Having free earlobes (F) is a dominant trait in humans, and having attached earlobes (f) is Recessive. A Father has the genotype ff, and the mother has the genotype Ff. What is the fathers phenotype?
Answer:Attached earlobes
Explanation: As the phenotype is a visible trait, and the father has ff (a recessive trait) he has the attached earlobes.
Father has an attached earlobe because the father has both the allele in recessive condition.
What is phenotype?Earlobe attachment is a recessive feature, parents will be heterozygous for the character since the offspring has connected earlobes whereas both parents have free earlobes.
In humans, hypertrichosis of the ear is a holandric (Y-linked) trait, and connected earlobes predominate over free earlobes. A man who had long hair on his pinna and connected earlobes married a lady who had free earlobes.
With genotype ff, the person with attached earlobes can only generate e alleles. The person who has free earlobes and is heterozygous has the genotype Ff and is capable of producing both the Fand f alleles.
Therefore due to the recessive condition father shows an attached lobe phenotype.

Does reproduction always create individuals with adaptive traits?
Answer:
Yes
Explanation:
Adaptive traits are traits posses by organism that help them to survive well and reproduce in their environment.and reproduction is a biological process which lead to the creation of new offsprings or organisms from the parent.
Reproduction create individual with adaptive traits this is because, adaptive traits or traits generally are heritable or can be pass from parent to the offsprings. Once parent posses adaptive traits that give them ability to , survive and adapt to their new environment, once they reproduce , it can be transfer to their offsprings.

Male tungara frogs make a loud distinctive call at night to attract mates. The nocturnal fringe-lipped bat, which preys on this species of frog, detects these calls. Which of the following statements most accurately describes how this
situation is an example of an adaptation that improves reproductive success for a species?
A. The frog has an adaptation to evade capture by one of its
predators, which helps ensure survival through its reproductive stage.
B. The bat has an adaptation that allows it to more easily locate prey, which helps ensure that it has energy needed for reproduction.
C. The frog has an adaptation that increases its ability to survive until it can mate and produce offspring.
D. The bat has an adaptation that allows it to cooperate with the frog so that the bat is better able to survive as a nocturnal species.
Answer:
B
Explanation:
Because the frog's call can attract the bat, they don't often live long enough to find a mate with said call. However, making a meal of the frog provides the bat with energy to help it with it's reproduction.

Option C. Crust is destroyed. at a convergent boundary.
A convergent boundary (additionally known as an unfavorable boundary) is an area on the earth in which two or greater lithospheric plates collide. One plate finally slides underneath the alternative, a procedure referred to as subduction. The subduction quarter can be described by using an aircraft where many earthquakes occur, known as the Wadati–Benioff region.
Convergent boundaries are the collision of the Indian Plate with the Eurasian Plate, creating the Himalayas Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of tiers extending from the Alps in Europe to the Zagros Mountains in Iran.

What is the rate of motion of the Amur plate? Express your answer in Year
Where would the plate be after 1 million years? Express your answer in m
What geologic feature will form between the Amur and Eurasian plates?
to part A the answer is :5 mm/year
to part B the answer is: 5,000 meters east
and finally for part c the answer is new ocean floor
Hope I helped :D
The rate of motion of the Amur plate is 0.005 meters (m) per year; whereas the plate will move 5,000 meters (m) east after 1 million years. Moreover, a NEW OCEAN FLOOR will form between the Amur and Eurasian plates.
The rate of motion (R) can be calculated as:R = 125,000 meters (m) /25,000,000 years = 0.005 m/year
The movement of the plate can be estimated as:1 year _____________ 0.005 m east
1,000,000 years ____ X = 1,000,000 x 0.005 >>
X = 5,000 meters east
It is well known that new seafloors are continually formed in regions where oceanic plates move apart during seafloor spreading. In this case, a new ocean floor will form between the Amur and Eurasian plates.In conclusion, the rate of motion of the Amur plate is 0.005 meters (m) per year; whereas the plate will move 5,000 meters (m) east after 1 million years. Moreover, a NEW OCEAN FLOOR will form between the Amur and Eurasian plates.

Mendelian inheritance does not apply to the inheritance of alleles that result in incomplete dominance and codominance.
Why? How are the alleles in these two situations different from the alleles that Mendel studied?
Answer:
Explanation:
Phenotypes that Mendel studied was controlled by one gene that had two possible alleles, dominant and recessive allele. This made it possible to see just one or the other phenotype (total of 2 phenotypes).
Well now we know that a characteristic may be controlled by one gene with two alleles, but the two alleles may not have a traditional relationship of dominant and recessive. Which is why we see the patterns like codominance and incomplete dominance.
Codominance is when both alleles are expressed equally in the phenotype of the heterozygote. For example, you have a black flower and red flower, a codominant flower would have both black petals and red petals. Do you see how the traditional relationship of one being dominant and other being recessive no longer holds because you express both alleles.
Incomplete dominance occurs when the phenotype of the offspring is somewhere in between the phenotype of both parents. SO a black and red flower would make an offspring with purple petals where neither of the alleles reigns supreme over other rather we get a mixture of both alleles.
The passing of the alleles from the parent to the offspring in a particular manner was given by Mendel, he defined the passing of the recessive and the dominant allele in a specific way from generations.
Mendelian inheritance does not apply to incomplete and co-dominance.
The exception of the Mendelian inheritance can be explained as:The condition in which the allele is not completely expressed in the progeny is called incomplete dominance while the expression of both the recessive and the dominant allele in the progeny together is called co-dominance.In the co-dominance case of hetero-zygotic phenotype, the allele is depicted equally. The law of recessive and dominance does not apply here and both the alleles are expressed in the progeny in equal ratio.In the incomplete dominance condition, the phenotypic character of the progeny is in the middle and a mixture of both the dominant and the recessive allele.Therefore, the Mendelian inheritance law does not apply to incomplete dominance and co-dominance.
