A forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine? The number of adenine bases will be equal to the number of guanine bases. The number of adenine bases will be equal to the total of all the other bases. The number of adenine bases will be equal to the number of thymine bases. The number of adenine bases will be half of the number of cytosine bases.

Select the correct statement about olfaction. a) Olfactory adaptation is only due to fading of receptor cell response. b) Olfactory receptors have a high degree of specificity toward a single type of chemical. c) Substances must be volatile and hydrophobic in order to activate olfactory receptors. d) Some of the sensation of olfaction is actually one of pain.

Answers

Answer:

Some of the sensation of olfaction is actually one of pain. (Ans D)

Explanation:

Olfactory system is also known as sense of smell, is called the sensory system used for olfaction (smelling). It is known as the special sense, which have directly association with specific organs. Most reptiles, and mammals contains 2 types of olfactory system:

1) Main olfactory system: It helps in detection airborne substances.

2) Accessory olfactory system: It helps in sense fluid phase stimuli.

HELP ASAP In a breed of dogs, the BbEe genotype gives rise to yellow fur color, the Bbee genotype gives rise to black fur color, and bbee gives rise to brown fur color. Which of the following terms can be used in categorizing this inheritance pattern? A. codominance
B. incomplete dominance
C. multiple alleles
D. polygenic

Answers

Answer:

The most appropriate polygenic.

Polygenic trait refers to the trait which is controlled by two or more genes.

For example, height and skin color.

In the given breed, the phenotype of fur color is controlled by the interaction of two genes; gene B and gene E.

Thus, it is an example of polygenic inheritance.
Codominance means both exist

Incomplete means mix of two

Multiple alleles is when theres more than 2 like for describing blood type

So the answer is polygenetic!

A news article discussing the evolution of domestic dogs from wolves included this statement: "On its way from pack-hunting carnivore to fireside companion, dogs learned to love-or at least live on-wheat, rice, barley, corn, and potatoes." What is more scientifically accurate way to state what happened with dogs?A) Dogs were created at the same time as wolves.
B) Being around humans represented an advantage, so wolves were able to take advantage of that by changing their digestion to be able to eat wheat, rice, barley, corn, and potatoes.
C) Dogs mutated to be able to eat wheat, rice, barley, corn, and potatoes.
D) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.

Answers

Answer:

The correct answer will be option-D

Explanation:

The studies done by the scientist led to the conclusion that the doges were evolved from the wolves,

The interaction of the wolves with humans became symbiotic around 10000-15000 years ago when the wolves in search of food changed themselves and adapted to survive with humans.

The studies on the genes of Dog shows that the gene responsible to digest carbohydrate called amylase starting duplicating in Wolves allowing them to digest carbohydrate cereals offered by humans. Their pancreatic enzymes also got modified to digest the carbohydrate-protein rich cereals.

Thus, option-D is the correct answer.

Which of the following questions can be answered scientifically? 1) Should we just let the river flow where it wants? 2) What can be done to stop erosion? 3) Is erosion control worth the financial costs? 4) Can planting cover crops reduce erosion?

Answers

4 is a good answer. The question ‘can planting cover crops reduce erosion’ can be easily answered by creating a scientific study. You could create an experimental group where cover crops are planted and a control group where they are not, and measure the erosion of each group.

Answer:

The answer is D, Can planting cover crops reduce erosion?
