?
• Chemicals added to the liquid can contaminate groundwater.
O Wastewater is contaminated with oil and becomes sludge in landfills.
Water vapor is released into the air, which is considered a greenhouse gas.
Heavy metals are released into surrounding soil, poisoning local vegetation

Answers

The correct answer is that chemicals added to the liquid can contaminate groundwater.

Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.  

The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

How long does it take for mammals to evolve into a distinctly new species? What changes occur over
this time?

Answers

Answer:

i hope this helps <3

Explanation:

A new study by Matt Davis at Aarhus University throws these losses into stark relief. He estimated how long it would take for mammals to evolve enough new species to replace the ones that we have eradicated. And his most realistic answer is somewhere from 3 million to 7 million years.

The time that would be taken for mammals to evolve into a distinctly new species is 3 million to 7 million. The changes that will occur will be mental and physical changes.

What is evolution?

Evolution is a process of changing human characters or other animal characteristics over time. Evolution happens with time, and it is a natural process.

Species is a term that refers to different animals and plants living in the environment. Organisms of the same species can reproduce with each other. Other species are different from the one species.

Evolution in every species occurs with time and environmental conditions for better survival in the environment.

Thus, it would take mammals between 3 million and 7 million years to evolve into a wholly new species. The alterations that take place will affect both the mind and the body.
