In cats, long hair is completely dominant to short hair. Jack the cat, his mother, and his sister are all short-
haired cats. With just this information is it possible to know if Jack's dad is a short hair or long hair cat? Why
or why not?
his dads hair is short.
if long hair is completely dominant then Jack's hair would be long if his dads hair was long.

Select TWO processes that are MOST LIKELY to cause the variation in bird beak size traits within this
population
A. Asexual reproduction
B.Hibernation
C.Sexual reproduction
D.Migration
E.Mutation
The two processes that are most likely to cause the variation in bird beak size traits are ; ( C and E )
sexual reproduction ( C ) Mutation ( E )The Random Mutation occurring in birds due to the environmental factors and food availability in an area will to lead to the varying changes seen in the size of beaks of the bird within a population. long beaks are used to pick out food from cactus plants while short strong beaks are used to pick out food underground.
Sexual reproduction between birds with varying genes will lead to the formation of varying beak sizes traits seen within a given bird population.
Hence we can conclude that the two processes that are most likely to cause variation in bird beak size are ; sexual reproduction and mutation.

Answer:
The correct answer is - Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment.
Explanation:
In any scientific knowledge development process, scientists need to follow the scientific process in a particular sequence that helps in developing and testing a hypothesis.
The sequence has:
observation: Observation requires you to pay attention to occurrences around
Forming question: on the basis of observation form a question about why that occurrence happens.
Hypothesis formation: The hypothesis is your initial prediction on why that happens.
Experiment: The experiment is being done in order to collect data and analysis so you can test your hypothesis

Which of the following descriptions is MOST plausible for an ancestor of bats? An animal with-
A: two limbs and webbed toes.
B: a long tail that ate insects and lived in forests.
C: four limbs and a membrane consistent with gliding.
D: four fins that glided through the water.
Answer:
C
Explanation:
Four limbs and a membrane consistent with gliding are the structures found in ancestors of bats. Therefore, option (C) is correct
What is patagium?A membrane called the patagium helps animals glide or fly. Bats, birds, dromaeosaurs, pterosaurs, gliding mammals, flying lizards, and flying frogs have the structure. The uropatagium (particularly in bats) or interfemoral membrane connects an animal's hind limbs.
Bats' wing skin extends from the abdomen to the tip of each digit, connecting the forelimb to the body. Bat patagiums have four parts:
Propatagium: neck-to-first-digit patagium.Dactylopatagium: digits.Plagiopatagium: between final digit and hindlimbs.Uropatagium: posterior flap between hindlimbs.Therefore, option (C) is correct.

How do large bodies of water affect the climate of a region?
Answer:
Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range.

The graph represents the distance a car travels over time while on the highway. Which statement about the car's trip is accurate?
A)
The car does not move over time.
B)
The car travels at a constant velocity.
The car's velocity increases constantly over time.
D)
The car's velocity decreases constantly over time.
Answer:
B
Explanation:
The chart is going up and up which means the car goes up and up in speed and velocity and is very consistant
The statement that is accurate regarding the car trip is that it travels at a constant velocity. The correct option is B.
What is velocity?Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.
The rate of change of displacement is known as velocity. The rate at which velocity changes is called acceleration.
Due to the fact that it includes both magnitude and direction, velocity is a vector quantity. As the rate at which velocity changes, acceleration is likewise a vector quantity.
An object must move at a consistent speed and direction in order to have a constant velocity.
The object can only move in a straight line if the direction is constant. So, motion in a straight line at a constant speed is defined as having a constant velocity.
Thus, the correct option is B.

Explanation:
Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Since all these offspring only have one trait for long fur, this trait stays hidden in their DNA and is not expressed in their phenotype. All the offspring will have short fur.
Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Answer:
test two:
some short fur and some long fur will be seen.
this is because in some cases, the offsprings have only have the trait for short fur or just one trait for long fur and so short fur is expressed in the phenotype. in other cases, the offsprings have only the trait for long fur and so long fur is expressed phenotypically.
test three:
all long fur is seen.
since all the offsprings only have the trait for long fur and no trait for short fur, long fur is expressed in the phenotype.
Assuming a diallelic gene coding for the trait and expressing complete dominance, 1) all short fur. 2)some short and some long fur. 3) all long fur.
According to the information that was provided, we can assume that the trait fur length is coded by a single diallelic gene
• dominant allele F codes for short fur
• recessive allele f codes for long fur
We can also assume that the gene expresses complete dominance.
What is complete dominance?It is the inheritance pattern in which the dominant allele completely masks the recessive allele.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant phenotype. The dominant allele is hiding the expression of the recessive allele.
Many genes show complete dominance.
Cross 1:
Parentals) FF x Ff
F1) 100% short fur
All short fur
Cross 2:
Parentals) Ff x Ff
F1) 1/4 FF + 1/2 Ff / 1/4 ff
75% short fur + 25% long fur
Some short fur, and some long fur

What process contains the enzymes that break the chemical bonds in your food in order to create usable energy?
Answer:
Cellular respiration
Explanation:
This is because cellular respiration is an aerobic process where the chemical bonds in food are broken down to release energy. This process produce energy which are useful for the body cells. Cellular respiration help to break down glucose. Glucose and oxygen are converted to carbondioxide and water and energy is released which form ATP.
