Dr. Mrs. Brown has Rh+ blood, but her father is Rh-. What must her full blood type genotype be?
Answer:
Her full blood type genotype is Dd.
Explanation:
Rh (Rhesus) factor is a type of protein found on the outside of red blood cells. It is genetically inherited. An individual that has this protein is Rh-positive, and the one that doesn't is Rh-negative. The Rh-positive gene is dominant, while the Rh-negative gene is recessive. This means that a person must inherit at least one dominant (D) allele from their parents in order to be Rh-positive.
If Dr. Mrs. Brown is Rh-positive, and her father is Rh-negative, her mother must be Rh-positive (DD or Dd), as well. Her father has two recessive alleles (dd), which means that Dr. Mrs. Brown must have one recessive allele. Since she is Rh-positive, she must have one dominant allele. This makes her genotype Dd.

Scientific evidence shows that modern dogs, wolves, and foxes all have a common ancestor. Further evidence shows that dogs are more closely related to wolves than to fixes. Which of the following observations provides the BEST evidence that dogs are more closely related to wolves than to foxes? *
A. The diets of dogs and wolves are more similar that the diets of dogs and foxes.
B. The lifespans of dogs and wolves are more similar than the lifespans of dogs and foxes.
C. The genetic sequences (DNA) of dogs and wolves are more similar than the genetic sequences of dogs and foxes.
D. The body sizes of dogs and wolves are more similar than the body sizes of dogs and foxes.
The observation that provides the best evidence that dogs are more related to wolves than to foxes is the DNA sequence of dogs and wolves being more similar than that of dogs and foxes.
The DNA is a molecule that stores the genetic information of organisms. Thus, closely related organisms have similar information on their DNA, usually indicated by similar nucleotide sequences.
Therefore, if dogs and wolves are more closely related in ancestry than dogs and foxes, the DNA sequence of dogs and wolves will be more similar than the DNA sequence of dogs and foxes.

Which statement illustrates bias in scientific research?(1 point)
A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.
B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.
C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.
D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.
Answer:
D
Explanation:
The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)
In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:
The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interestScientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.
According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.

Imagine you are studying a population of finches on one of the Galápagos Islands. You have been recording many of the birds' physical traits, including the length of both wings. You observe that for 80% of individuals measured, the length of the left wing is not significantly different from the length of the right wing (in other words, they are symmetrical). But for about 20% of birds measured, the wing lengths are asymmetrical. This distribution is true from generation to generation. Suddenly, a rare 5-day windstorm takes over the island. After the storm, you spend the next several days netting each bird on the island that survived the storm. You discover that 85% of the birds with symmetrical wings survived the storm, whereas only 5% of the birds with asymmetrical wings did.
a. Propose a hypothesis to explain this observation.
b. If such storms become increasingly common due to changes in climate, how might you expect the population to change over time with respect to wing symmetry? The distribution of symmetrical to asymmetrical will change so that close to 100% of birds will have symmetrical wingspans.
Answer:
a) The change in the character of an organism relies upon the ability of the adaption on the base of the external change or the environment change, "An organism that is not able to adapt accordingly would not survive and eliminated from the population."
b) In the given case, Symmetric wings are far more suitable for the survivorship as it provides better flight than the organism with asymmetric wings, it is also given that there is 20% of the population have asymmetric wings.
After the storm which is selection pressure, there is the elimination of the entire bird population with asymmetrical wings from the ecosystem so the final frequency would be 100% of the entire population with symmetrical wings.
Natural selection benefits the phenotype that increases the fitness. a) Symetrical wings increase the fitness of finches because they are better to face selective pressures. b) natural selection will favor symmetrical wings.
-------------------------------------
a) Hypothesis:
Symmetrical wings increase the fitness of finches because these type of wings are better to face selective pressures like severe windstorms.
b) If such storms become increasingly common with time, natural selection will favor symmetrical wings by increasing its frequency in the population, while animals with asymetrical wings will decrease to near cero.
Natural selection is an evolutive force that selects beneficial alleles and increases their frequency in the population. It is the result of the phenotype-environment interaction which determines gene destiny in space and time. Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation. Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. Adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats. The selective agent is the environmental trait that determines the differential survival of the phenotypic classes. The environment influences the probability that each genotype passes its gametes to the next generation.So in this example,
⇒ The strong storms are acting as selective pressures.
⇒ This selective pressure is modeling the phenotype of finches.
⇒ Natural selection favors the phenotype that performs better when facing storms.
⇒ Symmetrical wings are the phenotype that better suits and increases the animal's fitness.
⇒ Hence, natural selection favors this phenotype over asymmetrical wings.

In tomatoes, red fruit color is dominant, R, to yellow fruit color, r. A farmer has tomatoes that produce either red or yellow tomatoes. He has signed a contract with a large seed company to provide pure, RR, and pure yellow seeds, rr. They do not want any hybrids. How could the farmer tell if his tomatoes are pure or hybrid?
Answer:
He should perform a "testcross" by crossing the tomatoes in question with yellow-fruited plants.
If they are pure, all offpsring will be Red: RR x rr = all Rr
If they are hybrids (heterozygous), half the offspring will have yellow fruits: Rr x rr = 1:1 (red to yellow)

Why is uranium lead dating better than radiocarbon dating?
Answer:
Uranium-238 has a much longer half-life of 4.5 billion years versus Carbon-14's 5,730 years.
Explanation:
Radioactive Carbon-14 or [tex]^{14}C[/tex] is typically formed in the upper atmosphere. In plants, it gets incorporated into organic molecules through photosynthesis, and this material is ingested by consumers.
It is used for the process of radiocarbon dating of fossils and formations. Radioactive isotope dating is an effective means of identification due to the unstable nature of the isotope used and the predictable rate of decay.
Over time they decay to give off an electron, in an effort to become a more stable element. For instance, [tex]^{14}C[/tex] has a relatively short half-life and half the in a sample becomes Nitrogen over a few thousand years (5,730 years).
However, for older samples, other isotopes are used because their long half-life may range between a million to billions of years. Uranium-238, with a half-life of 4.5 billion years is often used in geochronology; uranium-lead dating is suitable for older specimens.

C
Explanation:
The exerpt states that movements in the Earth's crust (unbalance) causes Earthquakes. When it's balanced, there is no plate movement.
Answer: c
Explanation: if there is no plate movement that means that there is a balanced force there is nothing that is disrupting it. but if there's an earthquake in that means that there are unbalanced forces in that they cause an earthquake. a force is balanced if the two individual forces are of equal magnitude and of the opposite direction. And an object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
