Sudhi is studying the motion of a toy car. She places the car in the middle of a ramp and releases it.
Hello. Your question is incomplete. However, when researching, I managed to find a question like yours and found that you forgot to mention that the question wants you to determine which is the best reference point in this scenario.
Answer:
The best point of reference is the starting position of the toy car.
Explanation:
To study the movement of the car it is necessary for Sudhi to establish a reference point, so that she can calculate all the variables associated with this movement. The best variable in this scenario is the starting position of the car, when it is still on the ramp. Thus, Sudhi needs to determine the distance between the car and the ground, that is, what the car's starting position is. She will be able to discover this when determining the height of the ramp.

When a trait is always expressed, it is considered to be a
trait.
O Recessive
O Codominant
O Dominant
O Incomplete
Answer:
O Dominant
Explanation:
An allele that is always expressed whenever it is present is called dominant. Mendel's law of segregation states that the two alleles for a trait segregate independently when gametes are formed.
Hope this helped!!!!!
A dominant trait is a form of trait which is ALWAYS expressed.
An organ can be defined as
a) A group of cells of one type that has a function
b) a group of several different cell types, each type working together
c) a group of tissues that are located together that have unrelated functions
d) part of a system and therefore does not have a function of its own
Answer:
C...................
Answer:

A park guide tells her that hoodoos like this one have been forming on Earth throughout history. Which principle explains the process that forms these rocks? A. erosion B. deposition C. weathering D. uniformitarianism
The principle that explains the process of forming hoodoos like this one is erosion. Therefore, option (A) is correct.
A hoodoo is a tall and thin rock formation characterized by a column of sedimentary rock that has been eroded over time, leaving a pinnacle or spire-like structure. Hoodoos are typically found in arid or semiarid areas with a high concentration of soft rock such as sandstone, limestone, or volcanic tuff. These formations are often created by a combination of factors such as water erosion, wind erosion, and frost weathering.
Hoodoos can take on various shapes and sizes and may be found singly or in groups, forming intricate and awe-inspiring landscapes. They are commonly found in national parks and other natural areas around the world, including the United States, Canada, China, and Australia, where they attract tourists and geology enthusiasts alike.

In a lake with three trophic levels (non-native fish, zooplankton, algae), an algal bloom occurs when the small population of zooplankton declines due to the predation of the invasive fish. Which of the following describes why zooplankton are the keystone species in this scenario?
Zooplankton are the smallest of all the herbivorous marine mammals in their communities.
The small population of zooplankton have an unequal effect on the marine community.
Marine mammals depend upon the work of zooplankton to convert sunlight into food.
Zooplankton help other populations survive by keeping out other herbivores.
Answers:
Zooplankton help other populations survive by keeping out other herbivores
Explanation:
This is because a keystone species are species that have large effect on the the habitat and through its effect they help to keep the ecosystem in existence. They make sure that the ecosystem exist. They help populations survive by keeping out herbivores and feeding on the algae. They help drive nutrients cycle and transfer energy from algae to invasive fish.

What are examples of things that can cause mutations?
Answer:
Exposure to chemicals.
Explanation:
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations. Hope this helped. :D

Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose father had blue eyes. Figure out each member’s genotype
Answer:
Man: Bb
Man’s mother: bb
Woman:Bb
Woman’s father: bb
Explanation:
Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.
Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn’t occur?
Answer:
Due to exchange of parts of chromosome.
Explanation:
Crossing over is the exchange of segments or parts of chromosome between non-sister chromatids in the meiosis cell division. Due to crossing over, new combinations of genes in the gametes are formed that are not found in both parent which leads to genetic diversity. Crossing over affects the expression of certain traits in the organism because the organism that crossing over have different features as compared to their parents so there is a big difference between organism have crossing over and no crossing over.
