Answers
Answer:
answer is radon
Explanation:
........
Radon is naturally occurring gas can be found in certain rocks and soils and is considered a hazardous air pollutant.
What is Hazardous air pollutant?Those proven to cause cancer and other major health effects are considered hazardous air pollutants. According to the Clean Air Act, the EPA must regulate harmful air pollutants, or air toxics, coming from specific types of industrial operations in two phases.
Hazardous air pollution stationary source requirements are known as National Emission Standards for Hazardous Air Pollutants (NESHAP). The term "hazardous air pollutants" (HAPs) refers to airborne contaminants that are known or strongly suspected to be responsible for cancer, as well as other major health issues such birth defects or reproductive problems.
The EPA creates national enforcement programs that are centered on serious environmental concerns and patterns of noncompliance.
Therefore, Radon is naturally occurring gas can be found in certain rocks and soils and is considered a hazardous air pollutant.

B. It is a reflex response that causes various muscles to contract in order to move away from the object.
C.It is a conditioned response that occurs only to prevent injury!
D. It is a voluntary response that is initiated only after the impulse has been caried to the relevant area of the brain

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?
Answers
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 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
Answers
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.

Why should organisms that produce more offspring have a more likely chance of survival?
Answers
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.

The organism in the photo is a daphnia, or water flea. Daphnia are tiny aquatic organisms that live in most freshwater habitats. Adults range from less than 1 to 5 mm in length. They are good swimmers and eat mostly algae. Daphnia become mature at 5 to 10 days, and an adult female can produce up to 100 eggs every 3 or 4 days during its 2-month life span. When harmful algae rapidly increase in the daphnia environment, daphnia can develop adaptations to tolerate the negative effects of the algae within 10 years. What characteristic of the daphnia allows the population to adapt to environmental change
Answers
Answer:
The characteristic of daphnia which allows the population to adapt to the environmental change is the short generation time.
Explanation:
As evident from the text, the maturity comes in 5 to 10 days and they reproduce for the next 2 months at a rate of 100 eggs every 3/4 days. This is a short generation time which makes the evolutionary changes easy and less time-consuming to incorporate.

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.
