Mrs. Jones has type B blood. Her mom has type A and her dad has type B. What must her mom's genotype be?
Answer:
I^Ai
Explanation:
because she can't have both dominant A's. if she had, jones were AB
If Mrs. Jones has type B blood and her mom has type A and her dad has type B, so iAi is the genotype of her mom.
What is genotype?It is the representation of genetic content of an organism, iAiA genotype shows type A blood group, it is the sum of gene that is transfer from parents to offsprings.
If cross between father having type B blood group and mother type A blood group having genotypes of iBiB and iAi.
Cross: iBiB X iAi
Gametes: iB, iA and i
Genotypes of the offsprings: iBIA, iBi, iBIA, iBi
Phenotypes: AB, B, AB and B.
The cross is attached in the image below.
If only mom's genotype is iAi, is crossed with iBiB, so the children have probability for having blood group B.
Therefore, iAi is the genotype of her mom, makes the possibility for Mrs. Jones to have type B blood.

Which statement is TRUE?
1)Light waves always travel at a constant speed, but sound waves do not.
2)Waves travel at different speeds through different materials.
3)Wave speed depends on the amplitude of the wave.
4)Light waves and sound waves travel at the same constant speed.
Answer:
C. Is correct
Explanation:
For a sound wave it depends on how much compression the loud speaker or musical instrument creates. In other words, it depends on the energy the source put into the wave. It does not depend on frequency, wavelength, or velocity.
The correct answer is option 3 as it explains Wave speed depends on the amplitude of the wave.
In the case of sound waves, it depends on how much compression the speaker or instrument produces. In other words, it depends on the energy the source puts into the wave. It does not depend on frequency, wavelength, or speed.
Wave amplitude does not affect the speed at which the wave propagates. Wave velocity depends on both wavelength and wave frequency. Most wave velocities depend on the medium or substance through which the wave passes. Sound waves travel faster in air and water than in solids and gases.
What is wave amplitude?Amplitude, in physics, is the maximum displacement or distance that a vibrating object or point on a wave has moved, measured from an equilibrium position. This corresponds to half the length of the vibration path.
Hence it concludes that Wave speed depends on the amplitude of the wave.

What is an example of a codominate
phenotype?
Answer:
With a codominant trait, phenotypes like fur color are combined. For example, if a black-feathered chicken breeds with a white-feathered chicken, their offspring will be both black and white. They will not be gray; rather, there will be spots of both colors. Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

Describe one water cycle process you have learned about and tell how it shows that the water cycle
connects nonliving and living things.
Answer:
Explanation:
The water evaporates from the lake to form a cloud(condensation).it starts to rain(precepation)then collects back in lake.precipitation connects with living things by watering them.it also connects nonliving by processes such as evaporation, precipitation, water returns back into the atmosphere.

What is the energy source for producers, consumers, and decomposers?
Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Explanation:
A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.
What is Dichotomous key?More details regarding the unique characteristics of a given organism are disclosed with each successive division. Once the organism no longer exhibits all of the chosen traits in concert with any other organism, it has been recognized.
In order to identify specimens with a dichotomous key, it is recommended to employ immutable traits (i.e. features that do not change). Size, coloration, and behavioral habits can all change across people and over the course of a lifetime.
Better traits are produced by physical features (like the number of limbs) and biological processes (like the mode of reproduction). Typically, dichotomous keys are displayed in one of two ways.
Therefore, A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.

Answer:
1/4 will have ss trait
Explanation:
other 2/4 will be carrier(Ss) and other 1/4 will have both dominant trait (SS)
Answer:
B. 1/2
Explanation:
The genotypes of the parents are Ss and Ss. We know this because Heterozygous basically means different alleles. The punnet square of this problem will show that the possible genes given to the offspring are SS (capital letters mean dominant. keep in mind that sickle-cell anemia is a recessive trait, meaning it is written in lowercase), Ss, Ss, or ss. So this means the offspring will have a 1/2 chance of becoming heterozygous (Ss).
