Answer: Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
Explanation:
A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study
Answer and Explanation:
Regarding genetics, the results of the study show that the mother's genetic material does not influence the behavior of rats in times of stress or in the biological responses of rats to these stressful moments. This is because the mice inherited their mothers' genes, but did not show the same results in a stressful situation when they were raised with different mothers.
Regarding epigenetics, however, we can see that the mothers' behavior in relation to the care of rats managed to provoke epigenetic changes that prevented or stimulated the expression of genes linked to stress, in these rats. The rats that were raised with attentive mothers showed a low expression of stress-linked genes, regardless of the biological mother they had. In addition, it is possible to notice that this modification is permanent, since the rats presented this same type of response throughout their lives.

If you cross an Aa individual with another Aa individual, what will the genotype ratio be in the next generation? What will be the phenotype ratio?
Answer:
Aa x Aa makes Aa because its a dominant gene. each square represents 25% so if u have 2 squares with Aa for example the ratio will be 2:4 (so 50%) if the gene is recessive then for the next generation it will go down to 25% unless another Aa allele is introduced in the next generation
Explanation:
Answer:
AA : Aa : aa Dominant : Recessive
Genotype ratio=> 1 : 2 : 1 Phenotype ratio=> 3 : 1
Explanation:
A a
A AA Aa

A place can support a population of 40 wolves. There are 55 wolves living in the area. What will happen to the wolf population?
Select one:
A. it will decrease.
B. It will remain the same.
C. it will increase very fast.
D. It will increase slowly.
Answer:
Well,if this place can only support a maximum amount of 40 wolves and 55 wolves are living in the area, the wolves population will decrease.

If a thin haired woman (bb) has a child with a full haired man (B-), then what is the chance each of their boys will be bald?
Please no files that I have to download
i did this in 6th grade and i think there is no chance because the thin haired woman has a non-dominant allele and the full haired man does have a strong allele. so, the man has the dominant gene
Why should organisms that produce more offspring have a more likely chance of survival?
Answer:Organisms must struggle to get what they need to survive, competing against other organisms that want the same things they do.
Explanation:
Answer:
I will try to put this in the simplest terms I can:
If you think about it, organisms actually do not live that long. There are multiple cause and effect reasons, such as low resources, no food, extinction, and so on. Thus, organisms must produce offspring to keep their "family line" consistent.
In this Punnett square used to predict genetic crosses, RR represents the _________ of the organism.A) appearance B) chromosomes C) genotype D) phenotype
Answer:
Genotype
Explanation:
A genotype is represented by two letters, called alleles, and describes the genes of an organism. Phenotype means the physical characterisitics of an organism. Chromosomes and appearance are irrelevant to this question. Hope it helps :)

how does greenhouse effect warm the earth?
Answer:
[tex]\color{Blue}\huge\boxed{Answer} [/tex]
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

Which organelle converts sugars into energy?
A. lysosome
B. mitochondrion
C. nucleus
D. ribosome
The organelle that converts sugars into energy is the mytochondrion, which is the powerhouse of the cell, so the correct option is B. mitochondrion
Which organelle converts sugars into energy?The mitochondrion is often referred to as the "powerhouse" of the cell because it is responsible for generating energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration.
During cellular respiration, glucose (a sugar) and oxygen are metabolized within the mitochondria to produce ATP, which serves as the primary energy currency of the cell. The mitochondria are present in most eukaryotic cells and play a crucial role in energy production.

Which of the following is a physical adaptation for the underlined animal?
Answer:
Physical adaptations do not develop during an individual animal's life, but over many generations. The shape of a bird's beak, the color of a mammal's fur, the thickness or thinness of the fur, the shape of the nose or ears are all examples of physical adaptations which help different animals survive.

Explanation:
what is meant by photosynthesis
Explanation:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Answer:
The process by which plants turn carbondioxide and water into carbohydrates and oxygen using light energy trapped by chlorophyll, is called photosynthesis.
