Answer:
The fruiting bodies of fungi grow on wood chips, shredded bark and other mulches, and the resulting mushrooms may look unsightly but are mostly harmless. Fungi help break down dead organic matter, providing nutrients for plants. The mushrooms they grow emit spores that spread the fungi to new areas.

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.
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
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.

a problem that confounds attempts to organize the entire living world for study?
Answer:
A problem that confounds attempts to organize the entire living world for study is the need of evolutionists to bring the entire diversity of living things ultimately into.
In biology, living things can all be classified in accordance with other living things that share a specified set of common characteristics. A major challenge to the process of classification is that, in evolution, that this involves the need to classify all living things. The challenges being that there are many species on planet earth that once existed and are now extinct (i.e. they cannot currently be studied in living form) and that there may be species that do exist that have yet to be discovered and therefore cannot be classified. Finally, due to the sheer number of species on earth, it will literally take hundreds of years for scientists to classify all species.

How are impulses received to the brain? Step-by-step???
So, impulses are basically reactions from something else. So, in the brain, there are neurons, which are also known as brain cells. They have two main and really important parts, called the dendrite and the axon. The dendrite receives the impulse, either from the central nervous system (CNS) or from the peripheral nervous system (PNS). After this event, the axon transfers and carries the impulse away from the cell body. Also, the impulse travels through a little gap in between neurons called the synapse, before the impulse travels to the next neuron. And, remember, this process is not slow. This process occurs in a matter of milliseconds. Think about it. If you burn your hand from something really hot, you will react to that really fast as an impulse. Millions of neurons will react to that in just a second. That's why science is so cool. It has so many interesting topics and fascinating facts, like this. Anyways, I hope this helped you. Enjoy your day.
Dendrites get impulses. Axons carry impulses.
