This passage describes the pod shape trait in pea plants:
Pea plants protect their seeds in pouch-like cases called pods. Some pea plants
grow inflated pods, which are smooth. Other pea plants grow constricted
pods, which are bumpy.
In a group of pea plants, some individuals have inflated pods and others have constricted
pods. In this group, the gene for the pod shape trait has two alleles. The allele for inflated
pods (D) is dominant over the allele for constricted pods (d).

1) Why did 40% of the human population evolve to tolerate lactose?(1 point)
A Lactose tolerance allows people to enjoy a wide variety of food, including milk, butter, ice cream, and cheese.
B People who have an intolerance experience physical pain, so a tolerance evolved to avoid that.
C Within cultures that rely on milk-producing animals, individuals who tolerated lactose had a survival advantage.
D Babies rely on milk to survive, so they need to be able to tolerate lactose.
2) What is the difference between genetic drift and natural selection?(1 point)
A Genetic drift is the change in a population’s genes over time; natural selection is the evolution of a population over time.
B Genetic drift is the frequency of genes in a population; natural selection is the frequency of adaptations in a population.
C Genetic drift is the random increase or decrease of certain genes in a population; natural selection is not random.
D Genetic drift is the selection of random traits in a population; natural selection is the selection of specific traits.
3 What is an interferon?(1 point)
A An interferon is used by a virus to stop the body from detecting it.
B An interferon disrupts DNA replication.
C An interferon reduces the efficacy of antibiotics on bacteria.
D An interferon activates the body’s immune system response to a virus.
4 Why is there such a wide variety of immune system responses between hosts when they are infected with the same virus?(1 point)
A Slight variations due to mutations in the virus trigger different responses in people.
B People that have already been infected are asymptomatic.
C Some viruses are resistant to antibiotics, so they cause a stronger immune system response.
D Each person’s immune system employs different tactics to get rid of the virus.
5 Is the following statement true? “Antigenic drift and other mutations to the DNA of viruses are always beneficial for the virus.”(1 point)
A Yes, because mutated viruses are able to infect more hosts.
B Yes, because mutated viruses have less mRNA so they can copy and replicate faster.
C No, because mutated viruses are may be less likely to replicate.
D No, because different mutations cause a variety of immune responses.
Answer:
1. D- Within cultures that rely on milk-producing animals, individuals who tolerated lactose had a survival advantage.
2. B- Genetic drift is the random increase or decrease of certain genes in a population; natural selection is not random.

Why does a substance like caffeine not bioaccumulate but heavy metals like mercury and lead do? Explain where these toxins are stored in the human body. Hint: is caffeine fat-soluble?
Answer:
Brain, heart, lungs, liver, kidney
Explanation:
Caffeine does not bioaccumulate in our body but heavy metals like mercury and lead can accumulate because caffeine are fat-soluble and broken down into simpler substances and used by the body whereas heavy metals are not fat-soluble and also essential for our body to function normally but when these heavy metals are very in concentration it accumulated in our body and causes several problems in our body organs. These heavy metals accumulation occurs in the organs such as brain, heart, lungs, liver and kidney where it cause problems.
Caffeine is in organic molecules that are metabolized by the liver. Heavy metals are atoms that cannot be broken down. They can be sequestered in the bones or in fatty tissue (with methylmercury) and have a long residence time in the body.
These toxins are stored in the human brain, heart, lungs, liver, and kidney.
What are heavy metals and examples?
The word-heavy metal directs to any metallic chemical element that has a relatively high density and is toxic at low concentrations.
Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), etc.
Thus, Heavy metals are atoms that cannot be broken down.

According to the flow chart, if blood glucose is low insulin is not released into the blood stream and A) insulin is secreted B) glucose is converted to insulin. C) glucose is not stored as glycogen D) glucose is absorbed in the blood stream
Answer:
C
Explanation:
If blood glucose is low, insulin is not released into the bloodstream and glucose is not stored as glycogen.
Insulin is only released by the pancreas when the glucose level in the bloodstream rises beyond the setpoint. When released, insulin converts excess glucose to glucagon and the latter is stored in body muscles and the liver. When required, that is, when the glucose level in the bloodstream falls beyond the setpoint, the glycogen is converted back to glucose by glucagon enzyme released by the pancreas.
The correct option is C.

ADP and P form ATP
Acetic acid is formed
Glucose is broken into pyruvic acid
CO2 is released from the reaction
AnswerA. ADP and P form ATP
Explanation:
Hope this is correct!
Answer:
ADP and P form ATP
Explanation:
The high energy is released in steps and picked up by ADP and P to form the high energy phosphate (ATP). For each two hydrogens passed down the chain, three ATPs are produced. At this stage, 36 ATPs are produced from the original glucose that started out in glycolysis. After the hydrogens have given up all of the excess energy they are combined with oxygen to form water. mark me brainy plz! (^_^)
