Label the diagram below
Answer:
1. cuticle
2. leaf epidermis
3. leaf xylem
4. guard cell
5. leaf epidermis
6. stoma
7. root hair
8. ground tissue (xylem vessel)
Explanation:
functions of :
stomata aid in losing of water during transpiration
guard cells regulate the opening and closing of the stomata .this happens when the guard cells have a hypertonic environment they absorb water from the neighboring cells hence they expand and the stomata open .during the night the sugar levels in the guard cells have dropped hence they lose water to the neighbouring cells hence they shrink become flaccid and the stomata close.
xylem transports water to various parts of the plant
cuticle is a thin waxy and transparent layer.it is shiny to reduce excessive loss of water and it is transparent to allow light to penetrate through
root hairs are thin ,long and flexible.they are thin to reduce distance covered by diffusing water,they are long to allow their ability to tap water from underground,they are flexible to increase their ability to reach water sources .

Why does PE = mgh equal PE = Fw h ?
Answer:
Why is potential energy MGH?
Potential energy is energy an object has because of its position relative to some other object. ... For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

3. Callie has brown eyes, but her husband Joseph has blue eyes. All three of their children have
brown eyes. Do you know what Callie's genotype is? If yes, what is it? If no, why not?
Help please!!
Answer:
Since Callie has brown eyes, and all her children have brown eyes, we can only assume that the phenotype of brown eyes is dominand and Callie will have a dominant genotype, leaving Joseph to have a reccesive genotype (if Joseph was heterozygous for this aspect, he would have brown eyes) and the children will be heterozygous, with brown eyes as this characteristic predominates over blue eyes.

All human body cells contain 46 chromosomes. However, sperm cells in men and egg cells in women have only 23 chromosomes. This is due to meiosis. How does meiosis accomplish the reduction in chromosomal number?
Answer:
Two cell divisions after DNA replication
Explanation:
After the DNA is replicated, the cell undergoes two rounds of meiosis to produce 4 cells, each wIth 23 chromosomes. This is how the cell goes from a diploid to a haploid state.

The speed at which waves approach the shore depends on the shoreline features and the depth of the sea floor. When a wave reaches the shore, it releases a burst of energy that generates a current which runs parallel to the shoreline. What is this current called?
Answer:
Longshore current.
Explanation:
A wave is a disturbance which travels through a material medium without any permanent displacement of the particles of the medium. During the propagation of a wave, energy is transmitted from one point to another since waves flow with energy. The higher its speed of propagation, the higher the energy of the wave.
The energy released by the wave at shore produces a current which is referred to as a longshore current.
Answer:
It would be Longshore Current

b) Describe the role of the digestive enzymes and the factors that affect their function (1 points)
HINT: Think about the effect of enzymes on large macromolecules and what causes enzymes to
change
Answer:
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion. An enzyme's shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape.

Donna has observed that her father can control the speed of their grandfather clock by adjusting the
height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster when
the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the time it takes
for the pendulum to swing twenty times when the weight is moved to its lowest position. Donna begins to
move the pendulum up by 1 cm and continues to measure the time for twenty swings of the pendulum.
Donna records her data.
The missing part of the question is as follows:
Position Time (seconds)
1 23.23
2 21.56
3 20.33
4 19.00
5 18.02
Hypothesis: ____________
Dependent Variable: ____________
Independent Variable: ________________
Constants: __________
Control Group:_________________
Experimental Group: ____________
Answer:
Hypothesis:
if the weight is lowered the pendulum will move faster
Dependent Variable:
Time it takes the pendulum to swing or move
Independent Variable:
the position of the weight
Constants:
same weight and the same number of swings
Control Group:
pendulum at the lowest position
Experimental Group:
different height of pendulums
Explanation:
A hypothesis is a possible explanation for the observation in a given experiment which is "if the weight is lowered the pendulum will move faster" as it states the effect of length of the pendulum on the time it takes to swing.
The dependent variable in an experiment is affected and measured to see the effect which is the time it takes the pendulum to swing or move which is measured here and affected by the independent variable that is the position of the weight.
Constants are the variable that remains constant throughout the experiment that is the same weight and the same number of swings. Control group is the group of subject or condition which minimize the effect of factors or variables except one factor to compare or ensure if the experiment works that are pendulum at the lowest position. The experiment group is the group of a subject that get treatment desired to influence the dependent variable that is the different height of pendulums.
